Bipartite multi-tap compression according to each embodiment of the present invention shown in the drawings. -The connector is configured to hold at least one main wire and at least two tap wires. 1 to 6 are views showing the compression connector 20, FIGS. 7 to 12 are views showing the compression connector 120, and FIGS. 13 to 19 are views showing the compression connector 220. ..

The two-split multi-tap compression connector 20 shown in FIG. 1 shows a state in which the caulking work is completed and the connector is fixed to the main wire 22 and the tap wires 24 and 26. The compression connector 20 is preferably a one-piece component made of a conductive material such as copper. However, the compression connector 20 can be made of other suitable materials as long as it can be crimped, and can also have a structure in which a plurality of suitable members are joined.

As shown in FIGS. 2 and 4, the compression connector 20 includes a first section 28 and a second section 30. As is clear from FIG. 3, the first section 28 includes the first body portion 32. The hook portion 34 and the slope image forming protrusion 36 extend from the first body portion 32 to define a main wire insertion port 38 through which the main wire 22 can be inserted and loaded. The shape of the hook portion 34 is preferably C-shaped. The first section 28 further comprises a first end wall 40 connected to a first body 32. Two tap wire insertion ports 42 and 44 are formed adjacent to the first end wall portion 40, and two holding protrusion portions 46 and 48 extend diagonally from the first body portion 32. There is. A groove 50 is formed between the holding protrusion 46 and the slope drawing protrusion 36, and a groove 52 is formed between the holding protrusion 48 and the hook 34. The first body portion 32 and the first end wall portion 40 are connected by a link portion 53 that is easily plastically deformed, and this link portion 53 is defined between the two tap wire insertion ports 42 and 44. ing.

The provision of retaining protrusions 46, 48 improves the overall compressibility of the compression connector 20, because the provision of them improves the tap wire insertion ports 42, 44 in various sizes. This is because it can be used for tap wires 24 and 26. As shown in FIG. 6, the tap wire insertion ports 42 and 44 are designed to accommodate the thick tap wire 24 and the thin tap wire 26. By providing the holding protrusion 46, the gap between the first end wall 40 and the first body 32 is reduced, which allows tap wire insertion before and during the caulking operation. The positioning accuracy and fixed holding force of the tap wire 24 in the port 42 are enhanced. Similarly, by providing the holding protrusion 48, the gap between the first end wall 40 and the first body 32 is reduced, thereby tapping before and during the caulking operation. -The positioning accuracy and fixed holding force of the tap wire 26 in the wire insertion port 44 are enhanced. The shape of the tap wire insertion ports 42 and 44 is preferably a teardrop shape. As is clear from FIG. 3, the tap wire insertion port 42 is formed larger than the tap wire insertion port 44. However, as shown in FIG. 8, the two tap wire insertion ports 42 and 44 may be formed to have substantially the same size.

The second section 30 has the same configuration as the first section 28. As is clear from FIG. 5, the second section 30 includes a second body portion 54. A hook portion 56 and a slope drawing protrusion 58 extend from the second body portion 54 to define a main wire insertion port 60 through which the main wire 22 can be inserted and loaded. The shape of the hook portion 56 is preferably C-shaped. The second section 30 further comprises a second end wall portion 62 connected to the second body portion 54. Two tap wire insertion ports 64 and 66 are formed adjacent to the second end wall portion 62, and two holding protrusion portions 68 and 70 extend diagonally from the second body portion 54. There is. A groove 72 is formed between the holding protrusion 68 and the slope drawing protrusion 58, and a groove 74 is formed between the holding protrusion 70 and the hook 56. 2nd Bo The di portion 54 and the second end wall portion 62 are connected by a link portion 75 that is easily plastically deformed, and this link portion 75 is defined between the two tap wire insertion ports 64 and 66. .. Further, as shown in FIGS. 1, 2, and 4, the first body portion 32 and the second body portion 54 are connected by the central body portion 76.

As is clear from FIG. 4, the compression connector 20 includes two slots 78 and 80, which are formed by cutting into the compression connector 20. Slots 78 and 80 are wrapped with cable ties (not shown) for fastening and holding the main wire 22 and tap wires 24 and 26 to the compression connector 20 prior to performing the caulking operation. At the time, it provides a space for inserting the cable tie. This is disclosed in U.S. Patent Application No. (Application Agent Reference Number: LCB394), which is a co-pending application of the corresponding U.S. application of the present application, and the disclosure of the U.S. patent application is the entire disclosure of this U.S. patent application. Is incorporated into the disclosure of the present application. Thus, the compression connector 20 shown in FIGS. 1 to 6 has slots 78 and 80, but the compression connector 20 has been modified so that it does not have such a slot. It can also be an embodiment.

7 to 12 show a second embodiment of the present invention. As shown in FIG. 7, the two-split multi-tap compression connector 120 according to this embodiment has substantially the same structure as the compression connector 20 shown in FIGS. 1 to 6, and is located between the two. The difference is that in the compression connector 120, the two tap wire insertion ports are formed to be approximately the same size, otherwise there is no major difference. Although there are differences, the compression connector 120 is basically the same as the compression connector 20 shown in FIGS. 1 to 6.

