Description

Technical Field

[0001] This utility model relates to the field of electrical connector technology, and more specifically, to a waterproof connection structure. Background Technology

[0002] In electronic devices, electrical connectors are typically used to achieve electrical connections between electrically independent components. Electrical connectors enable electrical conduction between two independent electrical structures. Similarly, in underwater equipment, the electrical connections between various independent waterproof components are usually made using waterproof connectors. The core function of waterproof connectors is to establish a stable electrical path through physical mating, ensuring lossless transmission of current or signals, while preventing moisture from entering the plug contact area and causing a short circuit.

[0003] However, traditional waterproof connectors mostly use threaded connections to join two parts, which is cumbersome for structures that require frequent disassembly and assembly, and therefore not very practical. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a waterproof connection structure so that the connection has the functions of easy disassembly and assembly and anti-loosening, effectively enhancing the practicality of the device.

[0005] To achieve the above objectives, this utility model provides a waterproof connection structure, including a first connector, a first connector installed on the top of the first connector, a second connector installed on the bottom of the first connector, a second connector installed on the bottom of the second connector, and two locking connection components symmetrically installed on the outer periphery of the second connector.

[0006] The second connector has two symmetrically arranged mounting slots on both sides of its top surface, and the inner bottom wall of the mounting slot is inclined outward. Two connecting seats are installed on the vertical inner wall of the mounting slot. A locking connecting component is rotatably mounted on the connecting seat in the mounting slot. The first connector has two symmetrically arranged engaging slots on its outer periphery. The locking connecting component is adapted to engage with the engaging slot. A safety buckle located below the connecting seat is horizontally installed on the inclined inner bottom wall of the mounting slot. The safety buckle is adapted to engage with the locking connecting component when the locking connecting component engages with the engaging slot.

[0007] Furthermore, the locking connection component includes a second knurled pin horizontally passing through the connecting seat, a connecting block rotatably mounted on the second knurled pin, a first knurled pin horizontally passing through the connecting block, a connecting rib plate rotatably mounted on the first knurled pin, and a locking plate fixedly mounted on the connecting rib plate; the bottom of the locking plate is provided with a safety slot, the top of the locking plate is adapted to engage with the engagement slot, and the safety buckle is adapted to engage with the safety slot.

[0008] Furthermore, the locking plate includes a vertical section and a horizontal positioning section and a horizontal safety section installed on the upper and lower sides of the vertical section. The horizontal positioning section is hook-shaped, and the safety slot is located in the horizontal safety section.

[0009] Furthermore, the waterproof connection structure also includes:

[0010] The electrical connection assembly includes two symmetrically mounted positioning protrusions on the top surface of the second connector, a plurality of pins vertically mounted inside the second connector, two symmetrically opened positioning grooves on the bottom surface of the first connector, and two sockets vertically mounted inside the first connector and corresponding to the positions of the positioning grooves. The plurality of pins are divided into two groups, and the two groups of pins correspond to the positions of the positioning protrusions respectively.

[0011] Furthermore, the positioning protrusion is annular, and the top surface of the second connector is provided with a clearance groove located inside the positioning protrusion. The pin is located in the clearance groove, the socket is located in the positioning groove, and the socket is equipped with a soldering wire socket that is compatible with the pin.

[0012] Furthermore, the waterproof connection structure also includes:

[0013] A sealing element that is fixedly installed on the outer periphery of the positioning protrusion.

[0014] Furthermore, the second connector includes a second electrical body installed at the bottom of the second connector, a second heat dissipation outer ring installed at the bottom of the second connector and located outside the second electrical body, and a second end cap fixedly installed at the bottom of the second heat dissipation outer ring, wherein the pin is electrically connected to the second electrical body.

[0015] Furthermore, the first connector includes a first electrical body mounted on the top of the first connector, a first heat dissipation outer ring mounted on the top of the first connector and located outside the first electrical body, and a first end cap fixedly mounted on the top of the first heat dissipation outer ring; the socket is electrically connected to the first electrical body.

