Description

Technical Field

[0001] The present application relates to the technical field of anti-static protective gear, and in particular to an intelligent anti-static ankle strap instrument. Background Art

[0002] In electronics manufacturing workshops, static electricity is a harmful interference factor that must be avoided at all costs. During the production of precision instruments and electronic equipment, static electricity can damage electronic components, and in severe cases, even render the product scrapped. Therefore, to prevent the effects of static electricity on electronic components, workers typically wear anti-static ankle straps to dissipate any static electricity generated.

[0003] Existing anti-static ankle strap devices are mainly tied to the user's calf through elastic conductive webbing, and the anti-static ankle strap device is connected to the grounding end on the sole of the foot through a grounding wire, and adheres to the calf skin through a metal contact piece to conduct static electricity.

[0004] However, although the existing elastic conductive webbing has a certain degree of tightness adjustment, its adjustment degree is limited. Moreover, after being worn for a certain period of time, the elasticity of the conductive webbing will deteriorate and it will not be able to adapt well to the changes in the size of the wearing part, causing the anti-static ankle strap instrument to become loose. Summary of the Invention

[0005] The present application provides an intelligent anti-static ankle strap instrument, which uses the principle of a spiral spring to achieve automatic expansion and contraction of a conductive ribbon. The length of the conductive ribbon is adjusted by the number of contraction turns of the spiral spring to prevent the conductive ribbon of the anti-static ankle strap instrument from loosening.

[0006] The present application provides an intelligent anti-static ankle strap device that adopts the following technical solutions:

[0007] An intelligent anti-static ankle strap instrument comprises a housing and a strap assembly mounted on the housing;

[0008] The bandage assembly includes a first conductive webbing and a second conductive webbing connected to the housing;

[0009] One end of the first conductive ribbon is inserted into the housing and connected to an adjusting member provided in the housing, and the first conductive ribbon is pulled out and retracted on the adjusting member after being pulled;

[0010] One end of the second webbing is fixedly connected to the housing;

[0011] The other end of the first conductive ribbon and the other end of the second conductive ribbon are detachably connected.

[0012] By adopting the above technical solution,

[0013] To further better implement the present application, the following configuration is particularly adopted: the adjusting member includes two fixing seats fixedly connected to the housing, a scroll spring embedded in the two fixing seats, and a reel with both ends passing through the two fixing seats, rotatably connected to the fixing seats, and fixedly connected to one end of the scroll spring;

[0014] One end of the first conductive ribbon passes through the housing and is fixedly connected to the reel, and the first conductive ribbon is wound around the reel.

[0015] By adopting the above technical solution, before use, the first conductive webbing is partially wound on the reel, and the spiral spring in the fixed seat is in a naturally relaxed state. When the intelligent anti-static ankle strap device needs to be worn on the user's calf, the first conductive webbing is pulled out of the reel, and the spiral spring is compressed. Its rebound force will cause the first conductive webbing to be pulled back. At this time, the intelligent anti-static ankle strap device is fixed to the wearer's calf by plugging and fitting the female buckle on the first conductive webbing with the male buckle on the second conductive webbing. The first conductive webbing will be naturally tightened. Even if the wearer walks and the first conductive webbing is pulled and loosened, the rebound force of the spiral spring will automatically shrink the conductive webbing and restore it to a taut state, thus effectively adapting to the changes between loose and taut conductive webbing at the wearing location.

[0016] In order to further better realize the present application, the following setting structure is particularly adopted: one end of the first conductive webbing is fixedly connected to a female buckle, and one end of the second conductive webbing is fixedly connected to a male buckle, and the male buckle is plugged into the female buckle.

[0017] By adopting the above technical solution, the first conductive ribbon and the second conductive ribbon are easily connected.

[0018] To further better implement the present application, the following configuration is particularly adopted: a conductive component is mounted on the housing;

[0019] The conductive component includes a metal contact piece and a spring ejector pin mounted on the housing; a circuit board is mounted in the housing, and the spring ejector pin is fixedly connected to the circuit board;

[0020] The shell is provided with an opening, and the end of the spring ejector pin is in contact with and connected to the metal contact piece through the opening on the shell.

