Abstract

The utility model relates to an electric connector which using a pressing way to assemble and connect an electric element. The utility model comprises an insulation body and a plurality of conductive terminals arranged in the insulation body, wherein, partial conductive terminals are protruded and exposed outside the insulation body, and each conductive terminal is provided with a first contact part and a second contact so as to electrically contact with the electric element butted with the electric connector. The electric elements are butted with the electric connector in a pressing way, and thus, in the process of assembly, oppressing force is needed to force the electric element to be oppressed at the contact part of each conductive terminal so as to cause the conductive terminals to generate elastic deformation; in the process, the electric element respectively, orderly, and electrically contacts with the first contact part and the second contact part.

Description

Electric connector

[technical field]

The relevant a kind of connector of the utility model with face contact mode winding electric component.

[background technology]

With the develop rapidly of operation of electric element speed, its packing forms is in continuous variation, and the also constantly development of structure of carrying the electric connector of these electric components.For reduce the encapsulation volume between electric component and electric connector and reduce electric component and electric connector between the electric signal transmission path, generally on electric component, establish the electrical contact zone of sheet, press on the face way of contact on the electric connector of counter structure,, the electric signal transmission path reduces its resistance so that reducing, can effectively prevent the signal disorder that high-speed transmission environment causes, its correlation technique document please refer to " Nonlinear Analysis Helps Design LGA Connectors " (Connector Specifier, February, 2001).

In the winding process, impel the conducting terminal in the electric component compressing electric connector and make it that strain take place to guarantee stable electric connection between electric component and electric connector thereby impose an active force, relevant patent please refer to United States Patent (USP) the 6th, 293, No. 805, the 6th, 296, No. 495, the 6th, 293, No. 806, the 6th, 146, No. 152 and the 6th, 027, No. 345 grade discloses.Yet, when electric component is pushed the conducting terminal of electric connector, the contact site of conducting terminal produces displacement along force direction, in this simultaneously, contact site also can be along an approximate circle arcuation track start, with respect to electric component, this contact site is promptly along producing displacement perpendicular to force direction, if electric component is bigger along the displacement that force direction moves, the contact site of conducting terminal is also bigger perpendicular to the displacement of force direction with respect to the electric component edge, and make the contact site slippage of conducting terminal go out the corresponding electrically contact zone of electric component easily, thereby the electrically phenomenon of not conducting appears.

[utility model content]

The purpose of this utility model is to provide the electric connector of the preferable electrical contact effect of a kind of tool.

The purpose of this utility model is achieved in that the utility model electric connector comprises insulating body and is arranged at wherein a plurality of conducting terminals, and it is outer and be provided with the electric component that first contact site and second contact site dock with the utility model electric connector in order to electrical contact that wherein conducting terminal partly is exposed to insulating body.Electric component butts up against electric connector of the present utility model in the mode of pushing, thereby, in the winding process, need to make every effort to promote and this electric component is oppressed make conducting terminal produce strain and be contained in insulating body in the contact site of conducting terminal with a compressing, in this process, electric component then is taken up in order of priority and is electrically contacted with first contact site and second contact site.

Compared with prior art, the utlity model has following advantage: because two contact sites of conducting terminal tool electrically contact with the butt joint electric component, not smooth defective can effectively prevent to electrically conduct.

[embodiment]

See also Fig. 1 to Fig. 4, in present embodiment, the utility model electric connector 1 is planar lattice array (LGA) electric connector, it comprises insulating body 10 and conducting terminal 20, wherein insulating body 10 is provided with first surface 101 and second surface 102, be distributed with plurality of terminals accepting groove 103 between two surfaces symmetrically and evenly, before terminal containing slot 103, convex with stage portion 1031, be extended with in insulating body 10 by stage portion 1031 and protrude out plate 1032, protrude out and then be provided with first accepting groove, 1033, the first accepting grooves 1033 between plate 1032 and the stage portion 1031 and be concaved with and interfere groove 1034.In addition, terminal containing slot 103 slightly middle both sides are provided with a buckle angle 1035, and buckle angle 1035 lower limbs then are provided with second accepting groove 1036.Accepting groove 103 is provided with fixture block 1037 with the stage portion 1031 corresponding other ends, and the bottom side then protrudes out

supporter

1038, and 1038 of fixture block 1037 and supporters are the 3rd accepting groove 1039.

Conducting terminal 20 is a Curved Continuous tabs, it is provided with a support portion 201, support portion 201 1 ends are provided with kink 202,201 one-tenth one normal throws are provided with weld part 203 from its other end and support portion, the tail end 205 that weld part 203 extends upward interference part 204 and is connected and is provided with interference part 204 through bending.Kink 202 extends elastic portion 206 obliquely, elastic portion 206 protrudes out phase first contact site 207 and second contact site 208 across a certain distance, 208 of this first contact site 207 and second contact sites form certain drop, bend out a holding section 209 downwards by first contact site, 206 free terminals, holding section 209 is provided with two wing plates 2091.

See also Fig. 4 and Fig. 5, when going into 20 groups of these conducting terminals in the insulating body, with the kink 202 of conducting terminal 20 and support portion 201 along A to being inserted into the 3rd set accepting groove 1039 of insulating body 10, in this simultaneously, holding section 209 is along in 1035 winding to the second accepting grooves 1036 of engaging angle, and relies on himself elasticity to make holding section 209 be close to engaging angle 1035.Then, the tail end 205 of conducting terminal 20 presses down along the B direction, the latter half of conducting terminal 20 is moved down along kink 202, and make support portion 201 to terminating in supporter 1038, tail end 205 butt stage portion 1031, and weld part 203 extends outside the insulating body from second accepting groove, 1036 bottom sides, by above assembly process, interference groove 1034 Joints of the interference part 204 of conducting terminal 20 and first accepting groove 1033, further fixing conducting terminal 20.
