The utility model in order to solve the problems of the technologies described above the technical scheme that adopts is:
A kind of SIM card card holder connector terminal, take the one side of this terminal and SIM card electrical contact as positive direction, comprise that one is the matrix of the tabular structure of bar, be provided with an elastic contact chip, the front of described elastic contact chip one end and this matrix is connected, the described elastic contact chip other end extends to form the termination contact district along the bending that faces up of this matrix, this termination contact district can with the SIM card Elastic Contact; Be provided with respectively the first leg and the second leg near place, elastic contact chip both sides on the described matrix, and described first and second leg is all near the joint of elastic contact chip and matrix, described first and second leg all is the concave hole type structure, and the concave surface of described concave hole type structure is towards positive direction.
Its further technical scheme is:
Described elastic contact chip is along the length direction setting of described matrix strips platy structure.
Corresponding elastic contact chip location offers an elongated through hole on the described matrix, and described elastic contact chip can elasticity be placed in this elongated through hole.
Described elastic contact chip is served as reasons to extend from the bending that faces up with the matrix of elongated through hole one end joint and is consisted of.
Described first and second leg concave hole type structure is communicated with described elongated through hole near a side of elongated through hole.
End away from first and second leg on the described matrix offers a circular accepting hole.
The described terminal structure that is formed in one.
Useful technique effect of the present utility model is: this terminal is provided with two legs, and described two legs all adopt the concave hole type structure, and the concave surface of this concave hole type structure is towards the front of terminal, and then convex surface is at the terminal reverse side; When terminal is arranged in the plastic cement fixed pedestal, between its reverse side and the plastic cement fixed pedestal certain interval is arranged, then convex portions just in time is contained in wherein, has reduced thickness and the length of SIM card deck; Simultaneously because a terminal is provided with two place's pads, so that single pin is with two place's pads, power is held in the weldering that has increased deck and Mobile phone PCB, and has strengthened contact performance.

Embodiment
Below in conjunction with Fig. 3 to Fig. 5 the utility model is described in further detail.
A kind of SIM card card holder connector terminal is take the one side of this terminal and SIM card electrical contact as positive direction.This terminal comprises that one is the matrix 1 of the tabular structure of bar, be provided with an elastic contact chip 2, this elastic contact chip 2 is along the length direction setting of 1 tabular structure of matrix, and the front of these elastic contact chip 2 one ends and matrix 1 is connected, and the mode of being connected can be welding or one-body molded mode.
Described elastic contact chip 2 other ends extend to form termination contact district 3 along the bending that faces up of this matrix 1, this termination contact district 3 can with the SIM card Elastic Contact; Be provided with respectively the first leg 4 and the second leg 5 near place, elastic contact chip 2 both sides on the described matrix 1, and described first and second leg 4,5 is all near the joint of elastic contact chip 2 with matrix 1, described first and second leg all is the concave hole type structure, and the concave surface of described concave hole type structure is towards positive direction.Terminal adopts sheet metal to make, then first and second leg of described concave hole type structure by the parts of respective shapes in the opposite direction jack-up form.
