[0021] like Figure 1 and Figure 2 This embodiment provides a built-in all-in-one sensor device, which is used to be built into a contact arm. The built-in all-in-one sensor device includes:

[0022] The main body 1 has a central recessed mounting groove 10. Two positioning holes 11 are symmetrically opened on both sides of the mounting groove 10. Two limiting grooves 12 are also symmetrically opened on both sides of the mounting groove 10 on the main body 1.

[0023] The built-in all-in-one sensing device of this embodiment includes a sensing and measurement component, which is detachably connected to the main body 1, thereby simplifying the convenience of disassembly and assembly.

[0024] In this embodiment, the sensing and measurement assembly includes a temperature measurement module, a depth measurement module 9, and a clamping force measurement module. The temperature measurement module contacts the contact arm to measure the temperature of the contact arm. The clamping force measurement module extends radially from both sides of the main body 1 and abuts against the contact fingers along the inner edge of the contact arm to detect the clamping force. The depth measurement module 9 is used to detect the insertion depth of the contact arm. By combining the temperature measurement module, depth measurement module 9, and clamping force measurement module into a single sensing device, installation is simplified, and the detection of the three parameters can be achieved using the same reference, thereby improving the measurement accuracy.

[0025] In this embodiment, the sensing and measurement component further includes a main control board 2, which is built into the mounting slot 10. A detection window 13 is provided on the main body 1, and the temperature measurement module is disposed in the detection window 13. The temperature measurement module is electrically connected to the main control board 2 and is a temperature sensor. Furthermore, the detection window 13 is provided with insulating thermally conductive silicone, which is in contact with the temperature measurement module and the contact arm. The temperature on the contact arm is transferred to the temperature measurement module through the insulating thermally conductive silicone, thereby realizing temperature measurement.

[0026] In this embodiment, the sensing and measurement component further includes a cover plate 3, a cap shell 4, and a battery clip 5. The cap shell 4 has a through-hole structure. The battery clip 5 is built into the cap shell 4 and extends out of the cap shell 4 at the bottom. The upper part of the cap shell 4 is set in the mounting groove 10 and the bottom passes through the main body 1. The cover plate 3 is placed on the main control board 2 and has pull buckles 30 on both sides. The cover plate 3 passes through the positioning hole 11 through the pull buckles 30 and the pull buckles 30 are snapped into the bottom of the main body 1, thereby fixing the cover plate 3, the main control board 2, the cap shell 4, and the battery clip 5 together with the main body 1.

[0027] In this embodiment, the clamping force measuring module further includes a first force transmission arm 6, a second force transmission arm 7, and a pressure sensor 8. Two symmetrically arranged limiting grooves 12 are provided radially on the main body 1. The first force transmission arm 6 and the second force transmission arm 7 are disposed on the limiting grooves 12. The pressure sensor 8 is connected to the main control board 2 and inserted into the fixing groove 40 of the cap 4. One inner end of the first force transmission arm 6 abuts against the pressure sensor 8, and the outer end engages with the contact finger on the inner edge of the contact arm. One inner end of the second force transmission arm 7 is connected to the main control board 2, and the other end abuts against the contact finger. The first force transmission arm 6 and the second force transmission arm 7... One end of the force transmission arm 7 is a force transmission plate. Since the contact finger is fitted with a clamping spring, the clamping force of the clamping spring on the contact finger pushes the first force transmission arm 6 to transmit the force to the pressure sensor 8 to achieve measurement. The design of the contact arm, contact, and clamping spring are all existing products. This embodiment will not show or describe this structure. Convection holes are opened on both sides of the contact arm. It does not form an overall closed loop. The sensor is installed in the contact arm and does not block the convection holes, so the heat dissipation is still normal. When the sensor is installed, the contact finger is clamped by the clamping force measurement module at both ends. Therefore, the sensor will not move as a whole due to the movement of the contact arm.

[0028] In this embodiment, the depth measurement module 9 is further configured as a laser sensor. The laser sensor is connected to the main control board 2 and extends from the center of the cover plate 3. When the touch arm is inserted, the insertion depth is measured by the depth measurement module 9.

[0029] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
