Description

Technical Field

[0001] This utility model relates to the field of power strip technology, and in particular to a multi-hole arbitrary power strip. Background Technology

[0002] A power strip, also known as a power outlet or extension cord, is a multi-outlet socket with a built-in cord. It can connect more than one power outlet, saving both space and wiring.

[0003] Currently, many electrical appliances have two-pronged plugs. However, power strips now often have two-pronged sockets per combination, and the spacing between the two sockets in each combination differs from the spacing between the two individual sockets in the combination—generally being wider to prevent mis-insertion. This layout takes up more space, reducing the number of sockets in a combination. To increase the number of sockets in a combination, the difference between the spacing between the two sockets in a combination and the spacing between the two individual sockets in the combination becomes less clear. Users must carefully distinguish and align the sockets, sometimes making insertion difficult, especially for elderly people with poor eyesight. Utility Model Content

[0004] In view of the above-mentioned shortcomings, the purpose of this utility model is to provide a multi-hole arbitrary power strip with a reasonable structural design and convenient use.

[0005] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0006] A multi-hole power strip includes a housing and live wire contact pieces and neutral wire contact pieces disposed within the housing. The housing has a plurality of sockets arranged at intervals along a straight line, with equal spacing between any two adjacent sockets in the same straight line. The plurality of live wire contact pieces and the plurality of neutral wire contact pieces are arranged alternately along a straight line and are respectively aligned with the positions of their corresponding sockets, so that when a plug is inserted into any two adjacent sockets, it can make contact with the live wire contact piece and the neutral wire contact piece.

[0007] As a preferred embodiment of this utility model, the housing includes an upper cover, a lower cover, and an inner frame. The upper cover is fastened to the lower cover and forms an inner cavity, and the inner frame is disposed in the inner cavity. The structure is simple and easy to assemble.

[0008] In a preferred embodiment of this invention, the inner frame is provided with staggered live wire cavities for positioning and installing the live wire contact piece and neutral wire cavities for positioning and installing the neutral wire contact piece. The upper surface of the inner frame has through holes communicating with either the live wire or neutral wire cavity, and these through holes are aligned with the sockets. By staggering the live wire and neutral wire cavities within the inner frame, the live wire and neutral wire contact pieces can be precisely positioned and installed, ensuring their correct relative positions with the sockets, further improving safety and convenience of use.

[0009] In a preferred embodiment of this invention, several live wire contact pieces are connected to the same live wire metal strip; several neutral wire contact pieces are connected to the same neutral wire metal strip. One side of the inner frame is provided with a live wire clamping groove for positioning and fixing the live wire metal strip, and the other side of the inner frame is provided with a neutral wire clamping groove for positioning and fixing the neutral wire metal strip. The live wire clamping groove and the neutral wire clamping groove can stably fix the live wire metal strip, ensuring the stability of the contact pieces.

[0010] As a preferred embodiment of this utility model, the live wire contact piece and the live wire metal strip are integrally connected; the neutral wire contact piece and the neutral wire metal strip are integrally connected, which ensures a firm connection and reduces the risk of failure due to poor connection.

[0011] In a preferred embodiment of this utility model, the bottom surface of the inner frame is provided with positioning holes, and the lower cover is provided with positioning posts that match the positioning holes, ensuring accurate installation of the inner frame on the lower cover. The lower cover is provided with hook feet, and the upper cover is provided with hook grooves that match the hook feet, making assembly easy and ensuring stable assembly.

[0012] In a preferred embodiment of this invention, it further includes a spring and a safety door. The upper surface of the inner frame is provided with a groove for the safety door to slide. A stop is provided within the groove. One end of the spring presses against the stop, and the other end presses against the safety door, thus pushing the safety door to move and close the through hole. The safety door has an inclined surface facing the socket. The combined design of the spring and safety door can automatically close the socket, preventing dust and foreign objects from entering, thus improving the safety and service life of the power strip. Simultaneously, the inclined surface design on the safety door allows the plug to easily push open the safety door and insert into the socket.

