Description

Technical Field

[0001] The invention belongs to the technical field of power electronics, and in particular relates to a fixing mechanism for a socket sealing cover, which is suitable for fixing the socket sealing cover in an outdoor strong impact environment when a plug and socket are in an inserted state. Background Art

[0002] The conventional method of fixing the sealing cover of the electrical connector is to fix the sealing cover to the mounting screw of the socket through a fixing ring or a fixing plate with a stainless steel twist chain, such as Figure 1 This type of sealing cover fixing method is usually used indoors, and is used on sockets that need protection, such as product detection ports or software upgrade ports. It is not suitable for use when the plug and socket are in a plugged-in state for a long time.

[0003] This fixing method has two disadvantages when used outdoors: 1. Before the plug and socket are inserted, the sealing cover must be removed from the socket first. Since the sealing cover has nowhere to be fixed and is suspended in the air, the fixing ring or fixing plate may easily fall off and be lost under strong impact conditions; 2. The installation of the fixing ring or fixing plate has certain requirements on the space around the socket. When the plug and socket are inserted, the sealing cover with the twist chain has no fixed space and swings freely, which will interfere with other parts and affect the use of the product.

[0004] It is necessary to design a new type of fixing mechanism suitable for the metal sealing cover of the outdoor plug and socket in the long-term plug-in state, and at the same time adapt to the use environment with strong impact. Summary of the invention

[0005] 1. Technical issues to be resolved

[0006] The technical problem to be solved by the present invention is: how to design a new type of fixing mechanism for a metal sealing cover to solve the problem that the metal sealing cover of a traditional electrical connector cannot be fixed and is easy to be lost in the plugged state.

[0007] (II) Technical solution

[0008] In order to solve the above technical problems, the present invention provides a fixing mechanism for a socket sealing cover, the fixing mechanism comprising a socket and a metal sealing cover, two symmetrical cylindrical support rods are arranged on the side of the base of the socket, and two symmetrical mounting holes are arranged on both sides of the metal sealing cover;

[0009] Through the matching relationship between the mounting hole of the metal sealing cover and the supporting rod, the metal sealing cover is sleeved onto the supporting rod of the socket base, and a tight fit with the supporting rod is achieved through the rubber gasket in the mounting hole.

[0010] The mounting hole is used to fit and fix with the support rod. On the one hand, the support rod provides a threading hole for the steel wire rope of the sealing cover, and on the other hand, the sealing cover is fixed by passing through the mounting hole.

[0011] Among them, the outer diameter of the left and right support rods is thicker near the socket and thinner away from the socket. The depth of the thick outer diameter part of the support rod is equivalent to the depth of the plug-in part of the sealing cover, ensuring that the sealing cover can be completely inserted into the support rod without interfering with the socket; the depth of the thin outer diameter part of the support rod is higher than the thickness of the sealing cover mounting hole. After fixing the sealing cover, a certain amount of movable margin is left in the front and back to ensure that the sealing cover will not completely loosen on the support rod.

[0012] The length of the thick and thin parts of the outer diameters of the left and right support rods can be designed according to the depth of the plug-in part of the sealing cover and the thickness of the mounting hole of the sealing cover.

[0013] Among them, a boss is provided at the front end of the support rod, and a rubber gasket is provided in the mounting hole of the sealing cover;

[0014] Since the silicone rubber material has a certain degree of stretchability, the outer diameter of the boss is larger than the inner diameter of the rubber gasket, ensuring the close fit between the sealing ring and the support rod. In a strong impact environment, the sealing cover can be reliably fixed and is not easy to fall out.

[0015] Among them, the shell material of the mechanism is high-strength aluminum alloy material, and the surface is treated by mechanical polishing, anodizing, and chemical nickel plating to ensure that the product has certain corrosion resistance and mildew and salt spray resistance.

[0016] Among them, the support rod of the cylinder and the main body of the socket base are designed by welding technology, and the sealing cover mounting hole and the sealing cover main body are designed by integral molding technology.

[0017] Among them, all the edges and corners in the mechanism are processed with sharp edge rounding and chamfering to ensure that the operator will not be injured during use.

[0018] Among them, the metal sealing cover and the socket are fixed by both steel wire rope and left and right support rods. The sealing cover is inserted into the cylindrical support rod on the side of the socket base, which solves the problem of the sealing cover being easily lost due to improper placement.

[0019] Among them, when the plug and socket are in the non-inserted state, the sealing cover is removed from the support rod and directly plugged into the socket to achieve sealing protection for the socket.

