Technical Field

[0001] The utility model particularly relates to an electric wire plug which is convenient for replacing a power line. Background Art

[0002] The connectors of general electronic products and the plugs of electrical appliances are called plugs. Household AC power plugs and sockets have a male connector that protrudes in the shape of a rod or copper plate, which is physically inserted into a female power socket with a slot or a hole. Size is an important technical requirement that determines whether plugs, sockets and converters can be used safely and whether they meet the general interchangeability requirements to avoid misinsertion. Unqualified size will affect user use or cause hidden dangers such as poor contact and misinsertion, which may damage the equipment at the least and cause fire and electric shock accidents at the worst.

[0003] However, in actual use, most wires are connected to plugs in a fixed manner or are clamped by two outer shells of the plug. Firstly, the fixed type is not easy to disassemble. Secondly, when the outer end of the wire is clamped by the two outer shells of the plug, when the outer end of the wire is pulled by external force, the clamped part can still achieve axial movement, which is not conducive to limiting the connection between the wire and the plug. Utility Model Content

[0004] In view of the defects of the prior art, the technical problem to be solved by the utility model is to provide a wire plug which is convenient for replacing the power cord.

[0005] A wire plug for facilitating replacement of a power cord comprises a plug housing and a cable housing for connecting a power supply cable, wherein one side of the plug housing is provided with a plurality of pins that can be connected to an external socket, a connection groove is recessed at the lower end of the plug housing, a plurality of first conductive rings that are electrically connected to the pins in a one-to-one correspondence are arranged in the connection groove, the plurality of first conductive rings are arranged in sequence from the inside to the outside with the center line of the connection groove as the center, a plurality of second conductive rings are arranged at the upper end of the cable housing corresponding to the plurality of first conductive rings, the plurality of second conductive rings are electrically connected to the power supply cable respectively, the side wall of the connection groove is provided with an internal thread, the cable housing is fixedly installed in the connection groove through the internal thread, and at this time the plurality of first conductive rings are arranged in a one-to-one correspondence with the plurality of second conductive rings.

[0008] In one embodiment, the connecting member includes a limiting ring threadedly fitted on the lower end of the plug shell, and a clamping arm elastically deformable and arranged on the lower end of the plug shell. A groove is recessed along the circumference of the outer side of the cable shell, and one end of the clamping arm can be embedded in the groove. The limiting ring can move along the thread and abut against the outer side of the clamping arm to keep one end of the clamping arm in a connected state embedded in the groove.

[0009] In one embodiment, the clamp arm is initially in an elastically spaced-apart state relatively away from the connecting slot and expanding outward.

[0018] The utility model is further described below in conjunction with the accompanying drawings and specific implementation methods:

[0019] like Figures 1 to 4 As shown, the embodiment of the utility model preferably provides a wire plug that is easy to replace the power cord, including a plug housing 1 and a cable housing 2 for connecting a power supply cable, a plurality of pins 3 that can be connected to an external socket are arranged on one side of the plug housing 1, a connecting groove 4 is recessed at the lower end of the plug housing 1, a plurality of first conductive rings 5 ​​that are electrically connected to the pins 3 in a one-to-one correspondence are arranged in the connecting groove 4, and the plurality of first conductive rings 5 ​​are arranged in sequence from the inside to the outside with the center line of the connecting groove 4 as the center, a plurality of second conductive rings 6 are arranged at the upper end of the cable housing 2 corresponding to the plurality of first conductive rings 5, and the plurality of second conductive rings 6 are electrically connected to the power supply cable respectively, the side wall of the connecting groove 4 is provided with an internal thread, the cable housing 2 is fixedly installed in the connecting groove 4 through the internal thread, and at this time, the plurality of first conductive rings 5 ​​and the plurality of second conductive rings 6 are arranged in a one-to-one correspondence and in conflict with each other.

[0020] Specifically, the present application adopts a split structure to divide the plug body into a plug shell and a cable shell, and the plug shell is threadedly connected to the cable shell through a connecting groove to achieve a detachable connection between the two. When the plug shell and the cable shell are threadedly connected, a plurality of first conductive rings and a plurality of second conductive rings abut against each other to achieve conductive transmission between the two, so that the plug shell can be combined with cable shells with different current carrying capacities to facilitate replacement of the power supply cable.

[0021] Furthermore, the upper end of the cable housing 2 has a boss 21 installed and connected to the connecting groove 4, the second conductive ring 6 is arranged at the upper end of the boss 21, and an annular flange 22 is circumferentially arranged on the upper side of the cable housing 2, a first sealing groove 23 is formed between the inner side of the annular flange 22 and the boss 21, a second sealing groove 24 is formed between the outer side of the annular flange 22 and the outer edge of the cable housing 2, and sealing rings 25 are arranged in the first sealing groove 23 and the second sealing groove 24, and a groove 26 matching the annular flange 22 is recessed on the lower side of the plug housing 1, and the depth of the groove 26 is greater than the height of the annular flange 22.

[0022] Specifically, the groove of the plug housing cooperates with the annular flange of the cable housing so that when the boss is threadedly installed in the connecting groove, the annular flange and the groove are in an engaged state, and because the depth of the groove is greater than the height of the annular flange, the cable housing and the plug housing can move relative to each other along the thread and press against the sealing ring, thereby achieving a sealed and waterproof connection between the cable housing and the plug housing, and multiple waterproof protection areas are formed by dividing the annular flange, thereby greatly improving the waterproof performance.

[0023] Furthermore, the plug housing 1 is provided with a connecting member 7 capable of locking the cable housing 2 from rotating. The connecting member 7 comprises a limiting ring 71 threadedly sleeved on the lower end of the plug housing 1, and a clamping arm 72 elastically deformable and provided on the lower end of the plug housing 1. A card slot 73 is concavely formed along the circumference of the outer side of the cable housing 2, one end of the clamping arm 72 can be embedded in the card slot 73, and the limiting ring 71 can move along the thread and abut against the outer side of the clamping arm 72, so that one end of the clamping arm 72 remains in a connected state of being embedded in the card slot 73.

[0024] Specifically, after the cable housing is threadedly moved and installed in the connection groove, one end of the clamp arm of the plug housing is embedded in the slot of the cable housing to achieve relative anti-rotation between the plug housing and the cable housing, and the threads between the two are matched to achieve relative fixation between the two, effectively avoiding the problem of poor contact between the first conductive ring and the second conductive ring due to loose threads. Then, the limiting ring is moved along the threads at the lower end of the plug housing so that the inner side of the limiting ring is tightly against the outer side of the clamp arm, and then one end of the clamp arm remains in the connected state embedded in the slot, thereby achieving structural stability of the connection between the cable housing and the plug housing.

[0025] Furthermore, the clamp arm 72 is initially in an elastically spaced-away state relative to the connection slot 4. When the limit ring moves along the thread and is out of contact with the clamp arm, the clamp arm can automatically be separated from the engagement of the slot, thereby facilitating subsequent screwing of the cable housing or the plug housing to achieve disassembly between the two.

[0026] In one embodiment, the clamp arm 72 is elastically deformable and integrally connected to the plug housing 1 .

[0027] In another embodiment, the clamp arm 72 is rotatably disposed on the plug housing 1, and a torsion spring is abutted at the rotational connection between the clamp arm 72 and the plug housing 1, and the clamp arm 72 is in a relatively far-away swinging state through the torsion spring.

[0028] In summary, both embodiments can realize an elastically spaced-apart state in which the clamping arm is initially relatively spaced-apart from the connecting groove and expands outward.

[0029] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. The technicians in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and the description are only to illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
