Description

Technical Field

[0001] This utility model relates to an underwater sealed electrical connector, and more particularly to an underwater sealed electrical connector based on an elastic bonding connection. Background Technology

[0002] Electrical connectors serve to physically connect or disconnect circuits in electrical systems. To ensure the reliability of connector connections, a mechanical fixing structure is usually set between the plug and socket of the electrical connector. Common mechanical fixing structures include threaded locking structures, screw locking structures, clip locking structures, and snap-locking structures.

[0003] However, when electrical connectors are used in underwater environments, conventional mechanical fixing structures are unsuitable for the application requirements due to their cumbersome operation and susceptibility to corrosion and rust. Therefore, the plug and socket of underwater sealed electrical connectors are generally secured together with elastic straps.

[0004] Underwater sealed electrical connectors have plugs and sockets in both straight and bent configurations, such as... Figure 1 and Figure 2 The plug of the conventional underwater sealed electrical connector shown is a conventional straight plug, such as... Figure 3 and Figure 4 The plug shown is a traditional bent-type plug. Both types of plugs share the following characteristics: they include a traditional plug housing 2 and plug cables 1 and pins 3 located at both ends of the housing 2. The housing 2 is a cuboid with a significantly greater horizontal length and width than its vertical height. An insulator (not visible in the figure) is located inside the housing 2. The plug cables 1 and pins 3 are interconnected within the housing 2 and fixed by the insulator. The difference between these two types of plugs is that in the traditional straight plug, the length directions of the plug cables 1 and pins 3 are parallel, hence the name "straight." In the traditional bent-type plug, the plug cables 1 are located on the side (lower part in the figure) near the corresponding end of the housing 2, and their length directions are perpendicular to the pins 3, hence the name "bent-type." Figure 5 and Figure 6 The socket of the conventional underwater sealed electrical connector shown is a conventional straight socket, such as... Figure 7 and Figure 8The socket of the conventional underwater sealed electrical connector shown is a conventional bent socket. The similarities between these two sockets are: both include a conventional socket housing 4 and socket cables 5 and socket holes located at both ends of the conventional socket housing 4 (not visible in the figure, inside the conventional socket housing 4, their length direction is the same as the length direction of the pin 3). The conventional socket housing 4 is a cuboid shell with a lateral length and lateral width significantly greater than its vertical height. The conventional socket housing 4 contains a socket insulator (not visible in the figure). The socket cables 5 and socket holes are interconnected inside the conventional socket housing 4 and fixed by the socket insulator. The differences between these two sockets are: in the conventional straight socket, the length direction of the socket cable 5 is parallel to the length direction of the socket hole, so it is called straight. In the conventional bent socket, the socket cable 5 is located on the side (lower part in the figure) of the conventional socket housing 4 near the corresponding end, and its length direction is perpendicular to the length direction of the socket hole, so it is called bent.

[0005] In traditional underwater sealed electrical connectors, the plug and socket are fixed together by elastic straps, such as... Figure 9 As shown, the connector includes an elastic band 7 (such as an elastic rubber band) and elastic rings 6 (such as elastic rubber rings) at both ends of the elastic band 7. When connecting the plug and socket of a conventional underwater sealed electrical connector, firstly, pass both elastic rings 6 of the elastic band through the tail end of the plug cable 1 of the conventional straight plug or the tail end of the socket cable 5 of the conventional straight socket and bring them close to the conventional plug housing 2 or the conventional socket housing 4. Then, align the pin 3 with the socket. Next, pull the middle part of the elastic band 7 towards the end of the conventional bent socket or the end of the conventional bent plug, and finally place the middle part of the elastic band 7 on the outer wall of the end of the conventional bent socket or the outer wall of the end of the conventional bent plug. After completion, as shown... Figure 10 As shown in the figure, the connection structure between a traditional straight plug and a traditional right-angle socket is illustrated. The connection structure between a traditional straight socket and a traditional right-angle plug is similar.

[0006] The above-mentioned connection structure between the plug and socket of the traditional underwater sealed electrical connector has the following defects: First, the two elastic rings 6 of the elastic strap can only be inserted from the end of the plug cable 1 of the traditional straight plug or the end of the socket cable 5 of the traditional straight socket. If the plug cable 1 or the socket cable 5 is long, it is very difficult and time-consuming to insert (for example, if the cable is 1km long, the elastic ring 6 needs to go through the cable for 1km), making the operation difficult; Second, it can only be used for connection and fixation between straight structures and curved structures, and cannot be used for connection and fixation between straight structures or between curved structures, thus limiting its application; Third, the elastic band 7 is located on the vertical outer wall of the corresponding shell. Not only is it small in size, but it also lacks anti-slip and anti-detachment structures, so the elastic band 7 has a high risk of falling off. Utility Model Content

[0007] The purpose of this invention is to provide an underwater sealed electrical connector based on elastic bonding that is easy to operate, widely applicable, and not easily detached, in order to solve the above-mentioned problems.

