Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1 to 8, the integrated waterproof connector 100 according to an embodiment of the present utility model may be divided into two parts, namely a housing 10 fixed to a wall surface and a cover 20 fixed to the housing 10 and exposed to the wall surface, and the integrated waterproof connector 100 has a plurality of connection channels therein for placing the terminals 40. The rear end of the housing 10 is located in the wall for connecting the wiring inside the wall, and the exposed portion of the cover 20 is used for connecting the connection line outside the wall. The integral waterproof connector 100 is provided with sealing structures between the shell 10 and the wall, between the shell 10 and the cover 20 and between the cover 20 and the terminal 40, so that the performance and safety risks such as short circuit, connection failure and the like caused by water penetrating into the wall from the gaps of the integral waterproof connector 100 are avoided, and the safety is high.

Specifically, the housing 10 includes a mounting panel 12 with a plurality of mounting holes 17 formed therein, and the housing 10 can be fastened to a wall surface by bolts. A docking slot 13 is formed in the middle of the mounting panel 12, and a cover 20 is inserted into the docking slot 13 and fixed to the housing 10. The second sealing groove 14 is formed in the mounting panel 12, and a third sealing member is arranged in the second sealing groove 14, so that potential safety hazards caused by water penetrating into the wall body from a wall gap can be prevented. Preferably, the second seal groove 14 surrounds the periphery of the docking slot 13, and the corresponding third seal is an annular second seal ring 33, in such a way that the docking slot 13 can be enclosed within the waterproof area formed by the second seal ring 33.

Preferably, a plurality of protrusions are further formed on the side wall of the second sealing groove 14 to increase the roughness in the second sealing groove 14, thereby improving the fixing effect of the second sealing ring 33 and preventing the second sealing ring from being separated.

The shell 10 is provided with a plurality of first channels 11, the cover 20 is correspondingly provided with a plurality of second channels 21, and the first channels 11 and the second channels 21 are correspondingly connected one by one to form a connecting channel. As shown in fig. 8, copper bars are used as the terminals 40 in the present embodiment, which have good conductivity and can carry a relatively large current. Of course, the specific conductor may be selected according to the actual current to be carried, and the like, and the embodiment is not limited thereto.

To avoid water from penetrating through the channels in which the terminals 40 are placed, a first seal 32 is provided between the housing 10 and the cover 20. The specific structure of the first sealing member 32 is shown in fig. 7, and mainly includes a main body 321 at the bottom, a plurality of sleeves 322 extending from the main body 312, and a connecting arm 324 connecting the main body 321 and the sleeves 322. The sleeve 322 has a cross-sectional shape similar to the cross-sectional shape of the second channel 21, but is slightly larger in size. Therefore, the sleeve 322 is in interference fit with the second channel 21, so that the second channel 21 can be completely filled after being clamped in, and water is prevented from penetrating.

The first sealing member 32 is further provided with a third channel 323 for the copper bar to pass through, and the third channel 323 is located on the sleeve 322, and the cross section shape of the third channel is similar to that of the terminal 40. And the third passage 323 has an opening slightly smaller than the terminal 40 in order to prevent water from penetrating, so that the third passage 323 has an interference fit relationship therebetween, and is tightly fitted.

As shown in fig. 6, a drainage structure is further disposed on the cover 20, and includes a converging groove 24 disposed below the second channel 21, and two portions of a guiding groove 25 communicating the converging groove 24 with each second channel 21, where when water permeates through the second channel 21, water can flow into the converging groove 24 through the reversing groove 25, so as to avoid water from continuously permeating toward the rear end. Preferably, the second channel 21 has a downward inclined design at the rear end, which is more beneficial to the backflow of water seepage and can avoid water seepage from accumulating in the second channel.

The first sealing member 32 corresponds to the design of the backflow groove 25 and the confluence groove 24, and the connecting arm 324 completely covers the backflow groove 25, so that seepage can be prevented from leaking out of the confluence groove 24. And the main body 321 completely covers the confluence groove 24 to prevent the leakage of the internal water.

Preferably, a plastic coating process can be used to further improve the sealing effect. For example, the first seal member 32 is fixed to the cover 20 so that the rear end of the second passage 21 is brought into a completely airtight state, and then the terminal is inserted into the housing 322; or the terminal 40 is fixed to the first sealing member 32 using an over-molding process and then the cover 20 is mounted. The gap filling effect can be achieved by adding the plastic coating step, water is prevented from penetrating from the gap, and the waterproof effect is better.

As shown in fig. 5, a plurality of baffles 15 are provided in the docking slot 13, and the baffles 15 are provided between the adjacent first passages 11, and divide the space in the docking slot 13 into a plurality of areas, so as to prevent dangerous situations such as short circuits caused by bending and contacting of a certain terminal 40 with an adjacent terminal 40.

