Description

Technical Field

[0001] This application relates to the field of circuit protection, and in particular to a grounding plate and grounding device. Background Technology

[0002] Grounding is a crucial way to ensure stable circuit operation. When a grounding point on a circuit board is connected to the ground potential, interference signals, noise, and static charges can be effectively eliminated, thus ensuring the normal operation of the circuit board. At the same time, grounding electrical equipment increases its safety and reduces the risk of electric shock damage. A grounding plate is a specific form of grounding. When a problem occurs inside a component, the grounding plate can quickly short-circuit, allowing current to flow to the ground and eliminating the fault, thereby ensuring the safety performance of the equipment. Simultaneously, the grounding plate can also protect components on the circuit board. When components on the circuit board are affected by static electricity, capacitors easily collect static energy, leading to short circuits or even damage. In this case, the grounding plate can carry the static charge back to the ground, thus protecting the components.

[0003] In the existing technology, grounding plates are usually connected to the circuit board and grounding point by soldering. This grounding method is complicated to operate and the grounding plates are not easy to replace. Utility Model Content

[0057] Please refer to the attached document. Figure 1As shown, the grounding plate 10 of this application has a first grounding point 110 and a second grounding point 120 provided on the grounding body 100 for grounding connection with the first grounding element and the second grounding element. The first grounding point 110 refers to the connection point between the first grounding element and the grounding body 100, and the second grounding point 120 refers to the connection point between the second grounding element and the grounding body 100.

[0058] In one embodiment, the first grounding point 110 and the second grounding point 120 are arranged at intervals along the first direction X on the grounding body 100.

[0059] Please refer to the attached document. Figure 1 As shown, the grounding piece 10 of this application includes a limiting structure 200. The grounding body 100 uses the limiting structure 200 to fix the relative position between the grounding piece 10 and the first grounding element 20 and the second grounding element 30. The limiting structure 200 is at least disposed at one end of the grounding body 100 along the third direction Z, and the limiting structure 200 is connected to the grounding body 100. In this application, the two ends of the grounding body 100 along the third direction Z are the upper end and the lower end of the grounding body 100, respectively. The limiting structure 200 being at least disposed at one end of the grounding body 100 along the third direction Z means that the upper end and / or the lower end of the grounding body 100 are provided with the limiting structure 200 to fix the relative position between the grounding piece 10 and the first grounding element 20 and the second grounding element 30.

[0060] In one embodiment, a limiting structure 200 is provided at the upper end of the grounding body 100 along the third direction Z.

[0061] Please refer to the attached document. Figure 1 As shown, the limiting structure 200 of this application includes a first limiting member 210 and a second limiting member 220. The first limiting member 210 is used to limit the grounding sheet 10 body and the first grounding member and the second grounding member in the second direction Y. The second limiting member 220 is used to limit the grounding body 100 and the first grounding member and the second grounding member in the first direction X.

[0062] The first limiting member 210 is at least disposed on one side of the grounding body 100 along the first direction X, and extends along the first direction X. In this application, the two sides of the grounding body 100 along the first direction X refer to the front and rear sides of the grounding body 100, respectively. The first limiting member 210 being at least disposed on one side of the grounding body 100 along the first direction X means that the first limiting member 210 is disposed on the front and / or rear side of the grounding body 100, and extends along the first direction X to limit the grounding piece 10 and the first grounding member and the second grounding member in the second direction Y.

[0063] In one embodiment, the grounding body 100 is provided with a first limiting member 210 on both the front and rear sides along the first direction X.

[0064] The second limiting member 220 is at least disposed on one side of the grounding body 100 along the second direction Y, and extends along the second direction Y. In this application, the two sides of the grounding body 100 along the second direction Y refer to the left and right sides of the grounding body 100, respectively. The second limiting member 220 being at least disposed on one side of the grounding body 100 along the second direction Y means that the second limiting member 220 is disposed on the left and / or right sides of the grounding body 100, and extends along the second direction Y to achieve limiting between the grounding piece 10 and the first grounding member and the second grounding member in the first direction X.

