Description

Technical Field

[0001] The utility model relates to the technical field of coaxial cables, in particular to a pile-connected coaxial cable connection component. Background Art

[0002] Coaxial cable is mainly used to transmit radio frequency and microwave signals and plays the role of signal interconnection. It is widely used in test and measurement, radar, electronic countermeasures, aviation and navigation, national defense and military industry, wireless communications and other applications.

[0003] Cable assemblies usually consist of two parts: a cable connector and a coaxial cable. There are usually two ways to connect a cable connector and a coaxial cable on the market. One is welding, that is, directly connecting and assembling the inner and outer conductors of the coaxial cable and the inner and outer conductors of the cable connector by welding. The other way is crimping, where the inner conductor of the coaxial cable is welded to the inner conductor of the cable connector, and the outer conductor is installed by squeezing a steel ring that is sleeved on the outer conductor of the coaxial cable and the outer conductor of the cable connector, forcing the outer conductor of the coaxial cable to contact the outer conductor of the cable connector.

[0004] However, the problem is that after the cable assembly is assembled through the above two methods, it is basically difficult to repair and adjust, especially the crimping assembly, which is basically a one-time thing. For example, when testing the performance of the cable assembly, the measurement is performed after the assembly is completed. Generally, it is found that the indicators are not good enough. If the welded or crimped cable assembly wants to be adjusted, it cannot be disassembled and reassembled at this time.

[0005] Therefore, the above problems need to be solved urgently by those skilled in the art. Utility Model Content

[0006] In order to solve the technical defects raised in the above-mentioned background technology, the purpose of the utility model is to provide a pile-connected coaxial cable connection component, which can be easily assembled and disassembled when the coaxial cable is repaired or adjusted, thereby avoiding material loss.

[0007] The utility model adopts the following technical solutions:

[0008] A stake-type coaxial cable connection assembly comprises a cable body and pins electrically connected to both ends of an inner conductor of the cable body. The outer rings of both ends of the cable body are sleeved with welding stakes and fasteners sleeved on the two welding stakes.

[0009] Optionally, the two fasteners each include an inner thread sleeve sleeved on the welding pile, and an outer thread sleeve threadedly connected to the inner thread sleeve.

[0010] Optionally, the welding pile has a convex ring at an edge position of one end facing the outer screw sleeve, and one end of the inner screw sleeve facing the outer screw sleeve abuts against the convex ring.

[0011] Optionally, the centers of the two outer screw sleeves each have a through hole, and the end of the ejector pin away from the end electrically connected to the inner conductor of the cable body passes through the through hole.

[0012] Optionally, an insulating sheet is provided between the ejector pin and both end surfaces of the cable body.

[0013] Optionally, both ejector pins are provided with insulating columns for insulating from the outer screw sleeve.

[0014] In summary, the beneficial effects of the utility model are:

[0015] By electrically connecting the pins at both ends of the inner conductor of the cable body, the electrical signals of the inner conductor can be transmitted to the external device, thereby realizing communication. At the same time, welding piles are sleeved at the two end positions of the cable body, so as to facilitate the assembly between the fasteners and the cable body. At the same time, by setting the fasteners, the cable body can be easily disassembled and assembled, so that the cable body can be easily replaced and repaired, avoiding the loss of wire materials.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood by specific circumstances.

[0026] like Figures 1 to 4 As shown, an embodiment of the present application provides a post-connected coaxial cable connection assembly, including a cable body 1, and also includes a pin 2 electrically connected to the two ends of the inner conductor of the cable body 1, and the outer rings of the two ends of the cable body 1 are both sleeved with welding piles 3 and fasteners 4 sleeved on the two welding piles 3.

[0027] In the embodiment of the present application, the above-mentioned cable body 1 can be a coaxial cable, which is used to transmit signals. The cable body 1 can include an inner conductor (inner conductor, a carrier for transmitting information), an insulating medium, an outer conductor, and an outer sheath from the inside to the outside. Both ends of the cable body 1 are electrically connected with a pin 2, which may be made of metal and is used to transmit signals. Specifically, the pin 2 is electrically connected to the inner conductor in the cable body 1, so that the signal of the inner conductor in the cable body 1 can be transmitted to the pin 2, and the pin 2 is then transmitted to an external device. The outer rings (outer sheaths) of the two end positions of the cable body 1 are sleeved with welding piles 3, and the surrounding wall of the welding piles 3 has two tin injection holes, and solder can be spot-welded in the spot welding holes, so that the welding piles 3 can be better fixed to the cable body 1. Furthermore, the outer ring of the welding piles 3 can be sleeved with fasteners 4, which can be loosened or tightened by threaded connection, so that when the cable body 1 is tested or needs to be repaired, it can be directly replaced by loosening the fasteners 4, thereby avoiding the entire coaxial cable being scrapped by welding or crimping, and it can also be reassembled, thereby greatly reducing material loss.

