[embodiment]

Below in conjunction with the drawings and specific embodiments the utility model bayonet connector is described further.

Please refer to Fig. 1 to shown in Figure 7, the utility model bayonet connector comprises a lengthwise type insulating body 10, plurality of conductive terminals (not icon) and two bayonet units 20 in order to electronic cards (not icon) is connected on the circuit board (not icon).

Described insulating body 10 comprises a pair of

long limit wall

11,11 on limit wall is provided with central slot 12 along long axis direction, central authorities slot 12 both sides are provided with two row and form the terminal accommodation holes (not icon) that is communicated with central slot, conducting terminal is contained in the described terminal accommodation holes, be provided with resettlement section 14 at the two ends of insulating body 10, to accommodate bayonet unit 20, this resettlement section 14 is provided with a two side 140 and a reinforced wall 141, and the outside, upper end of described two side 140 is provided with grab 148 and holds this bayonet unit 20 to match with bayonet unit 20; Described reinforced wall 141 is connected between the two side 140, it can strengthen the intensity of resettlement section 14, the location of being convenient to bayonet unit 20 reaches fixing, the firm button of electronic cards is held in this bayonet connector, the end extension of described reinforced wall 141 is provided with stop surface 1411, this stop surface 1411 is towards insulating body direction and the downward inclined-plane that extends, stop surface 1411 lower ends 1412 are perpendicular, it can contact bayonet unit 20 to limit its rotation amount this stop surface 1411, on the centre position of 14 inboard, resettlement section, be provided with and articulate axis hole 145, to articulate bayonet unit 20 near the inside lower end portion of sidewalls 140.

Bayonet unit 20 is articulated in the resettlement section 14 as described in Figure, comprise main part 200 and the ejection part 201 that extends by main part 200 ends, to eject the electronic cards of butt joint, and this ejection part 201 is provided with a groove 2011, this groove 2011 has the width greater than the described electronic cards thickness that cooperates with it, can partly accept electronic cards, so that its better location, these groove 2011 parts extend to the end of main part 200 to increase its loaded area, in addition, these groove 2011 all right these bayonet units 20 of reinforcement, the intensity of reinforcement ejection part 201.Described main part 200 comprises the front end face 202 that the one side relative with central slot 12 is provided with, it can cooperate with stop surface 1411 with restriction bayonet unit 20 rotation amounts, main part 200 also is provided with by front end face 202 and extends back and the dual-side 203 that forms in addition, the lower end of this side 203 is provided with rotating shaft 209, match in order to pivot joint axis hole 145 with 14 inboards, resettlement section, and be not to be connected fully but to leave the space between described dual-side 203 and the front end face 202, further increase the mechanical elasticity of this bayonet unit 20 with this; Being provided with the ejection part 201 relative other ends by main body 200 extends forward and convexes with the clamping part 207 that holds electronic cards, this clamping part 207 is located at the top of front end face 202, this clamping part 207 continues extension and is formed with a tabular connecting portion 208, the horizontal width of this connecting portion 208 is greater than the horizontal width of clamping part 207, at the dual-side 203 of main part 200 the other end with respect to rotating shaft 209, be that the top of described side 203 stretches out and is provided with outstanding operating portion 205, can make bayonet unit 20 break away from insulating body 10 by this operating portion 205 of offset operation, this operating portion 205 roughly is to become oval recess, approximate human body auricle shape, be convenient to the extruding of two artificial fingers, downside at two operating portions 205 is provided with a limiting section 204 that matches with the grab 148 of resettlement section 14, this limiting section 204 comprises a recess 2041 and a lug 2042, this recess 2041 cooperates with grab 148 can limit bayonet unit 20 motion in the horizontal direction, be positioned at the below of grab 148 after these lug 2042 assemblings, cooperate with grab 148 and can limit the motion of bayonet unit 20 at vertical direction, on the upper end of two operating portions 205, be provided with the hole clipping 206 that matches with described connecting portion 208, but the two ends of these hole clipping 206 limiting sections 208 and make clamping part 207 and operating portion 205 mechanical connections can be moved it under the traction of two operating portions 205.

During operation, when being in open state, bayonet unit 20 can insert electronic cards, the bayonet unit closure, by the acting in conjunction of clamping part 207 with groove 2011, closely be connected electronic cards in the bayonet connector, and match with limiting section 204 motion of spacing bayonet unit 20 of grab 148, so, if will take out electronic cards, must a little firmly push two operating portions 205, make limiting section 204 break away from the restriction of grab 148, and outwards move simultaneously, bayonet unit 20 is promptly to inner rotary, this moment, clamping part 207 withdrawed from the groove (not shown) with matching that electronic cards is provided with, discharge electronic cards, ejection part 201 upwarps simultaneously, thereby electronic cards is ejected, certainly on the relative position of bayonet unit main part 200 and central slot 12, be provided with cooperate with stop surface 1411 to limit the front end face 202 of bayonet unit rotation amount, and stop surface 1411 is bigger with the contact area of front end face 202, so bayonet unit can not break away from insulating body because of stressed excessive excessively the rotation, in sum, this uses novel bayonet connector, electronic cards will be operated the operating portion that links to each other with clamping part by extruding owing to trip, make limiting section 204 break away from the restriction of grab 148, so, need through manually-operated bayonet unit, fasten firmly, not manual operation can not occur the electronic cards outage substantially or break away from and situation that can't operate as normal.
