[0001] This utility model relates to the field of connector technology, specifically a compact emergency power connector. Background Technology

[0002] Emergency power connectors are core components for ensuring power continuity in operating environments. They enable rapid access to backup power during grid failures, ensuring uninterrupted operation of critical equipment. To address power continuity in complex environments, emergency power connectors must meet requirements for lightweight design and high protection levels.

[0003] An existing emergency power connector includes a connector body with a receiving cavity, and a mounting plate externally mounted on the connector body. A connector cover is rotatably mounted on one end of the mounting plate to cover the opening of the receiving cavity, thus providing dust and water protection for the terminals inside the cavity. The mounting plate increases the space occupied by the power connector, and the cover is connected to the mounting plate via a rotating shaft, requiring a reserved rotation radius to prevent interference with other components when the cover is opened and closed. Furthermore, the cover must completely cover the opening of the receiving cavity when closed, increasing the overall height of the connector. Therefore, this type of emergency power connector occupies a large space during installation and use, and its structure is relatively dispersed and redundant, thus increasing production and usage costs.

[0004] Therefore, in order to reduce the large space occupied by emergency power connectors during installation and use, and to reduce the cost of mass production and use, it is necessary to provide a compact emergency power connector. Utility Model Content

[0008] Furthermore, the plug includes a plug body for plugging and sealing the opening of the receiving cavity and a cover body disposed on the top of the plug body, and one end of the cover body is provided with a protrusion for easy removal of the plug.

[0009] Furthermore, the outer end of the connector body near the mounting component is recessed inward to form a socket groove, and the cover is fitted onto the mounting component and fixedly engaged with the socket groove.

[0010] Furthermore, a fixing groove is formed on the outer side of the connector body, the fixing groove is located at the end of the socket groove away from the mounting part, and the fixing ring is installed in the fixing groove.

[0011] Furthermore, the connector body is provided with a gripping part, which is located between the fixing groove and the socket groove, and the gripping part is provided with an anti-slip groove.

[0012] Furthermore, the mounting component includes a mounting screw connected to the bottom of the outer terminal, and a first washer, a serrated washer, a second washer, and a mounting nut are sequentially fitted on the mounting screw along the direction away from the connector body.

[0013] Furthermore, the inner terminal is provided with a sealing gasket, the bottom of which abuts against the outer top surface of the metal cap, and the inner and outer rings of the sealing gasket are respectively interference-fitted with the inner terminal surface and the inner sidewall of the accommodating cavity.

[0014] Furthermore, a waterproof gasket is fitted on the outer wall of the outer terminal, and the bottom of the waterproof gasket abuts against the bottom of the receiving cavity.

[0019] The embodiments described below are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0020] refer to Figure 1 , Figure 2 As shown, a compact emergency power connector includes a cylindrical connector body 1. One end of the connector body 1 is connected to a mounting member 2 for mounting the emergency power connector, and the other end of the connector body 1 is open and extends to the opposite end to provide a receiving cavity 3. In this embodiment, the connector body 1 is made of a flame-retardant and thermally conductive composite material.

[0021] Specifically, the receiving cavity 3 is provided with an outer terminal 4, the outer terminal 4 is provided with a receiving cavity 5, the inner sidewall of the receiving cavity 5 is provided with a hollow spring assembly 6, and the center of the receiving cavity 5 is provided with an inner terminal 7; the top of the receiving cavity 5 is provided with a rotating groove 8, the rotating groove 8 is located above the spring assembly 6, the top of the rotating groove 8 is provided with a positioning hole 9 communicating with the rotating groove 8, and the top of the outer terminal 4 is provided with a channel 10 communicating with the rotating groove 8.

[0022] The outer terminal 12 is provided with a rotating groove 8, a channel 10, and a positioning hole 9, all for insertion into the plug of the emergency power connector. In practical applications, the plug has a metal terminal, which is covered by a housing. The outer wall of the metal terminal has a positioning pin that mates with the positioning hole 9. During insertion, simply insert the positioning pin of the plug's metal terminal into the rotating groove 8 through the channel 10, and then rotate the plug until the positioning pin is inserted into the positioning hole 9. This ensures a secure connection between the emergency power connector and the plug, facilitating a locking connection. At this time, the housing is inserted into the outer periphery of the outer terminal 12.

