Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Shown in composition graphs 1 and Fig. 2, be the present invention one preferred embodiment, a kind of belt line spring terminal 10, comprises belt crimp type terminal 100 and line spring contact 200.Line spring contact 200 and belt crimp type terminal 100 are connected together, and line spring contact 200 is column, and column is circumference line contact with outside contact.
As shown in Figures 3 to 5, line spring contact 200 comprises inner sleeve 203, rear cover 201, protheca 205 and some line spring silks 204.One end that rear cover 201 is linked in inner sleeve 203 is fixed by interference fit, and protheca 205 is linked in the other end of inner sleeve 203 and is fixed by interference fit, and protheca 205 and rear cover 201 contact.Some line spring silks 204 are around in inner sleeve 203, and be uniformly distributed on the excircle of inner sleeve 203, one end of line spring silk 204 is fixed by the interference fit of rear cover 201 and inner sleeve 203, and the other end of line spring silk 204 is fixed by the interference fit of protheca 205 and inner sleeve 203.The interface that protheca 205 and rear cover 201 contact along the circumferential direction is evenly distributed with some pressure points 202.Pressure point 202 is formed by flow of metal, protheca 205 and rear cover 201 can be fixed in inner sleeve 203, be not easy to come off.
Protheca 205 or inner sleeve 203 are provided with the cylinder step 207 more smaller than the diameter of protheca 205 or inner sleeve 203 away from one end of belt crimp type terminal 100, and as shown in Figures 2 and 3, this cylinder step 207 can play the effect of protection.
One end that rear cover 201 is connected with belt crimp type terminal 100 can arrange circumferentially equally distributed crimp groove 206, as shown in Figure 2.Crimp groove 206 is formed by rear cover 201 stamped metal distortion, can be fixed on the belt crimp type terminal 100 of back segment by the line spring contact 200 of leading portion, difficult drop-off, and ensures that electric conductivity is good.
As shown in Figure 6, for the second structural representation of line spring contact 200 ', the difference of itself and Fig. 3 illustrated embodiment is mainly, line spring contact 200 ' in the present embodiment eliminates the cylinder step be arranged on protheca 205 ' one end, still comprises inner sleeve 203 ', protheca 205 ', rear cover 201 ' and some line spring silks 204 ' in it.
