[0028] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0030] Example 1

[0031] This embodiment provides a female seat mechanism, such as Figure 1 As shown, it includes a female socket housing 2, a terminal assembly 1 and a fixing member 3. The terminal assembly 1 and the fixing member 3 are arranged in the female socket housing 2, and the terminal assembly 1 is connected to the female socket housing 2 through the fixing member 3.

[0032] Based on the above structure, the female socket mechanism limits and protects the terminal assembly 1 through the fixing part 3, and connects the terminal assembly 1 and the female socket shell 2 through the fixing part 3 to ensure the connection stability between the two, making it difficult to separate in environments such as high vibration, and has a good transmission effect when used in circular connectors.

[0033] In some embodiments of the present application, one end of the fixing member 3 extends into the female socket shell 2 and is connected to the terminal assembly 1, and the other end is formed with a bending portion 31, and the bending portion 31 is connected to the end of the female socket shell 2. The end of the female socket shell 2 is clamped in the bending portion 31. By providing the bending portion 31 and connecting it to the female socket shell 2, the connection strength between the fixing member 3 and the female socket shell 2 is increased. By clamping the end of the female socket shell 2 in the bending portion 31, the contact area between the female socket shell 2 and the bending portion 31 is increased, the friction between the two is increased, and the two are made more difficult to separate.

[0034] In some embodiments of the present application, Figure 3 As shown, the bending portion 31 is U-shaped and is locked with the end of the female base shell 2 in an interference fit manner, that is, the size of the part of the female base shell 2 extending into the bending portion 31 is slightly larger than the opening size of the bending portion 31. The bending portion 31 can limit the end of the female base shell 2 to avoid separation of the two under the action of external force, thereby ensuring the use effect of the female base mechanism in high vibration environments.

[0035] Preferably, the bending portion 31 and the mother seat shell 2 are ultrasonically connected or bonded. During ultrasonic connection, high-frequency vibration waves are transmitted to the contact point between the bending portion 31 and the mother seat shell 2, and under pressure, the surfaces of the two are rubbed against each other to form fusion between the molecular layers, thereby further improving the connection strength between the fixing part 3 and the mother seat shell 2; during bonding, the connection strength between the fixing part 3 and the mother seat shell 2 is improved by using glue, adhesives, etc.

[0036] In some embodiments of the present application, Figure 4 As shown, the terminal assembly 1 includes an insulator 11 and a terminal body 12 provided on the outer circumferential wall thereof.

[0037] This embodiment uses the outer circumferential wall of the insulator 11 as the assembly area of the terminal body 12. On the one hand, it can avoid the limitation of the operating space caused by the array of the terminal body 12 passing through the insulator 11, and facilitate the use of automated methods to assemble the terminal body 12 and the insulator 11, thereby improving assembly efficiency; on the other hand, by increasing the assembly space, the number of terminal bodies 12 assembled on the insulator 11 of the same size can be increased, or the size of the insulator 11 when assembling the same number of terminal bodies 12 can be reduced, thereby reducing the size of the female seat mechanism and expanding its scope of use.

[0038] In some embodiments of the present application, a limiting groove 13 adapted to the terminal body 12 is further provided on the outer circumferential wall of the insulator 11 , and the terminal body 12 is located in the limiting groove 13 .

[0039] Specifically, the shape and number of the limiting grooves 13 are adapted to those of the terminal body 12 .

[0040] This embodiment increases the stability of the connection between the terminal body 12 and the insulator 11 through the limiting groove 13, and ensures that when the terminal assembly 1 is assembled in the fixing part 3, the outer circumferential wall of the insulator 11 and the inner circumferential wall of the fixing part 3 can form a sealing structure to prevent water vapor, dust, etc. from entering the female seat mechanism from here.

[0041] In some embodiments of the present application, Figure 5 As shown, the end of the terminal body 12 is flat, or the end of the terminal body 12 extends along the radial direction of the insulator 11 to form a bent portion 121, or the end of the terminal body 12 is formed with a protrusion 122.

[0042] Specifically, the terminal body 12 is a flat strip-shaped structure as a whole, which can be prepared by a stamping process, breaking the limitation that the existing cylindrical terminal body can only be prepared by a turning process, thereby improving the production efficiency of the terminal body 12, reducing production costs, and reducing the size of the terminal body 12, thereby reducing the size of the terminal assembly 1 and the female seat mechanism, and expanding its scope of use.

[0043] By setting the end of the terminal body 12 to be flat, or forming a bent portion 121 and a raised portion 122, it is interference fit with the bent portion 121, raised portion 122 or flat end corresponding to the terminal body 12 on the male head mechanism, so as to improve the stability of power supply, signal and data transmission using the female seat mechanism and the male head mechanism.