[0021] By adopting the above technical solution, the metal contact piece achieves electrical connection by contacting the spring pins welded on the circuit board, without the need for soldering wires. As a result, the manufacturing and assembly processes are simpler and faster.

[0022] To further better implement the present application, the following configuration structure is particularly adopted: a receiving groove is provided on the housing, and the metal contact piece is embedded in the receiving groove.

[0023] By adopting the above technical solution, the metal contact piece can be more conveniently installed on the housing.

[0024] To further better implement the present application, the following configuration structure is particularly adopted: a protruding soft layer is provided at the edge of the receiving groove, and the soft layer clamps the metal contact piece.

[0025] By adopting the above technical solution, the soft layer clamps the metal contact piece, which enables the metal contact piece to be installed more firmly on the housing.

[0026] To further better implement the present application, the following configuration is particularly adopted: a grounding wire is connected to the housing, and a wire buffer assembly is provided on the grounding wire;

[0027] The wire buffer assembly includes an inner sleeve, an outer sleeve, and a fixing spring arranged between the inner sleeve and the outer sleeve, wherein two ends of the fixing spring are respectively connected to the inner sleeve and the outer sleeve;

[0028] The grounding wire is passed through the inner casing and the outer casing, and the grounding wire is fixedly connected to the connection between the inner casing and the outer casing;

[0029] The grounding wire is spirally wound inside the fixing spring.

[0030] By adopting the above technical solution, when the grounding wire is suddenly stretched by external force, the grounding wire first pulls the inner sleeve and the outer sleeve, causing the inner sleeve to gradually come out of the outer sleeve, and the fixed spring is in a tensioned state and gradually stretched to a taut state. The external kinetic energy is gradually converted into elastic potential energy of the fixed spring, and then the energy is gradually consumed in the reciprocating motion of the fixed spring and the inner sleeve and the outer sleeve, thereby avoiding direct impact on the connection between the intelligent anti-static ankle strap instrument interface and the wire connector.

[0031] In order to further better realize the present application, the following setting structure is particularly adopted: the soft layer is bonded to the outer shell.

[0032] By adopting the above technical solution, it is convenient to arrange the soft layer on the shell.

[0033] In summary, this application includes at least one of the following beneficial technical effects:

[0034] 1. Provide an intelligent anti-static ankle strap instrument, which uses the principle of scroll spring to realize the automatic expansion and contraction of the conductive ribbon. The length of the conductive ribbon is adjusted by the number of contraction turns of the scroll to prevent the conductive ribbon of the anti-static ankle strap instrument from loosening;

[0035] 2. Provide a metal contact sheet structure and a connection method with the circuit board, so that the metal sheet can be in contact with the circuit board after being pressed and fixed, thereby facilitating the production and assembly of the entire machine;

[0036] 3. Add multiple wire buffer structures with fixed springs to the grounding wire to convert the kinetic energy of the grounding wire when it is pulled into the elastic potential energy of the fixed spring, avoiding direct force on the wire joint and thus preventing poor contact problems at the interface.

[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0047] The present application embodiment discloses an intelligent anti-static ankle strap instrument. Figure 1 、 Figure 2 The intelligent anti-static ankle strap instrument includes a shell 1, a strap component 2 and a conductive component 3 installed on the shell 1, and a wire buffer component 4.

[0048] Reference Figure 3 The housing 1 includes an upper housing 11 and a lower housing 12, which are connected by a snap-fit ​​mechanism. Housing 1 houses a circuit board 13, a battery 14, and a light guide 15. Battery 14 is a lithium battery, and light guide 15 is an indicator light. The indicator light is exposed through upper housing 11 and displays current status information. The internal battery 14 allows current information to be wirelessly transmitted to a backend management system, allowing system administrators to keep abreast of the operating status of each smart anti-static ankle strap.

