Both the first and second fixing sleeves have arc-shaped sloping petals on their outer periphery, and threaded sleeves are fitted around the arc-shaped sloping petals of both the first and second fixing sleeves. A magnetic shielding ring is fixedly fitted onto the wire harness sleeve at one end of the second fixing sleeve.

It is convenient and flexible to use, allowing personnel to easily add or replace electronic wire harnesses requiring protection at any time, and has high practicality.

[0003] In the prior art, including the aforementioned patents, electronic wire harnesses play a crucial role in transmitting electrical energy and signals in electronic devices, and their reliability directly affects the normal operation of these devices. In practical applications, electronic wire harnesses may experience open circuit faults due to various reasons (such as external pulling or aging). Traditional electronic wire harnesses often lack open circuit detection capabilities. Once an open circuit occurs, maintenance personnel struggle to quickly and accurately pinpoint the fault location, increasing maintenance time and costs, and potentially leading to prolonged equipment downtime, impacting production and usage. Therefore, developing an electronic wire harness capable of real-time open circuit fault detection is of significant practical importance. Utility Model Content

[0004] The purpose of this invention is to provide an electronic wire harness with open circuit detection function to solve the problem of timely detection of open circuit faults mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electronic wire harness with open circuit detection function, comprising a housing, a connection terminal installed inside the housing, a wire harness body fixedly connected to one end of the connection terminal, an open circuit detection component fixedly connected to one end of the wire harness body, a plug snapped into one end of the housing, a micro-motion sensor fixedly connected to the inner wall of the plug, an LED bead installed at one end of the micro-motion sensor, and a splitter socket provided at the other end of the wire harness body.

[0006] Furthermore, the wire harness body includes an insulating outer sheath, a single-wire aluminum tube, a copper conductor, and an internal conductor. One end of the connecting terminal is fixedly connected to the insulating outer sheath. The single-wire aluminum tube is disposed inside the insulating outer sheath. The copper conductor is disposed inside the single-wire aluminum tube. The internal conductor is disposed inside the single-wire aluminum tube.

[0007] Furthermore, the connection method between the connecting terminal and the insulating outer casing is heat shrink tubing connection, the inner wall of the single-wire aluminum tube is provided with an anti-oxidation coating, the anti-oxidation coating is a nano titanium dioxide coating, and a buffer layer is provided between the single-wire aluminum tube and the copper guide wire, the buffer layer is polyurethane foam.

[0008] Furthermore, the copper conductor is made of multiple thin copper wires twisted together, with a twist pitch of 8-12 times the diameter of the copper wire, and the outer surface of the built-in conductor is wrapped with a fluororubber insulation layer.

[0009] Furthermore, the circuit breaker detection component includes a suspended wire, an elastic metal sheet, and a piezoelectric ceramic block. The outer wall of the micro-motion sensing sheet is fixedly connected to the elastic metal sheet, one end of the elastic metal sheet is fixedly connected to the piezoelectric ceramic block, and one end of the piezoelectric ceramic block is fixedly connected to the suspended wire.

[0010] Furthermore, the piezoelectric ceramic block and the suspended wire are connected by silver paste sintering, the suspended wire is made of nickel-chromium alloy wire, and the elastic metal sheet is made of beryllium bronze.

[0011] Furthermore, the lamp bead is a tri-color LED, the micro-motion sensing sheet is a beryllium copper alloy sheet, and the engaging structure between the plug and the housing includes an annular groove on the outer wall of the housing and an elastic buckle on the inner wall of the plug.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the electronic wire harness with open circuit detection function is reasonable and has the following advantages:

[0013] (1) The circuit break detection component built into this electronic wire harness adopts an innovative composite sensing structure, which consists of a suspended wire, an elastic metal sheet and a piezoelectric ceramic block to form a three-level response mechanism. When the electronic wire harness is broken due to external force pulling, insulation layer aging and other factors, the electric field around the suspended wire will be distorted instantly. This change is transmitted to the elastic metal sheet through the electric field coupling effect. The elastic metal sheet, as a high-sensitivity sensing element, produces a small deformation under the action of electric field force. Its deformation energy is transmitted to the piezoelectric ceramic block through the rigid connection structure. Based on the principle of positive piezoelectric effect, the piezoelectric ceramic block converts mechanical stress into an electrical signal pulse. This pulse signal is transmitted to the integrated control module through the shielded cable, triggering the fast response mechanism of the micro-motion sensing sheet. At this time, the three-color LED beads installed at the wire harness terminal immediately switch to the red warning mode. Compared with the traditional multimeter detection efficiency, it effectively avoids the equipment idle loss caused by the delay in fault location and significantly reduces the cost of unplanned downtime in industrial production.

[0014] (2) Through the design of the wire harness body, the copper conductor wire is made of multiple fine copper wires twisted together at a pitch of 8-12 times the diameter, which effectively improves flexibility and conductivity, reduces resistance, reduces power transmission loss, and can effectively prevent copper wire breakage in the case of frequent bending and stretching, ensuring stable signal and power transmission; the fluororubber insulation layer wrapped around the internal conductor has excellent insulation, high temperature resistance and corrosion resistance, ensuring that the internal conductor works normally in complex environments and improving the reliability of the wire harness. At the same time, the nano titanium dioxide anti-oxidation coating on the inner wall of the single-wire aluminum tube can effectively resist oxidation corrosion and slow down the aging rate of the aluminum tube; the polyurethane sponge buffer layer between the single-wire aluminum tube and the copper conductor wire can absorb external impact force and protect the copper wire from mechanical damage; the connection terminal and the insulation outer casing are connected by heat shrink tubing, which has strong sealing performance and prevents external moisture and dust from entering. The multiple protection design significantly extends the service life of the electronic wire harness and reduces the replacement cost and maintenance frequency caused by wire harness damage.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0023] Example 1:

[0024] An electronic wire harness with open circuit detection function includes a housing 1, a connection terminal 2 installed inside the housing 1, a wire harness body 3 fixedly connected to one end of the connection terminal 2, an open circuit detection component 4 fixedly connected to one end of the wire harness body 3, a plug 5 snapped onto one end of the housing 1, a micro-motion sensor 6 fixedly connected to the inner wall of the plug 5, an LED bead 7 installed at one end of the micro-motion sensor 6, and a splitter 8 provided at the other end of the wire harness body 3.

