Three rectangular grooves are formed on the inner wall at the rear side of the circular groove, and the three rectangular grooves are evenly distributed in a circumferential shape. Support seats are embedded inside the three rectangular grooves. By arranging the wire harness mechanism in the utility model, during use, only the two interface ends of the thermistor and the wires need to be inserted into the two circular grooves on the base respectively, and then the knob is rotated to quickly clamp and fix the thermistor interface and the wires to be connected.

[0005] This assembly only forms clamping through the cooperation of multiple clamping plates to respectively clamp and fix the two interface ends of the thermistor and the wires to be connected. However, the interface ends are relatively brittle, and when the thermistor or the connecting wires are collided, the connection part is easy to break, affecting the connection quality. Content of the Utility Model

[0006] The purpose of the utility model is to solve the defect that the interface ends are relatively brittle in the prior art, and when the thermistor or the connecting wires are collided, the connection part is easy to break, affecting the connection quality, and to provide a thermistor wire harness assembly.

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

On one side of the connection block, there are two limiting ends, and the limiting ends are composed of a connection sleeve and a penetrating head. The connection sleeve is sleeved on one side of the penetrating head, and the connecting wire can be clamped and fixed through the limiting ends. On the outer wall of the connection block, there is a connection frame. On one side of the connection frame, there is a protective frame. On one side of the protective frame, two pull rods are fixedly connected, and both pull rods slide through the connection frame. Through the cooperation of the protective frame and the connection frame, the thermistor can be clamped and limited.

[0009] In a possible design, a threaded head is fixedly connected to one side of the penetrating head, and a first conical clamp is fixedly connected to one side of the threaded head. An internal thread is provided on one side of the connection sleeve, and the connection sleeve is threadedly connected to the threaded head through the internal thread. When the connection sleeve and the threaded head are threadedly connected, the inner wall of the connection sleeve can clamp the first conical clamp and enable the first conical clamp to clamp the connecting wire.

[0010] In a possible design, two through grooves are provided in the connection frame, and the pull rods extend into the through grooves. A baffle is slidably connected in the through groove. A spring is fixedly connected to one side of the baffle, and one side of the pull rod is fixedly connected to one side of the baffle. The spring is sleeved on the outer wall of the pull rod and abuts against one side inner wall of the through groove. Through the thrust generated by the spring, the protective frame and the connection frame can clamp the thermistor.

[0011] In a possible design, two through holes are provided in the connection block, and the two through holes are respectively communicated with the two limiting ends, which is convenient for the connecting wire to penetrate. A second conical clamp is fixedly connected to one side of the through hole. Two insertion holes are provided in the connection block, and the second conical clamp is located in the insertion holes. Two clamping sleeves are fixedly connected in the connection frame, and the clamping sleeves penetrate through the insertion holes and are sleeved on the outer wall of the second conical clamp. The ends of the connecting wire and the ends of the thermistor can be inserted into the second conical clamp. At the same time, the inner wall of the clamping sleeve squeezes the second conical clamp, thereby clamping the ends of the connecting wire and the ends of the thermistor.

[0012] In a possible design, connection plates are provided at the top and bottom of the connection block. Arc-shaped clamping blocks are provided on the sides of the two connection plates away from each other. Two matching plates are fixedly connected to one side of the connection frame. Card slots are provided in the two matching plates, and the card slots are sleeved on the arc-shaped clamping blocks. By sleeving the card slots on the arc-shaped clamping blocks, a clamping connection can be formed to limit the connection frame and the connection block.

[0013] In a possible design, both the first conical clamp and the second conical clamp are made of rubber material and have a certain elasticity, which is convenient for clamping.

At the same time, the connection frame and the connecting block cooperate to clamp and fix the connecting wire end and the resistor end. When the specific limiting end clamps and limits the connecting wire, the connecting wire passes through the connecting sleeve and the through-head. When the connecting sleeve is connected to the threaded head through a thread, the inner wall of the connecting sleeve will clamp the first conical clamp, and then the first conical clamp clamps the connecting wire. This mechanism ensures that the connecting wire is fixed in advance. When the connecting frame and the protective frame are used in combination, the sliding of the pull rod in the connecting frame and the sliding of the baffle in the through-groove, combined with the thrust generated by the spring, The protective frame and the connecting frame can tightly clamp the thermistor to ensure its stable position. The design of the through hole and the second tapered clamp allows the connecting wire to be easily inserted and connected to the end of the thermistor. At the same time, the inner wall of the clamping sleeve forms an extrusion effect on the second tapered clamp, which can further fix the end of the connecting wire and the end of the thermistor to prevent them from loosening or falling off. The cooperation between the arc-shaped clamping block and the clamping groove realizes the connection and fixation between the connecting frame and the connecting block. The clamping groove is clamped on the arc-shaped clamping block to form a stable clamping structure, which ensures the stability of the entire assembly. The first tapered clamp and the second tapered clamp are made of rubber material, which has a certain elasticity. It is not only convenient for clamping the connecting wire and thermistor, but also can absorb and alleviate vibration or impact to a certain extent, protecting the internal electrical connection from damage.

[0017] Beneficial effects:
