The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0030] See Figure 1 and Figure 2 The utility model discloses a multifunctional line finder. Based on the line finding function, the multifunctional line finder also has optical power detection and red light emission functions. The multifunctional line finder is introduced in detail below.

[0031] A multifunctional line finder includes a transmitter, which includes a transmitter housing 1 and a line-finding signal transmitter installed in the transmitter housing 1. When the line finder performs line-finding operations, the cable to be found is connected to the transmitter. The line-finding signal transmitter is used to generate a signal of a specific frequency and input it into the cable or line. This signal can be an audio signal or a radio frequency signal, which is used to propagate through the cable and generate an electromagnetic field at the other end of the cable or along the line. The electromagnetic field is received by a receiver, realizing the line-finding function.

[0032] In addition, the line finder of this solution also includes an optical power detector and a red light emitter installed in the transmitter housing 1. The outer wall of the transmitter housing 1 is provided with a first interface 2 for the optical power detector to receive test light and a second interface 3 for the red light emitter to project red light.

[0033] An optical power detector is a device used to measure the power in an optical signal, and its testing principle is mainly based on the detection and processing of the photoelectric effect and electrical signals. Generally, an optical power detector mainly includes a detector, a signal processor, an analog-to-digital converter, a digital processing unit, etc., and the detection principle of the optical power detector is based on the detection and processing of the photoelectric effect and electrical signals. The detector converts the received optical signal into an electrical signal, which is amplified and processed by the signal processing circuit, and then converted into a digital signal by the analog-to-digital converter. Finally, the digital processing unit analyzes and displays the result. In this solution, the power detector can be an existing power detector commonly used in the prior art or that meets the requirements of this solution. The power detector is then fixedly installed in the transmitter housing 1, and the light to be measured is received by the optical power detector through the first interface.

[0034] The red light emitter is used to generate and emit red light, and the emitted red light is emitted from the second interface 3. In this solution, by installing the red light emitter in the line finder housing, the line finder can emit red light outward, so that the line finder can be used in a wider range of fields.

[0035] In this technical solution, by installing an optical power detector and a red light emitter in the transmitter housing 1, the line finder has the functions of optical power detection and emitting red light outward, realizing the multifunctionality of the line finder, which is easy to carry and easy to use. Especially when working outdoors, the number of instruments carried can be reduced. During use, there is no need to frequently replace instruments, thereby improving work efficiency.

[0036] In this technical solution, the first interface 2 and the second interface 3 are both arranged on the top of the transmitter housing 1. According to people's usage habits, the first interface 2 and the second interface 3 are arranged on the top of the transmitter housing 1, which is convenient for using the line finder to receive the light to be measured and realize the detection of optical power. It is also convenient for the line finder to emit red light outward, which is convenient for the red light to be irradiated. It has a simple structure and is easy to operate.

[0037] In this technical solution, a transmitter baffle 4 is provided on the outer wall of the transmitter housing 1 , and both the first interface 2 and the second interface penetrate the transmitter baffle 4 .

[0038] The emitter baffle 4 realizes the installation of the first interface 2 and the second interface 3, and also realizes the isolation of light, specifically realizing the isolation to prevent light interference, so that the light to be measured or the emitted red light can only pass through the first interface 2 and the second interface 3 respectively, thereby ensuring the accuracy of detection.

[0039] In this technical solution, independent dust plugs 9 are provided in the first interface 2 and the second interface 3.