[0025] The above-described structure connects the assembled electronic wiring harness to the electronic device using the correct electrical connection method. Then, turn on the electronic device and observe the display status of LED 7. If LED 7 displays green, it indicates that the electronic wiring harness is working normally; if LED 7 displays red, it indicates that the electronic wiring harness has an open circuit fault. In this case, the user can inspect and repair the electronic wiring harness according to the actual situation to ensure the normal operation of the electronic device.

[0026] Furthermore, the wire harness body 3 includes an insulating outer sheath 301, a single-wire aluminum tube 302, a copper conductor 303, and an internal conductor 304. One end of the connecting terminal 2 is fixedly connected to the insulating outer sheath 301. The single-wire aluminum tube 302 is installed inside the insulating outer sheath 301. The copper conductor 303 is installed inside the single-wire aluminum tube 302. The internal conductor 304 is installed inside the single-wire aluminum tube 302. The connecting terminal 2 and the insulating outer sheath 301 are fixedly connected by heat shrink tubing. The inner wall of the single-wire aluminum tube 302 is provided with an anti-oxidation coating, which is a nano-titanium dioxide coating. A buffer layer is provided between the single-wire aluminum tube 302 and the copper conductor 303. The buffer layer is polyurethane foam. The copper conductor 303 is made of multiple thin copper wires twisted together, with a twist pitch of 8-12 times the diameter of the copper wire. The outer surface of the internal conductor 304 is wrapped with a fluororubber insulation layer.

[0027] The above structure securely connects one end of the fabricated wire harness body 3 to the connecting terminal 2 by means of heat shrink tubing, ensuring a firm connection and stable electrical connection. The circuit breaker detection component 4 is fixedly connected to the other end of the wire harness body 3, ensuring accurate connection position and normal collaborative operation of all components.

[0028] Furthermore, the circuit breaker detection component 4 includes a suspended wire 401, an elastic metal sheet 402, and a piezoelectric ceramic block 403. The outer wall of the micro-motion sensing sheet 6 is fixedly connected to the elastic metal sheet 402. One end of the elastic metal sheet 402 is fixedly connected to the piezoelectric ceramic block 403, and one end of the piezoelectric ceramic block 403 is fixedly connected to the suspended wire 401. The piezoelectric ceramic block 403 and the suspended wire 401 are connected by silver paste sintering. The suspended wire 401 is made of nickel-chromium alloy wire, and the elastic metal sheet 402 is made of beryllium bronze.

[0029] The above structure is achieved by fixing one end of the beryllium bronze elastic metal sheet 402 to the piezoelectric ceramic block 403 by welding or other suitable connection methods, and using silver paste to sinter the piezoelectric ceramic block 403 to the suspended wire 401 made of nickel-chromium alloy wire, ensuring that the connection is firm and has good conductivity, thus completing the assembly of the circuit breaker detection component 4.

[0030] Furthermore, the LED bead 7 is a tri-color LED, the micro-motion sensor 6 is a beryllium copper alloy sheet, and the engaging structure between the plug 5 and the outer shell 1 includes an annular groove on the outer wall of the outer shell 1 and an elastic buckle on the inner wall of the plug 5.

[0031] The above structure is achieved by fixing a micro-motion sensor 6 made of beryllium copper alloy sheet to the inner wall of plug 5, and installing a tri-color LED bead 7 at one end of the micro-motion sensor 6 to ensure normal electrical connection between the LED bead 7 and the micro-motion sensor 6. Plug 5 is then connected to housing 1 by the engagement structure of the annular groove on the outer wall of housing 1 and the elastic snap on the inner wall of plug 5. The engagement is checked to ensure it is tight and reliable. A branch connector 8 is installed at the other end of the wire harness body 3. The wiring is then rationally allocated according to actual usage requirements, completing the assembly of the entire electronic wire harness with open circuit detection function.

[0032] Working principle: When in use, firstly, when the electronic wire harness is working normally, the current is stably transmitted through the copper conductor 303 and the built-in wire 304 in the wire harness body 3. At this time, the elastic metal sheet 402 in the circuit breaker detection component 4 is in the initial state and will not undergo obvious deformation, so it cannot trigger the micro-motion sensor 6. The LED bead 7 displays green, indicating that the electronic wire harness is working normally.

[0033] Secondly, when the wire harness body 3 is open-circuited, the current transmission in the circuit is interrupted, causing the electric field near the open-circuit location to change. This change in electric field will cause the elastic metal sheet 402 to undergo elastic deformation under the action of the electric field force. The deformation of the elastic metal sheet 402 pushes the piezoelectric ceramic block 403. When the piezoelectric ceramic block 403 is subjected to external force, it generates the piezoelectric effect, converting mechanical energy into electrical energy, thereby generating an electrical signal on the suspended wire 401.

[0034] Finally, the electrical signal is transmitted to the micro-motion sensor 6, which triggers the micro-motion sensor 6 to deform, thereby causing the LED bead 7 connected to one end of the micro-motion sensor 6 to light up a red light, thus sending a warning signal to the user that there is an open circuit fault in the electronic wiring harness, so that the user can quickly locate the fault and carry out repairs.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
