Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment disassembly, and in particular is a special disassembly tool for MC4 photovoltaic connectors used in multiple scenarios. Background Art

[0002] With the widespread popularization and in-depth application of new energy technologies, the number of power generation units is increasing day by day. The efficient electrical connection between them mainly relies on the plug-in design of the MC4 connector, which greatly facilitates the installation and initial commissioning process. However, in the long-term operation and maintenance practice, especially in the face of installation adjustment, daily maintenance and troubleshooting, frequent disassembly of the male and female heads of the MC4 connector has become a challenge.

[0003] There are a wide variety of disassembly devices for MC4 connectors on the market, made of various materials, but this also leads to uneven product quality. Due to the extremely limited space between the densely distributed MC4 connectors on the inverter, some products, especially the disassembly end, are prone to performance degradation due to material fatigue during long-term use, and even become difficult to disassemble.

[0004] Therefore, a special disassembly tool for MC4 photovoltaic connectors used in multiple scenarios is needed to solve the above problems. Utility Model Content

[0005] 1. Technical issues to be resolved

[0006] The utility model provides a special disassembly tool for MC4 photovoltaic connectors used in multiple scenarios, aiming to solve the problems of the existing MC4 disassembly tools on the market mentioned in the background technology, such as easy fatigue of the material, limited applicability, and inconvenient operation.

[0007] (II) Technical solution

[0008] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a special disassembly tool for MC4 photovoltaic connector used in multiple scenarios, comprising a handpiece, a clamping piece fixedly connected to one end of the handpiece for clamping the groove position of the female head of the connector, a clamping opening opened on the end of the clamping piece away from the handpiece, and a pressing head symmetrically fixedly installed at the open end of the clamping opening for squeezing the buckle on the male head of the connector; the combined design of the handpiece, the clamping piece, the clamping opening and the pressing head enables the disassembly tool to accurately clamp the groove position of the female head of the connector and effectively squeeze the buckle on the male head of the connector, thereby realizing the rapid and non-destructive disassembly of the MC4 photovoltaic connector in different installation scenarios, improving the convenience of operation, and further reducing material fatigue and damage caused by improper operation.

[0009] In order to improve the flexibility of using the disassembly tool, the sides of the two pressing heads close to each other are both wedge-shaped structures; the pressing heads with wedge-shaped structures can adapt to the groove openings of different models or narrow connector female heads to a certain extent, thereby realizing the effective disassembly of various models of MC4 photovoltaic connectors.

[0010] In order to further improve the applicability of the disassembly tool, an insulating component is provided at one end of the handpiece away from the chuck piece; the design of the insulating component enables the disassembly tool to be safely used in a variety of complex environments such as electrified, humid, dusty, etc., thereby improving its applicability in multiple scenarios.

[0011] Preferably, in order to further reduce the fatigue of the disassembly tool material during use and to make it more durable, the angle between the handpiece and the chuck piece is 90 degrees; the 90-degree angle makes the connection between the handpiece and the chuck piece more stable, and can more effectively disperse the stress and impact force generated during the operation, which helps to reduce material fatigue and damage caused by stress concentration.

[0012] Preferably, in order to be able to apply force well and reduce the wear on the buckle, the end of the pressing head is a conical structure; the design of the conical structure allows the pressing head to have good guidance when inserted into the groove of the connector female head, and can more easily find and accurately align the buckle position, which helps the operator to apply force more accurately, ensure the smooth progress of the disassembly process, and reduce impact and damage to the buckle.

[0013] Preferably, in order to ensure the insulation performance, the insulating component includes a sleeve block mounted on the end of the handpiece away from the clamping piece and an insulating pad fixedly arranged on the end of the sleeve block away from the handpiece, and the handpiece is slidably connected in the sleeve block; the insulating component consists of a two-layer structure of the sleeve block and the insulating pad, forming double insulation protection for the handpiece, which can effectively isolate the current.

[0014] Preferably, in order to allow adjustability between the handpiece and the sleeve block, the insulating assembly also includes a locking screw that longitudinally penetrates the sleeve block at one end away from the insulating pad and is threadedly connected to the sleeve block for abutting the handpiece, and a knob fixedly installed on the top of the locking screw; by rotating the knob, the operator can easily adjust the position of the locking screw in the sleeve block, thereby changing the protruding length of the handpiece relative to the sleeve block. This adjustability enables the disassembly tool to adapt to different working environments and operating requirements, further improving the flexibility of use.

[0015] Preferably, in order to ensure the stability of the locking screw abutting the handpiece, a first bevel tooth is fixedly provided on one side of the knob close to the locking screw, and a second bevel tooth meshing with the first bevel tooth is provided at a position of the sleeve corresponding to the knob; the meshing design of the first bevel tooth and the second bevel tooth forms a mechanical locking mechanism. When the handpiece is adjusted and the locking screw is used to abut the handpiece, this locking mechanism is more stable than a simple screw connection and can prevent loosening due to vibration or external force.

[0016] (III) Beneficial effects

[0017] The disassembly tool clamps the groove of the female connector through the pressure head and squeezes the buckle on the male connector, which can realize the rapid and non-destructive disassembly of the MC4 photovoltaic connector in different installation scenarios, improve the convenience of operation, and thus reduce material fatigue and damage caused by improper operation;

[0018] By providing insulating components on the disassembly tool, it can be used safely in a variety of complex environments such as electrical, humid, dusty, etc., further improving its applicability in multiple scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, 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.

