Description

[Detailed Description of the Invention] "Industrial Application Field" This invention is applicable to, for example, contact pads formed in a row along one side of an IC element, and then formed in two rows with an interval twice that of the contact pads. The present invention relates to an arrangement conversion connector used for connecting to a terminal hole of a wiring board.

``Prior Art'' As shown in FIGS. 3 to 5, a plurality of contact pads 12 are formed along one side of a main body 11 of an IC element at intervals a, and the IC element is connected to a wiring board 1. When connecting to the wiring board, two rows of through holes 14 and 15 are formed in parallel on the wiring board, and the spacing between the through holes 14 and 15 in each row is 2a, and the contact pads 12 are alternately connected to the through holes 14 and 15. and 15.

In this way, an arrangement conversion connector is used to distribute and connect one row of contact pads to two rows of through holes.

The conventional arrangement conversion connector is 2 as shown in Figure 6.
Different types of contacts 16, 17 are used. These contacts 16 and 17 are formed by pressing an elastic metal plate, and each intermediate portion thereof has a fixed portion 18 and 19.
One end of the fixed parts 18 and 19 is bent at a substantially right angle and extended upward in the figure, and the plate surface is bent toward the fixed part 1 from one side of the extended end.
8 and 19 and are bent and extended substantially parallel to each other, and each extension end is used as a contact point 21 and 22.

The contactor 16 is connected to the terminal 23 from the other end of the fixed part 18.
is extended downward as a whole. After the contactor 17 is extended in the front-rear direction from the other end of the fixed part 19,
The plate surface is bent and extended at almost a right angle to form an extension connection part 2.
4, and a terminal 25 is integrally extended downward from the extended end.

As shown in FIG.
1 and 22 are arranged alternately so that the interval is a, and the fixing parts 1 are attached to the insulating material box (not shown in the figure).
8 and 19 are press-fitted and held. Fixed part 18,
In order to ensure the press-fitting of 19, the protrusions 26, 2
7 is pushed out from the board surface. The spacing between the terminals 23 of the contactor 16 is 2a, and the terminals 25 of the contactor 17 are arranged at a spacing of 2a by being shifted by the extension connecting portion 24 with respect to the arrangement of the terminals 23. Therefore, the contacts 21 and 22 are connected to the contact pad 12 in FIG.
When the terminals 23 and 25 are brought into contact with the through holes 14 and 15, the terminals 23 and 25 can be inserted and connected to the through holes 14 and 15, respectively.

A conventional arrangement conversion connector using contacts 31 and 32 as shown in FIG. 7 is also known. This is also made by punching a metal plate, with the intermediate parts serving as fixing parts 33 and 34, respectively, and one end of which is bent and extended upward within the plane of the plate as shown in the figure, and then folded back parallel to the fixing part. , contacts 35 and 36 are formed at the folded free ends. The contactor 31 has a terminal 37 extending downward from the middle part of the fixed part 33 extending back and forth. The contactor 32 is extended by bending the plate surface of the other end of the fixed part 34 extending back and forth at a right angle, and a terminal 38 extends downward from the extended end. Fixed parts 33, 34
Projections 41 and 42 for press-fitting and fixing are integrally formed on the. In this case as well, as shown in FIG. 7, the contacts 31 and 32 are alternately arranged with a spacing of a between the contacts 35 and 36, and are held in a casing (not shown).

Assuming that the contacts used in the conventional arrangement conversion connectors shown in Figs. 6 and 7 are unfolded on a flat surface, it will be easy to understand that they can be removed based on their shape. Metal plates cannot be used effectively and many parts are wasted. Furthermore, it is difficult to punch out two types of contacts from a metal plate with the contact spacing set to a, so it is necessary to form each contact one by one and attach them to the case one by one. It also had the disadvantage of requiring a number of steps to assemble it.

