Description

Technical Field

[0001] The invention relates to the technical field of disassembly tools, and in particular to a tool for quickly disassembling a socket terminal. Background Art

[0002] At present, most of the wiring harness assembly connectors configured on electric vehicles have jack terminals. In the production of automobile wiring harness assembly connectors, the jack terminals are often misaligned and the connector sheath is damaged. At this time, the jack terminals need to be disassembled and reassembled. If there is no special disassembly tool, the current common disassembly method is to clamp the jack terminal with pliers manually and pull it out. However, when disassembling with pliers, only the outer periphery of the jack terminal is clamped, and there is no corresponding supporting force inside the jack terminal. In this way, the jack terminal is squeezed inward during the disassembly process, which is prone to deformation and damage. The metal connectors (such as rotating springs) used for conductive connections inside the jack terminal will also be deformed and damaged, resulting in the overall scrapping of the jack terminal, which in disguise increases the production cost of the automobile wiring harness. The outer surface of the jack terminal will also be worn, affecting the aesthetics and the tightness of the insertion, and the disassembly efficiency is low. Summary of the invention

[0021] In order to more fully understand the technical content of the present invention, the present invention will be further introduced and illustrated in conjunction with the accompanying drawings and specific embodiments.

[0022] Example

[0023] like Figures 1 to 5 As shown, a tool for quickly disassembling a socket terminal shown in this embodiment includes a fixed handle 1, a pressure handle 2 rotatably arranged on the fixed handle 1, and a jacket 3 protruding from the upper end of the fixed handle 1, the fixed handle 1 includes a vertical portion 11 and a horizontal portion 12 arranged at the top of the vertical portion 11 and forming a 90-degree angle with the vertical portion 11, the horizontal portion 12 is provided with a through hole 121 penetrating from top to bottom, and the lower end of the jacket 3 is movably arranged in the through hole 121 in a detachable manner; the upper end of the pressure handle 2 is placed below the horizontal portion 12, and the pressure handle 2 is placed below the horizontal portion 12. The upper end of the handle 2 is engaged with a clamping pin 4 that cooperates with the jacket 3. The upper end of the clamping pin 4 is placed in the jacket 3 and there is a gap between the jacket 3. The gap is used to insert and accommodate and clamp the socket terminal. When the pressure handle 2 is rotated, it drives the clamping pin to slide up and down in the jacket 3; a return spring 5 is also sleeved on the clamping pin 4, and the return spring 5 is placed between the bottom of the horizontal part 12 and the pressure handle 2; in the above structure, in the initial state, the elastic force of the return spring is used to make the clamping pin slide downward, and there is a certain height between the upper end of the clamping pin and the upper end of the jacket. The difference in degree is so that when using the tool to disassemble the socket terminal, the sleeve is first put on the outer periphery of the socket terminal, and then the pressure handle is pressed down to make the pressure handle close to the fixed plate, thereby lifting the clamping pin upward to make the clamping pin inserted into the socket terminal, and using the clamping pin and the sleeve to clamp and support the wall of the socket terminal from the inside and outside, and the socket terminal is taken out in the clamped state, ensuring that the socket terminal and the metal connectors in the socket terminal are not deformed or damaged during disassembly and removal, and the sleeve and clamping pin can be used to well protect the outer wall of the socket terminal and the metal connectors in the inner hole, avoid wear on the outer surface of the socket terminal, ensure the aesthetics of the socket terminal after disassembly and the tightness during later insertion, so as to meet the conductive performance of the product and increase the service life and performance of the product; after the socket terminal is taken out, release the pressure handle, and the pressure handle returns to its original position under the action of the range spring and drives the clamping pin to slide downward and disengage from the terminal, thereby releasing the clamping state of the socket terminal, and finally the sleeve and the socket terminal can be easily separated to obtain an intact socket terminal.

