Description

Mounting structure of rotary encoder

technical field

The utility model relates to a mounting seat structure of a rotary encoder.

Background technique

In the prior art, a gap is opened on the outer periphery of the housing of the mounting seat of the rotary encoder, the core of the rotary encoder is placed on the mounting seat, the communication cable is drawn out from the gap, and a PC plastic sheet or rubber is pasted on the gap. piece. The mounting seat of the rotary encoder has poor appearance and is easily damaged, and external contaminants easily enter the interior of the mounting seat, resulting in poor use effect of the rotary encoder.

SUMMARY OF THE INVENTION

In view of this, the purpose of the present utility model is to provide a mounting seat structure of a rotary encoder with a casing with a notch and a sealing plate connected in an arc, which is beautiful and has a long service life.

In order to achieve the above purpose, the present invention adopts such a rotary encoder mounting base structure, which includes a casing with a gap, and an inner core of the rotary encoder arranged in the casing. The mounting seat structure also includes a sealing plate for covering the gap and connecting with the casing in a circular arc, and the cable is formed by the through hole on the sealing plate or the sealing plate and the gap being closed. through the round hole. Compared with the prior art, the beneficial technical effect created by the present invention is that: through the arrangement of the above structure, the sealing plate is ingeniously connected to the casing at the notch, and the old way of pasting PC plastic sheets or rubber sheets is no longer used, and the appearance is improved. Beautiful and stable structure, the weak adhesive layer will not be damaged due to the pulling of the cable or other external forces, and the service life is long.

In particular, two sides of the sealing plate are provided with wings, the casing is provided with vertical half grooves on both sides adjacent to the notch, and the wings and the half grooves are matched and connected. The outer periphery of the casing is formed, the inner core is provided with a circuit board matching the inner section of the casing, and the wing plate is pressed to the half groove by the periphery of the circuit board. The wing plate is crimped to the half-groove through the periphery of the circuit board, no other locking device is required, the number of components is small, and the joint degree is high.

In particular, an arc-shaped edge is formed at the bottom of the notch, an arc-shaped notch is formed at the lower end of the sealing plate, and the arc-shaped notch is connected with the arc-shaped edge to form the circular hole. The communication cable is drawn out from the circular hole formed by connecting the arc-shaped notch and the arc-shaped edge.

In particular, the bottom of the notch forms an arc-shaped edge, the lower end of the sealing plate forms an arc-shaped end that fits with the arc-shaped edge, the sealing plate is provided with a through hole, and the through hole Concentric with said arcuate end. Through the arrangement of the above structure, the communication cable is led out from the via hole on the arc-shaped end. As long as the gap on the casing is larger than the outer diameter of the cable by a certain margin, the communication cable with different outer diameter can be selected according to different situations. Wire, great flexibility in production.

Description of drawings

Fig. 1 is the schematic diagram of the mounting seat structure of the rotary encoder in the first embodiment of the present invention;

FIG. 2 is a schematic diagram of the structure of the mounting seat of the rotary encoder in the second embodiment of the present invention.

In the figure: 1. Sealing plate; 11. Arc-shaped notch; 12. Wing plate; 2. Shell; 21. Arc-shaped edge; 31. Via hole; 32. Arc-shaped end.

Detailed ways

As shown in Figures 1-2, a mounting seat structure of a rotary encoder includes a housing 2 with a gap, and an inner core of the rotary encoder disposed in the housing 2. The mounting seat structure of the rotary encoder further includes The sealing plate 1 is used to cover the gap and is connected with the casing 2 in a circular arc, and the cable passes through the through hole 31 on the sealing plate or the circular hole formed by closing the sealing plate 1 and the gap.

The two sides of the sealing plate 1 are provided with wings 12, the casing 2 is provided with vertical half grooves on both sides adjacent to the gap, the wings 12 and the half grooves are matched and connected to form the outer circumference of the casing, The circuit board with matching inner section of the shell 2 presses the wing plate 12 to the half groove by the periphery of the circuit board.

An arc-shaped edge 21 is formed at the bottom of the notch, an arc-shaped notch 11 is formed at the lower end of the sealing plate 1 , and the arc-shaped notch 11 is connected with the arc-shaped edge 21 to form a circular hole.

In the second embodiment, the difference from the first embodiment is that the lower end of the sealing plate 1 is formed with an arc-shaped end portion 32 that fits with the arc-shaped edge 21 , and a through hole 31 is formed on the sealing plate, and the through hole 31 and the arc-shaped end portion 32 are concentric. set up.
