[0042] Example 1

[0043] like Figures 1-5 As shown, an automotive cable resistor terminal mounting device includes a resistor terminal mounting mechanism, which comprises a working housing 1 on which a plurality of resistor mounting units 2 are mounted. During installation, each resistor mounting unit 2 serves as an installation station, thus achieving integrated installation and improving installation efficiency.

[0044] Specifically, the resistor mounting unit 2 includes a lower resistor tightening structure and a cable guide structure that cooperates with the lower resistor tightening structure. The cable to be installed is guided from below the cable guide structure to the lower resistor tightening structure, and the resistor terminals are tightened onto the cable by the lower resistor tightening structure.

[0045] The specific structure of the lower resistor tightening structure is as follows:

[0046] The top of the working box 1 is provided with a plurality of mounting holes, and bearings 11 are fixedly installed in the mounting holes. The lower resistance screwing structure includes a rotating shaft 21 fixedly installed on the bearing 11. According to the prior art, a motor is fixedly installed in the working box 1 to drive the rotating shaft 21 to rotate (the motor is not shown in the figure, and is the same as the prior art, and the output shaft of the motor is fixedly installed on the rotating shaft 21, such as through a shaft coupling). The top of the rotating shaft 21 is fixedly connected with a clamping die structure for clamping the resistance terminal. The clamping die structure is a die commonly used to install resistance terminals in the prior art, and the specific structure is as follows:

[0047] The clamping die structure includes a limiting seat 22 for limiting the resistance terminal, and clamping slot structures 221 for clamping the resistance terminal are respectively formed in the side walls on both sides of the limiting seat 22. When the resistance terminal is clamped into the die, at this time, the convex ridge structure on the shell of the resistance terminal is clamped into the clamping slot structure 221, so that the resistance terminal rotates synchronously during the rotation of the clamping die structure.

[0048] Embodiment 2

[0049] As shown in Figures 1-5 the structure of embodiment 1, the above-mentioned cable guide structure includes a guide pipe structure 23. The guide pipe structure 23 includes a lower cylindrical portion 231, the top of which is integrally formed with a conical cylindrical portion 232, and the conical cylindrical portion 232 is integrally formed with a tubular portion 233.

[0050] During the working process, the cable to be installed is guided downward through the guide pipe structure 23, and the vertical posture of the cable is maintained through the downward guiding of the guide pipe structure 23, thereby facilitating the alignment between the threaded structures during the screwing of the resistance terminal, and improving the screwing efficiency.

[0051] At the same time, in order to avoid the self-rotation of the cable during the screwing process, which causes the resistance terminal to fail to be completely screwed in, a plurality of locking structures for preventing the self-rotation of the cable are installed on the above-mentioned cable guide structure. Specifically, the locking structures are installed on the lower cylindrical portion 231.

[0052] Specifically, a plurality of mounting slots 2311 (the bottom of the mounting slot 2311 is open) are formed in the side wall of the lower cylindrical portion 231, and the locking structures are respectively installed in the mounting slots 2311. The locking structure includes a locking wheel arm 27 installed in the mounting slot 2311, and the inner end of the locking wheel arm 27 is rotatably connected with an elastic locking wheel 271 located in the lower cylindrical portion 231 (the elastic locking wheel 271 is made of rubber).

[0053] The cable rubs through between the elastic locking wheels 271 (channels are formed between the elastic locking wheels 271, and the size of the channels is slightly smaller than the diameter of the cable), and the elastic locking wheels 271 elastically extrude the cable to prevent the self-rotation of the cable during the screwing of the resistance terminal.

[0054] Meanwhile, the height of the aforementioned elastic locking roller 271 is adjustable. For example, adjusting the height of the elastic locking roller 271 downwards can further improve the degree of compression and positioning of the cable (the lower it is adjusted, the closer it is to the resistor terminal connection part).

[0055] Specifically, vertically arranged adjusting screws 28 are fixedly connected to the mounting slots 2311, and the adjusting screws 28 are slidably connected to the locking wheel arms 27; a pair of nuts positioned at the top and bottom of the locking wheel arms 27 are threaded onto the adjusting screws 28. The height of the locking wheel arms 27 can be adjusted by loosening the nuts.

[0056] Example 3

[0057] like Figures 1-5 As shown, based on the structure of Embodiment 2, the resistor mounting unit 2 further includes a drive structure for driving the material guide tube structure 23 to rise and fall.

[0058] Specifically, the drive structure includes a fixed seat 26 fixedly connected to the tubular part 233; a lifting cylinder is installed on the left side of the fixed seat 26, specifically, the cylinder of the lifting cylinder is fixedly installed on the top of the working machine box 1; the piston rod of the lifting cylinder is fixedly connected to a lifting rod 241, and the lifting rod 241 is fixedly installed on the fixed seat 26 (both ends of the fixed seat 26 are fixedly connected to bosses, and the lifting rod is fixedly connected to the bosses).

[0059] Meanwhile, a spring sliding structure 25 is installed on the other side of the fixed base 26. The spring sliding structure 25 includes a guide slide rod (the guide slide rod is slidably connected to the boss) that is slidably connected to the fixed base 26, and a return spring is sleeved on the guide slide rod. The two ends of the return spring are respectively fixedly connected to the boss and the top of the chassis.

[0060] During operation, the lifting cylinder 24 lifts the guide tube structure 23 to a certain height. Then, the cable is passed through the guide tube structure 23 in the manner described above (at this time, the cable is pressed and tightened). At this time, the lifting cylinder 24 is closed. With the assistance of the return spring, the guide tube structure 23 carries the cable down until the connector on the cable is aligned with the resistor terminal. As the resistor terminal rotates, the resistor terminal is continuously threaded and tightened onto the connector of the cable (during this process, the resistor terminal slides along the slot).

[0061] Subsequently, the lifting cylinder 24 lifts the guide tube structure 23 again until the guide tube structure 23 is raised, then the cable is pulled out from the guide tube structure 23 to complete the installation.

[0062] This method not only offers high installation efficiency but also ensures high precision during installation, effectively avoiding the technical defect of insufficient connection between resistor terminals caused by cable self-rotation during tightening.

[0063] Of course, the above description is not a limitation of the utility model, the utility model is not limited to the above examples, the changes, modifications, additions or replacements made by the person skilled in the art within the essential scope of the utility model should also belong to the protection scope of the utility model.
