Description

Electric connector

The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector to realize electrically connecting between described circuit board between two printed circuit board (PCB)s that is folded in.

Now, along with electronic product develops towards the direction that increased functionality, part are simplified day by day, most common form is that the circuit of finishing each function is concentrated on respectively on the different printed circuit board (PCB)s.In same electronic product, just have a plurality of printed circuit board (PCB)s like this, and the electric connection between two circuit boards is finished by the electric connector that is folded in therebetween normally.The design form of relevant this type electric connector is various, wherein as laid-open U.S. Patents the 5th on October 25th, 1994,358, this kind electric connector that is disclosed for No. 411, it comprises insulating body and several conducting terminals, and insulating body interlocks at the middle part of two side and is provided with the coupling hole that several laterally run through, and conducting terminal is provided with the affixed arm of respective amount at the described coupling hole of correspondence place, matched by coupling hole and affixed arm, conducting terminal can be fixed on the insulating body reliably.

Combination Design between aforementioned terminal and insulating body is for the electric connector with larger volume, a kind of easy, effective design of can yet be regarded as.But worked as this kind electric connector volume enough hour, this kind design not only can make the coupling hole of described insulating body be difficult to make in molded process, and also will the intensity of insulating body obviously be reduced after making.

On November 2nd, 1999 laid-open U.S. Patents the 5th, 975, then disclosed the design of another kind of such connector for No. 914, this design mainly is must mold a plurality of elastic bending parts before terminal is installed in insulating body, become complicated shortcoming with the processing procedure that causes this electric connector, be provided with a plurality of coupling holes and directly run through along the direction of vertical printed circuit plate in the both sides of matching surface, insert in it by the conducting terminal that will be vertical bar shaped earlier, then further it is bent into required terminal shape again to form finished connector product.Though this kind design makes the connector processing procedure become simply to a certain extent, it does not overcome the defective of 5,358, No. 411 described designs of above-mentioned United States Patent (USP) equally.

The purpose of this utility model is to overcome the defective of prior art, and a kind of electric connector is provided, and it not only makes insulating body and conducting terminal easy to manufacture, and the affixed intensity of insulating body is improved and and conducting terminal between simple and convenient assembly.

To achieve these goals, the utility model comprises that mainly an insulating body and several are surface mounted in the conducting terminal on the described insulating body, wherein insulating body is provided with the affixed post in location that plurality of outward is extended on the surface, two opposite sides of vertical printed circuit plate, and conducting terminal is at the location coupling hole that is provided with respective amount with respect to the affixed post in described location place.Matched by described location coupling hole with the affixed post in location, can conducting terminal is easy, be retained on the insulating body reliably.

Because the utility model is matched with the surface by being directly arranged in location coupling hole corresponding on the affixed post in lip-deep location, insulating body two opposite sides and the conducting terminal, therefore, the utility model can overcome insulating body terminal coupling hole manufacturing difficulty in the prior art effectively, and the reduction of insulator structure intensity reaches the shortcoming of assembling inconvenience with conducting terminal.

Describe preferred forms of the present utility model in detail below in conjunction with accompanying drawing.

Fig. 1 is a three-dimensional exploded view of the present utility model.

Fig. 2 is the three-dimensional combination figure after the utility model prepackage.

Fig. 3 is the finished product stereogram after the utility model assembling is finished.

Please refer to shown in Fig. 1,2 and 3, the utility model comprises insulating body 1 and conducting terminal 2.

Insulating body 1 body structure that is rectangle, include two

matching surface

11,12 respect to one another and

side surfaces

13,14, wherein matching

surface

11,12 is adjacent with two printed circuit board (PCB)s (not icon) respectively and connect with it, and 13,14 of side surfaces are used for installing conducting terminal 2 and vertical with described printed circuit board (PCB).For being located reliably, conducting terminal 2 is fixed on the ad-hoc location of insulating body 1, inwardly further be concaved with several location respect to one another accepting

grooves

15,16 between two lengthwise ends of matching

surface

11,12, accepting

groove

15,16 places in then corresponding described location convex with the affixed post 17 in several location that are arranged in a straight line on side surface 13,14.Matched by described affixed post 17 with the location coupling hole 25 on the conducting terminal 2, and by described

location accepting groove

15,16 with 22 spacing the accommodating wherein of the elastic portion on the conducting terminal 2, conducting terminal 2 firmly is fixed on the insulating body 1.

Conducting terminal 2 is surface mounted on the insulating body 1, it is to be formed by the punch forming of metal lamellar body, include Fixed Division 21, elastic portion 22 and contact site 23, wherein Fixed Division 21 slightly is " U " shape, convex with affixed 24 in the one middle side edge along the longitudinally that is parallel to

side surface

13,14, be provided with at this middle part of affixed 24 and locate the location coupling hole 25 that affixed post 17 matches.By described location coupling hole 25 and affixed post 17 Joints, can conducting terminal is 2 easy, be retained on the insulating body 1 reliably.22 of elastic portion are located at two " U " shape end of Fixed Division 21, and it extends along the direction that tilts with respect to matching

surface

11,12, with when the utility model and printed circuit board (PCB) connect, provide certain Elastic Contact power.Contact site 23 is to extend from the other end of elastic portion 22 to form, and further protrudes outside the

matching surface

11,12 of insulating body 1, its respectively with two printed circuit board (PCB)s on corresponding line connect mutually, between two printed circuit board (PCB)s, to constitute an electrical loop.

When assembling, earlier the conducting terminal 2 for preparing is gone into for 13,14 groups from the surface, two opposite sides of insulating body 1 respectively, so that the elastic portion 22 on these conducting terminals 2 of going into from the both sides group respectively is interlaced with each other, and be housed in respectively in the

location accepting groove

15,16 corresponding on the insulating body 1, simultaneously, the affixed post 17 in location that is convexly equipped with on set location coupling hole 25 and the

side surface

13,14 on the Fixed Division 21 on it socket-connects (Fig. 2 shows).Then, to put to fuse machine through the electric connector of prepackage and carry out hot melt, the end that makes on its insulating body 1 the affixed post 17 in location is in affixed compacting on conducting terminal 2 under the state of semi-molten, so make described conducting

terminal

2 and 1 of insulating body reach reliably, stably affixed.