Explaining how to use it, since the compression connector 20 is C-shaped, there is almost no need to support the compression connector 20 by hand when installing it, because the hooks 34 and 56 are the main parts. This is because the tap wire 24 can be inserted into the tap wire insertion ports 42 and 64 and the tap wire 26 can be inserted into the tap wire insertion ports 44 and 66 while being hooked on the wire 22. .. When using the compression connector 20, a wire must be inserted through at least one of the main wire insertion port 38 and the two tap wire insertion ports 42 and 44. Only the remaining one tap wire insertion port 42 or 44 may be wire inserted or left empty without insertion. Similarly, a wire must be inserted through the main wire insertion port 60 and at least one of the two tap wire insertion ports 64, 66. Only the remaining one tap wire insertion port 42 or 44 may be wire inserted or left empty without insertion. The compression connector 20 can crimp both the first section 28 and the second section 30 with a single caulking operation.

When performing the caulking work on the compression connector 20, for example, Panduit Use a crimping tool (not shown) such as the CT-2940 crimp tool with a pair of crimp dies (not shown) such as the Panduit CD-940H-250 crimp die. Just do it. The outer peripheral radii of the hooks 34 and 56, and the outer peripheral radii of the first end wall 40 and the second end wall 42 are smaller than the inner radius of the crimp die, so what is a crimp die? Make contact at two contact points. Then, by performing the caulking operation, as is clear from FIGS. 6 and 10 to 12, the hook portions 34 and 56 are curled up to embrace the wire 22, thereby providing electrical performance and mechanical performance. A connected state with excellent performance can be obtained.

13 to 19 show a third embodiment of the present invention. The bipartite multi-tap compression connector 220 shown in FIG. 13 has been crimped and secured to the two main wires 222, 224 and the two tap wires 226, 228. It shows the state. The compression connector 220 is preferably a one-piece component made of a conductive material such as copper. However, the compression connector 220 can be made of other suitable materials as long as it can be crimped, and can also have a structure in which a plurality of suitable members are joined.

As shown in FIG. 14, the compression connector 220 includes a first section 230 and a second section 232. The first section 230 comprises a first body portion 234. The hook portions 236 and 238 and the slope drawing protrusions 240 and 242 extend from the first body portion 234, and as shown in FIG. 18, the main wires 222 and 224 can be inserted and loaded. It defines the main wire insertion ports 244 and 246. The shape of the hook portions 236 and 238 is preferably C-shaped. As is clear from FIG. 18, since the compression connector 220 is S-shaped, there is almost no need to support the compression connector 220 by hand when installing the compression connector 220, because the hook portions 236 and 238 are used. This is because the tap wires 226 and 228 can be inserted into the side tap wire insertion ports 248 and 250 while being hooked on the main wires 222 and 224. As shown in FIGS. 17 to 19, the side tap wire insertion ports 248 and 250 are not on the same horizontal plane, but have different heights, so that they are between the insertion ports 248 and 250. A columnar region that is easily plastically deformed and extends diagonally is defined in the area. The outer peripheral radii of the hooks 236 and 238 are smaller than the inner radius of the crimp die (not shown), so that they come into contact with the crimp die at two contact points 252 and 254. Then, by performing the caulking work, as is clear from FIG. 19, the hook portions 236 and 238 are curled up to hold the main wires 222 and 224, and the outside of the hook portions 240 and 242 is further covered with the slope painting protrusions 240 and 242. Will be covered. Further, as shown in FIG. 19, since the above-mentioned diagonally extending columnar region portion is easily plastically deformed, the side tap wire insertion ports 248 and 250 are deformed so as to be crushed, thereby causing the side tap wire insertion ports 248 and 250 to be deformed. Tap wires 226 and 228 are fixedly held in the insertion ports 248 and 250.

The second section 232 also has the same configuration as the first section 230. The second section 232 includes a second body portion 256. The hook portions 258 and 260 and the slope drawing protrusions 262 and 264 extend from the second body portion 256, and the main wire insertion ports 266 and 268 can be inserted and loaded through the main wires 222 and 224. Is defined. The shape of the hook portions 258 and 260 is preferably C-shaped. Since the compression connector 220 is S-shaped, there is almost no need to support the compression connector 220 by hand when installing it, because the hooks 258 and 260 are pulled to the main wires 222 and 224. This is because the tap wires 226 and 228 can be inserted into the side tap wire insertion ports 270 and 272 in the hooked state. The outer peripheral radii of the hooks 258 and 260 are smaller than the inner radius of the crimp die, so that they come into contact with the crimp die at two contact points 274 and 276. Further, as shown in FIGS. 14 and 16, the first body portion 234 and the second body portion 256 are connected by the central body portion 278.

According to the two-split multi-tap compression connector provided by the embodiment of the present invention disclosed above, the fixing holding force of the tap wire before and during the caulking operation is enhanced.
