Description
The utility model relates to a kind of circuit board fixing device of low configuration bayonet connector, and this device is arranged on the connector, and the circuit board of being pegged graft is fixing in the axial direction, avoids causing displacement or instant cut-off because of vibration.
Early stage low configuration bayonet connector there is no the design of clamping circuit board in both sides, only rely on the terminal clamping of connector, be positioned at the lower end of entire circuit plate because of the position of terminal clamping circuit board, it is no doubt no problem to insert and put, but the steadiness that in fact inserts and puts is relatively poor, this is because terminal is to insert and put from radially (front and back), axially (about) there is no any against or fixing.During therefore actual the use, if meet vibration or bump when using, cause easily circuit board axially (about) displacement, circuit board is contacted with the connector upper terminal deviation occurs, cause instant cut-off.
Therefore, develop a kind of fixture at this defective with the further fixing of circuit board.Figure 1A, 1B are depicted as the device of No. 82206344 Taiwan patent application, the disclosed fixture 10 of this device is arranged on board in circuit board slot 110 both sides of connector 1, it mainly comprises a base portion 101 and the clamping folder 102 that joins with base portion 101, clamping folder 102 has two rubber-likes to crank arm 103,104, can clamp to insert the circuit board that clamps between the folder.Being provided with of this fixture 10 can be with the circuit board clamping, and still, in fact such clamping can not be avoided in the workplace fully because of the displacement or the instant cut-off that vibrate or bump produces circuit board.Reason is that position that fixture 10 inserts and puts the position of circuit board and terminal clamping circuit board almost at grade, be that circuit board is positioned at the lower end by the position of clamping, account for the very little part of entire circuit plate area, when therefore vibrating or clashing into, the clamping that the displacement strength that circuit board is produced by itself can break away from the lower end easily causes displacement or instant cut-off.
The purpose of this utility model is to provide a kind of low configuration bayonet connector circuit board fixing device, this fixture is being clamped in upper limb from the longer distance of connector upper terminal with circuit board, axially (about) on compress circuit board, make the upper and lower edge of circuit board and about respectively by effective clamping, resist external vibration or bump, avoid instant cut-off.
The purpose of this utility model is to realize like this, a kind of circuit board fixing device of low configuration bayonet connector promptly is provided, this fixture is by a flexible plate body bending forming, its upper limb has an excurvation cambered surface, the double wall that has the clamping circuit board along described cambered surface downwards in both sides, passageway in the double wall is connected with the insulation shell of connector, and described double wall and passageway are from the upper limb of three orientation clamping circuit boards.
The advantage of the utility model device is, owing to the upper limb clamping circuit board that described device adopts flexible plate body to hold about circuit board, has improved the stability of clamping, has strengthened circuit board and has resisted external vibration and bump, avoids the ability of instant cut-off.In addition, the flexible plate body design of the utility model is ingenious, easily processing, and production cost is low.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described, wherein:
Figure 1A is the plane graph of existing bayonet connector fixture;
Figure 1B is that existing bayonet connector fixture is arranged on the stereogram on the connector;
Fig. 2 is the stereogram of the low configuration bayonet connector circuit board fixing device of the utility model;
Fig. 3 A is that the utility model fixture is arranged on bayonet connector insulation shell both sides, and the front view of plant circuit board;
Fig. 3 B is that the utility model fixture is arranged on bayonet connector insulation shell both sides, and the cutaway view of plant circuit board;
Fig. 4 A is another embodiment stereogram of the utility model fixture;
Fig. 4 B is that another embodiment of the utility model fixture is arranged on the insulation shell and the front view of the circuit board of planting.
As shown in Figure 2, fixture 2 of the present utility model promptly bends an excurvation cambered surface 201 at flexible plate body upper limb by flexible plate body 20 bending formings, and the steering circuit plate inserts; Form double wall 202,203 downwards in both sides along cambered surface 201, this two double wall 202,203 keeps a suitable spacing, but the circuit board of this spacing clamping different-thickness.Two double walls 202,203 are sheet in the present embodiment, are directly molded on the insulation shell both sides, and its upper end cooperates cambered surface 201 outer opening, and is used for the steering circuit plate equally and inserts.By double wall 202,203 become 205 belows, passageway to form a pin 204, pin 204 both sides have overhead kick 2041, are used for assembling and insert and to prevent that this flexible plate body from deviating from when solid.Shown in Fig. 3 A, 3B, the flexible plate body of the utility model fixture 2 is planted by its pin 204 and is fixed on the insulation shell 30 of low configuration bayonet connector 3, and connector 3 both sides height are increased.In case circuit board 4 is inserted, can be by the cambered surface 201 of flexible plate body and the cambered surface of double wall 202,203 upper limbs, circuit board 4 is inserted easily, and the root edge of this circuit board 4 is connected the terminal clamping (not shown) of device 3 behind the insertion location, and the top is then folded solid by flexible plate body of the present utility model.Again referring to Fig. 3 B, can know by figure and to find out, this circuit board 4 is by from three orientation angles clampings, i.e. two double wall 202,203 and passageways 205, wherein this two passageway 202,203 is from the front and back position clamping, 205 the elasticity in this passageway by flexible plate body itself, from left and right sides lateral orientation clamping circuit board 4, so this circuit board 4 in double wall 202,203 and 205 formed three orientation, passageway by clamping effectively and firmly.
Fig. 4 A, 4B are depicted as another embodiment stereogram and front view of the utility model fixture.Among this embodiment equally by the bending of flexible plate body one go out cambered surface 201 ', double wall 202 ', 203 ' and pin 204 ', what deserves to be mentioned is, this double wall 202 ', 203 ' not be sheet, but the direct flexible plate body of punching press, with its belly towards recessed, bloat from both sides double wall 202 ', 203 ', this structure is identical with the previous embodiment effect basically, can find out that from Fig. 4 B this circuit board 4 ' equally is by clamping firmly.
More than flexible body can be stand-alone assembly, and can make by metal material.
Except the foregoing description, the also available integrated mode of fixture of the present utility model is directly made passageway, double wall and cambered surface etc. by the moulding that makes progress of the insulation shell both sides of connector, and this can decide according to the material that this flexible plate body adopted.
