Description

Technical Field

[0001] This application relates to the field of cable positioning fixture technology, and in particular to a fixture for fixing cable positions and positioning heat shrink tubing. Background Technology

[0002] As a crucial channel for high-frequency signal transmission in electronic devices, RF coaxial cable assemblies typically consist of two main parts: RF coaxial connectors and RF coaxial cables. In actual assembly, to meet the interface layout, space constraints, and electromagnetic compatibility requirements of specific devices, multiple independent RF coaxial cables often need to be precisely arranged and integrated according to the design drawings, and finally permanently bundled and fixed using heat-shrink tubing to form a structurally stable and reliable cable harness unit. However, the traditional fixing method commonly used in the industry for manufacturing such multi-cable harnesses currently relies heavily on the operator's personal skills and experience. The specific operation process of this method is as follows: the operator first lays the design drawings flat on the workbench, then uses simple measuring tools such as a tape measure to measure and compare the dimensions on the drawings one by one, manually determining the relative positions of each cable in the cable harness and the preset installation points of the heat-shrink tubing. This traditional manual positioning and fixing method has several inherent and insurmountable drawbacks: 1. Poor positioning accuracy and difficulty in ensuring quality consistency: Due to complete reliance on manual operation, adjusting the position of one cable can easily pull or squeeze other positioned cables, causing them to shift. This mutual interference makes it easy for the final relative position of each cable to deviate significantly from the design drawings, resulting in overall dimensional deviations and directly affecting the assembly quality of the cable harness and the stability of signal transmission performance.

[0003] 2. Cumbersome operation process and low production efficiency: The process of aligning, repeatedly measuring and calibrating each cable is extremely cumbersome and time-consuming. This not only leads to excessively long assembly time for individual wire harness products, severely limiting production efficiency and capacity, but also makes it difficult to meet the needs of mass production.

[0004] 3. Reliance on skilled workers, high costs, and poor replicability: Product quality is closely related to the skill and responsibility of the operators. Significant differences exist between products made by different personnel or even by the same person in different batches, making it impossible to guarantee high consistency in batch production. Furthermore, companies need to invest heavily in personnel training and quality management, resulting in persistently high production costs.

[0005] Therefore, there is an urgent need for a fixture for fixing and positioning heat shrink tubing that can overcome the above-mentioned defects, so as to achieve rapid, accurate, and standardized positioning and fixing of multi-RF coaxial cables, thereby improving production efficiency and product consistency. Utility Model Content

[0006] The purpose of this application is to overcome the above-mentioned technical problems and provide a fixture for fixing and positioning heat shrink tubing, which can achieve rapid, accurate and standardized positioning and fixing of multi-RF coaxial cables, avoid cable displacement during heat shrinking, and thus improve production efficiency and product consistency.

[0007] This application discloses a fixture for fixing and positioning heat shrink tubing, which specifically adopts the following solution: A fixture for fixing and positioning heat shrink tubing includes: a main body; a fixing component disposed on one side of the main body, the fixing component having a fixing groove for accommodating a connector connected to a cable; and a snap-fit ​​component disposed on the same side of the main body opposite to the fixing component for allowing the cable to pass through, wherein the heat shrink tubing is sleeved on the cable, and a braided mesh tube is sleeved on the heat shrink tubing, so as to be clamped and positioned by the snap-fit ​​component, and then uniformly baked by a heating device to shrink and tighten the cable.

[0008] By adopting the above technical solution, the main body provides a stable support structure for the entire fixture; the fixing component is set on the side of the main body and the fixing groove on it can accommodate and fix the connector connected to the cable, which can prevent the connector from shifting during the baking process of the heat shrink tubing and ensure the stability of the connection between the connector and the cable; the snap-fit ​​component is set on the same side of the main body relative to the fixing component, which allows the cable to pass through and can clamp and position the heat shrink tubing and braided mesh tubing sleeved on the cable, so that the heat shrink tubing is fixed to the braided mesh tubing when the heating equipment is evenly baking, so as to accurately shrink and tighten the cable, thereby improving the accuracy of the heat shrink tubing positioning and the cable tightening effect.

[0009] Optionally, the fixing component includes a first fixing member and a second fixing member, both of which are provided with the fixing groove, and the first fixing member and the second fixing member are at different distances from the buckle component.

[0010] By adopting the above technical solution, the fixing component is provided with a first fixing member and a second fixing member, and the distance between the two and the buckle component is different, which can meet the fixing requirements of connectors in different positions. In conjunction with the buckle component, the cable, heat shrink tubing and braided mesh tubing are clamped and positioned, which can more flexibly position the cable and the connected connector. This makes it easier for the heat shrink tubing to be evenly baked by the heating equipment to drive the braided mesh tubing to shrink and tightly bind the cable.

