Abstract

The utility model relates to an electric connector, which comprises an insulated body, and two sides are provided with fastening devices. Each fastening device comprises a resin element and a metal element which is integrally extended from the insulated body. A first hanging wall of the metal element is adjacent to the outer surface of the resin element, a first inserting foot is extended, and the first inserting foot and the first hanging wall together limit the resin element. A second inserting foot is extended from the position of the first hanging wall adjacent to the resin element. When the fastening devices are positioned on the furthest positions, the excessive deformation and even breaking of the resin element are prevented. A third inserting foot is extended from the lower side of the first hanging wall to be accepted in a concave opening of the outer surface of the resin element to limit the inward displacement of the fastening devices, and the breaking of the resin element is further prevented.

Description

Electric connector

The utility model is a kind of electric connector, and it has a bayonet unit, and this bayonet unit includes a resin components that is fitted to each other and a hardware, is housed in module group unit in the electric connector with the taking-up of safety.

United States Patent (USP) the 5th, 759,057 and 5,755, disclosed a kind of electric connector (Small OutlineDual In-line Memory Modules, SO DIMM) for No. 585, wherein the 5th, 759, No. 057 case has disclosed a kind of bayonet unit, and it is made of a resin components and a hardware, and the 5th, 755, No. 585 cases have disclosed a kind of design of high configuration.

Integrated resin components is used for the shearing recess of fixing module group unit, and hardware is used in takes out module group unit from resin components.Wherein hardware can be separated from insulating body.But although bayonet unit provides certain elasticity and intensity, resin components still is easy to be subjected to improper external force and ruptures.

In order to prevent that resin components from rupturing, insulating body provides stop section moving with the restriction resin components.This has increased the length of electric connector inevitably, limited the raising of electronic component closeness, in addition, the durability of resin stop section is relatively poor, thereby has hindered the Flexible Design of resin components, and, when fastening or take out module group unit, hybrid-type bayonet unit is pushed away its initial position, and resin components is everlasting in this process, because of the stress of being concentrated ruptures at the joint of resin components and insulating body, and joint is the flexure plane of a place without any reinforcement.

Because connector designs forr a short time than prior art at lengthwise to need, the structure that is disclosed more than the event all need be improved, wherein the insulating body of electric connector can not change, because it need be consistent with the circuit arrangement of the module group unit that inserts, therefore, the size that reduces the bayonet unit of insulating body both sides is an only way, thereby realizes miniaturization and overcome the prior art defective.

The purpose of this utility model provides a kind of electric connector with bayonet unit, and it has preferable elasticity, is convenient to be assembled on the electric connector insulating body, to strengthen the danger of bayonet unit to reduce to rupture.

The utility model comprises that one is the insulating body of lengthwise body shape, be provided with a central slot in it to accept module group unit, the insulating body both sides are provided with bayonet unit, each bayonet unit includes a resin components and the hardware corresponding to resin components that extends from the insulating body one, the first vertical wall of hardware is adjacent to the outer surface of resin components, and hang down first pin that wall extends with the restriction resin components from first, applying external force at the free end of bayonet unit can make module group unit take out from electric connector, second pin is from the first vertical wall extension and in abutting connection with resin components, when bayonet unit arrives its outermost position, can prevent excessive deformation and cause fracture, the 3rd pin extends with the recess that is housed in the resin components outer surface from the first vertical wall below, and the resin components that moves inward and further prevent of restriction bayonet unit ruptures.

Compare prior art, the utility model can limit the over-travel of bayonet unit and cause fracture, and can impel the miniaturization of electric connector.

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

Fig. 2 three-dimensional combination figure of the present utility model.

The three-dimensional exploded view of Fig. 3 bayonet unit of the present utility model.

The three-dimensional combination figure of Fig. 4 bayonet unit of the present utility model

See also Fig. 1, the utility model comprises the insulating body 12 that is the lengthwise shape, on insulating body 12, be provided with central slot 14 to accommodate module group unit (not shown), opposite side at the central relatively slot 14 of insulating body 12 is provided with the conducting terminal (not shown) of several terminal channels 16 to accommodate respective number, wherein, conducting terminal can electrically be connected corresponding circuit on the module group unit with mechanicalness.

See also Fig. 2, bayonet unit 18 is located at the both sides of insulating body 12, and each bayonet unit 18 includes a resin components 20 and the hardware 22 corresponding to resin components 20 from the extension of insulating body 12 one.

See also Fig. 3, resin components 20 comprises a upper arm 202 and a underarm 204, and locked body 206 is located at the inner surface of upper arm 202, and recess 208 is located at the outer surface of underarm 204 free terminals, and is provided with groove 210 in underarm 204.

Hardware 22 comprises first vertical wall 26, the second vertical wall 28, be provided with hangnail 30 at second vertical wall 28 front ends, and the first vertical wall 26 and the second vertical wall 28 is not in the same plane, and is provided with dislocation 32 between the two.

Horizontal bends 34 is hung down the extension of wall 26 bottoms to strengthen the first vertical wall 26 from first, be provided with first pin 36 and extend upward from horizontal bends 34, second pin 38 that slightly is " L " type has a by-level portion 382 and a terminal vertical component effect 384 that extends from first vertical wall 26 bases, extend and be provided with the 3rd pin 40, the second walls 28 that hang down and extend forward from its terminal connecting portion 44 and be provided with weld pad 42 from first wall 26 that hangs down 38 of horizontal bends 34 and second pins.

See also Fig. 3 and Fig. 4, the utility model is when combination, and hardware 22 engages by the second vertical wall 28 is inserted in the grooves 210 with resin components 20, and the interference effect of hangnail 30 can make hardware 22 be retained in the insulating body 12.First wall 26 that hangs down matches in abutting connection with the outer surface of upper arm 202 and with first pin 36 and is housed in the recess 208 with 40 of clamping resin components 20, the three pins betwixt.42 of weld pads are aligned with the weld pad of the circuit board (not shown) of assembling the utility model 10.

When module group unit was inserted into electric connector 10, module group unit was by locked body 206 clampings, and when external force was applied to the free end of bayonet unit 18, locked body 206 can unclamp, and module group unit can be taken out from electric connector 10.Because second pin 38 is in abutting connection with underarm 204, so when bayonet unit 18 arrives its most external position, second pin 38 can prevent its excessive deformation and and then prevent bayonet unit 18 fracture, 40 restrictions of the 3rd pin bayonet unit 18 to internal strain further to prevent its fracture.

According to above-mentioned feature, the 3rd pin 40 excessively outwards is out of shape to prevent resin components 20 corresponding to underarm 204, in addition, second pin 38 can prevent also that corresponding to underarm 204 resin components 20 is excessively to internal strain, therefore, the displacement that the utility model 10 can be guaranteed resin components 20 outside all in the scope of a safety, rather than only concentrates on the improvement of outside distortion interior in the prior art.
