DETAILED DESCRIPTION

[0030] To make the purpose, technical scheme and advantages of the utility model clearer and more apparent, the following will combine the drawings to make a detailed description of the embodiments of the utility model. It should be noted that the following described embodiments and features in the embodiments can be combined with each other in the case of no conflict.

[0031] Many different embodiments or examples are provided below to realize the structure of the utility model.

[0032] Referring to Figures 4-12 , the utility model provides a kind of encoder, including shell 1 and base 2, shell 1 is generally made of metal material, base 2 is generally made of plastic piece, the shell 1 is connected and fixed with base 2, specific connection mode is the technology known in the art, not expand here, the base 2 is provided with rotating wheel 3, the rotating wheel 3 is provided with switching piece 4, the switching piece 4 can be rotated with rotating wheel 3, the base 2 is also provided with conductive terminal 5, and conductive terminal 5 can be combined with base 2 by injection molding, the switching piece 4 can be contacted with conductive terminal 5, so, when switching piece 4 rotates with rotating wheel 3, the abutting portion on switching piece 4 rotates on conductive terminal 5 and has different positions, so that electrical signal can be formed to realize the control of mouse roller to computer, in the front-back direction of encoder, the shell 1 and base 2 have first combination area C, the first combination area C can be the gap A shown in Figure 1 ; also as shown in Figure 7 or Figure 11 , in first combination area C, the base 2 and shell 1 abut, and the first combination area C is the abutting position of base 2 and shell 1. The top of the shell 1 or base 2 is provided with shielding part 6, and the shielding part 6 can be integrally formed with the shell 1 or base 2;The shielding part 6 extends along the front-back direction, and the shielding part 6 partially or entirely covers the first combination area C, referring to Figure 4 Figure 7 or Figures 9-11As shown, the shielding part 6 shields the entire first combination area C to form a better dust and water blocking effect. The design of the shielding part 6 is such that liquid contaminants such as beverages, water, oil stains and dust impurities falling on the encoder will be shielded by the shielding part 6, and the penetration of the liquid contaminants from the first combination area C into the product inner cavity is reduced or eliminated, thereby preventing or reducing damage to the product, ensuring the normal or smooth operation of the encoder, and the structure is simple and compact and easy to implement.

[0033] As shown in the drawings, Figures 4-6 or Figures 9-10 As shown, in some embodiments of the utility model, in the left-right direction of the encoder, the shielding part 6 is arched with the middle higher and the two sides lower, and the arched shielding part 6 is similar to a roof. When the dust or liquid falls on the shielding part 6 from top to bottom, it will slide down along the left and right sides of the shielding part 6 under the action of gravity and be discharged, avoiding accumulation on the encoder, which is conducive to preventing or reducing the entry of dust or liquid from the first combination area C into the encoder.

[0034] As shown in the drawings, Figures 4-5 or Figure 9 、 Figure 10 As shown, in some embodiments of the utility model, between the shell 1 and the base 2 in the left-right direction of the encoder, there is also a second combination area D, as shown in Figures 4-5 When the shell 1 is made of metal, the shielding part 6 is formed by bending the top of the shell 1. At this time, the shielding part 6 has not covered the second combination area D. After the liquid or dust enters from the second combination area D, it is located in the left and right side wall areas of the base 2, and it is not easy for the liquid or dust to enter the encoder from the front. It can be understood that when the encoder is used for a long time or the liquid flow is large, it is not excluded that the liquid or dust will enter the encoder from the front after passing through the second combination area D. Therefore, as shown in Figure 9 and Figure 10 The shielding part 6 and the base 2 are integrally formed as plastic parts, and the shielding part 6 can be designed to be wider in the left and right directions, so that the shielding part 6 covers part or all of the second combination area D, thereby better preventing the entry of liquid or dust into the encoder.

[0035] As shown in the drawings, Figure 7 In some embodiments of the utility model, the shielding part 6 is arranged on the shell 1, and the shielding part 6 abuts against the top surface of the base 2. In other embodiments, as shown in Figure 11 The shielding part 6 is arranged on the base 2, and the shielding part 6 abuts against the top surface of the shell 1. This structure makes it difficult for dust or liquid to enter the encoder from below the shielding part 6, further improving the waterproof and dustproof effect.

When the encoder is used, the rotating shaft is inserted into the first jack 34 and the second jack 36, the structure in the embodiment makes the rotating shaft easy to be inserted into the second jack 36 (the second jack 36 does not have to be interference fitted with the rotating shaft to realize sound insulation), and after being inserted into the first jack 34, the hole wall of the first jack 34 is covered on the rotating shaft due to the elasticity (the first jack 34 is designed to be interference fitted with the rotating shaft), so that after the wheel body 3 is assembled with the rotating shaft, there is no gap between the wheel body 3 and the rotating shaft at the sound attenuation piece 33, and referring to Figure 8 When the encoder rotates, the click sound between the positioning elastic sheet 7 and the positioning tooth 35 on the rotating wheel 3 is blocked by the sound attenuation piece 3, so that the click sound is prevented from being transmitted from the gap between the rotating wheel 3 and the rotating shaft, which is beneficial to reduce the noise of the encoder during use (such as when the mouse roller rolls).
