Abstract

A waterproof USB socket comprises an insulation base, a plurality of conductive terminals installed in the insulation base, a metal shell fixedly mounted outside the insulation base, an insulation shell formed in one piece at the periphery of the metal shell and the insulation base, and a waterproof ring sleeving at the periphery of the insulation shell. The insulation base includes a base part and a tongue plate part extending forward from the base part. A plurality of snap blocks are arranged around the base part, and slots for snapping with the snap blocks are arranged at the tail of the metal shell. The waterproof USB socket has good waterproof performance.

Description

Water proof type USB socket

Technical field

The utility model relates to a kind of electric connector, espespecially a kind of water proof type USB socket.

Background technology

Common USB connector does not generally have water-proof function, in some special applicable situations or special customer demand, requires attachment unit interface to have certain water resistance to protect under special circumstances electronic equipment not to be damaged.

Utility model content

The purpose of this utility model is to provide a kind of water proof type USB socket with good water resistance.

For this reason, the utility model provides a kind of water proof type USB socket, comprise insulating base, be installed on some conducting terminals in insulating base, be immobilizated in metal shell outside described insulating base, be shaped in the insulation crust of described metal shell and insulating base periphery and be sheathed on the water proof ring of described insulation crust periphery, the hyoplastron portion that described insulating base comprises base portion and extends to form from base portion forward direction, described base portion is provided with some fixture blocks around, and the afterbody of described metal shell is provided with the draw-in groove with described fixture block buckle.

Described conducting terminal comprises the leg that is exposed to the contact site in described hyoplastron portion and is positioned at described base portion opposite side.

The bottom punching press of described metal shell is formed with a pair of groove.

Described insulation crust rear end lower is provided with a pair of positioning support spike, and the rear end of described insulation crust is provided with smooth sheathed district.

Described water proof ring is sheathed in the sheathed district that described insulation crust is positioned at described insulation crust rear end, and described water proof ring bottom is provided with the breach that coordinates described positioning support spike.

With respect to prior art, the utility model is by metal shell and insulating base, draw-in groove being set respectively in water proof type USB socket and fixture block has strengthened steadiness and air-tightness, and sheathed water proof ring on insulation crust, is improved its water resistance simultaneously.

Embodiment

Refer to shown in Fig. 1 to Fig. 5, the utility model water proof type USB socket comprises insulating base 10, be installed on some conducting terminals 20 in insulating base 10, be immobilizated in metal shell 30 outside described insulating base 10, be shaped in the insulation crust 40 of described metal shell 30 and insulating base 10 peripheries and be sheathed on the water proof ring 50 of described insulation crust 40 peripheries.

The hyoplastron portion 12 that described insulating base 10 comprises base portion 11 and extends to form forward from base portion 11, described base portion 11 is formed with some fixture blocks 13 around.

Described conducting terminal 20 runs through described base portion 11 and extends in described hyoplastron portion 12, and described conducting terminal 20 comprises the leg 22 that is exposed to the contact site 21 in described hyoplastron portion 12 and is positioned at base portion 11 opposite sides.

Described metal shell 30 rivetings become flat tubular structure, and on the bottom 31 of described metal shell 30, punching press is downwards formed with two buckle grooves 32, and the afterbody of described metal shell 30 is provided with some draw-in grooves 33 of accommodating the fixture block 13 that holds described insulating base 10.

Described insulation crust 40 is shaped in the periphery of described metal shell 30 and described insulating base 10, and the afterbody bottom of described insulation crust 40 is provided with a pair of positioning support support part 42, and described insulation crust 40 rear ends are provided with the sheathed district 43 of round and smooth annular.

In the sheathed district 43 of annular that described water proof ring 50 is sheathed on described insulation crust 40, the bottom of described water proof ring 50 is provided with notch part 51 to coordinate the positioning support support part 42 on described insulation crust 40.

Compared to prior art, the utility model water proof type USB socket arranges respectively draw-in groove 33 and has strengthened steadiness and air-tightness with fixture block 13 on metal shell 30 and insulating base 10, and sheathed water proof ring on insulation crust 40, is improved its water resistance simultaneously.
