Description

Technical Field

[0001] The utility model relates to the technical field of electrical connection, in particular to a low-voltage emergency quick connector which is convenient for assembly and disassembly. Background Art

[0002] Low voltage emergency connectors generally refer to connectors used to connect low voltage power supplies or devices in emergency situations. This type of connector is designed for low voltage applications and is often used in areas such as construction, automotive, medical, and electronic equipment to ensure that power or signals can be quickly and safely connected in an emergency.

[0003] For example, Chinese patent publication number CN213878514U discloses an emergency connector board end, including an insulating shell and an outer terminal axially inserted into the insulating shell, the outer terminal having a threaded rod axially protruding from the insulating shell and a terminal contact portion located in the insulating shell, an axial inner cavity is formed in the axial direction of the terminal contact portion, an inner terminal elastically connected to the outer terminal in the axial direction is installed in the axial inner cavity, an insertion space is formed between the inner terminal and the terminal contact portion, and a plurality of axially distributed annular spring contact fingers are installed on the peripheral wall of the axial inner cavity. In the present utility model, since annular spring contact fingers are installed on the peripheral wall of the axial inner cavity of the outer terminal, when the male connector is inserted into the insertion space, the male connector and the connector board end of the present utility model are more compactly matched, which has a longer service life than the leaf spring in the prior art and is not easily affected by environmental factors such as vibration.

[0004] However, the above-mentioned emergency connector uses an adjustable nut 11 and a threaded structure to lock the emergency connector in the emergency access box during installation. However, this installation and fixing method requires the staff to turn the nut multiple times during installation and disassembly, and often requires the use of corresponding tools during installation and disassembly, which makes the operation more cumbersome and inconvenient, thereby affecting the efficiency of installation and disassembly.

[0026] like Figure 1-6As shown, it is a structural schematic diagram of a low-voltage emergency quick connector that is easy to assemble and disassemble in a preferred embodiment of the utility model;

[0027] In this embodiment, it includes a connector body 1 and a mounting mechanism 2. The connector body 1 includes a socket 3, which is used to plug into an external connector joint. The front end of the socket 3 is hinged with a cover plate 4, which can be rotated to open and close, and the cover plate 4 can be opened and closed at an angle of 180 degrees. The mounting mechanism 2 includes a mounting sleeve 5 and a locking ring 6. The mounting sleeve 5 is embedded in the connector body 1 through an interference fit. One end of the mounting sleeve 5 is integrally provided with a guard plate 7. The front end of the guard plate 7 is tightly fitted with the rear end of the socket 3. The guard plate 7 can protect the socket 3 to avoid direct contact and friction between the socket 3 and the emergency access box. Positioning rods 8 are provided at the four corners of one end of the guard plate 7. The positioning rods 8 are Cylindrical structure, positioning holes 9 are provided at the four corners of the socket 3, and the positioning holes 9 are all circular holes. The number of positioning holes 9 is the same as the number of positioning rods 8. The outer diameter surface of the mounting sleeve 5 is provided with a plurality of slots 10, and the slots 10 are arranged axially along the mounting sleeve 5. One side of the plurality of slots 10 is connected with a limiting groove 11, and the limiting groove 11 is arranged vertically to the slot 10. A blind hole groove 12 is provided on the inner wall of one side of the limiting groove 11, and an elastic member 13 is embedded in the blind hole groove 12. A card bead 14 is movably provided in the blind hole groove 12, and the card bead 14 is a steel ball. A plurality of limiting blocks 15 are provided on the inner wall surface of the locking ring 6, and a card hole 16 is provided on one end surface of the plurality of limiting blocks 15, and the card hole 16 is used in conjunction with the card bead 14.

[0028] In this embodiment, the elastic member 13 abuts against the card bead 14 , and the elastic member 13 provides elastic force for the card bead 14 . When the card hole moves to the card bead 14 , the card bead 14 is pushed by the elastic force of the elastic member 13 to be inserted into the card hole 16 .

[0029] In this embodiment, the locking bead 14 is locked into the locking hole 16 , and the limiting block 15 is limited in the limiting groove 11 by the locking bead 14 being locked into the locking hole.

[0030] In this embodiment, the elastic member 13 is made of a metal spring sheet. The elastic member 13 is deformed by being squeezed. When the squeezing of the elastic member 13 is cancelled, the elastic member 13 recovers the deformation and generates elastic force.

[0031] In this embodiment, the positioning rods 8 are inserted into the positioning holes 9. The mounting sleeve 5 is conveniently mounted on the connector body 1 through a plurality of positioning holes 9 and a plurality of positioning rods 8, and plays a positioning role during installation.

[0032] Principle of the utility model:

[0033] During installation, the limiting block 15 on the locking ring 6 is inserted into the slot 10 on the installation sleeve 5. When it is inserted to the root of the slot 10, the locking ring 6 is rotated so that the limiting block 15 slides and is inserted into the limiting groove 11. The card bead 14 on the inner wall of the limiting groove 11 is inserted into the card hole 16 on the limiting block 15, and the limiting block 15 is limited in the limiting groove 11. At this time, the installation of the connector body 1 can be completed; during disassembly, the locking ring 6 is rotated in the opposite direction, and the card bead 14 is squeezed and retracted into the blind hole groove 12. The card bead 14 is disengaged from the card hole 16 to cancel the limit on the limiting block 15. The locking ring 6 is continued to be rotated so that the limiting block 15 is disengaged from the limiting groove 11. At this time, the locking ring 6 can be pulled off from the connector body 1, and the disassembly of the connector body 1 can be completed.

[0034] The utility model provides a low-voltage emergency quick connector which is easy to assemble and disassemble. Its installation method, connection method or setting method are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.
