[0002] In fields such as communication equipment, automotive electronics, and industrial control, coaxial connectors are core components for signal and current transmission. Their connection stability, shock and vibration resistance, and assembly precision directly determine the operational reliability of the equipment.

[0003] However, the existing support structure design of coaxial connectors has the following obvious defects: the inner and outer shells of traditional coaxial connectors are mostly connected by a rigid nesting method, lacking a flexible buffer structure between the shells. When the equipment is subjected to vibration, impact, or thermal expansion and contraction caused by temperature changes, the rigid connection is prone to loosening or misalignment between the shells, which can lead to poor contact of internal conductive components such as terminals, causing problems such as signal transmission interruption, attenuation, or unstable current. In severe cases, it can even damage the connector, shorten the service life of the equipment, and restrict its application in fields with high vibration and high reliability requirements. Utility Model Content

[0004] Therefore, the technical problem to be solved by this utility model is to overcome the problem that the existing technology mostly adopts a rigid nesting method for connection, which lacks a flexible buffer structure between the sleeves, making it easy for the sleeves to become loose or misaligned, which in turn leads to poor contact of internal conductive components such as terminals, causing problems such as signal transmission interruption, attenuation or current instability. Thus, a coaxial connector and connector assembly are provided.

[0005] To solve the above-mentioned technical problems, this utility model provides a coaxial connector, comprising:

[0006] The support mechanism includes: a first sleeve, a second sleeve, and a first support, which are sequentially arranged from the outside to the inside. There is a first gap space between the first sleeve and the first support. The size of the first gap space is adapted to the second sleeve. The first end of the second sleeve is provided with a first elastic arm that abuts against the first sleeve and a second elastic arm that abuts against the first support.

[0007] A connecting mechanism includes a second support and a connector. The second support is disposed within a second housing. The second support and the first support have a second spacing space. One end of the connector is connected to the second support and the other end extends into the first support.

[0008] In one embodiment of the present invention, the second elastic arm includes a first bent portion and a first inclined portion connected sequentially to the first end of the second sleeve, wherein the end of the first inclined portion elastically abuts against the first support.

[0009] In one embodiment of the present invention, the end of the first inclined portion is further connected to a first anti-inclined portion, and the connection between the first inclined portion and the first anti-inclined portion abuts against the first support.

[0010] In one embodiment of the present invention, the connector is configured as a female terminal, one end of which is used to mate with a male terminal to be inserted and the other end is used to connect to an electrical device to be connected. The female terminal can be compressed or stretched along its length.

[0011] In one embodiment of the present invention, the second sleeve is provided with a first clearance hole adapted to the second elastic arm, a limiting member is formed at the first end of the second sleeve, the first support is provided with a slot, the limiting member abuts against the inner wall of the slot, and the second elastic arm and the first clearance hole are both provided on the limiting member.

[0012] In one embodiment of the present invention, a shielding ring is embedded in the first support, and the shielding ring extends into the slot with a shielding portion, and the limiting member abuts against the shielding portion.

[0013] In one embodiment of this invention, the first elastic arm and the second elastic arm extend in opposite directions.

[0014] In one embodiment of the present invention, the first elastic arm includes: a second bent portion, a second inclined portion, and a second reverse inclined portion connected sequentially to the first end of the second sleeve body. The second inclined portion extends toward the first sleeve body and abuts against the inner wall of the first sleeve body, and the second reverse inclined portion extends away from the first sleeve body.

[0015] In one embodiment of the present invention, the second support is provided with a sliding part, which is movably connected to the inner wall of the second body.

[0016] In one embodiment of the present invention, the outer side wall of the second support is provided with a protrusion, the second end of the second sleeve is provided with a relief groove and a third elastic arm, the protrusion and the third elastic arm are both accommodated in the relief groove, and the third elastic arm abuts against the protrusion.

[0017] This utility model also discloses a connector assembly, including the coaxial connector described above, and further including a male connector and / or electrical components for connecting the coaxial connector.