"Means for Solving the Problems" In this invention as well, two types of contacts are provided, a first contact and a second contact, and these first and second contacts are made by bending an elastic metal plate. The plate surfaces of the first contact and the second contact are substantially parallel to the contact arrangement direction and the terminal arrangement direction. 1st
A first contact and a second contact are formed to protrude to the same side from the plate surface of one end of each of the contact and the second contact, respectively. The first contact and the first terminal are provided in substantially the same plane. On the other hand, the second contact is located midway between the second contact and the second terminal.
A connecting extension part is integrally provided in correspondence with the positional deviation of the adjacent first terminal and second terminal.

In order to use such a first contact and a second contact, the first contact and the second contact can be punched out of a metal plate in a state that is equal to the distance a between the contact pads with which they are to be contacted, and the material It is very easy to handle, and it is also possible to punch out a metal plate, bend it, and then incorporate it into a case while the contacts are connected to the conveying section.

Embodiment FIG. 1 shows an arrangement conversion connector according to the present invention. The insulating material casing 51 is formed into a substantially rectangular parallelepiped,
A first contact 52 and a second contact 53 are alternately arranged and accommodated in this case. Both the first contact 52 and the second contact 53 are made by bending an elastic metal plate.

The intermediate portions of the first contact 52 and the second contact 53 are fixed portions 54 and 55, respectively. Fixed part 5
4 and 55 are formed in a rectangular shape, and claws 56 and 57 are pushed out and press-fitted and held in the case 51. Fixed part 5
Contact pieces 58 and 59 extend integrally from one end (the upper end in the figure) of 4 and 55, respectively, and the plate surfaces of the contact pieces 58 and 59 are bent into a V-shape in the figure, and the free ends of each are bent into a V-shape. The first contact 61 and the second contact 62 are formed by extending the free end plate surfaces thereof to the same side (opposite to the fixed part). These first contacts 61 and second contacts 62 are alternately arranged in a straight line with an interval a.

In the first contactor 52, a first terminal 63 extends from the other end (lower end) of the fixed portion 54 within its plate surface.
The second contact 53 is extended from the other end of the fixed part 55 by bending the plate surface at a right angle, and after the extended end is folded back and extended to face the fixed part 55,
A connecting extension part 64 is integrally formed by being bent and extended in a direction perpendicular to the fixing part again. The end of the connecting extension 64 is connected to one end of the connecting extension 65 parallel to the fixing part 55.
A second terminal 66 extends parallel to the first terminal 63 from the other end. In this case, the second terminal 66 is
The length of the connecting extension part 65 in the contact arrangement direction and the mounting position of the second terminal 66 are selected so as to face the terminal 63.

The protruding ends of the first terminals 63 and the second terminals 66 are substantially on the same surface, and the first terminals 63 are arranged in one row.
Further, the second terminals 66 are also arranged in a row parallel to this. The interval between the first terminals 63 and the interval between the second terminals 66 are both 2a, which is twice the interval a between the first contact 61 and the second contact 62. In this example, in order to stably hold the connecting extension part 65 in the case 51, it is press-fitted and fixed to the case 51, and a protrusion 67 is formed by extrusion to ensure the press-fitting.

FIG. 2 shows a state in which the first contact 52 and the second contact 53 are developed on a plane. First contact 5
2. The extension directions of the second contacts 53 are parallel to each other, and the second contacts 53 are arranged with an interval of a. The connecting extension part 65 and the second terminal 66 are located on an extension of the protruding end of the first terminal 63 . When the first contact 52 and the second contact 53 are punched out along one side edge of the elastic metal plate 68 in such an arrangement, the contact side between each of the first contact 52 and the second contact 53 is cut out. In the part, the fixed part 5
4 and 55 are connected at one end of the connecting portion 69, and the other end of the connecting portion 69 is connected to a conveying portion 71 formed of one side of the metal plate 68. In this state,
In other words, the first
The contact 52 and the second contact 53 are bent into a desired shape with respect to their plate surfaces. Furthermore, a first contact 52 and a second contact 53 are attached to the housing 51 as necessary.
