Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a multi-core connector, and particularly to a male-type multi-core connector that is used while being fixedly mounted on a board.

[Conventional technology]

There are various types of multi-core connectors installed on boards.
Among these, multi-core connectors in which connection contactors are arranged in a row are relatively often used these days. Conventional examples are shown in Figures 6 and 7. In FIGS. 6 and 7, the connector main body 50 is formed in an L-shape, and a plurality of male contacts 52 are arranged in a line on the rising portion 50A. The rising portion 50A of the connector main body 50 has its rear side fixed to the board 60.
The other end of each male contactor 52 is connected to a predetermined printed circuit on the contactor 0.

In FIG. 6, the reference numeral 70 indicates a female connector, and the reference numeral 7l indicates a female contactor thereof. Also code 80
indicates the board. At the bottom of the connector main body 50 in FIG. 6, a guide section 50B for attaching and detaching the female connector is provided. The plurality of male contacts 52 attached to the rising portion 50A of the connector body 50 are arranged such that the other end, which is attached to the board 80, is arranged in a staggered manner, and the female contactor side, which is one end, is arranged in a staggered manner. The parts arranged in the same line are arranged in a line. Therefore, all of the male contacts 52 are bent in a Z-shape at the part buried in the rising part 50A at one end, and at the same time, the direction of the bent part is changed for every other contact in the connector body. 50
It is installed on. [Problems to be Solved by the Invention] In the conventional male electrical connection connector described above, when processing the male contacts 52 to be used by stamping, the developed shape of the adjacent male contacts is bent into a Z-shape. Since the shapes of the extended parts are exactly the same, there is no dimensional space between adjacent male contacts, especially in the shoulder part of the center of the male contacts, and the press mold used for processing Not only was it difficult to manufacture, but various problems occurred during production, such as difficulty in handling and maintenance. In addition, since stamping cannot be done at once, every other male contact 52 is stamped and then plated, and in the subsequent assembly process, after pressing every other male contact 52 onto the contactor body 50, the inverted male contact 52 is plated. Since it was necessary to press-fit the mold contact 52 again, stamping. The drawbacks were that the plating and assembly processes required twice as much work, twice as much material, and high costs. To explain this in more detail, for example, as shown in Figure 6,
The conventional male contact 52 is bent in a Z-shape at one end 103, which is a contact part, and the tips of this one end 103 (see FIG. 7) are lined up in a row, and the other end, which is a press-fit part, is arranged in a row. , for example r1,27X1.905 (mm)J
The contacts are held in the contactor body 50 in a staggered manner. Figure 7 shows the arrangement of the male contact 52 without the housing. Here, the male contact 52 is connected to the rl. 27
Male contacts 52 adjacent to each other at a pitch of (mm) J are arranged symmetrically.

The width of the sigolder portion 104 of the male contact 52 is rl
．． It is approximately 0 (mm)J. Therefore, r1.
27 (mm) When the board thickness is rQ. 4 (mm)J
If this is the case, it will be difficult to construct the mold. Therefore, in reality r
The method used was to use a combination of two male contacts 52 stamped at a 2.54 (mm) J pitch. [Object of the Invention] An object of the present invention is to improve the disadvantages of the conventional example and, in particular, to provide a male multi-core connector with good productivity.

[Means to solve the problem]

In the present invention, a connector main body, a plurality of male contacts whose center portions are supported by the connector main body at predetermined intervals, and one end of each of the male contacts are disposed along the same line, and the other ends are disposed along the same line. In a male multi-conductor connector whose ends are staggered in the same direction, the first male contact is formed into a straight line and is supported by the connector body. and a second male contact which is bent into a Z-shape, and the first and second male contacts are arranged alternately along the same direction of the connector body. We have adopted a structure of providing equipment. This aims to achieve the above-mentioned purpose.

[For production]

By using a straight first male connector, it is possible to stamp the first and second male contactors using the same plate member, instead of stamping all the male contactors as in the conventional method. There is no need for bending, which eliminates the need to use two temporary members. Therefore, productivity can be improved and material costs can also be saved. It is also easier to integrate into the connector body. [Embodiment of the Invention] Hereinafter, an embodiment of the present invention will be described based on FIGS. 1 to 5.

