Description

Technical Field

[0001] This utility model relates to the field of wire harness production technology, and in particular to a terminal clamping tool. Background Technology

[0002] In existing wire harness production processes, terminal assembly is required manually; for example, the W034060 AC power terminal typically requires manual screw tightening. However, relying on manual screw tightening presents the following problems: 1. High risk of human error: Manual work for extended periods can lead to fatigue, resulting in incomplete tightening or insufficient torque. 2. Low efficiency: Manual assembly is slow and cannot meet the demands of large-scale production. In actual production, there is no suitable and effective tooling to solve these problems. Utility Model Content

[0003] To address the shortcomings in the aforementioned background technology, this utility model proposes a spring-type terminal clamping fixture for electric vehicle charging and distribution units, which solves the problem of low efficiency in manually tightening screws on terminals in the prior art.

[0004] The technical solution of this utility model is implemented as follows: A spring-type terminal clamping fixture for an electric vehicle charging and distribution unit includes a base body with several limiting grooves. A conforming clamping block assembly for clamping terminals is provided in the limiting grooves. The conforming clamping block assembly is correspondingly arranged with a spring assembly in the limiting groove. The spring assembly provides a clamping force for clamping the terminals to the conforming clamping block assembly. The spring assembly and the conforming clamping block assembly are limited in the limiting grooves by an upper cover plate. The upper cover plate is provided with an insertion groove corresponding to the conforming clamping block assembly. The upper cover plate is detachably connected to the base body.

[0005] Further preferably, the base includes a left base and a right base arranged opposite to each other; both the left and right bases are provided with a plurality of U-shaped grooves along their length, and the U-shaped grooves on the left base and the U-shaped grooves on the right base correspond to form limiting grooves. The separate base design facilitates disassembly and maintenance, and also reduces mold production costs.

[0006] Further preferably, both the left and right seats are provided with longitudinal bolt holes, and the left and right seats are connected by bolts that are threaded into the longitudinal bolt holes.

[0007] In a further preferred embodiment, the upper cover plate includes a left cover plate and a right cover plate arranged opposite to each other. Both the left cover plate and the right cover plate are provided with side grooves. The side grooves of the left cover plate and the right cover plate form an insertion groove. The left cover plate is fixed to the top of the left seat body by bolts, and the right cover plate is fixed to the right seat body by bolts.

[0008] Further preferably, the contour clamping block assembly includes two opposing movable clamping blocks, each with a semi-circular groove, the two movable clamping blocks forming a cylindrical groove.

[0009] In a further preferred embodiment, the movable clamping block is slidably disposed within the limiting groove, and the height of the movable clamping block is not higher than the depth of the limiting groove; ensuring that it can move smoothly under the action of the limiting groove and the upper cover plate.

[0010] In a further preferred embodiment, the contour clamping block assembly includes a movable clamping block and a fixed clamping block arranged opposite to each other. The fixed clamping block is fixed in the limiting groove by adjusting bolts. Both the movable clamping block and the fixed clamping block are provided with semi-circular slots, and the semi-circular slots of the movable clamping block and the fixed clamping block form a cylindrical slot.

[0011] In a further preferred embodiment, the movable clamping block and the fixed clamping block are set at the same height and their height is not higher than the depth of the limiting groove; ensuring that they can move smoothly under the action of the limiting groove and the upper cover plate.

[0012] In a further preferred embodiment, a spring assembly is provided between the movable clamping block and the seat corresponding to the limiting groove, and the spring assembly is located within the limiting groove; the spring assembly pushes the corresponding movable clamping block to move within the limiting groove to clamp the terminal.

[0013] Further preferably, the spring assembly includes a first positioning post disposed on the back of the movable clamping block and a second positioning post disposed on the longitudinal side wall of the limiting groove, with a clamping spring disposed between the first positioning post and the second positioning post; the first positioning post and the second positioning post ensure that the clamping spring is in a stable state, so as to provide a smooth clamping force for the movable clamping block.

