Technical Field

[0002] As connector production technology matures, existing connectors can be used in different harsh environments, such as rainproof and sealed connector components that can be used in outdoor environments. Figure 1-2 As shown, the connector assembly with sealing performance in the prior art includes a plug 2 and a socket 6, the socket 6 includes a shell 61, a contact 62 and an insulator, one end of the socket 6 and the adapter plug 2 is a plug-in end, and the other end is a tail connection end. The socket 6 is provided with a socket mounting plate 18 extending in the horizontal direction near the plug-in end, the lower surface of the socket mounting plate 18 is used to contact the sealing surface of the sealing box 4 to achieve the sealing of the tail connection end, and the upper surface is provided with a guide wall 63 extending upward along the axial direction of the socket shell 61, further limiting the stability of the plug and socket when plugged. A sealing cover 3 is installed on the top of the guide wall 63 to ensure the sealing of the socket 6 when the plug and socket are completely separated. When the plug and socket need to be plugged, the sealing cover 3 needs to be manually removed, and the plug mounting plate 25 on the adapter plug 2 moves along the guide rail 5 in a preset direction to drive the plug 2 to plug with the socket 6. After the plug-in is completed and power supply and signal transmission are performed, the plug 2 and the guide rail 5 are separated with the whole device, and then the sealing cover 3 needs to be installed on the socket 6 for sealing protection. During the use of the existing socket, the sealing cover needs to be manually disassembled and installed repeatedly, which reduces the work efficiency and may also cause damage to the equipment due to the uncertainty of the manual installation state. Summary of the invention

[0003] The purpose of the present invention is to provide a socket, which solves the problem of low working efficiency caused by the sealing cover disassembly process derived from the existing socket being equipped with a sealing cover to ensure the sealing when in use.

During the process of inserting the plug into the socket, the floating insulator is pushed by the plug and moves toward the first end. When the floating insulator is at the extreme position close to the first end, the adapter contacts the fixed contact and realizes conduction between the fixed contact and the plug contact.

[0007] Furthermore, a fixed sealing ring is provided on the inner wall surface of the inner cavity of the shell near the second end, and the floating insulator is sealed and matched with the socket shell through the fixed sealing ring when the floating insulator is at the extreme position near the second end.

[0009] Furthermore, the inner wall surface of the inner cavity of the shell is a step structure near the second end and has an inner step extending inward.

Through the arrangement of the compression spring, the floating structure and the anti-slip structure, the anti-slip structure prevents the floating insulator from slipping out of the second end of the inner cavity of the shell.

The compression spring is elastically deformed under the pushing action of the plug. When the floating insulator is at the extreme position close to the first end, the adapter contacts the fixed contact and realizes conduction between the fixed contact and the plug contact. Compared with the socket in the prior art, the socket of the present invention omits the process of repeatedly disassembling and installing the sealing cover during use of the original socket, thereby improving work efficiency and reducing the uncertainty of manual installation of the sealing cover.

DETAILED DESCRIPTION

[0038] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0039] The connector assembly of the present invention is mainly aimed at connector assemblies that need to have sealing performance when used in outdoor environments, especially for plugs and sockets that are compatible with each other in the connector assembly. As mentioned in the prior art in the background technology, when the plug and socket of the existing connector assembly need to be plugged in, the socket needs to rely on the sealing cover of the plug-in section and the sealing box at the first end to ensure the sealing of both ends when it is not plugged in. When the plug and the socket are plugged in, manual intervention is required to remove the sealing cover at the first end, and then plug with the adapter plug. After the working state ends, manual intervention is required to install the sealing cover on the plug-in section of the socket again, and the above steps are repeated when it needs to be plugged in next time. Although this connector assembly can also ensure sealing performance when used, the use process is very cumbersome, time-consuming and labor-intensive, resulting in low work efficiency.

[0040] Therefore, the present invention proposes a new connector assembly, which can ensure the sealing state of the socket when it is not plugged in with the plug by setting a floating insulator in the inner cavity of the shell of the socket to block the socket connector. The floating insulator is sealed between the inner cavity of the shell at the uppermost limit position, and the plug of the connector assembly has a push end. When the plug is plugged into the socket, the push end pushes the floating insulator to the lowermost limit position, and the conductive connection of the plug and socket connector is achieved through the adapter on the floating insulator. The connector assembly of the present invention omits the sealing cover in the existing socket, and simplifies the working steps without affecting the overall sealing of the plug and socket before and after insertion.

