Abstract

An electric connector used to realize the electric connection between butting plug and circuit board comprises an insulating body and a conductive terminal, wherein a butting hole for holding the butting plug and a terminal receiving groove are arranged on the insulating body; the conductive terminal is arranged in the terminal receiving groove, comprising a fixed grasped part, a bent part extending conversely along the inserting direction of the butting plug from the tail end of the fixed grasped part, and a contact part obliquely stretching into the inside of the butting hole from the bent part, and the bent part is arranged on the side of the insulating body close to the back end of the butting hole. With the arrangement, when the volume of the insulating body is reduced, the bent part of the conductive terminal can still keep the original bent degree, which contributes to the maintenance of better elasticity.

Description

Electric connector

The utility model relates to a kind of electric connector, refers to a kind of electric connector in order to achieve a butt joint and to electrically connect between plug and circuit board especially.

The prior art relevant with the utility model can be with reference to laid-open U.S. Patents 4 on January 15th, 1985,493, shown in No. 526, the electric connector that the prior art disclosed has flexible terminal, this flexible terminal comprises holding parts, is located at the weld part and the kink at holding parts two ends respectively, and the contact site that the butt joint direction along banjo is extended from kink, wherein kink is near the butt hole front end of electric connector.So be provided with, when the electric connector volume is big, can keep reliably being connected with banjo.But, microminiaturization day by day along with electronic installation, the volume and the size that adopt the aforementioned structure design certainly will dwindle electric connector, because the existence of aforementioned butt hole, the space that holds kink is limited, therefore the size of flexible terminal also must be done corresponding dwindling, the easy like this terminal kink elasticity that causes is not enough and increase the possibility of plastic deformation, so, and reliable butt joint the between unfavorable assurance flexible terminal and banjo, simultaneously, shorten the useful life of connector.

The electric connector that the utility model purpose is to provide a kind of terminal to have preferable elasticity, dock with banjo reliably, plasticity_resistant deformation is good and useful life is long.

For achieving the above object, the utility model is by the following technical solutions: this electric connector comprises that insulating body and group are located at the conducting terminal in the insulating body, wherein insulating body comprises butt hole and the terminal containing slot in order to accommodate banjo again, the conducting terminal group is located in the terminal containing slot, comprise holding parts, the kink from the holding parts end along the reverse extension of banjo grafting direction and from the oblique contact site that stretches into butt hole inside of kink, and kink is housed in the side near the insulating body of butt hole rear end.By such deploying, after the insulating body volume reduced, the conducting terminal kink still can keep its original bending degree and be beneficial to the elasticity that keeps preferable.

Compared to prior art, the kink of the utility model terminal and butt hole front end are oppositely arranged, therefore after the volume of insulating body reduces, terminal still can keep original bending degree, thereby be beneficial to conducting terminal and guarantee elasticity preferably, so provide a kind of terminal to have preferable elasticity, dock with banjo reliably, plasticity_resistant deformation is good and useful life is long electric connector.

The utility model is described in further detail below in conjunction with accompanying drawing and preferred embodiment.

Fig. 1 is the three-dimensional combination figure that the utility model is applied to the connector module.

Fig. 2 is a partial enlarged drawing of the present utility model among Fig. 1.

Fig. 3 is the stereogram of the utility model conducting terminal.

Please refer to Fig. 1, Fig. 2 and shown in Figure 3, the utility model electric connector 3 comprises that insulating body 30, group are located at the first terminal 31 and conducting terminal 32 in the insulating body 30.Wherein insulating body 30 comprises main part 300, and autonomous body 300 1 sides and main part 300 vertical docking section 301 and the protuberances 302 that also extend in parallel backward, long and narrow space between docking section 301 and the protuberance 302 then is formed for accommodating the butt hole 308 of banjo (not shown), the end that banjo inserts earlier is defined as the front end of butt hole 308, and then the other end is called the rear end.Docking section 301 is provided with the through hole 303 of accommodating the first terminal 31, and protuberance 302 is provided with the terminal containing slot 304 of accommodating conducting terminal 32.Main part 300 is provided with the opening 306 that is connected with terminal containing slot 304, and extension is provided with draw-in groove 307 under opening 306 1 side direction.

The first terminal 31 is housed in the through hole 303 of insulating body 30, and conducting terminal 32 then is housed in the terminal containing slot 304 of insulating body 30.Wherein conducting terminal 32 comprises that tabular holding parts 321, the end from holding parts 321 close butt hole 308 rear ends are weld part 322 and the kink 323 that forked extends, and from the contact site 324 of kink 323 other ends to the oblique bending extension of butt hole 308 front ends, wherein said weld part 322 is the drop setting with holding parts 321, and 323 of kinks extreme directions before the butt hole 308 extend and are reverse setting with weld part 322.Weld part 322 ends are provided with a welding foot 325, and contact site 324 ends are provided with a butt sheet 326.

When 32 groups of conducting terminals were gone into insulating body 30, described holding parts 321 inserted and is retained on an end of terminal containing slot 304 contiguous main parts 300 from draw-in groove 307, thereby conducting terminal 32 is retained in the terminal containing slot 304.323 of kinks are housed in the opening 306 of main part 300, and contact site 324 from kink 323 ends along reverse oblique the stretching in the butt hole 308 of banjo grafting direction, butt sheet 326 at contact site 324 ends is connected on terminal containing slot 304 inwalls of contiguous butt hole 308 front ends, is used for locating contact site 324.Weld part 322 is extended outside the draw-in groove 307 by holding parts 321 ends, and welding foot 325 is parallel to the lower wall of insulating body 30, is used for being welded on the printed circuit board (PCB) (not shown).

In the present embodiment, because kink 323 is extended by the end of holding parts 321 near butt hole 308 rear ends, and be contained in main part 300 near in the opening 306 of butt hole 308 rear ends, after so insulating body 30 reduces, only change the distance of 303 of opening 306 and through holes, and opening 306 can keep life size constant, thereby conducting terminal 32 kinks 323 can keep original bending degree, and can reduce the possibility of conducting terminal 32 plastic deformations and guarantee conducting terminal 32 normal stress and positive forces.

Please refer to shown in Figure 1ly, be applied to an embodiment of connector module for the utility model.This connector module 1 comprises the shielding casing 5 on signal connector 2, electric connector 3 and inclusion signal connector 2 and the electric connector 3, and wherein signal connector 2 comprises that insulating base frame 20 and group are located at the signal terminal 21 in the insulating base frame 20.
