Description

Metal three-pawl type shielding waterproof connector

Technical field

The utility model is related to a kind of water-proof connector, more particularly to a kind of metal three-pawl type shielding waterproof connector, fits For new-energy automobile, railway transportation, instrument electronic box etc. needs to protect the field of cable.

Background technology

For present cable because new-energy automobile is the automobile of " green ", thus connector also requires that environmental protection.Nothing By be component manufacture or practice in, use green material, it is to avoid pollution, reduction energy consumption all must as producer The factor that must be considered, and these green characteristics, can also turn into the market advantage of product.

Because new-energy automobile connector highest will bear the ability of 250A electric currents, 600V voltages, high standard in terms of security Accurate electrocution-proof protection demand is obvious.Simultaneously under so high power, electromagnetic interference is another major issue. In addition, the plug operation of connector can produce electric arc, this can seriously endanger electrical connection and electronic equipment, and may cause Automobile burning, these particular designs for being required for connector and exploitation, such as will prevent high pressure air in the case of exposure Puncture, this needs to retain certain the air gap；In the case of high-voltage large current, the rise of its temperature is no more than specified Value；To consider weight, intensity and whether easy to process when selecting sheathing material, and bonder terminal at different temperatures How material property keeps stability, how to ensure that necessary conductance etc. is required for considering.

Connective aspect is increasingly dashed forward due to the continuous expansion of automotive entertainment system, the importance of high speed data transfer function Go out." such as in some vehicles, camera is mounted with reversing reflective mirror, driver can be made to possess the broader visual field, this is just Connector is needed to transmit more data.Sometimes connector is also needed to while solving transmission gps signal and broadcast singal Problem, this is accomplished by lifting its data transmission capabilities.Other aspects are generally positioned at vehicle front because of car engine, in spite of Fire wall is protected, but also has some heats and can be conducted through, therefore connector will can bear high temperature.In addition to automobile " harshness " requirement of connector was also embodied on its life-span.Have elastic component among general connector, plugging certain number of times Effect will be lost afterwards, thus the life-span is general in 3-5 or so, and an automobile can be used 10 years~20 years, therefore vapour The car connector life-span has to be equal with motor live time, and the requirement to connector is at a relatively high.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of metal three-pawl type shielding waterproof connector, installation side Just, space is greatlyd save, the axial motion of cable is effectively prevented, it is ensured that normally uses, will not produce in the case of vibrations frequently The bad problems such as raw performance failure.

The utility model is to provide a kind of metal three-pawl type shielding to solve the technical scheme that above-mentioned technical problem is used Water-proof connector, including three groups of cone seal core bodys and shell be arrangeding in parallel, during the cone seal core body and shell are in Hollow structure is simultaneously sheathed on outside cable, and the casing is outside cone seal core body, one end press-in of the cone seal core body In cross circle nut, the other end of the cone seal core body is provided with shielding spring circle and caulking gum pad, the shielding bullet Spring coil is the triangle spring circle that is sequentially connected of multiple head and the tail, and the triangle spring circle erects distribution and along cable circumferencial direction Form a circle, the setting side of the triangle spring circle is embedded into the neck on outer casing inner wall.

Above-mentioned metal three-pawl type shielding waterproof connector, wherein, the cross circle nut and shell pass through screw-threaded coupling It is connected, plane, which is affixed, on the inside of upper plane and cross the circle nut of the cone seal core body is combined.

Above-mentioned metal three-pawl type shielding waterproof connector, wherein, the interior angle of the triangle spring is circular arc chamfering.

The utility model contrast prior art has following beneficial effect：The metal three-pawl type shielding that the utility model is provided Water-proof connector, using the three groups of cone seal be arrangeding in parallel core bodys and shell, it is possible to use three-jaw spanner is once installed simultaneously Dismounting, greatlys save space；Cone seal core body and triangle spring circle are provided with per assembly housing, and is utilized respectively cross circle spiral shell Cap and outer casing inner wall neck are fixed, and effectively prevent the axial motion of cable, it is ensured that normally make in the case of vibrations frequently With the bad problem such as performance failure will not be produced.

Embodiment

The utility model will be further described with reference to the accompanying drawings and examples.

Fig. 1 is the utility model metal three-pawl type shielding waterproof connector construction schematic diagram.

Refer to Fig. 1, metal three-pawl type shielding waterproof connector that the utility model is provided, including three groups be arranged in parallel Cone seal core body 3 and shell 4, the cone seal core body 3 and shell 4 in hollow structure and are sheathed on outside cable 1, described Shell 4 is sheathed on outside cone seal core body 3, in one end press-in cross circle nut 2 of the cone seal core body 3, the taper The other end of crystal entertainment ball 3 be provided with shielding spring circle 5 and caulking gum pad 6, the shielding spring circle 5 be multiple head and the tail successively Connected triangle spring circle, the triangle spring circle, which is erect, to be distributed and is formed a circle along the circumferencial direction of cable 1, the triangle The setting side of shape turn is embedded into the neck on the inwall of shell 4.