[0041] Based on the above main concepts, embodiments are provided below for illustration.

[0042] like Figure 3-7 As shown, the connector assembly in the embodiment includes a socket 1 as shown in the figure, and the socket 1 includes a socket shell 11 with an inner cavity, and the shell inner cavity 111 has two ends. In the orientation shown in the figure, the first end is the lower end, that is, the end away from the plug, and the second end is the upper end, that is, the end close to the plug. A fixed insulator 17 is installed at the first end of the shell inner cavity 111, and a fixed contact 16 is installed in the fixed insulator 17. The fixed contact 16 can be connected to a variety of external components. For example, the side of the fixed contact 16 facing away from the shell inner cavity 111 of the socket can be connected to an external cable. The fixed contact 16 can also be used as a contact in the transfer socket to be plugged and matched with the contact of the adapter connector. The fixed contact 16 can also be used in conjunction with a printed circuit board, and the matching method includes crimping or welding with a solder hole on the printed circuit board. In order to ensure the sealing of the socket 1 after installation, an O-ring 121 is provided on the lower surface of the socket mounting plate 18 , and the O-ring 121 maintains a sealing fit between the lower surface of the socket mounting plate 18 and the upper surface of the sealing box 4 .

[0043] A floating insulator 14 is also installed in the inner cavity 111 of the shell in a movably guided manner. An adapter 13 is installed in the floating insulator 14 in a sealed manner. There are multiple ways to achieve sealed installation. In one embodiment, an adapter installation hole is provided on the floating insulator 14, and the adapter is inserted in the adapter installation hole by interference fit. An O-ring 124 is provided on each adapter 13 to ensure that the adapter 13 can be sealed with the floating insulator. The side of the adapter 13 facing away from the first end has an insertion section 131 for exposing the floating insulator 14 and plugging with the plug contact 22. A compression spring 15 is provided between the floating insulator 14 and the fixed insulator 17. The compression spring 15 provides elastic force for the floating insulator 14 to move toward the second end of the inner cavity 111 of the shell. An anti-slip structure 112 is provided on the cavity wall of the inner cavity 111 of the shell to prevent the floating insulator 14 from slipping out of the second end of the inner cavity 111 of the shell. The floating insulator 14 is sealed with the socket shell 11 at least at the extreme position close to the second end. Thus, in the natural state, that is, when the plug is in the socket, the floating insulator is pressed by the compression spring to the extreme position close to the second end, and the floating insulator is sealed with the inner cavity of the shell to achieve sealing protection for the fixed contact 16.

[0044] like Figure 8-11 As shown, the plug 2 includes a plug housing 21, in which a plug insulator 23 is fixedly installed, in which a plug contact 22 is installed, and in which a locking ring 24 is provided for locking and retaining the plug contact 22 in the axial direction during the plugging process. The plug housing 21 has a plug plugging section 211 for plugging with the socket 1, and the end of the plug plugging section 211 has a pushing end for pushing the floating insulator 14 during the plugging. The pushing end can be a protruding structure provided at the end of the plug plugging section 211, which is used to push the floating insulator 14 during the plugging. In this embodiment, the end of the plug plugging section 211 directly constitutes a pushing end to push the floating insulator 14 during the plugging. When the plug 2 is not plugged into the socket 1, the floating insulator 14 is at an extreme position close to the second end, and the adapter 13 is disengaged from the fixed contact 16. During the process of plugging the plug 2 into the socket 1, the floating insulator 14 is pushed by the pushing end and moves toward the first end. When the floating insulator 14 is at the extreme position close to the first end, the adapter 13 contacts the fixed contact 16 and realizes conduction between the fixed contact 16 and the plug contact 22.

[0045] In order to ensure that the second end of the socket 1 can always maintain sealing when the socket 1 is completely separated from the plug 2, in one embodiment, a fixed sealing ring 122 is provided on the inner wall surface near the second end in the shell inner cavity 111, and the floating insulator 14 is sealed with the socket shell 11 through the fixed sealing ring 122 when the floating insulator 14 is at the extreme position near the second end. In order to ensure that the sealing of the connector assembly can be guaranteed in three situations: when the socket 1 is completely separated from the plug 2, when the socket 1 and the plug 2 are plugged together, and when the socket 1 and the plug 2 are plugged in place, in a more preferred embodiment, the fixed sealing ring 122 has a certain length in the movable direction of the floating insulator 14, so that in the process of the plug plug section 211 pushing the floating insulator 14 to move toward the first end of the shell inner cavity 111, there is a relay sealing process with three states: the floating insulator 14 is sealed with the fixed sealing ring 122, the floating insulator 14 and the plug plug section 211 are sealed with the fixed sealing ring 122 at the same time, and the plug plug section 211 is sealed with the fixed sealing ring 122.