[0016] Furthermore, a protrusion is provided on the side of the top surface of the safety buckle away from the second connector, and the width of the protrusion is smaller than the width of the safety slot. The side of the protrusion closest to the second connector is arranged vertically.

The locking plate has a square opening on the side opposite to the second connecting head, which corresponds to the position of the connecting rib and the connecting seat.

[0019] Compared with the prior art, this utility model has the following advantages and effects:

[0020] 1. In this utility model, the waterproof connection structure allows for the adjustment of the position of the locking plate on the locking connection component during the installation of the second and first connecting parts. This allows the top of the locking plate to engage with the locking groove on the first connecting head. If the locking plate is kept engaged with the first connecting head and kept horizontal, the safety buckle can also engage with the locking plate. This effectively prevents loosening while ensuring that the installation and assembly of the second and first connecting parts are simple and stable. It also avoids accidental activation that could lead to the locking mechanism being opened, greatly improving the practicality of the device.

[0021] 2. In this utility model, the waterproof connection structure can achieve precise positioning of the pin and socket by setting the positioning protrusion and positioning groove during the installation of the second connector and the first connector, which greatly improves the splicing and electrical connection efficiency of the second connector and the first connector. During this process, the sealing element set on the outer periphery of the positioning protrusion can also maintain a good waterproof sealing effect through its own elastic compression, so as to prevent water from entering the plug contact area and causing a short circuit, thus effectively improving the waterproof effect.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0042] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can also refer to the internal connection of two components; and they can refer to a wireless connection or a wired connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0043] Please see Figure 1-8 As shown, this utility model embodiment provides a waterproof connection structure, including a first connector 4, a first connector 1, a second connector 3, a second connector 2, and a locking connection component 5.

[0044] The first connector 1 is installed on the top of the first connector 4, the second connector 3 is installed on the bottom of the first connector 4, the second connector 2 is installed on the bottom of the second connector 3, and two locking connecting parts 5 are symmetrically installed on the outer periphery of the second connector 3. Two symmetrically arranged mounting grooves 36 are opened on both sides of the top surface of the second connector 3, and the inner bottom wall of the mounting groove 36 is inclined outward. Two connecting seats 31 are installed on the vertical inner wall of the mounting groove 36, and the locking connecting parts 5 are rotatably installed on the connecting seats 31 in the mounting groove 36.

[0045] Two symmetrically arranged engaging grooves 41 are provided on the outer periphery of the first connector 4. The locking connecting component 5 is adapted to engage with the engaging grooves 41. A safety buckle 32 located below the connecting seat 31 is horizontally installed on the outwardly inclined inner bottom wall of the mounting groove 36. The safety buckle 32 is adapted to engage with the locking connecting component 5 when it engages with the engaging grooves 41.

[0046] Please see Figure 1-8 As shown, the locking connecting component 5 includes a second knurled pin 54, a connecting block 55, a first knurled pin 53, a connecting rib 52, and a locking plate 51, wherein:

[0047] The second knurled pin 54 is horizontally inserted into the connecting seat 31, the connecting block 55 is rotatably mounted on the second knurled pin 54, the first knurled pin 53 is horizontally inserted into the connecting block 55, the connecting rib 52 is rotatably mounted on the first knurled pin 53, and the locking plate 51 is fixedly mounted on the connecting rib 52; the bottom of the locking plate 51 is provided with a safety slot 514, the top of the locking plate 51 is adapted to engage with the engaging groove 41, and the safety buckle 32 is adapted to engage with the safety slot 514.

[0048] As a further description of the above solution, when installing the first connector 4 and the second connector 3, the top of the locking plate 51 can be rotated to engage with the locking groove 41, and the bottom of the locking plate 51 can be pressed to make the locking plate 51 more vertical, so that the safety buckle 32 can be locked at the bottom of the locking plate 51. This keeps the installation of the locking plate 51 stable while restricting the separation of the first connector 4 and the second connector 3, thereby preventing accidental opening of the lock.

