Abstract
The utility model provides a waterproof connector. The connector comprises an insulator, a conductive terminal which is arranged and fixed in an accommodating cavity of the insulator, a sealing ring and an installation nut. The insulator is provided with the accommodating cavity running from back to forth and a joint sleeve. One end of the conductive terminal is a wiring end, and the other end is a contact end. An annular groove is arranged between the wiring end and the contact end, and the sealing ring is arranged above the annular groove. The conductive terminal is fixed in the accommodating cavity of the insulator in an interference manner, and is sealed through the sealing ring. When the connector is arranged and fixed on an electric appliance device and is not in butt joint with a matched connector, a joint end is exposed in the periphery of the device. A waterproof function is realized through the sealing ring in the groove, which prevents water vapor from coming into the device.

In view of this, necessary existing known water-proof connector is carried out design improved, to overcome above-mentioned defective.
[summary of the invention]
Main purpose of the present utility model is to provide a kind of water-proof connector, by be provided with a sealing ring in conducting terminal, also can realize waterproof effect when this connector is not docked with matching connector.
The utility model above-mentioned purpose and the technical scheme of dealing with problems are achieved by as described below:
The utility model provides a kind of water-proof connector, and this connector comprises: insulator, be mounted on conducting terminal, the sealing ring in the insulator host cavity and nut is installed.The host cavity that this insulator is provided with sleeve and connects along the axis direction front and back, described conducting terminal one end is made as terminals, and the other end is contact jaw, is provided with annular groove between terminals and contact jaw, and is provided with a sealing ring thereon.
Set insulator one end is the terminal installation end, and the other end is abutting end, is provided with installation portion between the two ends, is provided with screw thread in installation portion one side, is fixed on the equipment by sealed this connector that makes of nut is installed.In locked position, folder is established a sealing ring between installation portion and apparatus casing simultaneously, forms hermetically-sealed construction.
Described insulator binding end forms sleeve, and is provided with radial direction seal ring thereon, realizes waterproof when pegging graft with the connector that docks.
Described conducting terminal forms fixed part in annular groove one side, terminal be inserted in interfere thus in the host cavity fixing.Simultaneously, terminals are provided with wiring hole, and the perpendicular screwed hole that connects that is provided with.
This connector conducting terminal interference is fixed in the insulator host cavity, realizes sealing effectiveness by set sealing ring.When this connector is mounted on the electric equipment, when not docking with matching connector, its abutting end is exposed to the equipment periphery, by the sealing ring in the groove realizing water-proof function, thereby avoid in the steam access arrangement.

[embodiment]
For ease of describing enforcement structure of the present utility model in detail, existing conjunction with figs. is in conjunction with the utility model is described as follows in detail:
As shown in Figure 1, 2, 3, a kind of water-proof connector 8 comprises: insulator 1, complex conduction terminal 2, plural sealing ring 3,5,7, terminal screw 4 and installation nut 5.
These insulator 1 one ends are installation end, one end is abutting end, is provided with a ring-type installation portion 16 between installation end and abutting end, and is provided with screw thread 11 in installation portion 16 1 sides, by nut 6 is installed this connector is fixed on the equipment (not shown) by sealed, realizes sealing effectiveness by sealing ring 5.The host cavity 13 that insulator 1 connects before and after being distributed with along axis direction, plug ccontaining for conducting terminal 2, form coupling spool 12 in the insulator abutting end, and be provided with a radial direction seal ring 7 thereon, have waterproof effect after making this connector and the connector of interworking docking.Simultaneously, between the accommodating area that the insulator installation end is provided with and host cavity 13 is penetrating 14, and to being provided with clear opening 15 in the interval, terminal 2 is inserted in the insulator containing cavity thus, is convenient to it and fixes and be connected with cable.
This conducting terminal one end is made as terminals 21, and the other end is contact jaw 22, and is provided with annular groove 23 between the two, and sealing ring 3 can be provided thereon.Form fixed part 24 in groove 23 1 sides simultaneously, be inserted in host cavity 13 for terminal 2 and interfere fixing.Terminal connections end 21 is provided with wiring hole 26, and is provided with perforation screwed hole 15 along wiring hole 26 vertical direction.These terminals 21 place between accommodating area 14, the set clear opening 15 of set screwed hole 25 and insulator installation end is corresponding, the circuit connecting wire cable can hold it by terminal screw 4 and be fixed in the terminal connections hole 26 thus, can make more firm being fixed on the insulator of this terminal simultaneously.
In addition, this embodiment also is equipped with a snap close piece 10 on insulator, and when the connector with pairing docked, snap close piece 10 was held in matching connector (not shown), can guarantee butt joint stability.
Shown in Fig. 4,5, termination contact end 22 is placed in the host cavity 13 that connects before and after the insulator, this host cavity two ends slightly larger in diameter is in the middle part diameter, this terminal is placed in by fixed part 24 interferes fixingly in the smaller cavity of diameter, its terminals 21 and contact jaw 22 set sealing rings 3 also are arranged in wherein in the lump.When this connector is installed on the apparatus casing 10, interact by the sealed and edge body installation portion 16 that nut 6 is installed, make firm being fixed on the apparatus casing 10 of this connector, sealing ring 5 is located between housing 10 and the installation portion 16, makes this place's mounting structure realize sealing.Cable 9 is inserted in the set wiring hole 26 of terminal connections end 12, and it is sealed fixing with it to pass insulator clear opening 15 by terminal screw 4, and the device interior circuit connects (also can carry out circuit with the terminal welding by cable and be connected, not as limitting).And this connector coupling spool 12 is exposed to apparatus casing 10 peripheries, also can realize sealing effectiveness when not docking with matching connector, and steam is access arrangement inside thus.
