Description

Technical Field

[0001] The invention relates to the technical field of conductive connection devices, in particular to a modular detachable watertight connector. Background Art

[0002] Watertight connectors are mainly used for communication or power transmission between the inside of the underwater equipment cabin and the outside. Generally, watertight sockets are sealed and installed on the underwater equipment panel. The inside is a dry cabin environment and the outside is a wet cabin environment. Watertight plugs are mostly used in the water outside the cabin, or for connection between underwater cables. The tail cable is sealed with a vulcanized rubber sleeve. Watertight connectors usually need to have transverse sealing and longitudinal sealing functions.

[0003] In order to ensure the internal sealing effect of existing watertight connectors, most of the internal structures of watertight connectors are integrally molded to ensure a closed space and thus maintain the sealing effect. However, once a part of the one-piece molded structure leaks or is damaged, the entire structure must be replaced. This is inconvenient to use and maintain, has poor flexibility, high repair and maintenance costs, and poor emergency repair capabilities in the event of a failure. Moreover, the sealing effect of the one-piece molded structure is only achieved by its own material and structure.

[0004] Therefore, it is necessary to provide a modular detachable watertight connector to solve the above technical problems. Summary of the invention

[0005] The purpose of the present invention is to provide a modular detachable watertight connector to solve the problems existing in the above-mentioned background technology. The technical solution of the present invention aims at the technical problem that the existing technical solution is too single, and provides a solution that is significantly different from the existing technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular detachable watertight connector, comprising a shell 1 and a shell 2 connected to the shell 1, a connecting seat 1 is installed inside the shell 1, a connecting seat 2 matching with the connecting seat 1 is installed inside the shell 2, a rubber part 1 is installed on the inner side of the connecting seat 1, a contact part 1 passing through both ends is installed inside the rubber part 1, a rubber part 2 is installed on the inner side of the connecting seat 2, a contact part 2 passing through both ends is installed inside the rubber part 2, and the outer walls of the contact part 1 and the contact part 2 are provided with fixed protective parts.

[0007] Preferably, a positioning groove is provided on the inner side of the connecting seat 1, a limiting block matching with the positioning groove is installed on the outer wall of the connecting seat 2, and a sealing threaded seat is threadedly connected to the outer wall of the outer shell 2.

[0008] Preferably, a head-end socket is installed at one end of the shell 1 away from the shell 2, and a plug-in socket 1 is provided at one end of the head-end socket facing the shell 1 to form a plug-in structure with the shell 1.

[0009] Preferably, a tail end interface socket is installed at one end of the shell 2 away from the shell 1, and a plug socket 2 is provided at one end of the tail end interface socket facing the shell 2 to form a plug-in structure with the shell 2.

[0010] Preferably, a first through hole for accommodating the contact piece 1 is opened inside the rubber piece 1, and the contact piece 1 is fitted with the first through hole.

[0011] Preferably, a second through hole for accommodating the second contact piece is provided inside the second rubber piece, and a diameter of the second through hole is slightly larger than a diameter of the second contact piece.

[0012] Preferably, the fixed protective member has a first opening at one end facing the first shell and matched with one end of the contact member, and the fixed protective member has a second opening at one end facing the second shell and slightly larger than the second end of the contact member, and the first opening is connected to the second opening.

[0013] Preferably, the outer wall of the contact member 1 that does not extend out of the rubber member 1 is provided with protrusions 1 at equal intervals.

[0014] Preferably, protrusions 2 are equidistantly arranged on the outer wall of one end of the contact member 2 extending out of the rubber member 2.

[0015] Preferably, a sealing gasket is provided in an annular shape on the outer wall of the fixed protective member.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The first through hole provided in the present invention is in close contact with the contact piece 1 so that the inside of the first through hole is blocked, thereby ensuring the sealing effect of the rubber piece 1. Moreover, in the working environment, the watertight connector is located deep underwater, and the external pressure is relatively high. Even if the external water penetrates into the inside of the housing 1 and the housing 2, the pressure of the deep sea water will act on the outside of the rubber piece 1. Since the rubber piece 1 is made of an elastic material, the pressure of the deep sea water on the outside of the rubber piece 1 will cause the rubber piece 1 to shrink and deform in the direction of the central axis of the rubber piece 1, thereby making the rubber piece 1 and the contact piece 1 squeeze tighter and achieving a better sealing effect. The diameter of the second through hole provided in the present invention is slightly larger than the diameter of the second contact piece, so that the second contact piece can have adjustment space in a certain area when inserted into the second through hole, which facilitates the insertion of the first contact piece into the second contact piece, can cope with errors generated in the manufacturing process and errors generated in the assembly process, greatly reduces the unqualified rate of components, and once the second contact piece or the first contact piece is damaged, it can be replaced separately, and the maintainability is higher; The first opening provided in the present invention allows the needle end of contact piece one to be inserted, and the second opening provided allows the connecting end of contact piece two to be inserted. Due to the movable adjustment between contact piece two and the second through hole, the axis of the second opening can have a certain adjustment ability relative to the second through hole, and when the needle of contact piece one is inserted into the inner side of the connecting end of contact piece two, the contact piece two can be automatically adjusted and aligned, and the effect of strong self-adaptation can be achieved, so that contact piece two can adapt to the activity space within a certain range generated during the production process of preparing contact piece one, and once the number of contact pieces one used increases, the technical advantage is more prominent. As the number of connections between contact piece one and contact piece two increases, the possibility of errors in the preparation of contact piece one and contact piece two is greater. By adjusting contact piece two within a certain range inside rubber piece two, errors to a certain extent can be avoided, and the application effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

