Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a contact suitable for connecting a package containing an integrated circuit or the like to a substrate.

[Prior Art] Generally, as shown in FIG. 5, a plurality of contact pads 24 arranged in a line on a package containing an integrated circuit etc. and a plurality of contact pads 24 bored in two lines at predetermined connector pitches 2a in a substrate 25 are used. There are cases where it is necessary to make one-to-one correspondence with the holes P.

In that case, for example, a connector in which contacts 8' and 9' shown in FIGS. 6a and 6b are assembled into an insulating housing is used.

The contacts 8' and 9' shown in FIGS. 6a and 6b both have a retaining part 1 held in the housing and a contact pad of the integrated circuit (indicated by symbol 24 in FIG. 5).
a contact part 2 for contacting the connector; an elastically deformable part 3 extending from the end of the holding part 1, curved in a certain direction, and having the contact part 2 connected to the tip; and a holding part 1 to be securely held in the connector. The press-fit part 4 that is press-fitted into the connector for the purpose of
It has terminals 5 and 6 for insertion into the hole P of. Moreover, an extension part 7 is provided which extends horizontally from the holding part 1 and is bent, and the terminal 6 is made to hang down from this extension part 7.

Such a contact is obtained by punching out a conductive plate material.

However, in this case, the punched contacts are not completely separated from the board;
Normally, in order to assemble multiple contacts into the connector housing at the same time, multiple contacts are each connected to a carrier, which is the rest of the plate, via an elongated bridge, so-called with a carrier. As a contact,
We handle all carriers.

[Problems to be Solved by the Invention] However, in conventional contacts with carriers, when the first or second contacts 8' or 9' are punched out of a conductive material, the terminal and the bridge are provided separately. Because of this, the shape had to be complicated, which resulted in the disadvantage that material removal was difficult.

Moreover, since the punch is punched with the extension 7 extending in the horizontal direction, extra material is required in the horizontal direction, resulting in a large amount of scrap, which is not economical. be.

Furthermore, when the same contacts are continuously punched out of a plate material, the pitch between the contacts is inevitably increased by the length of the extension 7 extending in the horizontal direction, as described above. As a result, the range of contact pitch selection is limited, which has the drawback of narrowing compatibility with the terminal pattern.

SUMMARY OF THE INVENTION In view of the above-mentioned drawbacks, an object of the present invention is to provide a contact that is easy to punch out and has excellent material removal.

[Means for Solving the Problems] According to the present invention, a plate-shaped holding portion having a plane defined by one edge portion and the other edge portion facing each other, and a plate-like holding portion for contacting an external terminal. a contact part,
an elastically deformable portion extending from the one edge portion and curved in a predetermined direction and coupled to the contact portion; a bridge terminal extending from one side of the other edge portion; and an extended end of the bridge terminal. A carrier formed by connecting the terminal, a notch provided at the upper end of the bridge terminal, an arm portion disposed on the other side of the other edge portion, and an insertion portion disposed on the extended end side of the arm portion. The arm portion extends in a direction perpendicular to the plane of the holding portion and has a predetermined angle with respect to the extending direction of the other edge portion, and the insertion portion includes: A contact with a carrier is obtained, which is characterized in that it extends in a direction perpendicular to the arm.

[Example] An example of the present invention will be described with reference to the drawings.

A contact 9 with a carrier according to the present invention shown in FIG. 1 is connected to a holding part 1 held in a housing 26 shown in FIG. 4 and an external terminal such as a contact pad (indicated by symbol 24 in FIG. It has a contact part 2 for making contact.

Among these, the holding part 1 is made by vertically bending each plate-like part between the holding part 1 and the plate part 20, and furthermore, the holding part 1 is formed with a flat surface 1a, and a part is formed with respect to the flat surface 1a. A press-fit portion 4 is provided which is expanded.

Further, an upper step part 10a and a lower step part 10b are formed by providing a step on the upper edge part of the holding part 1, and from one side of the plate part 20, this lower step part 10b corresponds to the plate part 20. An elastically deformable portion 3 formed by connecting the contact portion 2 to the elastic deformable portion 3 extends in a bent manner. A bridge terminal 29 extends from the other side of the plate portion 20 where the lower edge portion 12, which is the other edge portion of the holding portion 1, corresponds to the plate portion 20. At the upper end of the bridge terminal 29, there is a notch 2.
3 is formed, and the carrier 18 is connected to the extended end of the bridge terminal 29.

Further, a terminal portion 6' is integrally formed in the holding portion 1, extending from the lower edge portion 12. In this terminal portion 6', a portion 15 of the holding portion 1 is bent at an angle θ with respect to the direction of the other edge portion, and this portion 15 is further bent at a boundary portion (i.e., a joint portion) 14. Therefore, the arm part 13 is extended from the joint part 14 in a direction perpendicular to the plane 1a, and the insertion part 16 is formed by letting the extended end side of the arm part 13 hang down.

Here, the length of the arm portion 13 and its angle θ with respect to the plane 1a of the holding portion 1 can be selected as appropriate.
As shown in FIG. 5, the terminal portion 6' can be easily adapted to the hole P2. This means that contacts can be obtained that are compatible with various terminal patterns.

Next, a method of manufacturing such a contact 9 with a carrier will be explained based on FIG. 2.

Here, first, a blank material is punched out of a conductive material in the shape shown in FIG. 2 in advance. At this time, as can be seen from the figure, the blank material simply has terminals etc. extending vertically in parallel around the holding part 1, and has a simple structure that does not require a bridge, so it is punched. The work can be done easily, and material removal is very easy.

In addition, all the elements necessary for contact functionality are included.
Since they are arranged vertically around the holding part 1 and have no elements that protrude laterally, the range of selection of the pitch 2a between the contacts can be expanded compared to conventional contacts.

Next, out of the conductive material punched out from the blank material, first bend the plate-shaped part at right angles, and then
As shown in the figure, the holding part 1 and the plate part 20 are formed. Furthermore, the upper end of the plate part 20, that is, the thin part extending in a straight line from the lower step part 10b of the upper edge of the holding part 1 is curved to form the elastic deformation part 3, and the length of the arm part 13 and its holding part are curved. After determining the angle θ of the portion 1 with respect to the plane 1a as desired, a contact 9 with a carrier is obtained.

That is, the blank material here is specially processed to make the contact 9 with a carrier, and when such a blank material is used to manufacture a connector as shown in FIGS. 3 and 4, Punching work can be performed easily.

For example, in order to form contacts 9 with carriers having the number of cores necessary for assembling them into the housing 26 of the connector 21, the carrier 18 is cut at an appropriate position, and then the contacts 9 are assembled into the housing 26 at the contact pitch 2a. That's fine.

Specifically, contact 9 with carrier
and a separate contact 8 with a carrier that does not have a terminal portion 6' are assembled into the housing 26 so as to be adjacent to each other at the connector pitch a, and finally the carrier 18 of each contact 8, 9 with a carrier is assembled. , 18' are separated. At this time,
The contact 8 with a carrier is separated from the notch 22, and the contact 9 with a carrier is separated from the notch 23. That is, in the contact 9 with a carrier, the lower end of the plate portion 20 is inserted into the holes P2, and in the contact 8 with a carrier, the middle of the bridge terminal is inserted into the holes P2 and P1, respectively.

[Effects of the Invention] As can be seen from the above description, the bridged contact of the present invention has terminals, etc. simply extending in the vertical direction centering on the holding part, and the terminals and the bridges are mutually used. Because there is
It has a simple structure and the punching work is easy.
It is possible to provide a contact with a carrier that has excellent material removal.
