Description

A kind of pusher structure

Technical field:

The utility model relates to technical field of electric connectors, refers in particular to a kind of electric connector that is used for, the pusher structure of process auxiliary drive electric connector shell fragment.

Background technology:

The push rod that is used for electric connector generally is to be used for the auxiliary shell fragment of pushing on the electric connector inserted terminal, to reach the person that extracts the connector.The user promotes push rod, and the press head of push rod front end is then depressed the press-side of shell fragment, can make the screens point on the shell fragment withdraw from screens, promptly removes the clamping of electric connector inserted terminal and respective external socket, realizes freely extracting electric connector thus.And traditional pusher structure; self does not have elastic construction; when assembling is used; in order to reach automatically reseting of push rod, also need to be equipped with the compression spring usually, and compression spring and push rod assembling; there is location inconvenience; structural stability is poor, dismounting inconvenience, and the high defective of cost of manufacture, thereby requires further improvement.

The utility model content:

The purpose of this utility model is to overcome the defective of prior art, provides a kind of simple in structure, push rod and elastic component integral structure, and easy processing and fabricating and easy-to-assemble pusher structure.

For achieving the above object, the utility model adopts following technical scheme:

A kind of pusher structure, this push rod have on the other hand a moved end and a working end, on push rod also one-body molded flexible; Elastic component is the axial compression elastic construction.

Described elastic component is snakelike shape, is molded in the dead slot in push rod stage casing, extends axially by push rod, and front end is a movable end, and is provided with a top on movable end, and the rear end of elastic component and push rod fuse.

On the side of described push rod, also be provided with the guide rail bar.

The manual end of described push rod has one can limit the step position that pushes the degree of depth.

Adopt said structure, one-body molded flexible of the push rod that the utility model provides, both self relative fixed need not to locate separately assembling, like this, when actual assembled is used, optimized location structure, assemble more conveniently, quick, and package assembly is stable, improves the service behaviour of push rod.

The utility model advantage again is that elastic component and push rod are integrated, and promptly push rod self has spring function, improves the functional and usability of push rod, can satisfy many-sided the use; And elastic component is done snakelike shape design, is housed in the dead slot in push rod stage casing, and good springiness is not subject to external interference during work, long service life, and rational in infrastructure, cost of investment is low, and the operation operation is easy, has improved the operation ratio and the operability of push rod greatly.

Description of drawings:

Accompanying drawing 1 is the perspective view of push rod described in the utility model;

Accompanying drawing 2 is the end view of Fig. 1;

Accompanying drawing 3 is used for one embodiment schematic diagram on the electric connector for the utility model;

Accompanying drawing 4 is that the structure of Fig. 3 is used schematic diagram;

Accompanying drawing 5 is the compression schematic diagram of elastic component under the state of Fig. 4.

Embodiment:

Below in conjunction with accompanying drawing the utility model is further specified:

Consult shown in Fig. 1,2, a kind of pusher structure described in the utility model, this push rod 1 is a bluff body, has a moved end 11 and a working end 12 on the other hand, manually end 11 promotes to manipulate for users, and manually holds and have one on 11 and can limit the step position 111 that pushes the degree of depth; And working end 12 realizes pushing when mobile can making the screens point on the shell fragment withdraw from screens by the press-side of the shell fragment on the electric connector, removes the clamping of electric connector inserted terminal and respective external socket, realizes freely extracting electric connector thus.On push rod 1 also one-body molded flexible 13, elastic component 13 is the axial compression elastic construction.Shown in Figure 1, elastic component 13 is snakelike shape, be molded in the dead slot 14 in push rod 1 stage casing, extend axially by push rod 1, front end is a movable end, and is provided with a top 131 on movable end, and the rear end of elastic component 13 and push rod 1 fuse, movable end can be to the back extreme direction compress energy storage of elastic component 13 during use, and movable end can provide the resiliency urged push rod when stretching.

Shown in Fig. 1,2, install for convenience and the increase guidance quality, on the side of push rod 1, be provided with guide rail bar 15, guide rail bar 15 and push rod 1 integral production, during assembling, guide rail bar 15 inserts in the guide groove of respective carrier, and guiding and location are provided, and it is more steady that push rod 1 is moved.

Shown in Fig. 3,4,5, the push rod that provides for the utility model is used for the schematic diagram on the electric connector 2, the shell of this electric connector is combined to form by loam cake 21 and lower cover 22, the mounting groove 211 of opening hollow tube-shape before and after loam cake 21 is provided with, mounting groove 211 front openings are guided loam cake 21 inner undersides into, and mounting groove 211 open rearward end are drawn loam cake 21 rear ends; Be provided with in the rear end of lower cover 22 raise up block piece 221, block piece 221 coupling mounting groove 211 open rearward end setting-ins just.During assembling, push rod 1 inserts in the mounting groove 211 of loam cake from back to front, (not shown) in the guide groove of also corresponding insertion mounting groove 211 sides of the guide rail bar 15 on push rod 1 side, cover loam cake 21 and lower cover 22 then, the piece 221 of blocking of lower cover 22 holds to be packed with and cover 21 rear end, and props up the rear end of withstanding push rod 1, and the front end of push rod 1 is propped up the step 212 that peaks at loam cake 21 inboards by elastic component 11 elasticity, elastic component 11 provides the elasticity of compression, satisfies the job requirement of the telescopic moving of push rod 1 front end.

Shown in Fig. 4,5, promote the manual end 11 of push rod 1, push rod 1 moves in mounting groove 211, working end 12 moves and acts on the press-side 31 of the shell fragment 3 of electric connector forward, make the screens point 32 on the shell fragment 3 withdraw from screens, promptly remove the clamping of electric connector inserted terminal and respective external socket, realize freely extracting electric connector thus.Push rod 1 is in mounting groove 211 when mobile forward, snakelike elastic component 13 is under 212 tops effects of step of a top 131 and loam cake inboard, axial compression, compress smooth, non-warping distortion, provide reduction with good elasticity to push rod 1, push rod can well be resetted when decontroling outside motive force, reach the elastic reset requirement.The manual end 11 of push rod 1 has one can limit the step position 111 that pushes the degree of depth, and the top is propped up with the end of mounting groove 211 in step position 111, limits the degree of depth that pushes of push rod 1 thus.

The utility model is on push rod 1 one-body molded flexible 13, and both self relative fixed need not to locate separately assembling, like this, when actual assembled is used, optimized location structure, assemble more conveniently, quick, and package assembly is stable, improves the service behaviour of push rod.Elastic component 13 is done snakelike shape design, and is simple in structure, has enough elasticity; Elastic component 13 is housed in the dead slot 14 in push rod stage casing, and good looking appearance is generous, is not subject to external interference during work, long service life, and rational in infrastructure, cost of investment is low, and the operation operation is easy, has improved the operation ratio and the operability of push rod 1 greatly.
