Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a 15kV environmental protection cabinet integrated node connector. Background Technology

[0002] With the increasing demands for power supply reliability due to societal development, more and more emergency power supply equipment is being used by power departments. Among these, emergency generator vehicles and bypass operation vehicles are the most commonly used power supply equipment. These vehicles typically connect to the distribution network in two ways: one is by connecting to overhead lines, and the other is by connecting to high-voltage switchgear or cable distribution boxes. However, connecting power supply vehicles to high-voltage switchgear or distribution boxes requires on-site fabrication and installation of cable joints, which is not only time-consuming and labor-intensive, but also raises concerns about installation reliability, potentially leading to unreliable equipment operation or even safety accidents.

[0003] Existing quick connectors have a simple and singular sleeve structure, and are generally manufactured directly to standard sizes according to orders or market demands. However, the entire connector has multiple components. While the existing one-piece connector body has the characteristic of being integrated, it can easily lead to significant inventory pressure and finished product backlog for factories if they produce in advance to meet order demands. On the other hand, producing only after receiving orders can easily cause delays in use. In addition, quick connectors are often used for emergency and short-term connections, so they are subject to frequent plugging and unplugging compared to ordinary connectors. Consequently, the conductive rods and insulation parts of the socket head on the outside of the cabinet are more prone to damage under frequent plugging and unplugging, affecting product use. Therefore, there is a need to design an integrated node connector that allows for the separate assembly and use of the main body. Utility Model Content

[0004] In view of the existing technology, the purpose of this utility model is to provide a structure for a 15kV environmentally friendly integrated node connector that is convenient for production, assembly and use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a 15kV environmental protection cabinet integrated node connector, including an insulating sleeve, a conductive rod is provided inside the insulating sleeve, and a skirt is provided on the outside of the insulating sleeve.

[0006] The mounting component includes a mounting plate and a protective sleeve, wherein the protective sleeve is threaded to one side of the mounting plate and clamps and fixes the insulating sleeve.

[0007] A protective cap is fitted over the protective sleeve and has an insulating plug on it. A locking assembly is provided between the protective cap and the protective sleeve.

[0008] The detachable plug has a connector with one end electrically connected to a conductive rod and a plug rod with a socket at the other end. The plug rod has an insulating resin layer on the outside and a fixing hole groove on the insulating resin layer for installation and fixation relative to the insulating sleeve.

[0009] As a further feature of the above solution, the protective cap includes a rear protective shell and a plug that is threadedly connected and fixed to the rear protective shell. The plug is threadedly connected and fixed to the rear protective shell, and an installation cavity is formed therein for fastening the insulating plug.

[0010] As a further feature of the above solution, the protective sleeve is provided with a pressure sleeve and a retaining ring groove. The retaining ring groove is located on the outside of the pressure sleeve, and a retaining spring is elastically fastened in the retaining ring groove to prevent the pressure sleeve from disengaging from the protective sleeve.

[0011] As a further feature of the above solution, the locking assembly includes a top spring and locking balls, the protective sleeve is provided with a ball groove, and the pressure sleeve is provided with a clearance groove.

[0023] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, where there is no conflict, the embodiments and features described in these embodiments can be combined with each other.

[0024] like Figure 1-4 The 15kV environmental protection cabinet integrated node connector shown includes an insulating sleeve 1, and a conductive rod 2 is provided inside the insulating sleeve 1. In this embodiment, the conductive rod 2 and the insulating sleeve 1 are manufactured by coating the outside of the conductive rod 2 with resin in a liquid state, and then cooling the resin to solidify it while applying high pressure to make it firmly coated. The prepared insulating sleeve 1 is formed by coating the conductive rod 2 with epoxy resin with insulating properties to form an electrical connector. Furthermore, a skirt 3 is provided on the outside of the insulating sleeve 1. The skirt 3 plays a role in enhancing insulation performance, waterproofing and anti-fouling, and dispersing electric field.

[0025] In this embodiment, the connector is equipped with mounting component 5. The function of mounting component 5 is to connect and install the connector to the power equipment board. During use, as... Figure 4 A suitable thickness mounting plate 51 is selected to mate with mounting posts with internal threads spaced on the other side of the plate. Then, mounting bolts are passed through the holes on the mounting plate 51 and the holes on the power equipment plate, and the mounting posts are connected by threaded engagement, thereby pressing and fixing the connector to the power equipment plate. It is worth noting that the ends of the mounting posts and the outer rings of the mounting holes on the mounting plate 51 are provided with silicone sealing rings (not shown in the figure) to seal and isolate the mounting holes. It is worth noting that the connector in this embodiment is used on an environmental protection cabinet. Therefore, when it is installed relative to the cabinet body, the connection between the two parts and the installation between it and the cabinet body are clamped and sealed with sealant to ensure its use.

