When the protector 2 is inserted into the protector insertion terminals 6 and 7 in the finished wiring, one line is formed.

As such, there are six contact element points between the existing protection-based socket (FIG. 1) terminal and the cable.

However, since the IDC terminal structure of the protection-based 10 pairs of the protector insertion terminals 6 and 7 is separated from the IDC terminal, it is difficult to wire the lead-in and pull-out cables and the contact element loss is large with respect to the electrical performance.

Accordingly, the present invention has been made to solve the above-mentioned conventional problems, and the proposed protection-based 10-pair IDC terminal is a communication equipment for protecting subscribers from overvoltage overcurrent. The aim is to provide a protection base with 10-pair IDC terminals, which facilitates wiring and improves electrical performance, greatly improving contact element losses.

As shown in FIG. 5, polarities are distinguished with respect to five housings 12 in which the inlet cable 1 is guided to a predetermined base 11, and the lower end of the housing 12 is moved from the upper direction to the lower end of the base 11. After assembling in the assembly, the five housings 13 through which the lead-out cable 4 exits are integrally assembled in the same manner to complete the housing assembly.

Subsequently, 20 signal contact elements (SIGNAL CONTACT) 9 connected with the inlet cable 1 to the base 11 of the housing are divided in assembling directions so that the upper end of the signal contact element 9 is directed toward the lower end of the base 11. It is assembled from the downward direction of the base 11 to the upward direction so as to be assembled. Thereafter, the signal contact element 10, which is the contact element of the lead-out cable 4, is also assembled in the same manner as in the previous method.

FIG. 6 is a perspective view of an integrated signal contact device terminal for the protection-based 10 pair of FIG. 5.

The contact element beam 19 in contact with the protector insertion terminal 21 is composed of three. One contact element beam 19 is constructed at an angle of 120 ° to improve durability and contact reliability of the contact element. Since the protector insertion terminal 21 is circular, the contact element is also circular. In addition, since the contact element beading 20 is formed in the protector insertion terminal 21 to improve the reliability of the contact element, the contact element is easily inserted when the protector 21 is inserted. To be mounted.

A protector insertion terminal 21 is inserted into each of the inlet and outlet holes of the base 11, which is a body. The connecting part 22 serves to guide the contact element to be coupled to the center of the hole of the base 11, and when the contact element is inserted into the base 11, if the catching jaw 23 is not present, the protector 2 is inserted after extraction. Flow occurs at the terminals. This causes instability of the contact element and deformation of the terminal. The rake 24 is formed to prevent flow and maintain and fix the terminal strength of the protector insertion terminal 21. Rake 24, when assembled to base 11, withstands forces of at least 5 kgf.

The connecting beam 25 serves to electrically connect the protector insertion terminal 21 and the IDC terminal 28 to which the cable is connected integrally, and its material is made of phosphor bronze. And the connecting beam 25 is also coupled to the base 11 is mounted to the guide grooves to also function to withstand flow prevention and withstand voltage.

The IDC terminal 28 directly connects the incoming and outgoing cables, and the guide groove 30 functions to guide the 0.4mm to 0.65mm cable easily and to facilitate the cable stripping.

The contact element (signal contact element) inserted into the base 11 and the housings 12 and 13 is operated by a dedicated tool when connecting the cable, wherein the housings 12 and 13 are 0.4 mm in contact element deformation and 0.4 mm. To 0.65 mm cable, and the cable is retained in the V-shaped groove 29 that protects the contact element. Restoration groove 31 makes the resistance change of the contact element extremely minute and durable against repeated insertion or extraction of the contact element.

The configuration of the contact preventing V-shaped groove portion 29 and the restoration groove 31 can be determined according to the selection and size of the material, of course.

Like the locking jaw 23 of FIG. 6, the locking jaw 26 is a rake that maintains the position of the contact element uniformly without flow when the IDC terminal 28 is separated after the cable connection. 27) is assembled to the base 11 to prevent pin deformation and flow.

By developing different contact element objects as integrated contact elements 9 and 10 in order to improve contact element reliability as described above, product manufacturing is reduced and the function of protection-based 10 pairs is satisfied while satisfying contact element reliability and contact element durability. It will play a decisive role. As a result, the contact element (signal contact element) constitutes the IDC terminal 28 and the protector insertion terminal 21 in one piece, thereby eliminating contact element loss and contact element instability with respect to cable use.

According to the protection base having the 10 pair IDC terminal of the present invention as described above, the IDC terminal structure of the protection base 10 pair (FIG. 3) integrates the protector insertion terminal 21 and the IDC terminal 28 as shown in FIG. By configuring the cable arrangement of the lead and draw as shown in Figure 4, the wiring is easy and the electrical performance is improved to greatly improve the contact element loss.
