[0002] Photovoltaic brackets are used to install solar panels. In order to prevent safety accidents such as lightning strikes, the photovoltaic brackets will be grounded. The metal wires will be fixed to the photovoltaic brackets through penetrating clamps. The photovoltaic brackets will be electrically conductive with the metal wires through the penetrating clamps, and the metal wires can be grounded, thereby achieving grounding of the photovoltaic bracket.

[0003] At present, the Chinese utility model patent with announcement number CN203119117U discloses a solar photovoltaic bracket and a penetration clamp. The penetration clamp has a placement port for installing a grounding metal wire. The penetration clamp is a conductor and is provided with a notch and a first connecting piece. The notch is engaged with the edge of the photovoltaic bracket. A first through hole is provided on one side wall of the notch. The first connecting piece passes through the first through hole and presses its head end against the surface of the edge so as to pierce the insulating layer on the surface and conduct with the photovoltaic bracket.

[0004] In the prior art, similar to the above-mentioned penetration clamp, the metal wire is fixed in the placement port of the penetration clamp by tightening the metal wire with a bolt to achieve grounding. However, this fixed grounding method may cause the bolt to loosen during use, resulting in unstable contact between the bolt and the metal wire, thereby affecting the grounding effect. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of the present invention is to provide a penetration clamp with good grounding performance, which has the advantage of more firmly fixing the metal wire and making the metal wire better grounded.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0008] The base plate is connected to the side wall of the penetrating clamp body by bolts, and a first rectangular groove and a second rectangular groove are provided on the upper surface of the base plate, wherein one side wall of the first rectangular groove and the second rectangular groove is provided with an opening, a rotating shaft is installed at the notch of the first rectangular groove, a locking bar is hinged on the rotating shaft, a groove for placing the locking bar is provided on the bottom surface of the first rectangular groove, and a fixing component for fixing the locking bar is provided in the second rectangular groove.

[0009] The advantages of this solution are at least that: when fixing the metal wire, a bolt is installed in the second threaded hole, the metal wire is first fixed in the opening by the bolt, and then the locking bar is taken out of the groove, rotated in the notch of the first rectangular groove, and rotated into the second rectangular groove, and fixed in the second rectangular groove by the fixing assembly, thereby achieving a second fixation of the metal wire, and the abutment plate integrally formed on the side wall of the substrate enables the substrate to directly contact the photovoltaic bracket. The above solution solves the problem in the prior art that the metal wire and the penetrating clamp body are unstable when the bolt in the second threaded hole is loose, thereby resulting in poor grounding effect.

[0011] The advantage of this solution is at least that when the spring can make the limit pin enter the limit hole, the limit hole and the limit pin on the lock bar only need to be moved coaxially, and the limit pin can automatically enter the limit hole, making the fixing component more convenient.

[0012] The utility model is further configured as follows: an arc groove is opened on the side wall of the long side of the lock bar.

[0013] The advantage of this solution is at least that the provision of the arc-shaped groove can increase the contact area between the locking bar and the metal wire, so that the locking bar can fix the metal wire more firmly.

[0014] The utility model is further configured as follows: a silicone pad is provided on the surface of the arc-shaped groove, and an anti-slip protrusion is provided on the surface of the silicone pad.

[0015] The advantage of this solution is at least that the silicone pad can prevent the locking bar from damaging the insulation layer of the outer wall of the metal wire, thereby causing leakage.

[0016] The utility model is further configured as follows: a handle groove is provided on the side wall of the lock bar where the arc groove is provided.

[0017] The advantage of this solution is at least that the handle groove facilitates the removal of the locking bar from the groove, and can be conveniently removed from the groove when the metal wire is fixed again.

[0018] The utility model is further configured as follows: a side wall away from the limiting hole and a groove bottom of the groove are installed with magnet blocks that attract each other magnetically.

[0019] The advantage of this solution is at least that the lock bar is fixed in the groove by utilizing the attraction between opposite poles of magnets, so that the lock bar can be well stored in the groove to avoid the lock bar being broken by external force when the penetrating clip body is not in use.

[0020] The present invention is further configured as follows: a lifting plate is installed in the second rectangular groove, and a spring is provided between the lifting plate and the inner bottom surface of the second rectangular groove.

