Description

Technical Field

[0001] This utility model relates to a protection device for sensors, and more particularly to a floating protection device suitable for sensor wire connectors. Background Technology

[0002] For existing sensors, especially monocrystalline silicon sensors, extended lead wire connectors are often used to transmit data to corresponding devices. However, existing lead wire connectors lack independent protective sleeves at their outer ends. In some integrated devices, the presence of other devices around the sensor can easily cause compression of the lead wire connectors. Furthermore, if the device has sharp structures such as heat sinks, they can easily cut the wires on the connectors, affecting data transmission. Currently, the main solution to this problem is to wrap the lead wire connectors with adhesive. However, because adhesive wrapping offers poor resistance to stress and impact, it is still susceptible to compression in integrated layouts, leading to the lead wire connectors becoming loose.

[0003] Furthermore, rigid conduits are also used for isolation and protection. However, due to the varying lengths of the wire connectors, the rigid conduits need to be cut on-site. Improper cutting not only fails to provide full coverage of the wire connectors but also easily damages the wires, rendering them unusable.

[0004] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a floating protection device suitable for sensor wire connectors, making it more valuable for industrial applications. Utility Model Content

[0033] 17 Limiting device Detailed Implementation

[0034] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0035] like Figures 1 to 4A floating protection device for sensor wire connectors includes a connecting base 1, which is unique in that a connecting channel 2 runs through the connecting base 1, facilitating the introduction of the wire after docking with the wire connector. Simultaneously, a floating guide block 153 is installed on the connecting base 1, and the floating guide block 153 has a guide channel 4 communicating with the connecting channel 2. A floating tube 5 is movably installed within the guide channel 4. This allows the extension distance of the floating tube 5 to be adjusted according to the actual length of the wire connector, ensuring the wire connector is protected by the floating tube 5. Furthermore, this invention includes several receiving cavities 6 in the floating guide block 153 that dock with the guide channel 4. A limiting device 17 is installed within the receiving cavity 6, contacting the outer wall of the floating tube 5. Thus, relying on the presence of the limiting device 17, the floating tube 5 can achieve a near-infinitely adjustable extension length within its length range, adapting to different wire connector length protection needs, and achieving positioning after extension to prevent loosening of the floating tube 5.

[0036] In a preferred embodiment of this invention, the inlet end of the connecting channel 2 of the connecting base 1 is provided with connecting threads 7. This allows for compatibility with the currently pre-set threaded rings of sensors, achieving convenient threaded connection.

[0037] Furthermore, to apply appropriate binding force, allowing the floating tube 5 to be locked after adjustment and kept stationary for extended periods without external force, the limiting device 17 includes an elastic component 8 installed within the receiving cavity 6. Simultaneously, a force-applying rod 9 is mounted on the elastic component 8, with a force-applying block at its front end, contacting the outer wall of the floating tube 5. Specifically, the elastic component 8 used in this invention is a spring, and positioning blocks 10 are distributed within the receiving cavity 6, with the tail end of the spring connected to the positioning blocks 10. This prevents excessive vibration when the spring deforms. Furthermore, a contact plate 11 extends from the tail end of the force-applying rod 9, adhering to the front end of the spring. This prevents accidental loosening of the force-applying rod 9 during assembly. To provide suitable contact damping, the force-applying block includes a mounting plate 12 connected to the force-applying rod 9, with a contact block 13 embedded in the mounting plate 12. The contact block 13 is a rubber block. Therefore, by using the rubber block to provide appropriate frictional damping, the floating tube 5 is positioned under the stress of the spring.

[0038] In practical implementation, this invention features several vertically distributed guide grooves 14 on the inner wall of the guide channel 4, and outwardly protruding guide blocks 15 at corresponding positions on the outer wall of the floating tube 5, with the guide blocks 15 embedded in the guide grooves 14. This prevents unnecessary rotation of the floating tube 5 during adjustment, achieving effective stretching and retraction guidance.

[0039] Furthermore, in order to facilitate the user to pull out the floating tube 5 when it is at its lowest position, a pull ring 16 can be installed at the upper end of the floating tube 5.

[0040] The working principle of this utility model is as follows:

[0041] The user installs the connecting base 1 of this invention onto the end of the sensor with the wire connector via a threaded connection. Then, by squeezing the pull ring 16 or touching the inner wall of the floating tube 5 with their finger, upward force is applied. Once the applied force overcomes the stress of the elastic component 8, the floating tube 5 can move upward. After the user stops applying force, the floating tube 5 is restrained by the limiting device 17 and cannot move.

[0042] This effectively protects the wire connector located inside the floating tube 5. External components will not compress the wire connector, nor will sharp parts of the equipment casing scratch it.

[0043] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0044] 1. The connecting base can directly interface with the sensor without the need for an additional adapter, resulting in better integration and reduced manufacturing costs.

[0045] 2. The floating tube has a better free adjustment stroke, which can be adjusted for the final connection length of the wire connector, ensuring that the wire connector is always surrounded and protected by the floating tube.

[0046] 3. Equipped with a limit device, the floating tube can be positioned to prevent secondary movement after it is adjusted to the correct position, thus avoiding exposure of the wire connectors. Furthermore, the limit device can be engaged by the user, providing excellent self-locking performance.

[0047] 4. By using guide grooves and guide blocks in combination, the floating tube will not tilt or rotate unnecessarily during adjustment.

[0048] 5. The overall structure is simple, suitable for various conventional single-crystal silicon sensors, and easy to use.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation.

[0050] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
