Abstract
Description
Technical Field
[0001] This utility model relates to the field of potting fixture technology, specifically to a modular switch harness anti-offset potting fixture. Background Technology
[0002] During the potting and encapsulation process of switches, the stable positioning of the switch within the tooling cavity is crucial to ensuring potting quality.
[0003] Existing dispensing fixtures are mostly simple cavities that allow for movement after the switch is placed in, making them prone to misalignment during dispensing and affecting product quality and consistency. Furthermore, because the switch has a wiring harness connected to its tail, even slight pulling of the harness during handling or vibration / movement of the dispensing equipment can easily cause the switch to wobble back and forth within the cavity. This results in a significant misalignment between the dispensing head and the preset position, preventing the glue from accurately filling the designated area and causing the switch to tilt after dispensing, leading to glue leakage and quality problems such as poor sealing, degraded electrical performance, and unsightly appearance. Therefore, a dispensing fixture that can actively and reliably lock the switch to fundamentally prevent its wobble is needed. Utility Model Content
[0004] The purpose of this invention is to provide a modular switch harness anti-displacement potting fixture, aiming to solve the aforementioned technical problems existing in the prior art. To achieve the above objectives, the present invention adopts the following technical solution: A modular switch harness anti-offset potting fixture includes a mounting base plate and a switch harness fixedly installed on a working plane. The top of the mounting base plate is arranged in a straight line, and at least two sets of potting modules are detachably installed at equal intervals. The glue-filling module includes a base. The top of the base has a sliding groove and multiple equally spaced glue-filling grooves along its length. One end of each glue-filling groove is connected to the sliding groove. A slide bar is slidably connected inside the sliding groove. A protruding locking block is provided on one side of the slide bar facing the opening of each glue-filling groove. Two clamping components are provided at both ends of the top of the base. The slide bar is fixedly installed in the sliding groove by two sets of clamping components. When the grooves formed by the two locking blocks are aligned with the opening of the glue-filling groove, the switch harness is placed in the space formed by the glue-filling groove and the groove. When the locking blocks are aligned with the opening of the glue-filling groove, the switch harness is confined within the glue-filling groove by the locking blocks.
[0005] In one embodiment of this utility model, mounting blocks are fixedly installed on both the left and right sides of the top surface of the mounting base. The top surface of the mounting blocks near the center of the mounting base has multiple mortises equidistantly spaced along its length. Both ends of the base are provided with tenons that match the shape of the mortises. The base is connected between two mounting blocks by the tenons at both ends corresponding to the mortises. A clamping component is provided on the top surface of the base near the mortises, and the clamping component clamps the tenons into the mortises.
[0006] In one embodiment of this utility model, the first clamping component and the second clamping component have the same structure, both including a pressure plate and a bolt assembly. The pressure plate is fastened to the base or the top surface of the assembly pillow block by the bolt assembly.
[0007] In one embodiment of this utility model, a plurality of plug holes are evenly provided on the side of the sliding groove facing the opening of the glue-filling groove, and rubber plugs are inserted into the plug holes. The sliding strip is pressed tightly against the inner wall of the glue-filling groove by the rubber plugs.
[0008] In one embodiment of this utility model, at least two pads are uniformly arranged between the top surface of the mounting base and the base along the length direction of the base.
[0009] The beneficial effects of this utility model are: Firstly, the modular mortise and tenon connection structure allows for rapid increase or decrease in the number of glue-filling modules, flexibly adapting to different production demands and improving production adaptability. Secondly, the precise positioning of the wire harness is achieved through the cooperation of the slider and the locking block. Combined with the elastic buffer of the rubber stopper, the wire harness is fundamentally prevented from shifting or shaking during glue dispensing, which significantly improves the glue dispensing accuracy and product yield. Third, the clamping components and mortise and tenon structure enhance the overall stability of the tooling, and the pad effectively avoids assembly interference, making assembly convenient and efficient. Fourth, the overall structure is simple and compact, with low production costs and excellent sealing performance, which can prevent the product from freezing and failing due to water ingress, further enhancing the reliability of the product and balancing production efficiency and product quality.

Detailed Implementation
[0012] To more clearly illustrate the technical solutions in the embodiments of this utility model or the prior art, the present utility model will be briefly introduced below in conjunction with the accompanying drawings and descriptions of the embodiments or the prior art. Obviously, the following description of the structure of the accompanying drawings is only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. It should be noted that the description of these embodiments is used to help understand this utility model, but does not constitute a limitation on this utility model.
