Abstract

The utility model discloses an audio jack, which comprises an insulating body, a plurality of connecting terminals, a waterproof sleeve body and a fixing shell. An interface is arranged on the insulating body, and the insulating body is provided with a plurality of terminal grooves communicated with the interface; the connecting terminals are inserted in the terminal grooves on the insulating body, including a butting part extending out of the insulating body; the waterproof sleeve body is covered on the insulating body, and is made of elastic material, and an annular convex edge extending out of the end surface of the insulating body; the fixing shell is arranged at the outer side of the waterproof sleeve body, and a plurality of hook holding parts are arranged on the fixing shell. In the utility model, the circuit board is hooked and held with the holding parts on the fixing shell, and the convex edge on the waterproof sleeve body is tightly squeezed on the end surface of the circuit board to cause clearance between the audio jack and the circuit board to be zero, thereby realizing the waterproof function.

Description

Audio socket

Technical field

The utility model relates to a kind of connector, particularly relates to a kind of audio socket with water-proof function.

Background technology

Along with science and technology is constantly progressive, audio socket is widely used on the electronic products such as mobile phone, digital camera.

General existing audio socket comprises an insulating body and some contact terminals that is immobilizated on the insulating body, offers a docking port on the insulating body, and contact terminal has one and reaches the outer weld part of insulating body, and weld part is in order to be welded on the circuit board.

Yet existing audio socket does not have the function design of waterproof, and moisture content or moisture can enter in the electronic product from the docking port of insulating body, thereby open circuit potential and other electronic building brick cause electronic product work quality difference or can't work at all.

The utility model content

Main purpose of the present utility model is to provide a kind of moisture content that prevents to enter into the audio socket in the electronic product at the defective that above-mentioned prior art exists.

For achieving the above object, the utility model audio socket comprises insulating body, some splicing ears, waterproof body and stationary housing.Insulating body is provided with an interface and is provided with some terminal grooves that communicate with interface; Some splicing ears are inserted in the terminal groove on the insulating body, and splicing ear comprises that contact site and that a base portion, extends from base portion reaches the abutting part outside the insulating body; The waterproof body is coated on the insulating body, and this waterproof body is made by elastomeric material, and the waterproof body is provided with one and reaches the outer annular nib of insulating body one end face; Stationary housing is installed in the external side of waterproof jacket, and stationary housing is provided with some scratching parts.

The described insulating body outside is provided with groove; Described stationary housing is provided with some card; Described waterproof body is made by silica gel, and waterproof body inboard is provided with the waterproof bulge loop, and the waterproof bulge loop holds in the groove that is contained in insulating body, and the external side of waterproof jacket is protruding some blocked blocks, and blocked block is fastened on the card.

The scratching part of described stationary housing is provided with a guide ramp.

From the above mentioned, the utility model audio socket coats a waterproof body outside insulating body, add a stationary housing in the external side of waterproof jacket, and tightly collude by the scratching part on the stationary housing and to hold circuit board, tightly be squeezed on circuit board one end face by the chimb on the waterproof body, make zero clearance between audio socket and circuit board, thereby realize water-proof function.

Embodiment

For describing technology contents of the present utility model, structural feature and purpose of being reached and effect in detail, give explanation below in conjunction with embodiment and conjunction with figs. are detailed.

See also Fig. 1, the utility model audio socket 100 comprises an insulating body 1, some splicing ears 2, a waterproof body 3 and a stationary housing 4.

Please continue to consult Fig. 1, it is rectangular-shaped that insulating body 1 roughly is, and insulating body 1 is provided with an interface 11, and on the insulating body 1 and be provided with some terminal grooves 12 that communicate with interface 11, insulating body 1 outside is provided with groove 13.

Some splicing ears 2 are inserted in the terminal groove 12 on the insulating body 1, each splicing ear 2 includes a base portion 21, one extends the contact site 22 and that forms from base portion 21 reaches abutting part 23 outside the insulating body 1, and abutting part 23 is in order to be welded on the circuit board 5.

Waterproof body 3 is to be made by the elastomeric material with water-proof function, in the utility model specific embodiment, system is made by whippy silica gel, waterproof body 3 is coated on the insulating body 1, waterproof body 1 inboard is provided with waterproof bulge loop 31, and waterproof bulge loop 31 holds in the groove 13 that is contained in insulating body 1, to reach better obturation effect and waterproof effect, waterproof body 3 outsides are protruding to be had some blocked blocks 32, waterproof body 3 to be provided with one to reach the outer annular nib 33 of insulating body 1 one end faces.

Stationary housing 4 is installed in waterproof body 3 outsides, stationary housing 4 is provided with some scratching parts 42, stationary housing 4 is provided with some card 41, each card 41 corresponds respectively to a blocked block 32, blocked block 32 is fastened on the card 41, and the scratching part 42 of stationary housing 4 is provided with a guide ramp 421.