[0026] Furthermore, the main structure of the mounting component 5 is a protective sleeve 52 that is threadedly connected to the mounting plate 51. The threaded connection between the protective sleeve 52 and the mounting plate 51 forms a clamping mechanism for the corresponding annular edge of the insulating sleeve 1, and a sealing structure is provided on the clamping end face to form a sealed isolation. Further, as... Figure 4 As shown, the protective sleeve 52 is provided with a pressure sleeve 54 and a retaining ring groove 55. The retaining ring groove 55 is located outside the pressure sleeve 54, and a retaining spring 56 is elastically fastened inside the retaining ring groove 55 to restrict the pressure sleeve 54 from disengaging from the protective sleeve 52. After the retaining spring 56 is engaged in the retaining ring groove 55, its maximum outer diameter is larger than the inner diameter of the pressure sleeve 54, and based on the axial limiting of the retaining ring groove 55, the axial disengagement of the pressure sleeve 54 is limited. Figure 4 As shown, the protective cap 6 in this embodiment is fitted over the protective sleeve 52. The protective cap 6 has an insulating plug 61. A locking assembly 7 is provided between the protective cap 6 and the protective sleeve 52. The inner side of the pressure sleeve 54 also has a stepped surface. A top spring 71 is provided on the stepped surface and the outer stepped surface of the protective sleeve 52. The top spring 71 pushes the pressure sleeve 54 outward based on its own deformation recovery elasticity. The protective sleeve 52 and the pressure sleeve 54 are respectively provided with a ball groove 73 and a clearance groove 74. The ball groove 73 connects to the inner side of the protective sleeve 52. The diameter of the insert 63 of the protective cap 6 is smaller than the inner diameter of the protective sleeve 52. Therefore, when the insert 63 is inserted into the protective sleeve 52, it is located inside it. The insert 63 is provided with a limiting groove. When the limiting groove and the ball groove 73 are opposite each other, the locking ball 72 in the ball groove 73 is pushed into the limiting groove by the outer pressure sleeve 54. At this time, the pressure sleeve 54 abuts against the radially outer side of the locking ball 72. Thus, after the locking ball 72 is radially locked into the limiting groove, it forms an axial locking limit on the insert 63. When the pressure sleeve 54 is pushed inward by the operator to make the groove 74 face the ball groove 73, the locking ball 72 can be made to move radially outward. Thus, when the insert 63 is pulled outward, the locking ball 72 can be driven to disengage from the limiting groove, and the insert 63 can be smoothly disengaged. Based on the elastic force of the top spring 71, after the operator releases the pressure sleeve 54, it returns to the locked state until the next force is applied to the pressure sleeve 54.

[0027] Furthermore, in this embodiment, the detachable plug 8 has a connector 81 with one end electrically connected to the conductive rod 2, and a plug rod 83 with a socket 82 at the other end. An insulating resin layer 84 is provided on the outside of the plug rod 83, and a fixing groove 85 is also provided on the insulating resin layer 84 for installation and fixation relative to the insulating sleeve 1. Figure 4 and Figure 5As shown, the detachable plug 8 is fitted with a threaded, detachable protective cap 6. In this embodiment, the detachable plug 8 is connected to the pre-drilled hole on the insulating sleeve 1 via a bolt assembly through a fixing groove 85 provided on the insulating resin layer 84. During installation, one end of the abutment 81 of the plug rod 83 fully abuts against the conductive bolt rod 2. Therefore, the connector in this embodiment can be assembled according to production and usage requirements to adapt to order usage needs. Furthermore, the detachable structure design of the protective cap 6 allows for adaptive adjustment and replacement of the internally clamped insulating plug 61, enabling complete set use. Figure 3 , Figure 4 as well as Figure 5 As shown, the detachable plug 8 can be replaced relative to the main body. The detachable structure allows the plug to be disassembled separately without disassembling the main body. This not only adapts to the structure of external connectors but also allows for quick replacement of the main plug-in part, i.e., the socket part that is prone to damage, facilitating maintenance.

[0028] As a further provision of the above solution, the protective cap 6 includes a rear protective shell 62 and a plug 63 that is threadedly connected and fixed to the rear protective shell 62. In this embodiment, the plug 63 is threadedly connected and fixed to the rear protective shell 62, and an installation cavity is formed therein for fastening the insulating plug 61. The insulating plug 61 is clamped and installed by the rear protective shell 62 and the plug 63. As mentioned above, the insulating plug 61 can be quickly replaced according to the selection of the detachable plug 8, and can be adapted to switch to an insulating plug 61 that matches the detachable plug 8.

[0029] As a further feature of the above scheme, the locking assembly 7 includes a top spring 71 and a locking ball 72, the protective sleeve 52 is provided with a ball groove 73, and the protective cap 6 is provided with a clearance groove 74.

[0030] As a further feature of the above solution, the detachable plug 8 is fixed to the insulating sleeve 1 by bolts passing through the fixing hole slot 85 and threaded connection.

[0031] As a further feature of the above solution, the protective cap 6 is provided with anti-slip texture and hanging ring 66. The purpose of the hanging ring 66 is to connect the protective cap 6 to the mounting part 5 by connecting a hanging rope. This is to take into account that the use of quick connectors may involve temporary or short-term use, and insulation sealing may be required after use. Therefore, the protective cap 6 removed before the connector is used is left on the connector to avoid being removed and lost.

[0032] As a further feature of the above solution, the mounting plate 51 is also provided with a sealing groove 511 and a sealing ring 512.

[0033] As a further feature of the above scheme, the mounting component 5 and the protective cap 6 are made of metal, and the conductive rod 2 and the detachable plug 8 are both covered with epoxy resin.

[0034] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of this utility model and its equivalents, this utility model also intends to include these modifications and variations.
