Description

Technical Field

[0001] This utility model belongs to the field of electronic encoder technology, and specifically relates to an encoder. Background Technology

[0002] An encoder is a device that encodes and converts signals or data into a signal format that can be used for communication, transmission, and storage. Electronic encoders are setting tools for electrical fire monitoring detectors. Through an electronic encoder, one can read and write the detector's address code and the alarm value of the detector's residual current. Electronic encoders are operated via a keyboard, inputting decimal numbers, making them simple and easy to learn. They can be used to read and write the detector's address and sensitivity, as well as the address and operating mode of module-type products; and they can also be used to browse equipment batch numbers.

[0003] In existing technologies, the encoder and the contact plate are usually connected by a connecting cable. The contact plate is used to detect and measure information such as the position, speed and direction of rotation or linear motion. The operator needs to hold the contact plate while holding the encoder. The position of the contact plate cannot be adjusted by directly adjusting the position of the encoder. Utility Model Content

[0004] In view of the problems raised in the background art, the purpose of this utility model is to provide an encoder to solve the problems raised in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An encoder includes a front cover and a bottom cover that are interlocked. The front cover has a button frame at its lower part and a screen frame at its upper part. A button located below the button frame of the front cover, a transparent screen frame located below the screen frame of the front cover, a motherboard, and a battery are sequentially assembled and connected between the front cover and the bottom cover. The upper part of the bottom cover has two sets of contact structures that are connected to the motherboard for signal transmission. Each contact structure includes a contact with an arc-shaped groove. Conductive silicone particles are sleeved on the two ends of the contact. An insert nut is fixedly connected to the bottom cover. A screw connected to the insert nut is slidably connected in the arc-shaped groove of the contact.

[0007] Further, the bottom cover has an arc-shaped relief groove for conductive silicone particles, and a positioning block for positioning the screw is fixedly connected to the outside of the insert nut on the bottom cover.

[0008] Further, the bottom cover has an accessory compartment located at the bottom of the battery. The accessory compartment has a sliding cover for the accessory compartment on the outside of the bottom cover. The bottom cover has a positioning groove, and the sliding cover is fixedly connected to a protrusion that matches the positioning groove. When the sliding cover is slid down, the protrusion separates from the positioning groove.

[0009] Furthermore, the upper part of the motherboard is provided with a telephone jack socket for connecting a telephone plug cable.

[0010] Furthermore, the motherboard has two through holes at its upper part, and these through holes are connected to screws.

[0011] Furthermore, the motherboard has an indicator light at its lower part, and the cover has an indicator light recess at the position corresponding to the indicator light.

[0012] Furthermore, the motherboard has a circular hole, and a cylinder is fixedly connected to the back of the button at the corresponding position of the circular hole.

[0013] Further specifying, the bottom cover is provided with an arc-shaped ear-shaped loop hole for threading a rope, and an arc-shaped oblique rib is provided inside the loop hole of the bottom cover.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] This utility model is equipped with an accessory compartment, which can carry conductive silicone particles and encoder at the same time. When the conductive silicone particles on the contact are lost or worn, spare silicone particles can be taken out from the accessory compartment for timely replacement, without the need for a separate box to hold the conductive silicone particles.

[0016] In this invention, the screw can slide within the arc-shaped groove of the contact piece. Thus, when the screw is loosened, the contact piece can slide, allowing it to rotate at different angles, thereby testing the test points in different zones.

[0017] This invention uses screws to fix the contact piece to the insert nut. In addition to fixing, the screws also conduct electricity. The contact tip of the contact piece is covered with conductive silicone particles. In addition to conducting electricity, the conductive silicone particles also serve as a soft connection with silicone buffer between the contact tip and the device under test. The motherboard achieves conductive connection with the silicone particles and the device under test through the insert nut. Attached Figure Description

[0031] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0032] like Figure 1-6 As shown, an encoder includes a front cover 1 and a bottom cover 2 that are interlocked. The lower part of the front cover 1 is provided with a button frame, and the upper part is provided with a screen frame. A button 31 located on the lower side of the button frame of the front cover 1, a transparent screen frame 32 located on the lower side of the screen frame of the front cover 1, a main board 4, and a battery 5 are sequentially assembled and connected between the front cover 1 and the bottom cover 2. The upper part of the bottom cover 2 is provided with two sets of contact structure 6 that are connected to the main board 4 for signal transmission. The contact structure 6 includes a contact 61 with an arc-shaped groove. The two ends of the contact 61 are fitted with conductive silicone particles 62. The bottom cover 2 is fixedly connected with an insert nut 63. A screw 64 connected to the insert nut 63 is slidably connected in the arc-shaped groove of the contact 61.

