Specific embodiment

It is described further referring to figs. 1 to Fig. 4 USB electric connectors embodiments a kind of to the utility model.

A kind of USB electric connectors, shell 1 and USB female seats 2, the USB female seats 2 include horizontal seat 20 and vertical seat 21, the horizontal stroke Seat 20 and vertical seat 21 are mutually perpendicular to shape angle in 90 °, and the relative other end being connected with horizontal seat 20 of the vertical seat 21 is provided with Fixed plate 22, the fixed plate 22 is parallel to each other with horizontal seat 20, the card chamber 23 that formation is embedded for shell 1, is set on the horizontal seat 20 There is translot 200, the vertical seat 21 is provided with pod 210, and the translot 200 is connected with pod 210, and the pod 210 is just Top is provided with draw-in groove 211, and the draw-in groove 211 is connected with pod 210, and connection terminal 24, the company are provided with the translot 200 Connecting terminal 24 includes the first shell fragment terminal 240 and the second shell fragment terminal 241, and one end of the first shell fragment terminal 240 is embedded at In translot 200, the other end is embedded in pod 210 and extends outside pod 210, and one end of the second shell fragment terminal 241 is embedding Set in gap in translot 200 and with the first shell fragment terminal 240, the other end is embedded in draw-in groove 211, second shell fragment Terminal 241 is provided with the portion of arching 242, and the portion 242 of arching extends outside translot 200, during USB male joint insertion USB female seats 2, institute The portion 242 of arching stated on the second shell fragment terminal 241 moves towards the bottom of translot 200, until being offseted with the first shell fragment terminal 240 Touch, USB electric connectors are in open mode, when USB male joint leaves USB female seats 2, arching on the second shell fragment terminal 241 Towards motion at the opening of translot 200, until being disconnected with the conflict of the first shell fragment terminal 240, USB electric connectors are in and close in portion 242 Closed state.

When USB male joint inserts USB electric connectors, USB male joint can extrude the portion 242 of arching on the second shell fragment terminal 241, So that portion 242 of arching moves towards the bottom of translot 200, inconsistent with the first shell fragment terminal 240, now USB electric connectors are just In "on" position, just electrical equipment can be charged；Conversely, USB male joint is extracted into USB electric connectors, the second shell fragment terminal 241 On the extruding force that is subject to disappear, return to original state, the connection on the first shell fragment terminal 240 and the second shell fragment terminal 241 Will disconnect so that circuit is off, in the case of not use, improve security performance, while also functioning to protection The effect of circuit, greatly prolongs service life, and Improving The Quality of Products.

The L-shaped setting of the second shell fragment terminal 241, one end connects portion 242 of arching, and another card that is provided with sets piece 243, institute State card and set the bending of piece 243 with the second flexure strip in 90 ° of settings, the card sets piece 243 and is provided with and is embedded for the first shell fragment terminal 240 Groove 244.

Card sets the setting of piece 243 so that it is better that the second shell fragment terminal 241 is fixed in USB female seats 2, and card sets piece The setting of 243 upper grooves 244, lifting with the first shell fragment terminal 240 cooperate accuracy so that circuit be in disconnect or What is connected is better, more precisely.

The cavity wall in the card chamber 23 that the USB female seats 2 are embedded for shell 1 is provided with fixture block 25, and the shell 1 is female with respect to USB One end of seat 2 is provided with the bayonet socket 10 being adapted with fixture block 25.

Fixture block 25 and the setting of bayonet socket 10, cause the connectivity robustness of USB female seats 2 and shell 1 more preferably, lift product matter Amount.

The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to Go out, for those skilled in the art, some improvement under the premise of the utility model principle is not departed from and Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
