Specific Embodiments

[0050] Please refer to Figures 1 - 4, which is an electrical connector assembly 1000 according to the first embodiment disclosed in the present invention. It includes an electrical connector 100 and a docking connector 200. After the two connectors are docked, high-frequency signal transmission is completed. The two connectors are locked by their respective locking portions, and the specific structure will be introduced below.

[0051] Refer to Figures 2 - 3 and Figure 8 , the electrical connector 100 includes a housing 10 and a conductive component 20. The conductive component 20 includes an inner conductor 21 and a cable 22 connected to the rear end of the inner conductor 21. Among them, the inner conductor 21 is a female terminal with a jack. The housing 10 includes a main housing 11 and a rear end cover 12 connected to the rear end of the main housing 11. Among them, the main housing 11 is provided with a receiving cavity 110 penetrating in the front-rear direction. The main housing 11 is provided with a plurality of elastic arms 111 extending from front to back in the receiving cavity 110. The elastic arms 111 are provided with abutting portions 112. The conductive component 20 is provided with a fixing member 201, and the conductive component 20 is installed into the main housing 11 from the rear end of the receiving cavity 110. The abutting portion 112 of the elastic arm 111 presses forward against the fixing member 201 to initially limit the backward movement of the conductive component 20 provided with the fixing member 201. To make the fixing of the elastic arm 111 to the conductive component 20 more stable and reliable, the electrical connector 100 includes a limiting member 51. The limiting member 51 presses against the gap between the elastic arm 111 and the inner wall of the receiving cavity 110 to limit the elastic deformation of the elastic arm 111 and prevent the abutting portion 112 from separating from the limiting member 51.

[0052] Combined with Figure 5 , preferably, in this embodiment, the abutting portion 112 is a hook portion provided at the end of the elastic arm 111. The fixing member 201 is injection-molded on the outer periphery of the conductive component 20. When the conductive component 20 is assembled into the receiving cavity 110 from back to front, the hook portion presses forward against the rear end of the fixing member 201. Refer to Figures 6 - 8 , in addition to including the inner conductor 21 and the cable 22, the conductive component 20 further includes an outer conductor 23 and an insulator 24 located between the inner conductor 21 and the outer conductor 23. The cable 22 is electrically connected to the ends of the inner conductor 21 and the outer conductor 23. The fixing member 201 is injection-molded on the outer periphery of the outer conductor 23. Of course, in other embodiments, the fixing member 201 can also be arranged to be fixed to other parts of the conductive component 20 in other ways.

[0053] Combined with Figures 3 - 4, the fixing member 201 is provided with convex ribs 202 protruding outward from its outer periphery and grooves 203 located between the convex ribs 202. The hook portion of the elastic arm 111 passes through the corresponding groove 203 and abuts against the rear end surface of the fixing member 201. When the convex rib 202 protrudes outward, it abuts against the inner wall surface of the main housing 11 in the circumferential direction to limit the conductive component 20 in the main housing 11 in the circumferential direction. In addition, the main housing 11 includes a front blocking portion 113, and the front end of the convex rib 202 abuts against the front blocking portion 113 to limit the forward movement of the conductive component 20. In order to make the fixing of the elastic arm 111 to the conductive component 20 more stable, the number of elastic arms 111 is at least two, and they are evenly distributed along the circumference on the outer periphery of the fixing member 201. Preferably, in this embodiment, the number of elastic arms 111 is three.

[0054] Combined with Figures 2 - 3 and Figure 8 , in order to enable the fixing member 201 to be better fixed to the outer conductor 23, the outer conductor 23 includes a front portion 231 and a rear portion 232. The front end of the cable 22 is coated and electrically connected to the rear portion 232. The outer diameter of the front portion 231 is larger than that of the rear portion 232, and the fixing member 201 is formed at the junction of the front portion 231 and the rear portion 232. The conductive component 20 includes a metal sleeve 25, and the metal sleeve 25 is sleeved on the front end of the cable 22. The front end of the metal sleeve 25 abuts against the rear end of the fixing member 201. In order to make the electrical connector 100 have a better waterproof effect, the electrical connector 100 further includes a rear sealing ring 52 located in the receiving cavity 110, and the front end of the rear sealing ring 52 abuts against the rear end of the limiting member 51. The electrical connector 100 further includes a locking portion 114 provided on the main housing 11. The locking portion 114 includes an elastic holding arm 115 extending forward from the upper surface of the main housing 11 and a secondary locking member 116 movably provided on the main housing 11. A holding hole 117 is provided at the front end of the holding arm 115.