[0018] Compared with the prior art, the above-mentioned technical solution of this utility model has the following beneficial effects:

[0019] The coaxial connector described in this utility model employs a multi-layered coaxial nested structure consisting of a first sleeve, a second sleeve, and a first support, arranged from the outside in. A first elastic arm abuts against the first sleeve and a second elastic arm abuts against the first support are respectively provided on both sides of the first end of the second sleeve, forming a bidirectional elastic buffer system. When the connector is subjected to radial vibration or impact, the first elastic arm can absorb the radially outward force through deformation, while the second elastic arm can absorb the radially inward force. This bidirectional synergy counteracts the impact of external forces on the overall structure, preventing loosening or misalignment between the sleeves. This effectively solves the problem of poor shock resistance in traditional rigid nested structures, ensuring that the connector maintains a stable structural form even under complex working conditions such as vehicle bumps and industrial equipment vibrations.

[0031] Example

[0032] Reference Figures 1-8 As shown, a coaxial connector of this utility model includes:

[0033] The support mechanism includes: a first sleeve 1, a second sleeve 2 and a first support 4, which are sequentially arranged from the outside to the inside. There is a first gap space between the first sleeve 1 and the first support 4. The size of the first gap space is adapted to the second sleeve 2. The first end of the second sleeve 2 is provided with a first elastic arm 23 that abuts against the first sleeve 1 and a second elastic arm 24 that abuts against the first support 4.

[0034] The connecting mechanism includes a second support 3 and a connector 6. The second support 3 is disposed inside the second sleeve 2. The second support 3 and the first support 4 have a second spacing space. One end of the connector 6 is connected to the second support 3 and the other end extends into the first support 4.

[0035] The coaxial connector described in this utility model comprises a first sleeve 1, which is the outermost structure and serves as an overall protective and radial limiting element. Its inner wall is elastically connected to the outer wall of the second sleeve 2 via a first elastic arm 23. The first elastic arm 23 is integrally formed on the outer side of the first end of the second sleeve 2, extending radially outward and abutting against the inner wall of the first sleeve 1. It is made of a metal or engineering plastic with high elastic recovery properties and can buffer radial external forces through elastic deformation. The second sleeve 2 is located between the first sleeve 1 and the first support 4. A second elastic arm 24 is integrally formed on the inner side of its first end, extending radially inward and abutting against the inner wall of the first support 4, thus forming an elastic connection and improving its shock and impact resistance. The first support 4 is an inner structure with a channel for the extension of the connector 6. Its outer wall is elastically abutting against the inner wall of the second sleeve 2 via the second elastic arm 24. A first gap space is located between the first sleeve 1 and the first support 4, and its dimensions are adapted to the second sleeve 2 to ensure accurate radial positioning of the second sleeve 2.

[0036] The connecting mechanism includes a second support 3 and a connector 6. The second support 3 is located inside the cavity of the second housing 2; a second gap space is formed between the second support 3 and the first support 4, which is set according to the length of the connector 6 and installation requirements to prevent the connector 6 from being excessively squeezed or loosened. The connector 6 is made of a highly conductive metal material, with one end abutting against the inner wall of the second support 3, and the other end extending axially into the interior of the first support 4 to form a mating end for docking with external components, and the outer wall slidingly engaging with the inner wall of the first support 4.

[0037] When subjected to radial vibration or impact, the first elastic arm 23 and the second elastic arm 24 undergo elastic deformation according to the magnitude of the external force. When subjected to an outward radial force, the first elastic arm 23 compresses to generate an inward elastic restoring force to counteract the external force; when subjected to inward or outward radial forces, the second elastic arm 24 compresses to generate an outward elastic restoring force to buffer the impact and protect the connector 6. The connector 6 is stably connected to the support mechanism, preventing structural loosening that could lead to poor contact and ensuring stable transmission.

[0038] Reference Figure 7 As shown, the second elastic arm 24 includes a first bent portion 241 and a first inclined portion 242 sequentially connected to the first end of the second sleeve 2. The end of the first inclined portion 242 elastically abuts against the first support 4. The second elastic arm 24 and the first end of the second sleeve 2 are integrally molded to ensure structural integrity and strength, avoiding structural weaknesses caused by splicing. The second elastic arm 24 includes a first bent portion 241 and a first inclined portion 242 sequentially connected. The first bent portion 241 is connected to the edge of the first end of the second sleeve 2, with the bending direction radially inward along the second sleeve 2. The bending angle is designed according to the elastic performance requirements, forming a transition structure with elastic deformation capability; its wall thickness is consistent with that of the second sleeve 2, improving elasticity while ensuring strength.

