Description

Conducting terminal

[technical field]

The utility model relates to a kind of conducting terminal, relates in particular to the conducting terminal that is used for connecting a chip module.

[background technology]

The conducting terminal relevant with the utility model can be with reference to TaiWan, China patent M350121, and it discloses a kind of conducting terminal, comprises the first terminal, second terminal and places spring between the former two.Second terminal is arranged with a pair of contact arm, and forms a passage between this a pair of contact arm, with the contact site of the correspondence of holding the first terminal.During operating state, the contact site of the first terminal inserts between a pair of contact arm and is held.

Usually, the excessive the first terminal that causes of chucking power that is subjected to for the contact site of avoiding the first terminal plugs inconvenience, aforementioned chucking power generally can not design very big, yet, when conducting terminal is in abnormal condition, the a pair of contact arm of second terminal may just can't provide enough chucking powers, and then causes the electrical contact between the first terminal, second terminal unstable.

Therefore, be necessary to provide a kind of improved conducting terminal, to overcome the defective of conventional conductive terminal.

[utility model content]

Technical problem to be solved in the utility model provides a kind of conducting terminal, can guarantee electrical stability in contact between the first terminal, second terminal.

For solving the problems of the technologies described above, the utility model provides a kind of conducting terminal, comprises the first terminal and second terminal, and wherein the first terminal is provided with a contact site, but the second terminal correspondence is provided with a pair of contact arm of the aforementioned contact site of clamping, and wherein a pair of contact arm is not isometric design.

Compare with correlation technique, conducting terminal of the present utility model has the following advantages: a pair of contact arm of second terminal is not isometric design, can provide different moment loadings in contact site, the first terminal is deflected, can increase the chucking power that contact arm acts on contact site, and then improve electrical stability in contact between the first terminal, second terminal.

[embodiment]

Please refer to Fig. 1, conducting terminal 1 of the present utility model comprises a first terminal 10 that is positioned at the top, be positioned at second terminal 12 of below and place between first, second terminal and part coats the spring 14 of first, second terminal, and wherein the first terminal 10, second terminal 12 roughly are platy structure on the whole respectively.

The first terminal 10 is provided with a main part 100, and the top of autonomous body 100 has extended upward one and connected a little 102 to contact with external module (as chip module), and independently a contact site 104 is extended towards second terminal, 12 directions in the bottom of body 100.The relative both sides of main part 100 are provided with first abutting part 1000, and the end of contact site 104 laterally is provided with a stop section 1040 respectively in both sides.

Second terminal 12 is provided with a base portion 120 and from the base portion 120 a pair of contact arm 122,124 that extends upward of the relative both sides of an end wherein, wherein contact arm 122,124 extends upward L1, L2 length from base portion 120 respectively, and L1 is greater than L2.Be formed with between two contact arms passage that can hold contact site 104 and two contact arms on convex with a projection 1220,1240 towards the other side respectively; Two projectioies 1220,1240 are used for clamping the first terminal 10, and they are different to base portion 120 distances.In addition, base portion 120 grows a projection respectively to the periphery with the junction of contact arm 122,124, and this two projection forms second abutting part 1200.Simultaneously, base portion 120 tapers off to a point 1202 in its afterbody away from an end of contact arm 122,124, to contact with external electronic components.

Please refer to Fig. 2, during assembling, the first terminal 10 and second terminal 12 roughly are the perpendicular quadrature shape, the contact site 104 of the first terminal 10 is inserted between the contact arm 122,124 and can moves up and down, and the stop section 1040 of the first terminal 10 ends cooperates with projection 1220,1240 can prevent that the first terminal 10 and second terminal 12 break away from easily.Aforementioned spring 14 limits its position around the peripheral of the first terminal 10, second terminal 12 and by first abutting part 1000, second abutting part 1200.

Please refer to Fig. 3, because contact arm 122,124 is from base portion 120 extended length differences, when the contact site 104 of the first terminal 10 is touched arm 122,124 clampings, contact arm 122,124 provides a chucking power F1, F2 by projection 1220,1240 respectively, since contact arm 122,124 respectively from the upwardly extending length L of base portion 120 1 greater than L2, so contact arm 122 acts on the moment of contact site 104 acts on contact site 104 greater than contact arm 124 moment.Therefore, during use, because the suffered moment unbalance in contact site 104 both sides, cause the first terminal 10 that the trend of deflection is arranged, and then make F2 that the trend that becomes big be arranged, help keeping electrical stability in contact between the first terminal 10, second terminal 12, particularly under abnormal operating state.
