Abstract

The utility model relates to the technical field of an electric connector, in particular to an elastic piece structure of a connector. The elastic piece is assembled on a connector body and has an inverted hook, an elastic arm, a pressing part and a fixed part; wherein the inverted hook is arranged at the front end of the elastic arm and can assist the plugging of the connector; the pressing part is linked with the elastic arm and can drive the inverted hook; the rear end of the elastic arm is connected with the fixed part which is made of piece material of the elastic piece, rolls over and is bent corresponding to the elastic arm; the fixed part is U-shaped and is provided with an upper folded edge and a lower folded edge which are parallel or form an acute angle; the upper folded edge is connected with the lower side of the rear end of the elastic arm; and the lower folded edge extends toward the front end of the elastic arm, and is provided with barbs so as to be clamped on the connector body when in assembling. The fixed part is made of piece material of the elastic piece, rolls over and is bent corresponding to the elastic arm; the formed U-shaped body is flat, increases working surfaces and has good elasticity and pressure resistance, thus improving the elasticity of the elastic piece and guaranteeing that the inverted hook on the elastic arm protrudes from the clamping position normally; and the elastic piece structure of the connector has convenient assembly and long service life.

Description

The electric connector elastic piece structure

Technical field:

The utility model relates to technical field of electric connectors, refers in particular to a kind of connector elastic piece structure.

Background technology:

Known, be used for the connector of signal of telecommunication transmission, because easy to use, have that promptly to pull out be plugging function, thereby be widely used in electronic product.

Glue core grafting screens for subconnector generally is provided with on connector and can pushes shrapnel, but this shell fragment has the overhead kick of subconnector grafting and anti-back, and overhead kick is arranged on the elastic arm, and elastic arm connects the fixed part of shell fragment.Shown in Figure 1, in the prior art, the fixing part structure of shell fragment is that parallel with elastic arm design is not very desirable at grade, and after repeatedly pushing, shell fragment very easily deforms, deliquescing, and elasticity weakens, and makes overhead kick lose due effect, and useful life is short.

Summary of the invention:

The purpose of this utility model is to provide a kind of mounting structure stable, ease of assembly, and the lasting connector elastic piece structure of elasticity.

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

The electric connector elastic piece structure, this shell fragment is assembled on the connector body, shell fragment has overhead kick, elastic arm, press section and fixed part, overhead kick is arranged at the elastic arm front end, but subconnector is pegged graft, link elastic arm and can drive overhead kick in the press section, the elastic arm rear end is connected and fixed portion, and fixed part system is by the relative elastic arm rollover of the sheet material bending structure of shell fragment.Fixed part is a U-shaped, being parallel to each other is arranged or be the last lower hem of acute angle relation, and upper hem is connected the rear end downside of elastic arm, and lower hem extreme direction before the elastic arm extends, and lower hem is provided with hangnail, so that be equipped on the connector body during assembling.

In the such scheme, the relative elastic arm rollover of upper hem.

Connector body is provided with the U-shaped assembling grove with fixed part coupling, and keeps supplying the floating space that the groove position of flanging assembling provides shell fragment to push in the assembling grove, promptly pushes at shell fragment between upper hem and the groove position and leaves the space on the direction.

Shell fragment fixed part of the present utility model is by the relative elastic arm rollover of the sheet material bending structure of shell fragment, optimize fixing part structure, fixed part is offset to the left side or the right side of elastic arm relatively, the U-shaped body that forms is flat, add large working area, good springiness, and withstand voltage, promote the elasticity of shell fragment thus, just guarantee that also screens is normally protruded in the overhead kick on the elastic arm; Easy to assembly, long service life.

Accompanying drawing 2 is the elastic piece structure schematic diagram of the utility model;

Accompanying drawing 3 is the shell fragment and the main body assembling schematic diagram of the utility model;

Accompanying drawing 4 is the assembling back structural representation of Fig. 3;

Accompanying drawing 5A, 5B are the assembling partial structurtes schematic diagram of Fig. 4.

Embodiment:

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

Consult shown in Fig. 2,3,4,5A, the 5B, electric connector elastic piece structure described in the utility model, this shell fragment are assembled on the connector body 10, and shell fragment 20 has overhead kick 21, elastic arm 22, press section 23 and fixed part 24, is integral structure; Overhead kick is arranged at the elastic arm front end, but the subconnector grafting, and link elastic arm and can drive overhead kick in the press section, the elastic arm rear end is connected and fixed portion, fixed part 24 is that in the present embodiment, fixed part 24 is offset to the left side or the right side of elastic arm relatively by the relative elastic arm 22 rollover bending structures of sheet material of shell fragment.

Shown in Figure 2, fixed part is a U-shaped, being parallel to each other is arranged or be the last lower hem 241,242 of acute angle relation, upper hem 241 is connected the rear end downside of elastic arm 22, lower hem 242 extreme direction before the elastic arm extends, and lower hem 242 is provided with hangnail 2421, so that be equipped on the connector body 10 during assembling.The linking bias is played in the relative elastic arms rollover of upper hem 241, and change shell fragment sheet material towards, make the U-shaped body of formation flat, add large working area, good springiness, withstand voltage.

Shown in Fig. 3,4,5A, the 5B, connector body 10 is provided with the U-shaped assembling grove 11 with the fixed part coupling, and the floating space that the groove position 111 of keeping supplying flanging 241 assembling in the assembling grove 11 provides shell fragment to push is promptly pushed at shell fragment between upper hem 241 and the groove position 111 and is left the space on the direction.During assembling, shell fragment 20 inserts forward from body rear, fixed part 24 corresponding assembling grove 11 setting-ins, the lower hem 242 of fixed part 24 is fixedlyed connected with respective grooves, hangnail 2421 blockings and prevent that fixed part 24 from withdrawing from, and lower hem 242 is the support edge, erect overhead kick 21, elastic arm 22, press section 23 by it, upper hem 241 is done corresponding bending and is changed for being connected the limit, so that elastic arm obtains enough elasticity.Upper hem 241 activities are assembled in groove position 111, and the floating space that groove position 111 provides shell fragment to push.Thus, during enforcement, depress press section 23, then link elastic arm 22 and can drive overhead kick 21, remove the clamping of overhead kick 21 thus, can extract connector (during overhead kick 21 work be equipped in connector on the pedestal of inserting, this technology is a prior art, gives unnecessary details no longer one by one at this).

The relative elastic arm of shell fragment fixed part of the present utility model rollover biasing is made, and makes the U-shaped fixed part of formation flat, strengthens the carrying working face of fixed part, and good springiness, and withstand voltage promotes the elasticity of shell fragment thus.
