Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the embodiments of the present invention are clearly and completely described with reference to the drawings in the embodiments of the present invention, and obviously, the embodiments described below are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
The technical solution of the present invention is further explained by the following embodiments with reference to the accompanying drawings.
Referring to fig. 1 to 2, the present embodiment provides a multifunctional power adapter suitable for a substation switch, including a switching boss 10 and a plurality of switches, where the exterior of the switching boss 10 is a rectangular structure; adapter boss 10 forward extension has power cord binding post 1, backward extension has article letter plug 2, left extension has article style of calligraphy public plug 3, right extension has 8 style of calligraphy public plug 4, downward extension has 8 letter plug 5. Each plug is connected with the power line wiring terminal 1 through one switch.
In this embodiment, the power line terminal 1 includes two metal wiring portions and a wiring insulating layer 101 covering the two metal wiring portions. The metal wire portion includes a metal tube 102 and a locking bolt 103. The insulating part, the adapter boss 10 and the wiring insulating layer 101 of each plug are of an integrated structure and are produced through an injection molding process.
The switching boss 10 is internally provided with a containing cavity, and the switch comprises a metal conductive part positioned in the containing cavity and a button extending to the outside of the switching boss 10. It will be appreciated that pressing different buttons causes different plugs to be electrically connected to the metal wiring portions through the metal conductive portions of the corresponding switches.
Specifically, the switches comprise a first switch 6 for connecting the power line wiring terminal 1 with the delta-shaped female plug 2, a second switch for connecting the power line wiring terminal 1 with the delta-shaped male plug 3, a third switch 8 for connecting the power line wiring terminal 1 with the 8-shaped male plug 4, and a fourth switch 9 for connecting the power line wiring terminal 1 with the 8-shaped male plug 5; the buttons of the first switch 6, the second switch 7 and the third switch 8 extend outwards through the top of the switching boss 10; the button of the fourth switch 9 penetrates the bottom of the switching boss 10 and extends outwards.
It should be noted that, a conduction circuit may be further disposed in the accommodating cavity to enable different plugs to be conducted. For example, each plug can be conducted with the power line terminal 1 through a switch, so that two plugs can be conducted by closing the two switches simultaneously, and conversion between the plugs is realized. For example, when the first switch 6 and the second switch 7 are both in a closed state, the pin-shaped female plug 2 and the pin-shaped male plug 3 can be conducted, so that the conversion between the two is realized; for another example, when both the first switch 6 and the third switch 8 are closed, the pin-type plug 2 and the 8-type male plug 4 can be turned on, and the switching between the two can be realized.
Further, the button of first switch 6 is located adapter boss 10 top is close to the one end of article letter female plug 2, the button of second switch 7 is located adapter boss 10 top is close to the one end of article letter male plug 3, the button of third switch 8 is located adapter boss 10 top is close to the one end of 8 word male plug 4.
It can be understood that the corresponding relation between the switch and the plug can be judged through the position of the switch, the operation is simple and convenient, and character identification is not needed.
Preferably, the switch is an air switch. Further, the switch is a miniature air switch.
In the multifunctional power adapter provided by the embodiment, the insulating material is a closed insulating shell with strong flame retardant capability, such as imported PVC material. The inside is nested with a conductive material with good conductivity, the conductive material can be nickel-plated phosphor bronze, and the section diameter of the conductive material is generally larger than 4mm 2. The specification, model and size of each plug meet the national standard requirements. The delta-shaped plug and the 8-shaped plug can be conducted with the power line wiring terminal 1 through the switch, and the condition that the total station direct current system fails due to the fact that the unused plug is grounded or short-circuited is avoided.
The multifunctional power adapter provided by the embodiment has the following advantages:
①, it realizes the conversion of many common switch sockets, and increases the selectivity of team to the switch power line and even the switch model, for the condition that the external power supply loop outside the substation is fixed.
② is made of material with good insulating and flame-retardant properties, has high safety and is suitable for long-term use in the electromagnetic environment of a transformer substation.
③ is light and convenient, has high compatibility, various and flexible function conversion, can improve the working efficiency of teams and groups, can control the on-off of unused plugs through a small switch, and has high safety performance.