The embodiment shown in FIGS. 1 to 5 includes a connector body 1, a plurality of male contacts 2.3 whose centers are supported by the connector body 1 at predetermined intervals, and each of the male contacts 2.3. 2.3, one end is arranged along the same line, and the other end is arranged in a staggered manner in the same direction. The male contacts actually include a first male contact 2 formed in a straight line, and a second male contact 3 whose portion supported by the connector body 1 described above is bent into a Z-shape. is used. These first and second male contacts 2 and 3 are alternately arranged along the same direction of the connector body 1 every other contact.

Figure 2 shows stamped products of the first and second male contacts 2.3. In FIG. 2, the first male contact 2 is formed in a straight line and is connected to the carrier 9 via a joint 10A. This first male contact 2 includes, from the top of the figure, a contact M part 11A, a shoulder part 1
2A. Press fit part 13A and board circuit connection part 14
It is formed by A.

Further, the second male contact 3 is formed in a two-shape shape when it is alone, and in a crank shape when the joint portion is included.

Reference numeral 10B indicates a joint portion. This second male contact 3 is also shown as tJJ[ 1 1 B,
The shape is defined by a shoulder portion 12B, a press fit portion 13B, and a board circuit connection portion 14B.

Each male contact 2.3 has shoulder portions 12A, 12B located at its center and a press-fit portion 1.
The first and second male contacts 2.3 are stamped so that they are connected to the carrier 9 through joints 10A and 10B of different lengths so that the processing and forming positions of the contacts 3A and 13B are different. It is then processed and subjected to the next plating process, etc.

To explain this in more detail, in the male multi-conductor connector of this embodiment, first male contacts 2 and second male contacts 3 are arranged alternately and connected to the connector body 1. The press-fit parts 13A and 13B of the first male contact 2 and the second male contact 3 are arranged in a staggered arrangement of "1.27 [閤] Xi.905 (kaku)", and the contact parts 11A, IIB is rl.27 (Kaku)
A part of the second male contacts 3 is bent in a Z-shape so as to be arranged in one row.

Further, a female multi-core connector 70 surface-mounted on the card 7 is fitted to this male multi-core connector, and the first male contact 2, the second male contact 3 and the female contact 7l are connected to each other. and are mechanically and electrically connected.

FIG. 2 shows the first and second male contacts 2 described above.
．． A perspective view of No. 3 after stamping is shown. In this case, the press fit portions 13A, 13B are all rl. 27
(En) xi, 905 [Kaku]'' are arranged in a staggered pattern. Here, to explain the cross-sectional shape (concave groove) of the press fin parts 13A and 13B, in this embodiment, the structural cross-sectional shape of the press fit part 13A is formed in an inverted N shape as shown in FIG. Further, the structural cross-sectional shape of the press-fit portion 13B is formed into an N-shape as shown in FIG. FIG. 5 shows the shape of the second male contact 3 before it is bent in the stamping die of the stamped product shown in FIG. 2 described above. Here, the sigolder portion 12A of the first male contact 2
The press-fit portion 13A, the shoulder portion 12B of the second male contact 3, and the press-fit portion 13B are adjacent to each other and are shifted in position. When stamping, if the shoulder parts 12A, 12B are in the same position as shown in the conventional example described above, the shoulder parts 12A,
12B is usually required to be larger than rl,O (m)J, but the pitch rl. 27 (kaku)'', the distance between the shoulder parts 12A and 12B becomes rO.27 (■)'', which makes processing difficult during stamping and very poor maintainability. If it is shifted,
Width of press-fit parts 13A and 13B Casilder part 1
Since the width is much narrower than that of 2A and 1 2B, there is more margin in the punching width, improving workability. Furthermore, when the stamping feed pitch is set to 2.54 (m)J, if the press-fit parts 13A and 13B are changed as shown in Figures 3 and 4, the tool removal will be symmetrical during processing. The structure of the kata becomes simple.Other structures and their effects are the same as in the conventional example described above.

〔Effect of the invention〕

As described above, according to the present invention, since the first male contact formed in a straight line and the second male contact bent in a double-shape are alternately provided on the connector body,
It is possible to provide an unprecedented and excellent male multi-core connector in which the processing and attachment work of each contact is facilitated, and productivity can be significantly improved at a relatively low cost.
