The energy storage device may be a device for storing capacitance, such as an outdoor power supply or a power supply pack. As an example, the outdoor power supply is provided with a socket 20, the power-up pack is provided with a socket 20, the outdoor power supply and the power-up pack are connected through a data line, two ends of the data line are provided with plugs 10, and the two plugs 10 of the data line are respectively plugged with the outdoor power supply and the socket 20 of the power-up pack to realize electric connection. The fool-proof design is carried out on the plug connector 10 and the plug socket 20, so that the plug connector 10 can be inserted successfully, the plug efficiency can be improved, and the use experience of customers can be improved.

The foolproof design of the receptacle 10 and the receptacle 20 will be described in detail below with reference to fig. 1-8.

The plug 10 comprises a male connector power connection conductor 11, a male connector signal conductor 12 and a male connector rubber coating piece 13, wherein the male connector power connection conductor 11 is provided with two male connector power connection conductors 11 which are positioned at the left side and the right side of the male connector signal conductor 12, and the male connector rubber coating piece 13 is injected and coated on the periphery sides of the male connector power connection conductor 11 and the male connector signal conductor 12 and is fixedly connected with the male connector power connection conductor 11 and the male connector signal conductor 12. The male head covering member 13 has an operation portion 131 to be held by a human hand and an insertion portion 132 to which the operation portion 131 is connected.

The jack 20 includes a female power conductor 21, a female signal conductor 22, and a female overmold 23. The female electrical connection conductors 21 are two and located on the left side and the right side of the female signal conductor 22, and the female rubber coating 23 is injection molded and covers the peripheral sides of the female electrical connection conductors 21 and the female signal conductor 22 to be fixedly connected with the female electrical connection conductors 21 and the female signal conductor 22. The female head rubber-covered piece 23 is provided with an insertion groove 231, the female head electric connection conductor 21 and the female head signal conductor 22 are both protruded out of the groove bottom of the insertion groove 231, the insertion groove 231 is used for insertion of the insertion part 132, when the insertion groove 231 is in insertion fit with the insertion part 132, the female head electric connection conductor 21 is in insertion connection with the male head electric connection conductor 11, and the female head signal conductor 22 is in insertion connection with the male head signal conductor 12.

In the structure shown in fig. 4 or 8, the female power conductor 21 has a cylindrical shape, and two female signal conductors 22 are provided. The female signal conductors 22 are cylindrical, and six are arranged in rows and columns. In the structure shown in fig. 3 or fig. 7, the male power connection conductor 11 is a circular tube formed by enclosing a plurality of insertion pieces, and the male power connection conductor 11 and the female power connection conductor 21 are inserted to realize power transmission. The male signal conductor 12 is in a round tube shape, and the male signal conductor 12 is inserted into the female signal conductor 22 to realize signal transmission.

It should be further noted that, in the present embodiment, for the universal interface with a tape direction, the plug 10 can only be plugged into the socket 20 in a specific direction, so as to realize signal transmission between the male signal conductor 12 and the female signal conductor 22, for example, six female signal conductors 22 shown in fig. 4 or 8 are marked one by one from 1 to 6, six male signal conductors 12 shown in fig. 3 or 7 are marked one by one from 1 to 6, and only the female signal conductors 22 and the male signal conductors 12 with the same number are plugged into each other, so as to realize signal transmission. Taking the direction as an example, if the plug 10 is turned upside down and then plugged into the socket 20, the matching of the corresponding signal conductors cannot be realized to realize signal transmission. Therefore, a reverse insertion prevention design is necessary.

Generally, the conductors are designed to be recessed to protect the conductors and to beautify the appearance. Specifically, the female electrical connection conductor 21 and the female signal conductor 22 are hidden in the insertion slot 231 on the horizontal projection. The male electrical conductor 11 and the male signal conductor 12 are enclosed by the plug portion 132. Therefore, for the insertion alignment work between the conductors, it is difficult to perform alignment by observing the positions of the conductors themselves, and it is performed by the structural features of the male and female head packings 13 and 23.

In this embodiment, the inserting portion 132 has a first region, a second region and a third region connected in sequence from left to right, the male connector signal conductor 12 is located in the second region, and the two male connector power conductors 11 are located in the first region and the third region, respectively.

The upper surface of the second area is provided with a first groove 101, and the upper surface and the lower surface of the second area are arranged in a non-vertical symmetrical mode. The upper wall of the insertion slot 231 of the insertion socket 20 is provided with a first protrusion 201, and the first protrusion 201 can be inserted into the first groove 101 and is in interference fit with the first groove 101.

