Embodiment Construction

[0022] Such as Figure 1 ~ Figure 4 As shown, a connector of the present invention includes a hollow pin 10 inside and a sleeve 20 used in conjunction with the pin 10. The pin 10 is provided with a rod 11, and the sleeve 20 is An insertion hole 21 is provided, and the pin 10 is formed by one-time stamping and deep drawing of a brass sheet material. The ratio of the diameter of the pin 10 to the diameter of the brass sheet material is greater than that of the brass sheet material. The ultimate drawing coefficient of the material. As a further improvement of the present invention, the pin 10 may be stepped. At this time, the ratio of the smallest step diameter to the diameter of the brass sheet material is greater than the limit drawing coefficient of the brass sheet material. Wherein, the brass sheet material may be H62 brass or H68 brass. The ultimate drawing coefficient of H62 brass is 0.52~0.54, and the limiting drawing coefficient of H68 brass is 0.50~0.52. When the relat...

Abstract

The invention discloses a connector. The connector comprises a pin (10) having an internal hollow structure, and a pin sleeve (20) used together with the pin (10), wherein the pin (10) is provided with an inserting rod (11); the pin sleeve (20) is provided with an inserting hole (21); the pin (10) is molded from a metal flaky material through one-step stamping and drawing; the ratio of the diameter of the pin (10) to the diameter of the metal flaky material is greater than the extreme drawing coefficient of the metal flaky material. The pin molded through one-step stamping and drawing does not need to be added with other auxiliary materials, has high strength, rigidity and current conducting performance, and is convenient to process. The production efficiency is increased, and the production cost is reduced.

Description

technical field [0001] The invention relates to an electrical connection device, in particular to a connector. Background technique [0002] The connector is a device that connects two active devices. It builds a communication bridge between blocked or isolated circuits in the circuit, transmits current or signals, and enables the circuit to achieve a predetermined function. The processing of connectors has been changed from the traditional process of turning solid bars on a lathe to a new process of punching, such as a utility model patent: a French plug (authorized announcement number CN201259948Y, authorized announcement date June 17, 2009 ) discloses the following technical scheme: comprising a cylindrical pin, colloid and grounding shrapnel, the grounding shrapnel is assembled on the colloid, the colloid includes an external colloid and a filling colloid that are integrally formed by injection molding, and the external colloid and the pin are closely combined by injecti...
