Description

Technical Field

[0001] The present invention relates to the technical field of power strips, and in particular to a power strip with multiple holes for arbitrary insertion. Background Art

[0002] A socket strip is a multi-socket with wires, commonly known as a power strip, a strip, or a wire extension assembly. A socket strip refers to a removable multi-socket with power cords and plugs. It can connect more than one power plug, saving both space and wiring.

[0003] At present, the number of pins of the power plugs of many electrical devices is two. However, the socket combination on the power strip is now two sockets per combination, and the spacing between each combination of sockets is different from the spacing between the two sockets in the combination, and is generally relatively wider to avoid mis-insertion. This layout method occupies a large area, resulting in a reduction in the number of combination sockets; in order to increase the number of combination sockets, it also leads to the difference between the spacing between each combination socket and the spacing between the two sockets in the combination is not clear. When using, it is also necessary to clearly distinguish and align the combination sockets, and sometimes it is not easy to insert, especially for the elderly with poor eyesight. Summary of the invention

[0004] In view of the above-mentioned deficiencies, the object of the present invention is to provide a multi-hole arbitrary socket strip with reasonable structural design and convenient use.

[0005] In order to achieve the above-mentioned purpose, the present invention provides the following technical solutions:

[0006] A multi-hole random power strip, comprising a shell and a live wire contact sheet and a neutral wire contact sheet arranged in the shell, the shell is provided with a plurality of sockets arranged in sequence along a straight line, the spacing distance between any two adjacent sockets in the same straight line direction is equal, a plurality of the live wire contact sheets and a plurality of neutral wire contact sheets are arranged in sequence along the straight line direction in an alternating manner, and the positions of the sockets corresponding to them are relatively positive, so that a plug inserted into any two adjacent sockets can contact the live wire contact sheet and the neutral wire contact sheet.

[0007] As a preferred solution of the present invention, the shell includes an upper cover, a lower cover and an inner frame. The upper cover is buckled on the lower cover to form an inner cavity. The inner frame is arranged in the inner cavity. The structure is simple and easy to assemble.

[0008] As a preferred solution of the present invention, the inner frame is staggered with live wire cavities for positioning and installing the live wire contact pieces and neutral wire cavities for positioning and installing the neutral wire contact pieces, and the upper surface of the inner frame is provided with through holes connected to the live wire cavities or the neutral wire cavities, and the through holes are aligned with the jacks one by one. By staggering the live wire cavities and the neutral wire cavities in the inner frame, the live wire contact pieces and the neutral wire contact pieces can be accurately positioned and installed, ensuring that their relative positions to the jacks are correct, further improving the safety and convenience of use.

[0009] As a preferred solution of the present invention, a plurality of live wire contact pieces are connected to the same live wire metal strip; a plurality of neutral wire contact pieces are connected to the same neutral wire metal strip, a live wire clamping groove for positioning and fixing the live wire metal strip is provided on one side of the inner frame, and a neutral wire clamping groove for positioning and fixing the neutral wire metal strip is provided on the other side of the inner frame. The live wire metal strip and the neutral wire clamping groove can be stably fixed to ensure the stability of the contact piece.

[0010] As a preferred solution of the present invention, the live wire contact piece and the live wire metal strip are an integrated connection structure; the neutral wire contact piece and the neutral wire metal strip are an integrated connection structure, which is firmly connected and reduces the risk of failure caused by poor connection.

[0011] As a preferred solution of the present invention, the bottom surface of the inner frame is provided with a positioning hole, and the lower cover is provided with a positioning column adapted to the positioning hole to ensure accurate installation of the inner frame on the lower cover. The lower cover is provided with a hook foot, and the upper cover is provided with a hook groove adapted to the hook foot, which is easy to assemble and stable to assemble.

[0012] As a preferred embodiment of the present invention, it also includes a spring and a safety door. The upper surface of the inner frame is provided with a slide groove for the safety door to slide. A retaining frame is provided in the slide groove. One end of the spring presses on the retaining frame, and the other end presses on the safety door, and can push the safety door to move and close the through hole. The safety door is provided with an inclined surface toward the position of the socket. The combined design of the spring and the safety door can automatically close the socket to prevent dust and foreign matter from entering, thereby improving the safety and service life of the power strip.

[0027] Example: See Figures 1 to 9 An embodiment of the present invention provides a multi-hole arbitrary power strip, which includes a shell 1 and a live wire contact piece 2 and a neutral wire contact piece 3 arranged in the shell 1.

[0028] The housing 1 is provided with sixteen jacks 111 arranged in sequence along a straight line, and the spacing distance d between any two adjacent jacks 111 in the same straight line direction is equal. The eight live wire contact pieces 2 and the eight neutral wire contact pieces 3 are arranged in sequence along a straight line, and the positions of the jacks 111 corresponding to them are relatively positive, so that the plug can contact the live wire contact piece 2 and the neutral wire contact piece 3 when inserted into any two adjacent jacks 111. In other embodiments, the number of the jacks 111 can also be ten, twenty or more, and the number of the live wire contact pieces 2 and the neutral wire contact pieces 3 is equal, and the total number is equal to the number of the jacks 111. In addition, the jacks 111 can also be divided into two or more rows, as long as the spacing distance d between any two adjacent jacks 111 in the same straight line direction is equal.