[0014] The beneficial effects of this utility model are as follows: This utility model uses a limiting groove, a contour clamping block assembly, and a spring assembly to stably clamp the terminal. Then, by using an electric wrench to tighten the screw, torque can be guaranteed while rapid assembly is achieved. The contour clamping block assembly, with two semi-circular contour clamping blocks and a spring as the clamping force, ensures even force distribution on the circular terminal, increases friction, and prevents the terminal from rotating, thus ensuring accuracy and stability in high-intensity working environments. Furthermore, this utility model has a high degree of structural integration and a compact design, suitable for placement in confined spaces; its simple and reasonable design facilitates 5S management and meets the needs of large-scale production.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1, such as Figure 1As shown, a spring-type terminal clamping fixture for an electric vehicle charging and distribution unit includes a base 1, preferably a U-shaped structure. The base has mounting holes 7 at both ends, which can be threaded or smooth holes, used to fix the base to an operating table. The base 1 has several limiting grooves 2. The number of limiting grooves can be one or more as needed. One limiting groove corresponds to one contour clamping block assembly, and one contour clamping block assembly corresponds to one terminal. To improve terminal threading efficiency, multiple limiting grooves can be set; in this embodiment, five are used as an example. Each limiting groove 2 is provided with a contour clamping block assembly 3 for clamping the terminal. The terminal is a circular terminal. The contour clamping block assembly 3 is correspondingly arranged with a spring assembly 4 set in the limiting groove 2. The spring assembly 4 provides clamping force to the contour clamping block assembly 3 for clamping the terminal. The spring assembly 4 and the contour clamping block assembly 3 are limited within the limiting groove 2 by an upper cover plate 5. The upper cover plate 5 ensures stable movement of the contour clamping block assembly within the limiting groove. The upper cover plate 5 is provided with an insertion slot 6 corresponding to the contour clamping block assembly 3. The insertion slot ensures that the terminal piece is smoothly inserted into the contour clamping block assembly, serving as a guide. Preferably, in this embodiment, the upper cover plate 5 and the base 1 are detachably connected; this detachable connection facilitates quick assembly and connection, and also facilitates the replacement of the clamping block and spring component 4 in the contour clamping block assembly 3, improving the applicability of the tooling. In actual use, the contour clamping block assembly 3 clamps the round terminal, making it convenient to screw on with an electric wrench, ensuring torque while performing rapid assembly, thus improving the efficiency of screwing. This tooling is made of POM material, effectively preventing scratches on the metal terminals.

[0023] In this embodiment, as a preferred solution, the base 1 adopts a split structure. Specifically, the base 1 includes a left base 101 and a right base 102 arranged opposite to each other. Both the left base 101 and the right base 102 have a plurality of U-shaped grooves 201 along their length. The U-shaped grooves 201 on the left base 101 and the U-shaped grooves 201 on the right base 102 correspond to form limiting grooves 2. The split structure facilitates the quick installation and limiting of the spring assembly 4 and the contour clamping block assembly 3. At the same time, the split design of the base facilitates disassembly and maintenance, and reduces the cost of mold production.

[0024] In this embodiment, both the left seat 101 and the right seat 102 are provided with longitudinal bolt holes 103. The left seat 101 and the right seat 102 are connected by bolts that are threaded into the longitudinal bolt holes 103; that is, the left seat 101 and the right seat 102 are connected by bolts to achieve a stable longitudinal connection between them.

[0025] In this embodiment, the upper cover plate 5 includes a left cover plate 501 and a right cover plate 502 arranged opposite to each other. That is, the cover plates also adopt a split design, corresponding to the left and right seats, improving the flexibility of disassembly and assembly of the device. In this embodiment, both the left cover plate 501 and the right cover plate 502 have side grooves. The side grooves of the left cover plate 501 and the right cover plate 502 form insertion grooves 6. These insertion grooves are vertically aligned with the contour clamping block assembly, ensuring that the terminal parts are smoothly inserted into the contour clamping block assembly, thus providing a guiding function. In this embodiment, the left cover plate 501 is fixed to the top of the left seat 101 with bolts, and the right cover plate 502 is fixed to the right seat 102 with bolts, enabling quick disassembly and assembly.

