Description

The bayonet connector of band fixture

The utility model relates to a kind of bayonet connector, its for a kind of circuit board panel when being electrically connected with daughter board daughter board firmly plant, can be because of the bayonet connector of the band fixture of vibrating instant cut-off.

The structure of existing bayonet connector is shown in Figure 1A and Figure 1B, and this connector 1 is shown in Figure 1A, and its top is provided with the groove 101 that the way plate 11 of can powering is planted, and groove 101 is two side walls longitudinally, is provided with many for the ccontaining chase 102 of terminal 12.In addition, see also this connector 1 left and right sides of Figure 1B and be provided with and clamp folder 13, this clampings presss from both sides 13, and identical by moulding 131,132 and one bottom 133 constitutes but elasticity that be oppositely arranged is cranked arm, and this two elasticity is cranked arm and 131,132 is divided into

epimere

1311,1321;

Stage casing

1312,1322 and hypomere 1313,1323.The guide face of

epimere

1311,1321 for tilting,

stage casing

1312,1322 is a neck shape portion; Hypomere 1313,1323 is the stent cover with the epimere reversed dip, after circuit daughter board 11 is inserted in groove 101, except these terminals 12 itself have effect of inserting and putting (because of the not shown daughter board that is inserted and put by terminal of angular relationship), by this

neck

1312,1322 can be further with the left and right sides clamping of this circuit board 11.But because these terminals 12 and clamp the

neck shape portion

1312,1322 of folder 13 and circuit board 11 to insert and put the position very short apart from the distance from bottom of connector 1, circuit daughter board 11 areas own are very big, promptly the entire area that inserted and put of this circuit daughter board 11 is very little, therefore, when 11 vibrations of circuit daughter board, be easy to because loose contact and instant cut-off, influence is electrically connected normally.

Above-mentioned shortcoming all proposes improved method respectively in No. the 242446th, Taiwan patent announcement, United States Patent (USP) the 5th, 012, No. 264, the 5th, 211, No. 571, the 3rd, 573, No. 706 and the 4th, 898, No. 540.But still there is shortcoming in the actual use of these patents.

The purpose of this utility model is to provide a kind of bayonet connector with fixture, and it can firmly be planted the circuit daughter board, and plug use to be very easy to, and the fixture by the connector both sides is inserted and put the both sides of this circuit daughter board effectively.

The purpose of this utility model is to realize like this, a kind of bayonet connector with fixture promptly is provided, has a rectangular insulation shell, its long axis direction is provided with the groove that power supply way plate is planted, the both sides of groove are provided with many chases, a plurality of terminals, be arranged in the described chase, the one end is stuck in outside the insulation shell, the other end extends in and is the curved arc guide face in the chase, the spacing of the sub-curved arc guide face of opposite end retaining clip circuits daughter board, at least one side of this rectangular insulation shell is provided with fixture, and described fixture comprises the folder post that rectangular insulation shell both sides exceed and is located at the interior elastic spring of folder post.

The advantage of the utility model bayonet connector is, three clampings that its folder post and elastic spring constitute, outside decapacitation effectively inserts and puts circuit daughter board both sides, increase the scope that the circuit daughter board is inserted and put, lengthening inserts and puts the distance of place bottom rectangular insulation shell, can effectively resist vibration, avoid the instant cut-off influence to be electrically connected.

Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:

Figure 1A is the stereogram of existing bayonet connector;

Figure 1B is the B-B cutaway view of existing bayonet connector;

Fig. 2 is the bayonet connector three-dimensional exploded view of the utility model band fixture;

Fig. 3 is an insulation shell cutaway view among Fig. 2, and fixture and insulation shell connection status are shown;

Fig. 4 A is that the circuit daughter board is inserted in the cutaway view on the insulation shell groove of connector;

Fig. 4 B is that the circuit daughter board is inserted in the cutaway view on the insulation shell groove of connector.

See also Fig. 2 and Fig. 3, the bayonet connector of the utility model band fixture comprises, one rectangular insulation shell 2 and be located at terminal 3 in the housing, and the fixture 4 of being located at the housing both sides, as shown in the figure, this rectangular insulation shell 2, it is provided with groove 20 along long axis direction, and power supply way plate (seeing Fig. 4 A) is planted, in addition, groove 20 inner vertically both sides are provided with many chases 21, are used for ccontaining terminal 3.Shown in Fig. 4 B, an end 30 of each butt is stuck in outside the insulation shell in these terminals 3, for docking with circuit motherboard; The other end 31 bendings are arcuation, and the curved arc of both sides, assembling back terminal 3 forms is convenient to the guide face that the circuit daughter board inserts.In addition, the left and right sides of this rectangular insulation shell 2 is provided with fixture 4, this fixture 4 is made of folder post 40 and elastic spring 41 substantially, wherein this folder post 40 is directly extended by the both sides of rectangular insulation shell 2, form by first jig arm 401 and second jig arm 402, this two jig arm relatively is provided with, and keeps a suitable spacing that the circuit daughter board can be inserted and put; And the spacing of the top that this two jig arm 401,402 is oppositely arranged is less, is mainly used in and inserts and puts the circuit daughter board, and it is suitable more to enlarge guide face about and that groove both sides terminal 3 forms.This elastic spring 41 is to be made of Jiong type embedding part 410 and elastic portion 411, and wherein the faces that linked to each other by the breach 4101 of Jiong type embedding part 410 of elastic portion 411 extend and constitute, and it tilts and the head end bending is arcus part 4110 to Jiong type embedding part central authorities.The distance that this left and right sides arcus part is 4110 is slightly less than the width of the circuit daughter board 11 (shown in Fig. 4 B) that connector accommodates, and the edge face of breach 4101 two sides 4103,4104 of this Jiong type embedding part 410 is provided with hangnail 4105, it is penetrated in the wall of insulation shell 2 (as shown in Figure 3) for when assembling, can effectively whole Jiong type embedding part 410 be fixed, it firmly is assembled on the insulation shell 2.

Fig. 4 A, Fig. 4 B express the situation that the utility model circuit daughter board 11 is inserted in insulation shell 2 grooves 20.Shown in Fig. 4 A, after this daughter board 11 is inserted in the groove 20 of insulation shell 2, the elastic portion 411 of this elastic spring 41 is by the elasticity of itself, circuit daughter board 11 is pushed to folder post 40 1 sides, when being inserted to the location, diagram as another angle among Fig. 4 B, can know that the bottom of finding out daughter board 11 is inserted and put by terminal 3, the top then by about two the folder posts 40 clamp, simultaneously the major axis of daughter board 11 to by elastic spring 41 by two side direction central authorities contact, therefore, entire circuit daughter board 11 about and the bottom insert and put for about three clampings such as compress, except that the both sides of circuit daughter board effectively can being inserted and put, by setting above rectangular insulation shell, the scope that the circuit daughter board is inserted and put increases, and promptly inserts and puts the place and strengthens with rectangular insulation shell distance from bottom, can resist vibration effectively and avoid the instant cut-off influence to be electrically connected.
