Background Art

[0002] For related prior art, please refer to Chinese Patent CN219892473U.

A slotted opening is provided on the housing, and the terminal position assurance member is disposed in the slotted opening and extends into the housing from the slotted opening to be clamped with the terminal assembly inside the housing. For an electrical connector with such a structure, since it is necessary to provide a slotted opening on the housing and the position of the slotted opening is located at the position where the terminal assembly is located, the sealing performance of the electrical connector is not good and the waterproof performance is poor.

[0003] Therefore, it is indeed necessary to provide an electrical connector with an improved structure to overcome the above defects.

One of the conductive component and the main housing is provided with an elastic arm, and the other of the conductive component and the main housing is provided with a fixing member. The elastic arm abuts against the fixing member to fix the conductive component in the main housing. After the conductive component is assembled into the main housing, the limiting member is inserted into the main housing from the rear to the front to abut and limit the deformation of the elastic arm in the deformation direction of the elastic arm.

[0006] Preferably, the elastic arm extends from the front to the rear in the receiving cavity of the main housing, and a hook portion is provided at the end of the elastic arm.

The number of the elastic arms is not less than two and is evenly distributed along the outer circumference of the fixing member, and the hook portions abut against the fixing member forward.

[0009] Preferably, the hook portion is provided with a guiding surface to facilitate the installation of the terminal module provided with the fixing member between the elastic arms from the rear to the front.

[0010] Preferably, the fixing member is injection-molded on the outer side of the conductive component.

[0011] Preferably, the number of the elastic arms is not less than two and they are evenly distributed in the circumferential direction. The fixing member is provided with a plurality of convex ribs protruding along its circumferential direction and grooves formed between the convex ribs.

Specific Embodiments

[0050] Please refer to Figures 1 - 4 , which is an electrical connector combination 1000 according to the first embodiment disclosed by 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 through their respective locking parts, and the specific structure will be introduced below.

[0051] See 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, and 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 the rear to the 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 a convex rib 202 protruding outward from its outer periphery and a groove 203 located between the convex ribs 202. The hook portion of the elastic arm 111 passes through the corresponding groove 203 and presses against the rear end face of the fixing member 201. When the convex rib 202 protrudes outward, it presses 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. The front end of the convex rib 202 presses against the front blocking portion 113 to limit the forward movement of the conductive component 20. 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 in the circumferential direction 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 AndFigure 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 assembly 20 includes a metal sleeve 25. The metal sleeve 25 is sleeved on the front end of the cable 22, and the front end of the metal sleeve 25 abuts against the rear end of the fixing member 201. To enable the electrical connector 100 to have a better waterproof effect, the electrical connector 100 further includes a rear sealing ring 52 located in the receiving cavity 110. 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 assembly 20 into the main housing 11 from the rear end of the main housing 11. To facilitate the installation of the conductive assembly 20, a guiding surface 1110 is provided on the hook portion of the elastic arm 111. When the conductive assembly 20 is installed, the elastic arm 111 expands outward under the action of the conductive assembly 20, that is, the elastic arm 111 deforms towards the gap between it and the main housing 11. And when the conductive assembly 20 is installed in place (at this time, the front end of the convex rib 202 of the fixing member 201 abuts against the front stop 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 the rear to the 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 by passing through the cable 22 from the rear to the front, 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-mentioned electrical connector 100. The docking connector 200 includes a housing 40, a conductive assembly 60, and a limiting member 71. The conductive assembly 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 refer to 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 and rear directions, 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 assembly 60 is provided with a fixing member 601, and the conductive assembly 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 backward movement of the conductive assembly 20 provided with the fixing member 601. In order to make the fixing of the elastic arm 411 to the conductive assembly 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-mentioned 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 assembly 60. When the conductive assembly 60 is assembled into the receiving cavity 410 from back to front, the hook portion presses forward against the rear end of the fixing member 601. 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 circumferential movement of the end conductive assembly 60 in the main housing 41. 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 assembly 60.

[0058] Refer to Figures 10 - 11, 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. 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 greater than that 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. The front end of the rear sealing ring 72 abuts against the rear end of the limiting member 71.

[0059] Continue to refer to 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. By pressing the operation portion 118, 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] Refer to Figures 12 - 15 , which is the electrical connector of the second embodiment of the present invention. It has basically the same structure as the two connectors in the first embodiment. The electrical connector 300 includes a main housing 31, a conductive component (not labeled in the figure), a rear seal 73, and a rear end cover 32. The conductive component 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. After the conductive component 90 is installed into the receiving cavity 310 from back to front, the abutting portion 312 abuts against the conductive component forward in the receiving cavity 310 to prevent the conductive component from moving backward. In the above first embodiment, fixing members 201 and 601 are injection-molded outside the conductive components 20 and 60, and the conductive components 20 and 60 are abutted by abutting against the fixing members 201 and 601.

[0061] Refer toFigures 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 forward against the rear end of the convex ring. 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 to the front to prevent the elastic deformation of the elastic arm 311. When assembling the electrical connector 300, first assemble the conductive component into the receiving cavity of the main housing 31 from the rear to the front. 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. Pass the limiting member 80 through the cable and assemble it into the main housing 31 from the rear to the front. Install the rear end cover 32 on the main housing 31. Different from the above-mentioned first embodiment, in this embodiment, the number of elastic arms 311 is 2. 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 installing the limiting member 80 into the main housing 31 from the rear to the front, 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 provided on the main housings 11, 31, 41, and the fixing members 201, 601, 43 are provided on the conductive components 20, 60, 90. It can be understood that after 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 provided on the conductive components 20, 60, 90, and the fixing members 201, 601, 43 are provided 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 provided in the main housing, and the elastic arms abut against the fixing member and restrict the backward movement of the conductive components 20, 60, 90. Specifically, if a clamping protrusion is provided on the elastic arm and a clamping groove is provided in the main housing, when the conductive components 20, 60, 90 are assembled into the main housings 11, 31, 41 from the rear to the front, the clamping protrusion is snapped 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 wall of the injection molded parts to prevent the elastic arms from elastically deforming in the direction away from the fixing member.

[0063] The above embodiments are preferred embodiments of the present invention, rather than all embodiments. Any equivalent changes made by those of ordinary skill in the art to the present invention's solutions by reading the specification of the present invention are covered by the claims of the present invention.
