The contact head can elastically expand and contract in the outer sleeve under the action of an external force and the elastic member.

[0011] In some embodiments, one end of the contact head located in the outer sleeve is open, and the end extending out of the outer sleeve is closed.

[0036] For the convenience of understanding the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative work belong to the scope of protection of the present application.

[0037] For the convenience of understanding the present application, the present application will be described in more detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] An embodiment of the present application provides a coaxial connector. Please refer to Figures 1 to 5 , the coaxial connector 10 includes a housing 100, an insulator 200, a conductive terminal 300, and a cable 400. The insulator 200 is disposed within the housing 100, and the conductive terminal 300 is disposed within the insulator 200. The housing 100 can be made of a metal material and serves as a shield. The insulator 200 insulates between the housing 100 and the terminal, thereby preventing the terminal from contacting the metal housing 100. The conductive terminal 300 is electrically connected to the cable 400.

[0039] As Figure 3 and Figure 5 shown, the housing 100 includes a support portion 110 and a cylindrical portion 120. The support portion 110 extends along the conductive terminal 300 and the cable 400 and can support the conductive terminal 300 and the cable 400. As Figure 3 shown, the cylindrical portion 120 extends from the support portion 110 in the insertion direction. One end of the terminal is used to contact the connector, and the other end is connected to the cable 400. Define the end of the terminal for connecting to the docking connector 20 as the contact end T. As Figure 3 shown, the contact end T is located in the cylindrical portion 120 of the housing 100. As Figure 12 shown, when the docking connector 20 is connected to the cylindrical portion 120 of the housing 100, the docking terminal 230 of the docking connector 20 can contact the contact end T to achieve electrical connection.

[0040] In an embodiment of the present application, as Figure 3 and Figure 4 shown, the end of the cylindrical portion 120 is provided with a flanging 130, and the flanging 130 includes a bending portion 131 and a slot portion 132. One end of the bending portion 131 is connected to the cylinder of the cylindrical portion 120, and the other end is connected to the slot portion 132. As Figure 12 shown, the slot portion 132 is used to connect the docking connector 20. When the docking connector 20 is inserted into the slot portion 132, the docking connector 20 can be connected to the coaxial connector 10.

[0041] In the embodiment of the present application, the flanging 130 at the end of the cylindrical part 120 of the housing 100 of the coaxial connector 10 includes a bending part 131 and a slot part 132. Due to the setting of the bending part 131, when the docking connector 20 is connected to the flanging 130, the entire connection structure has a certain elasticity, realizing the elastic connection between the coaxial connector 10 and the docking connector 20, avoiding the problems of unstable connection and poor connection reliability caused by hard connection in the prior art, and improving the connection reliability. At the same time, due to the setting of the slot for plugging with the docking connector 20, the stability of the connection is further improved, and the biting force is strong. The coaxial connector 10 in the embodiment of the present application is a coaxial connector 10 for automobiles, and of course, it can be applied to other similar coaxial connectors 10. The inside of an automobile is often in a vibrating environment. Therefore, higher requirements are placed on the stability of the connector connection. The elastic connector structure in the embodiment of the present application can well meet the requirements of automobile connectors.

[0042] As Figure 3 and Figure 4 shown in the embodiment, the flanging 130 is S-shaped and has two bends. In other embodiments, as Figure 8 shown, the flanging 130 can also be wavy and have multiple bends.

[0043] As Figure 3 and Figure 4 shown in the embodiment, the flanging 130 is an S-shaped bend outward from the cylindrical part 120. In other embodiments, as Figure 9 shown, the flanging 130 can also be an S-shaped bend inward from the cylindrical part 120.

[0044] The flanging 130 can be directly formed by bending the cylindrical part 120 outward integrally, or can be formed by other materials and then installed on the cylindrical part 120 after forming the flanging 130 including the bending part 131 and the slot part 132, which is not limited here. In the embodiment of the present application, as Figure 3 and Figure 4 shown, the housing 100 is integrally formed by metal stamping or bending processes, that is, the flanging 130, the cylindrical part 120, and the support part 110 are integrally formed.

[0045] In an embodiment, as Figure 4 shown, the flanging 130 is S-shaped. The structure of the flanging 130 is to bend outward from the end of the cylinder of the cylindrical part 120, then bend to the same side of the coaxial connector 10, then bend outward, and then bend to the opposite side of the coaxial connector 10. As Figure 12 shown, here "the same side of the coaxial connector 10" and "the opposite side of the coaxial connector 10" respectively refer to the side of the coaxial connector 10 away from the docking connector 20 and the side close to the docking connector 20.

[0046] In one embodiment, as Figure 4 shown, the slot portion 132 includes two side walls (1321, 1322) and a bottom wall 1323 connecting the two side walls (1321, 1322). It can be understood that the notch of the slot portion 132 faces the docking connector 20, so that the docking connector 20 can be inserted into the slot portion 132. As Figure 4 shown, one ends of the two side walls (1321, 1322) connected to the bottom wall 1323 are inclined towards the center of the cylindrical portion 120, that is to say, the roots of the side walls (1321, 1322) are inclined towards the cylindrical portion 120. Among the two side walls (1321, 1322), the side wall far from the cylinder of the cylindrical portion 120 is the first side wall 1321, and the side wall close to the cylinder of the cylindrical portion 120 is the second side wall 1322. As Figure 4 shown, the inclination of the first side wall 1321 towards the cylindrical portion 120 makes the first side wall 1321 have a guiding function to guide the insertion of the docking connector 20. The second side wall 1322 is inclined towards the cylindrical portion 120, and a convex portion D can be formed at the notch of the slot portion 132, and the convex portion D can clamp the docking connector 20. As Figure 12 shown, the inner wall of the insertion cylinder 220 of the docking connector 20 is stuck on the convex portion D.

