Easy to clean connector

This creation is about an easy-to-clean connector, especially a push-pull type connector.

DE 10 2005 057 444 B3 discloses a conventional connector which uses a so-called push-pull latching element, since the connector can be connected by simply plugging the plug body and the slot body into each other, and this push-pull latching member can generally be achieved. The function that is satisfactory is that, in the inserted state, pulling the wire does not cause the connector to be accidentally released, and the connector can be released only after the push-pull latch is released.

However, in the non-plugged state, the conventional connector may be dirty or have other foreign objects running into the open plug connector, resulting in the inability to insert or connect the connector. If the general lock sleeve has no auxiliary means, It cannot be cleaned quickly, so such connectors cannot be used outdoors. Once the existing plug-in system is dirty, it is not necessary to use an auxiliary means to cleanly clean, that is, when the contact diameter is small, the plug-in system cannot even be used or malfunctioned.

The purpose of this creation is to provide an easy-to-clean connector that can alleviate the above-mentioned drawbacks, which can be easily cleaned with a simple structure.

The basic idea of the present invention is that not only the retaining sleeve is movably disposed on the sleeve, but also the sleeve itself can be moved on the plug body so that the sleeve can be moved to the cleaning position in the direction of the wire end. It is convenient to enter the plug end of the plug body.

The sleeve can be pushed back to the desired cleaning position for the purpose of easy access to the plug end of the plug body, so that the contacts on the plug end of the plug body, especially the POGO contacts, can be easily emptied in an extremely simple manner. To carry out the necessary cleaning.

According to the present invention, the spring body can be pushed back against the positioning spring force, and the positioning spring is disposed on the plug body and abuts against the tension reducing sleeve of the sleeve and a ring around the plug body.

By actuating the sleeve, the retaining sleeve can be brought into action so that the sleeve can be moved into the cleaning position by the retaining sleeve.

In the special structure of the present invention, the retaining sleeve can have a plurality of axially extending elastic segments at the end of the wire. When the retaining sleeve is pushed back, the elastic segments can be jammed with the braking member of the sleeve, for example A nut is locked with the nut that is locked to the sleeve, and the sleeve is pushed.

For the purpose of achieving the above-mentioned purpose and effect of the above-mentioned use, a preferred and feasible embodiment will be described, and the details are as follows:

Referring to the first to third figures, a slot body 1 and a plug body 2 are coupled to each other, wherein the slot body 1 is provided with a plurality of POGO contact slots not further shown, the plug body 2 There are a plurality of POGO contacts on the one side that are not further displayed.

The plug body 2 has a clamping sleeve 3 which is axially movable on the sleeve 4. One side of the sleeve 4 is sleeved on the plug body 2.

The sleeve 4 is provided with a plurality of elastic tongues 5 in the axial direction of the plug end thereof, and the like The elastic tongues 5 are elastically sleeved on the periphery of the tank body 1 in the state in which the plug joints are coupled, that is, when the tank body 1 is coupled to the plug body 2 (as shown in the second figure).

The fastening sleeve 3 has a corrugated grip portion adjacent to the wire end, and has a plurality of elastic segments 6 formed by cutting. When the plug body 2 is not coupled, that is, when the locking sleeve 3 is moved to the right. (As shown in the first figure), the elastic segments 6 are jammed with a brake member (such as the nut 7) that is screwed onto the sleeve 4 at the end of the wire.

Further, as shown in the first figure, the plug body 2 is fixed to a tension reducing sleeve 8 at the end of the wire, and a clamping nut 9 similarly for relieving the pulling force is connected to the tension reducing sleeve 8 and a screw lock to reduce the tension. The anti-folding sheath 10 on the sleeve 8.