[0049] Please see Figure 1-4 and Figure 7 As shown, the locking plate 51 includes a vertical section 511 and horizontal positioning sections 512 and horizontal safety sections 513 installed on the upper and lower sides of the vertical section 511. The horizontal positioning section 512 is hook-shaped, and the safety slot 514 is located in the horizontal safety section 513. The hook-shaped horizontal positioning section 512 on the locking plate 51 can be used to lock the engaging groove 41, thereby limiting the relative movement of the first connector 4 and the second connector 3. The safety slot 514 in the horizontal safety section 513 can be used to lock the locking plate 51 by the safety buckle 32 when the vertical section 511 of the locking plate 51 is inclined to be vertical, thereby preventing the locking plate 51 from loosening.

[0050] Please see Figure 2-3 and Figure 5-7 As shown, the waterproof connection structure also includes electrical connection components:

[0051] The electrical connection assembly includes positioning protrusions 33, pins 34, positioning grooves 42, and sockets 43. Two positioning protrusions 33 are symmetrically installed on the top surface of the second connector 3. Several pins 34 are vertically installed inside the second connector 3, and the pins 34 are divided into two groups corresponding to the positions of the two positioning protrusions 33 respectively. Two positioning grooves 42 are symmetrically opened on the bottom surface of the first connector 4. Two sockets 43 are vertically installed inside the first connector 4 and correspond to the positions of the positioning grooves 42. This facilitates the precise positioning of the pins 34 and sockets 43 by utilizing the cooperation of the positioning protrusions 33 and the positioning grooves 42, so as to achieve electrical connection between the first connector 1 and the second connector 2 when the pins 34 are inserted into the sockets 43.

[0052] Please see Figure 3 and Figure 5 As shown, the positioning protrusion 33 is annular, and the top surface of the second connector 3 is provided with a relief groove located inside the positioning protrusion 33. The pin 34 is located in the relief groove, and the socket 43 is located in the positioning groove 42. The socket 43 is equipped with a soldering wire socket that is compatible with the pin 34.

[0053] As a preferred embodiment of the above solution, the number of pins 34 in this application is five, with one group of three and the other group of two. The pins 34 are pins, which facilitates the electrical connection between the first connector 1 and the second connector 2 by using the cooperation of the pins 34 with the soldering socket.

[0054] Please see Figure 3 As shown, the waterproof connection structure also includes a sealing element 35 fixedly installed on the outer periphery of the positioning protrusion 33; the sealing element 35 is an elastic material that can achieve waterproof sealing. In this application, the sealing element 35 is an example of a silicone ring, which facilitates the use of the elastic contraction of the silicone ring to achieve waterproof sealing on the outer periphery of the positioning protrusion 33 when connecting the first connector 4 and the second connector 3, thereby preventing moisture from entering the plug contact area and causing a short circuit.

[0055] Please see Figure 1-3 and Figure 7 As shown, the second connector 2 includes a second electrical body 21, a second heat dissipation outer ring 22, and a second end cap 23. The second electrical body 21 is installed at the bottom of the second connector 3, the second heat dissipation outer ring 22 is installed at the bottom of the second connector 3 and located outside the second electrical body 21, the second end cap 23 is fixedly installed at the bottom of the second heat dissipation outer ring 22, and the pin 34 is electrically connected to the second electrical body 21.

[0056] Please see Figure 5 and Figure 7 As shown, the first connector 1 includes a first electrical body 11, a first heat dissipation outer ring 12, and a first end cap 13. The first electrical body 11 is installed on the top of the first connector 4, the first heat dissipation outer ring 12 is installed on the top of the first connector 4 and located outside the first electrical body 11, the first end cap 13 is fixedly installed on the top of the first heat dissipation outer ring 12, and the socket 43 is electrically connected to the first electrical body 11.