[0033] Using the technical solution of this embodiment, the contact structure 6 is used to test the test points in different ranges. The contact 61 has an arc-shaped groove 61, which allows the screw 64 to slide in the arc-shaped groove of the contact 61 when the position of the contact 61 changes, thereby changing the position of the contact 61. When it is necessary to adjust the angle of the contact 61 to test the test points in different ranges, the screw 64 can be loosened for adjustment. After adjustment, the screw 64 and the insert nut 63 are fixed to fix the contact 61. The conductive silicone particles 62 connected to the contact 61 transmit the signal obtained by the conductive silicone particles 62 to the motherboard 4.

[0034] Reference Figure 3-5The bottom cover 2 has an arc-shaped relief groove for conductive silicone particles 62. A positioning block 65 for positioning screw 64 is fixedly connected to the outside of the insert nut 63 on the bottom cover 2. In this embodiment, when the position of the contact piece 61 is changed, the conductive silicone particles 62 slide in the arc-shaped groove. The arc-shaped groove serves to make way for the conductive silicone particles 62, and the positioning block 65 is used to prevent the screw 64 from shifting.

[0035] Reference Figure 2 and Figure 4 The bottom cover 2 has an accessory compartment 21 located below the battery 5. A sliding cover 22 for the accessory compartment 21 is located on the outer side of the bottom cover 2. The bottom cover 2 has a positioning groove, and a protrusion 23 matching the positioning groove is fixedly connected to the sliding cover 22. When the sliding cover 22 is slid downwards, the protrusion 23 separates from the positioning groove. In this embodiment, the accessory compartment 21 is used to store spare conductive silicone particles. When the conductive silicone particles 62 on the contact piece 61 are lost or worn, spare particles can be taken out from the accessory compartment for replacement. The sliding cover 22 is used to seal the conductive silicone particles. When the sliding cover 22 is slid downwards, the protrusion 23 slides out of the positioning groove of the bottom cover 22, allowing the sliding cover 22 to slide out and the conductive silicone particles 62 to be removed.

[0036] Reference Figure 2 The upper part of the mainboard 4 is provided with a telephone jack socket 41 for connecting a telephone plug cable. In this embodiment, the telephone plug cable can be used to connect to the test point outside the device, achieving the same function as the contact piece 61.

[0037] Reference Figure 2 The motherboard 4 has two through holes on its upper part, which are connected to screws 64. In this embodiment, the motherboard 4 is fixed to the insert nut 63 by screws 64. In addition to fixing, screws 64 also conduct electricity, so that the motherboard 4 can obtain the information obtained by the conductive silicone particles 62.

[0038] The motherboard 4 has an indicator light at its lower part, and the cover 1 has a recessed hole for the indicator light at the corresponding position. In this embodiment, because the adhesive thickness at the recessed hole is relatively thin, the indicator light can pass through the thin wall and be displayed, while the thicker walls of the other parts of the cover cannot transmit light. The effect viewed from the outside of the cover will be a dot-shaped indicator light displayed on a flat plane.

[0039] Reference Figure 2-3 The motherboard 4 has a round hole, and a cylinder 311 is fixedly connected to the back of the button 31 at the corresponding position of the round hole. In this embodiment, the cylinder 311 is used for button positioning, avoiding the button mounting surface from affecting the button feel and performance.

[0040] Reference Figure 2The bottom cover 2 has an arc-shaped ear-shaped loop hole for threading rope, and an arc-shaped inclined rib 24 is provided inside the loop hole of the bottom cover 2. The arc-shaped inclined rib 24 is used to guide the hanging rope and guide the hanging rope to the middle position of the rope winding center column.

[0041] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
