Description
Technical field
The utility model relates to a kind of water-proof connector.
Background technology
The main function of water-proof connector is to make circuits such as conductor wire, holding wire to realize the electrical connection of waterproof, the connecting portion of guaranteeing circuit is isolated from the outside, be not subjected to the influence of extraneous moisture, thereby circuit also can normally be used under the environment of humidity, be applied in the gasoline power assist vehicle usually and be connected with electrical equipment on the vehicles such as storage battery power assist vehicle.Therefore, the quality of its water resistance directly affects the height of water-proof connector quality.ZL 200820162610.1 discloses a kind of water-proof connector, this water-proof connector is the interference fit between the fitting projection of the chimeric recess by socket and plug mainly, and on the outer peripheral face of the inner peripheral surface of chimeric recess and fitting projection can be chimeric mutually annular recess and the annular projection purpose that realizes waterproof.The shortcoming of this waterproof construction is the influence that expanded with heat and contract with cold by member, so water-proofing time is shorter; In addition, in case plug or socket damage, lose water resistance, must all change together, replacement cost is higher.
Summary of the invention
The technical problems to be solved in the utility model is to provide the water-proof connector that a kind of water resistance is better, replacement cost is low.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of water-proof connector, form by plug that is provided with contact pin and the socket butt joint that is provided with the jack that can insert contact pin, wherein plug ends is the fitting projection of docking with the chimeric cavity of socket, contact pin is installed on the end face of fitting projection, jack is located in the chimeric cavity, it is characterized in that: a sealing ring is installed on the described fitting projection, sealing circle and described chimeric cavity are interference fit, on plug, be with a nut, on the outer peripheral face of the end of socket, be processed with the screw thread that cooperatively interacts with nut.
On the end face of described fitting projection, the periphery of contact pin also is provided with a contact pin shielded metal tube; Inner peripheral surface at described chimeric cavity is provided with the jack shielded metal tube chimeric with contact pin shielded metal tube.
In the jack of described socket, be provided with and be used for the metal terminal that is connected with contact pin.
The shell of described plug and socket all adopts the flexible PVC injection molded.
The above-mentioned contact pin and the material of metal terminal are brass or phosphor-copper.
The beneficial effects of the utility model are: owing to utilize interference fit between sealing ring and the socket and nut that this mode that cooperates further locking is reached the purpose of waterproof, therefore the water resistance of this structure is better, longer service life; And after the water resistance reduction, only need to change sealing ring, plug and socket all need not be changed, thereby saved replacement cost;

Embodiment
Below in conjunction with accompanying drawing preferred implementation of the present utility model is explained in detail:
The utility model relates to a kind of water-proof connector, it can make multicore water-proof connectors such as two cores, three cores, four-core, be that example is described the utility model with eight cores below: as shown in figures 1 and 3, it is made up of plug 1 that is provided with contact pin 11 and socket 2 butt joints that are provided with the jack 21 that can insert contact pin 1.Wherein the shell of plug 1 and socket 2 all adopts the flexible PVC injection molded, and plug 1 end is the fitting projection 12 of docking with the chimeric cavity 22 of socket 2.End face in fitting projection 12 is provided with eight contact pins 11, it stretches out the end face certain-length of fitting projection 12, as shown in Figure 2, these eight contact pins are made up of three power pins 111 and five signal pin 112, and they weld with three power lines and five holding wires respectively in plug 1 inside.On the end face of fitting projection 12, the periphery of eight contact pins is provided with a contact pin shielded metal tube 13; this contact pin shielded metal tube 13 can shield to the contact pin that stretches out the fitting projection end face on the one hand; can match with the jack shielded metal tube 24 in the chimeric cavity 22 on the other hand; plug 1 and socket 2 can be plugged on together better more easily; in addition; contact pin shielded metal tube 13 and jack shielded metal tube 24 are plugged on can also shield extraneous interference signal together, guarantees that the transmission of signal in the water-proof connector is not subjected to extraneous interference.One sealing ring 3 also is installed on fitting projection 12, sealing circle and chimeric cavity 22 are interference fit, on plug 1, be with a nut 4, this nut is realized the extruding to sealing ring 3 by matching with screw thread 23 on socket 2 outer peripheral faces, thereby can reach better waterproof effect so that the connection of plug and socket is more tight.In chimeric cavity 22, be processed with eight jacks 21 with eight contact pin corresponding sections, in these eight jacks, be provided with the metal terminal 25 that is connected with above-mentioned eight contact pins, these eight metal terminals are made up of three power supply terminals 251 and five signal terminals 252, and they weld with three power lines and five holding wires respectively in socket 2 inside.
The quantity of contact pin in the utility model and the metal terminal that matches with contact pin and material can require change according to reality, thereby can make use occasion of the present utility model and anti-rush of current ability is also corresponding changes.For example contact pin in the utility model and metal terminal are made as adopting phosphor-copper, then can significantly improve anti-rush of current ability of the present utility model.Therefore, every foundation technical spirit of the present utility model is done any simple modification, equivalent variations and modification to above-mentioned execution mode, all still belongs in the scope of technical solutions of the utility model.