[0030] The utility model provides a special disassembly tool for MC4 photovoltaic connectors used in multiple scenarios, such as Figure 1-Figure 3 As shown, the disassembly tool includes a hand piece 3, a clamping piece 4 fixedly connected to one end of the hand piece 3 for clamping the groove 11 of the connector female head 1, a clamping opening 41 opened at the end of the clamping piece 4 away from the hand piece 3, and a pressing head 5 symmetrically fixedly installed at the open end of the clamping opening 41 for squeezing the buckle 21 on the connector male head 2; the sides of the two pressing heads 5 close to each other are both wedge-shaped structures; an insulating component 6 is provided at the end of the hand piece 3 away from the clamping piece 4.

[0031] It should be noted that the handpiece 3, the chuck piece 4 and the pressing head 5 are integrally formed and made of stainless steel; the handpiece 3, the chuck piece 4 and the pressing head 5 are processed and manufactured as a whole, which can eliminate the connection gaps and potential loose points between the components. At the same time, the stainless steel material makes the disassembly tool have excellent mechanical properties and corrosion resistance.

[0032] When in use, due to the setting of the clamp 41, the handpiece 3 can be first held by hand, and the clamp 4 can be clamped on the connector female head 1, and it is ensured that the pressure head 5 is aligned with the groove 11 of the connector female head 1. Since the two pressure heads 5 are close to each other on one side and have a wedge-shaped structure, at this time, the handpiece 3 is held by hand and the pressure head 5 is pushed downward, and the pressure head 5 can be easily inserted into the groove 11 and squeezed and inserted into the buckle 21 at the position of the groove 11. After that, by squeezing the pressure head 5 and manually pulling the connector male head 2, different connector male heads 2 and connector female heads 1 can be quickly plugged in. When the handpiece 3 is held by hand for operation, due to the presence of the insulating component 6, the disassembly tool can be safely used in various complex environments such as live, humid, and dusty environments, thereby improving its applicability in multiple scenarios.

[0033] Specifically, the insulating assembly 6 includes a sleeve block 61 sleeved on the end of the handpiece 3 away from the clamping member 4 and an insulating pad 62 fixedly arranged on the end of the sleeve block 61 away from the handpiece 3, and the handpiece 3 is slidably connected in the sleeve block 61;

[0034] When the disassembly tool is needed, the operator can hold it at the position of the insulating pad 62. The double protection of the sleeve block 61 and the insulating pad 62 can prevent the operator's hand from directly contacting the handpiece 3, thereby improving the safety of the operation.

[0035] Furthermore, the insulating assembly 6 further includes a locking screw 63 which longitudinally penetrates through one end of the sleeve 61 away from the insulating pad 62 and is threadedly connected to the sleeve 61 for abutting against the handpiece 3, and a knob 64 which is fixedly mounted on the top of the locking screw 63;

[0036] When using the disassembly tool, the operator can rotate the knob 64 to loosen the abutment of the locking screw 63 on the handpiece 3, and then make the handpiece 3 slide in the sleeve block 61 to adjust the length between the sleeve block 61 and the handpiece 3 to meet different operating requirements. After adjusting the length between the handpiece 3 and the sleeve block 61, the knob 64 can be rotated in the opposite direction to tighten the handpiece 3 with the locking screw 63, so that the handpiece 3 can be fixed in the sleeve block 61 for subsequent use.

[0037] Furthermore, a first bevel tooth 65 is fixedly provided on one side of the knob 64 close to the locking screw 63, and a second bevel tooth 66 meshing with the first bevel tooth 65 is provided at a position of the sleeve 61 corresponding to the knob 64;

[0038] When the length between the sleeve block 61 and the handpiece 3 is adjusted, the knob 64 is rotated in the opposite direction to make the locking screw 63 press against the handpiece 3, and the first bevel teeth 65 provided on the knob 64 will engage with the second bevel teeth 66 provided on the sleeve block 61. Therefore, after the position of the handpiece 3 is adjusted, the locking screw 63 can be stably connected to the sleeve block 61 under the meshing and locking action of the first bevel teeth 65 and the second bevel teeth 66, thereby preventing loosening due to vibration or external force and improving the stability of the disassembly tool when in use.

[0039] Among them, in order to further reduce the fatigue of the disassembly tool material and make it more durable, the angle between the handpiece 3 and the chuck piece 4 is 90 degrees; the 90-degree angle makes the connection between the handpiece 3 and the chuck piece 4 more stable, and can more effectively disperse the stress and impact force generated during the operation, which helps to reduce material fatigue and damage caused by stress concentration.

[0040] In addition, in order to be able to apply force well and reduce the wear on the buckle 21, the end of the pressing head 5 is a conical structure; the design of the conical structure enables the pressing head 5 to have good guidance when inserted into the groove 11 of the connector female head 1, and can more easily find and accurately align the position of the buckle 21, which helps the operator to apply force more accurately, ensure the smooth progress of the disassembly process, and reduce the impact and damage to the buckle 21.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
