Description

Technical Field

[0001] The present invention relates to the technical field of power connectors, and in particular to a spring-type locking power connector device. Background Art

[0002] Electrical equipment used in a home or office environment can be connected to the mains supply by a power cord that plugs into a mains wall socket at one end. Instead of permanent wiring, the other end of the power cord may be terminated with a line socket into which a matching plug may be inserted. When the plug is provided on the chassis of the device, it is referred to as a chassis plug or a panel plug. The most common example of such a power connector is a power connector that complies with the standards defined by the International Electrotechnical Commission (IEC) specification IEC 60320, particularly the C13-C14 connector used by personal computer equipment and peripherals. Some types of power connectors may also be used in the form of line plugs and panel sockets, but these types are less common. In the IEC specification, the term "connector" refers to a line socket (or panel socket), and the term "inlet" refers to a panel plug (or line plug).

[0003] The IEC standard includes two-conductor and three-conductor plugs with different current capacities and temperature ratings, which are specifically designed for the purpose of connecting the mains power cord to electrical equipment. A major advantage of the IEC connector standard is that it allows the use of interchangeable mains power cords, making it easy for equipment manufacturers to sell their equipment around the world as long as their equipment can operate under 120 / 240 volt, 50 / 60 Hz mains power.

[0004] There are still some deficiencies in the existing power connector structure. The disadvantage is that due to the unreasonable design of the existing power connector structure, the power connector and the power plug are easily pulled apart when pulled by external force, causing the power connector to easily separate from the power plug. This situation may occur when moving equipment or applying force to connecting wires, which will affect the stable transmission of power and may even cause serious problems such as power outages and equipment failures, resulting in poor practicality. Summary of the invention

[0005] In view of the deficiencies in the prior art, an object of the present invention is to provide a spring-clip locking power connector device which has a reasonable structural design, a simple structure, a reliable connection with a power plug, is convenient to use and has good practicality.

[0011] The present invention is further configured such that: the inclined portion of the locking spring is located directly below the ground wire plug through hole, and the square through hole is aligned with the ground wire plug through hole.

[0012] The present invention is further configured such that: the rear end of the power connector body is fixed to the rear cover by snap-fit ​​connection or by bolt connection or by screw connection.

[0013] The present invention is further configured as follows: a power plug is provided at the front end of the power connector body, and the power plug includes a ground wire plug. When the ground wire plug is inserted into the ground wire plug through hole, the ground wire plug head passes through the ground wire plug through hole and the square through hole in sequence and is plugged and fixed with the aligned conductive socket, and the locking spring piece is under the elastic force of the reset spring piece, so that the local position of the inner wall surface of the square through hole of the locking spring piece locks the local position of the ground wire plug; when the control button is pressed, the control button drives the locking spring piece to move downward, so that the inner wall surface of the square through hole at the locking end of the locking spring piece releases the ground wire plug; when the control button is released, the locking spring piece is automatically reset under the action of the reset spring piece.

Pressing the control button drives the locking spring plate to move downward, so that the interference between the two sides of the front square through hole and the ground wire plug is eliminated. At this time, pressing the control button can pull out the ground wire plug, that is, pull out the power plug. After pulling out the power plug, release the control button, and the locking spring plate automatically resets under the action of the reset spring plates on both sides below. The structure is simple, the connection with the power plug is reliable, the use is convenient and the practicability is good.

The inner end of the control button 4 is connected to the locking spring 3. By pressing the control button 4, the locking spring 3 is driven to deform and release the power plug.

[0021] In order to make the structural design of the present invention more reasonable, as a preferred embodiment, a rear cover 5 is provided at the lower end of the power connector body 1 in this embodiment, and a plurality of conductive plugs 6 are provided in the rear cover 5. A conductive socket 7 is fixedly provided at the inner end of each conductive plug 6, and the opening of each conductive socket 7 is aligned with a pin through hole.

[0022] Preferably, the number of the conductive plugs 6 is 3, and the inner end of each conductive plug 6 is integrally formed with the aligned conductive socket 7 or fixed by welding, and a plug through hole is provided on the back cover 5, and the lower end of each conductive plug 6 is arranged through the aligned plug through hole.

[0023] The inner end of the rear cover 5 is fixedly provided with a spring limiting protrusion 51 , and the spring limiting protrusion 51 is provided with a limiting inclined surface 511 aligned with the bending portion 311 of the locking spring 3 , and the bending portion 311 of the locking spring 3 is connected to the limiting inclined surface 511 .

The plug through hole includes a live wire plug through hole, a neutral wire plug through hole and a ground wire plug through hole 11.

[0031] like Figure 5 As shown, the ground wire pin 2 of the power plug pushes the locking spring 3 downward through the square through hole 33 of the locking spring 3, and then the front end of the locking spring 3 contacts the power connector body 1 and rotates clockwise, so that the ground wire pin 2 can pass through the square through hole 33 smoothly.

[0032] like Figure 6 As shown, after the power plug is inserted into place, the locking spring piece 3 automatically rotates and resets under the elastic force of the reset spring pieces 34 on both sides of the lower end until the local position of the inner wall surface of the square through hole 33 of the locking spring piece 3 locks the ground wire plug 2, that is, locks the power plug.

[0033] like Figure 7 As shown, by pressing the control button 4, the locking spring 3 moves downward, so that the interference between the two sides of the front square through hole 33 and the grounding plug 2 is eliminated.
