Abstract

PURPOSE: To improve productivity by having a pair of legs and a bridge part and narrower than the size of a pin at a part extending from the bridge part, and narrowing near a free end to have elastic deviation for contact with the pin. CONSTITUTION: Crank parts 16, 17 facing the outside and crank parts 18, 19 facing the inside are formed at leg parts 13, 14. The leg parts 13, 14 are shaped so that a leg part gap is maximized at an end part close to a bridge part 15 and the gap is reduced when these leg parts approaches a free end. Crank members 20, 21 facing the outside are formed to easily accommodate a pin at the free end therein. A block 30 is provided with a passage 31, from one end of which an insulation removing part 12 is extruded, and from the other end of which a pin 32 is engaged. Since the bridge part 15 is small in size, a passage 31 can be small-sized. Ribs 33, 34 are provided inside a leg part free end in the passage 31, and the pin 31 can be prevented from being hardly inserted as the result of the excessive approaching of the leg parts at a narrow interval part.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to contacts, and more particularly to contacts for use in multi-contact socket bodies that cooperate with multi-pin male connector elements.

[Problems to be solved] In multi-pin contacts, the pin spacing is narrow, typically 2.54 mrn for pin size 0.6:15 nn m, 8 spacing L54 mm, iE square with -side 0.535 mm. It is problematic to stamp out a socket contact large enough to accommodate a pin from a sheet material using a hollow tool.

This problem exists even with other sizes and intervals.

Some clever solutions have been proposed so far. A convenient solution for U-shaped sockets with evenly spaced contact arms is to make the socket spacing larger than the pin spacing in order to provide the proper socket size for pin accommodation; The holes are punched out at twice the pin spacing. As a result, in order to obtain the desired spacing ψ, the socket row must be inserted into the connector body twice.

[F1 Stage for Solving Problems] According to the present invention, the following socket contact is proposed. That is, in a socket contact that includes a socket part that accommodates a pin during use and a bond end part that makes a connection with a conductor, etc., and that can be formed after punching out a planar material, this socket part: You can engage the pin in between when using it!
``a pair of legs facing each other and a bridge connecting the legs at a distance from their free ends, the bridge being substantially U-shaped, Where they extend, the spacing between the legs is narrower than the size of the pin to be accommodated by the socket; furthermore, the leg spacing is greatest near the ends that are joined by the bridge, and the free ends + -i The socket contact has a crank shape in which the distance between the legs is narrow in order to make contact with the pin so as to bias it elastically during use.

The free ends of the legs can also be formed to open away from each other to facilitate insertion of the pin in use.

These legs may also be gold coated in closely spaced areas.

Furthermore, the terminal end of the contact may be formed by an insulation removal type contact.

According to the invention, the male connector is further punched out of a one-sided material and is connected by a portion of the one-sided material before being inserted into the female connector block so that the female connector mates with the male connector during use. A series of socket contacts are provided with spacing that matches the pin spacing of the connector. .

According to another feature of the present invention, the following planar material is provided. l]ll, a stamped planar material of electrically conductive material suitable for forming a series of contacts for use in female connectors, a plurality of flat contact sections attached thereto alongside an elongated bubble seal; and each contact portion has a bridge portion and a pair of legs extending from the bridge portion and formed into the contact, and the spacing between the contact portions is such that the distance between the female connector and the mating portion is determined in use. This is a punched sheet material that matches the pin spacing of the male connector.

Also provided in accordance with the present invention is a method of forming a socket contact. That is, in a method for forming socket contacts that are inserted into a female connector block at intervals that match the pin spacing of opposing male connectors, a plurality of contact sections are connected by a part of the sheet material, and each contact section is connected by a portion of the planar material. a step of punching out a flat plate contact portion from the flat planar material so as to have a bridge portion and a pair of legs extending therefrom; and a step of bending the bridge portion of each contact portion into a U-shape. The method of forming a socket terminal includes the step of cranking the legs to maximize and reduce the spacing between the legs.

This method may include a step of coating the legs with gold at one narrow space after the punching step 1 and before the forming into the final shape (step 2).

A method is also provided which includes the step of inserting contacts formed in accordance with the present invention into a female connector block at intervals of the sockets or pins to be mated.

The insertion step preferably includes a step of inserting the contacts connected by a part of the planar material and removing the part of the planar material after insertion.

For purposes of illustration, an embodiment of a socket contact according to the invention and a method of manufacturing the same will be described with reference to the drawings.

EXAMPLE FIG. 1 shows a series of contacts IO stamped from sheet conductive material, it being understood that each contact 10 may have an insulation removal 12 or may have other types of terminations. . Each contact 10 has a pair of legs 13 , 14 connected by a bridge 15 .

The length of the bridge portion 15 is determined by the length of the leg portion 13 when the leg portion 11.14 is essentially flat and the bridge portion 15 is bent into a U-shape.
．． The 11!1 spacing of 14 is chosen to be substantially smaller than the size required to accommodate, for example, 0.635 mm pins used in MηI connectors. The interval at which the contacts 10 are punched out is the interval generally used for connectors, that is, 2.5 mm.
4 mm, this is achieved by shortening the bridge 15 of the contact IO.

Following stamping, the bridge and legs are formed into the final contact shape shown in FIG. From FIG. 2, it will be clear how small the bridge section 15 becomes when folded into a U-shape. Part 18, 1
．． 9 is formed.

As a result, the legs 13 and 14 are shaped such that the distance between the legs is maximum at the end near the bridge portion 15, and becomes smaller as the distance approaches the free end. The free end of the leg 13.14 is formed with an outwardly facing crank portion 20.21 to facilitate the accommodation of the pin in use.

It is also possible to gild the legs 13, 14 (near the free ends of the legs 13, 14, where the distance between the legs eventually becomes smaller) before forming the shape shown in FIG. Since the forming process is in-process, gold plating can be done after punching.

FIG. 3 shows a contact 10 disposed in a female connector block 30. The block 30 has a passageway 3, from one end of which an insulation removal part 12 protrudes, and from the other end a pin 32 fits. Since the bridging portion 15 is small, there is an advantage that the passage 1 can be made smaller on the side closer to the bridging portion 15.

Ribs]: l, 34 are provided on the inside of the free ends of the legs 13, 14 in the passage 31, and the legs 13, 14 are provided in narrowly spaced parts.
It functions as a stopper to prevent the pin 32 from coming too close to the tail and making it difficult to insert the pin 32.

It is clear from FIG. 3 how the pin 32 is substantially larger than the U-shaped bridge 15 and how the crank shape of the legs 13.14 facilitates the insertion of the pin 32 between the free ends of the legs. Will.

[Effect 1: By making the contacts in this shape, the spacing between the contacts on the punching surface can be made extremely small, and since the socket contacts can accommodate standard-sized pins, they can be punched with a spacing of 2.54 mm. Moreover, no complicated metal loading is required to make it a practical device. The leg shape forming process only involves simple work, so before this forming process,
The gold coating can be carried out while the series of contacts is also held together and not separated into pieces.

In the prior art, in which the sockets were formed with a spacing twice the pin spacing, two insertions were required, but in the invention, the socket spacing is the same as the pin spacing, so each socket row is
It is inserted in one operation.

It should be understood that the foregoing description is intended to be illustrative only, and that improvements and modifications can be made within the scope of the spirit of the present invention.
