In addition, the character " / " in this article generally indicates that the objects associated with each other are in an "or" relationship. If the terms "first" and "second" appear, these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "multiple" appears, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0039] See Figure 1 and Figure 2As shown, an embodiment of the present application provides a connector assembly 100 that can be used for conductive connections between various devices or cables to maintain stable cable connections. At the same time, the overall structure is streamlined, the volume is small, and it is easy to install and use.

[0040] Specifically, the connector assembly 100 includes a female end connector 110 and a male end connector 120 that is plugged into and mated with the female end connector 110, wherein the female end connector 110 and the male end connector 120 are respectively installed at the ends of two cables, thereby achieving conductive connection between the cables through the plug-in mating of the female end connector 110 and the male end connector 120.

[0041] Furthermore, the female connector 110 includes a housing 111, a first sealing member 112 mounted on the outside of the housing 111, and a tail boot 115. The male connector 120 includes a locking boot 121 mounted on the end connected to the female connector 110. One end of the housing 111 is provided with external threads on the outside, and the inner side of the locking boot 121 is provided with corresponding internal threads to facilitate the assembly and disassembly of the locking boot 121 from the housing 111. The tail boot 115 is mounted on the end of the housing 111 facing away from the locking boot 121 to restrain the cable at the end of the female connector 110.

[0042] In this way, during the docking process of the female connector 110 and the male connector 120, after the female connector 110 and the male connector 120 are plugged in, the female connector 110 and the male connector 120 are further limited and fixed by rotating the locking sleeve 121 to ensure a stable connection.

[0043] Meanwhile, a mounting groove 1112 is provided on the circumference of the housing 111, and the first sealing member 112 is installed in the mounting groove 1112. When the locking sleeve 121 is locked with the housing 111, the first sealing member 112 presses against the locking sleeve 121 and the housing 111, respectively, to provide a waterproof seal for the connection gap between the female connector 110 and the male connector 120. Furthermore, the first sealing member 112 is made of a plastic material and has a certain elastic force. When the connector assembly 100 moves or is squeezed by external forces, the elastic potential energy of the first sealing member 112 can offset certain vibrations, thereby providing a shockproof effect, preventing the connector assembly 100 from loosening, and further improving the connection stability of the connector.

[0044] Continue reading Figure 3 、 Figure 4 and Figure 5 As shown, in some embodiments, the female end connector 110 further includes a first insulator 113 and a plurality of socket tubes 114. The first insulator 113 is sleeved on the inner side of the shell 111 and has a plurality of first through holes 1131 extending through the first insulator 113 along its own axial direction. Each socket tube 114 is respectively passed through a corresponding first through hole 1131.

[0045] Continue reading Figure 6 、 Figure 7 and Figure 8 As shown, the male connector 120 also includes a second insulator 122 and a plurality of pins 123. The second insulator 122 is pluggably mated with the first insulator 113, and one end of the second insulator 122 is rotatably sleeved with a locking sleeve 121. The second insulator 122 is axially penetrated by a plurality of second through-holes 1221. Each pin 123 is inserted into a corresponding second through-hole 1221 and pluggably mated with a corresponding jack tube 114.

[0046] It is understandable that the first insulator 113 and the second insulator 122 can both be made of rubber-like insulating materials, and the jack tube 114 and the pin 123 are both made of metal conductive materials to provide insulation protection for the outside of the connector assembly 100 while meeting the conductive connection of the cable.

[0047] Specifically, one of the first insulator 113 and the second insulator 122 can be provided with a plug-in slot to meet the requirements of the plug-in connection between the two. The jack tube 114 is inserted into the first through hole 1131, so that the jack tubes 114 are spaced apart by the first insulator 113 to avoid short-circuit interference between adjacent jack tubes 114. Similarly, the second insulator 122 spaces the pins 123 to avoid short-circuit interference between adjacent pins 123. The ends of the jack tubes 114 and the pins 123 that are plugged in opposite directions are both connected to cables, so that after the female connector 110 and the male connector 120 are docked, the conductive connection between the cables is achieved through the cooperation of the jack tubes 114 and the pins 123.

[0048] See again Figure 4 and Figure 7 As shown, further, a plurality of positioning grooves 1111 are provided on the inner side of the shell 111 , and a plurality of positioning keys 1222 are provided on the outer side of the second insulator 122 , and each positioning key 1222 is respectively engaged with a corresponding positioning groove 1111 .

[0049] For example, the number of positioning slots 1111 and positioning keys 1222 can be two, three, four, etc., and can be set according to actual needs. The positioning slots 1111 and positioning keys 1222 are both rectangular structures, and their length directions are parallel to the axial direction of the housing 111. In this way, during the docking process of the male connector 120 and the female connector 110, the positioning keys 1222 on the outside of the second insulator 122 can move along the positioning slots 1111, thereby limiting the position of the second insulator 122 during the docking process, ensuring the accurate docking of the second insulator 122 with the first insulator 113, and further ensuring the docking accuracy of the pin 123 and the socket tube 114.

[0050] Furthermore, the widths of the positioning slots 1111 are different, and the width of each positioning key 1222 is equal to the width of the corresponding positioning slot 1111 .

