Description: TECHNICAL FIELD [Detailed description of the invention]

【0001】

[Technical field to which the invention belongs]

The present invention relates to a SIM card connector used for a mobile phone or the like, and relates to a multi-directional insertion type connector capable of inserting a card from at least two directions.

【0002】

[Conventional technology]

Conventionally, a connector as shown in FIG. 7 has been proposed (see Japanese Patent Application Laid-Open No. 2000-36349, hereinafter referred to as Conventional Technique 1).

【0003】

FIG. 7 is a perspective view of the contactor support of the connector, FIG. 8 is a perspective view of the first contactor, and FIG. 9 is a perspective view of the second contactor.

【0004】

The contact support 110 shown in FIG. 7 is made of a plastic insulator 112, in which a first group 114 with six contacts 116 and a second group with two contacts 120 are included. 118 and are arranged.

【0005】

The insulator 112 has a rectangular parallelepiped shape with a first contact group 114, a rectangular parallelepiped shape first portion 112q followed by a connecting portion 112v, and a rectangular parallelepiped shape dislocated from the portion 112q. There is a second part 112z of, the lower side of the part 112z is aligned with the lower side of the part 112q, and the surface 112zo of the part 112q, however, protrudes above the surface 112q'o of the part 112q. This forms an edge 122, which acts, for example, as a stopper edge for a chip card (not shown) inserted in the P direction to determine the final position of the card.

【0006】

This edge can also be formed on the surface 116qo, as shown by the dashed line at number 122' in FIG. At this time, the contact 120 of the contact group 118 can be used to indicate the locked state or the read ready state of the chip card, in which case the contact 120 is activated in parallel with the insertion of the chip card. A slider (not shown) descending onto the contactor 120.

【0007】

The configuration and contact method of the contactor 120 at that time are the same as the configuration of the contactor 116 described below.

【0008】

Each contact 116 has a meander shape, as shown in FIG. 8, and at least the central part is made of a spring-shaped sheet metal.

【0009】

At the upper free end of each contact 116 is a horizontal plate 116.1, followed by a spoon-shaped, bidirectionally curved contact 116.2, beyond which (at 24 and 26) 2 It is followed by a bent spring-like part 116.3, which widens as part 116.4, almost below the contact part 116.2, then bends about 90 degrees and continues further to part 116.5, and again about 90. Continuing to the bent part 116.6, this end part is separated by a horizontal plate 116.7, which narrows in a wedge shape towards the free end.

【0010】

The insulator 112 is formed corresponding to the shape of the contact 116. The insulator 112 has six dents 128 that are open toward the surface 112qo and sides to accept parts 116.1 to 116.4 of the contacts 116, and below that, under 112qu to receive parts 116.6 and 116.7. There are 6 slits running parallel to the side, but when installing each contactor 116, a certain initial stress is applied to the wedge-shaped horizontal plate 116.7 at this part, and the contactor 116 part 116.6 is applied. Arrange them on almost the same plane.

【0011】

When mounting the side of the contactor 116, parts 116.1 to 116.4 are guided to the dent 128, in which case the following positioning or block mechanism works.

【0012】

In the above portion 116.4 of the contact 116, there is a tongue piece 116.4z that protrudes downward in a spring shape, and when the free end of the tongue piece 116.4z passes through the corresponding recess in the dent 128, the tongue piece. Part 116.4z snaps into this recess.

【0013】

Part 116.3 is guided to the corresponding notch groove in the part of the dent 128, which and the tongue piece 116.4z prevent it from moving in either the direction x of the arrow or the direction y of the arrow. Become.

【0014】

The horizontal plate 116.1 abuts against a protrusion 132 on the side of the recess 128 when attaching the contact 116, which creates a corresponding initial stress and positions the free end of the contact 116 in the arrow direction x. At the same time, the guide wall 134 on the side surface of the dent 128 allows the contact 116 to be positioned in the arrow direction y.

【0015】

In such an embodiment, the chip card can be guided in the x and y directions, but at that time, the contacts and particularly the contact portion 116.2 may be laterally displaced, making reliable contact difficult. There is no danger that it will be hindered.

【0016】

As a result, the chip card can be displaced by, for example, 90 degrees from the normal J chip card insertion direction as shown by the arrow P in FIG.

【0017】

The movable direction of the contact 116 is limited to the z direction (FIG. 2), and the corresponding z axis passes through the apex S of the contact portion 116.2, so that it is perpendicular to the surface 112 qo of the contact support 110.

【0018】

In the embodiment of FIG. 9, the contact 116 has a widened portion 116.3 on the opposite side of the adjacent contacts 116.2 and 116.4, but the widening towards the bent middle portion 116.3u. It is getting bigger, and it is constant in the middle part 116.3u.

【0019】

10 and 11 are plan views showing blank shapes during the pressing process according to the prior art. As shown in FIG. 10, the pitch of the adjacent contacts 150a is about 2.5, and the contact portion is punched out in an L shape. Further, as shown in FIG. 11, the adjacent contacts 150b have the same pitch, and the contact portions are formed in a spherical shape on the entire surface.

