Description

  The present invention relates to a modular jack distributor (hereinafter referred to as a modular distributor) used in a telephone line or the like. More specifically, the present invention relates to a modular distributor that can simplify the structure of a conventional modular distributor, reduce the number of parts, and reduce the assembly process to provide a stable quality product.

  The modular distributor is a distributor that takes a form in which when one modular plug is inserted into a single-port modular socket, at least two modular sockets are arranged on the back of the plug. The modular distributor has the advantage that it can be used as a modular socket with at least two ports, even if there is only one socket for the modular socket. Widely used in fields such as tuners.

  However, the conventionally known modular distributor has a large number of parts as described with reference to FIGS. 5 to 7, and as a result, the machining process and the assembling process both have a large number of processes and are not suitable for automatic machining and automatic assembly.

  FIG. 5 is a sectional view of an assembled state of a known modular distributor. In FIG. 5, A is a plug-side main body having a lock lever a on the upper surface, B is a cover of a two-port modular socket formed side by side on the back side of the plug-side main body A, and C1 and C2 are the socket cover B. It is a support body of contacts (contactors) arranged inside, and is an insulator formed by a block-like insulator.

Here, a covered wire D in which one wire is folded into two is embedded in the plug-side main body A, and a contact E connected to the covered wire D is formed on the lower surface side of the plug main body A. Is provided.
On the other hand, both ends of the covered wire D are stripped to be bare, after the bare wires F1 and F2 respectively embedded in the two insulators C1 and C2 disposed in the socket on the back side of the plug-side body A. The ends are connected by crimp terminals c1 and c2.

  The two insulators C1 and C2 having embedded and supported bare wires F1 and F2 formed on the contacts C1 and C2 at the tip side are supported while being covered by a socket cover B having a socket opening on the socket side. Formed in modular socket Sm. In addition, b is a pushing rod for pushing down the lock lever a.

  Next, the covered wire D, the two bare wires F1 and F2, the crimp terminals c1 and c2 and the two insulators C1 and C2 in the known modular distributor are shown in the process charts of FIGS. 6 (a) to 6 (f). Since it is assembled in the form illustrated, this point will be described.

  The straight covered wire D peels off the coating at both ends to expose the core wires d1 and d2. By exposing the bare bare wires F1 and F2 to the exposed core wires d1 and d2 at both ends, respectively, at the end faces, and clamping the core wires d1 and d2 and the bare wires F1 and F2 with crimp terminals c1 and c2. Connect (refer to FIGS. 6A and 6B). CL is a tool clamper.

  Pass the bare wires F1 and F2 at both ends connected by the crimp terminals c1 and c2 through the insulators C1 and C2, respectively, bend the part protruding from the insulators C1 and C2 upward, and socket beyond the bent part. The contact is formed on the side contact (see FIGS. 6C to 6E).

  After that, the covered wire D is folded in half at the intermediate portion (see FIG. 6 (f)), and the folded wire covered wire D is inserted into the plug-side body A not covered with the cover B in this state ( (See FIG. 7). Here, the plug-side contact E is connected to the covered wire D inserted from below. On the other hand, two insulators C1 and C2 are arranged side by side on the back side of the plug-side main body A, and a socket cover B is attached to form a modular distributor of the form shown in FIG.

  However, the above-described known modular distributor requires the parts of the push rod b and the crimp terminals c1 and c2 in addition to the parts from the plug-side main body A to the two bare wires F1 and F2. There are many points, and the two bare wires FI and F2 that are in contact with the coated wire D must be clamped and connected with the crimping terminals c1 and c2. However, there is a drawback that it takes a lot in proportion to the number of parts.

Among the difficulties in the known modular distributors, for the difficulty of connecting the lines D, F1 and F2 to be used, contact on the input side (plug side) and output side (socket side) with a single line that does not require connection The technique which forms is proposed by patent documents 1-3.

  Therefore, the present invention proposes a structure of a modular distributor that significantly reduces the number of parts compared to known modular distributors, and in particular, eliminates the need for insulators as parts. It is an object to provide a modular distributor that not only can be made but also has high electrical stability due to its simple structure and is unlikely to fail.

