Description

The conducting terminal of socket connector

Technical field

The utility model is about a kind of socket connector terminal, particularly about a kind of conducting terminal of zero-force connector for socket.

Background technology

As shown in Figure 1, the Taiwan patent discloses a kind of conducting terminal 1 of Zero insertion connector for No. 82214129.This conducting terminal 1 has a flat holding section 10, and these holding section 10 1 ends have a v-angle breach 100.One elastic portion 11 is circular arc from this breach bottom and extends these holding section 10 ends that turn back, and at its terminal circular arc contact site 12 that forms.The spacing of this contact site 12 and holding section 10 greater than with CPU stitch (not shown) distance of inserting, can insert and avoid being scratched for CPU stitch zero insertion force.The CPU stitch that inserts is advanced circular arc contact site 12 places under the connector lock-out state, the elasticity that provides by elastic portion 11 and keep Elastic Contact with contact site 12.

The elastic portion 11 of above-mentioned conducting terminal 1 is that 10 breach 100 extends from the holding section, and its elasticity arm of force is short and be difficult to the elasticity that provides enough, and then causes: contact site 12 contacts not tight with the CPU stitch on the one hand; On the other hand under the CPU stitch repeatedly promotes elastic portion 11 might be from the holding section 10 breach 100 places tear and damage terminal 1.

In view of the foregoing, the conducting terminal of this existing socket connector is needed improvement badly.

The utility model content

The purpose of this utility model just is to provide a kind of conducting terminal of socket connector, and this conducting terminal can provide enough elasticity to guarantee to contact with the tight of grafting stitch.

For achieving the above object, the utility model provides following technical proposals: a kind of conducting terminal of socket connector, the weld part that comprises a base portion, extends from base portion one end, and an elastic arm.This elastic arm comprises a forearm from base portion extension weld part one end bending extension, and this forearm is tilted to the postbrachium that base portion extends certainly, reaches the contact site that extends from this postbrachium end.

Weld part at first extends downwards from base portion one end, and a pad is extended in then vertical bending.The contact site of elastic arm is to open arc of base portion or V-arrangement, is a guiding space between this contact site and the base portion.The base portion upper center is provided with a breach, with the contact pin collision of better avoiding and inserting.In one embodiment, this base portion also comprises a junction, and elastic arm and weld part extend from this connecting portion.

Compare with existing electronic card connector assembly, the elastic arm of the conducting terminal of socket connector of the present utility model extends to the relative other end from the base portion one end bending of conducting terminal, but not the indentation, there from the same end of base portion is extended in the prior art.Thereby the elasticity brachium, can provide enough elastic forces to contact with the contact pin of insertion is stable.

Embodiment

For better understanding spirit of the present utility model, it is described further below in conjunction with a preferred embodiment of the present utility model.

Shown in Fig. 2-4, one is to be used for a CPU socket connector 3 according to socket connector conducting terminal 2 of the present utility model, this socket connector 3 comprises plurality of terminals accepting groove 30, and each conducting terminal 2 promptly is contained in the corresponding terminal containing slot 30 and sets up electrical connection with CPU contact pin 4 tight contacts of inserting.

As Fig. 4-7, weld part 21 and elastic arm 22 that the conducting terminal 2 of this socket connector 3 has a base portion 20, extend to extend from base portion 20 1 ends.

This base portion 20 is the vertical flat board of U-shaped roughly, and the upright portion of its U-shaped 200 both sides have protruded out some hangnails 201.The U-shaped bottom of base portion 20 is the arcuation bending and extends a junction 202, and weld part 21 extends from these connecting portion 202 1 end both sides respectively with elastic arm 22.

Weld part 21 bends under connecting portion 202 1 side direction earlier and extends one section, vertically bends a horizontally extending circular pad 210 again.

Elastic arm 22 comprises a forearm 220, the postbrachium 221 that extends of this forearm 200 certainly, and from this postbrachium 221 extend towards base portion 20 open arcuation contact sites 222 (also can be other shapes such as V-arrangement).This forearm 200 extends the relative opposite side horizontal-extending of weld parts 21 and goes out from connecting portion 202.This postbrachium 221 is from forearm 220 other ends bendings and be tilted to base portion 20 free ends and extend, and this postbrachium 221 in the extension process to the vertical center line A place of this U-shaped base portion 20 crankle, thereby make the axis of symmetry B of this contact site 222 aim at this center line A.So form an open as far as possible guiding space 23 between this contact site 222 and base portion 20, the breach of U-shaped base portion 20 can guarantee that the zero insertion force of CPU contact pin 4 inserts, and can not bump with conducting terminal 2 in addition.

As shown in Figure 3, the conducting terminal 2 of this socket connector 3 is contained in the corresponding terminal containing slot 30, and the upright portion 200 of the U-shaped of base portion 20 is stuck in the draw-in groove 300 of terminal containing slot 30.Simultaneously by the interference of hangnail 201 with terminal containing slot 30 inwalls of upright portion 200, and in conducting terminal 2 is immobilizated in.

CPU contact pin 4 inserts guiding space 23 from terminal containing slot 30 tops, then under the push rod on the loam cake 31 of socket connector 3 32 promotes with contact site 222 Elastic Contact of elastic arm 22.And then be soldered to weld part 21 on the circuit board (not shown) by conducting terminal 2, realize with circuit board between be electrically connected.The contact site 222 of this arc or V-arrangement provides wide as far as possible guiding space 23 near base end on the one hand again, on the other hand the contact pin 4 that advances is formed half clip pack and has guaranteed that contact site 222 contacts with the multiple spot of contact pin 4.

Certainly the shape of this conducting terminal each several part is not limited to that the utility model discloses, and can make pins type etc. according to the requirement of welding procedure as weld part, does not influence essence of the present utility model.

Elastic arm of the present utility model is to extend to the opposite end of this base portion through twice bending from an end of base portion, has the elastic force brachium than prior art, the advantage of elasticity foot.Extend from base portion one end simultaneously and extend, be difficult for tearing, thereby terminal structure is more stable from the base portion indentation, there.

Technology contents of the present utility model and technical characterstic disclose as above, yet those of ordinary skill in the art still may be based on teaching of the present utility model and announcements and done all replacement and modifications that does not deviate from the utility model spirit.Therefore, protection range of the present utility model should be not limited to the content that embodiment discloses, and should comprise various do not deviate from replacement of the present utility model and modifications, and is contained by the present patent application claim.
