Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a connector used in a computer, an electronic exchange, a transmission device, etc., and more particularly to a connector having one end connected to a motherboard.

[0002]

[Prior Art]

 Conventionally, as shown in FIG. 3, this type of connector is constructed by press-fitting and fixing a plurality of columnar male contact portions 22 made of metal on the bottom of a rectangular tubular housing portion 21 made of an insulator. The outer end of each male contact portion 22 protruding from the housing portion 21 is soldered to the through hole 24 of the motherboard 23, while the inner end of each male contact portion 22 is attached to a daughter board (not shown). Female contacts of male and female connectors are connected.

[0003]

[Problems to be solved by the device]

 However, the above-mentioned conventional connector has a drawback that it has many processing steps and assembling steps because it is assembled by press-fitting a pressed metal male contact section into a molded insulating housing. .

Therefore, an object of the present invention is to provide a connector having a small number of processing and assembling steps.

[0005]

[Means for Solving the Problems]

 The connector of the present invention is formed by integrally forming a plurality of columnar male contact portions plated with conductive material on one surface of a rectangular plate-shaped contact holding portion made of plastic with both ends protruding from both sides. The male contact block is integrally formed by bending the joints to both ends of the male contact in parallel to the male contacts, and is joined to one surface of the male contact block through both ends. It is provided with a rectangular plate-shaped upper cover having a notched portion to surround it, and a rectangular plate-shaped lower cover joined to the other surface of the male contact block through both ends.

It is preferable that two or more male contact blocks are joined.

[0007]

[Action]

 In the above means, the conductive portion is formed by applying conductive plating to the male contact portion integrally molded with the contact holding portion from plastic.

[0008]

【Example】

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

1 and 2 are an exploded perspective view and a perspective view showing a usage state of a connector according to an embodiment of the present invention.

This connector has two male contact blocks 1 joined to each other and one surface (upper side in FIGS. 1 and 2) of one male contact block 1 (upper surface in FIGS. 1 and 2). It is composed of an upper cover 2 joined via both ends and a lower cover 3 joined to the other surface of the other male contact block 1 via both ends.

The male contact block 1 has a plurality of columnar male contact portions 5 plated with conductive material on one surface of a rectangular plate-shaped contact holding portion 4 made of non-platable plastic. The both ends of the contact holding part 4 are integrally formed by appropriately projecting both ends from both sides and forming a −face and a −face, and a joint part 6 is provided on both ends of the contact holding part 4 in parallel with the male contact part 5 (in FIG. 1). It is bent to the right end side) to be integrally formed, and a fitting concave portion 7 is formed on one surface of both joint portions 6, while a fitting convex portion 8 is formed on the other surface. 6 and the like and each male contact portion 5 are integrally molded by two-color molding with a plastic material that cannot be plated and a plastic material that can be plated, and the conductive plating is integrated with the contact holding portion 4. Success It is composed of a conductive film 9 formed by plating on both ends of each shaped male contact part 5, and a conductive pattern 10 formed by plating on one surface of an intermediate part for connecting both conductive films 9.

The upper cover 2 is formed into a rectangular plate shape with the same plastic or other insulating material as that of the male contact block 1, and also has a male connector portion 5 of each male contact portion 5 to enable fitting of a male connector described later. A rectangular notch 11 surrounding one end is formed on the other surface, and fitting projections 12 that can be fitted into the fitting recesses 7 of the male contact block 1 are formed at both ends of the other surface.

Further, the lower cover 3 is formed of a plastic or other insulating material similar to that of the male contact block 1 into a rectangular plate shape, and both ends thereof are formed with fitting recesses 13 into which the male contact block 1 can be fitted. Has been done.

Then, as described above, each male contact block 1 is fitted with the fitting projections 8 at both ends of one male contact block 1 and the fitting recesses 7 at both ends of the other male contact block 1. While being joined to each other, the fitting concave portions 7 at both ends thereof and the fitting convex portions 12 at both ends of the upper cover 2 are fitted to one surface of one male contact block 1 to join the upper cover 2 and The fitting projections 8 at both ends of the male contact block 1 and the fitting recesses 13 at both ends of the lower cover 3 are fitted to the other surface of the male contact block 1 to join the lower cover 2 to assemble the connector.

In the connector thus assembled, as shown in FIG. 2, the other end of each male contact portion 5 is soldered to the through hole 15 of the motherboard 14, while the other male contact portion 5 is The female contact 18 of the male connector 17 attached to the daughter board 16 is connected to one end.

In the connector having the above-mentioned structure, the conductive portion is formed by applying the conductive plating to the male contact portion 5 integrally formed with the contact holding portion 4 from plastic, so that the conventional male contact portion and the housing portion are formed. It is not necessary to form each of them separately, and it is possible to reduce the number of assembling steps for press-fitting the male contact portion into the housing portion.

In the above-described embodiment, the case where two male contact blocks 1 are joined has been described, but the present invention is not limited to this, and one male contact block 1 may be used, or three male contact blocks 1 may be used. The above may be applied.

[0018]

[Effect of the device]

 As described above, according to the present invention, the conductive portion is formed by applying the conductive plating to the male contact portion integrally formed with the contact holding portion by the plastic. The effect is that the number of processes can be reduced.
