Description

Technical Field

[0001] This utility model relates to the field of DC power sockets, specifically DC power sockets. Background Technology

[0002] DC power sockets, as a standard power interface, are widely used in various electronic devices.

[0003] The existing DC socket contains three sets of terminals: conductive post terminals, spring contact terminals, and socket terminals. The conductive posts and spring contact terminals are all located inside the socket and are isolated only by an air gap. When the device is subjected to accidental drop, severe vibration, or external mechanical impact, the internal components may be displaced, causing the conductive posts and spring contact to make contact and resulting in a short circuit. This may trigger overcurrent protection and damage the device. Therefore, a DC power socket is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a DC power socket to solve the problems mentioned in the background art.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A DC power socket includes a housing. One end of the housing has a socket, and the other end has a connection port communicating with the socket. A conductive post is installed on the connection port. A slot is opened on the inner wall of the housing, and a spring is installed in the slot. A shunt terminal is installed on one side of the housing, and the spring contacts and shunt terminals. An insulating partition is slidably installed inside the housing. A reset component is provided between the insulating partition and the inner wall of the housing. The insulating partition is located between the conductive post and the spring.

[0007] Preferably, one end of the shunt terminal is located inside the slot, and the other end is located outside the housing. One end of the spring contact abuts against the shunt terminal, and the other end penetrates through the housing. A contact is provided in the middle of the spring contact, and the contact is located on one side of the conductive post.

[0008] Preferably, one end of the conductive post is fixedly connected to a connecting post, the connecting post is installed inside the connection port, and one end of the connecting post penetrates the outer shell and is snapped onto a center pin terminal.

[0009] Preferably, a cap is fixed to the end of the connecting post away from the conductive post, the cap is pressed against the center pin terminal, and a baffle is fixed to one end of the outer shell, with the center pin terminal passing through the baffle.

[0010] Preferably, one end of the outer shell is provided with a sliding groove, one end of the insulating partition slides in the sliding groove, the sliding groove passes through the central pin terminal, and both sides of the outer shell are provided with sliding grooves, and both sides of the insulating partition are fixedly connected with connecting plates, and the two sets of connecting plates are respectively slidably installed in the two sets of sliding grooves.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] DC power outlet, such as Figures 1-4 As shown, the device includes a housing 1. One end of the housing 1 has a socket 2, and the other end has a connection port 3 that communicates with the socket 2. A plug is inserted into the socket 2. A conductive post 5 is installed on the connection port 3, and the plug is inserted into the conductive post 5. A slot 4 is opened on the inner wall of the housing 1, and a spring piece 11 is installed in the slot 4. A shunt terminal 13 is installed on one side of the housing 1, and the spring piece 11 contacts and engages with the shunt terminal 13. An insulating partition 14 is slidably installed inside the housing 1. A reset component is provided between the insulating partition 14 and the inner wall of the housing 1. The insulating partition 14 is located between the conductive post 5 and the spring piece 11.

[0023] When the plug is not inserted into the socket, one end of the spring contact 11 contacts the shunt terminal 13. The reset assembly presses the insulating partition 14 to separate the conductive post 5 and the spring contact 11. When the plug is inserted into the socket, the plug presses the insulating partition 14 and the spring contact 11, pushing the insulating partition 14 to slide. The reset assembly retracts, and the plug indirectly contacts the conductive post 5 and the spring contact 11. At the same time, the spring contact 11 separates from the shunt terminal 13. The resistance of the reset assembly to the plug is less than the squeezing friction of the spring contact 11 to the plug. When the plug is pulled out of the socket, the reset assembly returns to its original shape, presses the insulating partition 14, and pushes the insulating partition 14 between the conductive post 5 and the spring contact 11, separating the conductive post 5 and the spring contact 11.

[0024] When the plug is not inserted into the socket, one end of the spring contact 11 contacts the shunt terminal 13, and the other end passes through the outer shell 1 to form a terminal. When the plug is inserted into the socket, the plug and the contact point 12 of the spring contact 11 are pressed into contact to form a connection.

[0025] Both conductive post 5 and connecting post 6 are conductive. The center pin terminal 8 is used for current conduction, and the connecting post 6 is conductively connected to the center pin terminal 8.

[0026] Two sets of contacts 12 are provided on the spring 11. The height of the set of contacts 12 closer to the shunt terminal 13 is greater than the height of the other set of contacts 12. When the plug (cylindrical, for example, a cylinder with a hole in the center, into which the conductive post enters) is inserted, the contact 12 with the higher height has the largest displacement, which makes the separation distance between the spring 11 and the shunt terminal 13 larger.

[0027] A larger diameter end cap 7 is fixed to the end of the connecting post 6 away from the conductive post 5. The end cap 7 is pressed against the center pin terminal 8. A baffle 9 is fixed to one end of the outer shell 1. The center pin terminal 8 passes through the baffle 9. The baffle 9 limits the center pin terminal 8 in the middle to prevent it from shifting.

[0028] Slide 10 provides space for the sliding of insulating partition 14, slide 2 16 provides space for the sliding of connecting plate 15, connecting plate 15 drives insulating partition 14 to slide, reset assembly is installed in slide 2 16, rod 17 is plugged in, since the outer shell 1 is assembled from two structures, rod 17 is easy to disassemble, rod 17 limits the sliding path of connecting plate 15, spring 18 is always in a compressed state, squeezing connecting plate 15 and pushing insulating partition 14, so that insulating partition 14 is held between conductive post 5 and spring 11.

[0029] The working principle of the DC power socket provided by this utility model is as follows:

[0030] When the plug is not inserted into the socket, under the pushing force of the spring 18, a physical insulation barrier is formed between the conductive post 5 of the insulating partition 14 and the spring contact 11. When the equipment is subjected to severe vibration or impact, the insulating partition 14 still separates the conductive post 5 and the spring contact 11 to prevent short circuit inside the socket. When the plug is inserted, the tip of the plug first pushes the insulating partition 14 to overcome the elastic force of the spring 18, causing the insulating partition 14 to retract. The center hole of the plug is inserted into the conductive post 5, and its outside contacts the contact point 12 of the spring contact 11, forming a normal power supply circuit, and the equipment is powered on and working. When the plug is pulled out, the pushing force on the insulating partition 14 disappears, and the elastic force of the spring 18 pushes the insulating partition 14 forward to reset. The partition once again isolates the conductive post 5 and the spring contact 11 to avoid accidental contact that could cause a short circuit.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