[0065] Please refer to the attached document. Figure 1 As shown, the limiting structure 200 of this application is provided with a snap-fit ​​tab 230. The snap-fit ​​tab 230 is elastically connected to the limiting structure 200 under the action of external force, and the snap-fit ​​tab 230 protrudes from the limiting structure 200. When the grounding piece 10 is installed, the limiting structure 200 and the snap-fit ​​tab 230 enter the object to be installed together. Under the action of the object to be installed, the snap-fit ​​tab 230 retracts inward and approaches the limiting structure 200. The snap-fit ​​tab 230 abuts against the object to be installed to lock the relative position of the grounding piece 10.

[0066] In one embodiment, the second limiting member 220 is provided with a snap-fit ​​piece 230.

[0067] In one embodiment, a movable hole 240 is provided at the corresponding position of the limiting structure 200 and the snap-fit ​​piece 230, so that the snap-fit ​​piece 230 can partially enter the movable hole 240 when it moves toward the limiting structure 200, thereby increasing the contraction range of the snap-fit ​​piece 230 and further enhancing the preload of the snap-fit ​​piece 230.

[0068] Please refer to the attached document. Figure 1As shown, the first grounding point 110 of this application has a receiving cavity recessed in the third direction Z. The opening of the receiving cavity is disposed towards the first grounding member. The first grounding member and the first grounding point 110 are connected by an elastic member. One end of the elastic member abuts against the first grounding member, and the second end of the elastic member is located in the receiving cavity. The arrangement of the receiving cavity can further prevent the movement of the elastic member, thereby enhancing the stability of the connection between the first grounding point 110 and the first grounding member.

[0069] Please refer to the attached document. Figure 1 As shown, the second grounding point 120 of this application is provided with a first connecting hole 121 through the third direction Z. The second grounding component and the second grounding point 120 are connected by a fastener 500. After the fastener 500 passes through the first connecting hole 121, it is fixedly connected to the second grounding component so as to connect the grounding piece 10 and the second grounding component in series.

[0070] In one embodiment, the first connecting hole 121 has a circular structure.

[0071] When the second grounding component is not used for a long time, an oxide layer will form on its surface, which will affect the stability of the electrical connection between the second connection and the second grounding component. Therefore, a protruding tooth 130 is further provided.

[0072] Please refer to the attached document. Figure 1 As shown, the protruding teeth 130 of this application are disposed within the first connecting hole 121 and connected to the second grounding point 120. The first end of the protruding teeth 130 is connected to the surface of the first connecting hole 121, and the second end of the protruding teeth 130 extends into the first connecting hole 121. Furthermore, the protruding teeth 130 are circumferentially spaced within the first connecting hole 121. After the fastener 500 passes through the first connecting hole 121, it acts on the surface of the protruding teeth 130 and drives the protruding teeth 130 to move towards the second grounding component. After contacting the surface of the second grounding component, the protruding teeth 130 disrupt the oxide layer on the surface of the second grounding component, thereby achieving direct contact between the protruding teeth 130 and the conductive layer within the second grounding component, thus enhancing the stability of the electrical connection between the second connecting point and the second grounding component. In this application, the bottom of the oxide layer of the second grounding component is a conductive layer. If the second grounding component is metal, the oxide layer is composed of its metal oxide, and the conductive layer is composed of its metal. Furthermore, multiple protrusions 130 are provided in the first connection hole 121. The grounding piece 10 forms a ground with the second grounding component through the protrusions 130. If individual protrusions 130 are corroded or oxidized during use, causing grounding failure, or if individual protrusions 130 fail to form an effective ground due to uneven surface at the second grounding point during installation, the grounding piece 10 can still achieve grounding connection with the second grounding component through other protrusions 130.

[0073] In one embodiment, the protruding tooth 130 is flush with the grounding body 100 in the initial state or protrudes from the surface of the grounding body 100, and in the initial state, the protruding direction of the protruding tooth 130 is away from the second grounding member. In the use state, the protruding tooth 130 protrudes from the surface of the grounding body 100, and in the use state, the protruding tooth 130 is close to the second grounding member.