[0051] For example, there are three positioning slots 1111 and three positioning keys 1222. In a corresponding set of positioning keys 1222 and positioning slots 1111, the width of the positioning keys 1222 is the same as the width of the positioning slots 1111, ensuring proper insertion and fit between the positioning keys 1222 and the positioning slots 1111. Furthermore, by limiting the widths of different positioning slots 1111, each positioning key 1222 can only enter the positioning slot 1111 of the corresponding width, limiting the insertion position of the second insulator 122 and facilitating quick insertion of the male connector 120 and the female connector 110.

[0052] In some embodiments, a plurality of connection blocks 1132 are provided at one end where the first insulator 113 is connected to the second insulator 122 . Each connection block 1132 is provided with at least one first through hole 1131 , and grooves 1133 are provided between adjacent connection blocks 1132 so that adjacent connection blocks 1132 are spaced apart.

[0053] Correspondingly, a plurality of connecting ribs 1223 are provided on the inner side of one end where the second insulator 122 is connected to the first insulator 113. Each connecting rib 1223 and the wall surface of the second insulator 122 are enclosed to form a plurality of plug-in areas 1224. Each connecting rib 1223 is respectively passed through a corresponding groove 1133, and each connecting block 1132 is respectively plugged into and fitted with a corresponding plug-in area 1224.

[0054] Specifically, the connection end between the second insulator 122 and the first insulator 113 is a cylindrical structure with a cavity inside. Each connecting rib 1223 is disposed within the cavity and, together with the second insulator 122, forms an insertion area 1224. The shape of each insertion area 1224 corresponds to the corresponding connecting block 1132, so that when the second insulator 122 and the first insulator 113 are plugged together, each connecting block 1132 can be fully inserted into the insertion area 1224. At the same time, the connecting rib 1223 slides through each groove 1133, thereby limiting the axial rotation of the second insulator 122 by squeezing the connecting block 1132. This improves the connection strength between the male connector 120 and the female connector 110.

[0055] Furthermore, at least two connecting blocks 1132 have arcuate notches 1134 disposed on their outer sides, and an arcuate rib 1225 is disposed on the inner side of one end of the second insulator 122 where it connects to the first insulator 113. The arcuate rib 1225 and the wall surface of the second insulator 122 form a connecting portion 1226, which slides through the arcuate notch 1134.

[0056] In this embodiment, the outer sides of the two connecting blocks 1132 are provided with arc-shaped notches 1134, which are spliced ​​into a crescent shape. During the docking process between the male connector 120 and the female connector 110, the connecting portion 1226 slides along the arc-shaped notches 1134, further achieving the insertion and positioning of the second insulator 122 and the first insulator 113.

[0057] In some embodiments, the male connector 120 further includes a shielding tube 124 , which is sleeved on an end of the second insulator 122 facing away from the female connector 110 .

[0058] Specifically, the outer surface of the shielding tube 124 is coated with a shielding layer. Through the setting of the shielding tube 124, the leakage current on the surface of the electronic component can flow back to the power supply, so that other devices or instruments are not affected by the leakage current, thereby ensuring the circuit safety of the connector assembly 100.

[0059] In some embodiments, the male connector 120 further includes a second seal 125 , which is sleeved on one end where the second insulator 122 is connected to the shielding tube 124 and abuts against the second insulator 122 and the shielding tube 124 , respectively.

[0060] Specifically, the second sealing member 125 is provided at the end where the shielding tube 124 is connected to the second insulator 122, and the end of the locking ring facing away from the female end connector 110 is sleeved on the outside of the shielding tube 124, thereby further strengthening the connection strength between the shielding tube 124 and the second insulator 122, and the second sealing member 125 is used to ensure a waterproof seal between the shielding tube 124 and the second insulator 122.

[0061] In some embodiments, the male connector 120 further includes a third seal 126 , which is sleeved on one end where the second insulator 122 is connected to the first insulator 113 , and abuts against the second insulator 122 and the housing 111 , respectively.

[0062] Specifically, the third sealing member 126 is sleeved on the end of the second insulator 122, so that when the second insulator 122 is plugged into the first insulator 113, the connection gap between the second insulator 122 and the first insulator 113 is waterproofly sealed, thereby avoiding the risk of leakage of the pin 123 or the socket tube 114 due to the entry of external moisture.

[0063] It should be noted that in the embodiment of the present application, the first seal 112, the second seal 125, and the third seal 126 can all be one of the sealing workpieces such as O-rings, oil seals, etc., and are not specifically limited here, as long as the sealing assembly between the components is satisfied.

[0064] An embodiment of the present application further provides an electrical device, comprising the connector assembly 100 in any of the above embodiments.

[0065] This embodiment has the connector assembly 100 of any of the above embodiments, and therefore has all the beneficial effects of the connector assembly 100 of any of the above embodiments, which will not be described in detail here.

[0066] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0067] The above-described embodiments merely represent several implementation methods of the present application. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that a person of ordinary skill in the art may make various modifications and improvements without departing from the spirit of the present application, and these modifications and improvements fall within the scope of protection of the present application. Therefore, the scope of protection of the present patent application shall be determined by the appended claims.
