A waterproof connector 100 according to an embodiment of the present invention is described below with reference to fig. 1 to 3.

According to the present invention, the waterproof connector 100 may include: connector body 1, sealing washer 2 and flowing back groove 3. The waterproof connector 100 may be disposed on a vehicle to provide a Power supply connection for an EPS (Electric Power Steering), and may also provide a Power supply connection for other devices on the vehicle or devices on other than the vehicle, for clarity of description, the following application of the waterproof connector 100 to provide a Power supply connection for an EPS is illustrated as an example, but such illustration is not to be construed as a limitation to the scope of the present invention, and it is clearly understood by those skilled in the art that the application of the waterproof connector 100 to other devices also falls within the scope of the present invention.

As shown in fig. 1 to 3, the connector body 1 includes: public end connector 12 and female end connector 11, public end connector 12 is suitable for and female end connector 11 grafting cooperation, for the EPS provides the power supply and connects, wherein, public end connector 12 is suitable for to be connected with the EPS electricity, and female end connector 11 is suitable for to be connected with external wire 200 electricity, for the leakproofness of guaranteeing wire 200 and the 11 junctions of female end connector, be formed with mounting groove 111 on the wire connecting end of female end connector 11 being connected with wire 200 to set up sealing washer 2 in mounting groove 111, in order to realize effectual waterproof sealing effect.

But because traditional waterproof connector's sealing washer and mounting groove assembly accomplish the back, mounting groove department can have a sunk space, when female end connector arranged up, this sunk space department can store up the water droplet, and when environment temperature was lower, ponding freezes more nonvolatile, and thus the condition that leads to the terminal corrosion inside the waterproof connector just can appear the water droplet and permeate, causes waterproof connector's damage for a long time.

Therefore, the embodiment of the present invention provides a drain groove 3 on the waterproof connector 100, and the drain groove 3 is formed on the groove wall of the mounting groove 111, so that the accumulated liquid in the recess space of the mounting groove 111 can be discharged out of the waterproof connector 100, thereby avoiding damage to the waterproof connector 100.

Therefore, liquid entering the mounting groove 111 can be rapidly discharged from the liquid discharge groove 3, so that accumulated liquid is prevented from entering the waterproof connector 100, and the safety of the waterproof connector 100 is improved.

According to the utility model discloses waterproof connector 100, the liquid that gets into in this waterproof connector 100's the mounting groove 111 can be followed drain tank 3 and discharged outside waterproof connector 100 to inside avoiding liquid to enter into waterproof connector 100, and then improved waterproof connector 100's water-proof effects, guarantee its security.

In the embodiment shown in fig. 2 and 3, the highest end of the bottom wall of the liquid discharge tank 3 is not higher than the top wall of the sealing ring 2. I.e. the height of the upper surface of the sealing ring 2 is higher than or equal to the height of the lowest part of the notch of the liquid discharge groove 3. Thus, the liquid entering the mounting groove 111 can be completely discharged from the drain groove 3 to the outside of the waterproof connector 100, so that the liquid is prevented from remaining, and the protective effect can be further improved.

Preferably, the height of the upper surface of the sealing ring 2 is 1mm higher than the height of the lowest part of the notch of the liquid discharge groove 3. Therefore, on the premise of ensuring that the thickness of the sealing ring 2 is set reasonably (not too thick), all liquid entering the mounting groove 111 can be discharged.

Referring to fig. 2, the bottom wall of the drain groove 3 is formed as an inclined wall 31, and the liquid in the mounting groove 111 can be more quickly and thoroughly discharged to the outside of the waterproof connector 100 by the guiding action of the inclined wall 31. This further ensures that the accumulated liquid can be discharged quickly by providing the inclined wall 31.

Further, the upper end of the inclined wall 31 is close to the seal ring 2, and the lower end of the inclined wall 31 is far from the seal ring 2. That is, the inlet end of the inclined wall 31 is higher than the outlet end. Thereby, the liquid in the mounting groove 111 can be more rapidly discharged through the inclined wall 31 to secure the safety of the waterproof connector 100.

According to the utility model discloses a some embodiments, flowing back groove 3 is a plurality of, and the liquid in the discharge mounting groove 111 that a plurality of flowing back grooves 3 can be synchronous to improve waterproof connector 100's whole flowing back speed, with the realization in shorter time with the liquid exhaust in mounting groove 111.

As a preferred embodiment, referring to fig. 2 and 3, a total of four drainage grooves may be designed on the waterproof connector 100, and the four drainage grooves are spaced apart to drain the liquid at different positions on the mounting groove 111, so as to ensure that the liquid can be drained all around in the mounting groove 111.

Further, the plurality of liquid discharge grooves 3 are provided at equal intervals in the circumferential direction of the groove wall of the mounting groove 111. From this, not only be more convenient for set up, can make the more even that flowing back groove 3 can distribute moreover, and then can make the flowing back homoenergetic of mounting groove 111 everywhere more thorough to further improve waterproof connector 100's whole waterproof performance and security.

According to other embodiments of the present invention, the sealing ring 2 may be configured as a thick sealing ring (not shown in the figure), and the upper surface of the thick sealing ring is not lower than the upper surface of the groove wall of the mounting groove 111. That is, after the packing 2 is fitted into the fitting groove 111, the packing 2 is raised from the fitting groove 111. From this, the sunken space will not appear in the mounting groove 111, the phenomenon of hydrops also can not appear, also can effectively solve the problem that liquid enters into waterproof connector 100 in, guarantees waterproof connector 100's security.

As shown in fig. 1 and 2, the waterproof connector 100 further includes: female end protective housing 4, female end protective housing 4 cover is established on the cell wall of mounting groove 111 to make female end protective housing 4 can block up mounting groove 111. From this, can effectively guarantee the leakproofness of wire 200 and female connector 11 junction to thereby avoid liquid to enter into the inside condition that leads to the terminal corrosion of waterproof connector 100 from the junction of the two, cause the damage of waterproof connector 100, and then effectual waterproof performance and the security that has promoted waterproof connector 100.

Specifically, female end protective housing 4 forms into cap-like structure, and female end protective housing 4 has the roof and follows the rampart that roof edge downwardly extending formed promptly, has seted up the via hole on the roof to wire 200 can pass this via hole, in order not to influence the normal being connected of wire 200 and female end connector 11, the via hole department has also set up waterproof construction, for example, the sealing ring, and the rampart is suitable for the cover to establish on the lateral wall of wire link, in order to guarantee the connection effect.

According to another aspect of the present invention, the vehicle includes the waterproof connector 100 described in the above embodiments. Other configurations of the vehicle, such as transmissions, braking systems, steering systems, etc., are known in the art and well known to those skilled in the art, and therefore will not be described in detail herein.