[0029] See also 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 buckled on the lower cover 12 to form an inner cavity. To facilitate production and assembly, a hook foot 121 is provided on the lower cover 12, and a hook groove matched with the hook foot 121 is provided on the upper cover 11, which is easy to assemble and stable. The jack 111 is located on the upper cover 11. The inner frame 13 is arranged in the inner cavity. To ensure the accurate installation of the inner frame 13 on the lower cover 12, a positioning hole 133 is provided on the bottom surface of the inner frame 13, and a positioning column 122 matched with the positioning hole 133 is provided on the lower cover 12.

[0030] The live wire cavity 134 for positioning and installing the live wire contact piece 2 and the neutral wire cavity 135 for positioning and installing the neutral wire contact piece 3 are arranged alternately in the inner frame 13. The upper surface of the inner frame 13 is provided with a through hole 130 connected to the live wire cavity 134 or the neutral wire cavity 135. The through holes 130 are aligned one by one with the jacks 111. By staggering the live wire cavity 134 and the neutral wire cavity 135 in the inner frame 13, the live wire contact piece 2 and the neutral wire contact piece 3 can be accurately positioned and installed, ensuring that their relative positions with the jack 111 are correct, further improving the safety and convenience of use.

[0031] The live wire contact piece 2 is positioned and installed in the live wire cavity 134, and the neutral wire contact piece 3 is positioned and installed in 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 an integrated connection structure; the neutral wire contact piece 3 and the neutral wire metal strip are an integrated connection structure, which is firmly connected and reduces the risk of failure caused by poor connection. Preferably, a live wire clamping groove 136 for positioning and fixing the live wire metal strip is provided on one side of the inner frame 13, and a neutral wire clamping groove 137 for positioning and fixing the neutral wire metal strip is provided on the other side of the inner frame 13. The live wire metal strip and the neutral wire clamping groove 137 can be stably fixed by the live wire clamping groove 136 and the neutral wire clamping groove 137 to ensure the stability of the contact piece.

[0032] In order to improve the safety and service life of the power strip, the multi-hole arbitrary plug power strip of the present invention also includes a spring 4 and a safety door 5. The upper surface of the inner frame 13 is provided with a slide groove 131 for the safety door 5 to slide. A retaining frame 132 is provided in the slide groove 131. One end of the spring 4 presses on the retaining frame 132, and the other end presses on the safety door 5, and can push the safety door 5 to move and close the through hole 130, and also correspondingly close the socket 111. Preferably, a claw that can clamp and fix one end of the spring 4 is provided on the retaining frame 132. It ensures that the spring 4 will not loosen or fall off during long-term use, thereby 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 matter from entering.

[0033] The safety door 5 is provided with an inclined surface at the position facing the socket 111. The inclined surface design on the safety door 5 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, and the square frame has long side rods 51 and short side rods 52 arranged opposite to each other, and has good structural stability, so that the safety door 5 is more stable when moving. The inclined surface is located on the short side rods 52, and the distance D between two short side rods 52 is equal to the spacing distance d between two adjacent sockets 111. The sockets 111 are closed by the short side rods 52, 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 provided at the middle position of the bottom surface of the long side rod 51, and a support point 54 is provided on the bottom surface of one end of the long side rod 51 facing the direction of movement and opening of the safety door 5, and the bottom surface of the other end is a suspended plane; the shape of the sliding fulcrum 53 is an arc-shaped protrusion, which is more conducive to smooth sliding. The support point 54 is spherical and has a good support effect. The slope b of the inclined surface on the short side rod 52 near the support point 54 is smaller, and the slope a of the inclined surface on the short side rod 52 near the suspended plane is larger. When the plug is inserted, it will first contact the inclined surface with a larger slope, so that the end of the safety door 5 with the support point 54 is slightly tilted, and only the sliding support point 53 contacts the inner frame 13 to slide, which has less friction and is more conducive to smoothly opening the safety door 5.

[0034] When in use, since the interval d between any two adjacent sockets 111 in the same straight line direction is equal and the live wire contact piece 2 and the neutral wire contact piece 3 are arranged alternately in the straight line direction, the plug can be inserted into any two adjacent sockets to draw power without distinguishing and aligning a specific socket combination, the operation is simple, and the insertion position of the plug can be adjusted arbitrarily, which brings convenience to use and meets different usage requirements.

[0035] When not in use, the safety door 5 can automatically close the socket under the elastic force of the spring 4 to prevent dust and foreign matter from entering, effectively eliminating safety hazards, protecting the safety of children and adults in using electricity, and improving user experience.
