Description
Technical field
The present invention relates to a kind of replaceable contact pin components of direct-current charging interface.
Background technology
By the DC charging rifle that GB/T11918-2015 makes, only a kind of charge mode, i.e., mounted in fixed charging pile
On.The quantity of charging pile is far below the sales volume of new-energy automobile at present, and what is thus caused electrically-charging equipment supply falls short of demand shows
As but also DC charging rifle is stored in overload, high intensity use state for a long time, it is easy to inside contact pin be caused to wear.Tradition
If DC charging rifle contact pin occur wearing; bending is needed to replace entire charging gun harness, it is cumbersome.And waste of resource.
Invention content
The object of the present invention is to provide a kind of replaceable contact pin component of direct-current charging interface, to solve existing DC charging rifle
Entire DC charging rifle harness is needed to change after abrasion, replaces trouble, and the problem of waste of resource.
In order to solve the above technical problems, 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, elastic connecting
Contact element is set between head and the sleeve of contact pin matrix, and sleeve and contact pin base elastomer is made to contact conduction；Insulator cap passes through lock
Tight part is fixed on the head of contact pin matrix.
Further, the inside of sleeve is equipped with is arranged on card slot with the matched card slot of resilient contact, resilient contact
It is interior.
Further, a step and location hole are equipped in insulator cap.
Further, insulator cap is fixed on the head of sleeve by locking member.
Further, locking member is threadedly coupled with contact pin matrix.
Further, locking member is screw or pin.
Beneficial effects of the present invention are：In actual use, the tail portion of contact pin matrix can crimp cable and be fixed on
In DC charging rifle, sleeve and the corresponding jack contact in DC charging socket are conductive.Sleeve in the application is replaceable, is grinding
It can individually be aligned and be replaced after damage, not needed to entire DC charging rifle harness.Also, it can pass through after sleeve is worn
Removing and locking the replacement to realize sleeve again for locking member is easy to operate, quick.Also, the power of the locking of resilient contact
Not only it ensure that structural strength but also can have been contacted for the end face of contact pin matrix and sleeve and lasting normal pressure is provided, and ensured contact pin component
Overcurrent capability.

Specific embodiment
The specific embodiment of the present invention is described below, in order to facilitate understanding by those skilled in the art this hair
It is bright, it should be apparent that the present invention is not limited to the range of specific embodiment, for those skilled in the art,
As long as various change in the spirit and scope of the present invention that appended claim limits and determines, these variations are aobvious and easy
See, all are using the innovation and creation of present inventive concept in the row of protection.
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 are set in the head of contact pin matrix 1 and pass through locking member 5 and lock, and resilient contact 4 is set in
Between the head of contact pin matrix 1 and sleeve 2, make sleeve 2 and 1 Elastic Contact of contact pin matrix conductive；Insulator cap 3 passes through locking member 5
On the head of contact pin matrix 1.
According to one embodiment of the application, the inside of sleeve 2 is equipped with and 4 matched card slot 21 of resilient contact, bullet
Property contact 4 is arranged in card slot 21.
According to one embodiment of the application, as shown in figure 4, be equipped in insulator cap 3 step 31 matched with nut and
Location hole 32 matched with fastener.
According to one embodiment of the application, insulator cap 3 is fixed on sleeve 2 by the locking member 5 extended into insulator cap 3
Head.
According to one embodiment of the application, locking member 5 is threadedly coupled with contact pin matrix 1.
According to one embodiment of the application, locking member 5 is screw or pin.
The assembling flow path of this contact pin is：Resilient contact 4 is encased in sleeve 2 first, then is inserted into contact pin base together
On body 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 replacement flow of this contact pin is：Screw assembly is screwed off from contact pin matrix 1 with specific purpose tool, by 3 He of insulator cap
2 priority of sleeve there are abrasion is removed from contact pin matrix 1.The new casing equipped with resilient contact 4 is inserted into contact pin matrix
1, then lock all parts by assembling flow path.
To sum up, after the sleeve 2 in the application is worn, can set be realized with locking again by removing for locking member 5
The replacement of cylinder 2 is easy to operate, quick.Also, insulator cap 3 is equipped on the head of sleeve 2, can prevent operating personnel's hand from getting an electric shock.This
Outside, resilient contact 4 is equipped between contact pin matrix 1 and sleeve 2, the power of the locking of resilient contact 4 both ensure that structural strength
It can be contacted again for the end face of contact pin matrix 1 and sleeve 2 and lasting normal pressure is provided, ensure the overcurrent capability of contact pin component.
