Abstract

The utility model relates to a modified structure of electric connector, in particular to an electric connector capable of allowing a male terminal to contact and engage with a female terminal upon a smooth surface. The utility model comprises an insulating base body and a plurality of terminals. A storage space is arranged within the insulating base body and allows the plurality of terminals to enter therein from an engagement portion. The engagement portion is provided in the storage space to allow the engagement of two oppositely-arranged smooth surfaces adjacent to two oppositely-arranged rough surfaces. Two oppositely-arranged smooth surfaces of the plurality of terminals extend outward from the storage space to form a welding portion, allowing the two oppositely-arranged smooth surfaces of the plurality of terminals in plug-in connection with the female terminal. Such arrangement can avoid the arc effect and enable good electrical connection between the male and female terminals.

Description

The improvement structure of electric connector

Technical field

The utility model provides a kind of improvement structure of electric connector, and You Zhike contact the electric connector of combination for male terminal with shiny surface with female terminal, and the shiny surface that utilizes terminal to avoid the producing electric arc effect, provides excellent electrical property connection between terminal for the combination of pegging graft.

Background technology

In the general electronic product, as devices such as computer, TV, sound equipment, LCD screen, its inside will be provided with circuit board or motherboard, when circuit board or motherboard during in work, certainly will supply with certain operating voltage by external power source, just otherwise can't operate.So, circuit board or motherboard need see through lead and electric connector connects, with use as transferring electric power, and under the existing production automation and modular trend, be directly with lead and the direct solid welding of circuit board in early days, so can't satisfy the condition of modularization and automation, thus, just have an electric connector is set up in the end of lead, and on circuit board, motherboard or other device, corresponding electric connector is set, by the combination of two electric connectors, to reach fast insert-pull and reusable function.

Because the electric connector on motherboard or the circuit board uses high voltage design, the male female end contact of its pairing, because of being subjected in the restriction of space and structural design, must use the pattern of female, male plug, and the plural male terminal A1 among its male plug A sees also shown in Figure 6, shearing the back through punching press in two sides formation matsurface A11, and with matsurface A11 for combining with the plural female terminal B1 butt joint of female B, yet, the male terminal A1 of the electric connector that prior art is used is when using, have following each defective, as:

When (one) the matsurface A11 of male terminal A1 docks with female terminal B1, easily produce friction and cause and to form electric connection and cause between male terminal and female terminal by arc discharge.

(2) the matsurface A11 of male terminal A1 produces arc discharge, will cause the splatter of contact surface melting, vaporization or material, and make male terminal A lose the usefulness of transmission signal.

Therefore, how to solve above-mentioned problem of commonly using and defective, be the relevant manufacturer that is engaged in the industry and desire most ardently the direction place that research improves.

Summary of the invention

Main purpose of the present utility model is to provide a kind of electric connector to improve structure, this electric connector comprises that insulating base frame and plural terminals form, and the accommodation space in the insulating base frame penetrates with the docking section for plural terminals, the docking section supplies butt joint with two opposite side shiny surfaces in accommodation space, two opposite side shiny surfaces with plural terminals are provided with weld part toward the accommodation space extension, can combine with the female terminal grafting by plural terminals two opposite side shiny surfaces, and can avoid producing the electric arc effect, provide male terminal to be connected with the female terminal excellent electrical property.

Below with reference to accompanying drawing and preferred embodiment of the present utility model its feature and function are described in detail.

Embodiment

Please consult shown in Fig. 1,2,3 simultaneously, be stereo appearance figure of the present utility model, the three-dimensional exploded view before assembling, the sectional axonometric drawing after assembling, find out that by knowing among the figure electric connector of the present utility model is made up of insulating base frame 1 and plural terminals 2; Wherein:

This insulating base frame 1 is provided with accommodation space 11 in inside, accommodation space 11 1 sides are that docking section 111, opposite side then are connecting portion 112.

This plural terminals 2 is sheared with punching press and is formed, the top and bottom two opposite side faces of its docking section 21 are for shearing formed matsurface 211, and two opposite side faces are level and smooth shiny surface 212 in addition, and by docking section 21 directly outward behind the lateral buckling, give bending forward again, be formed with weld part 22 through two roads bending program.

Above-mentioned each member is when assembling, accommodation space 11 with insulating base frame 1 penetrates and forms the location for plural terminals 2 with docking section 21, and docking section 21 is positioned in the accommodation space 11,212 of its shiny surfaces are positioned at the position (please consulting Fig. 4, shown in Figure 5 simultaneously) that can dock with female terminal 31, and plural terminals 2 is 21 opposite side in the docking section, then extend weld part 22 toward connecting portion 112 directions of accommodation space 11, promptly group constitutes electric connector of the present utility model.

See also Fig. 4, shown in Figure 5 again, be the stereo appearance figure of the utility model preferred embodiments, the stereo appearance figure of another embodiment, by can clearly finding out among the figure, electric connector of the present utility model is with insulating base frame 1, penetrate back location for plural terminals 2 with docking section 21 with accommodation space 11, and the weld part 22 of plural terminals 2 opposite sides, behind the connecting portion 112 that extends insulating base frame 1, weld part 22 may be molded to the plane weld part of tool 22, so that can adopt surface stuck (SMT) weldering to be located on the circuit board; Maybe weld part 22 can be shaped to straight-bar type, then can utilize weld part 22 to pass (Through hole) after the perforation on the circuit board, weldering is located on the circuit board again; So that can reach the purpose that the insulating base frame 1 of electric connector is fixedly arranged on circuit board.And after insulating base frame 1 is installed in circuit board, can utilize insulating base frame 1 to peg graft for female 3, and with the female terminal 31 of female 3 inside shell fragment 311,312 with both sides, shiny surface 213 for insulating base frame 1 internal terminal 2 penetrates connection, and peg graft when combining with level and smooth shiny surface 212 and shell fragment 311,312, unlikely generation arc discharge can avoid terminal 2 and the docking of female terminal 31 can't transmission signal.

Above-mentioned detailed description is at a kind of preferable possible embodiments explanation of the utility model, this embodiment is not in order to limit claim of the present utility model, all other do not break away from the equalization of being finished under the skill spirit that the utility model discloses to be changed and modifies change, all should be contained in the claim that the utility model contains.

In sum, the architecture advances of electric connector of the present utility model has obvious effect when using, really meet the patent requirement of novelty, utility model and progressive, files an application in accordance with the law.
