Abstract
The utility model relates to a shield cover hasp connection structure for shield cover and connector body is connected in the high electric current connector of electric automobile, the shield cover be cylindric structure, this structure sets up a plurality of plugs at the shield cover lower extreme including distributing, the connector body at the slot unanimous with being equipped with quantity on a plurality of plugs correspond the position, plug and slot pass through interference fit's mode chucking. Compared with the prior art, the utility model has the advantages of convenient to use, safe and reliable, prevent slow -witted design.
Description
Technical field
The utility model relates to automobile height current connector field, especially relates to a kind of radome locking connection structure.
Background technology
In existing New-energy electric vehicle height current connector, use the large terminal of φ 8.0mm.This product, by increasing the design of radome, ensure that effective electric property of connector female end product and male end product.High electric current is effectively transmitted, reduces current loss.Wherein how function point is fixed in the structure of Housing at radome, this concerning product functionally play a significantly greater role that (radome is when being subject to external force 100N, can also be remained unchanged shape, size will in specification), having higher requirement especially for mechanical properties.
Utility model content
The purpose of this utility model be exactly in order to overcome above-mentioned prior art exist defect and a kind of radome locking connection structure is provided.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of radome locking connection structure, for the connection of radome and connector body in electric automobile height current connector, described radome is cylinder-like structure, this structure comprises multiple plugs that distribution is arranged on radome lower end, described connector body is being provided with the consistent slot of quantity with on multiple plug correspondence position, and plug and slot are clamped by the mode of interference engagement.
Described slot is groove wide at the top and narrow at the bottom, and comprise interconnective upper slot and lower slot, the width of described upper slot is greater than lower slot.
Described plug is herringbone structure, its head is provided with the first projection, afterbody is provided with the second projection, the outer rim width of the first described projection is greater than the width of lower slot and is less than the width of slot, the outer rim width of the second described projection is greater than the width of slot, described first protruding interference with lower slot contacted, and the described second protruding interference with upper slot contacted.
Described plug is provided with 4-8, is evenly distributed on radome lower end, and is provided with fool proof point.
The second described projection is that plane contact is protruding.
Compared with prior art, the utility model has the following advantages:
One, easy to use: this radome double card point in the bottom of radome, to be directly inserted in the slot of plastic cement, and through the press-in of relevant tool.
Two, safe and reliable: the double card point design of this radome accurately can judge whether Housingslot is accurately inserted into position, if do not put in place, the stuck point of this radome cannot insert.
Three, fool-proof design: plug is originally provided with 4 or 8, plug of the present utility model adopts fool-proof design, eliminates a slot and plug corresponding with it, after radome assembly and connection device body, can ensure that plug inserts the direction of slot unanimously, outward appearance better appearance.
Four, plane contact: because the second projection is that plane contact is protruding, intervene area is large, and can arrive the advantage that confining force is large, compared with point cantact, or linear contact lay has advantage.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pre-installation.
Fig. 2 is the partial enlarged drawing in A portion in Fig. 1.
Fig. 3 is the structural representation after the utility model is installed.
Fig. 4 is the partial enlarged drawing in B portion in Fig. 3.
Wherein: 1, connector body, 11, slot, 111, upper slot, 112, lower slot, 2, HV Terminal, 3, protective cap, 4, radome, 41, plug, 411, first is protruding, and 412, second is protruding.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment:
The electric automobile height current connector that the utility model is suitable for; fix rear with HV Terminal 2 primarily of connector body 1, radome 4 and a loop is formed to the femaleconn joined; realize current delivery function, one end of HV Terminal 2 is also provided with protective cap 3.
As illustrated in fig. 1 and 2, when the most initial pre-installed position, manually or automatic equipment by the double card point of the plug 41 of radome 4 load slot 11 li, first protruding 411 does not interfere with upper slot 111, first projection 411, when wide upper slot 111, first protruding 411 does not destroy slot 11 for little stuck point.
As shown in Figures 3 and 4, when plug 41 is pressed into final position, first protruding 411 works as by interference engagement with narrower lower slot 112, the second projection 412 and wider upper slot 111 interference engagement, interfere evenly, plane contact is larger than the contribution of stuck point to confining force of point cantact.Reach pressing-in force very little, the ideal effect that confining force is very large.Confining force is very large, can meet the particular/special requirement (when being subject to external force F=100N, can also remain unchanged shape, and relevant size is in specification) of radome.For the vibration of high electric current height concerning product, structured value secure like this must be praised highly.
