Description

A kind of cutter for the crimping flag terminal

Technical field

The utility model relates to a kind of cutter, relates in particular to a kind of cutter for the crimping flag terminal.

Background technology

At present, the crimping moulding of flag terminal is all completed by crimp, and cutter is the very important building block of crimp as the final executor of crimping work.Yet existing cutter for the crimping flag terminal is all to adopt the mode of two-sided crimping to carry out crimping, and its compression ratio is lower, causes the electric property of flag terminal of crimping moulding relatively poor, is difficult to the result of use that reaches best.

Therefore, how to work out the cutter that can improve compression ratio is in the industry a difficult problem always.

The utility model content

For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of cutter for the crimping flag terminal, and it can improve compression ratio, improves the electric property of flag terminal.

The utility model adopts following technical scheme for achieving the above object:

A kind of cutter for the crimping flag terminal, comprise lower cutter, the cutter of going forward, upper rear cutter, two lower cutter springs, thimble and thimble springs, the bottom of lower cutter is provided with thimble groove, centre hole and two spring grooves, thimble groove and centre hole are between two spring grooves, and centre hole extends to the top of lower cutter; Go forward cutter, upper rear cutter all is placed in the top of lower cutter, and the cutter spacing of wherein going forward is directly over centre hole, and upper rear cutter spacing is in the rear side of the cutter of going forward; Two lower cutter springs are installed on respectively in two spring grooves, and stretch out from the bottom of lower cutter the lower end of twice cutter springs; Thimble comprises thimble seat and stands on thimble rod on the thimble seat top, and also be provided with the location notch that is positioned at thimble rod one side on the top of thimble seat, the thimble spring is placed between thimble groove and location notch, and centre hole is inserted in the upper end of thimble rod.

Wherein, comprise that further be used to the gear cutter that prevents from pressing quick-fried flag terminal, this gear cutter is fixed on the top of lower cutter, is positioned at a side of go forward cutter and upper rear cutter.

A kind of cutter for the crimping flag terminal that the utility model is set forth, its beneficial effect is: the utility model is by adopting the mode of single face crimping, improved the compression ratio to flag terminal, compression ratio can be up to 75%, greatly improved the electric property of flag terminal, can make flag terminal reach best result of use.

Embodiment

Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described.

Please refer to Fig. 1 to shown in Figure 3, it has demonstrated the concrete structure of the utility model preferred embodiment, a kind of cutter for the crimping flag terminal comprises lower cutter 10, the cutter 20 of going forward, upper rear cutter 30, two lower cutter springs 40, thimble 50 and thimble springs 60, wherein:

Described lower cutter 10 is used for supporting flag terminal, and the bottom of this time cutter 10 is provided with thimble groove 11, centre hole 12 and two spring grooves 13, and thimble groove 11 and centre hole 12 are between two spring grooves 13, and centre hole 12 extends to the top of lower cutter 10.

The described cutter 20 of going forward is used for the heart yearn crimping wing of crimping flag terminal, and this cutter 20 of going forward is placed in the top of lower cutter 10, and this cutter 20 of going forward be positioned at described centre hole 12 directly over.

Described rear cutter 30 is used for the insulated hull crimping wing of crimping flag terminal, and on this, rear cutter 30 is placed in the top of lower cutter 10, and on this, rear cutter 30 is positioned at the rear side of the cutter 20 of going forward.

Described two lower cutter springs 40 are used for supporting lower 10, twice cutter springs 40 of cutter and are installed on respectively in two spring grooves 13, and stretch out from the bottom of lower cutter 10 lower end of twice cutter springs 40.

Described thimble 50 is used for the below of withstanding the flag terminal heart yearn crimping wing, and this thimble 50 comprises thimble seat 51 and stands on thimble rod 52 on thimble seat 51 tops, also is provided with the location notch 511 that is positioned at thimble rod 52 1 sides on the top of thimble seat 51.

Described thimble spring 60 is used for providing actuating force for thimble 50 disengaging flag terminals reset after the flag terminal crimping is completed, and this thimble spring 60 is placed between described thimble groove 11 and location notch 511, and described centre hole 12 is inserted in the upper end of thimble rod 52.
