Abstract

The utility model provides a connector structure improvement which comprises a base frame, an outer cover and a terminal seat; wherein, the outer cover stretches toward a side wall with a symmetrical shrapnel and the upper wall is provided with a contact shrapnel, thereby, a negative electrode contacting and touching terminal is formed by the outer cover. The negative electrode contacting and touching terminal contacts the housing case by the shrapnel of the outer cover and the elasticity of the contact elasticity. Moreover, the support part of the outer cover is penetrably provided with the embedded groove part on the base frame, and can strengthen the immobility and robustness between the outer cover and the base frame. Furthermore, the support part of the outer cover is arranged on the circuit board so as to realize the direct contact conduction effect.

Description

Connector construction improves

Technical field

The utility model provides a kind of connector construction to improve, and it is installed in the effect that can reach direct contact conducting on the circuit board.

Background technology

The A of general known connector as Fig. 1, Fig. 2 and shown in Figure 3, is made up of body A1 and contact terminal A2; Lateral margin in body A1 upside is provided with retaining piece A3, wherein retaining piece A3 is provided with screw fixed hole A4, its body A1 down extends and is provided with symmetrical contact terminal A2 again, be located on the circuit board A7 by contact terminal A2 down again, when its connector of installing A, need earlier its retaining piece A3 to be contacted at casing A6, and must utilize the solid A5 of spiral shell again with its casing A6 and body A1 locking, make it form the touching end of negative pole, this installation method too bother and retaining piece A3 on screw fixed hole A4 need offer in addition, waste its cost.

How to address the above problem, promptly be technological difficulties of the present utility model.

Summary of the invention

The purpose of this utility model provides a kind of fastener structures and improves, and can reduce cost, and reaches the effect of direct contact conducting.

The utility model is achieved in that a kind of fastener structures, its housing extends to sidewall and upper wall is provided with symmetrical shell fragment and contact flat spring, by this, its housing utilizes the elastic force of shell fragment itself and contact flat spring and casing to conflict mutually, make it form the touching end of negative pole, moreover the steadiness between its housing and the pedestal is that the camphane ditch portion that the support by housing is fixed on the pedestal realizes.

A kind of connector construction that the utility model provides improves, and as Fig. 5 and shown in Figure 6, it is made up of pedestal C, housing D and terminal pedestal E; The upper wall D4 lateral margin of its housing D is provided with contact flat spring D3 and extends to sidewall D5 by both sides, wherein side walls D5 is provided with symmetrical shell fragment D2, just can conflict mutually with casing by contact flat spring D3 and shell fragment D2, down extend again and be provided with a plurality of symmetrical support D1, wherein support D1 can wear the camphane ditch C1 of portion on the pedestal C and increase its housing D and pedestal C between fastness and steadiness, moreover, its terminal pedestal E is an insulating base frame, and be equiped with a plurality of metal terminal E1, but correspond to circuit board G and conducting by metal terminal E1.

Its pedestal C is the integrated pattern of top base C5, bottom base C6 and side group seat C7, and present the difform fit C4 of portion, wherein the side group seat C7 in pedestal C is provided with and other | the camphane ditch C1 of portion that side is symmetrical, and down extend the pin C2 that is provided with the plural number symmetry in the lower edge of side group seat C7, moreover, top base C5 and bottom base C6 in pedestal C are provided with symmetrical plural shell fragment C3, its shell fragment C3, the camphane ditch C1 of portion and pin C2 are all pedestal C punching out and form, make its low cost of manufacture, and be difficult for causing distortion because of bump.

For making the utility model show progressive and practicality more, to do a comparative analysis as follows with existing structure:

The existing structure shortcoming

1. need when connector device is located at casing to lock and connect device and casing admittedly, too trouble by spiral shell.

2. be difficult for forming the touching end of negative pole.

3. need to offer screw fixed hole in addition on retaining piece, it wastes manufacturing cost.

The utility model advantage

1. do not need when connector device is located at casing to fix by external substance.

2. it is that housing forms the loop that directly communicates, and only needs to be in contact with one another by shell fragment and contact flat spring and casing just can.

3. reduce cost, promote industrial competitiveness.

Embodiment

Now cooperate icon, figure number and embodiment to be described in detail as follows with regard to the utility model.

Execution mode of the present utility model provides a kind of connector construction and improves, as Fig. 6, Fig. 7 and shown in Figure 8, when its connector B was installed in casing H, making its housing D was the touching end of negative pole, was that elasticity and its casing H of shell fragment D2 by housing D and contact flat spring D3 itself is competing.

Its terminal pedestal E is equiped with metal terminal E1, but correspond to circuit board G and conducting by metal terminal E1, with its terminal pedestal E by pedestal C | side is sleeved in the C4 of fit portion of pedestal C, moreover, its housing D both sides are provided with symmetrical support D1, wherein support D1 wore the camphane ditch C1 of portion, and made the support D1 of its housing D be rendered as parallel pattern with the pin C2 of pedestal C, and combining pattern and just can increase steadiness on its housing D and the pedestal C by the down ditch C1 of portion and support D1.

When its connector B is welded in circuit board G, camphane ditch C1 of portion on its pedestal C and the mutual camphane of support D1 on the housing D are located in the circuit board G, like this, can increase the steadiness on its connector B and the circuit board G, be difficult for being directed at the support D1 damage of pin C2 or the housing D of pedestal C, and connector B seriously is shifted because of the fit portion frequent plug of C4 of C on interfacing part F and the pedestal.

When its interfacing part F is placed in the C4 of fit portion on the pedestal C, its interfacing part F is by a plurality of shell fragment C3 of top base C5 and bottom base C6, firm more its interfacing part F combines with the C4's of fit portion, moreover, the down ditch C1 of portion on its pedestal C can be provided with a plurality of more than so that make pedestal C and housing D between firm more with closely.

The above only is the preferable possible embodiments of the utility model, non-so limit claim of the present utility model, the equivalent structure that all utilization the utility model specifications and diagramatic content are done directly or indirectly applies to correlative technology field, all should be contained in the scope of the present utility model.