[0049] Reference Figure 3 、 Figure 4 The strap assembly 2 includes two fixing bases 21 fixedly connected to the lower shell 12. A reel 22 is provided between the two fixing bases 21. Both ends of the reel 22 are provided in the fixing bases 21. A spiral spring 23 is mounted on both ends of the reel 22. The spiral spring 23 is fixedly connected to the reel 22. The reel 22 rotates to tighten and loosen the spiral spring 23. A first conductive ribbon 24 is wound around the reel 22. The first conductive ribbon 24 extends from the lower shell 12. One end of the first conductive ribbon 24 is fixedly connected to the reel 22, facilitating the rotation of the reel 22 and the reel 22's rotation to retract the first conductive ribbon 24. The other end of the first conductive ribbon 24 is fixedly connected to a female buckle 26. A second conductive ribbon 25 is fixedly connected to the side of the lower shell 12 facing away from the first conductive ribbon 24. One end of the second conductive ribbon 25 is fixedly connected to the lower shell 12, and the other end is fixedly connected to a male buckle 27. The male buckle 27 is plugged into the female buckle 26. The fixing base 21 has a hole for accommodating the scroll spring 23.

[0050] Before use, the first conductive webbing 24 is partially wound around the reel 22, and the spiral spring 23 within the mounting base 21 is in a naturally relaxed state. When the intelligent anti-static ankle strap is worn on the user's calf, the first conductive webbing 24 is pulled out of the reel 22. The spiral spring 23 is compressed, and its resilience causes the first conductive webbing 24 to retract. At this point, the intelligent anti-static ankle strap is secured to the wearer's calf by the female buckle 26 on the first conductive webbing 24 and the male buckle 27 on the second conductive webbing 25. The first conductive webbing 24 is naturally tightened. Even if the wearer walks and the first conductive webbing 24 becomes loose due to the tension, the resilience of the spiral spring 23 automatically retracts the conductive webbing, restoring its tension. This allows the strap to adapt to changes in tension between the conductive webbing at the wearer's location.

[0051] Reference Figure 2 、 Figure 5 The conductive component 3 includes a metal contact piece 31. The metal contact piece 31 is attached to the lower shell 12. When the intelligent anti-static ankle strap device is worn on the calf, the metal contact piece 31 contacts the calf. The lower shell 12 has a receiving groove 121, and the metal contact piece 31 is embedded in the receiving groove 121.

[0052] Reference Figure 5 、 Figure 6 A spring-loaded pin 32 is fixedly connected to the circuit board 13 in the housing 1. The spring-loaded pin 32 can be connected to the circuit board 13 by welding. An opening is provided in the receiving slot 121 to expose the top of the spring-loaded pin 32. The spring-loaded pin 32 contacts the metal contact piece 31 arranged in the receiving slot 121. A protruding soft layer 16 is provided at the edge of the receiving slot 121. The soft layer 16 is used to clamp the metal contact piece 31, making the connection between the metal contact piece 31 and the lower housing 12 more secure. The soft layer 16 is part of the lower housing 12 of the intelligent anti-static ankle strap instrument and is covered on the lower housing 12 through a rubber coating process.

[0053] The outer edge of the metal contact piece 31 is flat and does not require bending. It can be directly pressed against the corresponding position on the surface of the housing 1 to secure the conductive metal contact piece 31. Furthermore, the conductive metal contact piece 31 establishes an electrical connection by contacting the spring-loaded ejector pins 32 soldered to the circuit board 13, eliminating the need for soldering wires. This simplifies and simplifies the manufacturing and assembly processes.