[0023] The outer wall of the outer terminal 4 is fitted with a waterproof gasket 11, and the bottom of the waterproof gasket 11 abuts against the bottom of the receiving cavity 3.

[0024] When the emergency power connector and plug are in use, the sleeve on the plug can form an interference fit with the outer wall of the waterproof gasket 11, thereby preventing external moisture from entering the inner terminal 7 and thus achieving a waterproof function.

[0025] The bottom of the inner terminal 7 is provided with a metal cap 12, and a return spring 13 is provided inside the metal cap 12. One end of the return spring 13 is connected to the bottom wall of the accommodating cavity 5, and the other end is connected to the inner wall of the metal cap 12.

[0026] The reset spring 13 can reset the inner terminal 7. When the metal terminal is plugged in, it presses the inner terminal 7 to move downward, so that the reset spring 13 is in a compressed state. Then, the plug is rotated in the rotating groove 8 until the positioning pin reaches the bottom of the positioning hole 9. The reset spring 135 is reset, so that the positioning pin is inserted into the positioning hole 9, thereby making the emergency power connector and the plug firmly connected.

[0027] The inner terminal 7 is covered with a sealing gasket 14. The bottom of the sealing gasket 14 abuts against the outer top surface of the metal cap 12, and the inner and outer rings of the sealing gasket 14 are respectively interference-fitted with the surface of the inner terminal 7 and the inner sidewall of the accommodating cavity 5.

[0028] The sealing gasket 14 can provide elastic cushioning for the metal terminals into which the plug is inserted, and seal the gap between the receiving cavity 5 and the inner terminal 7.

[0029] The opening of the receiving cavity 3 is provided with a pluggable plug 15, and the connector body is covered with a fixing ring 16, and the fixing ring 16 and the plug 15 are fixedly connected by a connecting strip 17.

[0030] In this embodiment, the plug 15 is an elastic plug; the fixing ring 16 is an elastic fixing ring; and the connecting strip 17 is an elastic connecting strip. The plug 15, the fixing ring 16, and the connecting strip 17 are integrally formed and are all made of the same material, such as rubber.

[0031] The plug 15 closes the opening of the receiving cavity 3 without a complex locking mechanism, simplifying operation and reducing additional locking components, thereby lowering production costs and required workspace. The flexible plug fits the opening of the receiving cavity 3 better, effectively preventing dust, moisture, and other foreign objects from entering. Simultaneously, the flexible design makes inserting and removing the plug 15 easier. The connecting strip 17 physically connects the plug 15 to the retaining ring 16, preventing the plug 15 from being lost after removal. The flexible connecting strip can be bent freely, allowing for flexible placement; it can deform to place the plug 15 in unused space, reducing its footprint.

[0032] The plug 15 includes a plug body 151 for plugging and sealing the opening of the receiving cavity 3 and a cover body 152 disposed on the top of the plug body 151, and one end of the cover body 152 is provided with a protrusion 153 for easy removal of the plug 15.

[0033] The mounting component 2 is provided with a cover 18 on the outside, and the outer surface of the cover 18 is provided with anti-slip ridges 19; the cover 18 is sleeved on the mounting component 2 and is fixedly connected to one end of the connector body 1.

[0034] By setting the cover 18 to be fitted onto the mounting part 2 and connected to the connector body 1, the damage caused by bumps between the mounting parts 2 of each connector during the packaging or transportation of the emergency power connector is effectively avoided. This also prevents the mounting part 2 from being affected by external corrosion, dust or moisture before use, thus effectively protecting the mounting part 2, which helps to extend the shelf life of the mounting part 2 and maintain its quality stability.

[0035] Wherein, the outer side of the end of the connector body 1 near the mounting part 2 is recessed inward to form a socket groove 20, and the cover 19 is sleeved on the mounting part 2 and is sleeved and fixed with the socket groove 20.