  In order to solve the above-mentioned problems, the modular distributor of the present invention comprises a block-like plug-side body having a lock lever on the upper surface and a plug-side terminal on the lower surface of the tip, and the plug-side body. A socket-side main body coupled to the back surface of the socket and having socket ports arranged vertically, and a bent single wire conductor is connected to the plug-side terminal while the conductor is bent. The plug-side main body and the socket-side main body are arranged so that the tip end side of the plug becomes a socket-side terminal.

A more specific configuration of the modular distributor of the present invention is as follows:
The block-shaped plug-side main body having a lock lever on the upper surface has a beam insertion hole into which the coupling beam provided protruding from the rear surface of the socket-side main body is inserted, and a socket-side main body on the rear surface of the plug-side main body. A connecting portion with the socket side body to be connected to the back surface of the plug, and a plug side contact at the tip of the insertion hole;
The socket side body is provided with a support portion of a single wire conductor connected to the plug side contact, and the coupling beam provided on the back surface of the socket side body and the front side of the socket side body and vertically with respect to the beam. Two socket ports arranged, and a single wire conductor support formed on the socket side contact, provided on the bottom side of each socket port,
The support formed on the plug-side main body and the socket-side main body holds a single-wire conductor that is not joined to each other, and the two main bodies are combined and integrated, and the single-wire conductor is connected to the plug-side contact and the socket-side contact Formed in the
It is characterized by.

  The method of manufacturing a modular distributor of the present invention having the above-described configuration includes a beam insertion hole into which a coupling beam provided so as to protrude from the back surface of the socket side body is inserted, and a back surface of the plug side body. The coupling beam provided on the back surface and the socket on the plug side body provided with a connection portion on the socket side body provided and connected to the back surface of the socket side body, and a plug side contact at the tip of the insertion hole A socket side body including two socket ports arranged on the top and bottom with respect to the beam on the front side of the side body, and a single wire conductor supporting portion formed on a socket side contact on the bottom side of each socket port; When the coupling beam is tightly inserted into the insertion hole so as to be coupled and integrated, the single body conductors without joints are held by the support portions formed on the plug side body and the socket side body, and the both bodies Bound integrated the single wire conductor is characterized in that formed on the socket side of the contact as well as connected to the plug side contacts.

  The modular distributor of the present invention has a block-like plug-side body having a lock lever on the upper surface and a plug terminal on the lower surface of the tip, and is connected to the back surface of the plug-side body, and socket ports are arranged vertically. A single-sided conductor that is bent and connected to the plug-side terminal, and the tip side of the conductor serves as the socket-side terminal. Since it is arranged inside the main body and the socket side main body, the number of parts is less than that of known modular distributors. Especially, since the insulator as an independent part is not used, the processing and assembly processes are simple. In addition, since it has a simple structure, it has high electrical stability and few failures.

Next, an embodiment of the modular distributor of the present invention will be described with reference to the drawings.

(a)-(e) is a sectional side view for demonstrating the assembly process of this invention modular distributor.

  1 to 4, reference numeral 1 denotes a plug-side body integrally provided with a lock lever 2 on the upper surface, and the lock lever 2 is integrally provided with a push rod 3 (pressing rod 3). The plug-side main body 1 is formed with a beam insertion hole 4 in a substantially horizontal direction along which the coupling beam 9 described later is closely inserted. The upper end of the push rod 3 is formed in a planar pressing part.

The bottom surface of the beam insertion hole 4 is formed with six grooves as an example for holding a plurality of conductors 7 for forming contacts to be described later, and on the front side (the left side in FIG. 1 (a)). An opening 4a that opens toward the lower portion is formed, and the plug-side contact 5 is embedded in the opening 4a (see FIG. 4A). There may be a case where at least two grooves are sufficient.
In the plug-side body 1, a socket coupling portion 6 coupled to a plug coupling portion 16 formed on the back surface of the socket-side body 8 described later is provided on the entrance side of the beam insertion hole 4 (the back side of the plug-side body 1). It is formed vertically.

