[0019] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the implementation modes and the accompanying drawings.

[0020] like Figures 1 to 5As shown, the power strip 100 of the utility model includes a first conductive component 1, a second conductive component 2 and an insulating shell 3; the insulating shell 3 is a cubic structure. The first conductive component 1 includes a first conductive terminal 11, a second conductive terminal 12 and a third conductive terminal 13. The length extension directions of the first conductive terminal 11, the second conductive terminal 12 and the third conductive terminal 13 are perpendicular to each other and are electrically connected to each other. The second conductive component 2 includes a fourth conductive terminal 21, a fifth conductive terminal 22 and a sixth conductive terminal 23. The length extension directions of the fourth conductive terminal 21, the fifth conductive terminal 22 and the sixth conductive terminal 23 are perpendicular to each other and are electrically connected to each other. The first conductive terminal 11 and the fourth conductive terminal 21 are axially symmetrically arranged along the vertical center axis Z and extend pins 4 on the same side respectively; the pin 4 of the first conductive terminal 11 is used as a positive pin, and the pin 4 of the fourth conductive terminal 21 is used as a negative pin. The second conductive terminal 12 and the fifth conductive terminal 22 are arranged axially symmetrically along the transverse central axis X and are respectively located on opposite sides of the first conductive terminal 11 and the fourth conductive terminal 21. The third conductive terminal 13 and the sixth conductive terminal 23 are arranged axially symmetrically along the longitudinal central axis Y and are located between the first conductive terminal 11 and the fourth conductive terminal 21 and are respectively located on opposite sides of the second conductive terminal 12 and the fifth conductive terminal 22. The first conductive terminal 11 and the fourth conductive terminal 21 are respectively formed with first plug ends 11a and 21a at one end away from the plug pin 4, the second conductive terminal 12 and the fifth conductive terminal 22 are respectively formed with second plug ends 12a and 22a at at least the same end, and the third conductive terminal 13 and the sixth conductive terminal 23 are respectively formed with third plug ends 13a and 23a at at least the same end. The first plug ends 11a and 21a, the second plug ends 12a and 22a and the third plug ends 13a and 23a are respectively located on different sides of the cube of the insulating housing 3. Specifically, the pin 4 is located on a bottom surface of the cube, and the first pin 4 is located on the other top surface opposite to the bottom surface; the two second plug ends 12a, 22a are respectively located on two opposite sides of the cube; the two third plug ends 13a, 23a are located on the other two opposite sides of the cube. The insulating housing 3 is provided with two mutually insulated and isolated accommodating cavities 31, one of the two accommodating cavities 31 accommodates the first conductive terminal 11, the second conductive terminal 12 and the third conductive terminal 13; the other of the two accommodating cavities 31 accommodates the fourth conductive terminal 21, the fifth conductive terminal 22 and the sixth conductive terminal 23, and the outer side of the insulating housing 3 is provided with plug holes corresponding to the first plug ends 11a, 21a, the second plug ends 12a, 22a and the third plug ends 13a, 23a.

The connecting portions 1a of the first conductive terminal 11, the second conductive terminal 12 and the third conductive terminal 13 are connected to the matching portions 1b of the conductive terminals adjacent thereto. In this way, the three conductive terminals can be stably matched and connected without affecting the vertical arrangement between the two terminals, thereby improving the compactness of the structure and helping to reduce the volume of the power strip 100. Specifically, the connecting portion 1a extends out a card block, and the matching portion 1b is a connecting hole, and the card block is stuck in the connecting hole. In this way, the matching between the two conductive terminals can be simpler and more convenient, and the convenience of assembly is improved. Similarly, the fourth conductive terminal 21, the fifth conductive terminal 22 and the sixth conductive terminal 23 also have a connecting portion and a matching portion.

[0022] For example Figure 1 , Figure 2 and Figure 5 As shown, the insulating shell 3 is a centrally symmetrical structure around the vertical center axis Z. The two accommodating cavities 31 are each provided with a first accommodating groove 311, a second accommodating groove 312 and a third accommodating groove 313; specifically, the first accommodating groove 311 extends in the vertical direction, the second accommodating groove 312 extends in the horizontal direction, and the third accommodating groove 313 extends in the longitudinal direction. The first accommodating groove 311, the second accommodating groove 312 and the third accommodating groove 313 all pass through the insulating shell 3 to form the jack. The respective accommodating grooves of one accommodating cavity 31 respectively accommodate the respective conductive terminals of the first conductive component 1; the respective accommodating grooves of the other accommodating cavity 31 respectively accommodate the respective conductive terminals of the second conductive component 2. By providing a first receiving groove 311, a second receiving groove 312 and a third receiving groove 313 in the two receiving cavities 31, each receiving groove can accommodate a conductive terminal respectively, so that each conductive terminal can be isolated from each other, thereby preventing an arc from being generated between the two conductive terminals, effectively ensuring the safety of use and the conductive stability of the power strip 100.

[0023] For example Figure 1 , Figure 2 and Figure 5As shown, the insulating shell 3 includes a middle shell 3a and a cover 3b detachably covering the two ends of the middle shell 3a. By providing the middle shell 3a and the cover 3b connected to the two ends of the middle shell 3a, each conductive terminal can be conveniently installed in the middle shell 3a, thereby improving the convenience of assembly. Specifically, the first accommodating groove 311, the second accommodating groove 312 and the third accommodating groove 313 are all arranged in the middle shell 3a, and the first accommodating groove 311, the second accommodating groove 312 and the third accommodating groove 313 are connected to the jack on the cover 3b in a one-to-one correspondence. The first accommodating groove 311 and the second accommodating groove 312 are open structures facing the same side; the cover 3b covers the outer side of the open structure of the first accommodating groove 311 and the second accommodating groove 312 to close the outer side. A positioning hole 3c is provided in the middle shell 3a, and a positioning column 3d is provided in the cover 3b, and the positioning column 3d is inserted into the positioning hole 3c. By using the positioning column 3d to cooperate with the positioning hole 3c, the cover body 3b can be quickly assembled and connected with the middle shell 3a, thereby improving the convenience of assembly.

[0024] For example Figure 1 As shown, the insulating housing 3 is provided with a mounting foot 3e on the same side as the plug pin 4. The mounting foot 3e is an elastic hook. The mounting foot 3e can be used to quickly and conveniently position the power strip 100, thereby improving the convenience of assembly.

In addition, since six conductive terminals are used to form a plurality of plug-in terminals on different sides, the present invention can be used by a variety of electrical appliances at the same time, greatly improving the convenience of use.