[0044] In some embodiments of the present application, there are at least two terminal bodies 12, and at least two terminal bodies 12 are arranged at intervals on the outer circumferential wall of the insulator 11. The terminal body 12 is prepared by a stamping process to reduce its size, and the assembly space on the outer circumferential wall of the insulator 11 is larger. Therefore, the number of terminal bodies 12 can be determined according to user needs, and is less restricted by size and assembly space.

[0045] In some embodiments of the present application, the terminal assembly 1 further includes a coaxial assembly 14 , which is disposed within the insulator 11 ; specifically, the coaxial assembly 14 is disposed along the axis of the insulator 11 .

[0046] This embodiment provides the coaxial component 14 to ensure that when the terminal component 1 is used in a radio frequency device, there is sufficient impedance matching between the terminal component 1 and the radio frequency device, and the use effect is good.

[0047] The number of coaxial components 14 is determined according to the user's needs, and one or two groups can be selected.

[0048] In some embodiments of the present application, Figure 2 As shown, a protective member 4 is also provided on the female base housing 2;

[0049] The protective member 4 includes an outer protective ring 41 and an inner protective ring 42 . The outer protective ring 41 is arranged on the outer wall of the female base housing 2 , and the inner protective ring 42 is arranged on the inner wall of the female base housing 2 .

[0050] Specifically, an annular protrusion is provided on the outer wall of the female base housing 2, and the outer protective ring 41 is provided beside the annular protrusion.

[0051] When the female seat mechanism and the male head mechanism are plugged in, the male head mechanism abuts against the inner protective ring 42 to form a sealing structure, which can prevent rainwater and dust from entering the connector from the connection; when the female seat shell 2 in the female seat mechanism is connected to the device, the outer protective ring 41 abuts against the device, forming a sealing structure at the connection between the two, which prevents rainwater and dust from entering the interior of the device from the connection, thereby ensuring the waterproof and dustproof effect of the female seat mechanism.

[0052] In some embodiments of the present application, a nut 5 is threadedly connected to the outer wall of the female base housing 2 .

[0053] After the external thread provided on the outer wall of the female base shell 2 is connected to the thread of the device chassis, the annular protrusion is snapped into the device chassis, and the outer protective ring 41 next to the annular protrusion abuts against the device chassis to prevent the entry of moisture, dust, etc. In order to prevent the female base shell 2 from slipping out of the device chassis after long-term use, the nut 5 is threadedly connected to the outer wall of the female base shell 2 to snap it into the device chassis and will not separate under high vibration conditions.

[0054] The method of using the female seat mechanism provided in this embodiment is specifically as follows: before use, a plurality of terminal bodies 12 are prepared by a stamping process, and the plurality of terminal bodies 12 are spaced apart in the limiting grooves 13 on the outer circumferential wall of the insulator 11 to obtain a terminal assembly 1; the terminal body 12 obtained by stamping is smaller in size, and the circumferential assembly space of the insulator 11 is the largest, so that the size of the terminal assembly 1 with the same number of terminal bodies 12 in the present invention is smaller than that of the conventional terminal assembly, and the scope of use is expanded; when the terminal bodies 12 are circumferentially arranged on the outer circumferential wall of the insulator 11, the terminal bodies 12 will not interfere with each other, and it is convenient to use automatic welding to weld wire at the end of the terminal body 12.

[0055] The terminal assembly 1 is inserted into the fixing part 3, and then one end of the fixing part 3 is extended into the female housing 2 and connected to the terminal assembly 1 and the female housing 2, and the other end is extended to the outside of the female housing 2 and forms a U-shaped bending portion 31. The bending portion 31 is covered on the female housing 2 and is connected to the female housing 2 through ultrasonic technology, bonding technology, etc., which increases the connection stability between the terminal assembly 1 and the female housing 2, so that when it is applied to the circular connector, the transmission effect of the circular connector is good.

[0056] Example 2

[0057] This embodiment provides a female seat mechanism, such as Figure 6 、 Figure 7 As shown, it includes a female socket housing 2, a terminal assembly 1 and a fixing member 3. The terminal assembly 1 and the fixing member 3 are arranged in the female socket housing 2, and the terminal assembly 1 is connected to the female socket housing 2 through the fixing member 3.

[0058] In some embodiments of the present application, the fixing member 3 is connected to the female base shell 2 by a snap-fit manner; a card block 32 is provided on the fixing member 3, and a card slot 21 that cooperates with the card block 32 is provided on the female base shell 2; or a card block 32 is provided on the female base shell 2, and a card slot 21 that cooperates with the card block 32 is provided on the fixing member 3.

[0061] The terminal assembly 1 is inserted into the fixing part 3, and then the fixing part 3 is extended into a specific position in the female socket shell 2, so that the clamping block 32 is clamped in the clamping groove 21 to achieve a stable connection between the fixing part 3 and the female socket shell 2, thereby achieving a stable connection between the terminal assembly 1 and the female socket shell 2.