[0046] like Figure 12-17 As shown, when the plug 2 is plugged into the socket 1, the floating insulator 14 is pushed by the pushing end and moves toward the first end. The floating insulator 14 and the plug insertion section 211 are sealed with the inner cavity 111 of the shell through the fixed sealing ring 122. At this time, the locking ring 24 in the plug 2 limits the plug contact 22 to ensure that the plug contact 22 and the plug insulator 23 are relatively stable. After the plug contact 22 and the adapter 13 are plugged into place, the plug 2 continues to be inserted downward. The floating insulator 14 is subjected to the downward pressure given by the pushing end of the plug 2. At this time, the floating insulator 14 overcomes the elastic force of the compression spring 15 under the action of pressure and approaches the first end. In this process, the plug insertion section 211 and the floating insulator 14 gradually move downward, and the plug insertion section 211 contacts the fixed sealing ring 122 and establishes a seal with the fixed sealing ring 122. That is, at this time, the floating insulator 14 and the plug insertion section 211 are fixed. The sealing ring 122 maintains a sealed fit with the inner cavity 111 of the shell. When the plug connection section 211 and the floating insulator 14 continue to move downward, the floating insulator 14 separates from the fixed sealing ring. At this time, the plug connection section 211 replaces the floating insulator 14 and seals with the inner cavity 111 of the shell through the fixed sealing ring 122, until the floating insulator 14 is in the extreme position close to the first end, and the adapter 13 contacts the fixed contact 16 and realizes conduction between the fixed contact 16 and the plug contact 22.

[0047] An anti-detachment structure 112 is provided on the cavity wall of the shell cavity 111 to prevent the floating insulator 14 from escaping from the second end of the shell cavity 111. When the socket shell 11 is designed as a two-body with the socket mounting plate 18 as the boundary, the assembly order of the parts can be ignored. At this time, the floating insulator 14 can be installed from any end of the socket shell 11. However, considering that the two-body structure is more complicated during assembly and involves the processing cost of the parts, the socket shell 11 is made into an integrated structure in this embodiment, so the floating insulator 14 needs to be installed from the first end when assembling the socket. Therefore, considering the assembly order, the fixed insulator 17 and the socket shell 11 need to be designed to be detachable.

[0048] The anti-slip structure 112 for preventing the floating insulator 14 from slipping out of the second end of the shell cavity 111 can be arranged in a variety of ways, for example, a protrusion is arranged in the circumferential direction of the outer side of the floating insulator 14, and a vertical slide groove is arranged on the inner side of the socket shell 11, the slide groove extends upward from the lower end of the cavity wall of the shell cavity 111, and has a groove bottom facing downward, the protrusion can slide along the slide groove in the vertical direction and be blocked by the groove bottom facing downward, so that the floating insulator 14 will not slip out of the upper end of the socket shell 11. Considering the processing difficulty and the anti-slip effect, as Figure 3 As shown, in one embodiment, the inner wall surface of the shell cavity 111 is a step structure near the second end and has an inner step extending inward, and the fixed sealing ring 122 is installed on the side of the inner step facing away from the first end, and the floating insulator 14 is provided with an outer step, and the inner step constitutes the anti-slip structure 112 and blocks the outer step of the floating insulator 14.

[0049] In order to ensure the stability of the plug 2 and the socket 1 during the plugging process, ensure that the plug and socket can be plugged in a completely positive plugging relationship, such as Figure 8 As shown, in one embodiment, the end of the plug insulator 23 facing the plug 2 is provided with an insertion hole 221 at a position corresponding to each plug contact 22, and the end of the plug contact 22 facing the socket is sunk into the insertion hole 221. The insertion hole 221 allows the insertion section 131 of the adapter 13 of the socket 1 to pass through and be inserted with the plug contact 22, playing a certain insertion guide role. Correspondingly, as Figure 7 As shown, a protruding wrapping section 7 is provided at the root of the plug section 131 of each adapter 13 on the side surface of the floating insulator 14 facing the plug 2. When the plug 2 is plugged into the socket 1, the wrapping section 7 is gradually plugged into the plug hole 221 until it is completely covered by the plug hole 221.

