Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is done concrete introduction.
Referring to figs. 1 through Fig. 2, splicing ear of the present invention mainly comprises: clamping terminal 1 and inserted sheet 5.
Wherein, clamping terminal 1 is formed with integrally formed 2, two intermediate plates of two intermediate plates 2 and constitutes connection through connector 3, need to prove that whole clamping terminal 1 is one of the forming, and promptly intermediate plate 2 and connector 3 are one of the forming.
For effective clamping can be provided, two intermediate plates 2 stretch out to the homonymy of connector 3, and all distance is contracted to minimum clamp segment a to the part that intermediate plate 2 stretches out connector 3 gradually to being bent to form each other near each other direction.The major part of this section for when inserted sheet 5 inserts, being used for contacting and clamping with inserted sheet 5; Two intermediate plates 2 at this place can contact; That is to say that the distance between them is zero; Can have certain distance between them, but this distance should not cause clamping not tight greater than inserted sheet 5 corresponding sizes yet.
After having formed clamp segment a; Minimum distance with clamp segment a is a boundary; Intermediate plate 2 all is bent to form segregation section b to away from each other direction away from the part of connector 3 (promptly to figure in right-hand), is provided with the end construction that is used for when inserting, strutting two intermediate plates 2 in the end of segregation section b.
Shown in seeing figures.1.and.2; The part that intermediate plate 2 is connected with connector 3 is as the fulcrum of lever; The process of inserting inserted sheet 5 is with this place and pries open the process of intermediate plate 2 extensions as fulcrum, and we know that clamp segment a opens up into certain degree if desired, and the power that applies at the end construction place so is necessarily less than the power that applies at clamp segment a place; Because the arm of force at end construction place is greater than the arm of force at clamp segment a place; So producing under the situation of identical moment, it is little to apply power at the end construction place, the strength that promptly contacts the insertion that struts clamp segment a with end construction with inserted sheet 5 is less than the strength that directly is inserted into the insertion among the clamp segment a.When inserting, promptly obtain the space that clamp segment a can make inserted sheet 5 get into wherein with less power; When clamping, same principle, the clamping force at clamp segment a place is bigger under the effect of intermediate plate 2 self.When needs are extracted, because the clamp segment a of intermediate plate and the bending structure of segregation section b when inserted sheet 5 withdraws from, may run into the obstruction of big frictional force; Because frictional force is directly proportional with the strength of clamping, extract for easier, like Fig. 1 or shown in Figure 2; Insert sheet and be formed with the convexity 6 that is used to strut end construction, so, when extracting the inserted sheet 5 of certain-length a little; Protruding 6 promptly contact with end construction, its whole intermediate plate 2 are all strutted the part that inserted sheet 5 residues are not extracted; Then no longer contact with clamp segment a, frictional force descends, and is more convenient for extracting.
So, strut and clamp two function branches and be clipped to end construction and two different portions of clamp segment a, overcome original defective that when the clamping force of reliable connection can be provided, is difficult to plug through splitting.
In order to realize above-mentioned target better, end construction can adopt following two preferred versions.
As shown in Figure 1, the concrete form of end construction is the roller 4 that is rotationally connected with intermediate plate 2, and in order to realize being rotationally connected, two of the termination separation of intermediate plate 2 are rolled into axle sleeve, and the two ends of roller 4 form and are placed on the rotating shaft in the axle sleeve.Roller 4 can roll, and makes things convenient for inserted sheet 5 to insert, and reduces the resistance that inserts.
As shown in Figure 2, as a kind of reduction procedure, end construction is the insertion section c that segregation section b end is extended and is bent to form, and two are inserted section c and form the insertion mouth that mutual distance increases gradually.In this scheme, it constitutes the insertion mouth that opens wide and makes things convenient for inserted sheet 5 to get into, and the stress point that contact can be provided and then strut.
As a kind of preferred version, two intermediate plates 2 and on end construction be the mirror image symmetry; And the outline of intermediate plate is level and smooth curve.
In addition, the material that constitutes clamping terminal 1 should have certain elasticity, and as a kind of preferred version, clamping terminal 1 is processed for the rubber-like metal material.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop in protection scope of the present invention.