[0039] The first inclined portion 242 is integrally connected to the end of the first bent portion 241 away from the second sleeve 2. Its extension direction is inclined away from the second sleeve 2 and towards the outer wall of the first support 4. Its length is determined according to the distance between the second sleeve 2 and the first support 4, ensuring effective contact between its end and the outer wall of the first support 4. A smooth transition surface is formed between the first inclined portion 242 and the first bent portion 241 to avoid stress concentration. The end of the first inclined portion 242 has a smooth arc-shaped structure, which matches the curved surface of the outer wall of the first support 4, increasing the contact area, reducing local pressure, and preventing wear on the outer wall of the first support 4 or deformation of the end of the second elastic arm 24.

[0040] In the assembled state, the end of the first inclined portion 242 contacts the outer wall of the first support 4 and undergoes pre-compression deformation. Both the first bent portion 241 and the first inclined portion 242 are in a pre-tightened state. The first bent portion 241 provides the main elastic restoring force, and the first inclined portion 242 ensures stable contact. When subjected to radial inward and outward forces, the first support 4 tends to move towards the second sleeve 2, further compressing the first inclined portion 242, increasing the degree of deformation of the first bent portion 241 and the first inclined portion 242, and increasing the elastic restoring force accordingly. This force acts in the opposite direction on the first support 4 to offset the external force, playing a buffering role. After the external force disappears, both return to the pre-tightened state under the action of the elastic restoring force, ensuring stable contact. When subjected to radial outward external forces, the first support 4 moves away from the second sleeve 2, the pressure on the first inclined portion 242 decreases, the degree of deformation decreases, and the elastic restoring force decreases, but it still maintains contact with the first support 4 to prevent structural loosening.

[0041] The end of the first inclined portion 242 is also connected to a first reverse inclined portion 243, and the connection between the first inclined portion 242 and the first reverse inclined portion 243 abuts against the first support 4. The first reverse inclined portion 243 is integrally connected to the end of the first inclined portion 242 away from the first bent portion 241, and its extension direction is opposite to that of the first inclined portion 242, that is, it is inclined towards the second body 2, forming a V-shaped or U-shaped bending structure; the connection between the first inclined portion 242 and the first reverse inclined portion 243 is a smooth bending transition, and the radius of curvature is designed according to the elastic performance and strength requirements to ensure uniform deformation under force and avoid stress concentration. The wall thickness of the first inclined portion 242 and the first reverse inclined portion 243 is the same as that of the first bent portion 241, and they are made of the same elastic material as the second body 2 to ensure uniform overall elastic performance.

[0042] In the assembled state, the connection point (bending transition point) between the first inclined portion 242 and the first reverse inclined portion 243 abuts against the outer wall of the first support 4, forming the main abutment area. The end of the first reverse inclined portion 243 away from the connection point maintains a certain gap with the inner wall of the second sleeve 2 to avoid interference. The length ratio of the first inclined portion 242 to the first reverse inclined portion 243 is determined according to the distance between the second sleeve 2 and the first support 4. Usually, the length of the first inclined portion 242 is greater than that of the first reverse inclined portion 243, ensuring that the connection point accurately abuts against the preset position of the first support 4. At the same time, when the deformation length is too large, the first reverse inclined portion 243 abuts against the inside of the second sleeve 2 to form additional elastic support, further providing additional support and preventing complete damage.

[0043] Reference Figures 3-5 As shown, the connector 6 is configured as a female terminal. One end of the female terminal is used to mate with the male terminal to be inserted, and the other end is used to connect to the electrical device to be connected. The female terminal can be compressed or stretched along its length. The connector 6 adopts a female terminal structure and is made of high-conductivity copper alloy, silver alloy, etc. The surface can be gold-plated or silver-plated to reduce contact resistance and improve conductivity and corrosion resistance. The female terminal is generally spiral cylindrical or tubular, with one end being the mating end. It has an internal cavity adapted to the male terminal to be inserted. The inner wall of the cavity can be provided with elastic contact pieces or protrusions to enhance the tightness of contact with the male terminal and prevent loosening. The mating end port is provided with a guide chamfer to facilitate the smooth insertion of the male terminal and reduce friction and damage.

[0044] Reference Figures 1-2 As shown, the other end of the female terminal is the connection end, which is connected to the electrical components to be connected, such as wires, circuit board 8, sensors, etc., by means of crimping, welding, threaded connection or injection molding. When connecting circuit board 8, the connection end is provided with welding pins, which are fixed to the pads of circuit board 8 by reflow soldering or manual soldering.

