[0002] A lead wire is a cable used to transmit data signals on mechanical devices. One end of the lead wire is connected to the object being measured and the other end is connected to the display device. It is the main medium for data transmission and is usually made of materials such as metal wire, alloy and fiber.
[0003] When connecting existing lead wires, most of them are to plug the plug into the jack, the plug is plugged into the jack, the probe in the jack enters the probe sleeve inside the plug, and a slot is provided inside the jack, two sets of reeds are provided in the slot, and the plug has a cylindrical structure. During processing, if the size of the probe sleeve is larger than the probe, the probe is likely to shake in the probe sleeve, and the jack needs to be tightly connected to the plug, otherwise the reed is not easy to contact the plug, resulting in unstable or even disconnected signals. If the size of the jack is smaller than the plug, the plug will not be able to enter the inside of the jack, which requires high processing accuracy and is not convenient for production and manufacturing.
[0004] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:
[0007] The utility model is a lead wire device for data signal transmission, comprising a shell, a first connecting component is fixedly connected to the inside of the shell, a conductive component is arranged inside the first connecting component, a second connecting component is arranged on the outer surface of the first connecting component, a telescopic component is arranged on the outer surface of the conductive component, the first connecting component is used to be plugged with the second connecting component, the conductive component is used to connect the data signal, the telescopic component is used to push the conductive component to move, the first connecting component has a certain elasticity and has a basket-like appearance.
[0008] Furthermore, the first connection assembly includes a crown spring fixing column, the outer surface of the crown spring fixing column is threadedly connected with a screw, the crown spring fixing column is fixedly connected to the inside of the shell, and the crown spring fixing column is fixedly connected to the conductive crown spring through the screw.

[0011] Furthermore, the telescopic assembly includes a spring, a stepped hole is provided inside the crown spring fixing column, one end of the spring is fixedly connected to the side of the probe head, and the other end of the spring is fixedly connected to the inside of the stepped hole, and the friction force between the conductive crown spring and the connecting hole is greater than the thrust of the spring.
[0012] Furthermore, the conductive crown spring is made of copper-plated gold.
[0013] Furthermore, the outer surfaces of the housing and the connector are both fixedly connected with anti-slip protrusions.
[0014] The utility model has the following beneficial effects:
[0015] 1. The utility model connects the first connecting component with the second connecting component. When the first connecting component is inserted into the second connecting component, since the first connecting component has a certain elasticity, no matter the size of the second connecting component is too large or too small, the first connecting component can adapt to the second connecting component through its own elastic deformation, thereby reducing the processing accuracy requirement and facilitating production and manufacturing.

The spring generates a reverse thrust to push the probe head against the second probe. Even if the size of the plug-in hole is larger than the second probe, the probe head can still maintain a tight connection with the second probe under the pushing action of the spring, and the machining accuracy requirements for the plug-in hole and the connecting hole on the probe head are reduced, which is convenient for production and manufacturing.