[0055] Combined with Figure 3, when the electrical connector 100 is assembled, first install the conductive component 20 into the main housing 11 from the rear end of the autonomous housing 11. To facilitate the installation of the conductive component 20, a guiding surface 1110 is provided on the hook portion of the elastic arm 111. When the conductive component 20 is installed, the elastic arm 111 expands outward under the action of the conductive component 20, that is, the elastic arm 111 deforms towards the gap between it and the main housing 11. And when the conductive component 20 is installed in place (at this time, the front end of the rib 202 of the fixing member 201 abuts against the front blocking portion 113), the elastic arm 111 elastically returns, and the hook portion of the elastic arm 111 abuts against the rear end face of the fixing member 201; install the limiting member 51 into the receiving cavity 110 from the rear end face of the main housing 11. Preferably, in this embodiment, the limiting member 51 is in a cylindrical shape. The limiting member 51 passes through the cable 22 from back to front, and its front end is inserted into the gap between the elastic arm 111 and the inner wall of the main housing 11, thereby restricting the elastic deformation of the elastic arm 111; install the rear sealing ring 52 into the main housing 11 from back to front through the cable 22 and abut against the rear end face of the limiting member 51; fix the rear end cover 12 to the main housing 11.

[0056] See Figure 1 and Figures 9 - 11 , which is basically the same as the structure of the above electrical connector 100. The docking connector 200 includes a housing 40, a conductive component 60 and a limiting member 71. The conductive component 60 includes an inner conductor 61, a cable 62, an outer conductor 63 and an insulator 64. The inner conductor 61 is a male terminal in the shape of a pin, and the cable 62 is electrically connected to the rear ends of the inner conductor 61 and the outer conductor 63. It should be particularly noted that the description of the front and rear directions in the present invention is only an illustration of a relative orientation relationship for convenience of description. And for each connector, the end where the cables 22, 62 are located is the rear end, and the mating end opposite to the end where the cables 22, 62 are located is the front end.

[0057] Continue to see Figures 9 - 10, the housing 40 includes a main housing 41 and a rear end cover 42 connected to the rear end of the main housing 41. Among them, the main housing 41 is provided with a receiving cavity 410 penetrating in the front-rear direction, and the main housing 41 is provided with a plurality of elastic arms 411 extending from front to back in the receiving cavity 410. The elastic arms 411 are provided with abutting portions 412, the conductive component 60 is provided with a fixing member 601, and the conductive component 60 is installed into the main housing 41 from the rear end of the receiving cavity 410; the abutting portion 412 of the elastic arm 411 presses forward against the fixing member 601 to initially limit the conductive component 20 provided with the fixing member 601 from moving backward. In order to make the fixing of the elastic arm 411 to the conductive component 60 more stable and reliable, the limiting member 71 is pressed into the gap between the elastic arm 411 and the inner wall of the receiving cavity 410 to limit the elastic deformation of the elastic arm 411 and prevent the abutting portion 412 from separating from the limiting member 71. Similar to the abutting portion 112 of the above electrical connector 100, the abutting portion 412 is a hook portion provided at the end of the elastic arm 411. The fixing member 601 is injection-molded on the outer periphery of the conductive component 60. When the conductive component 60 is assembled into the receiving cavity 410 from back to front, the hook portion abuts forward against the rear end of the fixing member 601, and the fixing member 601 is injection-molded on the outer periphery of the outer conductor 63. The fixing member 601 is provided with convex ribs 602 protruding outward from its outer periphery and grooves 603 located between the convex ribs 602. The hook portion of the elastic arm 411 passes through the corresponding groove 603 and presses against the rear end face of the fixing member 601. When the convex ribs 602 protrude outward, they press against the inner wall surface of the main housing 41 in the circumferential direction to limit the end conductive component 60 in the main housing 41 in the circumferential direction. In addition, the main housing 41 includes a front blocking portion (not shown in the figure), and the front end of the fixing member 601 presses against the front blocking portion to limit the forward movement of the conductive component 60.

[0058] See Figures 10 - 11 , in order to make the fixing of the elastic arm 411 to the conductive component 20 more stable, the number of elastic arms 411 is at least two, and they are evenly distributed along the circumferential direction on the outer periphery of the fixing member 601. Preferably, in this embodiment, the number of elastic arms 411 is three. In order to enable the fixing member 601 to be better fixed to the outer conductor 63, the outer conductor 63 includes a front portion 631 and a rear portion 632. The front end of the cable 62 is coated and electrically connected to the rear portion 632. The outer diameter of the front portion 631 is larger than the outer diameter of the rear portion 632, and the fixing member 601 is formed at the junction of the front portion 631 and the rear portion 632. The conductive component 60 includes a metal sleeve 65, the metal sleeve 65 is sleeved on the front end of the cable 62, and the front end of the metal sleeve 65 abuts against the rear end of the fixing member 601. The docking connector 200 further includes a rear sealing ring 72 located in the receiving cavity 410, and the front end of the rear sealing ring 72 abuts against the rear end of the limiting member 71.

