The present invention is a telephone station where the line is installed to the terminal box of the building, and when connecting the telephone line of the office or the like from the terminal box, the wire is selectively inserted into the hole of the wire holder without removing the outer shell of the wire, The present invention relates to a telephone line branch terminal wire fixing connection designed to allow the inner copper wire to be firmly connected to a wire clip as a conductor as the outer shell is cut.

In general, the telephone line from the telephone company to the telephone is mostly connected to the branch terminal fixed to the building or other place around the user through the main cable, and wired to the internal and external terminal jacks. By connecting two wires, the user's telephone in each home, office, and shop is wired.

At this time, the method of connecting the wire wire connected to the branch terminal and the telephone line through each main cable is normally connected only when several wires of the main cable are connected to the connecting rods arranged at both sides of the branch terminal. Strip a relatively large number of wires by peeling off the outer skin of each wire wire, dismantling the bolts assembled on the inside of the connecting rod, winding a part of copper wire on the outside of the bolt, and screwing the connecting rod again. Is connected and fixed, and the wire for wiring to the telephone of each user along the telephone station number is stripped of the outer shell of the connecting rod, and the copper wire is wound around the bolt and screwed to the connecting rod of the branch terminal. Wires from the main cable to the telephone and from the telephone Branch was able to connect the terminal.

This relatively primitive connection work delays a lot of work time and is inefficient, and requires many workers. Therefore, it is inexpensive. In addition, it was necessary to repeat the process of unwinding and rewinding the wound copper wire, which caused many inconveniences during repair work, and after the work, many copper wires and parts of the shell were scattered around to harm the surrounding environment or material loss. There was an issue.

Therefore, Utility Model Registration No. 52293 (August 90, 1990-7119), to which the present invention has been filed in advance, registered a plurality of trunk lines connected through a main cable as shown in FIG. It is provided in the wire clip 33 coupled to the main body through a security plug to block the cut off, cut off a plurality of branch holes on both sides of the main body, a wire clip 33 is formed in the assembly hole of the diaphragm, the wire holder A rectangular guide hole 37 is vertically cut in the center portion of the 35 to allow the wire clip 33 to move up and down, and the intermittent section 38 is intermittent to a fixing bar that is fixed inside the single wire 35 of the screw wire. When the branch line D is inserted into the leading hole 36 and descends, the outer surface of the branch line D is cut by the guide inclined surface 33a and the cover cut portion 33b of the wire clip 33, and the copper D ' ) Is positioned at the lower end of the gripping hole 33c. The locking jaw 39 of the liver 38 is caught on the bottom of the fixing bar of the body, and when the wire holder 35 is separated, the protrusion piece 40 protruding from one side of the bottom of the liver is caught by the protrusion of the fixing bar. It was structured to prevent that, and it was possible to wire without peeling off the outer shell of an electric wire.

However, in this configuration, only one inlet 36 is formed in the wire holder 35, and only one clamping hole 33c is formed in the wire clip 33 corresponding thereto. In addition to the problem that only the wire of the use, the depth of the inlet hole 36 is short, there is a fear that the branch line (D) is cut when moving up and down, left and right, as well as the wire clip 35 between the diaphragm of the body If the flow is installed to be used several times, the gap between the narrowing hole (33c) is widened, there was a problem such that the branch line (D) easily falls out.

In order to solve such a conventional problem, the present applicant has filed an application for improvement of utility model registration No. 6,453 on 1991. 5. The branch terminal of the improved application telephone line protrudes on one side of the wire holder 4. The guide protrusion 6 is provided with a plurality of wire entry holes 6a, 6b, 6c having different diameters, and the wire clip 3 has a plurality of stages corresponding to the wire entry holes 6a, 6b, 6c. The pinholes 8a, 8b, and 8c are formed, but the upper width of the wire clip is formed to match the width of the gap formed between the diaphragms of the main body, so that when the branch line is connected to the telephone line branch terminal, Not only can it be connected to the thickness, but also the length of the branch line inserted into the inlet hole is longer than before, so even if the branch line moves up, down, left, and right, there is little risk of cutting, and the wire clip is tightly inserted between the diaphragms. Since the interval between the pincers does not open even after long-term use, the branch line of the telephone line has been selected in advance to prevent the branch line from escaping from the pincers. In order to prevent the wire holder from being pulled out in the configuration, there is a problem that the size of the terminal body is large because the area for the coupling portion of the wire holder and the wire holder is increased.

When the terminal body becomes large, it takes up a lot of peripheral space during the rise and installation of the manufacturing cost, there was a problem that is not easy to handle.

In particular, only one wire can be inserted into a wire holder and a clip to connect a telephone line to a conventional branch terminal, and two wires are used to connect and fix a pair of telephone line wires to a split branch terminal. Increasing the number of parts due to the need for more straighteners and wire clips has contributed to the ease of wiring and the difficulty of assembly and handling.

Therefore, in the telephone line branch terminal, a configuration capable of easily connecting and fixing a pair of two-wires while forming a terminal body with a minimum area is required.

In addition, it is required that the wire holder is stably fixed without shaking in a state in which the wire holder is coupled to the branch terminal body, and the wire fixing is required by the structure formed on the holder itself, and the wire holder is easy to handle by the structure formed on the holder itself. When the outer skin of the wire is cut off, the wire clip forming the connection of the conductor is required to achieve a stable coupling state assembled in the telephone line branch terminal.

