DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact forming method and an isometric right angle connector formed by using the method.

[0002]

2. Description of the Related Art As an angle type card edge connector, there has conventionally been an equal-length right-angle connector in which the length of a plurality of contacts is made equal to prevent a difference in signal transmission time between the contacts.

As this type of connector, for example, FIG.
Each right angle contact 91 which is bent at a right angle as shown in FIG.
As shown in the figure, the housing 90 is inserted from the back side. One end of the right angle contact 91 is located in a receiving hole with a mating connector or the like inside the housing 90, and the other end is fixed to the printed circuit board 93 by soldering.

[0004]

In the conventional equal-length right-angle connector described above, as the number of cores increases in the bending process for changing the terminal direction of each contact, the number of dies corresponding to the number of cores increases. Required. Therefore, as the number of cores increases, the time required for assembling increases and the workability deteriorates. In addition, the number of molds increases, which increases the cost.

The present invention has been proposed in order to solve the above problems, and a contact forming method and a contact forming method capable of shortening the assembling time and reducing the cost even if the number of cores is large. It is an object of the present invention to provide an equal-length right angle connector.

[0006]

According to the present invention, a plate member is pressed or etched to form a predetermined number of core portions each having the same longitudinal length, and a connecting portion connected to both ends of the core portion. After obtaining a contact plate consisting of: affixing an insulating tape to both sides of the contact plate and to a region excluding both end portions of the respective core portions, contact the contact plate in a direction at 45 degrees to the longitudinal direction. The contact forming method is characterized in that after the core is bent in a lump for the number of cores until both ends thereof are on the same plane, each core and the connecting part are cut to form a contact.

Further, according to the present invention, an isometric right-angle connector characterized in that the insulator is provided with the contact.

Further, according to the present invention, there is provided an equal-length right-angle connector, wherein the insulator is molded on the insulating tape so as to cover the entire insulating tape.

Further, according to the present invention, there is provided an isometric right angle connector, wherein the insulator is molded at a base portion of the core protruding from the insulating portion.

Further, according to the present invention, the insulator is formed in advance, and the insulator is formed by fitting the insulator into a base portion of the core protruding from the insulating portion. An angle connector is obtained.

[0011]

According to the present invention, the contacts having the same length are arranged in parallel, and the contacts are bent at a predetermined position at an angle of 45 degrees so that the contacts are arranged at a right angle. , All the contacts can be bent together.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS A method for forming a contact according to the present invention will be described with reference to FIGS. As shown in FIG.
Cores 11 arranged in parallel (hereinafter referred to as contacts)
Can be obtained by etching or pressing a plate material. A connecting portion 12 (such as a carrier) is connected to each end of the contact 11, and the contact plate is formed by the contact 11 and the connecting portion 12.
FIG. 2 shows a covering (hereinafter referred to as an insulating tape) 13 made of an insulating material, which is cut into a square having a dimension shorter than the dimension of the contact 11, and two pieces having the same dimension are prepared. Have been.

As shown in FIG. 3, insulating tapes 13 are bonded from both sides (front side and back side) of the contacts 11 connected to each other by the connecting portions 12. At this time, both ends of the contact 11
Exposed to form a connection with a mating connector or the like. Then, when the contact plate is bent along the diagonal line of the insulating tape 13, the result is as shown in FIG. Thereafter, each contact 11 and the connecting portion 12 are cut.

Next, as shown in FIG. 5, the insulator 15 is entirely molded into the cut portion of the connection portion 12 except for the connection end of the contact 11 to obtain an isometric right angle connector.

The mold-in of the insulator is:
As shown in FIG. 5, it is not necessary to perform the entire process. As shown in FIG. 6, the insulator 17 may be formed by molding only the exposed base portion of the contact 11.
Further, as shown in FIG. 7, the insulator 19 is not a molded-in member, but may be a member formed in advance into the contact 11.

FIG. 8 shows the same length right angle connector shown in FIG. 5 connected to the daughter board 20.
The lower contact 11 is inserted into a through hole 21 formed in the daughter board 20, and the contact 11 and the land 23 are electrically connected by solder 25.
It should be noted that on the right side of FIG.
Are shown, and the through hole 3 of the backplane 30 is shown.
1 has a socket contact 32 connected to a land 33 by solder 35. FIG. 9 shows a connection state between the equal-length right-angle connector of the present invention and the socket contact 32 of the backplane 30.

[0017]

According to the present invention, the contacts having the same length are arranged in parallel, and the contacts are bundled at a predetermined position and bent at an angle of 45 degrees so that the contacts become a right angle. Since it is only necessary to arrange and mount the insulators to these by molding in, there is no need to prepare a plurality of types of molds to obtain individual bent contacts, and the manufacturing cost can be significantly reduced. it can. In addition, since the assembling operation is very simple, the manufacturing cost can be reduced in this respect as well.
