Embodiment

[0018] Example: such as Figure 5 As shown, an electrical connector with fixed contacts includes a housing 4 , an upper base 2 , a lower base 3 and a contact 1 .

[0019] Such as figure 2 , image 3 , Figure 4 As shown, the contact piece 1 is provided with a radial limit portion 11 , an interference portion 12 , a tapered portion 13 and a guide portion 14 . The contact piece 1 is fixed by clearance fit or transition fit with the upper base 2 through the radial limit portion 11, and the interference fit portion 12 is fixed with the lower base 3, so that the contact piece 1 is installed and fastened, and the contact piece 1 does not shake. The lower part of the interference part 12 is provided with a guide part 14 which acts as a guide to facilitate the assembly of the contact piece 1 and the base. The cylindrical diameter of the guide part 14 is smaller than that of the interference part 12; There is a conical surface 13 for connecting the cylindrical surface of the inter...

Abstract

The invention discloses an electric connector fixed by a contact element, which comprises an outer casing (4), an upper base (2), a lower base (3) and a contact element (1), wherein a radial limiting portion (11), an interference portion (12) and a guiding portion (14) are arranged on the contact element (1), the contact element (1) is in clearance fit or transitional fit fixing with the upper base (2), the interference portion (12) is in interference fit fixing with the lower base (3), the lower portion of the interference portion (12) is equipped with the guiding portion which has guiding functions and is convenient for assembly of the contact element (1) and the base, and the outer diameter of the guiding portion (14) is smaller than that of the interference portion (12). A conical surface portion (13) for connecting the cylindrical surface of the interference portion (12) and the cylindrical surface of the guiding portion (14) is arranged between the interference portion (12) and the guiding portion (14). The contact element is closely engaged with the bases, is stable in installation, can effectively resolve the shaking problem of the contact element, and is convenient to assemble and high in assembly efficiency.

Description

technical field [0001] The invention relates to an electrical connector, in particular to an electrical connector with fixed contacts. Background technique [0002] Usually in the connector, the structure of the fixed contact is as follows: figure 1 As shown, it includes: contacts, upper base, lower base and housing. Wherein, the contact piece has a radial limiting portion and an axial limiting portion. The contact piece is fixed by the upper base and the lower base. The radial limit part of the contact piece adopts clearance fit or transition fit with the upper base instead of interference fit. The reason is that the interference fit makes the assembly of the connector very difficult and easily causes problems such as deformation and damage of the contact piece; the contact piece The axial limit part of the upper base adopts clearance fit with the lower base. [0003] With the trend of miniaturization and flattening of connectors, the upper and lower bases of the connec...