[0074] Example 2

[0075] Please refer to the attached document. Figure 2 To be continued Figure 6 As shown, a specific embodiment of the grounding device of this application is illustrated. The grounding device of this application is used for grounding connection between the first grounding component 20 and the second grounding component 30, so as to transfer the electrostatic charge in the first grounding component 20 to the ground through the second grounding component 30, thereby ensuring the normal operation of the circuit board and further enhancing the safety of electrical equipment. In this application, the connection between the grounding piece 10 and the first grounding component 20 and the second grounding component 30 is a detachable connection, so that the grounding piece 10 can be replaced after damage. Furthermore, the detachable grounding method between the grounding piece 10 and the first and second grounding components facilitates the mechanized assembly of the grounding piece 10 with the first and second grounding components. If the grounding piece 10 is connected to the first and second grounding components by welding or other methods, automated welding is not easily achieved due to the concealed nature of the connection points between the grounding piece 10 and the first and second grounding components.

[0076] Please refer to the attached document. Figure 2 and appendix Figure 3 As shown, the first direction in this application refers to the length direction of the grounding device, that is, the direction from left to right or from right to left. In this application, the first grounding element 20 is positioned to the left of the second grounding element 30, and the second grounding element 30 is positioned to the right of the first grounding element 20. The third direction Z in this application refers to the height direction of the grounding device, that is, the direction from top to bottom or from bottom to top. In the grounding device, the fastener 500 is positioned higher than the second grounding element 30, and the second grounding element 30 is positioned lower than the fastener 500.

[0077] Appendix Figure 2 This is a schematic diagram of one possible structure of the grounding device described in this application. Please refer to the attached diagram. Figure 2As shown, the grounding device of this application includes a grounding piece 10, which is used for grounding connection between the first grounding member 20 and the second grounding member 30. The grounding piece 10 is detachably connected to the first grounding member 20 and the second grounding member 30, and the detachable connection between the grounding piece 10 and the first grounding member 20 and the second grounding member 30 will be further described in subsequent drawings. The specific structure of the grounding piece 10 of this application has been described in Embodiment 1, and will not be further described in this embodiment.

[0078] Please refer to the attached document. Figure 2 As shown, the grounding device of this application also includes a cover 400 and a fastener 500. The cover 400 and the fastener 500 are arranged sequentially along the third direction Z, and the fastener 500 is partially located inside the cover 400. After the grounding piece 10 is placed inside the cover 400, the cover 400 is placed on the first grounding member 20 and the second grounding member 30 to achieve a stable connection between the grounding piece 10 and the first grounding member 20 and the second grounding member 30, and to further prevent the grounding piece 10 from being exposed. A limiting groove 420 is provided inside the cover 400. The limiting structure 200 includes a first limiting member 210 and a second limiting member 220. The first limiting member 210 and the second limiting member 220 are disposed in the limiting groove 420 to limit the grounding piece 10 and the cover 400 in the first direction X and the second direction Y, and at the same time realize the snap-fit ​​between the limiting structure 200 and the cover 400, and further form the limiting of the grounding piece 10 and the cover 400 in the third direction Z.

[0079] The cover 400 has a second connecting hole 410 through it in the third direction Z. The second connecting hole 410 is corresponding to the first connecting hole 121. The fastener 500 enters the first connecting hole 121 through the second connecting hole 410 and connects to the second grounding component 30 to fix the cover 400 on the second grounding component 30. At the same time, the grounding piece 10 is connected to the second grounding piece 10. This fixing method can not only fix the grounding piece 10 stably on the second grounding component 30, but also realize the detachable connection of the cover, the grounding piece 10 and the second grounding component 30.

[0080] Please refer to the attached document. Figure 2As shown, the grounding device of this application also includes an abutment ring 600, which is configured to drive the protruding teeth 130 to move toward the second grounding member 30. The abutment ring 600 has a third connecting hole 510 extending through it in a third direction Z. The third connecting hole 510 corresponds to the first connecting hole 121. The abutment ring 600 is located within the second connecting hole 410 and between the second connection point and the fastener 500. The fastener 500 sequentially drives the third connecting hole 510 and the first connecting hole 121 and connects to the second grounding member 30. When the fastener 500 moves toward the second grounding member 30, the abutment ring 600 drives the protruding teeth 130 to move toward the second grounding member 30, thereby damaging the surface of the second grounding member 30.

