Description

Electric connector

The relevant a kind of electric connector of the utility model especially refers to a kind of electric connector that is used for the connecting circuit plate to circuit board.

Relevant prior art of the present utility model can be consulted United States Patent (USP) the 5th, 842, and No. 875, cases such as No. the 81107106th, TaiWan, China patent application and No. 83208692.Existing electric connector includes insulating body and conducting terminal, and its conducting terminal is by going into insulating body inside by bottom surface, insulating body below group, and the weld part of conducting terminal is soldered on the circuit board by the surface adhesion technology again.Yet the assembling of these electric connectors by conducting terminal by the below of insulating body organize into, in assembling process, easily damage is caused at the scolding tin position of conducting terminal, and can not guarantee the excellent planar degree and the normotopia degree of conducting terminal welding position, cause " rosin joint " phenomenon in the welding process easily, and its operating process inconvenience, the raising of unfavorable production efficiency.

The purpose of this utility model is to provide a kind of electric connector; can effectively protect the scolding tin effect of conducting terminal, reach excellent electrical property transmission, and it is easy to assembly fast and good operating characteristics can be provided; thereby shorten the processing procedure of electric connector, reduce product cost.

The purpose of this utility model is reached like this: it includes structures such as insulating body and conducting terminal, wherein the insulating body bilateral symmetry is provided with the plurality of terminals accepting groove, be provided with supporter and stage portion in the terminal containing slot, conducting terminal is a Curved Continuous tabs, it is provided with a support portion, and support portion one end is provided with kink, and the other end then is provided with welding foot, welding foot extends upward the interference part through bending, and the interference part is connected with tail end.Again, kink extends elastic portion obliquely, and the contact arm that the protruding emersion of elastic portion can connect with circuit board, contact arm end in addition bend out a holding section downwards, and the holding section is provided with two wing plates.Organize fashionable, can be earlier the kink and the support portion of conducting terminal be inserted into the 3rd set accepting groove of insulating body from the body top of insulating, meanwhile, the holding section is along in engaging angle winding to the second accepting groove, and relies on himself elasticity to make the holding section touch the engaging angle.Then, the tail end of conducting terminal is pressed down, the lower portion of conducting terminal is moved down along kink, and make the support portion prop up supporter, tail end butt stage portion, and till welding foot extends from the second accepting groove bottom side.

By above structure, can realize that conducting terminal goes into from the insulating body upper set, can effectively protect the scolding tin effect of conducting terminal, and easy to assembly fast, be beneficial to and enhance productivity.

Below by accompanying drawing and preferred embodiment the utility model is further described.

Fig. 2 is the conducting terminal stereogram of the utility model electric connector.

Fig. 3 is the insulating body cutaway view of the utility model electric connector.

Fig. 4 is the schematic diagram of the conducting terminal group of the utility model electric connector when going into insulating body.

Fig. 5 is the schematic diagram after the conducting terminal group of the utility model electric connector is gone into insulating body.

See also Fig. 1 to shown in Figure 3, the utility model electric connector includes structures such as insulating body 1 and conducting terminal 2, wherein insulating body 1 is a rectangular body, be provided with first surface 10 and second surface 100, be distributed with plurality of terminals accepting groove 12 between two surfaces symmetrically and evenly, before terminal containing slot 12, be concaved with stage portion 18, extend in insulating body 1 by stage portion 18 and to protrude out plate 11, protrude out and then be provided with first accepting groove, 17, the first accepting grooves 17 between plate 11 and the stage portion 18 and be concaved with and interfere groove 172.Again, both sides are provided with a buckle angle 15 in the middle of terminal containing slot 12 summaries, and buckle angle 15 lower edges then are provided with in 17 summaries of second accepting groove, 152, the second accepting grooves, 152 to the first accepting grooves and contract.Accepting groove 12 is provided with fixture block 13 with the stage portion 18 corresponding other ends, and the bottom side then stretches out

supporter

14, and 14 of fixture block 13 and supporters are the 3rd accepting groove 132.

Conducting terminal 2 is a Curved Continuous tabs, and it is provided with a support portion 21, and support portion 21 1 ends are provided with kink 22, and the other end then is provided with welding foot 23, and welding foot 23 extends upward interference part 27 through bending, and interference part 27 is connected with tail end 28.Again, kink 22 extends elastic portion 24 obliquely, the contact arm 25 that elastic portion 24 protruding emersions and circuit board connect, and contact arm 25 end in addition bends out a holding section 26 downwards, and holding section 26 is provided with two wing plates 29.

Organize fashionable, see also shown in Figure 4, with the kink 22 of conducting terminal 2 and support portion 21 along A to being inserted into the 3rd set accepting groove 132 of insulating body 1, meanwhile, holding section 26 is along in 15 winding to the second accepting grooves 152 of engaging angle, and relies on himself elasticity to make holding section 28 touch engaging angle 15.Then, the tail end 28 of conducting terminal 2 presses down along the B direction, the lower portion of conducting terminal 2 is moved down along kink 22, see also shown in Figure 5ly, and make support portion 21 prop up supporter 14, tail end 28 butt stage portion 18, and till welding foot 23 extends from second accepting groove, 152 bottom sides, by above process, the interference part 27 of conducting terminal 2 contacts with the interference groove 172 of first accepting groove 17, further fixing conducting terminal 2.

Because of conducting terminal 2 is gone into from the upper set of insulating body 1; with respect to conducting terminal 2 organize from the below of insulating body 1 into; more can effectively protect the scolding tin effect of welding foot 23; reach the excellent electrical property transmission; and engaging angle 15 can be by the size of change self size; can control the height that contact arm 25 stretches out insulating body 1 surface, the stressed size when contacting with circuit board with reasonable adjustment electric connector.