[0008] This utility model achieves the above objectives through the following technical solutions: An underwater sealed electrical connector based on a flexible bonding connection includes a socket and a plug. The plug includes a plug housing and plug cables and pins located at both ends of the plug housing. The socket includes a socket housing and socket cables and socket holes located at both ends of the socket housing. The pins are inserted into the socket holes. Both the plug housing and the socket housing are cuboid shells with a lateral length and lateral width greater than their vertical height. The plug housing has an inwardly recessed, vertically penetrating plug groove in the middle of the outer wall near the plug cable end. The lateral width of the plug groove is greater than the diameter of the plug cable, and the plug cable passes through the middle of the plug groove. The socket housing also has an inwardly recessed... The underwater sealed electrical connector based on elastic bonding connection also includes an O-ring formed by connecting elastic bands end to end. The O-ring has through holes on its opposite side walls. The size of each through hole is not smaller than the corresponding size of the outer wall of the plug housing near the plug cable and the corresponding size of the outer wall of the socket housing near the socket cable. The O-ring is fitted onto both the upper and lower outer walls of the plug housing and the socket housing, and the plug cable and the socket cable pass through two of the through holes respectively.

[0009] Preferably, in order to achieve good elasticity, the O-ring is an elastic rubber ring.

[0010] The beneficial effects of this utility model are as follows: This invention uses an O-ring as the binding component for the plug and socket. Two through holes are provided on the O-ring, a plug groove is provided on the plug housing, and a socket groove is provided on the socket housing. In use, the two through holes of the O-ring can be directly inserted into the plug and socket housings from their closest points. After the plug and socket are properly connected, the two ends of the O-ring are stretched to the corresponding positions in the plug and socket grooves. Then, the O-ring is rotated 90° so that its two ends are respectively located within the plug and socket grooves, thus achieving a reliable binding connection between the plug and socket. The entire process does not require a cable to be threaded through the O-ring, making it easy to operate regardless of cable length, saving time and effort. It is suitable for connecting and fixing straight and bent structures, straight and straight structures, and bent and bent structures, meeting the connection and fixing requirements of all types of underwater sealed electrical connectors, significantly expanding its application range. Furthermore, because the grooves limit the movement of the O-ring, it cannot detach from the electrical connector on its own, significantly improving connection reliability.

[0012] The present invention will be further described below with reference to the accompanying drawings: like Figures 11-23As shown, the underwater sealed electrical connector based on elastic bonding connection of this utility model includes a socket, a plug, and an O-ring 12 formed by connecting the ends of an elastic band. The plug includes a plug housing 8 and plug cables 1 and pins 3 located at both ends of the plug housing 8. The socket includes a socket housing 10 and socket cables 5 located at both ends of the socket housing 10 and socket holes (not visible in the figure). The pins 3 are inserted into the socket holes. Both the plug housing 8 and the socket housing 10 are cuboid shells whose horizontal length and width are much greater than (here, "much greater than" can be understood as at least twice as large) their vertical height. The plug housing 8 has an inwardly recessed and vertically penetrating plug groove 9 on the outer wall near the plug cable 1. The horizontal width of the plug groove 9 is greater than that of the plug cable 1. The diameter plug cable 1 passes through the middle of the plug groove 9. The middle of the outer wall of the socket housing 10 near the socket cable 5 is provided with an inwardly recessed and vertically penetrating socket groove 11. The horizontal width of the socket groove 11 is greater than the diameter of the socket cable 5, and the socket cable 5 passes through the middle of the socket groove 11. The opposite side walls of the O-ring elastic ring 12 are respectively provided with elastic ring through holes 13 that are penetrating both inside and outside. The size of the elastic ring through hole 13 is not less than the corresponding size of the outer wall of the plug housing 8 near the plug cable 1 and the corresponding size of the outer wall of the socket housing 10 near the socket cable 5. The O-ring elastic ring 12 is simultaneously fitted on the upper and lower outer walls of the plug housing 8 and the upper and lower outer walls of the socket housing 10, and the plug cable 1 and the socket cable 5 respectively pass through the two elastic ring through holes 13.

[0013] Preferably, in order to achieve good elasticity, the O-ring 12 is an elastic rubber ring.

[0014] like Figures 11-23 As shown, when connecting the underwater sealed electrical connector of this utility model, the two elastic ring through holes 13 of the O-ring 12 are inserted into the end of the plug housing 8 and the socket housing 10 that are close to each other. Then, the pins 3 of the plug are aligned with the socket holes. Next, the two ends of the O-ring 12 are stretched to the corresponding positions of the plug groove 9 and the socket groove 11. Then, the O-ring 12 is rotated 90° so that the two ends of the O-ring 12 (i.e., the positions of the two elastic ring through holes 13) are respectively located in the plug groove 9 and the socket groove 11, thus achieving a reliable bonding connection between the plug and the socket. The structure after connection is as follows. Figures 20-23 As shown; the entire connection process does not require the cable to be threaded through the O-ring 12, making it easy to operate regardless of cable length, saving time and effort, and suitable for connections between straight and curved structures (such as...). Figure 22 and Figure 23 As shown), between vertical structures (such as...) Figure 20 and Figure 21 (As shown), the curved structure and the curved structure (not shown in the figure, please refer to...) Figures 20-23The structure of the connector provides a secure connection that meets the connection and fixation requirements of all types of underwater sealed electrical connectors, significantly expanding the application range. Furthermore, because the plug groove 9 and socket groove 11 limit the O-ring 12, the O-ring 12 cannot detach from the electrical connector on its own, significantly improving connection reliability.

[0015] Note: The plug housing 8 and socket housing 10 mentioned above correspond one-to-one with the conventional plug housing 2 and conventional socket housing 4 in the background art, respectively. However, because their structures have changed, different component names and marking numbers are used. The plug cable 1, pin 3, and socket cable 5 mentioned above use the same component names and marking numbers as the plug cable 1, pin 3, and socket cable 5 in the background art, since their structures do not need to change.

[0016] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