The following is an explanation of an embodiment of the present invention based on the overall structure of the present invention.

[0021] See also Figure 1-7 A modular detachable watertight connector comprises a shell 1 and a shell 2 connected to the shell 1, a connecting seat 3 is installed inside the shell 1, a connecting seat 4 matching the connecting seat 3 is installed inside the shell 2, a rubber member 5 is installed on the inner side of the connecting seat 3, a contact member 6 passing through both ends is installed inside the rubber member 5, a rubber member 27 is installed on the inner side of the connecting seat 4, a contact member 28 passing through both ends is installed inside the rubber member 27, and a fixed protective member 9 is provided on the outer walls of the contact member 6 and the contact member 28.

[0022] like Figure 1-7 As shown, a positioning groove 10 is provided on the inner side of the connecting seat 1 3, a limiting block 11 matching the positioning groove 10 is installed on the outer wall of the connecting seat 2 4, and a sealing threaded seat 12 is threadedly connected to the outer wall of the outer shell 2. The positioning groove 10 provided on the inner side of the connecting seat 1 3 allows the limiting block 11 installed on the outer wall of the connecting seat 2 4 to be positioned at a corresponding position, so that the connecting seat 2 4 is inserted into the inner side of the connecting seat 1 3, and then the outer shell 1 2 is connected, and then the outer shell 1 2 is locked by the provided sealing threaded seat 12.

[0023] like Figure 1-7 As shown, a head-end socket 13 is installed at one end of the shell 1 away from the shell 2 2, and a plug-in seat 14 is provided at one end of the head-end socket 13 facing the shell 1 to form a plug-in structure with the shell 1. The provided plug-in seat 14 enables the head-end socket 13 and the shell 1 to form a detachable plug-in structure.

[0024] like Figure 1-7 As shown, a tail end interface socket 15 is installed at one end of the shell 2 away from the shell 1, and a plug-in seat 2 16 is provided at one end of the tail end interface socket 15 facing the shell 2 to form a plug-in structure with the shell 2. The provided plug-in seat 2 16 enables the tail end interface socket 15 and the shell 2 to form a detachable plug-in structure.

[0025] like Figure 1-7 As shown, a first through hole for accommodating the contact piece 6 is provided inside the rubber piece 5, and the contact piece 6 is fitted with the first through hole. The first through hole is fitted with the contact piece 6 so that the inside of the first through hole is blocked. The rubber piece 5 can be configured to be vulcanized into one with the contact piece 6 to seal the outside of the contact piece 6 to ensure the sealing effect of the rubber piece 5. In addition, under the working environment, the watertight connector is located deep underwater and the external pressure is relatively high. Even if the external water penetrates into the inside of the housing 1 and the housing 2, the pressure of the deep sea water will act on the outside of the rubber piece 5. Since the rubber piece 5 is made of an elastic material, the pressure of the deep sea water on the outside of the rubber piece 5 will cause the rubber piece 5 to shrink and deform in the direction of the central axis of the rubber piece 5, thereby making the rubber piece 5 and the contact piece 6 squeezed tighter and achieving a better sealing effect.

[0026] like Figure 1-7 As shown, a second through hole for accommodating contact piece 28 is opened inside rubber piece 27, and the diameter of the second through hole is slightly larger than the diameter of contact piece 28. The second through hole diameter is set slightly larger than the diameter of contact piece 28 so that contact piece 28 can swing within a certain area when inserted into the second through hole, which facilitates the insertion of contact piece 16 into the interior of contact 2, can cope with errors generated in the manufacturing process and errors generated in the assembly process, greatly reduces the unqualified rate of components, and once contact piece 28 or contact piece 16 is damaged, they can be replaced separately, which is more maintainable.

