Description

Technical Field

[0001] The utility model relates to a wire stripping tool, in particular to a multi-lead synchronous cutting and stripping tool for lead connectors. Background Art

[0002] Connectors are widely used in various industries. Connectors with leads are particularly common in various potentiometers (sensors). As standard products on the shelf, connectors with leads have a longer initial lead length to facilitate the needs of different lead lengths. Users cut the lead length to the appropriate length according to actual needs. After cutting, the outer plastic protective layer of the lead end needs to be removed (i.e., stripping) to facilitate subsequent welding or testing processes.

[0003] In practical applications, it is often necessary to cut the multiple leads of leaded connectors to different lengths. For example, a common leaded connector has three leads: red, white, and blue. The initial length of the three leads is 100 mm. However, in actual use, the length of the blue lead is required to be 73.5 ± 0.5 mm, the length of the white lead is required to be 75.5 ± 0.5 mm, and the length of the red lead is required to be 77.5 ± 0.5 mm. This requires that the multiple leads be cut and stripped separately to meet application requirements.

[0004] For the multiple leads of the above-mentioned connector with leads, there are two main traditional methods of cutting and stripping: the first is to first use wire cutters to cut the multiple leads according to the corresponding lengths, and then use ordinary wire strippers to strip the ends of the multiple leads separately. This method has the following defects: first, it is necessary to measure the lengths of the multiple leads separately, which is not only difficult to accurately control the lead lengths, but also has low measurement efficiency. Second, it is easy to damage the wire core, which poses a hidden danger to subsequent use; the second is to first use wire cutters to cut the multiple leads according to the corresponding lengths, and then use hot stripping pliers to strip the ends of the multiple leads separately (that is, using instantaneous high temperature stripping generated by resistance wire). This stripping method has the following defects: first, it is necessary to measure the lengths of the multiple leads separately, which is not only difficult to accurately control the lead lengths, but also has low measurement efficiency. Second, compared with ordinary wire strippers, the stripping efficiency of hot stripping pliers is lower.

[0005] In summary, for applications where leaded connectors require multiple leads of different lengths, the above-mentioned traditional cutting and stripping methods have the disadvantages of difficult to accurately control the lead length and low efficiency. This disadvantage is particularly prominent for the application of batch products. Utility Model Content

The area between the inner wall of one end of the first mounting groove close to the lead separator 9 and the movable plate 5 is used to install the lead connector 7.

[0026] In order to facilitate the limited movement and fixation of the movable plate 5 in the X direction, the movable plate 5 is provided with a vertically penetrating and laterally strip-shaped movable plate strip-shaped through hole (not marked in the figure).

The lead separator 9 is provided with a plurality of lead grooves 12, and the plurality of lead grooves 12 are arranged in sequence in a horizontal direction perpendicular to the X direction.

[0029] In order to facilitate the installation of the lead separator 9 and the lead collection member 13 and to keep the lead 8 always on the top of the base plate 1 and maintain the same horizontal plane to improve the length control accuracy, and at the same time, in order to adjust the relative position of the lead separator 9 on the base plate 1 to better separate and guide the lead 8, a second installation groove (not marked in the figure) is provided on the top of the base plate 1 at a position corresponding to the lead separator 9 and the lead collection member 13. The lead separator 9 and the lead collection member 13 are both placed in the second installation groove, and the middle part of the upper part of the lead separator 9 is concave to form a middle lead groove 12 The lead groove 12 is a straight groove and its length direction is the X direction. The other lead grooves 12 are straight grooves or non-linear grooves with openings at the bottom, top or side (depending on the specific needs, the figure shows a straight groove with an opening at the lower side). The lead separator 9 is provided with a vertically penetrating and laterally strip-shaped separator strip through hole 11. The horizontal length direction of the separator strip through hole 11 is parallel to the X direction. The screw of the separator positioning screw 10 passes through the separator strip through hole 11 from top to bottom and is connected to the corresponding screw hole (not visible in the figure) on the base plate 1.

