Embodiment
In order to make the technical solution of the utility model clearly, below in conjunction with accompanying drawing, crimping blade of the present utility model is described in further detail.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.
See Fig. 3 to Fig. 5, as shown in Figure 3, crimping blade of the present utility model, for the crimping of puncture type terminal, comprise and wait to crimp the open slot 1 of puncture type terminal for holding, the inwall of the bottom land of open slot 1 is two adjacent cambered surfaces, is respectively the first cambered surface 11 and the second cambered surface 12, and on the opening direction of open slot 1, between the center of circle of the first cambered surface 11 and the center of circle of the second cambered surface 12, there is difference in height.Namely compared to general crimping blade, the first cambered surface 11 of crimping blade of the present utility model and the second cambered surface 12 asymmetric.In the present embodiment, the center of circle of the first cambered surface 11 is higher than the center of circle of the second cambered surface 12, and in other embodiments, the center of circle of the first cambered surface 11 also can lower than the center of circle of the second cambered surface 12.
In the process of puncture type terminal crimping, because the center of circle of the second cambered surface 12 is lower than the center of circle of the first cambered surface 11, therefore, the puncture type terminal at the second side, cambered surface 12 place first crimps, crimp after the puncture type terminal at the first side, cambered surface 11 place, what the two ends of puncture type terminal were replaced fits together, instead of all presses to middle enamelled wire, avoids the hidden danger that middle enamelled wire is pressed down.In the present embodiment, the first cambered surface 11 is arranged on the right-hand member of crimping blade, and the second cambered surface 12 is arranged on the left end of crimping blade, therefore, the left end of puncture type terminal is first crimped, and is crimped after the right-hand member of puncture type terminal, and the right-hand member of puncture type terminal is overlapped on the left end of puncture type terminal.In other embodiments, the position of the first cambered surface 11 and the second cambered surface 12 can also be other.
Difference in height is there is by the center of circle of two cambered surfaces on the inwall of the bottom land of open slot, the i.e. asymmetrical design of the first cambered surface and the second cambered surface, like this, owing to there is difference in height between the center of circle of the first cambered surface and the center of circle of the second cambered surface, the puncture type terminal of the side, cambered surface place making the center of circle lower first crimps, crimp after the puncture type terminal of the side, cambered surface place that the center of circle is higher, what the two ends of puncture type terminal were replaced fits together, the two ends avoiding puncture type terminal break the hidden danger of intermediate coat envelope curve, reduce the fraction defective of puncture type terminal crimping, improve the quality of puncture type terminal crimping.
As a kind of embodiment, the difference in height between the center of circle of the first cambered surface 11 and the center of circle of the second cambered surface 12 is 1 ~ 1.5 times of the wall thickness of puncture type terminal to be crimped.In the present embodiment, the difference in height between the center of circle of the first cambered surface 11 and the center of circle of the second cambered surface 12 is H, and the value of H is relevant with waiting the wall thickness T crimping puncture type terminal, preferably, and H=(1 ~ 1.5) T.In other embodiments, the value of H can also be other possible numerical value.
More preferably, the sidewall 13 of open slot 1 is arcwall face, and the longitudinal section of open slot 1 is horn-like.More preferably, crimping blade is also provided with installing hole 2.In the present embodiment, installing hole 2 is arranged on the blade of crimping blade.More preferably, relative with open slot 1 on crimping blade one end is provided with the U-type groove 3 for locating.In the present embodiment, the sidewall of U-type groove 3 is arcwall face, and the bottom surface of U-type groove 3 is also arcwall face.
Crimping blade of the present utility model, difference in height is there is by the center of circle of two cambered surfaces on the inwall of the bottom land of open slot, the i.e. asymmetrical design of the first cambered surface and the second cambered surface, like this, owing to there is difference in height between the center of circle of the first cambered surface and the center of circle of the second cambered surface, the puncture type terminal of the side, cambered surface place making the center of circle lower first crimps, crimp after the puncture type terminal of the side, cambered surface place that the center of circle is higher, what the two ends of puncture type terminal were replaced fits together, the two ends avoiding puncture type terminal break the hidden danger of intermediate coat envelope curve, reduce the fraction defective of puncture type terminal crimping, improve the quality of puncture type terminal crimping.
The above embodiment only have expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
