[Problem that the idea aims to solve]

In the conventional horizontal modular jack 1 described above, the contact pins 6 are arranged vertically (Fig. (bending direction shown in x in Fig. 8) and horizontal direction (bending direction shown in y in Fig. 8) Therefore, the contact pin 6 is formed of a round pin (wire) that can be bent in both directions. There is. However, the round pins are expensive, increasing the cost of horizontal modular jacks. It is the cause of this.

[0006] Therefore, there are technical issues that need to be solved to reduce the cost of horizontal modular jacks. A problem arises, and the present invention aims to solve this problem.

[0007]

[Means to solve the problem]

This idea was proposed to achieve the above purpose, and the casing Horizontal modular where the attached contact pin is bent horizontally and vertically. In jacks, the contact pins are shaped by press punching a metal plate. At the same time, the contact pin is bent in advance in the horizontal or vertical direction. The contact pin is attached to the casing, bent in the other direction, and the contact pin is attached to the casing. We offer a horizontal modular jack that features a top pin installed in a predetermined position. This is what we intend to offer.

[0008]

[Effect]

This idea is based on the fact that the contact pins of a horizontal modular jack are pressed into a metal plate. It is formed inexpensively by punching. The contact pin is bent in one direction in advance. has been completed. That is, for example, the contact pin is formed into an L shape bent in the vertical direction. Therefore, the contact pin is attached to the casing of the horizontal modular jack. It is bent horizontally.

[0009]

【Example】 Hereinafter, one embodiment of this invention will be described in detail with reference to FIGS. 1 to 6 of the accompanying drawings. In the figure, 10 is a horizontal modular jack, and 11 is the horizontal modular jack. 12 is a fitting hole in the casing of the block, and a plug (not shown) is inserted into the fitting hole 12. It is configured to be removable. The casing 1 is attached to one side of the casing 11. A first groove that is L-shaped in plan view and opens the front surface of the flange 13 of No. 1 and the inner surface of the insertion hole 12. 14, 14... are formed.

0010 As shown in FIGS. 1 and 2, the contact pins 1 are placed in the first grooves 14, 14... 5, 15... and guide the tip end obliquely from the first groove 14, 14... It is exposed in the insertion hole 12. In addition, the contact pins 15, 15... The tip end is a slide guide 17,1 formed by cutting out the rear wall 16 of the casing 11. 7..., the vertical movement is regulated, and the contact pins 14, 14... contact each other. It prevents you from doing so. Then, fit the plug into the fitting hole 12 and can be connected to the contact pins 15, 15, etc. of the horizontal modular jack 10. It is formed like this.

[0011] As shown in FIGS. 1 and 3, one side of the casing 11 is provided with the first groove. Second grooves 18, 18 in the horizontal direction across the flange 13 at heights corresponding to 14, 14... It forms... The second grooves 18, 18... are open at the rear and sides, and the flange part 13 are connected to the first grooves 14, 14... through insertion holes 19, 19... There is. Furthermore, the protruding walls 20, 20... forming the second grooves 18, 18... The extension distance is shortened, and each of the second grooves 18, 18, . . . is provided in steps. And the second The contact pins 15, 15... are fixed in the grooves 18, 18... of the respective contact pins 15, 15... The lower end portions of the pins 15, 15, . . . are formed so as to protrude downward.

0012 As shown in FIGS. 1 and 2, the lower end portions of the contact pins 15, 15... It is bent into a dogleg shape. As shown in FIGS. 2 and 4, the casing A lock pin 21 is attached to one side of the back surface of the plug 11, and the lock pin 21 and the The lower ends of the tact pins 15, 15... are engaged with holes etc. in the board (not shown), and the horizontal module is installed. The modular jack 10 is assembled to the board.

[0013] One side of the horizontal modular jack 10 is fixed with the contact pins 15, 15... In order to secure the lock pin 21, the contact pin 15, 15... Once installed, the horizontal modular jack 10 can be fixed to the board. Therefore, the number of parts In addition to reducing costs by reducing can proceed. Also, the lower ends of the contact pins 15, 15... are connected to the electrodes of the board. be soldered.

[0014] On the other hand, the contact pins 15, 15... are attached to the metal plate 22, as shown in FIG. They are formed by press punching and are connected by a connecting bar 23. or, The contact pins 15, 15, . . . are bent in advance into an inverted L shape. and, When attaching the contact pins 15, 15... to the casing 11, When the contact pins 15, 15... (four in this example) are connected, Figs. 3 to the second grooves 18, 18... and the insertion holes 19, 19... of the casing 11 shown in FIG. Insert both sides at the same time. The contact pins 15, 15... are connected to the projecting walls 20, 20... The rear ends are press-fitted into the first groove until they abut against the corners of the contact pins 15, 15... 14, 14... protrudes further forward.

[0015] As shown in FIGS. 1 and 6, the contact pins 15, 15... are bent into an L shape. Therefore, the direction of rising upward from the bottom end (direction of arrow a in Figure 6) is It is bent in the vertical direction (bending angle direction x of the contact pin 15 in FIG. 6) and forward ( It extends in the direction of arrow b). Furthermore, the contact pins 15, 15... are in the first groove. 14, 14... in the horizontal direction (bending angle direction y of contact pin 15 in FIG. 6) and is guided toward the inside of the casing 11 (in the direction of arrow c in FIG. 6).

[0016] Further, the contact pins 15, 15... are further horizontally moved near the inner surface of the fitting hole 12 ( The contact pin 15 is bent diagonally backward (arrow in FIG. 6) in the bending angle direction y of the contact pin 15 in FIG. It is provided obliquely in the direction indicated by mark d) and is exposed within the fitting hole 12 . And casing 11 protruding walls 20, 20... near the rear ends of the contact pins 15, 15... The contact pins 15, 15... are fixed to the casing 11 by welding, and the The contact pins 15, 15... are kink-processed as described above, and the lower ends are Cut to specified length.

[0017] Since the contact pins 15, 15... are bent in the vertical direction in advance, they can be bent horizontally. By bending only the direction, the contact pin 15 of the horizontal modular jack 10 can be bent. Can be formed into a certain shape. The contact pins 15, 15... are shaped by pressing a metal plate. Since the contact pin 15 is bent in the horizontal direction (the bending angle direction y of the contact pin 15 in FIG. 6), Can be easily bent. Furthermore, multiple contact pins 15, 15... can be connected simultaneously. Since it is assembled to the casing 11, the assembly work is significantly simplified and productivity is improved. can do.

[0018]

[Effect of the idea]

As detailed in the above example, this idea involves press punching a metal plate. to form the contact pins of the horizontal modular jack, and to form the contact pins of the horizontal modular jack. The pin is bent in advance in the vertical or horizontal direction. For example, the contact If the pin is bent vertically, the contact pin can only be bent horizontally. Since it is formed into a predetermined shape using a metal plate, there is no need for expensive round pins. An inexpensive contact pin can be used.

[0019] Therefore, the cost of the horizontal modular jack is reduced, and the contact pin This idea has practical value, as it simplifies the installation process and improves productivity.