【0020】

[Problems to be Solved by the Invention]

However, in the contact according to the prior art 1, the contact portion is shaped like a cross or a spoon to provide an invitation to insert the card from the insertion directions 1 and 2, but the contact is manufactured by the pressing process. At that time, if the pitch is equal to the pitch between the SIM card contact parts, the clearance l1 or l2 for removing adjacent objects will be small, and the size of the invitation amount of the invitation part with respect to the card insertion direction 1 will be limited. It had drawbacks.

【0021】

Therefore, one technical object of the present invention is to provide a multi-directional insertion type connector having a contact capable of increasing the clearance for punching in the pressing process even if the magnitude of the invitation amount does not change.

【0022】

Further, another technical problem of the present invention is that by shortening the length of the contact portion of the contact, the dimension in the length direction can be reduced, the contact property can be improved, and the quality can be improved. The purpose is to provide a multi-directional insertion type connector.

【0023】

[Means for solving problems]

According to the present invention, in a connector for inserting a card from at least two directions, a contact provided with a contact portion for connecting to the card and an insulator for holding the contact so that the contact portion of the contact protrudes on one surface. The card is inserted from the first card insertion direction, which is the pitch direction in which the contacts are arranged side by side, and the second card insertion direction, which is orthogonal to the first card insertion direction. The contact portions of the contacts are a first invitation portion that guides the insertion of the card toward the first card insertion direction side and a second invitation portion that guides the card insertion toward the second card insertion direction side. A connector characterized in that each of the first and second invitation portions is formed in a substantially T-shape provided with each other, and at least a part of each of the first and second invitation portions is recessed from one surface of the insulator. Is obtained.

【0024】

Further, according to the present invention, in the connector, a connector is obtained in which a polarity key indicating a card insertion direction is provided on the insulator on the opposite side of the first card insertion direction.

【0029】

Referring to FIGS. 2 (a) to 2 (b), the connector 10 is an insulator made of a trapezoidal insulating material having a square shape and support portions on both lower sides, thereby having a standoff portion 5 recessed upward. It includes 1 and a contact 2 that is held by the insulator 1 and has a T-shaped contact portion 13 that protrudes from the upper surface of the insulator 1. The contacts 2 are mounted on both sides side by side in the length direction, that is, in the vertical direction in FIG. 2 (a). On the side of the insulator 1 opposite to the card insertion direction, a notch (polarity key) 3 indicating polarity is provided to prevent the connector from being mounted in the wrong direction. The insulator 1 has a shape that enables component mounting on the standoff portion.

【0030】

The contact 2 is formed by bending a metal plate having an elongated elasticity into a substantially S shape, and is a contact provided in a round chevron shape on the top for contacting an electric contact portion including a SIM card (not shown). It has a part 13. The contact portion 13 includes a card invitation portion 12 extending diagonally downward from the round apex. The tip of the card invitation portion 12 is bent and extends inward to be rounded. Further, in the width direction of the contact from the apex of the contact portion 13, another card invitation portion 11 extending diagonally downward on the outer side is provided, and together with the card invitation portion 12, a substantially T-shaped contact portion is provided. It constitutes 13.

【0031】

Further, the contact 2 extends diagonally downward inward from the contact portion 13, extends inward from the upper surface of the insulator 1, bends once so as to be parallel to the upper surface of the insulator 1, extends inward, and makes a U-turn so as to draw a U-shape.

【0034】

FIG. 3 is a plan view showing an example of the contact of FIG. 2, and FIG. 4 is a plan view showing another example of the contact of FIG.

【0035】

With reference to FIG. 3, one metal plate of each contact is punched into the blank shape shown in the figure. However, when the pitch P1 of each contact is 2.54, the card invitation portion 11 protrudes to one side and the other 18 is formed small. Since it has a T-shape, the clearance L1 at the time of extraction can be increased.

【0036】

With reference to FIG. 4, similarly, one metal plate of each contact is punched into the blank shape shown in the figure. However, when the pitch P2 of each contact is 2.54, the card invitation portion 11 protrudes to one side and protrudes to the other. Since it forms a T-shape without a part, the clearance L2 at the time of extraction can be increased.

【0037】

Therefore, as shown in FIGS. 3 and 4, the length of the card invitation portion 11 can be doubled or more as compared with that of the prior art.

【0038】

Returning to Fig. 1, by making the contact part of the contact 2 T-shaped, it is not possible to insert the card from the (negative) direction of the card insertion direction 1, but the insulator is provided with a notch indicating polarity and packed. Occasionally, the packing tray or the connector receiving portion of the embossed reel is provided with a convex shape so that the connectors can be physically aligned in the same direction.

【0039】

This makes it possible to mount the connector without aligning the connectors in the wrong direction when mounting the printed circuit board, and it is not necessary to insert the card from the (negative) direction of the card insertion direction 1.

【0040】

From this, in the present invention, it is possible to make the invitation portion with respect to the card insertion direction 1 about twice as large without impairing the characteristics of the prior art and without impairing the productivity.

【0041】

Further, in the contact, a sufficient card invitation portion with high reliability can be formed by increasing the invitation portion 11, and when the SIM card is inserted, the contact contact portion is pressed downward from one side 4 of the insulator. Most of the contact part moves downward and hides.
