Problems solved by technology

The disadvantages are: due to the need to ensure the airtightness between the metal substrate and the electrical casing, the welding process requires high requirements, and it is easy to cause waste rework; in addition, because the wires in the electrical casing need to be welded and fixed on the inner side of the metal substrate. On the column, it also makes its operation more cumbersome, time-consuming and labor-intensive

Embodiment 1

[0028] Figure 1 to Figure 3 A first embodiment of the invention is shown in which, figure 1 It is a structural schematic diagram of the first structure of the present invention; figure 2 for figure 1 Sectional view along line A-A; image 3 for figure 1 A schematic diagram of the structure of the substrate in the electrical connector shown.

[0029] The present invention is an electrical connector for an inflatable high-voltage electrical appliance, see Figure 1 to Figure 3 , including a rectangular plate-shaped stainless steel substrate 1 provided with mounting holes 13 at four corners and twelve terminal posts 2 arranged on the substrate 1 .

[0030] Twelve circular through-holes 11 are provided on the metal substrate 1, and a groove 12 is provided on both sides of the substrate, and the openings at both sides of each through-hole 11 are located in the corresponding grooves 12; The terminal 2 is located in the center of a corresponding through hole 11 ; an insulating...

Embodiment 2

[0036] Figure 4 It is a structural schematic diagram of the second structure of the present invention, showing the second specific implementation manner of the present invention.

[0037] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 4 , the outer wall of the elastic sealing layer 3 is provided with two annular elastic protruding rings 31 . This structure can further ensure the airtightness between the substrate and the electrical housing.

Embodiment 3

[0039] Figure 5 It is a structural schematic diagram of the third structure of the present invention, showing the third specific implementation manner of the present invention.

[0040] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 5 , both sides of the substrate 1 are fixed with an elastic sealing layer 3 as a sealing surface by injection molding or compression molding, and one end of the same side of the terminal post 2 and the elastic sealing layer 3 protrudes from the elastic sealing layer 3.

[0041] The above embodiments 1 to 3 have positive effects: (1) In the above embodiments 1 to 3, the substrate 1 is provided with a plurality of through holes 11, and each terminal post 2 is located in a corresponding through hole 11; the outer wall of each terminal 2 and the inner wall of the through hole 11 are filled with insulating material to form a ring-shaped insulator 4, and the two ends of each terminal 2 protrude from the ring-shap...

Abstract

The invention discloses an electrical connector for an inflatable high voltage electrical appliance. The electrical connector comprises a base plate with mounting holes and wiring terminals arranged on the base plate. A plurality of through holes are formed on the base plate, and each wiring terminal is positioned in the centers of corresponding through holes. An insulating material is filled between the outer walls of each wiring terminal and the inner walls of the corresponding through holes to form annular insulators. The two ends of each wiring terminal are extended out of the annular insulators as splicing pins. The electrical connector has the advantage that: electrical connection operations are simple, convenient and labor-saving.

Description

technical field [0001] The invention belongs to the technical field of electrical connector structure design, and in particular relates to an electrical connector used for an inflatable high-voltage electrical appliance. Background technique [0002] The existing electrical connectors for SF6 inflatable cabinets and switches on SF6 poles generally include a metal substrate welded and fixed on the electrical appliance casing and a pin-type terminal set on the outer end of the metal substrate located on the outer side of the casing. The electric wires in the shell are welded and fixed on the terminal posts at the inner side of the metal substrate, and each terminal post is insulated from the metal substrate through the sealing resin. The disadvantages are: due to the need to ensure the airtightness between the metal substrate and the electrical casing, the welding process requires high requirements, and it is easy to cause waste rework; in addition, because the wires in the el...