[0057] As a further description of the above scheme, the second end cover 23 near the second electrical body 21 and the first end cover 13 near the first electrical body 11 are both provided with an electrical control module consisting of multiple battery cells and a module controller, so as to enable the various structures in the electrical equipment to work together to maintain the normal operation of the electrical equipment and monitor the status of the electrical equipment itself.

[0058] Please see Figure 7-8 As shown, a protrusion is provided on the top surface of the safety buckle 32 away from the second connector 3, and the width of the protrusion is smaller than the width of the safety slot 514. The side of the protrusion near the second connector 3 is vertically oriented. This allows the protrusion on the safety buckle 32 to fit into the safety slot 514 when the locking plate 51 is inclined to be vertical. At this time, the vertical orientation of the side of the protrusion near the second connector 3 allows the protrusion to fit tightly against the inner wall of the safety slot 514, thereby effectively restricting the movement of the locking plate 51.

[0059] As a preferred embodiment of the above solution, the safety buckle 32 is made of a material with a certain degree of elasticity, so that the safety buckle 32 can deform within a certain range with the movement of the locking plate 51 using its own elasticity. This allows the protrusion on the locking plate 51 to be easily embedded into the safety slot 514. Since the protrusion is set vertically on the side near the second connector 3, it is necessary to use a greater force to pull the locking plate 51 to remove the protrusion in the safety buckle 32 from the safety slot 514, which helps to prevent the locking plate 51 from loosening.

[0060] Please see Figure 5 As shown, the bottom surface of the first connector 4 is vertically provided with a cut surface 44 corresponding to the position of the engaging groove 41, and the edge of the engaging groove 41 near the cut surface 44 is provided with a raised edge structure; the cutting surface 44 and the raised edge structure are provided to prevent the hook-shaped horizontal positioning section 512 on the locking plate 51 from slipping out of the engaging groove 41.

[0061] Please see Figure 1-4 As shown, the connecting block 55 is in the shape of a mountain, and the spacing of the protruding parts on the connecting block 55 is larger than the width of the connecting seat 31. This allows the connecting seat 31 to be positioned within the spacing of the protruding parts on the connecting block 55, thus ensuring a stable connection between the connecting seat 31 and the connecting block 55 with the second knurled pin 54 that passes horizontally through the connecting seat 31 and the connecting block 55. The locking plate 51 has a square opening on the side opposite to the second connecting head 3, corresponding to the positions of the connecting rib plate 52 and the connecting seat 31. This square opening prevents the connecting seat 31 and the connecting block 55 from hitting the locking plate 51 when they rotate.

[0062] The working process of the above-mentioned waterproof connection structure is as follows:

[0063] The waterproof connection structure first requires that the first connector 1 and the second connector 2 be coaxial, and that the positioning protrusion 33 on the second connector 3 and the positioning groove 42 on the first connector 4 be aligned. Then the first connector 1 and the second connector 2 can be brought together until they fit tightly, so that the pin 34 can be accurately inserted into the socket 43.

[0064] At this time, by rotating the locking plate 51 on the second connector 3, the hook-shaped horizontal positioning section 512 on the locking plate 51 can be locked into the engagement groove 41 on the first connector 4. Then, by rotating the locking plate 51 to make it more vertical, the safety buckle 32 can be locked into the safety groove 514 in the horizontal safety section 513 on the locking plate 51. This allows the locking action of the safety buckle 32 and the safety groove 514 to restrict the movement of the locking plate 51, thereby preventing the locking plate 51 from loosening and detaching. This completes the assembly and splicing of the first connector 1 and the second connector 2, and effectively improves the tightness of the connection between the second connector 3 and the first connector 4.

[0065] During this process, the sealing element 35 can achieve a waterproof seal around the positioning protrusion 33 through its own elastic contraction characteristics, thereby preventing moisture from entering the plug contact area and causing a short circuit.

[0066] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this invention.
