For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0019] Please refer to Figures 1 - 3 , an embodiment provided by the present utility model: a quick plugging and locking tool for an MC4 connector, including a first pliers rod 1 and a second pliers rod 2. The first pliers rod 1 and the second pliers rod 2 together form the plugging and locking tool of the present utility model, that is, the pliers-type tool structure as shown in the Figure 1 accompanying drawings of the specification;

[0020] Moreover, in order to improve the structural strength and insulation of the present utility model, avoid the risk of electric shock, and reduce potential safety hazards, both the first pliers rod 1 and the second pliers rod 2 are made of alumina ceramic material. When the alumina ceramic material is used in the present utility model, it has good structural strength and insulation, improving the overall use effect of the present utility model;

[0021] The first pliers rod 1 and the second pliers rod 2 have the same structure. A holding part 101 is provided at the tail end of the first pliers rod 1. A cross-connecting part 102 is fixedly connected to the top end of the holding part 101. An activity slot 103 is opened on the side wall of the cross-connecting part 102. The cross-connecting part 102 of the second pliers rod 2 is inserted into the activity slot 103 of the first pliers rod 1. The cross-connecting parts 102 between the first pliers rod 1 and the second pliers rod 2 are cross-connected and rotated through a connecting rotating shaft 3, so as to ensure the normal cross-rotating connection effect and facilitate gripping and using through the holding part 101;

[0022] Arc portions 104 are fixedly installed at the tops of the first hand pliers rod 1 and the second hand pliers rod 2. Flat head screws 105 are fixedly installed on the outer walls of the tails of the first hand pliers rod 1 and the second hand pliers rod 2. During actual use, the flat head screws 105 can be inserted into the MC4 connector, and by rotating the flat head screws 105, the locking terminals of the MC4 connector can be released from the locked state, facilitating the operation and maintenance disassembly of the MC4 connector;

[0023] Furthermore, the arc portion 104 is designed with a semi-circular structure, and the circular radius of the arc portion 104 is the same as the outer dimension radius of the MC4 connector;

[0024] According to the above structure description, when the MC4 connector operation and maintenance disassembly tool of the present utility model releases the locked state of the locking terminal through the flat head screw 105, at this time, the two arc portions 104 of the hand pliers tool of the present utility model can be placed outside the locking head of the MC4 connector. At this time, manually hold the first hand pliers rod 1 and the second hand pliers rod 2 tightly. When the first hand pliers rod 1 and the second hand pliers rod 2 are held tightly, the two groups of arc portions 104 at the front ends bite and close. After biting and closing, the two groups of arc portions 104 just tightly hold the locking head part of the M4 connector, so that the locking head can be quickly pulled out, and at the same time, after being tightly held by the ring, the locking nut at the rear end can also be quickly tightened to complete the insertion installation work.

[0025] In this embodiment, it is convenient to produce the tool through a mold. The hand-held part 101, the cross-connection part 102, and the arc portion 104 are all designed with an integrally formed structure.

[0026] Working principle: When it is necessary to perform operation and maintenance disassembly on the MC4 connector, the flat head screw 105 provided can be inserted into the locking terminal of the MC4 connector, and by rotating the flat head screw 105, the locking terminal of the MC4 connector can be released from the locked state, so as to facilitate the subsequent operation and maintenance disassembly of the MC4 connector;

[0027] After the locked state of the locking terminal, at this time, the two arc portions 104 of the hand pliers tool of the present utility model can be placed outside the locking head of the MC4 connector, that is, the locking head of the MC4 connector is placed between the two arc portions 104. At this time, manually hold the first hand pliers rod 1 and the second hand pliers rod 2 tightly. When the first hand pliers rod 1 and the second hand pliers rod 2 are held tightly, the two groups of arc portions 104 at the front ends bite and close. After the arc portion 104 bites and closes, the two groups of arc portions 104 just tightly hold the locking head part of the M4 connector, so that the locking head can be quickly pulled out by the way of ring locking, and at the same time, after being tightly held by the ring, the locking nut at the rear end can also be quickly tightened to complete the installation and locking work after insertion;

[0028] Moreover, to improve the structural strength and insulation of the present utility model, avoid the risk of electric shock, and reduce potential safety hazards, both the first pliers rod 1 and the second pliers rod 2 are made of alumina ceramic material. When the alumina ceramic material is applied to the present utility model, it has good structural strength and insulation, improving the overall use effect of the present utility model.

[0029] In summary, the MC4 connector quick plugging and locking tool of the present utility model has both a flat head screw and an encircling locking arc plugging and unplugging component. During actual use, the operation and maintenance management of the MC4 connector can be completed with a single tool, eliminating the need to equip multiple sets of tools during operation and maintenance. It is convenient to use, has a good function integration effect, and has the characteristics of quick plugging and locking. In addition, the operation and maintenance tool of the present utility model adopts a pliers-type structural design, which is convenient to use. At the same time, the overall structure is simple, the manufacturing cost is low, it has good structural strength and insulation, can effectively avoid the risk of electric shock, improve the use safety, and is conducive to popularization and use.

[0030] For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above-described exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any perspective, the embodiments should be regarded as exemplary and non-limiting. The scope of the present utility model is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present utility model. Any reference signs in the claims should not be construed as limiting the corresponding claims.
