Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic device connector technology, and in particular to the fixing piece of a connector for electronic devices. Background Technology
[0002] During signal or current transmission in electronic devices, the stability and assembly efficiency of connectors directly affect the overall performance of the device.
[0003] Currently, there is an invention patent (European Patent No.: US6053767) filed by a German connector company, which discloses a connector retaining plate with a ring-shaped closed structure (such as...). Figure 1 As shown in the figure, although the structure can achieve the fixing function, it has the following shortcomings: the manufacturing process of the ring-shaped closed structure is complicated, and it is necessary to completely wrap the connector end, resulting in a large amount of material consumption and high production cost; at the same time, the closed design requires precise alignment along the axial direction during assembly, which is difficult to operate and affects production efficiency.
[0004] To overcome the limitations of the existing technology mentioned above, and to optimize the structure and performance of the connector, this utility model proposes a non-closed fixing plate structure. Utility Model Content
[0005] This utility model addresses the shortcomings of existing technologies by providing a fixing piece for connectors in electronic devices. The fixing piece body is adapted to the end of the connector body and has an open, non-closed structure. The bottom of the fixing piece body has a limiting groove for wrapping and limiting the periphery of the connector body end. The bottom sides of the limiting groove each have inwardly extending engaging portions. When the fixing piece body and the connector body end are connected, the inner wall of the limiting groove engages with the periphery of the connector body end to form a peripheral limiting, and the engaging portions are correspondingly inserted into the mating grooves on both sides of the connector body end to form a lateral limiting.
[0006] Preferably, the bottom sides of the limiting groove are provided with support blocks on the outer side of the engaging portion. The support blocks protrude upward perpendicular to the bottom plane of the fixing plate body. When the fixing plate body is connected to the end of the connector body, the top surface of the support block contacts the bottom surface of the end of the connector body to support the end of the connector body and prevent the fixing plate body and the connector body from undergoing relative displacement in the axial direction.
[0007] Preferably, the connector body has a protrusion structure at the middle position of its end that is adapted to the limiting groove. When the fixing plate body is connected to the end of the connector body, the protrusion structure is embedded in the limiting groove to further enhance the radial limiting effect between the fixing plate body and the connector body.
[0008] Preferably, the top surface of the support block is provided with an anti-slip structure, which includes, but is not limited to, fine horizontal stripes, dotted protrusions, or grid patterns, to increase the friction with the bottom surface of the connector body end, thereby improving axial stability.
[0009] Preferably, the end of the engaging portion is provided with a guide structure, which includes, but is not limited to, rounded, chamfered, or tapered guide portions, to reduce the resistance of the engaging portion when inserting into the mating groove during assembly, so as to facilitate quick and accurate assembly.
[0010] Preferably, an elastic buffer layer for increasing connection stability is further provided between the fixing plate body and the connector body. The elastic buffer layer is made of materials such as rubber, silicone or elastic foam. The elastic buffer layer is disposed between the inner side wall of the limiting groove and the outer peripheral wall of the end of the connector body, and / or on the contact surface between the engaging part and the mating groove.
[0011] Preferably, the fixing plate body is made of a material with both elasticity and rigidity, including but not limited to high-strength brass alloy or reinforced nylon plastic, to adapt to deformation requirements during assembly and maintain the fixing effect.
[0012] The beneficial effects of this utility model are:
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. Simplified structure: The U-shaped non-closed structure replaces the traditional ring structure, which simplifies the processing technology, reduces material consumption, and lowers production costs.
[0015] 2. Multi-dimensional limiting and excellent stability: Through the synergistic effect of the limiting groove (peripheral radial limiting), the engaging part and the mating groove (lateral limiting), the support block (axial support), and the concave-convex fit of the protruding structure and the limiting groove (enhanced radial limiting), a multi-dimensional stable connection between the fixing plate and the connector body is achieved, meeting the requirements of electronic equipment for signal / current transmission stability.
[0016] 3. Highly efficient assembly and highly adaptable: The guiding structure reduces assembly resistance, while the anti-slip structure and elastic buffer layer enhance post-assembly stability, making it suitable for automated production lines and significantly improving production efficiency. At the same time, the non-closed design offers greater compatibility with the dimensional tolerances of the connector body, reducing assembly scrap rates.
[0017] 4. Flexible application scenarios and outstanding competitiveness: Flexible material selection can be adapted to different transmission scenarios (signal or current), and the overall structure is lightweight, which helps to reduce the internal space occupied by electronic devices and enhance the overall competitiveness of the product.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.
[0024] Example
[0025] Please refer to Figures 2-4 The fixing plate of the connector for electronic devices includes a fixing plate body 1 that is adapted to the end of the connector body 2; the fixing plate body 1 is a non-closed structure with an opening (in the shape of a U), and its bottom is provided with a limiting groove 10 for wrapping and limiting the periphery of the end of the connector body 2; the bottom sides of the limiting groove 10 are respectively provided with inwardly extending engaging portions 11.
