[embodiment]
Please refer to shown in Fig. 1, the utility model bayonet connector 100 can be installed to (not shown) on printed circuit board (PCB), and in order to grafting docking electronics module (not shown), thus carry out Signal transmissions at printed circuit board (PCB) with docking between electronics module; Described bayonet connector 100 comprises the insulating body 1 of lengthwise, the several conducting terminals 2 be immobilizated in insulating body 1, is immobilizated in insulating body 1 at least one retaining piece 3 be fixed on printed circuit board (PCB) and a pair latch 4 being articulated in insulating body 1 two ends.
Please refer to shown in Fig. 1, Fig. 2, described insulating body 1 is provided with the two side 11 extended along longitudinally, the turriform portion 12 of protruding setting relative to sidewall, this turriform portion 12 is connected to this sidewall 11 lengthwise two ends, thus this insulating body 1 forms the central slot 101 extended along longitudinally, for the above-mentioned docking electronics module of collecting; Described insulating body 1 has protruded out knob of key 110 in central slot 101, for coordinating the corresponding groove (not shown) arranged in above-mentioned docking electronics module, can prevent anti-plug; Described insulating body 1 also has slot 101 central with this and is connected and the several terminals groove 102 of accommodating above-mentioned conducting terminal 2, each conducting terminal 2 is provided with the contact site 21 protruding into central slot 101, the weld part 22 extended from contact site 21 outside insulating body, is electrically connected for above-mentioned printed circuit board (PCB); Contact site 21 one-tenth two row of conducting terminal 2, be arranged in two side 11 respectively, and the weld part 22 of described conducting terminal 2 is divided into four rows, to arrange more conducting terminal 2 in the limited areal on printed circuit, save the space that bayonet connector 100 is shared on a printed circuit.The grasping plate portion 31 that described retaining piece 3 comprises the holding parts (not shown) be immobilizated in insulating body, extends from holding parts, thus strengthen bayonet connector 100 on a printed circuit fixing.
Please with further reference to shown in Fig. 3, described latch 4 comprises main part 40, main body 40 protrude out arrange and the shaft 41 be articulated with insulating body, be arranged at main part 40 one end may extend into central slot 101 move back card division 42, the operating portion 43 being arranged at main part 40 other end, the buckle portion 44 being positioned at operating portion 43 opposite side and main body 40 protrude arrange hold protuberance 45; Described turriform portion 12 has the mounting groove 121 of collecting latch 4, described latch 4 is articulated in this mounting groove 121, described turriform portion 12 is provided with the pivoted hole 123 of corresponding collecting shaft 41 and guides shaft 41 to be fit into the guide portion 122 of pivoted hole 123, in installation process, the shaft 41 of latch 4 is assembled into pivoted hole 123 along guide portion 122, latch 4 can be made to rotate relative to insulating body 1 in portion 41 around the shaft, and easy to assembly.On longitudinally, described latch 4 also has the outwardly open fluting 46 of main body 40, and this fluting 46 is stepped, can prevent latch 4 buckling deformation in forming process, also can ensure the structural strength of this latch 4.
Pull described operating portion 43, latch 4 rotates, and can realize the swing between open mode or snap close state, when needing to insert docking electronics module, when outwards pulling operating portion 43, the buckle portion 44 of this operating portion 43 opposite side gets out of the way space, now latch 4 is positioned at open mode, docking electronics module is allowed to insert, in insertion process, this docking electronics module applies active force in moving back on card division 42, until insert put in place after, inwardly pull described operating portion 43, buckle portion 44 moves to central slot 101 place with operating portion, can be held in recess (not shown) corresponding to docking electronics module, now latch 4 is positioned at snap close state, so that the firm snap close of electronics module will be docked in bayonet connector.When needs exit docking electronics module, outwards pull operating portion 43, move back card division 42 towards motion in central slot 101, exit with pushing tow docking electronics module.
The main part 40 of latch 4 corresponds to aforementioned stepped fluting 46 and is divided into the first main part 401 and the second main part 402, and form a stage portion in the junction of first, second main part 401,402, this second main part 402 protrudes out to shaft 41 from described junction and arranges a pair limiting section 48, this limiting section 48 and shaft 41 interval are arranged, in addition, the outside that protuberance 45 is positioned at described limiting section 48 and described shaft 41 place virtual line is held described in.The guide portion 122 in turriform portion 12 is provided with the spacing inclined-plane 14 coordinating with described limiting section 48 to prevent latch 4 from excessively rotating.When exiting docking electronics module, outwards pull operating portion 43, limiting section 48 follows the spacing inclined-plane of main part 40 rotation direction 14 until limiting section 48 is resisted against spacing inclined-plane 14, thus suppresses latch 4 excessively to rotate.At the longitudinally perpendicular to insulating body transversely, the height of limiting section 48 is not more than the height of described stage portion.On longitudinally, the width of guide portion 122 opening part is greater than the diameter of pivoted hole 123, enters described pivoted hole 123 to guide shaft 41 better.Particularly, described guide portion 122 comprises the vertical guide surface 1220 connecting pivoted hole 123 and the spacing inclined-plane 14 be connected with described vertical guide surface 1220, the length of described vertical guiding face 1220 is greater than the radius of described pivoted hole 123, when installing described latch 4, described shaft 41 is first guided into the vertical boot section of described vertical guide surface 1220 formation via described spacing inclined-plane 14, described pivoted hole 123 is guided into again, to give full play to the guide function of described guide portion 122 via described vertical guide surface 1220.
Please further shown in composition graphs 4, the both sides, card division 42 of moving back of latch 4 are provided with a pair limiting wall 47, and described in move back card division 42 width and be less than described central slot 101 width, when limiting section 48 abuts with spacing inclined-plane 14, move back card division 42 and stretch into central slot 101, and limiting wall 47 is held in the end wall 15 of two side 11 along longitudinally two ends, to add the excessive rotation of high inhibition latch 4 simultaneously.
As can be seen here, the mode that the utility model bayonet connector 100 adopts limiting section 48 to coordinate with spacing inclined-plane 14 limits latch and excessively rotates, and limiting section 48 and shaft 41 are provided separately, even if also shaft 41 can not be had influence on because improper operation makes limiting section 48 damage, make bayonet connector still can carry out the operation of pintle hook lock/move back card, add the reliability of bayonet connector.
In sum, these are only preferred embodiment of the present utility model, scope of the present utility model should do not limited with this, namely every simple equivalence change done according to the utility model claims and utility model description with modify, all should still belong in scope that the utility model patent contains.