[0030] In order to facilitate the installation of the lead collection piece 13 and quickly collect multiple leads 8 together, the lead collection piece 13 is a strip plate and is installed on the base plate 1 by vertical mounting screws (not marked in the figure). The middle part of the upper part of the lead collection piece 13 is provided with a guide groove 15 that penetrates in the X direction and is open on the top and is used for multiple leads 8 to pass through.

[0031] In order to facilitate the rapid installation of the lead positioning member 14 , the lead positioning member 14 is a strip-shaped pressure plate and is installed on the base plate 1 through vertical mounting screws (not marked in the figure).

[0032] like Figure 1 and Figure 2As shown, when in use, first push the movable plate 5 by hand to move it toward the direction close to the fixed plate 2, then place the lead connector 7 in the area between the inner wall of one end of the lead separator 9 in the first installation groove and the movable plate 5, then release the movable plate 5, and under the action of the compression spring 4, the movable plate 5 presses the lead connector 7 against the inner wall of one end of the lead separator 9 in the first installation groove to complete the installation of the lead connector 7, and then place multiple (three in the figure) lead wires 8 in the multiple lead grooves 12 on the lead separator 9, and according to the requirements of each lead wire 8, The length of the lead wire 8 is placed in the corresponding lead wire groove 12, the shortest lead wire 8 is placed in the middle straight lead wire groove 12, the longest lead wire 8 is placed in the lead wire groove 12 farthest from the middle lead wire groove 12, and the other leads 8 are placed accordingly; after passing through the lead wire separator 9, the multiple leads 8 are led together to the entrance end of the guide groove 15 of the lead wire collection part 13 and pass through the guide groove 15, and then placed together under the lead positioning part 14 and pressed and positioned by the lead positioning part 14, thus completing the installation of the multiple leads 8 with the lead connector 7. Then, the multiple leads 8 can be cut synchronously at one time by corresponding tools such as wire cutters. When cutting, the strip cutting indicator groove 17 is used as a basis so that the cutting part and the strip cutting indicator groove 17 are located in the same straight line; after cutting, the multiple leads 8 are stripped by corresponding wire strippers according to actual needs. Both hot stripping pliers and laser wire stripping machines can strip multiple leads 8 synchronously at one time, which significantly improves efficiency.

[0033] like Figure 2As shown, the principle of achieving precise length control of each lead 8 by the lead separator 9 is as follows: four horizontal virtual straight lines A, B, C, and D are set, which are parallel to each other and perpendicular to the X direction. The position where the multiple leads 8 are bent in the inlet end of the guide groove 15 is located on the A line, the position where the multiple leads 8 are bent in the outlet end of each lead groove 12 on the lead separator 9 is located on the B line, the position where the multiple leads 8 are bent in the inlet end of each lead groove 12 on the lead separator 9 is located on the C line, and the position where the multiple leads 8 with the lead connector 7 start to bend is located on the D line. The lengths of the leads 8 between the strip cutting indicator groove 17 and the A line and between the B line and the C line are the same. The lengths of the leads 8 between the A line and the B line and between the C line and the D line are different. The actual length of each lead 8 is the length between the strip cutting indicator groove 17 and the A line and the length between the A line and the B line. The sum of the lengths of the leads 8, the length between line A and line B, and the length between line C and line D. The difference lies in the different lengths of the leads 8 between line A and line B, and between line C and line D. It is only necessary to design the sum of the length differences of the leads 8 between line A and line B, and between line C and line D to be equal to the length difference between the leads 8, so as to achieve the purpose of accurately controlling the length of each lead 8 without measurement. This mechanical design is very easy to implement through existing technology. For example, in this embodiment, each lead 8 forms a right triangle between line A and line B, and between line C and line D. It is easy to calculate the length of each side and use it as the basis for mechanical design. The bending position of the lead 8 can also be more accurately calculated according to the corresponding bending radian. The bending radian can be calculated through the relationship between the arc length and the arc radius. These are all conventional applications of existing technology and will not be repeated here.

[0034] The above embodiments are only preferred embodiments of the present invention and are not limitations on the technical solutions of the present invention. Any technical solution that can be implemented on the basis of the above embodiments without creative work should be deemed to fall within the scope of protection of the patent of the present invention.