[0045] The middle part of the female terminal is the telescopic section, which adopts a spiral plate structure. The female terminal can be compressed or stretched along the length direction. The wall thickness of the telescopic section is designed according to the expansion and contraction amount and strength requirements to ensure that it does not break or deform excessively during expansion and contraction, while maintaining good conductivity. The outer wall of the telescopic section can be equipped with a protective sleeve or insulation layer to prevent short circuits or interference with other components.

[0046] The second sleeve 2 has a first clearance hole 26 adapted to the second elastic arm. A limiting member 25 is formed at the first end of the second sleeve 2. The first support 4 has a slot 42, and the limiting member 25 abuts against the inner wall of the slot 42. The second sleeve 2 has a first clearance hole 26 on its side wall, corresponding to the position of the second elastic arm 24, located near the first end of the second sleeve 2. The shape and size of the first clearance hole 26 are adapted to the second elastic arm 24, ensuring that the second elastic arm 24 can freely enter during deformation, avoiding interference with the side wall of the second sleeve 2. The edge of the clearance hole is rounded to prevent scratching or stress concentration damage to the second elastic arm 24 during deformation. The second sleeve 2 is stamped to form the second elastic arm 24 and the first clearance hole 26, with one end of the second elastic arm 24 connected to the inner wall of the first clearance hole 26.

[0047] The second set 2 extends radially inward from its first end to form a limiting member 25, which is a ring or multiple evenly distributed bent structures, integrally bent with the second set 2 to ensure structural strength. The end face of the limiting member 25 is concave relative to the side of the second set 2 to ensure insertion into the slot 42 and abutment. The first support 4 is embedded with a shielding ring 5, which is injection molded to prevent loosening or displacement due to vibration during use. At the same time, the shielding ring 5 and the first support 4 share space to reduce the structural size occupied, and shorten the distance between the shielding ring 5 and the connecting member 6 located inside it. The shielding ring 5 extends into the slot 42 to form a shielding part 51, and the limiting member 25 abuts against the shielding part 51. The end face or inner wall of the limiting member 25 abuts tightly against the inner wall of the shielding part 51 to form a surface contact fit, and both contact surfaces are polished to reduce contact resistance, ensuring that electromagnetic signals can be effectively conducted through the limiting member 25 and the shielding part 51, closing the shielding circuit.

[0048] Reference Figure 6 As shown, the outer wall of the first support 4 is surrounded by snap-fit ​​members 41, and the inner side of the snap-fit ​​members 41 is provided with a snap-fit ​​groove 42. The number and shape of the snap-fit ​​members 41 correspond to the limiting member 25, and the depth is adapted to the radial length of the limiting member 25. The inner wall of the groove 42, i.e., the bottom surface and the side surface, are smooth surfaces to reduce friction with the limiting member 25. In the assembled state, the limiting member 25 is inserted into the groove 42, and the outer wall of the groove 25 abuts tightly with the inner wall of the groove 42, forming a dual positioning in the axial direction and radial directions of the insertion direction; the second elastic arm 24 is adapted to the first clearance hole 26 and its deformation is not restricted by the side wall, so it can freely retract or extend.

[0049] The second elastic arm 24 and the first clearance hole 26 are both provided on the limiting member 25. The limiting member 25 is an annular protrusion structure that extends radially inward from the first end of the second body 2. The radial thickness is designed according to the size of the second elastic arm 24 and the depth of the first clearance hole 26 to ensure sufficient strength to support the second elastic arm 24 and the opening of the clearance hole.

[0050] The second elastic arm 24 is integrally bent into the inner wall of the limiting member 25, that is, the side close to the first support 4, and extends radially inward. The number can be set as needed to ensure uniform contact force on the first support 4. The root of the second elastic arm 24 smoothly transitions with the inner wall of the limiting member 25 to avoid stress concentration. The end shape is adapted to the outer wall of the first support 4 to ensure tight contact.

[0051] The first clearance hole 26 is formed on the side wall of the limiting member 25, corresponding one-to-one with the second elastic arm 24. Each second elastic arm 24 has a clearance hole on its outer side. The shape of the clearance hole is perfectly adapted to the second elastic arm 24, and its depth penetrates the radial thickness of the limiting member 25 to avoid interference with other parts of the limiting member 25. The edges of the clearance holes are rounded to prevent scratching and damage to the second elastic arm 24. In the assembled state, the limiting member 25 is inserted into the slot 42 of the first support 4, and its outer wall abuts against the inner wall of the slot 42 to achieve positioning. The second elastic arm 24 extends from the inner side wall of the limiting member 25 to abut against the outer wall of the first support 4. The first clearance hole 26 provides space for deformation. The three form an integrated structure and fit tightly together.