In order to make the connector reach the coupling state in the second figure, the groove body 1 is inserted into the accommodating space 11 provided through the elastic tongue 5 of the sleeve 4, so that the groove body 1 is sealed with the gasket 12 provided on the front surface. A latch is formed on the front end of the plug body 2, and then the POGO contact of the plug body 2 is inserted into the POGO slot of the slot body 1. Further, the elastic tongue 5 of the sleeve 4 is sleeved on the periphery of the plug body 1. The elastic tongue 5 is extended into the annular groove 13 of the plug body 1 by the end of the front projection.

As shown in the first figure, the fastening sleeve 3 is pushed to the right in the waiting position until the card grips the nut 7, and is inserted into the sleeve by an inner shoulder portion 14 provided on the inner side of the elastic portion 6. The ring groove 15 on the 4, the clamping sleeve 3 is moved forward from the waiting position, that is, to the left as shown in the second figure, until the correspondingly formed ring shoulder of the groove body 1 is caught.

As shown in the second figure, in this position, the fastening sleeve 3 also protrudes into the other annular groove 16 provided on the sleeve 4 by the inner shoulder portion 14 provided on the inner side of the elastic portion 6, whereby the fastening sleeve 3 is fastened. The sleeve 3 is held in a suitable manner, in which position the retaining sleeve 3 radially presses the respective resilient tongues 5 on the sleeve 4 so that the slot 1 is coupled to the plug body 2 and cannot be transferred.

To separate the trough body 1 from the plug body 2, as shown in the second figure, push the retaining sleeve 3 to the right until its elastic section 6 and the nut 7 of the sleeve 4 are jammed, and the inner shoulder is The portion 14 is extended into the ring groove 15, whereby the elastic tongues 5 of the sleeve 4 can be released again in the radial direction, thereby pulling the groove body 1 away from the plug body 2.

The present invention has a special structure, that is, the sleeve 4 is disposed on the plug body 2 and can be moved to the cleaning position in the direction of the wire end, so that the plug end (left end) of the plug body 2 can be vacated, compared with the conventional one. The structure, the structural design can make the POGO contact provided on the plug end of the plug body 2 relatively easy to vacate for necessary cleaning, and for this purpose, the nut 7 of the sleeve 4 is put into the tension reducing sleeve 8 Around the tension member, the tension member formed on the inner circumference of the sleeve 8 is formed on the inner circumference of the sleeve 8. In contrast, the sleeve 1 is moved to the left as shown in the first figure, and is received by the plug side of the plug body 2 Limited by the inner shoulder 18, an inner shoulder portion of the sleeve 4 that is not further labeled creates a click with the inner shoulder portion 18.

The sleeve 4 is affected by the force of a positioning spring 19 provided on the plug body 2, which is biased between the sleeve 4 and the inner shoulder of the tension reducing sleeve 8.

If it is convenient for cleaning, it is hoped that the POGO touch of the plug body 2 can be achieved. Point, the card sleeve 3 is moved from the position in the first figure, that is, its elastic section 6 to the nut 7 of the sleeve 4, and the inner shoulder 14 is snapped into the ring groove 15 to move to the right (as shown in the first figure). As shown, the sleeve 4 will also resist the force of the positioning spring 19 on the plug body 2 as shown in the first figure, moving to the right, up to the inner shoulder 17 of the tension reducing sleeve 8 or until the tension is reduced. The braking portion of the grip portion of the locking sleeve 3 on the front end of the sleeve 8.

As shown in the third figure, in this position, the plug end of the plug body 2 is completely vacant and can be accessed to facilitate cleaning of the POGO contacts herein.

After the movement force for the fastening sleeve 3 is released, the positioning spring 19 will again push the sleeve 4 to the left side, as shown in the first figure, so that the sleeve 4 can again obtain its inner shoulder by the plug body 2. a position limited by 18 (as shown in the first figure), in which the groove body 1 is again coupled to the plug body 2, wherein the design of the elastic tongues 5 on the sleeve 4 is unevenly distributed, The orientation of the plug body 2 relative to the trough body 1 is ensured.