[0011] Optionally, the buckle assembly includes: a buckle seat, an opening / closing component, and a magnetic component. The buckle seat is disposed on the main body, the opening / closing component is flip-connected to one end of the buckle seat, and the magnetic component is disposed at the other end of the buckle seat for adsorbing the opening / closing component to clamp the cable, the heat shrink tubing, and the braided mesh tubing.

[0012] By adopting the above technical solution, the buckle seat is set on the main body, providing an installation base for clamping and positioning the cable and heat shrink tubing; the opening and closing component is flip-connected to one end of the buckle seat, which allows it to be easily opened when threading the cable and putting on the heat shrink tubing, and can be smoothly closed for clamping after threading; the magnetic component is set at the other end of the buckle seat, which uses the adsorption of the opening and closing component to clamp the cable and heat shrink tubing, which can ensure stable and reliable positioning of the cable, heat shrink tubing and braided mesh tubing, and facilitate the subsequent heating equipment to evenly bake the heat shrink tubing, so that the braided mesh tubing shrinks and tightly binds the cable.

[0013] Optionally, the buckle seat has a positioning groove for multiple cables to pass through, and together with the heat shrink tubing and the braided mesh tubing, they form a tightly bundled set of cables.

[0014] By adopting the above technical solution, a positioning groove is opened on the buckle seat, which allows multiple cables to be threaded through it. With the sleeve of heat shrink tubing, multiple cables can be neatly bundled together to form a group of tightly bound cables, which facilitates the unified management and processing of the cables in the future. At the same time, when the heat shrink tubing is baked by the heating equipment, the braided mesh tube can shrink more evenly and tightly bind the cables, improving the fixing effect and stability of the cables.

[0015] Optionally, both the first and second fixing members are provided with a plurality of fixing slots for accommodating connectors for connecting multiple cables.

[0016] By adopting the above technical solution, multiple fixing slots are provided on the first and second fixing members, which can accommodate connectors connected by multiple cables. The connectors of multiple cables can be fixed at the same time, which improves the fixing efficiency and the number of fixings of the cable connectors by the positioning fixture, and facilitates the batch processing of the cables.

[0017] Optionally, two snap-fit ​​components are provided, arranged side by side on the main body, with the positioning grooves on each snap-fit ​​seat aligned, wherein the heat shrink tubing is provided in two parts and clamped by the two snap-fit ​​components respectively.

[0018] By adopting the above technical solution, two buckle components are set up side by side on the main body, which can simultaneously position the two ends of the heat shrink tubing and the braided mesh tubing, thus improving the stability of the heat shrink tubing positioning; the positioning slots on each buckle seat are set up side by side, which can make multiple cables neatly threaded through, ensuring that the cables are arranged in an orderly manner.

[0019] Optionally, the buckle seat has two rows of positioning slots, and the main body is provided with two fixing components to allow the two sets of cables to be positioned and processed.

[0020] By adopting the above technical solution, two rows of positioning slots are opened on the buckle seat, which allow the two sets of cables to be inserted and positioned respectively, which facilitates the orderly management and positioning of the two sets of cables; the main body is provided with two fixing components, which can respectively accommodate and fix the connectors connecting the two sets of cables, making the two sets of cables more stable during the positioning process, improving the efficiency and accuracy of the positioning process, and enabling the positioning processing of the two sets of cables at the same time.

[0021] Optionally, the two fixing grooves on the first and second fixing members are connected through each other.