Firstly, through the design of the first groove 101 and the first bump 201, the plug 10 and the socket 20 are asymmetric up and down, so that the plug 10 cannot be inserted into the socket 20 in a reverse state, and the effect of preventing reverse insertion is achieved. Secondly, since the first groove 101 is opened on the outer side surface of the socket 20 to be easily seen by human eyes, the correct plugging direction of the plug 10 is recognized through the first groove 101, which can facilitate observation and alignment. Furthermore, the first groove 101 and the first protrusion 201 are in interference fit to reduce the frictional resistance when the plug 10 and the socket 20 are plugged in the correct direction. Finally, the first groove 101 is disposed in the second area, and in combination with the illustration, in general, the diameter of the single male contact electrical conductor 11 is larger, the diameter of the male contact signal conductor 12 is smaller, the plurality of male contact signal conductors 12 are gathered in the middle of the socket 20, the socket 20 wraps the male contact electrical conductor 11 and the male contact signal conductor 12, and areas with different shapes and sizes are formed according to the male contact electrical conductor 11 and the male contact signal conductor 12, and compared with the second area, the first area and the third area have a larger structural strength requirement to resist an external force. The first groove 101 is opened in the second region, but not the first region or the third region, so that the influence on the overall strength of the insertion portion 132 can be reduced.

From the above analysis, the structural design of the plug 10 and the socket 20 provided in this embodiment can solve the problem that the existing plug 10 and the socket 20 are easily inserted reversely, and improve the convenience of operation and the insertion efficiency.

Fig. 1 and 2 show the structure of one connector, and fig. 5 and 6 show the structure of another connector. The two connectors are different in that the outer shape of the operation portion 131 of the male head packing 13 is different from that of the female head packing 14. It can be understood that the shape and size of the rubber-covered member are different, and the mating relationship between the corresponding plug 10 and the socket 20 is not affected.

In another embodiment of the present application, referring to fig. 3 or fig. 5, two first grooves 101 are disposed on the left and right sides of the male signal conductor 12. Correspondingly, referring to fig. 4 or fig. 8, there are two first bumps 201, and the two first bumps are respectively disposed corresponding to the two first grooves 101. The two first grooves 101 are respectively arranged close to the first area and the third area, the left groove wall of the first groove 101 on the left side is a boundary line of the first area and the second area, and the right groove wall of the first groove 101 on the right side is a boundary line of the second area and the third area. In combination with the above, the male signal conductors 12 are plural and concentrated at the middle position of the inserting portion 132, and the first groove 101 is disposed at the boundary of the first region, the second region and the third region, so as to reduce the influence on the conductors and make the distribution more reasonable.

In another embodiment of the present application, referring to fig. 3 or fig. 7, a second groove 102 is formed on a lower surface of the second region, and the second groove 102 and the first groove 101 are asymmetrically disposed.

Generally, when the plug 10 is held by a human hand, the plug 10 is placed with the first recess 101 facing upward or the second recess 102 facing upward. The addition of the second groove 102 enables the plug 10 to be identified in direction and aligned by the first groove 101 or the second groove 102 as a guide no matter the plug is placed in the state where the first groove 101 faces upward or the second groove 102 faces upward, thereby further facilitating the plugging operation of the plug 10 and the socket 20.

Preferably, the second protrusion 202 and the second groove 102 are interference fit to reduce resistance to the plugging engagement of the plug connector 10 with the socket 20.

Referring to fig. 3 or fig. 7, the lower surface of the plugging portion 132 is recessed upward in the second region to form a second groove 102. In other words, relative to the first area and the third area, the lower surface of the second area is raised upward by a certain height to form the second groove 102 for the second bump 202 to be inserted into, which reduces the contact area between the plug 10 and the socket 20 during plugging while saving material under the condition of ensuring the arrangement requirement of the male signal conductor 12, thereby being beneficial to reducing the difficulty of plugging.

In another embodiment of the present application, please refer to fig. 3 or fig. 7, the first region and the second region are disposed in a non-bilateral symmetry manner. Correspondingly, referring to fig. 4 or fig. 8, the left and right slot walls of the inserting slot 231 are asymmetrically arranged. This setting can realize preventing inserting the effect of turning over equally.

In this embodiment, the corner of the first area is an arc chamfer transition, and the corner of the third area is a 45 ° chamfer or a non-45 ° chamfer transition. Through the design of different chamfers, the influence on the strength of the structure is reduced while the anti-inserting effect is realized. In other embodiments, the first region and the east third region may be configured with other configurations according to practical situations, as long as non-bilateral symmetry is achieved, so that the plug connector 10 cannot be inserted into the socket 20 in a reverse direction.

In another embodiment of the present application, referring to fig. 3 or fig. 7, the first region has third grooves 103 symmetrically formed on the upper and lower side surfaces thereof.
