Technical Field

The utility model relates to the technical field of automobile parts, in particular to an automobile wire harness junction box.

Background

A relay is provided in an automobile to control various electrical components, and thus the relay is very important. Since the environment on an automobile, for example, on the chassis of the automobile, is relatively severe, the damage rate and the failure rate of the relay are relatively high, which requires good performance of the wire harness junction box. The heat dissipation in the junction box is poor, the condition of explosion can appear, and the life-span of very influence relay.

SUMMERY OF THE UTILITY MODEL

The utility model mainly aims to provide an automobile wire harness junction box, wherein the X-shaped reinforcing ribs are arranged on the inner side of a lower cover, so that the integral strength of the junction box is enhanced, and a gap is arranged between a relay seat and the lower cover to enhance air flow, so that the heat of a junction box body can be better radiated; through setting up V type heat insulating board, both fixed the position between relay seat and the lower cover, better separate relay seat and lower cover again, better increase radiating effect.

In order to solve the above technical problem, the present invention discloses an automotive wire harness junction box, comprising: an upper cover; a junction box body connected to the upper cover; the lower cover is connected to the bottom of the junction box body; the nano composite ceramic layer is coated on the inner side of the lower cover; the X-shaped reinforcing ribs are arranged in the lower cover and protrude inwards at the periphery; v-shaped heat insulation plates clamped at four corners in the lower cover; a relay seat clamped in the V-shaped heat insulation plate.

According to an embodiment of the present invention, the upper cover and the junction box body are connected by a snap.

According to an embodiment of the present invention, the lower cover and the terminal box body are connected by a snap.

According to an embodiment of the present invention, the bottom of the lower cover is provided with a wire connection port.

According to an embodiment of the present invention, the included angle of the V-shaped heat insulation plate is 90 °.

Compared with the prior art, the application can obtain the following technical effects:

1) the X-shaped reinforcing ribs are arranged on the inner side of the lower cover, so that the overall strength of the junction box is enhanced, and the gap is formed between the relay seat and the lower cover to enhance air flow, so that the junction box body can be better radiated; through setting up V type heat insulating board, both fixed the position between relay seat and the lower cover, better separate relay seat and lower cover again, better increase radiating effect.

Of course, it is not necessary for any one product to achieve all of the above technical results simultaneously in the practice of the present invention.

Reference numerals

The structure comprises an upper cover 10, a junction box body 20, a lower cover 30, a nano composite ceramic layer 40, X-shaped reinforcing ribs 50, a V-shaped heat insulation plate 60 and a relay seat 70.

Detailed Description

Embodiments of the present application will be described in detail with reference to the drawings and examples, so that how to implement technical means to solve technical problems and achieve technical effects of the present application can be fully understood and implemented.

Referring to fig. 1 and 2, fig. 1 is a perspective view of an automotive wire harness junction box according to an embodiment of the present application. Fig. 2 is a top view of the lower cap 30 of fig. 1 according to an embodiment of the present application. As shown, an automotive wire harness junction box includes: an upper cover 10; a junction box body 20 connected to the upper cover 10; the lower cover 30 is connected to the bottom of the junction box body 20, and a wiring port is formed in the bottom of the lower cover 30; a nano composite ceramic layer 40 coated on the inner side of the lower cover 30; an X-shaped reinforcing rib 50 which is arranged in the lower cover 30 and protrudes inwards at the periphery; v-shaped heat insulation plates 60 clamped at four corners in the lower cover 30; a relay seat 70 clamped in the V-shaped heat insulation board 60.

In the embodiment of the utility model, the junction box body 20 is connected to the bottom of the upper cover 10, the lower cover 30 is connected to the bottom of the stringed song body, and the nano-composite ceramic layer 40 is coated on the inner surface of the lower cover 30, so that the heat dissipation effect is enhanced. The X-shaped reinforcing ribs 50 protruding inwards are arranged on the periphery in the lower cover 30, so that the overall strength of the junction box is enhanced, and the gap is arranged between the relay seat 70 and the lower cover 30 to enhance air flow, so that the junction box body 20 can be better radiated. The V-shaped heat insulation plates 60 are clamped at four corners in the lower cover 30, and the relay seat 70 is clamped and connected in the V-shaped heat insulation plates 60, so that the position between the relay seat 70 and the lower cover 30 is fixed, the relay seat 70 is better separated from the lower cover 30, and the heat dissipation effect is better increased.

Preferably, the upper cover 10 and the junction box body 20 are snap-coupled, and the lower cover 30 and the junction box body 20 are snap-coupled. The whole connection of the junction box is very stable.

It is worth mentioning that the angle of the V-shaped heat insulating plate 60 is 90 °. The angle set in this way is better matched with the lower cover 30, and is very convenient.