[0052] The first elastic arm 23 and the second elastic arm 24 extend in opposite directions. The first elastic arm 23 is integrally formed on the outer wall of the first end of the second sleeve 2, close to the side of the first sleeve 1, and extends radially outward along the second sleeve 2 towards the inner wall of the first sleeve 1, finally abutting against the inner wall of the first sleeve 1; the root of the first elastic arm 23 smoothly transitions with the outer wall of the second sleeve 2, and the end is an arc-shaped structure that matches the curved surface of the inner wall of the first sleeve 1, increasing the contact area.

[0053] The first elastic arms 23 are evenly distributed in the circumferential direction at the first end of the second body 2 to ensure uniform force on the circumference; the wall thickness, length and elastic coefficient of each first elastic arm 23 are designed according to the required elastic restoring force and are usually kept consistent to ensure that the elastic restoring forces are equal in magnitude and opposite in direction.

[0054] In the assembled state, the first elastic arm 23 is in a radially outward pre-tightened state, generating an inward elastic pressure on the first sleeve 1, and the first sleeve 1 generates an outward reaction force on it; the second elastic arm 24 is in a radially inward pre-tightened state, generating an outward elastic pressure on the first support 4, and the first support 4 generates an inward reaction force on it; because the extension directions are opposite, the two sets of reaction forces are in opposite directions, forming a mutually balanced state.

[0055] The first elastic arm 23 includes a second bent portion 231, a second inclined portion 232, and a second reverse inclined portion 233, which are sequentially connected to the first end of the second sleeve 2. The second inclined portion 232 extends towards the first sleeve 1 and abuts against the inner wall of the first sleeve 1, while the second reverse inclined portion 233 extends away from the first sleeve 1. The first elastic arm 23 is integrally formed with the first end of the second sleeve 2 and is made of the same material as the second sleeve 2. Each part of the first elastic arm 23 is arc-shaped and its size is larger than that of the second elastic arm 24. The second bent portion 231 is connected to the outer wall of the first end of the second sleeve 2, and the bending direction is radially outward along the second sleeve 2, forming an elastic deformation transition structure. The bending angle is designed according to the elastic requirements to ensure uniform deformation under force and avoid stress concentration. The wall thickness is the same as that of the second sleeve 2 to ensure structural strength.

[0056] The second inclined portion 232 is integrally connected to the end of the second bent portion 231 away from the second sleeve 2. The extension direction is inclined towards the inner wall of the first sleeve 1. The length is determined according to the distance between the second sleeve 2 and the first sleeve 1 to ensure that the end is in close contact with the inner wall of the first sleeve 1. The inner wall of the second inclined portion 232 and the inner wall of the second bent portion 231 are smoothly transitioned. The end is an arc-shaped structure that matches the curved surface of the inner wall of the first sleeve 1, increasing the contact area and reducing local pressure.

[0057] The second anti-sloping portion 233 is integrally connected to the end of the second inclined portion 232 away from the second bending portion 231. Its extension direction is opposite to that of the second inclined portion 232, that is, it extends away from the inner wall of the first sleeve 1, forming a wave-shaped bending structure. The length of the second anti-sloping portion 233 is shorter than that of the second inclined portion 232. The end away from the second inclined portion 232 maintains a gap with the outer wall of the second sleeve 2 to avoid interference. The wall thickness is the same as that of the second inclined portion 232 to ensure uniform elastic performance.

[0058] The second support 3 is provided with a sliding part 32, which is movably connected to the inner wall of the second sleeve 2. The sliding part 32 is integrally formed or injection molded on the outer wall of the second support 3. The structure of the sliding part 32 can be designed as a protruding block. The surface is polished to reduce the coefficient of sliding friction. The sliding parts 32 are evenly distributed on the outer wall of the second support 3, with 2-4 sets, to ensure that the second support 3 is subjected to balanced force during sliding and to avoid tilting or jamming. In the assembled state, the sliding part 32 abuts against the mating structure of the second sleeve 2, and the second support 3 can slide within a limited range along the extension direction of the mating structure, i.e., axially.

