ズが長官１．２５Ｃｒｎ、直径０．１５ｃｒｎと小さい
ため深刻に々る。Due to the large number of contacts used in connectors, stamped contacts are increasingly being used. This is because the cost is lower than when machining metal materials. However, although the cost is low, the punched and formed contacts have low strength and durability because they are made of thin metal sheets. For example, the retaining spring of a socket-shaped contact manufactured by stamping is more likely to deform than that of a machined contact. Therefore, when a pin-shaped contact is inserted into the presser spring portion, the spring pressure becomes weaker and the electrical resistance between the inserted contacts increases, which is an undesirable result. Moreover, since the strength of the stamped inner tube is weak, a protective tube is required around the rear portion to which the external conductor is connected and around the engaging portion. This not only increases the time required to make the contacts, but also increases the cost of materials. This problem is especially serious in the case of micro-miniature electrical connectors because the contact size is as small as 1.25 crn in length and 0.15 crn in diameter.
本発明は超小型電気コネクタ用の接点アッセンブリを提
供するもので、ソケット形接点部材を冷間引抜きしその
部材の突端部分に保護管を付けたことを特徴とする。The present invention provides a contact assembly for a micro-miniature electrical connector, which is characterized in that a socket-shaped contact member is cold-drawn and a protective tube is attached to the tip of the member.
本発明の利点は、機械加工した接点より低コストで、打
ち抜き成形した接点より強度の高い接点を提供できる点
である。An advantage of the present invention is that it provides a contact that is less costly than machined contacts and stronger than stamped and formed contacts.
本発明の他の利点としては、引込線を接続する部分に保
護管を付ける必要がない点が挙げられる。Another advantage of the present invention is that there is no need to attach a protection tube to the part where the service line is connected.
同じく他の利点として、超小型コネクタ用の接点受収部
となる押さえバネの強度が増し、それにより接点挿入時
の（摩擦）抵抗の減衰を防ぐ点が挙げられる。Another advantage is that the strength of the hold-down spring, which serves as a contact receiving part for micro-miniature connectors, is increased, thereby preventing the (frictional) resistance from decaying during contact insertion.

に示した接点アッセンブリ３０の一部裁断図である。FIG. 1 shows a cold drawn tubular member 10 having a pointed end including a plurality of hold-down springs 12 forming socket-type contacts. This tube member 10 is made of a metal such as a copper alloy, and is provided with an annular groove 13 that cooperates with a mechanism (not shown) for holding contacts at a connector insertion portion. FIG. 2 shows a tube 20 that protects the tip of the tube member 10 shown in FIG. FIG. 3 shows a contact assembly 30 in which the protective tube 20 is attached to the tip of the tubular member 10. FIG. 4 is a partially cutaway view of the contact assembly 30 shown in FIG.

(not shown) gives elasticity to the fingers 12, allowing the protective tube 20 to be attached around the front end of the tubular member 10, and recesses 21 are provided at several locations on the protective tube. This allows for locking with the pipe member.
