In order to cope with the power connection in complex environment, the emergency power connector needs to meet the requirements of lightweight and high protection level.

[0003] An existing emergency power connector mainly sets an installation plate outside the connector body, and a connector cover body for shielding the opening of the accommodating cavity is rotatably arranged at one end of the installation plate. A rotation radius space needs to be reserved to prevent the cover body from interfering with other components when opening and closing, resulting in that the emergency power connector occupies a large space during installation and use, and the structure is relatively dispersed and redundant, thereby increasing the production and use cost. At the same time, the emergency power connector will generate heat during use, and excessive heat accumulation will cause problems such as increased contact resistance, corrosion, and affect the quality and stability of current transmission.

DETAILED DESCRIPTION

[0020] The embodiments described below are only part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the application.

[0021] Reference Figure 1 、 Figure 2 As shown in the figure, a compact emergency power connector includes a cylindrical connector body 1, the connector body 1 includes a seat body 101 and a cylindrical shell 102; the seat body 101 is connected with a mounting piece 2 for installing the emergency power connector at one end, and the other end of the seat body 101 is open and extends to the other end to provide a containing cavity 3.

[0022] Specifically, the outer side wall of the seat body 102 is provided with a plurality of groove bodies, and the heat conduction strip 103 is embedded in the groove body; the inner side of the cylindrical shell 102 is embedded with a micro temperature sensor 24 for detecting the temperature of the seat body 101. In this embodiment, the heat conduction strip 103 is a graphite heat conduction strip or a heat conduction silica gel strip.

[0023] The heat-conducting strip 103 effectively absorbs and conducts heat from inside the emergency power connector to the outside, enhancing the heat dissipation performance and efficiency of the emergency power connector. This achieves efficient heat dissipation, extends the connector's service life, and improves its reliability and stability. Preferably, the opening of the groove is provided with several limiting strips 104 for limiting and fixing the heat-conducting strip 103 installed in the groove.

[0024] The miniature temperature sensor 21 includes a sensor body 241 and a power connector 242. The sensor body 241 includes a housing 2411 and a connecting block 2412 mounted on the housing 2411. A thermistor 2413 is provided inside the housing 2411. The thermistor 2413 is fixedly connected to the inner wiring groove of the connecting block 2412 through a resistance wire 2414. The outer wiring groove of the connecting block 2412 is connected to the power connector 242 through a power wire 2415. The power connector 242 penetrates the cylindrical shell 102 and is exposed on the outside. A plurality of heat-conducting columns 2416 are also provided outside the housing 2411. The heat-conducting columns 2416 penetrate the housing 2411 and extend into the interior of the housing 2411. The cylindrical shell 102 is fitted on the outside of the base 101, so that the heat-conducting columns 2416 abut against the heat-conducting strip 103.

[0025] When using the emergency power connector, the power connector 242 is electrically connected to an external data detection device, allowing a constant current to flow sequentially through the power wire 2415, the connecting block 2412, and the resistance wire 2413 into the thermistor 2413. After passing through the thermistor 2413, the constant current is received again by the external data detection device. Meanwhile, the emergency power connector continuously generates heat during operation, which is rapidly dissipated through the heat-conducting strip 103. Because the heat-conducting pillar 2416 abuts against the heat-conducting strip 103, the thermistor 2413 can accurately and quickly sense changes in the external temperature, causing its resistance value to decrease rapidly as the temperature rises. This allows the operating temperature of the emergency power connector at different short intervals to be obtained.

[0026] By using the miniature temperature sensor 24, the temperature changes of the emergency power connector during operation can be acquired in real time, thereby promptly detecting abnormal overheating of the emergency power connector, reducing the occurrence of safety accidents, and helping to extend the service life of the emergency power connector.