Therefore, the present invention can increase the functions of the wire holder and the wire clip assembled to the telephone line branch terminal, and at the same time can minimize the installation area of the wire clip and the holder, and will be described in detail with the accompanying drawings. Is as follows.

The wire fixing chamber 12 formed in the telephone line branch terminal 11 is partitioned at one side so that the wire clip 22 is inserted into the wire fixing chamber 12 and fixed thereto, and the wire holder 20 through which the telephone wire wire 20 is penetrated. In the case where the wire clip 22 is fitted into and fixed to the wire clip 22, the wire crepe 22 can be fitted at both centers of the partition 13 forming the wire fixing chamber 12 of the telephone line branch terminal 11. A support 14 is formed to vertically form the insertion groove 15, and the insertion hole 16 is formed at the bottom of the wire fixing chamber 12, and the locking step 17 is formed at the bottom of the insertion hole 16. To form.

The cut wire 221 of the wire and the wire connecting groover clip 22 are formed on the top of the wire crepe 22 inserted into the insertion groove 15 and the insertion hole 16, and the wire crepe 22 is formed. The lower end forms a fixing piece 223.

The fixing piece 223 extends the lower end of the wire creep 22 to be folded at an appropriate place, and the inclined jaw 224 at the end thereof contacts the wire creep 22 surface.

The wire holder 21 having a width inserted into the wire fixing chamber 12 of the wire branch terminal 11 is dug a square groove at the top to excavate the handle groove 211 and a pin hole 212 in the center thereof. It is formed, and cut into the thickness and height of the partition wall from the bottom to the bottom of the wire holder to form a partition groove (213), and the wire insertion hole 214 is formed on the front surface of the wire.

The bottom surface of the wire holder 21 is formed by digging out the wire creep groove 216, and the wire creep groove 216 is dug from the bottom to the height of the partition wall 13.

At this time, since the front end of the creep is dug in the center of the creep, the wire support 217 that can be inserted into the front end of the creep is formed on the upper surface of the wire creep groove 216 to be left in the v shape.

The V-shaped wire support 217 is a very specific part of the present invention, and when the wire is inserted into the creep, the wire is supported by the connection hole 222 of the creep. It extends from the connection hole creep 22, which serves to prevent breakage due to repeated bending of the very thin telephone line wire.

Then, both sides of the wire creep groove 216 around the partition groove are formed by digging the support groove 218 sliding along the outer surface of the support 14 of the partition to surround the support 14.

The present invention having such a configuration starts by inserting the wire 20 into the wire insertion hole 214 of the wire holder 21 as in a conventional telephone line wire connection job.

A wire crepe 22 is already sandwiched between the supports 14 of the wire fixing chamber 12 of the telephone line branch terminal 11 to which the wire holder 21 is assembled, and the inclined jaw 224 of the folded end is Engaged in the locking step 17 of the bottom of the insertion hole 16 of the branch terminal 11 to achieve a stable fixed state.

When the wire holder 21 is inserted into the wire fixing chamber 12, the wire creep groove 216 is fitted to the support 14 and the wire crepe 22 protruding from the partition wall 13.

Therefore, the wire 20 inserted into the wire insertion hole 214 is cut off the coating of the wire by the cut surface 221 of the creep, thereby making the connection of the insertion door conductors to the wire connection hole 222.

When the wire 20 is inserted into the connection hole 222 of the creep as described above, because the width of the connection piece 222 is narrow, the bending phenomenon occurs in the wire 20, but the V-shaped support part 217 of the wire holder 21 is formed. Since the tip is in contact with the upper surface of the wire 20 before and after the connection hole 222, and the wire holder 21 is inserted into the wire fixing chamber 12 in this state, a phenomenon occurs that the wire 20 is inserted in the process of bending. You will not.

At this time, although the connection hole 222 of the wire creep 22 is slightly opened due to the thickness of the wire 20 is inserted, the size of the wire holder 21 and the fixing chamber 12 is the same, the creep groove 216 Since support grooves 218 are formed on both sides of the support 14 to surround the support 14, the wire clips are not opened in the assembled state of the fixing chamber 12 and the wire holder 21, and both sides of the wire 20 of the telephone line are opened. Tightening is performed, and when both sides of the wire creep are tightened, the contact force between the wire and the creep is increased, and the fixing chamber of the branch terminal 11 is inserted by inserting two wires 20 into the wire holder 21. When the wire holder 21 is inserted into 12, two wires 20 are connected to the wire crepe 22 at the same time, thereby significantly reducing the amount of work and working time when working with multiple strands, and the wire holder. (21) The handle groove 211 is formed in itself, the handle groove The pin hole 212 is drilled in the 211, and when the wire replacement operation is carried out by hand or the tip of a manual tool having a rod with a thin diameter like a screwdriver is inserted into the pin hole, the wire holder is connected to the telephone line branch terminal. It is isolated without any pressing at.

As described above, the wire fixing connecting device of the present invention is a configuration of an inclined jaw formed by folding the lower end of the wire creep so that the wire creep is firmly fixed between the wire insertion hole and the locking jaw of the branch terminal, and the wire is inserted into the wire holder. One or more balls can be used to reduce required parts and to reduce the size of the parts, simplifying the size and structure of the telephone line branch terminal and simplifying work by temporarily connecting two wires. The support and the support groove in the unfolder push the wire insertion and tighten the wire creep in the inserted state, and the contact between the wire wire and the wire creep increases, and at the same time, it maintains a stable assembly that is not released by the wire wire being pressed. When the holder is separated by the messy groove and pin hole of the wire holder, The advantage is that the contact is very efficient.
