Description

Technical Field

[0001] This utility model relates to the field of wire harness connector assembly equipment technology, and in particular to an auxiliary tooling for wire harness connector assembly. Background Technology

[0002] Wire harness connectors are widely used components in electronic equipment, automobiles, and other fields. They serve as bridges for transmitting signals and connecting current in electronic devices. Wire harnesses typically consist of an insulating sheath, terminals, wires, and insulating wrapping material. The terminals are the wire harness connectors, which enable connections between the wire harness and external devices or other wire harnesses, providing a pluggable connection method for signal and power transmission. As a crucial component of electronic products, the assembly process involves first stripping the wires from the wire harness, then crimping them into the terminals, and finally inserting the terminals along with the wire harness into the terminal housing.

[0003] After stripping the wire harness, it needs to be inserted and mated with the terminals one by one. However, due to the large number of wire harnesses connected to the connector, manual insertion is difficult and inefficient, and it's impossible to guarantee consistent insertion depth. Furthermore, the clamping and deformation of the terminals is difficult to adjust manually, compromising the sufficiency and effectiveness of the clamping. While existing automated assembly equipment can efficiently and continuously perform batch assembly, it is typically bulky and only suitable for production line processing. When assembling wire harness terminals during actual product connection, usually involving a single or several connectors, conventional automated assembly equipment is unusable. Manual assembly is usually required, pushing individual wire harnesses into the terminals one by one. However, variations in the insertion depth of different wire harnesses can easily lead to misalignment between the wire harness and the terminal, resulting in incomplete disengagement and connection failure, thus affecting the quality of the wire harness connector assembly. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary tooling for assembling wire harness connectors that can adjust the extension length of several parallel wire harnesses to ensure the consistency and sufficiency of the insertion length, while clamping several terminals to ensure the stability and effectiveness of wire harness clamping. This solves the problem that existing automated wire harness assembly equipment cannot assemble individual wire harness connectors in the operating environment due to size limitations. Although existing manual assembly methods alleviate the limitation of assembly space, manual operation can only assemble a single wire harness. The total assembly time for multiple wire harnesses is long, and the insertion depth and sufficiency of the wire harness cannot be effectively guaranteed. Furthermore, the degree of clamping deformation of the terminals cannot be kept consistent, which easily leads to unstable clamping. This results in poor assembly quality and low assembly efficiency for wire harness connectors.

[0036] Preferably, the terminal positioning assembly 4 includes a positioning platform 41, a plug-in support column 42, a pressure plate 43, a sealing block 44, and a limiting spring 45. Preferably, the positioning platform 41 is mounted on the base 11. More preferably, the top surface of the positioning platform 41 supports the plug-in support column 42. Preferably, the pressure plate 43 is fitted onto the plug-in support column 42. Preferably, a limiting spring 45, which can limit the working position of the pressure plate 43, is fitted onto the column of the plug-in support column 42 above the pressure plate 43. Preferably, a sealing block 44, which can limit the position of the limiting spring 45 on the plug-in support column 42, is also connected to the axial upper end of the plug-in support column 42. The positioning platform 41 provided in this application can cooperate with the pressure plate 43, which is limited by the limiting spring 45, to clamp and position the terminal, so as to ensure the positional stability of the terminals connected by multiple connecting pieces, effectively limit the relative position between the terminal and the wire harness, and keep the terminal and the stripped wire of the wire harness coaxial, so as to accurately fit the terminal onto the wire harness.

Preferably, the end of the threaded adjusting rod 414 is rotatably connected to the side surface of the platform body 412 away from the guide separating and gathering assembly 3 through a rotating shaft bearing. Preferably, a receiving half-groove 415 for placing terminals is provided at intervals on the top surface of the platform body 412. Preferably, a mounting groove for accommodating the pressing mechanism 6 is also provided on the platform body 412, and longitudinal rail grooves are also provided on the two longitudinal side walls of the mounting groove.