[0021] The advantage of this solution is at least that when the metal wire needs to be removed, after the fixing assembly is released from the restriction of the lock bar, the arrangement of the lifting plate and the spring facilitates the lock bar to be better ejected from the second rectangular groove.

[0022] The utility model is further configured as follows: movable grooves are symmetrically opened on the inner side wall of the first rectangular groove, and a threaded rod and a sliding rod are respectively installed in the two movable grooves, one end of the threaded rod passes through the top surface of the substrate, and a knob is installed at the end of the threaded rod that passes through, one end of the rotating shaft is threadedly connected to the threaded rod, and the other end is slidably installed on the sliding rod.

[0023] The advantage of this solution is at least that when the wire is too thin, the knob can be rotated to drive the threaded rod to rotate, thereby driving the rotating shaft to move up and down, thereby ensuring that the locking bar better fixes the metal wire.

[0024] In summary, the present invention has at least the following advantages:

[0025] 1. By setting a base plate and a fixing assembly, when fixing the metal wire, a bolt is installed in the second threaded hole, and the metal wire is first fixed in the opening by the bolt. Then the locking bar is taken out of the groove, rotated in the notch of the first rectangular groove, and rotated into the second rectangular groove, and fixed in the second rectangular groove by the fixing assembly, thereby achieving a second fixation of the metal wire. The abutment plate integrally formed on the side wall of the base plate directly contacts the photovoltaic bracket, thereby solving the problem in the prior art that the metal wire and the penetration clamp body are unstable after the bolt in the second threaded hole is loosened, resulting in poor grounding effect.

[0026] 2. By setting a spring, the spring can make the limit pin enter the limit hole. Just move the limit hole and the limit pin on the lock bar to be coaxial, and the limit pin will automatically enter the limit hole, making the fixing component more convenient. The setting of the arc groove can increase the contact area between the lock bar and the metal wire, making the lock bar more firmly fix the metal wire. The silicone pad can prevent the lock bar from damaging the insulation layer of the outer wall of the metal wire, which may cause leakage.

[0027] 3. By setting a handle groove, the handle groove has the function of facilitating the removal of the lock bar from the groove, so that it can be conveniently removed from the groove when the metal wire is fixed again; by setting a magnet block, the lock bar is fixed in the groove by utilizing the characteristic of opposite poles attracting each other, so that the lock bar can be well stored in the groove to avoid the lock bar being broken by external force when penetrating the clamp body when not in use; by setting a movable groove, a threaded rod, and a sliding rod, when the wire is too thin, by rotating the knob, the knob drives the threaded rod to rotate, thereby driving the rotating shaft to move up and down, thereby ensuring that the lock bar better fixes the metal wire.

[0035] The present invention will be described in further detail below with reference to the accompanying drawings.

[0036] A penetration clip with good grounding, such as Figure 1 As shown, it includes a penetration clamp body 1 with an opening 2 for installing a grounding metal wire, a slot 3 for fixing the penetration clamp body 1 on a photovoltaic bracket, and a first threaded hole 4 and a second threaded hole 5 that pass through the slot 3 and the opening 2 are provided on the upper surface and side wall of the penetration clamp body 1.

[0037] like Figure 1 、 Figure 2 、 Figure 3 As shown, a base plate 6 is installed on the side wall of the penetration clamp body 1, and an abutment plate 7 is integrally formed on the side wall of the base plate 6. The abutment plate 7 is located in the slot 3. The base plate 6 is connected to the side wall of the penetration clamp body 1 by bolts. A first rectangular slot 8 and a second rectangular slot 9 are provided on the upper surface of the base plate 6, wherein one side wall of the first rectangular slot 8 and the second rectangular slot 9 is provided through the opening 2, a rotating shaft 10 is installed on the slot of the first rectangular slot 8, and a locking bar 11 is hinged on the rotating shaft 10, a groove 12 for placing the locking bar 11 is provided on the bottom surface of the first rectangular slot 8, and a fixing component 13 for fixing the locking bar 11 is provided in the second rectangular slot 9.