  7B, the left end portion of FIG. 4B is formed in a plug-side connection portion 7a connected to the contact 5 of the plug side body 1, and the right end side of FIG. This is a single-wire conductor formed by bending a round bar-like conductor formed on the socket-side contacts 7b and 7c inside the socket-side main body 8 (see FIG. 4B). The same number of conductors 7 as the number of contacts to be set (four in the example of FIGS. 1 and 2) is used.

  This conductor 7 is formed by bending one conductive wire, forming a narrow parallel portion on the upper left and lower sides of the figure in the connection portion 7a on the plug side entering the beam insertion hole 4, and folding the conductor in half. The right half side of the conducting wire is formed in a wide laterally parallel portion up and down, and the two conducting wires are formed at portions that become the socket-side contacts 7b and 7c (see FIG. 4B).

  8 is formed on the back surface (left side of FIG. 4C) on the front side (right side of FIG. 4C) while forming a coupling beam 9 that is closely inserted into the beam insertion hole 4 provided in the plug-side body 1. The socket-side main body has two socket ports 10 and 11 arranged one above the other (see FIG. 4 (c)).

  In the socket side body 8, 12 is a support portion of the push rod 3 formed above the coupling beam 9, and 13 and 14 are the beam 9 below the bottom 10 a of the socket port 10 and the bottom 11 a of the socket port 11. Is a support groove into which contacts 7b and 7c on the socket side formed in parallel are inserted and arranged, and as an example, six grooves are arranged in parallel. Reference numeral 15 denotes a plug coupling portion that is coupled to the socket coupling portion 6 of the plug-side body 1 formed below the coupling beam 9.

  As shown in FIG. 4 (b), the single conductor 7 formed by bending one conductive wire at the plug-side connecting portion 7a and the socket-side contacts 7b and 7c is formed into a portion for the contacts 7b and 7c. Are inserted into the six support grooves 13 and 14 formed on the bottoms 10a and 11a of the socket port 10 and 11a, respectively. The coupling beam 9 is sandwiched from above and below by the connecting portion 7a. In this state, the coupling beam 9 is inserted into the beam insertion hole 4 of the plug-side body 1, and the coupling portion 6 formed on the back surface of the plug-side body 1 and the coupling portion 15 formed on the back surface of the socket-side body 8 are tightly coupled. The side main body 1 and the socket side main body 8 are combined and integrated (see FIG. 4D). The number of conductors 7 is the same as the number of contacts set on the plug side and the socket side.

  When both the main bodies 1 and 8 are joined and integrated, the parts that become the contacts 7b and 7c on the socket side from the bottom of the upper and lower socket openings 10 and 11 are the front of the socket openings 10 and 11 (right side of the figure). ) To the outside (see FIG. 4D).

  Therefore, the protruding portion of the conductor 7 is bent upward by about 90 degrees with the ends of the bottoms 10a and 11a of the socket ports 10 and 11 as a boundary (see FIG. 4 (d)), and then has a substantially lateral V shape. By bending in this way, the two modular sockets 10 and 11 are formed in the modular distributor according to the present invention (see FIG. 3).

  The modular distributor of the present invention is similar in use and function to a known modular distributor, except that the two socket ports 10 and 11 are provided vertically.

  The modular distributor of the present invention is as described above. Compared to the known modular distributor described with reference to FIGS. 5 to 7, (a) the connecting conductor including the plug side and socket side contacts is a single line (known) In the example, one covered wire and two bare wires are used), (b) Therefore, the crimp terminal is completely unnecessary, and (c) the insulator for supporting the socket side terminal is completely unnecessary. Thus, the number of parts can be greatly reduced.

  In addition, the modular distributor of the present invention can greatly simplify the machining process and the assembly process as a result of the reduction in the number of parts, and the structure is simple because the number of parts is small, which contributes to the simplification of the assembly process. In addition to this, the present invention brings about the unique effect of the present invention in that the performance and quality are also stabilized and homogenized.