[0026] When the fixing plate body 1 and the connector body 2 are connected, the inner wall of the limiting groove 10 fits tightly with the outer periphery of the connector body 2 to form a radial limiting; at the same time, the engaging part 11 is inserted into the mating groove 20 provided on both sides of the connector body 2 to form a lateral limiting, preventing the fixing plate and the connector body from undergoing lateral relative displacement.
[0027] In an optional embodiment of this application, support blocks 12 are provided on both sides of the bottom of the limiting groove 10 and on the outer side of the engaging part 11. The support blocks 12 protrude upward perpendicular to the bottom plane of the fixing plate body 1. When the fixing plate body 1 is connected to the end of the connector body 2, the top surface of the support block 12 is in close contact with the bottom surface of the end of the connector body 2 to form axial support, effectively preventing relative displacement between the two in the axial direction.
[0028] In an optional embodiment of this application, a protrusion structure 21 adapted to the limiting groove 10 is provided at the middle position of the end of the connector body 2; when the fixing plate body 1 is connected to the connector body 2, the protrusion structure 21 is embedded in the limiting groove 10 and forms a concave-convex fit with the inner sidewall of the limiting groove 10, further enhancing the radial limiting effect of the two and avoiding radial shaking.
[0029] In an optional embodiment of this application, the top surface of the support block 12 is provided with an anti-slip structure (such as fine horizontal stripes, dotted protrusions, or grid patterns), which further improves axial stability by increasing the friction with the bottom surface of the connector body 2, and is especially suitable for electronic devices in vibration environments.
[0030] In an optional embodiment of this application, the end of the engaging part 11 is provided with a guide structure 111 (such as a rounded corner, chamfer, or tapered guide); during the assembly process, the guide structure 111 can reduce the resistance of the engaging part 11 when it is inserted into the mating groove 20, so as to facilitate quick and accurate alignment assembly and reduce assembly time.
[0031] In an optional embodiment of this application, an elastic buffer layer (not shown) (made of materials such as rubber, silicone or elastic foam) is provided between the fixing plate body 1 and the connector body 2. It is disposed between the inner side wall of the limiting groove 10 and the outer peripheral wall of the end of the connector body 2, and / or on the contact surface between the engaging part 11 and the mating groove 20. The elastic buffer layer can absorb assembly errors and vibration impacts, and improve the tightness and stability of the connection.
[0032] In one optional embodiment of this application, the fixing plate body 1 is made of a material with both elasticity and rigidity, including but not limited to high-strength brass alloy (with excellent conductivity, suitable for current transmission scenarios) or reinforced nylon plastic (lightweight, suitable for signal transmission scenarios), which can be flexibly selected according to the application scenario, taking into account both performance and cost.
[0033] like Figure 2-4 As shown, the fixing plate of the connector for electronic devices includes a fixing plate body 1 and a connector body 2. The fixing plate body 1 is a U-shaped non-closed structure made of high-strength brass alloy. A limiting groove 10 is opened at the bottom, and the two sides of the limiting groove 10 extend inward to form a locking part 11. The end of the locking part 11 is provided with a chamfer (guide structure 111). Support blocks 12 are integrally formed on both sides of the bottom of the limiting groove 10 and the outer side of the locking part 11. The top surface of the support block 12 is provided with horizontal stripes (anti-slip structure). The two sides of the end of the connector body 2 are provided with mating grooves 20, and a protrusion structure 21 adapted to the limiting groove 10 is provided in the middle position. A silicone elastic buffer layer is pasted between the inner side wall of the limiting groove 10 and the outer peripheral wall of the connector body 2.
[0034] Assembly process and working principle of this application:
[0035] 1. Assembly process: Align the opening of the fixing plate body 1 with the end of the connector body 2, and push the fixing plate body 1 axially; under the guidance of the guide structure 111 (chamfer), the engaging part 11 smoothly inserts into the mating groove 20, and at the same time, the protruding structure 21 of the connector body 2 is embedded in the limiting groove 10, and the top surface of the support block 12 contacts the bottom surface of the end of the connector body 2; at this time, the elastic buffer layer is compressed, filling the gap and generating pre-tightening force.
[0036] 2. Working principle:
[0037] Radial limiting: The inner wall of the limiting groove 10 cooperates with the outer peripheral wall of the connector body 2, and the protruding structure 21 cooperates with the limiting groove 10 to jointly limit the radial relative displacement of the two.
[0038] Lateral limiting: The engagement of the locking part 11 with the mating groove 20 prevents lateral displacement;
[0039] Axial limiting: The supporting effect of the support block 12 and the preload of the elastic buffer layer prevent axial relative sliding;
[0040] Anti-slip and cushioning: The horizontal stripes on the support block 12 increase friction, and the silicone cushioning layer absorbs vibration to ensure connection stability.
[0041] 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 and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