[0038] like Figure 1-4 As shown, a sliding groove 14 is provided on the upper surface of the substrate 6, a chamber 15 is provided on the bottom surface of the sliding groove 14, a rectangular hole 16 is provided on the inner wall of the chamber 15, and the rectangular hole 16 passes through the side wall of the second rectangular groove 9. The fixing component 13 includes: a limit pin 1301 slidably installed in the chamber 15 and the sliding groove 14, and a limit hole 1302 provided on the locking bar 11, and a first spring 1303 is fixed between the limit pin 1301 and the inner wall of the chamber 15.

[0039] Furthermore, in order to facilitate the locking bar 11 to be taken out from the groove 12 more conveniently, a handle groove 19 is provided on the side wall of the locking bar 11 where the arc groove 17 is provided. By providing the handle groove 19, the user can take out the locking bar 11 from the groove 12 more conveniently.

[0040] It is worth mentioning that a magnet block 20 is installed on the side wall away from the limiting hole 1302 and the bottom of the groove 12. The magnet block 20 is installed on the side wall away from the limiting hole 1302 and the bottom of the groove 12. The locking bar 11 is fixed in the groove 12 by taking advantage of the attraction between opposite poles of magnets. The locking bar 11 can be well stored in the groove 12, and the locking bar 11 will not be broken by external forces when the penetrating clip body 1 is not in use.

[0041] To facilitate removal of the metal wire, in some embodiments, a lift plate 21 is installed within the second rectangular slot 9, with a second spring 22 disposed between the lift plate 21 and the inner bottom surface of the second rectangular slot 9 to facilitate removal of the locking bar 11 from the second rectangular slot 9. Under the action of the second spring 22 and the lift plate 21, the locking bar 11 can automatically pop out of the second rectangular slot 9 after the fixing assembly 13 is released from the locking bar 11, eliminating the need for manual removal, making operation much simpler.

[0042] like Figure 4 As shown, to increase the contact area between the locking bar 11 and the metal wire, in some embodiments, an arcuate groove 17 is formed on the long sidewall of the locking bar 11. A silicone pad 18 is provided on the surface of the arcuate groove 17, and anti-slip protrusions 1801 are provided on the surface of the silicone pad 18. The silicone pad 18 prevents the locking bar 11 from damaging the insulation layer on the outer wall of the metal wire, which could cause leakage.

[0043] like Figure 5 、 Figure 6 As shown, when the metal wire is too thin, in order to ensure that the locking bar 11 better fixes the metal wire, in some preferred embodiments, movable grooves 23 are symmetrically opened on the inner side wall of the first rectangular groove 8, and a threaded rod 24 and a sliding rod 25 are respectively installed in the two movable grooves 23. One end of the threaded rod 24 passes through the top surface of the base plate 6, and a knob 26 is installed at the end of the threaded rod 24 that passes through. One end of the rotating shaft 10 is threadedly connected to the threaded rod 24, and the other end is slidably installed on the sliding rod 25.

[0044] The working process and beneficial effects of the utility model are as follows:

[0045] When fixing the metal wire, a bolt is installed in the second threaded hole 5, and the metal wire is first fixed in the opening 2 by the bolt, and then the locking bar 11 is taken out of the groove 12, and the notch 3 of the first rectangular groove 8 is rotated and rotated into the second rectangular groove 9. When the limiting hole 1302 on the locking bar 11 and the limiting pin 1301 move to be coaxial, the limiting pin 1301 can automatically enter the limiting hole 1302 under the action of the first spring 1303, thereby fixing the locking bar 11 in the second rectangular groove 9, thereby realizing the second fixation of the metal wire, and the abutment plate 7 integrally formed on the side wall of the substrate 6 directly contacts the photovoltaic bracket, which solves the problem in the prior art that the metal wire and the penetration clamp body 1 are unstable after the bolt in the second threaded hole 5 is loosened, thereby resulting in poor grounding effect.

[0046] When the metal wire is too thin, by rotating the knob 26, the knob 26 drives the threaded rod 24 to rotate, so that the rotating shaft 10 moves up and down in the moving groove 23, ensuring that the locking bar 11 can firmly fix the metal wire.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present invention should be included in the scope of protection of the present invention.