[0027] like Figure 1-7As shown, the fixed protective member 9 is provided with a first opening 17 that matches the end of the contact member 6 at one end facing the housing 1, and a second opening 18 that is slightly larger than the end of the contact member 8 at one end facing the housing 2, and the first opening 17 is communicated with the second opening 18. The first opening 17 is provided so that the needle end of the contact member 6 can be inserted, and the second opening 18 is provided so that the connecting end of the contact member 8 can be inserted. Due to the movable adjustment between the contact member 8 and the second through hole, the axis of the second opening 18 can have a certain error relative to the second through hole, and When the needle of contact piece 1 6 is inserted into the inner side of the connecting end of contact piece 2 8 , automatic correction of contact piece 2 8 can be realized, so that contact piece 2 8 can adapt to the error within a certain range generated in the production process of contact piece 1 6 . Moreover, once the number of contact pieces 1 6 used increases, the technical advantage is more prominent. As the number of connections between contact piece 1 6 and contact piece 2 8 increases, the possibility of errors in the preparation of contact piece 1 6 and contact piece 2 is greater. By adjusting contact piece 2 8 within a certain range inside rubber piece 2 7 , errors to a certain extent can be avoided, and the application effect is better.

[0028] like Figure 1-7 As shown, the outer wall of the contact member 6 that does not extend out of the rubber member 5 is equidistantly provided with protrusions 19, and the protrusions 19 are provided to seal the through holes opened inside the rubber member 5, thereby achieving a sealing effect, and there is a certain gap between the protrusions 19, so that material can be added later to enhance the sealing effect.

[0029] like Figure 1-7 As shown, the outer wall of one end of the contact member 2 8 extending out of the rubber member 2 7 is equidistantly provided with protrusions 20, and the protrusions 20 are provided to seal the through holes opened inside the rubber member 2 7, thereby achieving a sealing effect, and there is a certain gap between the protrusions 20, so that material can be added later to enhance the sealing effect.

[0030] like Figure 1-7 As shown, a sealing gasket 21 is provided in an annular shape on the outer wall of the fixed protective member 9. The sealing gasket 21 has a certain limiting function when the contact members 1 6 and 2 8 are inserted into the interior of the fixed protective member 9, thereby avoiding the possibility that the first opening 17 and the second opening 18 will become excessively enlarged during the insertion of the contact members 1 6 and 2 8 into the fixed protective member 9.

[0031] Working principle: When in use, the positioning groove 10 set on the inner side of the connecting seat 13 allows the limit block 11 installed on the outer wall of the connecting seat 24 to be positioned at the corresponding position, so that the connecting seat 24 is inserted into the inner side of the connecting seat 13, and then the shell 1 and the shell 22 are connected, and then the shell 1 and the shell 22 are locked by the set sealing thread seat 12, the set plug-in seat 14 allows the head end socket 13 and the shell 1 to form a detachable plug-in structure, the set plug-in seat 2 16 allows the tail end interface socket 15 and the shell 22 to form a detachable plug-in structure, the opened first through hole is in contact with the contact piece 16 so that the inside of the first through hole is blocked, and the connection is secure. In order to ensure the sealing effect of the rubber part 5, and in the working environment, the watertight connector is located deep underwater, and the external pressure is relatively high. Even if the external water penetrates into the inside of the outer shell 1 and the outer shell 2, the pressure of the deep sea water will act on the outside of the rubber part 5. Since the rubber part 5 is made of elastic material, the pressure of the deep sea water on the outside of the rubber part 5 will cause the rubber part 5 to shrink and deform toward the central axis of the rubber part 5, so that the rubber part 5 and the contact part 6 are squeezed tighter, so that the sealing effect is better. Similarly, the rubber part 27 and the contact part 28 are squeezed tighter, so that the sealing effect is better. The second passage is set The hole diameter is slightly larger than the diameter of the contact piece 2 8 so that the contact piece 2 8 can shake in a certain area when inserted into the second through hole, which is convenient for the contact piece 1 6 to be inserted into the interior of the contact piece 2, and can cope with the errors generated in the manufacturing process and the errors generated in the assembly process, greatly reducing the unqualified rate of the parts, and once the contact piece 2 8 or the contact piece 1 6 is damaged, it can be replaced separately, and the maintainability is higher. The first opening 17 is set to allow the needle end of the contact piece 1 6 to be inserted, and the second opening 18 is set to allow the connecting end of the contact piece 2 8 to be inserted. Due to the movable adjustment between the contact piece 2 8 and the second through hole, the second opening The axis of 18 can have a certain error relative to the second through hole, and when the needle of contact piece 1 6 is inserted into the inner side of the connecting end of contact piece 2 8, automatic correction of contact piece 2 8 can be realized, so that contact piece 2 8 can adapt to the error within a certain range generated in the production process of contact piece 1 6, and once the number of contact pieces 1 6 used increases, the technical advantage is more prominent. As the number of connections between contact piece 1 6 and contact piece 2 8 increases, the possibility of errors in the preparation of contact piece 1 6 and contact piece 2 is greater. By adjusting contact piece 2 8 within a certain range inside rubber piece 2 7, errors to a certain extent can be avoided, and the application effect is better.
