Description

Technical Field

[0001] This utility model relates to the technical field of coaxial cable pre-tensioning, and in particular to a coaxial cable pre-tensioning device. Background Technology

[0002] A coaxial cable is a type of cable used to transmit radio frequency signals. It consists of four parts: an inner conductor, an insulation layer, an outer conductor (shielding layer), and an outer protective sheath. The inner conductor is usually made of copper or copper-plated material and is responsible for transmitting signals; the insulation layer isolates the inner and outer conductors, ensuring stable signal transmission; the outer conductor acts as shielding, reducing external electromagnetic interference; and the outer protective sheath provides physical protection against damage.

[0003] Improper installation of coaxial cables can easily lead to various deviations, occupying space on the pre-set electronic equipment substrate and affecting the subsequent installation and arrangement of electronic components. If the bending radius of the coaxial cable is too small, it will not only damage the internal structure and affect the signal transmission quality, but may also cause the shielding layer to break, reducing the shielding effect and increasing the risk of signal leakage. Utility Model Content

[0004] This utility model aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this utility model is to propose a coaxial cable pre-tightening device to ensure accurate installation of the coaxial cable, effectively save internal space of electronic equipment, facilitate the subsequent arrangement and installation of electronic components; at the same time, it avoids damage to the coaxial cable due to excessively small bending radius, ensures stable signal transmission quality, maintains good shielding effect, significantly reduces the risk of signal leakage, and thus improves the performance and stability of the entire electronic equipment.

[0006] To achieve the above objectives, this utility model proposes a coaxial cable pre-tightening device, comprising a base plate, a coaxial cable, a pressure tongue mechanism, multiple connecting rings, multiple pulling mechanisms, and multiple tensioning mechanisms. The base plate has a first slot, and a second slot is formed on the side of the first slot. Multiple connecting rings are disposed at the bottom of the coaxial cable. The pressure tongue mechanism is mounted on the second slot. Multiple pulling mechanisms are disposed on the side walls of the first slot. Each pulling mechanism includes a compression spring, a slider, and a cavity. The cavity is disposed on the side wall of the second slot, and the slider is slidably disposed inside the cavity. One end of the compression spring is disposed at the bottom of the cavity, and the other end is disposed at the bottom of the slider. Multiple tensioning mechanisms are mounted on the pulling mechanisms.

[0007] The coaxial cable pre-tightening device of this invention ensures accurate installation of the coaxial cable, effectively saves internal space of electronic equipment, and facilitates the subsequent arrangement and installation of electronic components. At the same time, it avoids damage to the coaxial cable due to excessively small bending radius, ensures stable signal transmission quality, maintains good shielding effect, significantly reduces the risk of signal leakage, and thus improves the performance and stability of the entire electronic equipment.

[0009] Specifically, the pressing tongue mechanism includes a pressing tongue and a first torsion spring, wherein the pressing tongue has multiple heat dissipation grooves; the first torsion spring is installed between the two side walls of the second groove; and the pressing tongue is installed on the first torsion spring.

[0010] Specifically, the tensioning mechanism includes a crossbar, a vertical bar, a mounting hook, and a second torsion spring.

[0019] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention. Rather, the embodiments of the present invention include all variations, modifications, and equivalents falling within the spirit and scope of the appended claims.

[0020] The coaxial pre-tightening device of this utility model embodiment will be described below with reference to the accompanying drawings.

[0021] like Figure 1 As shown, the pre-tightening device for the coaxial cable 2 in this embodiment of the present invention may include a base plate 1, a coaxial cable 2, a tongue pressing mechanism 3, multiple connecting rings 4, multiple pulling mechanisms 5, and multiple tightening mechanisms 6.

[0022] The substrate 1 has a first slot 11, the side of the first slot 11 has a second slot 12, and multiple connecting rings 4 are disposed at the bottom of the coaxial line 2.

[0023] It should be noted that the connecting ring 4 described in the above embodiment is bonded to the bottom of the coaxial line 2 by adhesive bonding. The adhesive bonding method can be 3M adhesive or the like, so as to fix the pre-tightened position of the coaxial line 2, thereby preventing the coaxial line 2 from shifting.

[0024] The tongue-pressing mechanism 3 is installed on the second slot 12. It should be noted that the tongue-pressing mechanism 3 is used to press the coaxial line 2, thereby further ensuring the stability of the coaxial line 2.

