Problems solved by technology

[0009] In the above-mentioned conventional examples 2 and 3, although the wire 5 can be pressed into the crimping groove 24a without loosening the twist even if it is a tightly twisted wire, the four tapered surfaces 23r, 23s, Each junction B of 23t and 23u is angular, so that four places of the insulating sheath of the electric wire 5 connected to the junction B11, B12 in FIG. 22 and the junction B13 in FIG. 25 are under pressure and may be damaged (see Figure 26 place E) rupture

Embodiment 1

[0047] Hereinafter, the combined socket of this embodiment is demonstrated with reference to FIG. 1 and FIG. 2, and the same code|symbol is attached|subjected to the same component as a conventional example, and it demonstrates.

[0048] The combined socket of the present embodiment is provided with: the shell 1 that the opening has the plug insertion port 11a that inserts the combined plug; 8) linear terminals 13 (refer to FIG. 3); a plurality of (in this embodiment, 8) terminal blocks 24 (refer to FIG. ) and the junction box 2 combined with the shell 1.

[0049] The case 1 is made of insulating synthetic resin, and includes a rectangular parallelepiped connection base 11 , and the plug insertion opening 11 a is opened on one side of the connection base 11 . Hereinafter, the up-down direction is defined by the up-down direction in FIG. 1 with the side of the connection table 11 having the plug insertion port 11a opened as the front. A base 12 for connecting the junction box...

Embodiment 2

[0061] The modular socket of this embodiment is a modular socket in which the vicinity of the upper end of the protective wall 23a is formed into a so-called eyelid shape. Here, as shown in Figure 9 (a) (b) (c), the so-called eyelid shape refers to that when the twisted portion 5a is inserted, the vicinity of the upper end of the protective wall 23a that the electric wire 5 contacts is made from the connection length direction ( The ridge line 23e between the middle and the upper end 23c of both ends of the wire arrangement direction) is inclined toward the lower side wall 23j and forms a curved tapered surface 23d along the circumferential direction. And the ridge line 23e forms the upper end 23c in the approximate middle part. Then, as shown in FIG. 10, if the upper end 23c of the protective wall 23a is inserted into the twisted portion 5a (dotted line A1) and the twisted portion 5a touches the tapered surface 23d of the protective wall 23a, since there is no corner at the p...

Embodiment 3

[0063] As shown in FIG. 11, the combined socket of this embodiment is a combined socket in which the vicinity of the upper end of the protective wall 23a is made into a three-sided cone shape shown in FIG. 12 (a), (b), and (c). Here, the so-called three-sided cone shape means that when the twisted part 5a is inserted, the vicinity of the upper end of the protective wall 23a that the electric wire 5 contacts is made into three tapered surfaces 23f that are gradually tapered from the side wall 23j to the upper end 23c and inclined. , 23g, 23h constitute the tapered surface, compared with the conventional example of the 4-sided cone shape, the mutual interface portion B of the tapered surface is reduced. Especially in this embodiment, the upper end 23c of the protective wall 23a is deviated to one end of the longitudinal direction of the protective wall 23a. As shown in FIG. A1), there are two places at the junction B1 of the tapered surfaces 23f, 23g, and 23h that the electric w...

Abstract

Provided is a modular jack not burdening local load on a stranded wire to be connected to a pressing slit, hardly damaging an insulation coating of the wire. A plurality of protection walls 23 of which a length of a part protruded from an upper surface is larger than that of terminal plates 24 are arranged in protrusion in a back and forth direction at left and right sides at the upper surface of a terminal stand 2 jointed to a housing 1, and the terminal plates 24 are located so as to make pressing slits 24a corresponded between the protection walls 23 standing adjacent back and forth to each other. Out of the protection walls 23, an upper part of a protection wall 23a standing between the two terminal plates 24, 24, to which a pair of wires 5, 5 are to be connected, is formed into a shape of almost flat elliptical cone-shaped surface basing on an ellipse. Respective wires 5 are guided into and press fitted to the pressing slit 24a by inserting the protection wall 23a between stranded wires (twisted part) of the wires 5, 5.

Description

technical field [0001] The present invention relates to a combined socket having a terminal board provided with crimping grooves, and electric wires which are insulated sheathed wires are pressed into the crimping grooves of the terminal board for connection. Background technique [0002] Hitherto, modular sockets have been used for connecting communication cables to each other or to other devices. On the other hand, the modular socket has a housing provided with a plug insertion opening into which the modular plug can be detachably inserted, and terminals are arranged in the housing through the plug insertion opening to be in contact with the joint of the modular plug inserted into the housing. In addition, a junction box for connecting to an electric wire such as a twisted pair of insulated sheathed electric wires is connected to the case, and the terminal is electrically connected to the terminal block of the junction box. As a terminal board, it is made into a two-prong...