[0020] (III) Beneficial effects

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] The invention has a simple principle, novel design, space saving and easy installation, and has been used in batches in a certain foreign trade project. The fixing mechanism can be used in both the plug and socket state and the non-plug state, meeting the use environment with strong impact, without affecting the normal use of the socket, and without changing the overall structure of the socket, thus meeting the application requirements. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Figure 1 It is a schematic diagram of the prior art.

[0024] Figure 2-Figure 4 It is a schematic diagram of the technical solution of the present invention.

[0025] Among them, 1: mounting hole; 2: support rod; 3: boss at the front end of the support rod; 4: rubber gasket in the mounting hole of the sealing cover; 5: wire rope; 6: rod part of the support rod. DETAILED DESCRIPTION

[0026] In order to make the purpose, content, and advantages of the present invention more clear, the specific implementation methods of the present invention are further described in detail below in conjunction with the accompanying drawings and examples.

[0027] In order to solve the above technical problems, the present invention provides a fixing mechanism for a socket sealing cover, such as Figure 2 As shown, the fixing mechanism comprises a socket and a metal sealing cover, two cylindrical support rods are arranged on the side of the base of the socket, and two installation holes are arranged on both sides of the metal sealing cover;

[0028] Through the matching relationship between the mounting hole of the metal sealing cover and the supporting rod, the metal sealing cover is sleeved onto the supporting rod of the socket base, and a tight fit with the supporting rod is achieved through the rubber gasket in the mounting hole.

[0029] The mounting hole is used to fit and fix with the support rod. On the one hand, the support rod provides a threading hole for the steel wire rope of the sealing cover, and on the other hand, the sealing cover is fixed by passing through the mounting hole.

[0030] The outer diameter of the left and right support rods is thicker near the socket and thinner away from the socket. Figure 3 It can be seen that the depth of the thick outer diameter part of the support rod is equivalent to the depth of the sealing cover insertion part, ensuring that the sealing cover can be completely inserted into the support rod without interfering with the socket; the depth of the thin outer diameter part of the support rod is higher than the thickness of the sealing cover mounting hole, and a certain amount of movable margin is left before and after fixing the sealing cover to ensure that the sealing cover will not completely loosen on the support rod.

[0031] The length of the thick and thin parts of the outer diameters of the left and right support rods can be designed according to the depth of the plug-in part of the sealing cover and the thickness of the mounting hole of the sealing cover.

[0032] Among them, a boss is provided at the front end of the support rod, and a rubber gasket is provided in the mounting hole of the sealing cover;

[0033] Since the silicone rubber material has a certain degree of stretchability, the outer diameter of the boss is approximately 0.2 mm larger than the inner diameter of the rubber gasket, ensuring the tight fit between the sealing ring and the support rod. In a strong impact environment, the sealing cover can be reliably fixed and is not easy to fall out.

[0034] Among them, the shell material of the mechanism is high-strength aluminum alloy material, and the surface is treated by mechanical polishing, anodizing, and chemical nickel plating to ensure that the product has certain corrosion resistance and mildew and salt spray resistance.

[0035] Among them, the cylindrical support rod and the socket base body are welded, and the sealing cover mounting hole and the sealing cover body are integrated into an integral molding process. The process technology is mature and the cost is low.

[0036] Among them, all the edges and corners in the mechanism are processed with sharp edge rounding and chamfering to ensure that the operator will not be injured during use.

[0037] in, Figure 3 The schematic diagram shows the principle of fixing the metal sealing cover when the plug and socket are plugged in. Figure 3 It can be seen that the metal sealing cover and the socket are fixed by both steel wire rope and left and right support rods. The sealing cover is inserted into the cylindrical support rod on the side of the socket base, which solves the problem of the sealing cover being easily lost due to improper placement.

[0038] in, Figure 4 The schematic diagram shows the principle of fixing the metal sealing cover when the plug and socket are not plugged in. The sealing cover is removed from the support rod and directly plugged into the socket to achieve sealing protection for the socket.

[0039] Example 1

[0040] This embodiment proposes a safe, reliable, easy to install, low-cost fixing mechanism for socket sealing covers suitable for outdoor strong impact environments. The principle is simple, the design is novel, the application is convenient, and it has a certain degree of originality. The key points are as follows:

[0041] 1) Figure 3 In the mechanism shown, the metal sealing cover is fixed to the socket by two methods: a steel wire rope and passing through a support rod;

[0042] 2) There is a 0.2mm deviation between the outer diameter of the boss at the front end of the left and right support rods and the inner diameter of the silicone rubber sealing ring in the sealing cover installation hole to ensure that the sealing cover is fixed on the support rod and is not easy to fall off;

[0043] 3) The outer diameter of the left and right support rods is thinner in the front and thicker in the back. The length of the thick and thin parts can be designed according to the depth of the sealing cover insertion part and the thickness of the sealing cover installation hole.

[0044] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