[0013] Example: like Figure 1-5 As shown, this embodiment provides a modular switch harness anti-offset potting fixture, including a mounting base plate 1 fixedly installed on the working plane and a switch harness. The top of the mounting base plate 1 is arranged in a straight line, and at least two sets of potting modules 5 are detachably installed at equal intervals. The potting module 5 includes a base 52. The top of the base 52 has a sliding groove 521 and a plurality of equally spaced potting grooves 522 along its length. One end of the potting groove 522 is connected to the sliding groove 521. A slide bar 53 is slidably connected in the sliding groove 521. A protruding locking block 531 is provided on one side of the slide bar 53 facing the opening of each potting groove 522. Both ends of the top of the base 52 are provided with clamping components 54. The slide bar 53 is fixedly installed in the sliding groove 521 by two sets of clamping components 54. When the grooves formed by the two locking blocks 531 are aligned with the opening of the glue-filling groove 522, the switch harness is placed in the space formed by the glue-filling groove 522 and the groove. When the locking blocks 531 are aligned with the opening of the glue-filling groove 522, the switch harness is confined within the glue-filling groove 522 by the locking blocks 531.
[0014] In one embodiment of this utility model, the structures of the first pressing component 4 and the second pressing component 54 are completely identical, both including a pressure plate 42 and a bolt assembly 41. The pressure plate 42 is fastened to the base 52 or the top surface of the mounting block 3 by the bolt assembly 41.
[0015] Specifically, such as Figure 1-4As shown, this potting fixture adopts a modular splicing structure. Multiple potting modules 5 are fixedly installed on the top surface of the mounting base plate 1 and can be detached. Each potting groove 522 on the top surface of the base 52 is connected by a sliding groove 521. A toothed structure with multiple protruding locking blocks 531 on the surface of the sliding groove 521 is slidably connected to the sliding groove 521 to achieve the switching between two working conditions: pre-installation of switch wiring harness and clamping positioning. When the slide bar 53 slides, the groove between the two locking blocks 531 is aligned with the opening of the potting groove 522, thereby expanding the volume of the potting groove 522 to facilitate the insertion and removal of the switch. When the slide bar 53 slides, the locking block 531 is aligned with the opening of the potting groove 522, the volume of the potting groove 522 is reduced, and the switch is reliably fixed by the side of the locking block 531.
[0016] Meanwhile, the clamping component 54 set on the base 52 clamps the slide bar 53 into the sliding groove 521 through the pressure plate 42 and the bolt assembly 41, achieving reliable mechanical locking, effectively preventing the switch from shaking and shifting due to wire harness pulling during the glue dispensing process, and significantly improving glue dispensing accuracy and product yield. In summary, the tooling is precisely positioned, effectively preventing switch misalignment. Furthermore, by using the sliding slider 53 and the locking block 531 to directly press against the side of the switch, a surface-contact mechanical limit is formed, fundamentally eliminating the possibility of the switch moving back and forth during the glue-pouring process and ensuring the accuracy of the glue-pouring position.
[0017] In one embodiment of the present invention, the sliding groove 521 is further provided with a plurality of plug holes 523 that communicate with it on the side opposite to the opening of the glue-filling groove 522. A rubber plug is inserted into the plug hole 523, and the slide bar 53 is pressed tightly against the inner wall of the glue-filling groove 522 by the rubber plug.
[0018] Specifically, such as Figure 3 As shown, in order to further enhance the locking stability of the slider 53 to the switch, a rubber plug mounting hole is provided on the side of the base 52 facing the glue potting groove 522, and a soft rubber plug is inserted into the hole to provide elastic support for the slider 53. When the slider 53 is in the locked position, its back is pressed against the rubber plug to form a buffer effect and prevent loosening.
[0019] In one embodiment of this utility model, further, mounting blocks 3 are fixedly installed on both the left and right sides of the top surface of the mounting base plate 1. Multiple mortises 31 are equidistantly provided on the side of the top surface of the mounting block 3 near the center of the mounting base plate 1 along its length direction. Both ends of the base 52 are provided with tenons 51 that match the shape of the mortises 31. The base 52 is connected between the two mounting blocks 3 by the tenons 51 at both ends corresponding to the mortises 31. A clamping component 4 is provided on the top surface of the base 52 near the mortises 31, and the clamping component 4 clamps the tenons 51 into the mortises 31.
[0020] Specific examples Figure 5 As shown, by matching tenons 51 and mortises 31 to the base 52 and the mounting block 3 respectively, the glue-filling module 5 and the mounting base plate 1 form a mortise and tenon connection structure for quick positioning and assembly. This allows for the reasonable configuration of the number of glue-filling modules 5 according to actual production needs, enabling them to be used immediately after installation. This quickly adapts to the production structure and improves work efficiency. At the same time, by setting a clamping component 4 on the mounting block 3 to clamp the tenons 51, the glue-filling module 5 is more firmly and stably connected to the mounting base plate 1.
[0021] In one embodiment of this utility model, at least two pads 2 are evenly arranged between the top surface of the mounting base 1 and the base 52 along the length direction of the base 52. By raising the base 52, a suitable assembly gap is left to prevent assembly interference from occurring in this tooling, and the structure of this tooling is further optimized.
[0022] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
