The utility model discloses the slip-off preventing crocodile clip that a kind of plug in folder is dual-purpose, comprise by two mutually hinged jig arm of rotating shaft, in rotating shaft, cover has the torsion spring supporting jig arm, rotating shaft is welded with wire, the inwall of described two jig arm front ends be provided with match each other clip tooth, one of them jig arm front end inwall on be vertically fixed with pilot pin; The outer wall of described two jig arm rear ends is laterally evenly equipped with some tread plates.The series connection of copper sheet type and screw-type two kinds of terminals can be met, the reliable difficult drop-off of fixed form, improve the versatility of connecting line.
Description
Technical field
The utility model relates to a kind of lead accumulator technical field, is specifically related to the slip-off preventing crocodile clip that a kind of plug in folder is dual-purpose.
Background technology
In order to enhance productivity, the charging modes of lead accumulator is generally get up to charge by many serial battery, according to the difference of battery terminal, selects different connecting lines to connect.Directly terminal is clamped with crocodile clip, if there is External Force Acting crocodile clip to be easy to come off in charging process during the charging of copper sheet type terminal; And need first in terminal, to screw in auxiliary bolt before the charging of screw-type terminal, and then clamp auxiliary bolt with crocodile clip and charge, screw-in and the dismounting of auxiliary bolt are wasted time and energy, and add operational sequence.
Existing license notification number is " the battery wire folder that a kind of plug in folder is dual-purpose " of CN203747064U, and crocodile clip jig arm is designed to U-shaped shell fragment, and it is applicable to the charging of copper sheet type and screw-type terminal.But U-shaped shell fragment needs to select expensive highly elastic material, adds and makes cost; In addition, after original jagged jig arm is changed to U-shaped shell fragment, weaken the effect of clamping, easily come off during folder copper sheet type terminal, and due to U-shaped shell fragment volume larger, must U-shaped shell fragment jig arm be placed on above terminal during folder copper sheet type terminal, not meet the operating habit of staff, add operation easier.
Therefore, need to design the dual-purpose crocodile clip of a kind of volume plug in folder that is little and easy manufacture, two kinds of form terminal battery series connection can be met, improve the versatility of connecting line.
Summary of the invention
The utility model overcomes existing defect, provides the slip-off preventing crocodile clip that a kind of plug in folder is dual-purpose, can meet the series connection of copper sheet type and screw-type two kinds of terminals, the reliable difficult drop-off of fixed form, improves the versatility of connecting line.
The utility model is achieved through the following technical solutions:
The slip-off preventing crocodile clip that a kind of plug in folder is dual-purpose, comprise by two mutually hinged jig arm of rotating shaft, in rotating shaft, cover has the torsion spring supporting jig arm, rotating shaft is welded with wire, the inwall of described two jig arm front ends be provided with match each other clip tooth, one of them jig arm front end inwall on be vertically fixed with pilot pin; The outer wall of described two jig arm rear ends is laterally evenly equipped with some tread plates.
The further improvement project of the utility model is, described clip tooth is the one section zigzag projection of continuous arrangement in described jig arm front inner wall, and described pilot pin is positioned at the middle part of continuously arranged projection.
The utility model further improvement project is, described pilot pin coordinates grafting with the through hole of copper sheet type terminal, and the height that described pilot pin exceeds clip tooth tooth top is consistent with the degree of depth of shape copper sheet type terminal through-hole.
The utility model further improvement project is, when the inwall of described two jig arm rear ends offsets, its outer wall coordinates clamping with the screwed hole of screw-type terminal.
The utility model further improvement project is, the cross section of described tread plate is semicircle, and the diameter of semicircle tread plate is 1-2mm.
Compared to the prior art the utility model has the following advantages:
The utility model increases in the jig arm front inner wall of crocodile clip the pilot pin coordinating grafting with copper sheet type terminal, while during use, clip tooth clamps copper sheet pilot pin insert copper sheet through hole in spacing, even if be subject to External Force Acting pilot pin also can pin terminal, prevent crocodile clip from coming off, fixed form is reliable; When retaining thread formula terminal, extruding jig arm rear end makes the inwall of rear end fit to reach maximum elastic force, then rear end is inserted in the screwed hole of terminal, jig arm rear end struts and connects and fixes with screw thread hole wall in screwed hole, the outer wall of jig arm rear end is provided with the anti-slip veins suitable with dimension of inner screw thread, and anti-slip veins and internal thread cooperatively interact and can prevent crocodile clip from coming off; The utility model manufacturing structure is simple, and volume is little, is applicable to the storage battery of copper sheet type and screw-type terminal, highly versatile, easy and simple to handle, effectively can prevent accidental.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is the schematic diagram that the utility model coordinates with copper sheet type terminal.
Fig. 3 is the schematic diagram that the utility model coordinates with screw-type terminal.
Wherein: 1 jig arm, 2 pilot pins, 3 rotating shafts, 4 torsion springs, 5 tread plates, 6 clip tooths, 7 wires, 8 copper sheet type terminals, 9 screw-type terminals.
Embodiment
As Fig. 1, 2, the slip-off preventing crocodile clip that a kind of plug in folder shown in 3 is dual-purpose, comprise by two mutually hinged jig arm 1 of rotating shaft 3, in rotating shaft 3, cover has the torsion spring 4 supporting jig arm 1, rotating shaft 3 is welded with wire 7, the inwall of two jig arm 1 front ends is provided with the clip tooth 6 matched each other, the inwall of one of them jig arm 1 front end is vertically fixed with pilot pin 2, clip tooth 6 is the one section zigzag projection of continuous arrangement in jig arm 1 front inner wall, pilot pin 2 is positioned at the middle part of continuously arranged projection, the structure of front end is in order to fixed copper blade terminal 8, pilot pin 2 coordinates grafting with the through hole of copper sheet type terminal, even if be subject to External Force Acting pilot pin 2 also can pin terminal, prevent crocodile clip from coming off, wherein, the height that pilot pin 2 exceeds clip tooth 6 tooth top is consistent with the degree of depth of copper sheet type terminal through-hole, can ensure that two jig arm 1 front ends can closely be engaged.
