Combined socket

Abstract

PROBLEM TO BE SOLVED: To provide a modular jack in which a wire connecting work can be carried out without using an exclusive tool such as an impact tool and a tool such as a pair of pliers, and furthermore in which poor termination of an electric wire is hard to occur. SOLUTION: This jack is provided with a plurality of contacts 13 which are arranged in a plug insertion port 11a in a housing 1 and which are capable of contacting with a contact point of the modular plug, a terminal board 2 connected to the housing 1, and a protective cap 3 removable from the terminal board 2. In the terminal board 2, a terminal plate is arranged so that a crimping slit will correspond to between respective pairs of protective bulkheads 23 adjacent in the insertion direction of the modular plug. In such a state that the protective cap 3 has been removed from the terminal board 2, a simple tool part 35 in which one electric wire 5 is pushed into the crimping slit of the terminal plate selected alternatively among a plurality of terminal plates, and connected electrically is protrudingly installed at the protective cap 3.

Description

Technical field [0001] The present invention relates to a terminal block provided with a crimping groove, and a modular receptacle in which an electric wire of an insulated covered wire is pressed into the crimping groove of the terminal block to be connected. Background technique [0002] Up to now, as a cable for information and communication, a double-button cable containing several pairs of double-button wires armored and retracted has been widely used, and a modular socket equipped with a junction box for connecting the double-button cable has been provided. As such a junction box, a junction box provided with a junction board having a crimp groove is known. The terminal block is made into a two-tooth fork shape with an open crimping groove at one periphery. If the wires constituting the double-button cable are pressed into the crimping groove, the insulation covering of the wire is cut off at the periphery of the crimping groove, and the core wire It is crimped on the perip...

Problems solved by technology

[0010] However, having Figure 19 as well as Figure 20 In the combined socket with 2 protective covers 3" shown, there is a disadvantage that the 2 protective covers 3" are easily lost after being removed from the junction box 2

in addition, Figure 19 as well as Figure 20 The protective cover 3" shown has the problem that the surface area to be pressed is small and difficult to press, and the unbalanced pressure applied to the four wires 5 is likely to cause poor contact at the front end and lead to poor contact.

[0011] On the other hand, having Figure 21 as well as Figure 22 In the combined socket with the protective cover 3' shown, since only one protective cover 3' can be used, the protective cover 3' is not easily lost, and there is sufficient space when the protective cover 3' is pressed with the thumb. During the wiring operation, because the used electric wires 5 of the double-button cable 4 must be pressed into the crimping grooves 24a of 8 terminal blocks 24 at the same time, it is different from that in use. Figure 19 as well as Figure 20 The force (approximately 5kgf) required in the case of the two protective covers 3” shown will require a larger force (above 10kgf), and special tools such as pliers are required.

Pliers are not a tool that is generally carried, and cannot meet the needs of construction workers who want to reduce the number of tools they carry

In addition, there is a problem that the unbalanced pressure applied to the eight electric wires 5 may easily lead to poor contact at the front end.