[0013] In a preferred embodiment of this invention, the retainer is provided with a claw that can clamp and fix one end of the spring. This ensures that the spring will not loosen or fall off during long-term use, improving the reliability and safety of the power strip.

[0014] In a preferred embodiment of this invention, the safety door is a square frame with long and short side bars arranged in pairs opposite each other, providing good structural stability and making the safety door more stable during movement. The inclined surface is located on the short side bars, and the distance between the two opposite short side bars is equal to the spacing between two adjacent sockets. The short side bars close the sockets, and when the short side bars are removed, the plug can slide into the socket along the inclined surface.

[0015] In a preferred embodiment of this invention, a sliding fulcrum is provided at the middle of the bottom surface of the long side rod, and a support point is provided at one end of the long side rod facing the direction of movement and opening of the safety door, while the bottom surface of the other end is a suspended plane. The slope of the inclined surface on the short side rod near the support point is smaller, while the slope of the inclined surface on the short side rod near the suspended plane is larger. When the plug is inserted, it first contacts the steeper inclined surface, causing the end of the safety door with the support point to slightly tilt upwards. It then slides only through the sliding fulcrum against the inner frame, resulting in less friction and smoother opening of the safety door.

[0016] The beneficial effects of this utility model are as follows: The structure of this utility model is reasonably designed. By arranging the sockets sequentially at intervals along a straight line on the housing, with the interval d between any two adjacent sockets in the same straight line being equal, and by staggering the live wire contact and neutral wire contact along a straight line, the plug can be inserted into any two adjacent sockets to draw power without needing to distinguish or align specific socket combinations, thus improving ease of use, especially for elderly users and those with poor eyesight. The plug's insertion position can also be adjusted arbitrarily to meet different usage needs. Furthermore, a safety door is added; when not in use, the safety door automatically closes the sockets to prevent dust and foreign objects from entering, improving the safety and lifespan of the power strip.

[0026] Example: See Figures 1 to 9 This utility model provides a multi-hole arbitrary power strip, which includes a housing 1 and a live wire contact piece 2 and a neutral wire contact piece 3 disposed in the housing 1.

[0027] The housing 1 has sixteen sockets 111 arranged sequentially and spaced apart along a straight line, with the spacing d between any two adjacent sockets 111 in the same straight line being equal. Eight live wire contacts 2 and eight neutral wire contacts 3 are arranged alternately along a straight line, and are respectively aligned with their corresponding sockets 111, ensuring that the plug can make contact with both the live wire contact 2 and the neutral wire contact 3 when inserted into any two adjacent sockets 111. In other embodiments, the number of sockets 111 can be ten, twenty, or more, while the number of live wire contacts 2 and neutral wire contacts 3 is equal, and their combined number is equal to the number of sockets 111. Furthermore, the sockets 111 can be arranged in two or more rows, as long as the spacing d between any two adjacent sockets 111 in the same straight line is equal.

[0028] See Figure 2 and Figure 3 The housing 1 includes an upper cover 11, a lower cover 12, and an inner frame 13. The upper cover 11 is fastened to the lower cover 12 to form an inner cavity. For ease of production and assembly, the lower cover 12 is provided with hook feet 121, and the upper cover 11 is provided with hook grooves that are compatible with the hook feet 121, making assembly easy and stable. The insertion hole 111 is located on the upper cover 11. The inner frame 13 is disposed in the inner cavity. To ensure accurate installation of the inner frame 13 on the lower cover 12, the bottom surface of the inner frame 13 is provided with positioning holes 133, and the lower cover 12 is provided with positioning posts 122 that are compatible with the positioning holes 133.