[0059] The outer side wall of the second support 3 is provided with a protrusion 31, and the second end of the second sleeve 2 is provided with a relief groove 21 and a third elastic arm 22. The protrusion 31 and the third elastic arm 22 are both accommodated in the relief groove 21, and the third elastic arm 22 abuts against the protrusion 31.

[0060] The protrusion 31 is adapted to the shape of the clearance groove 21 of the second body 2, and can be set as a block protrusion evenly distributed along the circumference; 2-4 sets of block protrusions are set and evenly distributed on the outer side wall of the second support 3 to ensure that the abutment force of the third elastic arm 22 on the protrusion 31 is evenly distributed. The material of the protrusion 31 is the same as that of the second support 3, and it has a certain structural strength, which can withstand the preload of the third elastic arm 22 and the impact force during use without deformation.

[0061] The second end of the second body 2, which is the end furthest from the first end, forms a radial clearance groove 21. The shape and size of the clearance groove 21 are adapted to both the protrusion 31 and the third elastic arm 22, ensuring that both can be completely accommodated within the groove without interference. The depth and width of the clearance groove 21 are designed according to the size of the protrusion 31, the thickness of the third elastic arm 22, and the deformation requirements, reserving sufficient space for the elastic deformation of the third elastic arm 22. The third elastic arm 22 is integrally formed on the inner wall of the clearance groove 21 and is made of metal or engineering plastic with high elastic recovery performance. It extends along the axial direction of the clearance groove 21, with its free end protruding into the clearance groove 21 to form an abutment structure adapted to the protrusion 31. The root of the third elastic arm 22 smoothly transitions to the inner wall of the clearance groove 21 to avoid breakage under stress. It is adapted to the outer wall of the protrusion 31 and its ends are bent and aligned to increase the contact area and reduce local pressure.

[0062] In the assembled state, the protrusion 31 is housed in the clearance groove 21, and the free end of the third elastic arm 22 elastically abuts against the outer wall of the protrusion 31 to form a pre-tightened state; the protrusion 31 maintains a gap with the inner wall of the clearance groove 21 to ensure that the protrusion 31 can move axially within a limited range under the elastic constraint of the third elastic arm 22, while avoiding rigid collision with the inner wall of the clearance groove 21.

[0063] This embodiment also provides a connector assembly, including the coaxial connector described above, and further including a male connector 9 and / or electrical components for connecting the coaxial connector.

[0064] The male connector 9, as a mating component that connects to the coaxial connector, is structurally designed to match the connection mechanism of the coaxial connector. It has male terminals corresponding to the coaxial connector connector 6, such as female terminals. The male terminals are made of highly conductive material, and their surfaces can be gold-plated or silver-plated to reduce contact resistance and improve conductivity and corrosion resistance. The shell structure of the male connector 9 is adapted to the support mechanism of the coaxial connector. The inner wall of the shell can be provided with positioning protrusions or guide structures to cooperate with the corresponding structure of the coaxial connector, ensuring accurate positioning during docking and avoiding misalignment. The tail of the male connector 9 has a cable 7 fixing structure to fix the transmission cable 7 and prevent the cable 7 from being pulled, which could lead to poor contact between the male and female terminals.

[0065] Electrical components are terminal parts that receive or transmit signals / currents, including but not limited to wires, circuit boards 8, sensors, controllers, etc. If the electrical component is a circuit board 8, the connection end of the connector 6 is fixed to the pad or slot of the circuit board 8 by soldering or plugging to ensure a stable conductive path. The connection part between the electrical component and the coaxial connector can be equipped with an insulating protective sleeve or a seal to improve insulation performance and sealing performance, and adapt to humid and dusty environments.

[0066] During component assembly, the male connector 9 and the mating end of the coaxial connector are precisely mated, and the male terminal is inserted into the mating end of the female terminal to form a conductive path. The male connector 9 is connected to the electrical equipment through the cable 7. The electrical component is fixedly connected to the connection end of the coaxial connector to complete the construction of the signal / current transmission path. Depending on the application requirements, the component may only include the coaxial connector and the male connector 9 to realize the mating between the two components, or it may only include the coaxial connector and the electrical component to introduce or lead in the signal / current of the electrical component, or it may include all three at the same time to form a complete transmission system of electrical component, coaxial connector and male connector 9.
