CN2535935Y - Improved structure of electric connector - Google Patents

Abstract

The utility model relates to an improved structure for an electric connector, which is comprises a plastic base and a plurality of conductive terminals, wherein the base is a long-rectangular block with a reverse L-shaped, and a plurality of longitudinal grooves with paralleled intervals are arranged on the base. Pluralities of blocking grooves with inner flanges whose two sides are extended upwards in certain gap are arranged on the relative bottom of the grooves. The sections of the conductive terminals take box shape, and symmetrical barb portions are disposed on the lateral faces. A level welding portion is depressed and extended on the middle portion of the front edges of lateral bottom of the conductive terminal, and a pair of clipping portions which are opposite to the barb portions are perpendicularly folded upwards on the middle portion of the top lateral face of the conductive terminal. After assembly, the utility model really prevents the conductive terminals falling, and simplifies the programming of the electric connector.

Description

The structure-improved of electric connector

Technical field

The utility model relates to electric type, and particularly a kind of structure-improved of electric connector refers to that especially a kind of processing procedure is simple, and fastness and the good electric connector structure of contact.

Background technology

Be generally used in the electric connector of mobile phone or battery, because volume is small, not only assembling is difficult for, processing procedure is loaded down with trivial details, and cost is also high, and conducting terminal and plastic seat body are when joining, normal not good and be easy to come off because of the contact of terminal, and cause the shortcoming of loose contact.

The utility model content

The purpose of this utility model is exactly the shortcoming at the connector existence of above line mobile phone or battery, a kind of structure-improved of electric connector is provided, make the processing procedure of electric connector of mobile phone, battery more simple and easy, increasing work efficiency, and make the electric property of electric connector better; Its structure is to be provided with a plastic seat body, is provided with the longitudinal fluting of most parallel distances on plastic seat body, is provided with the draw-in groove that most bilaterals extend suitable spacing inward flange downwards on the relative bottom of groove, convexes with the reference column that can insert circuit board on the anterior end surface; Multi-conducting terminals generally is a  font, on bottom side, be provided with the hangnail portion of symmetry, and the welding of extending a level to lower recess by place in the middle of its bottom side leading edge is all, in addition its top side face leading edge in the middle of the place bend the clip portion of tool symmetry hangnail portion vertically downward; During combination, make conducting terminal by after when being inserted in the groove of plastic seat body, its clip portion can inwardly clamp the anterior end surface of groove, and be embedded on the inwall of groove by its hangnail portion, its weld part stretches out outside the draw-in groove forward in addition, also be embedded on the inwall of draw-in groove, make stationarity more good, and assembling is more easy by its hangnail portion.

Description of drawings

Fig. 1 is a perspective exploded view of the present utility model.

Fig. 2 is a three-dimensional combination schematic diagram of the present utility model.

1 is that plastic seat body, 11 is that groove, 12 is that draw-in groove, 13 is that reference column, 121,121 ' is that inward flange, 2 is that conducting terminal, 21,21 ', 23,23 ' is that hangnail portion, 22 is that weld part, 24 is a clip portion.

Embodiment

As shown in Figure 1, the utility model includes the multi-conducting terminals 2 that folder is established on plastic seat body 1 and the plastic seat body 1 and constitutes, wherein, plastic seat body 1 section is down the L shaped rectangle block of growing crosswise, which is provided with the longitudinal fluting 11 of most parallel distances, on the relative bottom of each groove 11, be provided with most bilaterals and extend downwards suitable spacing inward flange 121,121 ' draw-in groove 12, convex with the reference column 13 that can insert circuit board on the anterior end surface; Multi-conducting terminals 2, section is a  font, on bottom side, be provided with the hangnail portion 21,21 ' of symmetry, and extend the weld part 22 of a level by place in the middle of its bottom side leading edge to lower recess, in addition its end face leading edge in the middle of the place bend tool symmetry hangnail portion 23,23 ' clip portion 24 vertically downward.

As shown in Figure 2, when assembling, with conducting terminal 2 by after be inserted in the groove 11 of plastic seat body 1, its clip portion 24 can inwardly clamp the anterior end surface of groove 11, and closely be embedded on the inwall of groove 11 by its hangnail portion 23,23 ', its weld part 22 stretches out forward outside the draw-in groove 12 in addition, also closely is embedded on the inwall of draw-in groove 12 by its adjacent hangnail portion 21,21 ', outwards comes off to prevent conducting terminal 2.

In sum, the utility model reaches laterally and vertical dual chimeric purpose, and makes the assembling of electric connector more convenient, and keep preferable contact performance with clip portion and hangnail portion thereof that conducting terminal is provided with.

Claims (1)

1, a kind of structure-improved of electric connector, it is to be made of plastic seat body (1) and multi-conducting terminals (2), it is characterized in that: the section of plastic cement seat (1) is down the L shaped rectangle block of growing crosswise, which is provided with the longitudinal fluting (11) of most parallel distances, on the relative bottom of each groove (11), be provided with the draw-in groove (12) that most bilaterals extend suitable spacing inward flange downwards, convex with the reference column (13) that can insert circuit board on the anterior end surface; The section of multi-conducting terminals (2) is a  font, on bottom side, be provided with hangnail portion (21), (21 ') of symmetry, and by locating to extend the weld part (22) of a level to lower recess in the middle of its bottom side leading edge, the middle place of its top side face leading edge bends the clip portion (24) of tool symmetry hangnail portion (23), (23 ') vertically downward in addition.