DETAILED DESCRIPTION
[0027] The following will be combined with the drawings in the utility model embodiments to clearly and completely describe the technical solutions in the utility model embodiments. Obviously, the described embodiments are only part of the utility model embodiments, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0028] In the description of the present utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inside" and the like indicating orientation or positional relationship are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the utility model.
[0029] See also Figure 1-Figure 6 As shown, the utility model is a lead wire device for data signal transmission, including a shell 1, a first connecting component 2 is fixedly connected to the inside of the shell 1, a conductive component 3 is arranged inside the first connecting component 2, a second connecting component 4 is arranged on the outer surface of the first connecting component 2, a telescopic component 5 is arranged on the outer surface of the conductive component 3, the first connecting component 2 is used to be plugged with the second connecting component 4, the conductive component 3 is used to connect the data signal, the telescopic component 5 is used to push the conductive component 3 to move, the first connecting component 2 has a certain elasticity and has a basket-like appearance.
[0030] Lift the shell 1 and move the first connecting component 2 close to the second connecting component 4, plug the first connecting component 2 and the second connecting component 4, and at the same time, connect the conductive component 3 in the first connecting component 2 with the second connecting component 4 to make the signal conductive. The telescopic component 5 on the conductive component 3 can push the conductive component 3 to keep it connected with the second connecting component 4 to avoid signal instability.
[0031] The utility model connects the first connecting component 2 with the second connecting component 4. When the first connecting component 2 is inserted into the second connecting component 4, since the first connecting component 2 has a certain elasticity and the special shape of the first connecting component 2 will cause it to be squeezed by the second connecting component 4, when the first connecting component 2 faces a larger hole, it can be pushed with force to deform it and get stuck inside the second connecting component 4. When facing a smaller hole, the second connecting component 4 will squeeze the first connecting component 2. In both cases, the first connecting component 2 can be stably connected to the second connecting component 4, thereby reducing the precision requirement of the second connecting component 4 and making it easier to produce.
[0032] In one embodiment, for the above-mentioned first connecting component 2, the first connecting component 2 includes a crown spring fixing column 201, the outer surface of the crown spring fixing column 201 is threadedly connected with a screw 202, the crown spring fixing column 201 is fixedly connected to the inside of the shell 1, and the crown spring fixing column 201 is fixedly connected to a conductive crown spring 203 through the screw 202.
[0033] Insert the conductive crown spring 203 into the crown spring fixing column 201, and then tighten the screw 202 on the crown spring fixing column 201 to complete the connection between the crown spring fixing column 201 and the conductive crown spring 203. Through the connection between the screw 202 and the conductive crown spring 203, removing the screw 202 can release the limit fixation of the conductive crown spring 203, thereby facilitating the replacement of the conductive crown spring 203.
[0034] In one embodiment, for the above-mentioned conductive component 3, the conductive component 3 includes a first probe 301, the first probe 301 is slidably connected to the inside of the crown spring fixing column 201, the end of the first probe 301 is fixedly connected with a probe head 302, and the outer surface of the probe head 302 is provided with a plug hole 303.
[0035] In one embodiment, for the above-mentioned second connecting component 4, the second connecting component 4 includes a connecting head 401, a connecting hole 402 is opened inside the connecting head 401, and the connecting hole 402 is used to be plugged into the conductive crown spring 203. A second probe 403 is fixedly connected to the inside of the connecting head 401, and the second probe 403 is plugged into the probe head 302 through the plug hole 303.
[0036] When the conductive crown spring 203 is plugged into the connecting hole 402 on the connector 401, if the size of the connecting hole 402 is large, the conductive crown spring 203 can be pushed and squeezed to deform, so that it is stuck in the connecting hole 402. When the size of the connecting hole 402 is small, the conductive crown spring 203 will be squeezed to make it stuck in the connecting hole 402. After the crown spring fixing column 201 and the conductive crown spring 203 are plugged into the connector 401, the second probe 403 in the connector 401 is plugged into the plugging hole 303 on the probe head 302, and the first probe 301 is connected to the second probe 403 to realize signal transmission.
[0037] In one embodiment, for the telescopic component 5 described above, the telescopic component 5 includes a spring 501, a stepped hole 502 is opened inside the crown spring fixing column 201, one end of the spring 501 is fixedly connected to the side of the probe head 302, and the other end of the spring 501 is fixedly connected to the inside of the stepped hole 502, and the friction force between the conductive crown spring 203 and the connecting hole 402 is greater than the thrust of the spring 501.
[0038] When the probe head 302 is connected to the second probe 403, if the second probe 403 is located in the connecting hole 402 and is longer, the second probe 403 will push the probe head 302 and the first probe 301 to slide to the left, and the probe head 302 compresses the spring 501. The spring 501 generates a reverse thrust to push the probe head 302 to keep it in close contact with the second probe 403, thereby making the connection between the second probe 403 and the probe head 302 more secure.
[0039] In one embodiment, for the conductive crown spring 203 , the conductive crown spring 203 is made of copper-plated gold.
[0040] In one embodiment, for the above-mentioned housing 1 , the outer surfaces of the housing 1 and the connector 401 are both fixedly connected with anti-slip protrusions 6 .
[0041] The copper-gold-plated material of the conductive crown spring 203 has good corrosion resistance while ensuring conductivity, extending the service life. The anti-slip protrusions 6 on the housing 1 and the connector 401 can increase the friction between the hands of the staff, making it easier for the staff to make connections.
[0042] Through the above technical solution, 1. through the connection between the first connecting component 2 and the second connecting component 4, when the first connecting component 2 is inserted into the second connecting component 4, since the first connecting component 2 has a certain elasticity, no matter the size of the second connecting component 4 is too large or too small, the first connecting component 2 can adapt to the second connecting component 4 through its own elastic deformation, thereby reducing the processing accuracy requirements and facilitating production and manufacturing. 2. Through the connection between the conductive crown spring 203 and the connecting hole 402, no matter the size of the connecting hole 402 is too large or too small, the conductive crown spring 203 itself can be elastically deformed to fully contact with the connecting hole 402, thereby ensuring the stability of the connection. At the same time, when the second probe 403 in the connecting hole 402 is connected to the plug hole 302 on the probe head 302, the second probe 403 will push the probe head 302 to move, and the probe head 302 compresses the spring 501. The spring 501 generates a reverse thrust to push the probe head 302 to support the second probe 403. Even if the size of the plug hole 303 is larger than the second probe 403, the probe head 302 can still maintain a tight connection with the second probe 403 under the pushing action of the spring 501, and the machining accuracy requirements for the plug hole 303 and the connecting hole 402 on the probe head 302 are reduced, which is convenient for production and manufacturing.
