Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a rear-mounted floating waterproof connector. Background Art

[0002] In recent years, with the development of the new energy industry, various energy storage or mobile power products have emerged in an endless stream. Among them, stacked energy storage is one of the energy storage battery products with a relatively large proportion. Due to the small volume of the product, it is mainly used for household energy storage and has no unified installation site restrictions. Sometimes it is installed in outdoor places. Therefore, waterproof performance needs to be considered. However, the product itself is a stacked structure. Therefore, it must be able to be floatingly installed to avoid unreliable connection or even damage caused by the product's own tolerances or installation differences. Now, the requirement for the exposed part size of the product is getting smaller and smaller. Only by rear-mounting the connector can the exposed size be minimized to the greatest extent. To sum up, the connector required for current household energy storage battery products can be floating at least at one end (plug or socket), rear-mounted, and waterproof. Currently, there are basically no existing connectors on the market that can meet all the above three requirements. Therefore, there is an urgent need to design a product that meets all the characteristic requirements to meet the market needs. Summary of the Utility Model

After the socket insert core 13 is inserted into the socket front shell 11, the six buckle grooves 131 on the socket insert core 13 are correspondingly clamped with the six buckles 111 on the socket front shell 11. The first limiting surface 132 on the socket insert core 13 and the second limiting surface 112 on the socket front shell 11 are opposite left and right. The first limiting surface 132 and the second limiting surface 112 being opposite left and right means that the first limiting surface 132 contacts the second limiting surface 112, or the first limiting surface 132 and the second limiting surface 112 are correspondingly arranged left and right with a small gap, which is set according to needs. The first limiting surface 132 and the second limiting surface 112 are used to prevent the socket insert core 13 and the socket front shell 11 from loosening due to movement after being clamped.

[0032] The first sealing ring 12 is sealingly sleeved on the socket insert 13 and is in sealing contact with the front socket housing 11. Among them, the first sealing ring 12 is in an annular strip structure or an O-ring structure. In this embodiment, the first sealing ring 12 is preferably in an annular strip structure.

[0033] The periphery of the first sealing ring 12 is connected to the gasket 122 through the floating part 121. Among them, the first sealing ring 12, the floating part 121 and the gasket 122 are all made of rubber and integrally formed. The specific material thereof is any one of natural rubber, styrene-butadiene rubber, isoprene rubber, chloroprene rubber, silicone rubber, fluororubber, fluorosilicone rubber, etc. The cross section of the floating part 121 is in a V-shaped structure or a Z-shaped structure or a W-shaped structure, etc. In this embodiment, the cross section of the floating part 121 is preferably in a V-shaped structure.

[0034] The rear socket housing 14 is arranged at the rear side of the gasket 122. A first positioning and mounting post 115 is arranged at the rear side of the front socket housing 11. The gasket 122 and the rear socket housing 14 are provided with driving blocks for avoiding the first positioning and mounting post 115.

[0035] The rear housing 14 of the socket is provided with first mounting holes 141 for fixing it to the gasket 122. There are two or three or four or more first mounting holes 141. In this embodiment, it is preferably that there are four first mounting holes 141. The first mounting holes 141 are connected with fastening components 3 for fixing the rear housing 14 of the socket and the gasket 122. Among them, the first mounting holes 141 are through holes or threaded holes. In this embodiment, it is preferably that the first mounting holes 141 are threaded holes. The fastening components 3 include screws 31 and floating bushings 32. Floating through holes 113 corresponding to the first mounting holes 141 are provided on the edge part 114 of the periphery of the front housing 11 of the socket. Through holes corresponding to the first mounting holes 141 are provided on the gasket 122. The floating bushings 32 are inserted into the floating through holes 113. The length of the floating bushings 32 is greater than the thickness of the edge part 114 of the front housing 11 of the socket. A gap is maintained between the outer side wall of the floating bushing 32 and the side wall of the floating through hole 113. The gap between the outer side wall of the floating bushing 32 and the side wall of the floating through hole 113 is 1-6 mm. The gap is specifically 1 mm or 2 mm or 3 mm or 4 mm or 5 mm or 6 mm, and is set according to needs without specific limitation here. The front end of the floating bushing 32 has a frustum 321 with a diameter larger than the diameter of the floating through hole 113. The threaded part of the screw 31 passes through the floating bushing 32, the through hole on the gasket 122 and is in threaded fit with the first mounting hole 141. When the socket 1 is actually used and installed, the socket insert 13, the rear housing 14 of the socket and the gasket 122 are located inside the energy storage battery. One end of the socket insert 13 inserted into the socket passes through the through hole on the upper sheet metal 4 inside the energy storage battery box body and moves to the outside, and is clamped with the front housing 11 of the socket. The first positioning mounting posts 115 on the front housing 11 of the socket are in positioning fit with the through holes on the sheet metal 4 to achieve positioning installation. Then, the threaded part of the screw 31 passes through the floating bushing 32, the through hole on the box body sheet metal 4, the through hole on the gasket 122 and is in threaded fit with the first mounting hole 141. After the screw 31 is screwed and locked, the screw head of the screw 31 abuts against the frustum 321, the rear end of the floating bushing 32 abuts against the box body sheet metal 4, and the rear housing 14 of the socket presses the gasket 122 against the inner side wall of the sheet metal 4, so as to realize the rear installation of the socket 1. Since a gap is maintained between the outer side wall of the floating bushing 32 and the side wall of the floating through hole 113, and the length of the floating bushing 32 is greater than the thickness of the edge part 114, and the floating part 121 is made of rubber material, the front housing 11 of the socket and the socket insert 13 can move left and right and move in any direction along the circumference of the screw 31. The combined movement in two directions enables the front housing 11 of the socket and the socket insert 13 to move relative to the rear housing 14 of the socket in any direction. The moving distance can be set according to needs, so as to realize that the front housing 11 of the socket and the socket insert 13 can float relative to the rear housing 14 of the socket through the floating part 121.

[0036] The plug 2 is provided with two or three or four or more second mounting holes 21 for fixedly mounting it. In this embodiment, preferably, four second mounting holes 21 are provided. The second mounting holes 21 are through holes or threaded holes. In this embodiment, preferably, the second mounting holes 21 are threaded holes.

[0037] The plug 2 is provided with a second sealing ring 22, and a third sealing ring 23 is provided at the insertion end of the plug 2. When the plug 2 is inserted into the socket core 13, the third sealing ring 23 is in sealing contact with the inner side wall of the insertion hole of the socket core 13 to achieve sealed insertion between the two. The plug 2 is provided with a second positioning and mounting post 24. When it is necessary to fixedly connect the plug 2 to the sheet metal 4" of other energy storage batteries, first place the plug 2 inside the energy storage battery box body. One end of the plug 2 inserted into the socket 1 passes through the through hole on the sheet metal 4" and moves to the outside. The second positioning and mounting post 24 cooperates with the positioning hole on the sheet metal 4" for positioning. Then, the threaded end of the locking screw 5 passes through the through hole on the sheet metal 4" and is threadedly connected to the second mounting hole 21. By screwing the locking screw 5, the plug 2 is fixedly mounted on the sheet metal 4". At this time, the plug 2 presses the second sealing ring 22 against the sheet metal 4" to achieve sealed mounting and fixation of the plug 2.

[0038] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