[0047] Furthermore, continuing to refer to Figure 4 , among the two side walls (1321, 1322) of the slot portion 132, the side wall (the second side wall 1322) close to the cylinder of the cylindrical portion 120 is inclined towards the center of the cylindrical portion 120 until it abuts against the cylinder of the cylindrical portion 120. As Figure 4 shown, the second side wall 1322 is basically inclined to the position where it abuts against the cylinder, so that the slot portion 132 abuts against the cylinder of the cylindrical portion 120, avoiding the slot portion 132 from being suspended, so that the connection is more stable after the docking connector 20 is inserted into the slot portion 132.

[0048] In one embodiment, the conductive terminal 300 is elastically designed. As Figure 6 and Figure 7 shown, the contact end T of the conductive terminal 300 includes an outer sleeve 310, a contact head 320 and an elastic member 330. The contact head 320 is slidably arranged in the outer sleeve 310, so that the contact head 320 can slide in the outer sleeve 310. The elastic member 330 is arranged in the outer sleeve 310, and the elastic member 330 is connected to the contact head 320. The contact head 320 can elastically expand and contract in the outer sleeve 310 under the action of an external force and the elastic member 330, so as to realize the elastic contact between the contact head 320 and the docking terminal 230 and ensure the reliability of the contact. At the same time, the elastic design of the conductive terminal 300 enables the conductive terminal 300 to be used as a test probe.

[0049] The elastic member 330 can be a spring or other elastic members, which is not limited herein.

[0050] Further, as Figure 7 shown, one end of the contact head 320 located in the outer sleeve 310 is open, and the end extending out of the outer sleeve 310 is closed. This not only facilitates the assembly with the elastic member 330, but also enables the closed end to better contact the docking terminal 230.

[0051] Further, as Figure 7 shown, one end of the elastic member 330 abuts against the bottom of the outer sleeve 310, and the other end abuts against the closed end of the contact head 320. The contact head 320 is buckled on the elastic member 330. This not only helps to utilize the internal space of the contact head 320 to accommodate the elastic member 330, but also enables the elastic member 330 to be located directly below the contact head 320, making the thrust of the elastic member 330 on the contact head 320 more uniform, so that the contact head 320 contacts the docking terminal 230 more stably and avoids the contact head 320 from being pressed out of shape.

[0052] In the embodiment of the present application, as Figure 3 shown, the contact end T is cylindrical, the contact end T is coaxially arranged with the cylindrical portion 120, and the axis is I. The cable 400 is a coaxial cable 400.

[0053] The embodiment of the present application also discloses a docking connector 20. As Figures 10 to 12 shown, the docking connector 20 is used to cooperate with the above-mentioned coaxial connector 10. As Figure 10 shown, the docking connector 20 includes an insulating base 210, a plug-in cylinder 220 and a docking terminal 230. The plug-in cylinder 220 and the docking terminal 230 are both arranged on the insulating base 210, and the docking terminal 230 is located inside the plug-in cylinder 220. The insulating base 210 insulates between the plug-in cylinder 220 and the docking terminal 230. As Figure 12 shown, the plug-in cylinder 220 can be inserted into the slot portion 132, so that the docking connector 20 is connected to the coaxial connector 10. As Figure 12 shown, after connection, the docking terminal 230 of the docking connector 20 contacts the conductive terminal 300 of the coaxial connector 10 to achieve electrical connection. Since the conductive terminal 300 is an elastic structure, it can elastically contact the docking terminal 230, and the contact effect is better. Moreover, the flanging 130 of the outer shell 100 of the coaxial connector 10 is also an elastic structure including a bending portion 131 and a slot portion 132, which can be firmly connected to the plug-in cylinder 220 of the docking connector 20, has a strong biting force, high connection reliability, and is not easy to loosen.

[0054] The plug-in cylinder 220 is made of metal and the plug-in cylinder 220 is grounded. After the plug-in cylinder 220 is connected to the flanging 130 of the coaxial connector 10, the outer shell 100 of the coaxial connector 10 is grounded. Under the strong biting force of the flanging 130, the grounding effect of the outer shell 100 is also better.

[0055] As Figure 12 shown, similar to the coaxial line connector 10, the docking terminal 230 of the docking connector 20 and the insertion cylinder 220 are also coaxial, and the axis is I. It can also be understood that the docking connector 20 and the coaxial line connector 10 are coaxial, and the axis is I.

[0056] In the description of the present application, unless otherwise clearly specified and limited, the terms "connected" and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be directly connected, or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the meanings of the above terms in the present application can be understood according to specific circumstances.

[0057] In the description of this embodiment, the orientation or positional relationship terms such as "upper", "lower", "front", and "rear" are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of description and simplifying the operation, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present application. The terms "first" and "second" are only used for distinction in description and have no special meaning.
