[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0029] The embodiments of this utility model will be described below based on its overall structure.

[0030] An electrical connector, such as Figures 1-4 As shown, it includes a set of connectors 1, with several movable blocks 2 movably connected in the middle of the set of connectors 1. The number of movable blocks 2 can be adjusted according to actual needs. Several slots 8 are provided at the bottom of each movable block 2, and pins 9 that fit into the slots 8 are provided in the slots 8. Therefore, the pins 9 can be inserted into the socket of an external socket to achieve electrical connection.

[0031] Subsequently, a groove 3 is provided on one side of each movable block 2, and a slider 4 that fits into the groove 3 is fixedly connected to the other side of the movable block 2. The slider 4 is designed with a "T" shape, so that the slider 4 on the surface of one movable block 2 can slide into the groove 3 on the surface of another movable block 2. Thus, the connection between multiple movable blocks 2 is achieved through this connection method. One connecting member 1 is provided with a groove 3 on the side near the movable block 2, and another connecting member 1 is provided with a slider 4 on the side near the movable block 2. Then, the slider 4 on the surface of one movable block 2 is slid into the groove 3 on the surface of one connecting member 1, and the slider 4 on the surface of the other connecting member 1... The slider 4 slides into the groove 3 on the surface of one of the corresponding movable blocks 2, thus connecting the movable block 2 with the connector 1, preventing the connector 1 and the movable block 2 from moving left and right independently. At the same time, each connector 1 and movable block 2 has a matching slot 5 on its surface, and a matching block 6 is slidably connected in the slot 5. The block 6 of appropriate length needs to be selected according to the actual assembled movable block 2, and then the block 6 is passed through the slot 5 on the surface of the connector 1 and the movable block 2 in sequence, thereby further increasing the connection between the connector 1 and the movable block 2, so that the connector 1 and the movable block 2 cannot move upward independently.

[0032] The bolt 7 is screwed to one side of the connecting piece 1 and contacts the surface of the clamping block 6, so that the bolt 7 is screwed to press the clamping block 6, thereby fixing the position of the clamping block 6, increasing the connection between the connecting piece 1 and the movable block 2, avoiding loosening under external force and affecting use, and the rubber layer is arranged on one side of each bolt 7 close to the clamping groove 5, thereby increasing the friction between the bolt 7 and the clamping block 6, and better fixing the position of the clamping block 6.

[0033] Therefore, when the electrical connector is used, the connection between the connecting piece 1 and the movable block 2 is increased by the sliding groove 3, the sliding block 4, the clamping groove 5 and the clamping block 6, so that they are assembled into an electrical connector, and the pin 9 is matched with the jack of the external socket, thereby better realizing electrical connection, increasing the flexibility and expandability of the electrical connector, and when one pin 9 is damaged, only the movable block 2 with the damaged pin 9 needs to be replaced, without replacing the entire electrical connector, thereby reducing the use cost.

[0034] Meanwhile, a group of iron sheets 11 are arranged on both sides of each movable block 2, so that when the iron sheets 11 of adjacent groups of movable blocks 2 contact each other, the connected movable blocks 2 are mutually electrified, so that only one movable block 2 connected to an external power supply can electrify multiple movable blocks 2, thereby using the entire electrical connector, thereby increasing the convenience of use, and when the iron sheet 11 on the surface of the movable block 2 contacts the connecting piece 1, the connecting piece 1 is not designed as a conductive part, so that the connecting piece 1 is not electrified, thereby not affecting the normal use of the electrical connector.

[0035] Further, a plurality of heat dissipation fins 10 are fixedly connected to the surface of each movable block 2, so that when the electrical connector is used, the heat dissipation fins 10 increase the area of the movable block 2 in contact with the air, thereby increasing the heat dissipation efficiency, improving the stability and service life of work, and a label groove 12 is fixedly connected to one side of each movable block 2, so that the label of each movable block 2 is placed in the label groove 12 on the surface thereof, thereby facilitating management and use in the later period, and a rubber pad 13 is arranged on the bottom of each movable block 2, so that when the pin 9 at the bottom of the movable block 2 is inserted into the jack of the external socket, the movable block 2 contacts the surface of the external socket, thereby increasing the sealing property of the two by the rubber pad 13, avoiding external dust, moisture and the like from entering the connection, thereby affecting the electrical connection.

[0036] Although the embodiments of the utility model have been shown and described, the specific embodiments are only the explanation of the utility model, and are not the limitation of the utility model, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable way, the person skilled in the art can make the modification, replacement and change of no creative contribution to the embodiment according to the need after reading the specification without departing from the principle and the purpose of the utility model, but as long as in the patent right claim range of the utility model, it is protected by the patent law.