[0050] like Figure 3As shown, in order to effectively eliminate the dielectric withstand voltage and insulation resistance failure caused by residual rainwater on the surface of the floating insulator 14, an adapter sealing structure is provided on the floating insulator 14 at the periphery of the plug section 131 of each adapter 13. When the plug and socket are plugged in, the adapter sealing structure seals with the inner wall surface of the plug hole 221 to insulate and isolate each conductive contact loop. The adapter sealing structure can be a sealing ring provided in the plug hole 221. When the plug hole 221 completely covers the wrapping section 7, the inner wall of the plug hole 221 and the outer side of the wrapping section 7 are sealed by the sealing ring. However, considering the difficulty of installation, as Figure 7 As shown, in a more preferred embodiment, the adapter sealing structure is disposed on the wrapping section 7, and specifically, the adapter sealing structure is an O-ring 123 disposed on the outer circumferential surface of the wrapping section 7. Compared with disposing the adapter sealing structure in the insertion hole 221, disposing the adapter sealing structure on the wrapping section 7 exposed to the outside is beneficial to reducing the difficulty of installation.

[0051] Considering the stability of the plug and socket during the plug-in process, and eliminating the problem of plug-in stability affecting the transmission effect of signals or current, the same as the prior art is that a guide wall 10 extending upward from the socket mounting plate 18 in the axial direction is provided at the upper end of the socket shell, and the guide wall 10 is flush with or higher than the protruding portion of the adapter 13 at the second end. Compared with the prior art, because the socket 1 provided by the present invention omits the use of the sealing cover 4, the portion of the adapter 13 protruding from the floating insulator 14 is exposed at the upper end of the socket mounting plate 18. In order to avoid water accumulation in the guide wall, a drainage port 19 is provided on the guide wall 10 arranged on the side of the socket shell 11 facing the plug 2, and the lowest point of the drainage port 19 is not higher than the side of the floating insulator 14 facing the plug 2. In order to avoid water accumulation at the second end of the shell inner cavity 111, preferably, when the floating insulator 14 is at the extreme position close to the second end, its side facing the plug 2 protrudes from the port at the second end of the shell inner cavity 111.

[0052] Considering the uniformity of the water diversion, in one embodiment, the drain outlets 19 are distributed circumferentially on the guide wall 10. In addition to ensuring that the accumulated water can be discharged normally, the position setting of the drain outlet 19 should also take into account the timeliness of the water diversion process to ensure that the diversion of the accumulated water is completed in the shortest time. In a more preferred embodiment, the drain outlet 19 is a spacing groove extending from the root of the guide wall 10 to the top.

[0053] The plug-in section 131 of the adapter 13 can be configured as a plug or a socket structure. Considering the use environment, after being configured as a socket structure, when the plug 2 is completely separated from the socket 1, water may accumulate in the socket due to weather reasons, which may affect the conduction of power or signals when plugged into the socket. Based on this, the plug-in section 131 is configured as a pin structure, and the corresponding plug contact 22 is configured as a socket structure at one end close to the plug connection section 211.

[0054] Based on the above inventive concepts or embodiments, this document also provides an embodiment of a connector assembly, such as Fig.18 As shown, unlike the above-mentioned embodiment of the connector assembly, in this embodiment, a fixed sealing ring is no longer provided at the second end of the socket, but a floating sealing ring 141 is provided on the outer peripheral surface of the floating insulator 14, and during the floating process of the floating insulator 14, the floating sealing ring 141 is always used to seal and cooperate with the inner wall surface of the shell cavity 111. Specifically, the floating sealing ring 141 is embedded in the outer step groove extending in the circumferential direction of the floating insulator 14. When the socket 1 is in a state of being completely separated from the plug 2, the floating insulator 14 is ensured to seal and cooperate with the inner wall surface of the shell cavity 111 at its first end through the floating sealing ring 141. When the plug and socket are in the process of being plugged in and in the state of being plugged in place, the plug insertion section pushes the floating insulator to move toward the first end of the shell cavity until the floating insulator 14 is in the extreme position close to the first end, and the floating insulator 14 is always used to seal and cooperate with the inner wall surface of the shell cavity 111 through the floating sealing ring 141.

[0055] The present invention further provides a plug and a socket, and the embodiments of the plug and the socket have the same structure as the plug and the socket in the above connector assembly, which will not be described in detail herein.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