[0059] Continue to see Figure 1 and 10-11. The docking connector 200 further includes a locking portion provided on the main housing 41. The locking portion includes a convex 414 protruding upward from the upper surface of the main housing 41. After the connector 100 and the docking connector 200 are docked and mated, the convex 414 enters the locking hole 117 of the locking arm 115 of the electrical connector 100, and the two connectors are docked. The pin-shaped inner conductor 61 is inserted into the inner conductor 21 having a jack to complete the electrical connection. An operation portion 118 is provided at the end of the locking arm 115 away from the locking hole 117. When the operation portion 118 is pressed, the locking arm 115 elastically deforms, and the convex 414 disengages from the locking hole 117, and the two connectors can be separated. To prevent the two connectors from being accidentally unlocked during docking, the secondary locking member 116 is operated to move below the operation portion 118 to prevent the operation portion 118 from being accidentally pressed.

[0060] See Figures 12 - 15 , which is the electrical connector of the second embodiment of the present invention. The structures of the two connectors in the first embodiment are basically the same. The electrical connector 300 includes a main housing 31, a conductive assembly (not shown in the figure), a rear seal 73, and a rear end cover 32. The conductive assembly includes an inner conductor 91, a cable 92, an outer conductor 93, and an insulator 94 located between the inner conductor 91 and the outer conductor 93. An elastic arm 311 extending from front to back is provided in the main housing 31. The elastic arm 311 is provided with an abutting portion 312. The main housing 31 is provided with a receiving cavity 310. After the conductive assembly 90 is installed into the receiving cavity 310 from back to front, the abutting portion 312 abuts against the conductive assembly forwardly in the receiving cavity 310 to prevent the conductive assembly from moving backward. In the above first embodiment, fixing members 201 and 601 are injection-molded outside the conductive assemblies 20 and 60, and the conductive assemblies 20 and 60 are abutted by abutting against the fixing members 201 and 601.

[0061] See Figures 13 - 15, in this embodiment, the conductive component is also provided with a fixing member 901. Different from the above-mentioned first embodiment, the fixing member 901 is a convex ring integrally protruding from the outer conductor 93 along its circumferential direction. The abutting portion 312 is a hook portion provided at the end of the elastic arm 311, and the hook portion abuts against the rear end of the convex ring forward. In addition, the electrical connector 300 also includes a limiting member 80. The limiting member 80 is inserted into the gap between the elastic arm 311 and the inner wall of the main housing 31 from the rear forward to prevent the elastic deformation of the elastic arm 311. When the electrical connector 300 is assembled, first, the conductive component is assembled into the receiving cavity of the main housing 31 from the rear forward. At this time, the elastic arm 311 elastically deforms outward. After the conductive component is installed in place, the elastic arm 311 elastically resets and its hook portion abuts against the rear end face of the convex ring; the limiting member 80 is passed through the cable and assembled into the main housing 31 from the rear forward; the rear end cover 32 is installed on the main housing 31. Different from the above-mentioned first embodiment, in this embodiment, the number of the elastic arms 311 is 2, and the limiting member 80 includes an annular main body portion 800 and two insertion arms 81 extending forward from the annular main body portion 800. When the limiting member 80 is installed into the main housing 31 from the rear forward, the two insertion arms 81 are respectively inserted into the gaps between the two elastic arms 311 and the main housing 31 to limit the elastic deformation of the elastic arms 311.

[0062] In the above two embodiments of the present invention, the elastic arms 111, 311, 411 are all arranged on the main housings 11, 31, 41, and the fixing members 201, 601, 43 are arranged on the conductive components 20, 60, 90. It can be understood that when the conductive components 20, 60, 90 are inserted into the main housings 11, 31, 41, the elastic arms 111, 311, 411 are restricted from deforming in the direction away from the conductive components 20, 60, 90 by inserting the limiting members 51, 71, 80. In other embodiments, the elastic arms can also be arranged on the conductive components 20, 60, 90, and the fixing members 201, 601, 43 are arranged on the main housing. For example, in other embodiments, injection molded parts are formed on the outer sides of the outer conductors 23, 63, 93 by injection molding. The injection molded parts are provided with elastic arms extending from the front to the rear on their outer circumferences, and there is a gap between the elastic arms and the outer circumferential wall of the injection molded parts. A fixing member is arranged in the main housing, and the elastic arms abut against the fixing member to restrict the backward movement of the conductive components 20, 60, 90. Specifically, if a clamping protrusion is arranged on the elastic arm and a clamping groove is arranged in the main housing, when the conductive components 20, 60, 90 are assembled into the main housings 11, 31, 41 from the rear forward, the clamping protrusion is clamped into the clamping groove to restrict the backward movement of the conductive components 20, 60, 90; after the conductive components 20, 60, 90 are installed, the limiting members 51, 71, 80 are installed into the main housings 11, 31, 41 from the rear ends of the main housings 11, 31, 41 and inserted into the gaps between the elastic arms and the outer circumferential walls of the injection molded parts to prevent the elastic arms from elastically deforming in the direction away from the fixing member.
