Description

Electric connector

[technical field]

The utility model relates to a kind of electric connector, refers to a kind of electric connector that chip module is electrically connected to printed circuit board (PCB) especially.

[background technology]

Figure 1 shows that a kind of electric connector of the prior art relevant with the utility model, its announcement has two elastic arms, and this elastic arm is assembled on the insulating body.After chip module installed to insulating body, elastic arm produced chip module and supports effect, with this chip module is held in the insulating body, drops out in order to avoid chip module moves because of the upset of insulating body.

But the insulating body that is assembled with elastic arm can increase assembling procedure, makes the manufacturing cost of electric connector increase, and reduces this competitiveness of product in market, is unfavorable for the popularization of this product.

Therefore, be necessary to provide a kind of improved electric connector, to overcome the defective of aforementioned electric connector.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector simple in structure that holds chip module.

The utility model is achieved through the following technical solutions: a kind of electric connector, be used to accept chip module, comprise conducting terminal and insulating body, insulating body is provided with the rectangle continuing surface that is used to accept chip module, above-mentioned conducting terminal is contained in the continuing surface place of insulating body, be arranged with sidewall on the surrounding of continuing surface, the common formation of sidewall and continuing surface is accommodated the host cavity of chip module, and the definition sidewall is a madial wall towards a side of host cavity, wherein, described madial wall is provided with and the integrated blocked block of insulating body, and blocked block is provided with the fin with said chip module interference engagement.

Compared with prior art, the utlity model has following beneficial effect: blocked block and insulating body are one-body molded, reduce production costs, and reduce assembling procedure, help improving product competitiveness.

[embodiment]

See also Fig. 2 to shown in Figure 4, the utility model is a kind of electric connector that electrically connects of reaching between chip module 1 and the printed circuit board (PCB) (not icon), and it comprises insulating body 2, be contained in the plurality of conductive terminals 3 in the insulating body 2 and chip module 1 is held in fastener (not shown) on the insulating body 2.

Chip module 1 is block rectangle, and the side 12 that includes main part 11 and surround main part 11 wherein respectively is provided with a breach 120 on two opposed side edges 12.

Insulating body 2 rectangular shapes, it is provided with the continuing surface 21 of accepting chip module 1.The bottom of insulating body 2 offers plurality of terminals accepting groove (not label), and conducting terminal 3 is contained in the respective terminal accepting groove.Only show wherein part terminal containing slot and conducting terminal among Fig. 2.The edge of the continuing surface 21 of above-mentioned insulating body 2 also is provided with upwardly extending sidewall 22, this sidewall 22 is set as the host cavity (not label) of accommodating chip module 1 with continuing surface 21 one common peripheral, wherein sidewall 22 is called madial wall 220 towards a side of host cavity.Describedly wherein be respectively equipped with projection 222 on the two relative madial walls 220, this projection 222 can cooperate with corresponding breach 120 on the chip module 1, plays a part to discern and cooperate.Chip module 1 is contained in behind the host cavity to reach by conducting terminal 3 and printed circuit board (PCB) and electrically conducts.

Also be provided with blocked block 221 on the madial wall 220 of insulating body 2.Blocked block 221 is distributed in the place, contiguous diagonal angle of the madial wall 220 that links to each other, and is provided with eight blocked blocks 221 altogether.Blocked block 221 is provided with fin 223 towards a side of host cavity, and fin 223 extends along the direction perpendicular to continuing surface 21.The cross section of fin 223 is triangular in shape, and the summit is towards host cavity.This blocked block 221 is formed in one with insulating body 2.

See also shown in Figure 4ly, chip module 1 is assembled to behind the host cavity its side 12 interferes with blocked block 221 and supports, by the side 12 of the fin 223 extruding chip modules 1 of blocked block 221, chip module 1 stable being contained in the insulating body 2.Triangular in shape and summit is towards host cavity because of the cross section of fin 223, the side 12 of chip module 1 and fin 223 like this, are assembled into chip module 1 in the host cavity easily for line contacts, and the line contact matching makes between the two and to cooperate closely, can the gap not appear in the cooperation place and make cooperate unstable.

In the practical application, blocked block 221 can suitably be adjusted quantity according to application demand.It can be separately set on the madial wall 220, also can be arranged on two adjacent or opposed inside walls 220, can also be arranged at certainly on three madial walls 220 wherein.
