Description

[Detailed Description of the Invention] This invention relates to a telephone connector that has been standardized, for example, by the US FCC standards, and is widely used in offices, homes, etc. to connect telephone lines.

As a conventional telephone connector of this type, there is a structure shown in FIGS. 1 and 2, which was previously proposed by the applicant and others. That is, as is clear from these figures, this configuration has a plug insertion port 3 opened at the upper center of the front wall 2, a plurality of guide grooves 5 at the lower middle of the rear wall 4, and a bottom wall. A box-shaped body member 1 in which the same number of support grooves 7 are formed in each of the front half portions of six faces, and is fitted and locked to this body member 1 from the rear face side, and is overlapped on the bottom wall six faces. A holder member 8 having a holder part 9 projecting forward as shown in FIG. , and the tip end curved like the tip of the holder part 9 is elastically moored in each of the guide grooves 5 to form the plug contact part 1.
0b and a spring member 10 made of a good conductive wire material, and a lead wire is crimped to each terminal portion 10a, or each terminal portion 10a is inserted into a printed circuit board and soldered, and the plug is inserted. The plug 11 pushed through the opening 3 is used by being in elastic contact with each of the plug contact portions 10b within the range of each guide groove 5.

In this way, for conventional telephone connectors,
A square spring member 10 as a current-carrying contact member,
Each terminal portion 1 is bent and protruded from the lower part of the body member 1.
0a, and the processing of each terminal portion 10a is as follows.
Since this is done by crimping the lead wires or inserting them into the printed circuit board and soldering them, the process is extremely troublesome, and not only is the workability poor and there is a risk of incorrect wiring, but it also takes up a large amount of space. This had the disadvantage that it was not possible to compile a compact summary.

In view of these conventional drawbacks, this invention allows the printed circuit board to be directly inserted into the telephone connector itself, and connects the terminal portion of each spring member as a current-carrying contact member directly to the conductive portion of the printed circuit board surface. It is designed to connect.

Hereinafter, one embodiment of the telephone connector according to the invention will be described in detail with reference to FIGS. 3 to 6.

3 to 5 show the structure of the telephone connector according to this embodiment. In the embodiments shown in FIGS. 3 to 5, the above-mentioned FIGS.
The same reference numerals as in the conventional example in the figure represent the same or corresponding parts, and in this embodiment, the body member 1
The groove depth of the plurality of support grooves 7 formed on the bottom wall 6 of the is made slightly deeper, so that each spring member 10 supported by the support grooves 7 can be elastically operated up and down in a supported state. , the rear lower part of each support groove 7 is opened toward the rear wall 4 side to form a connection port 13 into which at least the end of the printed circuit board 12 can be detachably inserted from the rear; A proximal end portion extending from 7 faces the connection port as a terminal portion 10c projecting in a convex shape.

Therefore, in the configuration of this embodiment, the body part 1
As shown in FIGS. 4 and 5, the printed circuit board 1 is connected through the connection port 13 opened at the bottom of the rear wall 4.
2, the terminal portion 10 of each spring member 10 is connected to the printed wiring on the printed circuit board 12, that is, the conductive portion 12a such as copper foil.
c are connected by elastic contact, and in this state, as described above, by inserting the plug 11 from the plug insertion port 3 and making elastic contact with each plug contact portion 10b, it is possible to use the plug 11 in exactly the same manner as before. .

Here, several examples of usage patterns in this embodiment are shown in FIGS. 6a, b, and c. That is, as shown in FIG. 5, in FIG.
Lead wire 14 is connected to terminal portion 12b of printed circuit board 12.
In the case of soldering, the same printed circuit board 12 is also combined with another main printed circuit board 15, as shown in FIG.
When the conductive parts of both boards 12 and 15 are soldered, FIG. This is a case in which the devices are connected, and in this way, various usage patterns can be adopted and sufficient effects can be achieved in each case. In addition, when using two or more telephone connectors, they can be connected together on one printed circuit board, streamlining the assembly, and in this case, lead wire connection.
The greater the number of contacts, the greater the cost advantage compared to the conventional method, and the advantageous advantage is that the amount of lead wires used can also be reduced.

As detailed above, according to this invention, the telephone connector itself is configured so that the printed circuit board can be directly inserted and used. Processing can be carried out extremely easily and with good workability.
The fear of miswiring can be completely eliminated, the usage patterns can be expanded, and at the same time, the occupied area can be reduced, and the whole can be made compact. Also, contact with the terminals of the printed circuit board to be inserted,
Not only is the contact made using the elasticity of the spring itself reliable, but the contact between the printed circuit board and the plug works to increase the contact pressure with each other, making the contact even more reliable. The overall structure is relatively simple and has the advantage of being easily and inexpensively provided.