[0028] Optional, such as Figure 1 , Figure 2 and Figure 3 As shown, the two fasteners 4 both include an inner thread sleeve 41 which is sleeved on the welding pile 3 and moves on the outer ring of the cable body 1 , and an outer thread sleeve 42 which is threadedly connected to the inner thread sleeve 41 .

[0029] In the embodiment of the present application, the fastener 4 may include an inner screw sleeve 41 and an outer screw sleeve 42, the inner screw sleeve 41 may be sleeved on the cable body 1 and may be movable, and abut against the convex ring 31 of the welding pile 3, the outer screw sleeve 42 may be threadedly connected with the inner screw sleeve 41, so as to be assembled, wherein it should be noted that the installation sequence is first to sleeve the inner screw sleeve 41 on the outermost circle of the cable body 1 and be movable on it, and then weld the welding pile 3 on the outer conductor of the cable body 1, and then insert the welding pile 3 into the coaxial cable 1. Cable, keep the end face of the welding pile 3 and the end face of the cable flush, inject solder from the tin injection hole of the welding pile 3, use a resistance soldering iron to heat and weld, so that the molten solder evenly fills the gap between the welding pile 3 and the outer conductor of the cable body 1, and then slide the inner screw sleeve 41 to the convex ring 31 part of the outermost circle of the welding pile 3, so that it can be threadedly connected with the outer screw sleeve 42. Through the above method, only the inner screw sleeve 41 and the outer screw sleeve 42 need to be twisted to repair the interior or replace the material, avoiding the loss of materials caused by traditional methods (welding and crimping).

[0030] Optional, such as Figure 3 or Figure 4As shown, a convex ring 31 is provided at the edge of one end of the welding pile 3 facing the outer screw sleeve 42 , and one end of the inner screw sleeve 41 facing the outer screw sleeve 42 abuts against the convex ring 31 .

[0031] In the embodiment of the present application, the above-mentioned convex ring 31 is arranged on the outer ring wall of the welding pile 3 and away from the end that is sleeved with the cable body 1. By setting the convex ring 31, the inner screw sleeve 41 can be prevented from directly falling off from the cable body 1, and the inner screw sleeve 41 can be limited, so that it can be more stable when threadedly connected with the outer screw sleeve 42.

[0032] Optional, such as Figure 3 As shown, the centers of the two outer screw sleeves 42 each have a through hole 421 , and one end of the ejector pin 2 away from the end electrically connected to the inner conductor of the cable body 1 passes through the through hole 421 .

[0033] In the embodiment of the present application, the two outer screw sleeves 42 are arranged at the two ends of the cable body 1. Since the ejector pin 2 needs to contact the external device, the through hole 421 is provided to allow the ejector pin 2 to extend out, thereby better making electrical contact with the external device.

[0034] Optional, such as Figure 4 As shown, insulating sheets 5 are provided between the two ejector pins 2 and both end surfaces of the cable body 1 .

[0035] In the embodiment of the present application, the above-mentioned insulating sheet 5 is arranged between the two pins 2 and the two end faces of the cable body 1. The insulating sheet 5 can be rubber or plastic or glass or ceramic tile. The insulating sheet 5 is circularly sleeved on the pin 2 close to the end of the cable body 1. By setting the insulating sheet 5, the pin 2 can be isolated from the external current of the cable body 1, so that the signal transmission between the inner conductor in the cable body 1 and the pin 2 can be better.

[0036] Optional, such as Figure 3 and Figure 4 As shown, both ejector pins 2 are provided with insulating posts 6 for insulating from the outer screw sleeve 42 .

[0037] In the embodiment of the present application, the above-mentioned insulating column 6 is hollow and is sleeved on the middle position of the ejector pin 2. The above-mentioned insulating column 6 can also be made of rubber or plastic or glass or ceramic tile. By providing the insulating column 6, the ejector pin 2 and the outer screw sleeve 42 can be insulated, thereby preventing the electrical signal from being transmitted to the outer screw sleeve 42, thereby avoiding affecting the transmission of the electrical signal.

[0038] The embodiments of this specific implementation are all preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. The same components are represented by the same figure marks. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the protection scope of the present application.
