Description

Electric connector

Technical field

The utility model relates to a kind of electric connector, particularly a kind of electric connector with metal shell and insulating base frame.

Background technology

Consult Fig. 1, Fig. 2 and Fig. 3, existing electric connector includes: an insulating base frame 10, and it is a plastic cement material, and its front end central authorities are provided with protuberance 11, and its both sides respectively are provided with a draw-in groove 12 and a perforation 13, and its internal arrangement is provided with a plurality of terminals 14; One metal shell 20, its central authorities are provided with protuberance 21 and use the protuberance 11 that is linked in these insulating base frame 10 front ends, and its both sides respectively are provided with a perforation 22; Two buckle spares 30 are provided with location division 31 and elastic clamping hook portion 32, and these location division 31 central authorities are provided with a perforation 33, draw-in groove 12 fastenings of this location division 31 and insulating base frame 10, and this elastic clamping hook portion 32 reaches insulating base frame 10 belows; And two rivets 40, it is provided with pressure section 41 and extension 42, this pressure section 41 props up the location division 31 of this buckle spare, this extension 42 pass this buckle spare 30, insulating base frame 10, and metal shell 20 rearward ends strut riveted and be fixed on the metal shell 20, these rivet 40 central authorities are provided with screw 43.

Above-mentioned existing electric connector is to fix with motherboard by buckle spare 30 enhancings of both sides in use, the screw 43 of this rivet 40 can be used the spiral shell spare that is spirally connected, so when being connected, can lock screw, guarantee to be electrically connected, yet above-mentioned existing structure have following shortcoming in the use with another electric connector:

1, the location division 31 of buckle spare 30 does not have the blocking effect with the pressure section 41 of rivet 40, though therefore buckle spare 30 is fixing with the motherboard welding, still can't use and prevent rivet 40 rotations, and mainly being draw-in groove 12 blockings by insulating base frame 10, rivet 40 limits its rotation, yet the blocking effect of plastic cement material is limited, often have because of lock screw tension causes insulating base frame 10 and occur that damaged (present electric connector is for guaranteeing electrical connection, the requirement of twisting resistance more improves, so really lock screw and the situation of insulating base frame breakage can not appear).

2, an end of rivet 40 compresses buckle spare 30, insulating base frame 10, reaches metal shell 20 with pressure section 41, direct and the metal shell riveted of the other end, like this, when electric connector is crossed the WU stove of high temperature and motherboard welding, because the insulating base frame 10 of plastic cement material ruckbildung occurs because of thermal shock, confining force behind the riveted is affected, thereby reduces the twisting resistance effect.

The utility model content

Main purpose of the present utility model provides a kind of electric connector, and it can strengthen the twisting resistance effect, prevents to cause insulating base frame breakage to occur because of lock screw tension.

For achieving the above object, the utility model electric connector includes: an insulating base frame; One metal shell, it is linked in the front end of this insulating base frame; At least one buckle spare, it is provided with location division and elastic clamping hook portion, this location division and insulating base frame fastening, this elastic clamping hook portion reaches the insulating base frame below; And at least one rivet, it is provided with pressure section and extension, this pressure section is compressing the location division of this buckle spare, this extension pass this buckle spare, insulating base frame, and metal shell after riveted fix; The location division that it is characterized in that this buckle spare is provided with projection and forms the pressure section of this rivet of edge clipping fastening of jumps with other positions.

Above-mentioned and other purpose of the present utility model, advantage and feature are by in the following DETAILED DESCRIPTION OF THE PREFERRED and with reference to the accompanying drawings should be more obvious.

Embodiment

Consult Fig. 4 to Fig. 9, they have shown the utility model first preferred embodiment, include an insulating base frame 50, a metal shell 60, two buckle spares 70 and two rivets 80.

Consult Fig. 9, insulating base frame 50 its front end central authorities are provided with protuberance 51, and its both sides respectively are provided with a draw-in groove 52 and a perforation 53, and its inner row is provided with a plurality of terminals 54 (ginseng See Fig. 5), because terminal 54 is not a feature of the present utility model, therefore its structure is not described in detail in detail at this.

It is provided with first 63 and second 64 metal shell 60, and these second 64 central authorities is provided with that protuberance 61 is used cover should the protuberance 51 of insulating base frame 50 front ends, and its both sides respectively are provided with a perforation 62.

Consult Fig. 8, buckle spare 70 is provided with location division 71 and elastic clamping hook portion 72, these location division 71 central authorities are provided with a perforation 73, and its upper end is provided with the edge clipping 74 of projection, this edge clipping 74 forms the recess of a trapezoidal shape and forms a jump with other positions, draw-in groove 52 fastenings of this location division 71 and insulating base frame 50, this elastic clamping hook portion 72 reaches insulating base frame 50 belows.

Rivet 80 is provided with pressure section 81 and extension 82, and its central authorities are provided with screw 85, this pressure section 81 is hexagon, it is compressing the location division 71 of this buckle spare 70 and is being 74 blockings of flange, the lower end of this extension 82 is provided with a clamping face 83 and extends the caulking part 84 that a bore dwindles, this extension 82 passes this buckle spare 70, insulating base frame 50, reaches metal shell 60, its clamping face 83 is connected to first 63 of metal shell 60, and this caulking part 84 struts riveted and is fixed on second 64 of metal shell 60.

Owing to have above structure, electric connector of the present utility model has the following advantages:

1, this rivet 80 when riveted except pushing against with pressure section 81 buckle spare 70 and the insulating base frame 50, and by first 63 clamping of this clamping face 83 with metal shell 60, like this, when electric connector is crossed the WU stove of high temperature and motherboard welding, though insulating base frame 50 has ruckbildung under thermal shock, yet because rivet 80 is direct by clamping face 83 and first 63 clamping packing of metal shell 60, therefore can not be affected, good twisting resistance effect is still arranged because of insulating base frame softening makes the confining force behind the riveted.

2, the pressure section 81 of rivet 80 is subjected to flange 74 blockings of buckle spare 70, like this, after the elastic clamping hook portion 72 of this buckle spare 70 was fixing with the motherboard welding, the pressure section 81 of the flange 74 blocking rivets 80 by metal material can clearly limit rivet and rotate, and therefore can have preferable twisting resistance effect.

Consult Figure 10 to Figure 12, it is second embodiment of the present utility model, and wherein the flange 74 of this buckle spare 70 is located at four jiaos of location division 71, shape slightly triangular in shape, four limits of using the pressure section 81 of blocking rivet 80.

Consult Figure 13 to Figure 15, it is the 3rd embodiment of the present utility model, and wherein the pressure section 81 of this rivet is square, and the flange 74 of this buckle spare 70 is located at four jiaos of location division 71, and is slightly L-shaped, uses the Si Jiaochu of the pressure section 81 of blocking rivet 80.

The specific embodiment that is proposed in DETAILED DESCRIPTION OF THE PREFERRED is only in order to illustrate technical characterictic of the present utility model, and be not with the utility model narrow sense be limited in this embodiment, all many variations of being done in spirit of the present utility model and following claims scope all belong to scope of the present utility model.
