Technical Field

The utility model relates to a sub-plug technical field specifically belongs to a public plug is used in battery load test.

Background

When carrying out load test to the battery, connect the public affairs that the group battery corresponds on the load machine, then all connect public affairs to insert each group battery according to the technological requirement, carry out heavy current test and examine entirely, the shortcoming is because be heavy current discharge, public affairs insert and connecting wire just generate heat seriously in very short time, lead to can not quick lasting test, must wait to cool off the back and can test again, seriously influence efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a public plug is used in battery load test has overcome the not enough of prior art.

In order to solve the above problems, the utility model adopts the following technical proposal:

the utility model provides a public plug is used in battery load test, includes connecting plate and sub-plug, the connecting plate include two square shells, the bottom of square shell be equipped with the heat transfer frame, the heat transfer frame on install heat conduction metal sheet, square shell in install each other contactless positive plate and negative plate, the rear portion of negative plate be connected with the negative pole bus, the rear portion of positive plate be connected with positive bus, negative plate and positive plate on be connected with a plurality of sub-plug, the sub-plug be located the outside of connecting plate, the square shell intussuseption of connecting plate be filled with insulating heat conduction silica gel.

Furthermore, the cathode bus and the anode bus are silica gel cables.

Further, still install metal heat dissipation frame on the protective housing of sub-plug, heat dissipation frame and the protective housing of sub-plug between fill and have heat conduction silicone grease.

Furthermore, a plurality of radiating fin plates are arranged on the surfaces of the left side and the right side of the radiating frame.

Compared with the prior art, the utility model discloses an implement the effect as follows: the heat conducting silica gel is filled in the connecting plate of the male plug, the positive plate and the negative plate are separated by the heat conducting silica gel, and the heat conducting metal plate is arranged at the bottom of the shell of the connecting plate, so that heat generated in the connecting plate when the male plug is used can be transferred to the heat conducting metal plate through the insulating heat conducting silica gel, and the heat generated in the connecting plate can be dissipated in time; in addition, be equipped with metal heat dissipation frame on sub-plug's the protective housing, still be equipped with a plurality of heat dissipation fin on the surface on heat dissipation frame's the left side and the right side, can make the heat that sub-plug department produced by in the conduction air relatively fast, in addition, set up a plurality of sub-plugs on the connecting plate and can once carry out the load test of a plurality of batteries, and it is great to generate heat when one of them sub-plug, and when the heat was not in time scattered, can change and test on another sub-plug, this public plug convenient to use, the radiating effect is good.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation to be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

In the description of the present invention, it is to be noted that, unless otherwise explicitly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; may be directly connected or indirectly connected through an intermediate. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

As shown in fig. 1-4, a public plug is used in battery load test, including connecting plate and sub-plug 6, the connecting plate includes two square outer shells 1, two square outer shells 1 symmetry are installed together, the bottom of square outer shell 1 is equipped with heat transfer frame 11, install heat conduction metal sheet 10 on the heat transfer frame 11, install each other contactless positive plate 3 and negative plate 5 in the square outer shell 1, the intussuseption of square outer shell 1 of connecting plate is filled with insulating heat conduction silica gel 7, heat conduction silica gel 7 separates positive plate 3 and negative plate 5, and absorb and conduct the heat of positive plate 3 and negative plate 5, give heat conduction metal sheet 10 with the heat conduction, the heat that makes the interior production of connecting plate can in time be dispelled.

The rear portion of negative plate 5 is connected with negative bus 4, and the rear portion of positive plate 3 is connected with anodal bus 2, and negative bus 4 and anodal bus 2 are the silica gel cable, are convenient for the heat loss that negative bus 4 and anodal bus 2 produced.