[0022] By adopting the above technical solution, the two fixing grooves on the first and second fixing members are connected side by side, which can make reasonable use of space and make the structure of the fixing groove more compact.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. The fixing slot of the fixing component is used to accommodate the connector connected to the fixing cable. The snap-fit ​​component clamps and positions the cable with heat shrink tubing and braided mesh sleeve. The heat shrink tubing is evenly baked by the heating equipment to shrink the braided mesh sleeve and tightly bind the cable. This avoids mutual interference when adjusting the cable position during manual positioning, improves positioning accuracy, and ensures product quality consistency. 2. The fixing component includes a first fixing member and a second fixing member, and the distances between the two and the snap-fit ​​component are different. The first fixing member and the second fixing member are provided with multiple fixing slots, which can accommodate connectors for multiple cable connections. In conjunction with the snap-fit ​​component, the cables and heat shrink tubing are positioned, eliminating the need for tedious alignment, measurement and calibration of each cable, simplifying the operation process, improving production efficiency and adapting to the needs of mass production. 3. The snap-fit ​​assembly includes a snap-fit ​​base, an opening and closing component, and a magnetic component. The opening and closing component can be flipped and connected to one end of the snap-fit ​​base. The magnetic component attracts the opening and closing component to hold cables, heat shrink tubing, and braided mesh tubing, making operation convenient. The snap-fit ​​base is provided with a positioning groove, which allows multiple cables to be threaded through and combined with heat shrink tubing and braided mesh tubing to form a tight cable bundle, achieving fast, accurate, and standardized positioning and fixing of multiple radio frequency coaxial cables. 4. Two snap-fit ​​components are set up and placed side by side on the main body. The two ends of the heat shrink tubing are clamped by the two snap-fit ​​components respectively, which further improves the stability and accuracy of positioning, reduces the dependence on the operator's skill and sense of responsibility, reduces the resource investment in personnel training and quality management, and reduces production costs.

Detailed Implementation

[0026] The terminology used in the following embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. As used in the specification and appended claims of this application, the singular expressions “a,” “an,” “the,” “the,” and “this” are intended to include the plural expressions as well, unless the context clearly indicates otherwise. It should also be understood that the term “and / or” as used in this application refers to and includes any or all possible combinations of one or more of the listed items.

[0027] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as implying or suggesting relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature, and in the description of the embodiments of this application, unless otherwise stated, "multiple" means two or more.

[0028] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0029] See Figure 1 and Figure 2This application discloses a fixture for fixing and positioning heat shrink tubing, comprising a main body 10, a fixing component 20, and a snap-fit ​​component 30. The fixing component 20 and the snap-fit ​​component 30 are disposed opposite each other on the same side of the main body 10. The fixing component 20 is used to fix the connector 50 on the cable 40 and determine the position of one end of the cable 40. The snap-fit ​​component 30 is used to clamp and position the cable 40, which is fitted with heat shrink tubing 60 and braided mesh tubing 70, ensuring accurate arrangement of the cable 40 and accurate positioning of the heat shrink tubing 60 and braided mesh tubing 70. This achieves the effect of rapid, accurate, and standardized positioning and fixing of multi-RF coaxial cables.

[0030] Specifically, the fixing component 20 includes a first fixing member 21 and a second fixing member 22. The first fixing member 21 is made of high-strength plastic material, and its structural strength and fixing effect on the connector 50 are sufficient. It is rectangular block in shape, and its surface is finely polished to avoid scratching the cable 40 and connector 50. The first fixing member 21 has multiple fixing slots 201. The shape of these fixing slots 201 is adapted to the shape of the connector 50 to which the cable 40 is connected. For example, for a square connector 50, the fixing slot 201 is a square groove; for a round connector 50, the fixing slot 201 is a round groove.

[0031] See also Figure 3 The second fixing member 22 has a similar structure to the first fixing member 21, and also has multiple fixing slots 201 for accommodating the connector 50 of the cable 40. The fixing slots 201 on the first fixing member 21 and the second fixing member 22 can be connected through each other, which saves space and facilitates the arrangement and organization of the cable 40. The distances of the first fixing member 21 and the second fixing member 22 from the snap-fit ​​assembly 30 are different to accommodate cables 40 of different lengths or with different arrangement requirements. When the cable 40 connector 50 is placed in the fixing slot 201, the inner wall of the fixing slot 201 fits tightly against the connector 50 to fix the connector 50, thereby determining the position of one end of the cable 40.

[0032] For details, see Figure 2 and Figure 4The snap-fit ​​assembly 30 includes a snap-fit ​​base 31, an opening / closing component 32, and a magnetic component 33. The snap-fit ​​base 31 is made of metal, possessing a certain degree of elasticity and toughness. It is elongated and mounted on the main body 10. The snap-fit ​​base 31 has positioning grooves 311. The number and size of the positioning grooves 311 can be determined according to the actual number and thickness of the cables 40 to be threaded through. For example, when multiple thinner cables 40 need to be positioned, the positioning grooves 311 can be narrower and more numerous; when the cables 40 are thicker, the positioning grooves 311 become wider accordingly. The function of the positioning grooves 311 is to allow multiple cables 40 to be threaded through, and to cooperate with the heat-shrink tubing 60 to fix the braided mesh tube 70, thus encasing multiple cables 40 to form a tightly bundled cable 40.