[0025] Multiple pulling mechanisms 5 are disposed on both sides of the first slot 11. Each pulling mechanism 5 includes a compression spring 51, a slider 52, and a cavity shell 53.

[0026] The cavity shell 53 is disposed on the side wall of the second slot 12, and the slider 52 is slidably disposed inside the cavity shell 53; one end of the compression spring 51 is disposed at the bottom of the cavity shell 53, and the other end of the compression spring 51 is disposed at the bottom of the slider 52.

[0027] It should be noted that the slider 52 provided in the above embodiment can slide freely inside the cavity shell 53, and the compression spring 51 provided can pull the slider 52.

[0028] Furthermore, since multiple tensioning mechanisms 6 are installed on the pulling mechanism 5, the provided compression spring 51 can further pull the tensioning mechanism 6, further enhancing the stability of the coaxial line 2.

[0029] It should be noted that the number of connecting rings 4 is the same as the number of tensioning mechanisms 6, thus ensuring a one-to-one match between connecting rings 4 and tensioning mechanisms 6.

[0030] Specifically, when relevant personnel need to install the coaxial cable 2 onto the circuit board 1, they first move the coaxial cable 2 to a suitable position and attach the connecting ring 4 to the coaxial cable 2 at the position opposite to the first slot 11. Then, relevant personnel manually push the pressure tongue mechanism 3 upward and fasten the tensioning mechanism 6 onto the connecting ring 4.

[0031] Then, the relevant personnel slowly lowered the tongue-pressing mechanism 3 to press the coaxial cable, so that the part of the coaxial cable 2 with tolerance is inside the first slot 11, so as not to occupy the surface of the substrate 1.

[0032] This ensures precise installation of coaxial cable 2, effectively saves internal space in electronic devices, and facilitates the subsequent arrangement and installation of electronic components. At the same time, it prevents coaxial cable 2 from being damaged due to an excessively small bending radius, ensures stable signal transmission quality, maintains good shielding effect, significantly reduces the risk of signal leakage, and thus improves the performance and stability of the entire electronic device.

[0033] It should be noted that when fastening the tensioning mechanism 6 in the above embodiments, since the parts are small, it can be operated with tweezers and a magnifying glass.

[0034] In one embodiment of this utility model, such as Figure 1 and Figure 4 As shown, the tongue depressor 3 includes a depressor tongue 31 and a first torsion spring 32.

[0035] The pressing tongue 31 has multiple heat dissipation slots 311, and the first torsion spring 32 is installed between the two side walls of the second slot 12. The pressing tongue 31 is installed on the first torsion spring 32.

[0036] It should be noted that in the above embodiment, the first torsion spring 32 ensures that the pressing tongue 31 can return to its initial position, thereby enhancing the pressing effect on the coaxial line 2.

[0037] In one embodiment of this utility model, such as Figure 3As shown, the tensioning mechanism 6 includes a crossbar 61, a longitudinal bar 62, a mounting hook 63, and a second torsion spring 64.

[0038] One end of the crossbar 61 is connected to the slider 52, one end of the vertical bar 62 is connected to the other end of the crossbar 61, the mounting hook 63 is set on one end of the vertical bar 62, and a second torsion spring 64 is provided between the mounting hook 63 and the vertical bar 62.

[0039] It should be noted that the mounting hook 63 is rotatable on the longitudinal rod 62, and the second torsion spring 64 is used to hook the connecting ring 4 so as to cooperate with the pulling mechanism 5 to maintain a stable connection to the connecting ring 4.

[0040] Specifically, when the rotating mounting hook 63 hooks the connecting ring 4, the mounting hook 63 and the connecting ring 4 are connected, thereby ensuring that the coaxial line 2 is stably located inside the first slot 11. At the same time, when the mounting hook 63 is released, the second torsion spring 64 can make the mounting hook 63 move closer to the vertical rod 62, and the compression spring 51 can pull the slider 52, so that the coaxial line 2 can be stably located inside the substrate 1.

[0041] In summary, the coaxial cable pre-tightening device of this utility model ensures accurate installation of the coaxial cable, effectively saves internal space of electronic equipment, and facilitates the subsequent arrangement and installation of electronic components; at the same time, it avoids damage to the coaxial cable due to excessively small bending radius, ensures stable signal transmission quality, maintains good shielding effect, significantly reduces the risk of signal leakage, and thus improves the performance and stability of the entire electronic equipment.
