Abstract
The utility model discloses an electric connector which comprises a conductive terminal and an insulating body for accommodating the conductive terminal. The conductive terminal comprises a retaining part, an elastic part formed by bending and extending one end of the retaining part, a contact part for connecting the elastic part, a pre-pressing part extending from the end of the contact part, a welding part extending from the other end of the retaining part, a connecting part formed by bending and extending the welding part, and a stopping piece extending horizontally from the end of the connecting part to the contact part. After the electric connector is assembled, the pre-pressing part of the terminal is rested against the bottom of the stopping piece. Therefore, the pre-pressure of the terminal can act on the insulating body, thereby preventing the deformation of the insulating body and the occurrence of missing soldering.
Description
[technical field]
The utility model is relevant a kind of electric connector, refers to a kind of electric connector with precompressed terminal structure especially.
[background technology]
U.S. Pat 6,231 discloses a kind of electric connector 394 B numbers, and it comprises insulating body and is contained in plurality of terminals in the insulating body.This terminal comprises weld part, connecting portion, holding parts, elastic portion, contact site and crossbeam.This connecting portion connects weld part and holding parts, and elastic portion is extended from the bending of the holding parts other end, and connects contact site, and crossbeam extends to oblique front lower place protrusion from the end of contact site.Be provided with the projection that holds crossbeam in insulating body.
Chinese patent CN 2587078 Y numbers another electric connector is disclosed, it comprises insulating body and is contained in the interior plurality of terminals of insulating body that its terminal has an arc-shaped contact part, the U-shaped elastic portion from the extension of arc-shaped contact part one end, the holding parts that the own elasticity portion other end extends and the weld part that bends extension from holding parts downwards.One crossbeam protrudes extension from the end of arc-shaped contact part to oblique front lower place, and reflexed is inside.Be provided with the projection that the crossbeam with terminal offsets in insulating body.
More than two pieces of patents crossbeam of all disclosing out terminal can be fastened on the projection of insulating body, because terminal has elastic portion, this elastic portion can apply precompression upwards by crossbeam on the projection of insulating body, when this precompression is big, can cause the buckling deformation of insulating body, cause terminal the phenomenon of empty weldering in the process of SMT, to occur.
Thus, necessary associated components and structure to existing electric connector improved, to overcome aforementioned disadvantages of the prior art.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector that has the precompressed terminal structure and prevent the insulating body buckling deformation.
For achieving the above object, the utility model adopts following technical scheme: a kind of electric connector, it comprises conducting terminal and is used to accommodate the insulating body of this conducting terminal, wherein conducting terminal comprise holding parts, the elastic portion of extending from the bending of an end of holding parts, the contact site that connects elastic portion, from the terminal pre-splenium that extends of contact site and from the horizontally extending weld part of the other end of holding parts, the connecting portion that extends from weld part bending and from the connecting portion end to the horizontally extending sheet of keeping out of contact site, after the assembling, the pre-splenium of conducting terminal is connected to the below of keeping out sheet.
Compared with prior art, the utlity model has following beneficial effect: after the assembling, the pre-splenium of conducting terminal is connected to the below to washer.The precompression of conducting terminal just can not act on the insulating body like this, can prevent that then the insulating body distortion from can not produce the phenomenon of empty weldering yet.
[description of drawings]
Fig. 1 is conducting terminal be about to pack into a three-dimensional exploded view in the insulating body in the utility model electric connector.
Fig. 2 is the three-dimensional combination figure of electric connector shown in Figure 1.
Fig. 3 is the stereogram of conducting terminal in the utility model electric connector.
[embodiment]
See also Fig. 1 to shown in Figure 3, the utility model electric connector 100 can be installed on the circuit board (not shown), and this electric connector 100 includes insulating body 4, is contained in the plurality of conductive terminals 5 in the insulating body 4.
Insulating body 4 is roughly rectangular, is made by insulating material, the surface that is installed on circuit board be fitting surface 41, with these fitting surface 41 facing surfaces be contact-making surface 42, a pair of first end face 43 and second end face 44 of be linked and packed face 41 and contact-making surface 42.Symmetrical center line with fitting surface 41 and contact-making surface 42 is as the criterion, and is penetrated with the relative terminal containing slot 45 of two rows from contact-making surface 42 to fitting surface 41, and the both sides in each terminal containing slot 45 are respectively arranged with the holding slot 46 of fixing conducting terminal 5.
Conducting terminal 5 forms for sheet metal punching press bending, it comprises holding parts 51, the elastic portion 52 of extending from the end bending of holding parts 51, the contact site 53 that connects elastic portion 52, from the contact site 53 terminal pre-spleniums that extend 54 and the connecting portion 56 that extends from the horizontally extending weld part 55 of the other end of holding parts 51, from weld part 55 bendings and from connecting portion 56 ends to the horizontally extending sheet 57 of keeping out of contact site.
During assembling, at first, push the contact site 53 of conducting terminal 5 downwards with the power that tilts, it is close to holding parts 51 to make contact site 53 drive pre-splenium 54, when with pre-splenium 54 butts when keeping out the lower surface of sheet 57, stop to push; Secondly, the conducting terminal 5 after will pressing down with tool inserts respectively in the insulating body 4 by holding slot 46.
After the assembling, the pre-splenium 54 of conducting terminal 5 is connected to the below to washer 57.Precompression is transferred to conducting terminal 5 self bear, precompression just can not act on the insulating body 4 like this, can prevent that insulating body 4 distortion from can not produce the phenomenon of empty weldering yet.
Should be pointed out that the above a kind of preferred implementation of the present utility model that only is, other any equivalent transformation that carries out on this execution mode basis does not break away from essence technical scheme of the present utility model.