[0038] Preferably, the dual-position cutting assembly 5 includes a movable square rod 51 movably passing through the mounting plate 13, a return spring 52 sleeved on the movable square rod 51, a sleeved baffle 53 defining the position of the return spring 52, and a double-edged blade assembly 54 connected to the axial lower end of the movable square rod 51. More preferably, the sleeved baffle 53 is sleeved on the rod body of the movable square rod 51 above the mounting plate 13. Preferably, the connecting base plate 541 of the double-edged blade assembly 54 is connected to the axial lower end face of the movable square rod 51 below the mounting plate 13 in a manner parallel to the mounting plate 13. Preferably, two vertical blades 542 are arranged in parallel on the bottom surface of the connecting base plate 541. The movable square rod 51 provided in this application can drive the two vertical blades 542 to descend by abutting the side edges of the guide separating and gathering assembly 3 and the terminal positioning assembly 4 respectively when pressed down, thereby cutting off the front end of the wire harness and the terminal connecting piece. Specifically, when the double-position cutting assembly 5 is not subjected to external pressure, it is limited by the elastic potential energy of the return spring 52, and the height of the two vertical blades 542 is higher than that of the blocking block 44, thereby facilitating the movement of the table body 412 after the cutting process is completed. This application in Figure 1 The dual-position cutting assembly 5 shown in the diagram is not the initial working position, but a relative position structure diagram when it is subjected to a certain downward pressure and a certain amount of descent. It is used to define the surface. The two vertical blades 542 can perform cutting operations on the two positions under synchronous drive in order to obtain several parallel and spaced wire harnesses and mutually separated terminals.

[0039] Preferably, the pressing mechanism 6 includes a first longitudinal sliding plate 61, a second longitudinal sliding plate 62, a first driving rod 63, a second driving rod 64, a first limiting elastic element 65, a second limiting elastic element 66, and clamping teeth 67. Preferably, the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62 are mounted in the mounting groove of the platform 412 in a manner that allows them to move longitudinally in opposite directions. Preferably, the two opposite sides of the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62 are respectively connected to the first driving rod 63 and the second driving rod 64, which penetrate the side wall of the platform 412. Preferably, the first driving rod 63 and the second driving rod 64, located outside the platform 412, are also respectively fitted with a first limiting elastic element 65 and a second limiting elastic element 66 that can limit the initial working position. Preferably, the ends of the first driving rod 63 and the second driving rod 64 are each provided with a baffle plate. Preferably, the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62 extend to the upper edge of the plate body 412 and are provided with clamping teeth 67 at intervals. When the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62 move towards each other, the clamping teeth 67 on the upper edge of the two plates approach each other and clamp and squeeze the terminal, thereby causing the terminal to deform in section and effectively clamp the wire harness inserted therein. The two parallel first longitudinal sliding plates 61 and the second longitudinal sliding plate 62 provided in this application can move in opposite directions under the drive of the first drive rod 63 and the second drive rod 64, so that the clamping teeth 67, which are arranged at intervals on both sides of the terminal and staggered on the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62, can clamp the terminal in a way that causes partial deformation of the terminal and clamps and fixes the wire harness inside it, so as to achieve the fixed connection and positioning between several terminals and wire harnesses.

[0040] The working principle of this application is as follows:

[0041] During assembly, multiple stripped wire harnesses are first clamped into the wire clamping grooves 21 of the separating positioning plate 2 by pressing them down. The stripped ends are then inserted into the gathering holes formed by the guide separating and gathering assembly 3, so that the uneven ends of the wire harnesses extend outside the gathering holes. The pressure plate 43 is manually pulled to increase the distance between the pressure plate 43 and the positioning table 41, and multiple terminals with terminal connecting pieces are placed into the receiving plate groove 415. Then, the position of the terminals on the positioning table 41 is limited by the pressure plate 43, which is limited by the limiting spring 45. By quickly pressing down the movable square rod 51, the double-edged blade assembly 54 descends along the edges of the guide separating and gathering assembly 3 and the positioning table 41 to quickly cut off the uneven ends of the wire harnesses and the terminal connecting pieces. After the external force of pressing down is released, the double-edged blade assembly 54 moves upward with the movable square rod 51 to above the horizontal plane of the sealing block 44 to avoid obstructing the translation of the terminal positioning assembly 4. Then, by turning the threaded adjusting rod 414, the working position of the platform 412 is changed, causing the terminal to gradually approach the convergence outlet of the convergence hole. The wire harness is driven through the guide and convergence assembly 3 and inserted into the terminal by moving the separating positioning plate 2. The first driving rod 63 and the second driving rod 64 are manually pressed simultaneously, causing the first longitudinal sliding plate 61 and the second longitudinal sliding plate 62 to move in opposite directions. This causes the clamping teeth on both sides of the terminal, which are spaced apart at their upper edges, to come closer together and clamp the terminal, causing the terminal to deform and effectively defining the relative position of the wire harness within the terminal.
