Abstract
The utility model relates to a single-core large-current electric connector. The electric connector comprises a shell and a contact element assembled in the shell through an insulator. An outer peripheral surface of a tail end of the insulator is provided with a bump. A clamping hole, which corresponds to the bump, is arranged on a circumferential shell wall of the shell. The bump is firmly installed and clamped in the corresponding clamping hole. According to the single-core large-current electric connector of the utility model, because the bump is arranged on the insulator, the clamping hole which corresponds to the bump is arranged on a circumferential shell wall of the shell and the bump is firmly installed and clamped in the corresponding clamping hole, parts of a jump ring and the like are not needed to fix the insulator. Therefore, an axial dimension of the shell can be correspondingly shortened. When the electric connector is designed, only a following condition needs to be satisfied: the insulator needs to satisfy a demand of a creepage distance of corresponding power. A whole size of the electric connector can be reduced so as to satisfy a usage requirement of occasions with small space and large power. A problem that the current electric connector is not suitable for being used in the occasions with the small space and the large power is solved.
Description
Technical field
The utility model relates to and is electrically connected annex, especially a kind of single core large-current electric connector.
Background technology
Electric connector has obtained using very widely in being electrically connected with its quick and easy characteristic.At present, in short supply day by day along with non-renewable energy resources, the development of electric automobile is brought into schedule by people gradually, and electric connector then becomes the vitals that is electrically connected that is used for realizing electric automobile inevitably.Motor and the electric connector between the corresponding control system that is used for realizing the distribution box of electric automobile is exactly of numerous connectors on the electric automobile; Because big (rated operational current can reach 300A for less and current delivery power between motor and the control system in the space of the distribution box of electric automobile; Therefore also want to satisfy high power transmission when proof voltage 2500V), requiring this electric connector should satisfy the requirement of small size.And present electric connector mostly can't satisfy above-mentioned requirements; Trace it to its cause, present electric connector mostly comprises metal shell and be assemblied in the contact in the metal shell through insulator, and said insulator to be jump ring through correspondence fixedly be assemblied in the metal shell; In order to satisfy the requirement of high power transmission; Creepage distance between contact and the metal shell and electric clearance all have specific requirement, and this just needs to increase the axial dimension of insulator, and in order insulator to be installed in the metal shell; Then need make the tail end place of metal shell have certain installation surplus with respect to insulator; Said structure makes electric connector or overall dimension excessive, or can't satisfy power requirement, therefore can't be applied between the motor and control system of electric automobile.In addition, owing to receive the restriction in the space in the distribution box, the also extremely difficult operation of the wiring of existing electric connector, this makes wiring quality to guarantee on the one hand, has also increased staff's work difficulty on the other hand.
Summary of the invention
The purpose of the utility model is to provide a kind of single core large-current electric connector, to solve the problem that existing electric connector is not suitable for little space, large-power occasions.
In order to address the above problem; Single core large-current electric connector of the utility model adopts following technical scheme: a kind of single core large-current electric connector; Comprise housing and be assemblied in the contact in the said housing through insulator; Said insulator is provided with projection in the outer peripheral face at its tail end place, and the circumferential shell wall of housing is provided with the hole clipping corresponding with said projection, and said projection is installed by force and is located in the corresponding hole clipping.
The tail end place of said insulator is provided with outer turning edge, and the said outer front end face that turns edge cooperates with the rear end face block of said housing.
Said insulator cooperates with the housing location through the opening of being located at the positioning key on its tail end place outer peripheral face and being located at the housing tail end.
Said contact is a jack contact, and contact is through being located at dismantled and assembled being assigned on the insulator of jump ring on the insulator.
Said contact is a contact pin contacting piece, and the contact screw fit is on said insulator.
Because single core large-current electric connector of the utility model is provided with projection on its insulator; On the circumferential shell wall of its housing housing, be provided with the hole clipping corresponding with said projection, said projection is installed by force and is located in the corresponding hole clipping, therefore need not to fix insulator through parts such as jump rings again; Thereby can correspondingly shorten the axial dimension of housing; When the design electric connector, the needs that only need assurance insulation physical efficiency to satisfy the creepage distance of corresponding power get final product, and then can reduce the overall dimensions of electric connector; Make it satisfy the requirement of little space, the use of powerful occasion, solved the problem that existing electric connector is not suitable for little space, large-power occasions.
