Abstract

The utility model provides an electric connector, which is used for connecting and abutting electronic components to a circuit board. The electric connector comprises an insulating body and a conductive terminal accommodated in the insulating body; the conductive terminal is provided with a fixed part; the fixed part is provided with a bending part which bends and extends aside; the insulating body is provided with a passage matched with the bending part; a rail propping up the lower end of the bending part is arranged inside the passage. The elasticity of the conductive terminals thereby can be increased to absorb the energy resulting from impact outside and to buffer the impact outside on the conductive terminal and the parts adjacent to the conductive terminal (such as the insulating body, a tin ball, butted electronic components, the circuit board and so on); the rail propping up the bending part can play a role in stopping and supporting, and can prevent siphon when the electric connector is welded, thereby ensuring the normal performance of the electric connector and excellent electric connection between the butted electronic components and the circuit board.

Therefore, be necessary to design a kind of novel electric connector, to solve foregoing problems.

[summary of the invention]

The purpose of this utility model is to provide a kind of electric connector, it can absorb and add the excessive power that invests on the conducting terminal, and the available buffer external impact is to the impact of conducting terminal and the parts that are adjacent (as insulating body, tin ball, butt joint electronic building brick and circuit board etc.).

For achieving the above object, the utility model electric connector, be used for connecting the butt joint electronic building brick to circuit board, it comprises insulating body and is contained in conducting terminal in the insulating body, wherein said conducting terminal is provided with fixed part, described fixed part side direction bending extension is provided with kink, and described insulating body is provided with the channel that can match with kink, is provided with the horizontal bar of replacing the kink lower end in the described channel.

Compared with prior art, the utility model novel electric connector, its described kink can increase the elasticity of conducting terminal, to absorb the energy that external impact produces, the buffering external impact to conducting terminal and the parts that are adjacent (as insulating body, the tin ball, butt joint electronic building brick and circuit board etc.) impact, and described horizontal bar both can play the effect of replacing kink, also can play effect spacing or that support, and produce siphon in the time of can preventing the electric connector welding, thereby guarantee the normal serviceability of electric connector, guarantee to dock that excellent electrical property is connected between electronic building brick and circuit board.

[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model electric connector is described further.

With reference to Fig. 1, the utility model electric connector 1 is used for connecting butt joint electronic building brick (not shown) to circuit board (not shown).

As shown in Figure 1, the utility model electric connector 1 comprises insulating body 2 and is contained in conducting terminal 3 in the insulating body 2.

As shown in Figure 2, conducting terminal 3 is provided with fixed part 31, described fixed part 31 side direction bending extension is provided with kink 34, described kink 34 is c-shaped and have elasticity, take this this kink 34 and can increase the elasticity of conducting terminal 3, to absorb the energy that external impact produces, the buffering external impact is to the impact of conducting terminal 3.Described kink 34 extends downward vertically and is provided with weld part 33, and described weld part 33 is in same plane with fixed part 31, and described weld part 33 bottoms one side is provided with holding section 331, and described weld part 33 bottoms can overlap tin ball 4.Described fixed part 31 tops one side is provided with holding part 311.Upwards bend the oblique again bending extension of extension by fixed part 31 and be provided with main part 32, described main part 32 comprise by fixed part 31 be provided with the relative outward extending shoulder 321 of opposite side of a side of holding part 311, shoulder 321 earlier downwards more upwards the bridge part 322 that extends of bending, bridge part 322 by extending upward the connecting portion 323 that forms and constituting along the connecting portion 323 upward elastic arms 324 that extend to bending, wherein shoulder 321, bridge part 322 and connecting portion 323 surround one " U " font structure jointly, and elastic arm 324 ends are contact site 320.