[0033] The opening / closing component 32 is also made of metal and is flip-connected to one end of the latching seat 31. This connection method can use a hinge connection, making it easy to flip the opening / closing component 32. The magnetic component 33 is embedded at the other end of the latching seat 31 and is used to attract the opening / closing component 32 to hold the cable 40, heat shrink tubing 60, and braided mesh tubing 70. After the cable 40 is inserted into the positioning groove 311 and the heat shrink tubing 60 and braided mesh tubing 70 are successively put on, the opening / closing component 32 is flipped to the position of the magnetic component 33. The magnetic force generated by the magnetic component 33 tightly attracts the opening / closing component 32, thereby achieving the clamping and positioning of the cable 40, heat shrink tubing 60, and braided mesh tubing 70.

[0034] Further, see Figure 2 and Figure 4 Two buckle components 30 are set and arranged side by side on the main body 10. The positioning grooves 311 on each buckle seat 31 are aligned. Two heat shrink tubes 60 are set and clamped by the two buckle components 30 respectively. At the same time, one braided mesh tube 70 is set and its two ends are clamped by the two buckle components 30 respectively.

[0035] Two corresponding clip seats 31 are mounted side-by-side on the main body 10, with their positioning grooves 311 aligned to better position the two ends of the heat shrink tubing 60 and the braided mesh tubing 70. After the cable 40 is inserted into the positioning grooves 311 of the two clip seats 31 and the heat shrink tubing 60 and braided mesh tubing 70 are fitted on, the opening and closing parts 32 of the two clip assemblies 30 are flipped to the magnetic suction parts 33. The magnetic suction parts 33 then attract the opening and closing parts 32, simultaneously clamping and positioning the two ends of the heat shrink tubing 60 and the braided mesh tubing 70. This arrangement further improves the positioning accuracy of the heat shrink tubing 60 and the braided mesh tubing 70, allowing the heat shrink tubing 60 to better fix the braided mesh tubing 70 during the heating and shrinking process, thus more evenly tightening the cable 40.

[0036] For details, see Figure 4The buckle seat 31 has two rows of positioning grooves 311, and the main body 10 has two corresponding fixing components 20 for positioning the two sets of cables 40. The buckle seat 31 has two rows of positioning grooves 311, and the arrangement of each row of positioning grooves 311 is the same as that of the previously described positioning grooves 311. The two fixing components 20 correspond to the two rows of positioning grooves 311, and each fixing component 20 also includes a first fixing member 21 and a second fixing member 22, and both have fixing grooves 201 for accommodating the cable 40 connector 50.

[0037] See also Figure 2 When positioning the cables 40, the two sets of cables 40 are respectively inserted into the two rows of positioning slots 311, and their respective connectors 50 are placed in the fixing slots 201 of the corresponding fixing components 20. Then, the cables 40, heat shrink tubing 60, and braided mesh tubing 70 are clamped and positioned by the opening and closing parts 32 and magnetic suction parts 33 of the snap-fit ​​components 30. This setup allows the fixture to simultaneously position and process two sets of cables 40, greatly improving production efficiency and making it suitable for mass production needs.

[0038] The implementation principle of this embodiment is as follows: the fixing component 20 fixes the connector 50 of the cable 40, ensuring the accurate position of one end of the cable 40; the snap-fit ​​component 30 clamps and positions the cable 40 covered with heat shrink tubing 60 and braided mesh tubing 70, preventing the cable 40 from shifting during the heat shrinking process.

[0039] By using two parallel snap-fit ​​components 30 to position the ends of the two heat shrink tubing 60 and the braided mesh tubing 70, the fixing effect of the heat shrink tubing 60 and the braided mesh tubing 70 is enhanced, further improving the positioning accuracy and stability of the cable 40. During the heat shrinking process, the ends of the two heat shrink tubing 60 and the braided mesh tubing 70 are accurately fixed, which better ensures the neat arrangement of the cable 40 and reduces the displacement of the cable 40 caused by uneven shrinkage of the braided mesh tubing 70 due to the heat shrink tubing 60 fixing it. This improves the assembly quality of the wire harness and the stability of signal transmission performance, while also increasing production efficiency and product consistency.

[0040] By setting two rows of positioning slots 311 on the snap-fit ​​seat 31 and correspondingly setting two fixing components 20, simultaneous positioning and processing of two sets of cables 40 is achieved. This design effectively utilizes the space of the fixture, improves the utilization rate of the equipment, reduces the operation time in the production process, and thus improves production efficiency. At the same time, since each fixing component 20 and snap-fit ​​component 30 can independently position and fix a set of cables 40, the positioning accuracy and product quality consistency of the two sets of cables 40 are guaranteed, meeting the requirements of large-scale production.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
