Description

Terminal box fixing plate boss chamfer guide structure

technical field

The utility model relates to a chamfering guide structure of a boss of a fixing plate, in particular to a chamfering guide structure of a boss of a fixing plate used for fixing a terminal box.

Background technique

The fixing plate is an object used for fixing the terminal box of the motor with a terminal box structure. In order to meet the customer’s lateral impact test on the terminal box, the fixing plate is equipped with boss structures on both sides. The increase of the boss structure meets the requirements to a certain extent. The lateral impact resistance of the terminal box is improved, but at the same time it increases the difficulty of installing the terminal box to the fixed plate.

To solve the problem of installing the terminal box to the fixing plate, the usual method is to rely on the wear of the cutting edge of the mold during use. After the cutting edge is worn, the rounded corners will be naturally formed on the boss of the fixing plate. This method has a long cycle, and the second is The difficulty of installation is not greatly reduced.

Utility model content

The purpose of the utility model is to provide a terminal box fixing plate boss chamfering guiding structure. The utility model can not only reduce the difficulty of buckling the terminal box into the fixing plate, but also reduce the processing cycle and make the service life of the processing equipment unaffected.

The technical scheme of the utility model: terminal box fixing plate boss chamfering guide structure, characterized in that: it includes a fixing plate body, and the fixing plate body is provided with a convex through hole for fixing the terminal box, two convex through holes The inner angle is the missing corner of the hypotenuse of 135°. There are punching bosses on both sides of the rectangular through hole of the convex through hole. The punching bosses are arranged perpendicular to the fixed plate body. The chamfer of the hypotenuse.

In the aforementioned chamfering guide structure of the boss of the terminal box fixing plate, the length of the hypotenuse of the missing corner is the same as that of the chamfer.

In the aforementioned chamfering guide structure of the boss of the terminal box fixing plate, there are two convex through holes arranged symmetrically.

In the aforementioned terminal box fixing plate boss chamfering guide structure, the punched bosses on both sides of the rectangular hole of the convex through hole are arranged symmetrically.

Compared with the prior art, the utility model can obtain the chamfered boss by punching. The utility model can not only reduce the difficulty of snapping the terminal box into the fixing plate, but also reduce the processing cycle and make the processing equipment more efficient. Lifespan is not affected. The utility model can not only ensure the lateral strength after installation, but also realize the purpose of reducing the difficulty of buckling the terminal box into the fixing plate without changing the size of the terminal box installation fixing plate. The utility model has the advantages of convenient processing, short processing time and high processing efficiency.

Description of drawings

Fig. 1 is a structural representation of the utility model;

Fig. 2 is the assembly schematic diagram of the present utility model;

Fig. 3 is a structural schematic diagram of the cutting process of the fixed plate of the present invention.

The marks in the accompanying drawings are: 1-fixed plate body, 2-convex through hole, 3-punched boss, 4-cut corner, 5-chamfer, 6-terminal box, 7-square hole with right angle notch.

Detailed ways

The utility model will be further described below in conjunction with the accompanying drawings and embodiments, but it is not used as a basis for limiting the utility model.

Example. The chamfering guide structure of the terminal box fixing plate boss is shown in Figures 1 and 2, including the fixing plate body 1, and the fixing plate body 1 is provided with a convex through hole 2 for fixing the terminal box 6, and a convex through hole 2 The two internal angles are the notch 4 of the hypotenuse of 135 °, and the two sides of the rectangular through hole of the convex through hole 2 are provided with punching bosses 3, and the punching bosses 3 are vertically arranged with the fixed plate body 1. The boss 3 is provided with a chamfer 5 of 135° of hypotenuse.

The length of the hypotenuse of the notch 4 is the same as that of the chamfer 5 .

There are two convex through holes 2 arranged symmetrically.

The punched bosses 3 on both sides of the rectangular hole of the convex through hole 2 are arranged symmetrically.

The utility model is processed as follows, as shown in Figure 3, the square hole 7 with a right-angle notch punched out during the cutting is made of a 6.2mm*4.4mm rectangular hole corresponding to the installation angle size of the terminal box and a side length of 0.85mm. mm right-angle notch constitutes, one side of punching boss 3 is along the vertex of the right-angle notch, and the other side is along the rectangular hole limit, and the bending height is 3.9mm. The punching boss 3 folded at 90° is made up of a 3.9mm boss and a chamfer 5 .

The chamfer 5 of the punched boss 3 of the fixing plate acts as a snap-in guide when the terminal box is installed on the fixing plate. After the punching boss 3 is folded up, a gap of 135° is naturally left on the oblong hole.

The utility model can obtain the chamfered boss by punching. The utility model can not only reduce the difficulty of snapping the terminal box into the fixing plate, but also reduce the processing cycle and keep the service life of the processing equipment unaffected. The utility model can not only ensure the transverse strength after installation, but also realize the purpose of reducing the difficulty of buckling the terminal box into the fixing plate without changing the size of the terminal box installation fixing plate. The utility model has the advantages of convenient processing, short processing time and high processing efficiency.