[0024] Specifically, the pressing handle 2 includes a main body 21 and a clamping portion 22 bent at the upper end of the main body 21, the clamping portion 22 is rotatably connected to the upper end of the vertical portion 11 by a rivet 6, and the clamping portion 22 is arranged below the horizontal portion 12, the main body 21 is located on the side of the vertical portion 11 opposite to the direction in which the horizontal portion 12 extends forward, the front end of the clamping portion 22 extends forward to the other side of the vertical portion 11 and is placed below the through hole 121, which is used to clamp the clamping needle 4, that is, the clamping needle 4 is engaged with the front end of the clamping portion 22, so that the clamping needle and the main body for pressing down are arranged on both sides of the rotating fulcrum (that is, the rivet), so as to achieve the purpose of rotating the pressing handle 2 and then driving the clamping needle 4 to slide up and down in the jacket 3; the reset spring 5 is placed between the bottom of the horizontal portion 12 and the clamping portion 22, so that the pressing handle and the fixing plate are always in an initial state of separation when not in use.

[0025] Specifically, the clamping portion 22 is composed of clamping plates 221 symmetrically arranged at intervals in front and back, and a clamping groove 222 with openings on three sides is formed between the two clamping plates 221. The upper end of the vertical portion 11 is flat and matched with the clamping plates 221. The clamping groove between the two clamping plates is clamped at the flat part of the vertical portion 11 and connected by rivets 6. Through the combination of the clamping groove, while facilitating the rotation of the pressing handle 2, the bottom of the clamping groove cooperates with the vertical portion to limit the stroke of the pressing handle when it returns to its original position under the elastic force of the reset spring, thereby preventing the pressing handle from rotating too much when subjected to force, resulting in the separation of the clamping needle from the clamping sleeve or the separation of the clamping needle from the clamping portion, and there is no need to set an additional stroke limiting structure.

[0026] A bayonet 7 is provided at the front end of the two clamping plates 221 , and a step position 41 matching with the bayonet 7 is provided at the lower end of the clamping needle 4 , so that the lower end of the clamping needle 4 is clamped in the bayonet 7 , and the upper end passes through the clamping groove 222 and extends upward into the jacket 3 .

[0027] A pulley 8 is rotatably provided in the clamping groove 22 between the front ends of the two clamping plates 221 through a rivet 6, and the pulley 8 is provided below the clamping needle 4 and abuts against the clamping needle 4, and the bottom of the clamping needle 4 is a semicircular shape that cooperates with the pulley 8; in the above, by utilizing the sliding cooperation between the pulley and the semicircular structure, when the pressure handle is rotated, the phenomenon of jamming or blocking between the pressure handle and the clamping needle can be prevented, thereby ensuring the reliability of the structure.

[0028] Specifically, the sleeve 3 includes a fixing portion 31 arranged in the through hole 121 and an inserting portion 32 arranged at the upper end of the fixing portion 31. The fixing portion 31 is fixed by a tightening screw 9 arranged on the side of the horizontal portion 12. The clamping pin and the sleeve are assembled in a detachable manner. In this way, according to the size of the socket terminal, while keeping the outer diameter of the fixing portion 31 unchanged, the sleeve and the clamping pin whose size is compatible with the socket terminal can be replaced, thereby improving the application scope of the disassembly tool and assembling is convenient and quick.

[0029] Four notches 321 are provided at the upper end (i.e., the front end) of the plug-in portion 32 at equal intervals, that is, the connecting lines of the four notches 321 intersect to form a cross shape, so that the front end of the plug-in portion 32 is evenly divided into four elastic clips 322, so that the front end of the plug-in portion 32 divided into four pieces will undergo elastic deformation when subjected to force, which facilitates the insertion of the jacket and the socket terminal, and facilitates the subsequent separation of the jacket and the socket terminal.

[0030] Specifically, a handle cover 10 is provided outside the lower end of the vertical portion 11 of the fixed handle 1 and the lower end of the main body 21 of the pressing handle 2. The handle cover 10 is also provided with a plurality of anti-slip convex points 101 for easy handholding.

[0031] The technical solutions provided by the embodiments of the present invention are introduced in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the embodiments of the present invention. The description of the above embodiments is only applicable to help understand the principles of the embodiments of the present invention. At the same time, for those skilled in the art, according to the embodiments of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
