So far, current various locking mechanisms are multifarious, and type is various for exhibition, however but without a kind of for the reliable of high current terminal
Small size locking mechanism.
It is increasingly vigorous in particular with demand of the development to high current connector of electric vehicle, to small size, low cost
The demand of connector technique be also bound to become trend, but current various locking mechanisms all cannot be satisfied these requirements.
There are two main classes for currently available technology：The first kind is with additional a snap ring or catch jacket in connector end
Achieve the purpose that clamping with the step cooperation in shell on son and make its axial restraint；Second class is to be arranged one in terminal front end
Annular groove, with the cooperation of the provided with plastic claw of connector shell front end and blocking terminal makes its axial restraint.
The first kind needs to increase extra members, increases number of parts and assembling product cost or even some card slot needs
Additional processing technology, also increases product cost and application risk；Second class needs terminal sleeve wall thickness to reach thickness could be at it
Front end recessing is undoubtedly increased its small product size, while cost can not also reduce, and clamping force often also cannot be satisfied correlation
Standard requirement.
Utility model content

The more demanding problem of part wall thickness provides a kind of terminal clamping couplings.
In order to achieve the above object, technical solution used by the utility model is：
A kind of terminal clamping couplings, including terminal and connector shell,
The connector shell includes wide chamber and narrow chamber, and the diameter of the width chamber is more than the diameter of the narrow chamber, the width
Annular transitional wall is equipped between chamber and the narrow chamber, the annular transitional wall is equipped with several cards extended towards the wide chamber
Pawl,
The terminal includes wide end and narrow end, and the diameter of the wide end is more than the diameter of said narrow end, the wide end with it is narrow
Annular groove is equipped between end,
The terminal and connector shell mating one, the clamping end of the claw is limited in the annular groove
It is interior, the terminal and the connector shell phase axial limiting.
Preferably, several described claw phase uniform intervals are set on the annular transitional wall.
Preferably, the claw of phase uniform intervals setting there are six being set on the annular transitional wall.
Preferably, the clamping end of the claw is equipped with a guide surface for terminal mating.
Preferably, the end face of the claw towards the wide chamber is plane.
Preferably, the claw is the elastic card claw for having amount of elastic deformation.
The beneficial effects of the utility model are mainly reflected in：
1. clamping between terminal and connector shell can be realized without increasing parts, clamping position is located at terminal
On, the wall thickness of connector shell is required low.
2. reducing product cost, reducing small product size and mating clamping is reliable and stable.
3. simple for structure, application easy to spread.

Specific implementation mode
The utility model provides a kind of terminal clamping couplings.Below in conjunction with attached drawing to technical solutions of the utility model into
Row detailed description, so that it is more readily understood and grasps.
A kind of terminal clamping couplings, as shown in Figure 1 to Figure 3, including terminal 1 and connector shell 2.Terminal 1 assembles
In connector shell 2.
Connector shell 2 is described, connector shell 2 includes wide chamber 21 and narrow chamber 22, and the diameter of wide chamber 21 is more than
The diameter of narrow chamber 22, is equipped with annular transitional wall 23 between wide chamber 21 and narrow chamber 22, annular transitional wall 23 is equipped with towards wide chamber 21
Several claws 3 extended.
Terminal 1 is described, terminal 1 includes wide end 11 and narrow end 12, and the diameter of wide end 11 is more than the diameter of narrow end 12,
Annular groove 4 is equipped between wide end 11 and narrow end 12.
One is coupled with connector shell 2 in terminal 1, and the clamping end 31 of claw 3 is limited in annular groove 4.
It should be noted that the connector shell 2 of this case is integrated injection molding, without other clamping parts.
Refinement description is carried out to the claw 3, the clamping end 31 of claw 3 is equipped with a guide surface 32 for the mating of terminal 1.Card
Pawl 3 towards the end face 33 of wide chamber 21 be plane.Claw 3 is the elastic card claw for having amount of elastic deformation.
The mating process and principle of this case terminal 1 and connector shell 2 are illustrated：
Direction as shown by the arrows in Figure 3 is coupled, and the narrow end 12 of terminal 1 enters the wide chamber 21 of connector shell 2, narrow
Then by claw 3, claw 3 is preferably provided with guide surface 32 at end 12, when narrow end 12 is moved towards narrow chamber 22,32 meeting of guide surface
By the active force of narrow end 12 to make claw 3 generate certain elastic deformation, after narrow end 12 enters narrow chamber 22, annular groove
4 to 3 position of claw when, 3 elastic reset of claw, clamping end 31, which is embedded in annular groove 4, realizes clamping to terminal.
In addition, for the stability of structure, annular groove 4 matches with claw 3, and annular groove 4 is embedded at clamping end 31
