Abstract

The utility model provides a card edge connector, comprising an insulating body, a plurality of terminals, and two metallic sheaths. The insulating body is provided with a body and two side frames. The terminals are arranged on the main body of the insulating body. The two metallic sheaths are respectively arranged on the free ends of the two side frames of the insulating body. Each metallic sheath is provided with a base which extends to the two side frames and forms a limit body, and extends to the outer side faces of the two side frames and forms an elastic arm. The free ends of the elastic arms extend to the two limit bodies and form shielding pieces. When the two side frames are subjected to external force to trigger outward, the two side frames can respectively push the elastic arms to oscillate outward, which enables the shielding pieces of the free ends of the elastic arms to outward displace and contact to the limit bodies to position for limiting the outward stroke of the two side frames, which enables the two side frames not to excessively trigger outward.

Description

Bayonet connector

Technical field

The utility model is about a kind of bayonet connector, refer to especially a kind of can be in order to being arranged on the female circuit board, and can plant for a sub-circuit board, make sub-circuit board and female circuit board realize the bayonet connector of electric connection.

Background technology

See also Fig. 1 and Fig. 2, its announcement has a kind of existing bayonet connector, this bayonet connector can be in order to be arranged at the upper surface of a female circuit board, and this bayonet connector also can be planted for a sub-circuit board, makes sub-circuit board realize electrically connecting by bayonet connector and female circuit board.

This bayonet connector includes an insulating body 91, a plurality of terminal 92 and two metallic sheaths 93 and constitutes, and this insulating body 91 has a main body 911 and left and right two bogie side frames 912 constitute.These terminals 92 are arranged on the main body 911 of this insulating body 91, and the pin portion 921 of these terminals 92 can be welded in the electrical contact of female circuit board, make this bayonet connector and this mother's circuit board realize electrically connecting.When sub-circuit board was inserted between two bogie side frames 912 of this insulating body 91, this sub-circuit board can be realized electrically connecting with these terminals 92.Free end in this two bogie side frame 912 respectively is formed with a lock catch arm 913 in addition, can pass through these two lock catch arms, 913 elastic lock sub-circuit boards.

This two metallic sheath 93 is arranged on two bogie side frames 912 of this insulating body 91.This two metallic sheath 93 is made with metal material, and it respectively has a body 931, and this body 931 is " ㄈ " type body, so that on the sheathed bogie side frame 912 that is matched with this insulating body 91.Body 931 bottoms of this metallic sheath 93 also extend to form a restriction body 932 that projects upwards forward, can utilize the sidewall of this body 931 and this restriction body 932 outwards to reach inside stroke in order to limit two bogie side frames 912 respectively.

Yet, above-mentioned existing bayonet connector, because its metallic sheath 93 is a rubber-like elongated body, therefore when taking out sub-circuit board, two bogie side frames 912 are outwards pulled, when this lock catch arm 913 is broken away from sub-circuit board, the stroke that restriction that the sidewall of the body 931 of this metallic sheath 93 can not be certain two bogie side frames 912 are outside, therefore two bogie side frames 912 have and outwards pull excessive possibility, and then cause the situation generation that deforms or rupture with two bogie side frames 912 that plastic material is made.

In summary, the bayonet connector of described prior art on reality is used, obviously exists inconvenience and defective, so be necessary to be improved.

Summary of the invention

At above-mentioned defective, main purpose of the present utility model, being to provide a kind of bayonet connector, can be when two bogie side frames be outwards pulled, the function of block location is provided, in order to the outside stroke of certain restriction two bogie side frames, two bogie side frames are not had outwards pull excessive possibility, and the situation of distortion of two bogie side frames or fracture that can effectively prevent takes place.

In order to realize above-mentioned purpose, the utility model provides a kind of bayonet connector, comprising: an insulating body, and it has a main body and two bogie side frames; A plurality of terminals are arranged on the main body of this insulating body; Two metallic sheaths, be arranged at the free end of two bogie side frames of this insulating body respectively, each metallic sheath has a base portion, this base portion is toward having extended to form a restriction body between above-mentioned two bogie side frames, and the lateral surface along two bogie side frames has extended to form an elastic arm, and this free end of elastic arm has extended to form a retaining piece toward between above-mentioned two restriction bodies; And above-mentioned two bogie side frames are subjected to external force and when outwards pulling, and this two bogie side frame can be distinguished the pushing tow elastic arm and outwards swings, and the retaining piece that makes this free end of elastic arm contacts at the restriction body and locatees to outer displacement, in order to limit the outside stroke of two bogie side frames.
