Abstract

The invention discloses an encoder base and an encoder using the same. The encoder base comprises a plurality of groups of terminal hardware sheets and a plastic body wrapped outside the terminal hardware sheets in modeling mode, wherein each terminal hardware sheet comprises a terminal and an electric brush part, electric brushes of the electric brush part are formed in stamping forming mode and higher than the plane of the electric brush part, an avoidance position is arranged under the electric brushes, an extending part is arranged on the lateral surface of the electric brush part and adhered onto the bottom surface of the electric brush part after being bent so as to cover the avoidance position, and a plastic body is integrally wrapped and modeled with the extending part. The extending part is adhered onto the bottom surface of the electric brush part after being bent so as to cover the avoidance position, and accordingly the electric brushes cannot be damaged due to mutually staggered distribution. When the encoder base is used on the encoder, a bottom cover for protecting the electric brushes is not needed to be additionally arranged, the integral thickness of the encoder is remarkably improved, the encoder base and the encoder are waterproof, further materials are saved, and assembling hour is reduced.

Example Embodiment

[0020] reference Figure 1 to Figure 5 As shown in the terminal hardware and encoder base structure, the encoder base 100 includes several sets of terminal hardware 110 and a plastic body 120 overmolded outside the terminal hardware 110. The terminal hardware 110 includes a terminal 111 and a brush Part 112, the brush of the brush part 112 is higher than the plane of the brush part due to the stamping and forming, and the lower part of the brush is to avoid vacancies. There is an extension 113 on the side of the brush part 112. The extension 113 is bent and attached to The bottom surface of the brush portion 112 covers the vacant space, and the plastic body 120 wraps the brush portion 112 and the extension portion 113 as a whole.
[0021] reference Image 6 The encoder shown includes a base 210, a code disc 220 in contact with the brush part in the accommodating cavity of the base 210, and a rotating shaft 230 inserted in the center hole of the code disc 220, abutting against The shrapnel 240 of the wavy teeth of the code disc 220, the sleeve 250 sleeved on the rotating shaft 230 and covering the base 210, the waterproof ring 260 clamped between the rotating shaft 230 and the sleeve 250, and the underside of the base 210 The bracket 270 envelops the base 210 and the shaft sleeve 250, wherein the base 210 is the aforementioned encoder base.
[0022] reference Figure 7 The encoder shown includes a base 310, a code disk 340 with a central hole in contact with the brush portion in the accommodating cavity of the base 310, and an elastic piece 350 contacting the wavy teeth of the code disk 340 , The rotor 360 located in the center hole of the code disc 340, the shaft sleeve 370 covering the base 310, the shaft 380 inserted in the shaft sleeve 370 and abutting against the rotor 360, clamped between the shaft 380 and the shaft sleeve 370 The intermediate collar 390 and the bracket 300 sleeved on the rotating shaft and enveloping the shaft sleeve and the base, wherein the base 310 is the aforementioned encoder base. reference Figure 8 Of course, a switch contact 311 can also be provided in the center of the accommodating cavity of the base 310. The encoder also includes a switch contact 320 that dynamically contacts the switch contact 311 and a silicone cap 330 that presses the switch contact 320. The silicone cap 330 abuts the rotor 360, so that the encoder has a switch function.
[0023] Of course, the above embodiments are only to illustrate rather than limit the present invention. The above are only preferred embodiments of the present invention. Therefore, all equivalent changes or modifications made in accordance with the solutions described in the scope of the patent application of the present invention are all It is included in the scope of the patent application of the present invention.