[0026] Example 2, as Figure 2 As shown, a spring-type terminal clamping fixture for an electric vehicle charging and distribution unit, based on Embodiment 1, includes two opposing movable clamping blocks 301. Each movable clamping block 301 has a semi-circular groove 302, which serves as a contour groove for the circular terminal. The semi-circular grooves 302 of the two movable clamping blocks 301 form a cylindrical groove to accommodate the circular terminal, ensuring stable clamping. In this embodiment, the movable clamping blocks 301 are slidably disposed within a limiting groove 2, and the height of the movable clamping blocks 301 is not greater than the depth of the limiting groove 2; ensuring smooth movement under the action of the limiting groove and the upper cover plate. This embodiment uses two movable clamping blocks that can move relative to or away from each other. Under the action of their spring assembly, the two movable clamping blocks can move synchronously to quickly clamp the circular terminal. The clamping distance between the two contour movable clamping blocks has been rigorously tested to ensure proper clamping.

[0027] Example 3, as Figure 3As shown, a spring-type terminal clamping fixture for an electric vehicle charging and distribution unit differs from Embodiment 2 in that the conformal clamping block assembly 3 in this embodiment includes a movable clamping block 301 and a fixed clamping block 303 arranged opposite to each other. The fixed clamping block 303 is fixed in the limiting groove 2 by an adjusting bolt 304, while the movable clamping block 301 moves relative to the fixed clamping block by a spring assembly. The adjusting bolt 304 passes through the base and is hinged to the back of the fixed clamping block 303. Rotating the adjusting bolt limits the position of the fixed clamping block, thus both fixing the fixed clamping block and adjusting its position in the limiting groove. Both the movable clamping block 301 and the fixed clamping block 303 have semi-circular slots 302, which are conformal slots for circular terminals. The semi-circular slots 302 of the movable clamping block 301 and the fixed clamping block 303 form a cylindrical slot to accommodate the circular terminal and ensure stable clamping of the circular terminal. The movable clamping block 301 and the fixed clamping block 303 are set at the same height, and their height does not exceed the depth of the limiting groove 2; this ensures that they can move smoothly under the action of the limiting groove and the upper cover plate. In this embodiment, a fixed clamping block and a movable clamping block are used in conjunction; the movable clamping block moves relative to the fixed clamping block under the action of its spring assembly to quickly clamp the circular terminal. The clamping distance between the movable clamping block 301 and the fixed clamping block 303 has been rigorously tested to ensure that the circular terminal is clamped in place.

[0028] Example 4, as Figure 4 , 5 As shown, a spring-type terminal clamping fixture for an electric vehicle charging and distribution unit, based on embodiments 1, 2, or 3, includes a spring assembly 4 between the movable clamping block 301 and the corresponding seat 1 of the limiting groove 2. The spring assembly provides clamping power to the movable clamping block, and the spring assembly 4 is located within the limiting groove 2. Specifically, the spring assembly 4 includes a first positioning post 401 disposed on the back of the movable clamping block 301 and a second positioning post 402 disposed on the longitudinal sidewall of the limiting groove 2. A clamping spring 403 is disposed between the first positioning post 401 and the second positioning post 402. The first positioning post 401 and the second positioning post 402 are at the same height, so that the clamping spring is in a straight state, thereby providing a stable pushing force to the movable clamping block.

[0029] In use, the circular terminal is inserted into the conformal clamping block assembly through the insertion slot. The conformal clamping block assembly clamps the bottom of the circular terminal. Then, an electric wrench can be used to tighten the screws, which improves the installation efficiency.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
