JPH0592967U - Compression sleeve for trunk branch - Google Patents

Abstract

(57) [Summary] [Structure] On both sides of the branch line connecting portion having a screw hole for connecting the branch line, a compression portion having slits circumferentially provided at a boundary with the branch line connecting portion is provided. , A branching compression sleeve main body in which an electric wire gripping groove is connected to the shaft center and a sleeve collar fitting groove opening to the lower surface is connected, and a compression part provided in the branching compression sleeve body having an electric wire gripping groove on the upper surface is fitted. A pair of sleeve collars that form a main branch compression sleeve. [Effect] Since the slit absorbs the strain generated when compressing the compression part and prevents the slit from reaching the branch line connection part, the branch compression sleeve can be crimped to the main cable conductor without deforming the screw hole. Further, since the sleeve collar fitting groove is opened on the lower surface of the branch line connecting portion, it is possible to effectively prevent the stress due to the extension of the trunk cable conductor from being applied to the branch compression sleeve. Furthermore, the exposed length of the main cable conductor can be shortened.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a trunk sleeve compression sleeve.

[0002]

[Prior Art]

 As shown in FIG. 8, the conventional trunk branch sleeve has a U-shaped groove 21 formed in the sleeve 20 and the trunk cable conductor C which is exposed by peeling off the branch line attachment position from above. , The lid 23 is attached to the U-shaped groove 21, the sleeve 20 is attached to the main cable conductor C by soldering, and the pin contact (not shown) of the connector attached to the branch line is screwed to the screw hole 22. Was configured into.

[0003]

[Problems to be solved by the device]

 However, if the branching sleeve 20 is attached to the main cable conductor C by soldering, it is difficult to judge whether or not it is completely attached, and not only reliability is lacked, but the soldering work is performed from the lower side of the branching sleeve 20. Therefore, the workability is extremely poor, and when the lid 23 is attached to the U-shaped groove 21, the exposed length of the main cable conductor C must be increased because the lid 23 is long. was there.

It is possible to crimp the branching sleeve 20 to the main cable conductor C by compression instead of soldering work. However, when the branching sleeve 20 is crimped to the main cable conductor C by compression, There is a problem that the screw hole 22 is deformed due to the distortion, and it becomes impossible to screw the pin contact or the like of the connector attached to the branch line.

The present invention has been made in view of the above problems, and can completely and firmly crimp the main cable conductor without deforming the screw hole, and can shorten the exposed length of the main cable conductor. An object is to provide a compression sleeve for bifurcation.

[0006]

[Means for Solving the Problems]

 According to the present invention, a compression part 4 is provided on both sides of a branch line connecting part 2 having a screw hole 3 for connecting a branch line, and a slit 5 is formed in a circumferential direction at a boundary with the branch line connecting part 2. , A branching compression sleeve body 1 in which an electric wire gripping groove 6 and a sleeve collar fitting groove 7 opening to the lower surface are connected in series at the axis, and the electric wire gripping groove 6 provided in the branching compression sleeve body 1 faces each other. The main line branching compression sleeve is constituted by a pair of sleeve collars 8 provided on the upper surface with electric wire gripping grooves 9 and fitted into the compression portion 4 of the branching compression sleeve body 1, thereby eliminating the conventional problems.

[0007]

[Action]

 A pin contact or the like of a connector attached to the branch line is screwed into a screw hole 3 formed in the branch line connection portion 2 of the branch compression sleeve body 1. A sleeve collar 8 is fitted to the compression portions 4 provided on both sides of the branch line connecting portion 2, and the compression portion 4 is compressed with the sleeve collar 8 fitted to the compression portion 4, and a compression sleeve body for branching is provided. 1 is crimped to the main cable conductor C. The slit 5 formed in the circumferential direction of the boundary between the branch line connecting part 2 and the compression part 4 and the sleeve collar fitting groove 7 opening on the lower surface of the branch line connecting part 2 connect the branching compression sleeve body 1 to the main cable. The screw hole 3 formed in the branch line connecting portion 2 is prevented from being deformed due to the strain when the conductor C is crimped, and the stress due to the extension of the cable is effectively prevented from being applied to the branch compression sleeve body 1. To do.

 Embodiments of the present invention will be described below with reference to the drawings. 1 is an exploded perspective view showing an embodiment of the present invention, FIG. 2 is a top view, FIG. 3 is a side view, FIG. 4 is a sectional view taken along line XX of FIG. 2, and 1 is a branch compression sleeve body. Reference numeral 2 is a branch line connecting portion, and the upper surface of the branch line connecting portion 2 is formed smooth and has a screw hole 3 formed therein. A pin contact (not shown) of a connector attached to the branch line is screwed into the screw hole 3. 4, 4 are compression parts provided on both sides of the branch line connecting part 2, 5 are slits formed in the circumferential direction of the boundary between the branch line connecting part 2 and the compression parts 4, 4, and 6 and 7 are A semi-circular electric wire grip groove formed in the axial center of the branch compression sleeve body 1 and a T-shaped sleeve collar fitting groove that is continuous with the electric wire grip groove 6 and opens on the lower surface. Reference numerals 8 and 8 denote a pair of T-shaped sleeve collars, and the upper surfaces of the sleeve collars 8 and 8 face a semicircular electric wire gripping groove 6 bored at the axis of the branch compression sleeve body 1. A semicircular electric wire gripping groove 9 is provided. The sleeve collars 8 and 8 are fitted into the compression portions 4 and 4 provided on the branch compression sleeve body 1, respectively.

The shape of the sleeve collar 8 and the shape of the sleeve collar fitting groove 7 can be appropriately designed and changed.

In order to crimp the branch compression sleeve of the present invention configured as described above to the trunk cable conductor, the branch cable attachment position is stripped to expose the trunk cable conductor C as shown in FIG. The branch compression sleeve body 1 is fitted from above. Next, the three sleeve collars 8 and 8 are fitted into the sleeve collar fitting grooves 7 formed in the branch compression sleeve body 1 and arranged at the positions of the compression portions 4 and 4, respectively, and as shown in FIG. The compression portions 4 and 4 to which the collars 8 and 8 are fitted are compressed using the compression jig A, and the branch compression sleeve body 1 is crimped to the main cable conductor C as shown in FIG.

Strains generated when the compression portions 4 and 4 are compressed are absorbed by the slits 5 and 5 provided in the circumferential direction of the boundary between the compression portions 4 and 4 and the branch line connecting portion 2. Since it does not reach the branch line connecting portion 2, the branch compression sleeve body 1 is completely and firmly crimped onto the main cable conductor C without deforming the screw hole 3 formed in the branch line connecting portion 2. can do. Further, as shown in FIG. 7, the sleeve color fitting groove 7 is largely opened on the lower surface of the branch line connecting portion 2, so that the stress at the time of compression can be effectively prevented from acting on the branch line connecting portion 2. . Furthermore, since the length of the compression portion 4 is short, the exposed length of the main cable conductor C can be shortened.
