A fixable network plug

Abstract

A fixable network plug includes a crystal plug, a fixing sleeve, and a network cable. The fixing sleeve has protrusions on its left and right sides and snap fasteners on its upper and lower sides. At least one of the snap fasteners has a cantilever connection. The fixing sleeve is inserted into the mounting position of a plug mounting plate of a high-voltage switchgear. The protrusions and snap fasteners are located on both sides of the mounting position and provide positioning. The crystal plug is fixed inside the fixing sleeve, and the network cable passes through the inner cavity of the fixing sleeve and connects to the crystal plug. This invention provides a fixable network plug that avoids external network cabling and improves connection reliability.

Description

Technical Field

[0001] The invention belongs to the field of high-voltage switch equipment and relates to a network plug used for a secondary plug socket. Background Art

[0002] Secondary plug sockets are commonly used in the control equipment of existing high-voltage switchgear to control the operating mechanism of the switchgear. Informatization and intelligence are the development direction of high-voltage switchgear, and relying on Internet technology is an important way to realize the informatization transformation of equipment. The secondary plug sockets widely used in existing switchgear were designed 20 to 30 years ago, and no network interface is set. Informatization transformation can only be achieved by adding external ports, which is neither beautiful nor reliable. Summary of the invention

[0003] In order to overcome the disadvantages of the existing information-based transformation method of high-voltage switchgear, which is neither aesthetically pleasing nor reliable, the present invention provides a fixable network plug which avoids externalization of network lines and improves the reliability of connection.

[0004] The technical solution adopted by the present invention to solve its technical problem is:

[0005] A fixable network plug comprises a crystal plug, a fixing sleeve and a network cable, the left and right sides of the fixing sleeve are provided with bosses, the upper and lower sides of the fixing sleeve are provided with buckles, at least one of the two buckles is provided with a cantilever connection, the fixing sleeve is plugged into an installation position of a plug mounting plate of a high-voltage switch device, the bosses and the buckle are respectively located on both sides of the installation position and realize positioning; the crystal plug is fixed in the inner cavity of the fixing sleeve, and the network cable passes through the inner cavity of the fixing sleeve and is connected to the crystal plug.

[0006] Preferably, the crystal plug is crimped onto the network cable as an insert, and then a fixing sleeve is cast in a mold to form an integral, non-detachable, fixable network plug.

[0007] Furthermore, the inner wall of the fixing sleeve is provided with an inner boss and an inner buckle, the inner buckle is provided with a cantilever connection, the tail of the crystal plug abuts against the inner boss, the square hole of the crystal plug is hooked by the inner buckle, and the buckle end of the crystal plug abuts against the inner wall of the fixing sleeve.

[0008] The installation position is an installation hole. Preferably, the installation hole is a square hole.

[0009] The mounting hole is provided with a positioning piece that cooperates with the boss and the buckle. The positioning piece can also be in the form of a boss structure.

[0010] The beneficial effects of the present invention are mainly manifested in: 1. It avoids externalization of network lines and improves the reliability of connection; 2. The two designs of fixable network plugs each have their own advantages, and the overall structure is suitable for large-scale wiring in factories, and the latter is also suitable for on-site wiring construction. BRIEF DESCRIPTION OF THE DRAWINGS

[0011] Figure 1 is a schematic diagram of a fixable network plug.

[0012] Figure 2 is a cross-sectional view of a fixable network plug. DETAILED DESCRIPTION

[0013] The present invention will be further described below in conjunction with the accompanying drawings.

[0014] Reference Figure 1 and Figure 2 A fixable network plug comprises a crystal plug 1, a fixing sleeve 2 and a network cable 3, the left and right sides of the fixing sleeve are provided with bosses 21 and 23, the upper and lower side buckles 22 and 24 of the fixing sleeve, at least one of the buckles 22 and 24 is provided with a cantilever connection, the fixing sleeve is plugged into the installation position of the plug mounting plate 4 of the high-voltage switchgear, the bosses 21 and 23 and the buckles 22 and 24 are respectively located on both sides of the installation position and realize positioning; the crystal plug 1 is fixed in the inner cavity of the fixing sleeve 2, and the network cable 3 passes through the inner cavity of the fixing sleeve 2 and is connected with the crystal plug 1.

[0015] Furthermore, the crystal plug 1 is crimped onto the network cable 3 as an insert, and then a fixing sleeve is cast in a mold to form an integral, non-detachable and fixable network plug.

[0016] Furthermore, the inner wall of the fixing sleeve 2 is provided with an inner boss 25 and an inner buckle 26, the inner buckle 26 is provided with a cantilever connection, the tail of the crystal plug 1 abuts on the inner boss 25, the square hole 12 of the crystal plug 1 is hooked by the inner buckle 26, and the end of the buckle 11 of the crystal plug abuts on the inner wall of the fixing sleeve 2. This is a preferred fixing solution.

[0017] The installation position is an installation hole. Preferably, the installation hole is a square hole.

[0018] The mounting hole is provided with a positioning piece that cooperates with the boss and the buckle. The positioning piece can also be in the form of a boss structure.

[0019] When in use, the fixed network plug is inserted into the square hole 41 of the plug mounting plate 4 of the high-voltage switch device from the right side. When the buckles 22 and 24 pass through the square hole 41, the cantilever of the buckle 24 bends, and after passing through, it opens elastically to hook the plug mounting plate 4, and fixes the network plug together with the bosses 21 and 23; and the buckle 11 of the crystal plug 1 is in a pressed down state, and the removal of the secondary plug is not affected.

[0020] After the network cable 3 is passed through the fixing sleeve 2 and crimped with the crystal plug 1, the crystal plug buckle 11 is pressed and pushed into the fixing sleeve. The lower end of the crystal plug presses down the inner buckle 26 of the cantilever and pushes it to the tail to abut against the inner boss 25. At this time, the inner buckle 26 elastically resets and hooks the square hole 12, realizing the connection of the crystal plug in the fixing sleeve, forming a split assembly structure that can be fixed to the network plug.