[0029] The inner frame 13 has staggered arrangement of a live wire cavity 134 for positioning and installing the live wire contact piece 2 and a neutral wire cavity 135 for positioning and installing the neutral wire contact piece 3. The upper surface of the inner frame 13 has through holes 130 communicating with either the live wire cavity 134 or the neutral wire cavity 135, and these through holes 130 are aligned with the sockets 111. By staggering the live wire cavity 134 and the neutral wire cavity 135 within the inner frame 13, the live wire contact piece 2 and the neutral wire contact piece 3 can be precisely positioned and installed, ensuring their correct relative positions with the sockets 111, further improving safety and convenience of use.

[0030] The live wire contact piece 2 is positioned and installed within the live wire cavity 134, and the neutral wire contact piece 3 is positioned and installed within the neutral wire cavity 135. All live wire contact pieces 2 are connected to the same live wire metal strip; all neutral wire contact pieces 3 are connected to the same neutral wire metal strip. Preferably, the live wire contact piece 2 and the live wire metal strip are integrally connected; the neutral wire contact piece 3 and the neutral wire metal strip are also integrally connected, ensuring a secure connection and reducing the risk of malfunctions due to poor connection. Preferably, one side of the inner frame 13 has a live wire clamping groove 136 for positioning and fixing the live wire metal strip, and the other side of the inner frame 13 has a neutral wire clamping groove 137 for positioning and fixing the neutral wire metal strip. The live wire clamping groove 136 and the neutral wire clamping groove 137 can stably fix the live wire metal strip, ensuring the stability of the contact pieces.

[0031] To improve the safety and service life of the power strip, this utility model of a multi-hole arbitrary power strip also includes a spring 4 and a safety door 5. The upper surface of the inner frame 13 is provided with a sliding groove 131 for the safety door 5 to slide. A stop 132 is provided in the sliding groove 131. One end of the spring 4 presses against the stop 132, and the other end presses against the safety door 5, which can push the safety door 5 to move and close the through hole 130, and correspondingly close the socket 111. Preferably, the stop 132 is provided with a claw that can clamp and fix one end of the spring 4. This ensures that the spring 4 will not loosen or fall off during long-term use, improving the reliability and safety of the power strip. The combined design of the spring 4 and the safety door 5 can automatically close the socket 111 to prevent dust and foreign objects from entering.

[0032] The safety door 5 has an inclined surface facing the socket 111. This inclined surface design allows the plug to easily push open the safety door 5 and insert into the socket 111. Specifically, the safety door 5 is a square frame with two opposing long side rods 51 and short side rods 52, providing good structural stability and making the safety door 5 more stable during movement. The inclined surface is located on the short side rods 52, and the distance D between the two opposing short side rods 52 is equal to the interval d between two adjacent sockets 111. The short side rods 52 close the socket 111, and when the short side rods 52 are removed, the plug can slide into the socket 111 along the inclined surface. A sliding fulcrum 53 is located in the middle of the bottom surface of the long side rod 51. One end of the long side rod 51 facing the direction of opening of the safety door 5 has a support point 54, while the other end is a suspended plane. The sliding fulcrum 53 has an arc-shaped protrusion, which facilitates smooth sliding. The support point 54 is spherical, providing good support. The slope b of the inclined surface on the short side rod 52 located near the support point 54 is smaller, while the slope a of the inclined surface on the short side rod 52 located near the suspended plane is larger. When the plug is inserted, it first contacts the steeper inclined surface, causing the end of the safety door 5 with the support point 54 to tilt slightly upwards. It then slides only through the sliding fulcrum 53 against the inner frame 13, resulting in less friction and smoother opening of the safety door 5.

[0033] In use, because the distance d between any two adjacent sockets 111 in the same straight direction is equal, and the live wire contact piece 2 and the neutral wire contact piece 3 are arranged alternately in a straight line, the plug can be inserted into any two adjacent sockets to draw power without distinguishing or aligning specific socket combinations. The operation is simple, and the insertion position of the plug can be adjusted arbitrarily, bringing convenience to use and meeting different usage needs.

[0034] When not in use, the safety door 5 can automatically close the socket under the elastic force of the spring 4, preventing dust and foreign objects from entering, effectively eliminating safety hazards, protecting the electrical safety of children and adults, and improving the user experience.