[0036] A fixing groove (not shown in the figure) is formed on the outer side of the connector body 1. The fixing groove is located at the end of the socket groove 20 away from the mounting part, and the fixing ring 16 is installed in the fixing groove.

[0037] The connector body 1 is provided with a gripping part 21, which is located between the fixing groove and the socket groove 20, and the gripping part 21 is provided with an anti-slip groove 22. The gripping part 21 facilitates the user to grip the connector body 1 to install or remove the emergency power connector. The anti-slip groove 22 significantly increases friction through its surface texture, reducing the risk of slippage and maintaining grip stability. Preferably, the fixing ring 16 and the gripping part 21 are integrally formed.

[0038] The mounting component 2 includes a mounting screw 201 connected to the bottom of the outer terminal 4, and a first washer 202, a serrated washer 203, a second washer 204 and a mounting nut 205 are sequentially sleeved on the mounting screw 201 in the direction away from the connector body 1.

[0039] In practical use, one installation method is as follows: After removing the second washer 204 and the mounting nut 205, insert one side of the mounting hole of the mounting bracket at the end of the mounting screw 201, so that the serrated washer 203 fits against the surface of the mounting bracket outside the mounting hole. Then, install the second washer 204 and the mounting nut 205 sequentially from the other side of the mounting hole to the end of the mounting screw 201, and then tighten the mounting nut 205. During the tightening process, the preload is transmitted to the washer assembly through the mounting nut 205. The serrated tips of the serrated washer 203 undergo slight plastic deformation and come into close contact with the surface of the mounting bracket to form a mechanical engagement, effectively preventing loosening.

[0040] In some embodiments, the sidewall of the receiving cavity 3 includes an inner sidewall and an outer sidewall sleeved on the outer periphery of the inner sidewall and connected to the inner sidewall; the thickness of the outer sidewall is 2-3 times the thickness of the inner sidewall; a plurality of thermally conductive graphite strips are embedded on the side of the outer sidewall near the inner sidewall, and the thermally conductive graphite strips abut against the side of the inner sidewall near the outer sidewall; a graphite thermally conductive sheet layer is provided on the surface of the inner sidewall away from the outer sidewall.

[0041] A graphite heat-conducting layer is installed on the inner side wall of the receiving cavity 3, away from the outer side wall. This effectively absorbs and conducts heat generated by the inner terminals 7 and outer terminals 4 within the connector, rapidly transferring it to the outer side wall. The heat-conducting graphite strips on the outer side wall significantly enhance its heat dissipation performance and efficiency, quickly transferring the conducted heat to the outside of the receiving cavity 3, and even to the outside of the connector body 1. This achieves efficient heat dissipation for the emergency power connector, extending its service life and improving its reliability and stability. Furthermore, since the thickness of the outer side wall is 2-3 times that of the inner side wall (meaning the inner side wall is much thinner than the outer side wall), heat inside the connector can be quickly conducted to the heat-conducting graphite strips on the outer side wall and rapidly dissipated under their influence.

[0042] This utility model provides a compact emergency power connector. The connector body 1 adopts a cylindrical design, and a fixing ring 16 is fixedly installed on the outer sleeve of the connector body 1. The fixing ring 16 is connected to the plug 15 through the connecting strip 17, and the plug 15 closes the opening of the receiving cavity 3 of the connector body 1, thereby providing waterproof and dustproof protection for the inside of the receiving cavity 3. Compared with the prior art, there is no need to set up a space-consuming mounting plate to cooperate with the cover to close the receiving cavity. The plug-and-play setting of the plug 15 and the connection design of the connecting strip 17 also make it possible to open and close the opening of the receiving cavity 3 without reserving the rotation radius space of the cover to prevent interference from other components. This makes the emergency power connector simple and compact in structure, occupies little space during use, and helps to reduce production costs.

[0043] The above-disclosed embodiments are merely some preferred embodiments of the present utility model, and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the present utility model patent application shall still fall within the scope of the present utility model.
