Detailed Description

The technical solutions of the present invention are explained in detail below with reference to specific embodiments, and many specific details are set forth in the following description to provide a thorough understanding of the present invention. The present invention can be embodied in many other forms than those specifically described herein, and it will be apparent to those skilled in the art that similar modifications can be made without departing from the spirit and scope of the invention.

As shown in fig. 1 to 5, the utility model provides a high-pressure copper bar protector, including upper cover 1 and base 2, upper cover 1 is connected with 2 locks of base and is formed the protection passageway 3 that is used for the high-pressure copper bar to pass through.

When the high-voltage copper bar needs to stride across the sheet metal part to be connected or is too close to the sheet metal part, the high-voltage copper bar can be arranged by passing the protective device, and the high-voltage copper bar is separated from the sheet metal part to play a role in high-voltage protection. The protective device can be arranged into an I shape and has four-direction open ends to be adapted to various copper bar structures and various copper bar connection modes, and the utilization rate is extremely high.

The formation of the protection channel is specifically as follows: the upper cover 1 is provided with a first groove 11, the base 2 is provided with a second groove 21, and the first groove 11 is communicated with the second groove 21 to form a protection channel 3.

Specifically, in order to avoid the electric crosstalk between the protection device and the sheet metal part, the upper cover 1 and the base 2 in the protection device are made of plastic nylon materials. In the fixed setting of protector and sheet metal component, the fixed second buckle 23 that is provided with on the lower surface of base 2, second buckle 23 inserts fixed spacing in the through-hole that the sheet metal component was reserved, avoids rocking of protector, protection copper bar that can be better.

In order to facilitate installing the high-pressure copper bar in protector or dismantle from protector, set up upper cover 1 and base 2 and connect for the lock, specifically do: the upper cover 1 is provided with a limiting hole 12, the base 2 is provided with a first buckle 22 in an outward extending mode, and the upper cover 1 and the base 2 are connected in a buckling mode through the first buckle 22 inserted into the limiting hole 12. The limiting holes 12 correspond to the first buckles 22 one by one. The number of the limiting holes 12 and the number of the first fasteners 22 can be set according to actual needs, for example, in this embodiment, the limiting holes 12 and the first fasteners 22 have six positions, and are respectively distributed around the corresponding upper cover 1 and the corresponding base 2.

It should be noted that the shape of the limiting hole 12 and the first buckle 22 may be various, such as rectangular, triangular, circular, etc.

In this embodiment, when the positive pole and the negative pole of battery module were connected to the outer positive negative terminal of battery package box through the high-pressure copper bar, the high-pressure copper bar need protect through protector this moment to avoid the high-pressure copper bar distance of positive, negative terminal extremely near, have the defect of great short circuit risk. Set up the baffle in the protector this moment, this baffle adopts the working of plastics in order insulating, the baffle sets up along protection passageway 3, will protect passageway 3 and divide into two, the baffle is fixed in the second recess 21 of base 2, the baffle highly stretches out second recess 21 for after upper cover 1 and the 2 locks of base, the baffle just in time with 1 butt of upper cover or the less clearance setting in interval, avoid the positive terminal of high-pressure copper bar in two protection passageways and the defect of negative terminal mutual contact.

The use as a process: the upper cover 1 and the base 2 are separated, the high-voltage copper bar is distributed in the second groove 21 of the base 2, then the upper cover 1 is buckled, the limiting hole 12 is inserted through the first buckle 22 to realize that the upper cover 1 and the base 2 are buckled and fixed, then the second buckle 23 is inserted into a through hole reserved for the sheet metal part, and the base 2 and the sheet metal part are fixedly connected.

It should be noted that a plurality of tie holes are formed in the bottom of the second groove 21 of the base 2, and the tie carries out limiting and fixing on the high-voltage copper bar through the tie holes, so that the high-voltage copper bar is stably fixed in the protective channel 3.

The above, only be the embodiment of the preferred of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is in the technical scope of the present invention, according to the technical solution of the present invention and the utility model, which are designed to be replaced or changed equally, all should be covered within the protection scope of the present invention.