[0054] When the intelligent anti-static ankle strap instrument is worn on the user's foot, the grounding end must be connected through the grounding wire 5 to finally conduct the static electricity to the earth. The user is not always still during work, and the grounding wire 5 may be pulled by sudden external forces. The existing grounding wire 5 is of fixed length. When it is pulled by external force, the external force will directly act between the connector of the grounding wire 5 and the interface of the intelligent anti-static ankle strap instrument, causing the connector to be forcibly pulled out of the interface, resulting in poor contact. At this time, the intelligent anti-static ankle strap instrument loses its function of conducting static electricity, and the instrument detects an abnormality in the measured value, which triggers the instrument to sound an alarm. Therefore, in order to prevent the connector from being forcibly pulled out of the interface, a wire buffer component 4 is provided.

[0055] Reference Figure 7 、 Figure 8 The wire buffer assembly 4 includes an inner sleeve 41 and an outer sleeve 42. The inner sleeve 41 is inserted into the outer sleeve 42, so that the inner sleeve 41 and the outer sleeve 42 are plugged together. A fixing spring 43 is provided between the inner sleeve 41 and the outer sleeve 42. The two ends of the fixing spring 43 are fixedly connected to the inner sleeve 41 and the outer sleeve 42 respectively. When the fixing spring 43 is in a naturally contracted state, the inner sleeve 41 and the outer sleeve 42 are at their shortest total length. When the inner sleeve 41 and the outer sleeve 42 are pulled, the inner sleeve 41 gradually comes out of the outer sleeve 42, and the fixing spring 43 is in a tensioned state. The fixing spring 43 can be connected to the inner sleeve 41 and the outer sleeve 42 by a snap-fit ​​method. Furthermore, clamping rings that can be clamped to each other are provided at the ends of the inner sleeve 41 and the outer sleeve 42 to prevent the inner sleeve 41 and the outer sleeve 42 from being completely separated due to excessive pulling.

[0056] The grounding wire 5 is passed through the inner sleeve 41 and the outer sleeve 42 and is fixedly connected to the connection between the inner sleeve 41 and the outer sleeve 42. The grounding wire 5 is spirally wound inside the fixing spring 43.

[0057] In its natural state, the fixed spring 43 inside the wire buffer assembly 4 structure is in a naturally contracted state, the fixed spring 43 is not under stress, and the grounding wire 5 inside the fixed spring 43 is also in a spirally contracted state. When the grounding wire 5 is suddenly stretched by an external force, the grounding wire 5 first pulls the inner sleeve 41 and the outer sleeve 42, causing the inner sleeve 41 to gradually come out of the outer sleeve 42. The fixed spring 43 is in a tensioned state and gradually stretches to a taut state until the inner sleeve 41 and the outer sleeve 42 reach a limited position and stop stretching. The spiral bundle of the grounding wire 5 inside the fixed spring 43 straightens. Due to the limit of the inner sleeve 41 and the outer sleeve 42, the spiral bundle of the grounding wire 5 is in a naturally straightened state without stress, preventing the connector of the grounding wire 5 and the interface of the intelligent anti-static ankle strap instrument from being directly pulled. At this time, the external kinetic energy is gradually converted into the elastic potential energy of the fixed spring 43, and then the energy is gradually consumed in the reciprocating motion of the fixed spring 43, the inner sleeve 41 and the outer sleeve 42, thereby avoiding direct impact on the connection between the instrument interface of the smart anti-static ankle strap and the wire connector.

[0058] The implementation principle of an intelligent anti-static ankle strap instrument in an embodiment of the present application is as follows: the principle of a spiral spring 23 is used to realize automatic expansion and contraction of the first conductive ribbon 24, and the length of the conductive ribbon is adjusted by the number of contraction turns of the spiral spring 23 to prevent the conductive ribbon of the anti-static ankle strap instrument from loosening; a plurality of wire buffer components 4 with fixed springs 43 are added to the grounding wire 5 to convert the kinetic energy of the wire when it is pulled into the elastic potential energy of the spring, thereby avoiding direct force on the wire joint, thereby preventing poor contact problems in the interface; the metal contact piece 31 is abutted against the spring pin 32, so that the metal contact piece 31 can be in contact with the circuit board after being pressed and fixed, thereby facilitating the production and assembly of the entire machine.

[0059] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
