Electric connector module and its producing process

Abstract

The invention discloses an electrical connector assembly and its manufacturing process. The electrical connector assembly has a body and terminals accommodated therein, wherein the body has a mating surface and a mating groove opened from the mating surface, and the terminal has a mating groove accommodated in the mating groove. The contact part and the tail part extending from the contact part, the tail part is provided with thorns which gradually become thicker along the direction of the contact part, and a pulling part is extended. The main steps of the manufacturing process of the electric connector assembly are to insert the terminal into the matching groove from the mating surface, and then pull it in and position it by the pulling part.

Description

【Technical field】 [0001] The invention relates to an electrical connector assembly electrically connected to a circuit board and a manufacturing process of the electrical connector assembly. 【Background technique】 [0002] As mentioned on page 1737, page 1755 of "Proceedings of 1990 National Electronic Packaging and Production Conference (NEPCON WEST'90)" (V01.2), board-to-board electrical connector assemblies are widely used in various electrical equipment to connect two separate circuit board. As disclosed in U.S. Patent Nos. 5,639,248, 5,641,290, 5,928,003, and 5,556,286, issued June 17, 1997, June 24, 1997, July 27, 1999, and September 17, 1996, respectively, board-to-board electrical The connector assembly is assembled with the circuit board by its terminals being fixed to the circuit board. Taiwan Patent Announcement No. 330349 published on April 21, 1998 discloses a method of assembly of terminals and connector bodies. The terminals are inserted into the terminal ac...

Problems solved by technology

Taiwan Patent Announcement No. 330349 published on April 21, 1998 discloses a method of assembly of terminals and connector bodies. The terminals are inserted into the terminal accommodation holes from the joint surface of the connector body close to the circuit board, and the terminal The thorns on the wall interfere with the inner wall of the terminal accommodating hole of the connector body for positioning. This type of assembly is more clearly shown in Figure 6A and Figure 6B , the protrusion 81 of the terminal 8 must be designed to gradually become thinner along the insertion direction to complete the assembly, but the arrangement of the protrusion 81 makes the interference force between the terminal 8 and the terminal accommodating hole 9 separate along the mating connector The direction of driving the connector body decreases gradually, so it is easy to cause the connector body and terminal 8 to be inadvertently disengaged when the docking connector is separated, and the stable assembly of the connector component and the circuit board cannot be guaranteed.

[0003] And if using as Figure 7 As shown, the method of inserting the terminal 6 into the terminal accommodating hole 53 by applying pressure from the mating surface 52 opposite to the joint surface 51 will easily deform the contact portion 62 of the terminal 6, resulting in poor contact with the mating connector.