Preferably, each of the areas divided by the baffle 15 protrudes toward the cover 20 by a protrusion 18 which is in contact with the body 321 and has a protruding length such that the protrusion 18 pushes the body 321 of the first sealing member 32 against the cover 20 when the cover 20 is in the fixed position, thereby securing the cover to avoid unnecessary movement. The top block 18 has both a horizontal form and a vertical form in the present embodiment, and as shown in fig. 5, the top block 18 is disposed horizontally in correspondence with the channel region where the narrower terminal 40 is located; and the top block 18 is disposed vertically in the channel region corresponding to the wider terminal 40.

Further, the terminal 40 is divided into two parts with different widths, the width of the part inserted into the second channel 21 and the third channel 323 is smaller than that of the part positioned in the first channel 11, a blocking surface 41 is formed at the joint of the two parts, and the blocking surface 41 is blocked by the sleeve body 322, so that the position of the copper bar in the cover body 20 is fixed, cannot excessively move or even extend out of the cover body 20, and the safety is improved.

In the present embodiment, the sleeve 322 is extruded in the second passage 21, and it is conceivable that the sleeve 322 may be disposed toward the first passage 11, or both ends may be provided with filling and sealing structures extending into the first passage 11 and the second passage 21, to further enhance the waterproof effect.

Preferably, the cover 20 is further provided with a first seal groove 22, the first seal groove 22 is located at a side of the rear end close to the housing 10, and a first seal ring 31 (second seal member) is provided in the first seal groove 22. When the cover 20 is in the mounted position, the first seal ring 31 is pressed between the first seal groove 22 and the side wall of the docking slot 13, so that water is prevented from penetrating into the rear end of the housing 10 along the gap between the housing 10 and the cover 20.

Similarly, the first seal ring 31 may also be secured into the first seal groove 22 using an over-molding operation to enhance gap filling and waterproofing.

A plurality of fixing grooves 16 are formed in the side walls of the upper end and the lower end of the butt joint slot 13 in an array mode, and a plurality of clamping blocks 23 are correspondingly arranged at the upper end and the lower end of the cover body 20. When the clamping blocks 23 are clamped in the corresponding fixing grooves 16, the cover body 20 is fixed in place, accidental detachment of the cover body 20 can be avoided, and safety is improved. Because the rigid material is adopted, after the connector is fixed in the docking slot 13, the cover 20 cannot be taken out without damaging the fixing structure (the clamping block 23 and the fixing slot 16), so the connector in the embodiment is an integrated connector, and the cover 20 and the shell 10 are fixedly connected at one time.

In fig. 5 and 6, only the fixing groove 16 and the latch 23 are shown, it should be understood that the fixing groove 16 may be formed on any side wall of the docking slot 13, and the latch 23 may be disposed on the corresponding side of the cover 20, which is not limited in this embodiment.

In practical applications, if the specifications of the connection conductors in the connectors are identical, the maximum loadable currents are the same. When it is desired to connect connection lines with different currents, there may be situations where the maximum carrying current is exceeded. In this embodiment, therefore, a portion of the terminals 40 are wider and thicker, and can carry more current than it is. Correspondingly, the corresponding first channel 11, second channel 21 and sleeve 322 are enlarged to improve flexibility.

The first seal 32 in the integral waterproof connector 100 of the present embodiment prevents water from penetrating into the wall from the passage in which the terminal 40 is located, the first seal 31 (second seal) prevents water from penetrating into the wall from the gap between the cover 20 and the housing 10, and the second seal 33 (third seal) prevents water from penetrating into the wall from the gap between the wall and the mounting panel 12. Through multiple seal structure, improved holistic water-proof effects, guaranteed leakproofness and security.

The integral waterproof connector in this embodiment realizes the waterproof effect through setting up the sealing washer in the seal groove, in other embodiments, can directly form the sealing washer structure to the glue filling in first seal groove 22 and second seal groove 14, the adhesion effect between sealing washer and first seal groove 22 and the second seal groove 14 that this mode formed is better, and the waterproof effect is also better. It is easily conceivable that the first sealing member 32 may be omitted, and the second passage 21 may be directly filled with glue after the housing 10, the cover 20 and the terminals 40 are mounted to achieve sealing and waterproofing. The foregoing descriptions of specific exemplary embodiments of the present utility model are presented for purposes of illustration and description. It is not intended to limit the utility model to the precise form disclosed, and obviously many modifications and variations are possible in light of the above teaching. The exemplary embodiments were chosen and described in order to explain the specific principles of the utility model and its practical application to thereby enable one skilled in the art to make and utilize the utility model in various exemplary embodiments and with various modifications as are suited to the particular use contemplated.
