Description

Technical Field

[0001] This utility model relates to the field of connector testing technology, specifically a multi-functional assembly clamp for connector assembly and testing machines. Background Technology

[0002] As is well known, in the field of connector assembly and testing, connector assembly and testing machines rely on assembly clamps to fix and position connectors, ensuring assembly accuracy and testing efficiency. However, existing assembly clamps have many shortcomings in practical applications, making it difficult to meet the demands of efficient and stable production. Specific problems are as follows: Existing assembly clamps are mostly fixed to the test machine workbench by bolt drilling. This is not only cumbersome to install and disassemble, requiring tools, but also damages the workbench surface when bolt drilling is used. In addition, this fixing method is only suitable for workbenches made of specific materials (such as metal) and with flat surfaces. It has poor compatibility with workbenches made of easily damaged materials such as plastic and acrylic, or workbenches with small protrusions on the surface, thus limiting its applicable scenarios. Existing assembly clamps are mostly designed with a single clamping position, which can only clamp one connector at a time, failing to meet the needs of batch assembly and testing, resulting in low production efficiency; moreover, the clamping structure is mostly rigid and fixed, with poor adaptability to connectors of different specifications, requiring frequent adjustment or replacement of the clamp body when changing the clamping object, which is cumbersome. During connector assembly and testing, some working scenarios (such as inside equipment or backlit areas of production lines) are poorly lit, and existing assembly clamps are not equipped with auxiliary lighting structures. Operators may misplace connectors due to poor visibility, increasing the assembly error rate and affecting the testing progress and product qualification rate. Therefore, it is necessary to propose solutions to the above technical problems. Utility Model Content

[0003] Technical problems to be solved To address the shortcomings of existing technologies, this utility model provides a multi-functional assembly clamp for a connector assembly and testing machine.

[0004] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a multi-functional assembly clamp for a connector assembly and testing machine, comprising a suction cup and a fixing plate. The top of the suction cup is provided with a sealing post, and a sealing groove is formed between the bottom end of the sealing post and the bottom end of the suction cup. A threaded hole is formed between the top of the sealing post and the sealing groove, and a threaded post is provided in the threaded hole. A sealing plug is provided at the bottom end of the threaded post and is located in the sealing groove. An annular groove is formed at the top of the suction cup, and a threaded ring is provided in the annular groove. Support posts are provided on both sides of the top of the threaded ring, and a support plate is provided between the two support posts. A splicing mechanism is provided between the fixing plate and the support plate. A lighting mechanism and a clamping plate are provided at the top of the fixing plate. Plastic arc rings are provided on both sides of the top of the clamping plate, and multiple clamping plates are provided and arranged in an array.

[0005] Furthermore, the splicing mechanism includes a splicing strip and a splicing groove. The splicing strip is installed at the bottom end of the fixed plate, and the splicing groove is opened at the top end of the support plate and extends through both ends therethrough. The splicing strip passes through the splicing groove, and grooves are provided on both sides of the splicing strip. Elastic protrusions are provided on both sides of the inner wall of the splicing groove. Both the splicing strip and the splicing groove have a T-shaped structure.

[0006] Furthermore, the splicing mechanism has two parts arranged symmetrically.

[0007] Furthermore, a fastening hole is provided on the plastic arc ring on one side of the top of each clamping plate, and a threaded shaft is provided in the fastening hole. The threaded shaft is threadedly connected to the fastening hole, and a fastening block is provided at one end of the threaded shaft.

[0008] Furthermore, a sealing ring is provided at the bottom end of the suction cup.

[0009] Furthermore, the sealing plug and the sealing ring are made of high and low temperature resistant rubber material.

[0010] (III) Beneficial Effects Compared with the prior art, this utility model provides a multi-functional assembly clamp for a connector assembly and testing machine, which has the following advantages: This connector assembly and testing machine uses a multi-functional assembly clamp with a suction cup as the basic fixing structure. It eliminates the need for bolts and drilling to connect to the workbench, avoiding damage to the workbench surface. It is also compatible with workbenches made of different materials such as metal, plastic, and acrylic. With the sealing structure composed of sealing pillars, sealing grooves, sealing plugs, and threaded pillars, rotating the threaded pillars can move the sealing plugs within the sealing grooves, blocking air backflow and enhancing the stability of the negative pressure inside the suction cup. This effectively prevents the assembly clamp from shifting during assembly and testing, improving the reliability of the fixation. By arraying multiple clamping plates on a fixed plate, each equipped with a plastic arc ring at its top, multiple connectors can be simultaneously clamped and fixed. Compared to existing single-clamping assembly clamps, batch clamping efficiency is improved, assembly and testing cycles are significantly shortened, and the needs of large-scale production are met. Furthermore, the plastic arc rings are elastic, allowing for initial wrapping of the sidewalls of connectors of different specifications, eliminating the need for frequent clamp replacements, thus enhancing adaptability and preventing scratches to the connectors caused by rigid contact. An additional lighting mechanism is added to the top of the fixed plate. When ambient light is insufficient during assembly and testing, activating the lighting mechanism illuminates the clamping plate area, providing operators with a clear view and effectively preventing connector misalignment due to poor visibility, ensuring testing accuracy and product yield.

[0013] 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.

