Electric connector

[skill field art]

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that chip module is electrically connected to circuit board

[technical background]

The novel patent of TaiWan, China has disclosed a kind of electric connector M342637 number, and it is used to connect chip module to circuit board.This electric connector comprises pedestal, be contained in plurality of conductive terminals in the pedestal, be assembled in the pedestal drive unit that can move up and down with respect to pedestal, be assembled in baffle and the fixed head between pedestal and baffle in the pedestal.Conducting terminal is pressed into the bottom of conducting terminal from pedestal the pedestal by a tool usually, but the plane that the conducting terminal of the electric connector that prior art discloses is pushed for tool is less, make tool push instability, thereby cause terminal to insert poor effect.

Therefore, necessary existing electric connector is improved to overcome the aforementioned disadvantages of prior art.

[utility model content]

The purpose of this utility model is to provide a kind of electric connector that tool is pushed conducting terminal of being convenient to.

The purpose of this utility model is achieved through the following technical solutions: a kind of electric connector, be used for accommodating chip module, it comprises pedestal, be immobilizated in plurality of conductive terminals in the pedestal, be set up on the pedestal and drive unit that can move up and down with respect to pedestal and the loading plate that is contained in the pedestal and can moves horizontally in pedestal, described conducting terminal has a pair of upwardly extending clamping limb, wherein extend protuberance at least one clamping limb, the bottom of protuberance forms one and pushes end face.

Compared to prior art, the utility model electric connector can effectively increase and push area by protuberance is set on conducting terminal, thereby has improved the stability when tool is pushed conducting terminal.

[embodiment]

See also Figure 1 and Figure 2; a kind of electric connector 1 that is used for test chip module (not shown), it comprises pedestal 20, be contained in plurality of conductive terminals 3, the loading plate in pedestal 20 21, locked instrument 22, posting 23 in the pedestal 20, be assembled in the pedestal 20 drive unit 4, the baffle 5 that is assembled in pedestal 20 bottoms and the fixed head 6 between pedestal 20 and baffle 5 that can move up and down with respect to pedestal 20.

Pedestal 20 upper set are provided with loading plate 21, locked instrument 22 and posting 23, and the below group is provided with fixed head 6 and baffle 5.Loading plate 21 is assembled in the pedestal 20 by pin 211, and its both sides are provided with the projection 212 that drives for drive unit 4.Locked instrument 22 is assembled on two relative sidewalls of pedestal 20.Drive unit 4 is provided with some pins 43, and drive unit 4 can be up and down on the sidewall that is held in pedestal 20 on ground by pin 43.Drive unit 4 is provided with the actuating arm 42 that matches with the projection 212 of loading plate 21.The place, four angles of drive unit 4 is provided with four

pillars

41, and 20 4 corners of pedestal are provided with four perforates 203 corresponding to four pillar 41 places of drive unit 4, respectively are provided with a spring 7 in the perforate 203, and pillar 41 is contained in the perforate 203 and is arranged in the spring 7.Loading plate 21, pedestal 20, fixed head 6 and baffle 5 correspondences are provided with some terminal accommodation holes 210,200,60 and 50 of accommodating conducting terminal 3.

As shown in Figure 3, the utility model conducting terminal 3 comprises upwardly extending a pair of clamping limb 31 and 32, is connected the connecting portion 35 of clamping limb 31,32 and the welding ends 33 that is extended to form by connecting portion 35 downwards.Wherein, clamping limb 31 is a rest arm, and integral body is type linearly, and clamping limb 32 is a moveable arm, has bending structure and has certain elasticity.The top of two clamping limbs 31,32 forms respectively and is used for the bare terminal end 310,320 of the tin ball on the clamping chip module.Two clamping limbs 31,32 respectively extend a protuberance 341,342 in the edge and the equal-height position of homonymy, the bottom of protuberance 341,342 forms to be positioned at pushes end face 3410,3420 on the same plane, and it is vertical to push pack into the direction of electric connector 1 of end face 3410,3420 and conducting terminal 3.Connecting portion 35 links to each other two clamping limbs 31,32 on lateral margin opposite with protuberance 341,342 on the clamping limb 31,32.When being assembled into conducting terminal 3 in the electric connector 1, adopt tool (not shown) by pushing end face 3410,3420 conducting terminal 3 is pressed into pedestal 20 from bottom to top and being immobilizated in the terminal accommodation holes 200 of pedestal 20, bare terminal end 310,320 upwards passes the terminal accommodation holes 210 of loading plate 21, and welding ends 33 passes the terminal accommodation holes 60 of fixed head 6 downwards.Baffle 5 can be protected welding ends 33, prevents that it from bending.The utility model is by being provided with protuberance 341,342, effectively increased conducting terminal 3 is pressed into the area of pushing in pedestal 20 processes, and reduced and pushed unsettled risk.

When operating this electric connector 1, drive unit 4 is applied downward external force, locked instrument 22 pressurizeds outwards upset are opened pedestal 20, simultaneously actuating arm 42 moves horizontally to pedestal 20 1 ends with making loading plate 21 cooperating of projection 212, the movable clamping limb 32 of conducting terminal 3 follow that loading plate 21 moves together and with static clamping limb 31 away from.Can put into chip module posting 23 this moment, and the tin ball (not shown) of chip module bottom is between the bare terminal end 310,320 of a pair of clamping limb 31,32.Remove external force then, spring 7 is with drive unit 4 and posting 23 pop into position, and loading plate 21 also resets by being positioned at its terminal spring 8 owing to removing of external force.The corresponding tin ball of two clamping limbs, 31,32 closed clampings of conducting terminal 3.Be known technology about the concrete type of drive of conducting terminal 3 and the concrete structure of loading plate 21, be not repeated at this.

Protuberance in above the utility model better embodiment is a rectangular configuration, the section of pushing of bottom is the plane vertical with the conducting terminal direction of insertion, in addition, protuberance also can be arranged to other shape, as integral body structure triangular in shape, the bottom push the structure that end face still remains the plane.Push end face and also the oblique angle that is certain can be set, also can realize improving the effect of pushing stability in the conducting terminal assembling process this moment.