[0081] Please refer to the attached document. Figure 2 As shown, the grounding device of this application further includes an elastic element 300, and the first grounding point 110 is connected to the first grounding element 20 through the elastic element 300. Furthermore, the elastic element 300 is connected to both the first grounding element 20 and the first grounding point 110. The connection between the elastic element 300 and the first grounding element 20 is a fixed connection, and the connection between the elastic element 300 and the first grounding point 110 is an abutment connection.

[0082] Appendix Figure 3 This is a cross-sectional view of the grounding device described in this application. Please refer to the attached diagram. Figure 3 As shown, the first grounding member 20 of this application has a first abutting surface 21 on the side near the cover 400. The first abutting surface 21 of the first grounding member 20 abuts against the first grounding point of the grounding body 100 through an elastic member 300. The elastic member 300 includes an elastic body 310 and a fixing frame 320. The first end of the elastic body 310 along the third direction Z is connected to the fixing frame 320 to achieve a stable connection of the elastic body 310. The second end of the elastic body 310 along the third direction Z abuts against the first grounding point 110. The fixing frame 320 is fixed on the first abutting surface 21. Both the elastic body 310 and the fixing frame 320 are made of conductive material to achieve an electrical connection between the first grounding member 20 and the first grounding point 110. Furthermore, when it is necessary to connect the first grounding point 110 of the grounding piece 10 with the first grounding member 20, the cover plate with the grounding piece 10 is simply placed over the first grounding member 20, achieving abutment between the elastic body 310 and the first grounding point 110. When it is necessary to separate the elastic element 300 from the grounding piece 10, the cover 400 can be removed directly to remove the grounding piece 10 from the surface of the elastic element 300. Therefore, the connection between the elastic element 300 and the first grounding point 110 in this application is easy to install and remove, and can be easily automated.

[0083] Please refer to the attached document. Figure 3The second grounding point 120 of this application has a second abutment surface 31 on the side near the cover plate. The second abutment surface 31 of the second grounding member 30 is directly connected to the second grounding point 120 of the grounding plate 10 under the connection of the fastener 500. The fastener 500 includes a screw head 510 and a screw rod 520 arranged along the third direction Z. One end of the screw rod 520 is fixedly connected to the screw head 510. The second connecting hole 410 includes an upper connecting hole 411 and a lower connecting hole 412 arranged sequentially along the third direction Z. The cross-sectional area of ​​the upper connecting hole 411 in the first direction X is larger than the cross-sectional area of ​​the lower connecting hole 412 and the screw head 510 in the first direction X. The cross-sectional area of ​​the lower connecting hole 412 in the first direction X is smaller than the cross-sectional area of ​​the screw head 510 in the first direction X. The cross-sectional area of ​​the lower connecting hole 412 in the first direction X is larger than the cross-sectional area of ​​the screw rod 520 in the first direction X. That is, the screw 520 can move automatically within the upper connecting hole 411 and the lower connecting hole 412, while the screw head 510 can only move freely within the upper connecting hole 411 and cannot enter the lower connecting hole 412. In this application, the height of the abutment ring 600 in the third direction Z is greater than the height of the lower connecting hole 412 in the third direction Z. After the limiting structure 200 of the grounding piece 10 is installed in the limiting groove 420, the grounding piece 10 is located at the bottom of the cover 400; then the abutment ring 600 is placed in the lower connecting hole 412, at which time the first end of the abutment ring 600 is located in the upper connecting hole 411, and the second end of the abutment ring 600 abuts against the protrusion 130; then the fastener 500 is passed through the abutment ring 600 in the second connecting hole 410 and the first connecting hole 121 in sequence and connected to the connecting thread in the second grounding member. When the fastener 500 is tightened downwards, it drives the abutment ring 600 to move toward the protrusion 130, and further drives the protrusion 130 to move toward the second abutment surface 31 of the second grounding member 30, until the cover 400 and the second grounding member 30 are fixed. At this time, the protrusion 130 destroys the oxide layer on the surface of the second grounding member 30, and the second grounding point 120 of the grounding piece 10 is directly electrically connected to the second grounding member 30 through the protrusion 130. When it is necessary to separate the second grounding element 30 from the grounding piece 10, simply remove the cover 400 and remove the grounding piece 10 from the surface of the second grounding element 30.