[0014] Please see Figures 1-4This utility model is a multi-functional assembly clamp for a connector assembly and testing machine, including a suction cup 1 and a fixing plate 2. The suction cup 1 has a sealing post 3 at its top, and a sealing groove is formed between the bottom end of the sealing post 3 and the bottom end of the suction cup 1. A threaded hole is formed between the top end of the sealing post 3 and the sealing groove, and a threaded post 4 is provided in the threaded hole. A sealing plug 5 is provided at the bottom end of the threaded post 4 and is located in the sealing groove. The suction cup 1 has an annular groove, and a threaded ring 6 is provided in the annular groove. Support posts 7 are provided on both sides of the top end of the threaded ring 6, and a support plate 8 is provided between the two support posts 7. A splicing mechanism is provided between the fixing plate 2 and the support plate 8. The top of plate 2 is equipped with a lighting mechanism 9 and a clamping plate 10. The clamping plate 10 has plastic arc rings 11 on both sides of its top. Multiple clamping plates 10 are arranged in an array. In this embodiment, the bottom of the suction cup 1 is placed against the worktable of the connector assembly testing machine (ensuring the worktable is flat). The suction cup 1 is pressed to expel internal air, using atmospheric pressure to achieve initial adsorption. To enhance adsorption stability, the threaded post 4 is rotated (the threaded hole and threaded post 4 are threadedly engaged), causing the sealing plug 5 at the bottom of the threaded post 4 to move upwards within the sealing groove. This creates a pressure difference between the air inside the suction cup 1 and the outside air. Simultaneously, the sealing plug 5 is tightly fitted against the inner wall of the sealing groove, preventing air backflow and further enhancing the sealing adsorption force of the suction cup 1. The fixing plate 2 is assembled onto the support plate 8 via a splicing mechanism. If the ambient light during assembly testing is insufficient, the lighting mechanism 9 (such as an LED light group) at the top of the fixing plate 2 is activated to illuminate the area of ​​the clamping plate 10, preventing connector misalignment due to poor visibility. Place the connector between the two plastic arc rings 11 at the top of the clamping plate 10 (the plastic arc rings 11 have a certain degree of elasticity, initially wrapping the sidewalls of the connector to avoid scratches from hard contact); repeat the operation to achieve synchronous clamping and fixing of multiple connectors. The suction cup 1 adsorption eliminates the need for bolts and drilling, adapts to workbenches of different materials, and the sealed structure improves adsorption stability and prevents device displacement. The array of multiple clamping plates 10 can simultaneously clamp multiple connectors, and the lighting mechanism 9 solves the problem of operation in low light and reduces the error rate of assembly and testing. In this solution, the splicing mechanism includes a splicing strip 12 and a splicing groove. The splicing strip 12 is installed at the bottom of the fixed plate 2, and the splicing groove is opened at the top of the support plate 8 and extends through both ends of it. The splicing strip 12 passes through the splicing groove, and grooves are provided on both sides of the splicing strip 12. Elastic protrusions 13 are provided on both sides of the inner wall of the splicing groove. Both the splicing strip 12 and the splicing groove have a T-shaped structure. There are two splicing mechanisms, which are symmetrically arranged. The T-shaped splicing strip 12 and the splicing groove are matched with each other. The T-shaped structure prevents the upper and lower parts from separating. The groove of the splicing strip 12 and the elastic protrusion 13 of the splicing groove are elastically engaged. The elastic protrusion 13 can be deformed under external force, which is convenient for disassembly and assembly. When there is no external force, it remains engaged, realizing a detachable and stable connection between the fixed plate 2 and the support plate 8. The T-shaped structure prevents the fixed plate 2 from wobbling up and down, while the elastic protrusions 13 prevent lateral displacement, ensuring no looseness after splicing. No tools are required; splicing and disassembly can be completed simply by pushing and pulling the fixed plate 2, saving assembly and disassembly time. The two symmetrically arranged splicing mechanisms ensure that the bottom of the fixed plate 2 is evenly stressed (symmetrically distributed left and right), avoiding tilting or concentrated stress on the fixed plate 2 caused by a single splicing mechanism (unilateral stress can easily cause deformation at the splice). In this design, a fastening hole is provided on the plastic arc ring 11 on one side of the top of each clamping plate 10. A threaded shaft 14 is provided in the fastening hole, and the threaded shaft 14 is threadedly connected to the fastening hole. A fastening block 15 is provided at one end of the threaded shaft 14. The threaded drive between the threaded shaft 14 and the fastening hole (rotating the threaded shaft 14 can achieve axial movement) drives the fastening block 15 to advance linearly. By adjusting the screw depth of the threaded shaft 14, the clamping force of the fastening block 15 on the connector can be controlled. The fastening block 15 is in direct contact with the connector, and the clamping force can be adjusted for connectors of different thicknesses and diameters to avoid the plastic arc ring 11 being too loose and shifting or too tight and scratching when clamped alone.

[0015] In this solution, the bottom end of the suction cup 1 is provided with a sealing ring 16. When the sealing ring 16 at the bottom end of the suction cup 1 comes into contact with the work surface, it deforms to fill the tiny gap between the suction cup 1 and the work surface, blocking air from flowing back from the edge of the suction cup 1 and enhancing the sealing performance inside the suction cup 1.

[0016] In this solution, the sealing plug 5 and the sealing ring 16 are made of high and low temperature resistant rubber material. The high and low temperature resistant rubber material has temperature stability. Under high and low temperature environments (such as high temperature aging test of connector, low temperature performance test), it will not cause sealing failure due to high temperature softening, nor will it lose its deformation ability due to low temperature hardening. It always maintains a tight fit with the contact parts (sealing plug 5 and sealing groove, sealing ring 16 and platform).

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
