Abstract
The invention discloses a contact pin assembly capable of achieving direct-current charging interface replacement. The contact pin assembly comprises a contact pin matrix, an elastic contact part, an insulation cap and a sleeve; the sleeve is arranged at the head of the contact pin matrix in a sleeving mode and locked through a locking part, and the elastic contact part is arranged between the head of the contact pin matrix and the sleeve in a sleeving mode, so that the sleeve and the contact pin matrix are in elastic contact for conduction. The insulation cap is fixed to the head of the contact pin matrix through a locking part. The sleeve in the contact pin assembly can be replaced and can be independently replaced after being abraded, and a whole direct-current charging gun wiring harness does not need to be replaced. Besides, when the sleeve is abraded, the sleeve can be replaced by taking down and re-locking the locking part, and operation is convenient and fast. Besides, the locking force of the elastic contact part guarantees the structural strength and can provide continuous positive pressure for end face contact of the contact pin matrix and the sleeve, and the overcurrent capacity of the contact pin assembly is guaranteed.
Description
Technical field
The present invention relates to a kind of replaceable contact pin component of direct-current charging interface.
Background technology
The DC charging rifle made by GB/T11918-2015, only has a kind of charge mode, is i.e. contained on fixing charging pile.The quantity of charging pile is far below the sales volume of new-energy automobile at present, thus causes the electrically-charging equipment phenomenon that supply falls short of demand, also makes DC charging rifle be stored in overload, high intensity use state for a long time, it is easy to cause inside contact pin to wear and tear.If traditional DC charging rifle contact pin occurs that abrasion then needs bending to change whole charging gun wire harness, cumbersome.And waste resource.
Summary of the invention
It is an object of the invention to provide a kind of replaceable contact pin component of direct-current charging interface, to need to change whole DC charging rifle wire harness after solving the abrasion of existing DC charging rifle, it changes trouble, and the problem of waste resource.
For solving above-mentioned technical problem, the present invention provides a kind of replaceable contact pin component of direct-current charging interface, including contact pin matrix, resilient contact, insulator cap and sleeve；Sleeve is set in the head of contact pin matrix and is locked by locking member, and resilient contact is set between head and the sleeve of contact pin matrix, makes sleeve contact conduction with contact pin base elastomer；Insulator cap is fixed on the head of contact pin matrix by locking member.
Further, the inner side of sleeve is provided with the draw-in groove matched with resilient contact, and resilient contact is arranged in draw-in groove.
Further, a step and hole, location it are provided with in insulator cap.
Further, insulator cap is fixed on the head of sleeve by locking member.
Further, locking member is threadeded with contact pin matrix.
Further, locking member is screw or pin.
The invention have the benefit that in actual use, the afterbody of contact pin matrix can crimp cable and be fixed in DC charging rifle, and sleeve jack contact corresponding with in DC charging socket conducts electricity.Sleeve in the application is replaceable, and can individually align upon wear is replaced, it is not necessary to by whole DC charging rifle wire harness.Further, after there is abrasion in sleeve can by locking member taking off and locking realizes the replacing of sleeve again, easy to operate, quick.Further, the power of the locking of resilient contact not only ensure that structural strength but also can provide lasting normal pressure for the end contact of contact pin matrix and sleeve, it is ensured that the overcurrent capability of contact pin component.

Detailed description of the invention
Below the detailed description of the invention of the present invention is described; so that those skilled in the art understand the present invention; it is to be understood that; the invention is not restricted to the scope of detailed description of the invention; from the point of view of those skilled in the art; as long as various changes limit and in the spirit and scope of the present invention that determine, these changes are apparent from, and all utilize the innovation and creation of present inventive concept all at the row of protection in appended claim.
The replaceable contact pin component of direct-current charging interface as shown in Figure 1 to Figure 3, including contact pin matrix 1, resilient contact 4, insulator cap 3 and sleeve 2, sleeve 2 is set in the head of contact pin matrix 1 and is locked by locking member 5, resilient contact 4 is set between the head of contact pin matrix 1 and sleeve 2, makes sleeve 2 and contact pin matrix 1 Elastic Contact conduction；Insulator cap 3 passes through the locking member 5 head at contact pin matrix 1.
An embodiment according to the application, the inner side of sleeve 2 is provided with the draw-in groove 21 matched with resilient contact 4, and resilient contact 4 is arranged in draw-in groove 21.
An embodiment according to the application, as shown in Figure 4, is provided with the step 31 matched with nut and the hole, location 32 matched with securing member in insulator cap 3.
An embodiment according to the application, insulator cap 3 is fixed on the head of sleeve 2 by extending into the locking member 5 in insulator cap 3.
An embodiment according to the application, locking member 5 is threadeded with contact pin matrix 1.
An embodiment according to the application, locking member 5 is screw or pin.
The assembling flow path of this contact pin is: be first encased in sleeve 2 by resilient contact 4, then is inserted into together on contact pin matrix 1, insulator cap 3 is placed to the head of sleeve 2, then contact pin matrix 1, sleeve 2 and insulator cap 3 is locked with screw assembly.
The replacing flow process of this contact pin is: screwed off from contact pin matrix 1 by screw assembly with specific purpose tool, is successively taken off from contact pin matrix 1 by the sleeve 2 of insulator cap 3 and existence abrasion.The new sleeve pipe equipped with resilient contact 4 is inserted contact pin matrix 1, then by assembling flow path, all parts is locked.
To sum up, after there is abrasion in the sleeve 2 in the application, can by locking member 5 taking off and locking realizes the replacing of sleeve 2 again, easy to operate, quick.Further, the head at sleeve 2 is provided with insulator cap 3, can prevent operator's hands from getting an electric shock.Additionally, be provided with resilient contact 4 between contact pin matrix 1 and sleeve 2, the power of the locking of resilient contact 4 not only ensure that structural strength but also can provide lasting normal pressure for the end contact of contact pin matrix 1 and sleeve 2, it is ensured that the overcurrent capability of contact pin component.
