Abstract

The utility model provides an electric connector with simple structure which can improve the dense degree of terminals, which comprises an insulator and a plurality of terminals arranged in the insulator, wherein the terminals are provided with a main body which is extended upward to separate two arms, and a resilient arm which is extended on the longitudinal direction of the main body and can be traversed into a groove formed by the two arms when the resilient arm is compressed. Compared with the prior art, the utility model is simple in structure, which can improve the dense degree of terminals.

Description

Electric connector

[technical field]

The utility model is about a kind of electric connector.

[background technology]

The patent No. is that the United States Patent (USP) of US6296495 has disclosed a kind of electric connector, its terminal 5 is stamped to form by metal material belt, it is provided with a horizontal welding base 50 to see also Fig. 1, is used for solder terminal 5 to circuit board (not indicating), thereby electrically connects terminal 5 and circuit board.This base portion 50 comprises a rearward end 501 and a leading section 503.Along lengthwise, extend an elastic arm 52 from the rearward end 501 of base portion 50 to the front upper place, this elastic arm 52 by one can with the electric connection of planar grid array chip module and circuit board.Make progress from the leading section 503 of base portion 50, extend a junction 54 forward, it extends a tabular holding parts 56 from front end, and holding parts 56 top bifurcateds also are provided with two fixing arms 561, and the both sides that holding parts is relative are provided with and are used for fixing a plurality of protruding thorn 562 of terminal 5 in insulating body (not indicating) again.But the base portion 50 of this kind terminal 5 and elastic arm 52 form along horizontal expansion substantially, and the horizontal space that so just makes terminal occupy on electric connector is unfavorable for the densification of terminal more greatly.

Therefore, be necessary to design a kind of novel electric connector to overcome above-mentioned defective.

[summary of the invention]

The purpose of this utility model is to provide a kind of densification degree that can improve terminal, and electric connector simple in structure.

In order to achieve the above object, electric connector comprises insulator, and be located in plurality of terminals in this insulator, this terminal is provided with a main part and an elastic arm, this main part extends upward and is formed with two support arms that are separated from each other, described elastic arm extends to form along the longitudinally of main part substantially, is formed with a notch between described two support arms, can pass this notch behind this elastic arm pressurized.

Compared with prior art, the densification degree that can improve terminal simple in structure of the utility model electric connector terminal.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

See also Fig. 2 to Fig. 8, electric connector of the present utility model comprises some insulators 1 and is located in terminal 2 in the insulator 1 respectively.

Described insulator 1 is seen almost parallel quadrangle shape from the side, comprises diapire 10, rear wall 11, and sidewall 12, three walls form terminal accommodating space 13 jointly.Wherein, described diapire 10 offers a socket 100 that runs through diapire 10 downwards, this socket 100 passes to weld with circuit board (not icon) for described terminal 2, in addition, inwardly dig from the lower surface of this diapire 10 and to be provided with a tin ball 3 holding slots 101, described sidewall 12 tops offer a terminal and support only breach 120, are used for to not-go-end 2, in order to avoid terminal 2 excessively moves down.

Described terminal 2 mainly comprises the elastic arm 21 that a main part 20 and autonomous body extend to form.Wherein, the top of described main part 20 extends to form two support arms 200 that separate mutually straight up from both sides, the art end of this support arm 200 is used to connect strip, and be formed with a notch 201 between two support arms 200, behind described elastic arm 21 pressurizeds, pass this notch 201, the side of this support arm 200 convexes with a stop section 202, hold mutually in order to end breach 120 with supporting of insulator 1, in order to avoid terminal 2 excessively moves down, in addition, the middle part of described main part 20 lower edges has extended to form a junction 203 straight down, this junction 203 and circuit board plate (not icon) surface soldered, to realize that terminal 2 is connected with the electric shape of circuit board, need to prove especially, described junction 203 does not directly contact with the tin ball 3 that places described insulator 1 tin ball 3 holding slots 101, up to tin ball 3 heat fused just are dropped on this junction 203, the both sides lower edge bending extension of described upper body 20 forms two bends 210, this two bend 210 is positioned at the both sides of described junction 203, and this two bend 210 is linked to each other by a junction 211, described elastic arm 21 promptly from this connecting portion 211 along lengthwise to, extend upward formation; The end bending of described elastic arm 21 has extended to form a contact site 212, in order to the Elastic Contact chip module.

During assembling, terminal 2 is placed the terminal accommodating space 13 of insulator 1, make the stop section 202 of terminal 2 fasten the lower edge that ends breach 120 that supports in described insulator, the junction of terminal 2 passes described socket 100, so that electric connector is welded on the circuit board plate.