[0027] Among them, reference Figure 5 and Figure 6As shown, the outer side of the seat 101 away from the opening is provided with an external thread and a first annular sealing ring 105 is embedded therein; the first annular sealing ring 105 is located on the side of the external thread away from the opening; the outer side of the seat 101 near the opening is provided with a second annular sealing ring 106; the inner side of the cylindrical sleeve 102 is provided with an internal thread that matches the external thread, and the cylindrical sleeve 102 is sleeved on the outer side of the seat 101 and connected to the external thread through the internal thread, so that the inner and outer rings of the first annular sealing ring 105 and the second annular sealing ring 106 abut against the outer side of the seat 101 and the inner side of the cylindrical sleeve 102, respectively.

[0028] The detachable mounting of the base 101 and the cylindrical sleeve 102 facilitates the installation and recycling of the heat-conducting strip 103. The first annular sealing ring 105 and the second annular sealing ring 106 prevent moisture from entering and damaging the heat-conducting strip 103 and the miniature temperature sensor 24.

[0029] One end of the connector body 1 is connected to the mounting piece 2 for installing the emergency power connector, and the other end of the connector body 1 is open and extends to the opposite end, providing a receiving cavity 3. In this embodiment, the connector body 1 is made of a flame-retardant and thermally conductive composite material.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] 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.

[0042] 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.

[0043] 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.

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 along the direction away from the connector body 1.

[0048] In actual use, one of the installation methods is as follows. After removing the second gasket 204 and the mounting nut 205, place one side of the mounting hole of the end mounting bracket of the mounting screw 201 into it, so that the serrated gasket 203 fits against the surface of the mounting bracket outside the mounting hole. Then, install the second gasket 204 and the mounting nut 205 in sequence from the other side of the mounting hole for the end of the mounting screw 201, and then tighten the mounting nut 205. During the tightening process, the pre-tightening force is transmitted to the gasket group through the mounting nut 205. The serrated tips of the serrated gasket 203 undergo a small amount of plastic deformation and get close to the surface of the mounting bracket to form a mechanical bite, effectively preventing loosening.

[0049] The present invention provides a compact emergency power connector. The connector body 1 is designed in a cylindrical shape, and a fixing ring 16 is sleeved and fixed outside the connector body 1. The fixing ring 16 is connected to the plug cover 15 through a connecting strip 17, and the opening of the accommodating cavity 3 of the connector body 1 is closed by the pluggable plug cover 15, thereby playing a role in waterproofing and dustproofing the inside of the accommodating cavity 3. Compared with the prior art, there is no need to set up a mounting plate that occupies a large space to cooperate with the cover body to close the accommodating cavity. The pluggable setting of the plug cover 15 and the connection design of the connecting strip 17 also make it unnecessary to reserve the rotation radius space of the cover body to prevent interference from other components when opening and closing the opening of the accommodating cavity 3. This makes the structure of the emergency power connector simple and compact, occupies a small space during use, and is beneficial to reducing production costs.

[0050] Reference Figure 9 As shown, the present invention also provides a monitoring method for a compact emergency power connector, which is applicable to a compact emergency power connector as described above, and includes: Step S1: Number the N emergency power connectors that enter the working state, and connect their power connectors to an external data detection device. Then, collect the real-time temperature corresponding to each emergency power connector through the external data detection device, and form a temperature data list.

[0051] Step S2: When the number M of real-time temperature data in the temperature data list is less than N, it is confirmed that there is an abnormal temperature data acquisition, and a first warning signal is sent. At this time, there may be a situation such as damage to the micro temperature sensor 24 or abnormal transmission line in the emergency power connector, resulting in the inability to obtain the corresponding temperature data. At this time, a first warning signal is sent to remind the user to check all emergency power connectors. When M = N, each micro temperature sensor 24 is working normally, and step S3 is entered.

[0052] Step S3: Compare the real-time temperature data in the temperature data list with a preset temperature threshold in sequence. When T i ≥ T0, it is confirmed that there is abnormal temperature data, and the number of the corresponding emergency power connector and a second warning signal are output; where T iThis represents the real-time temperature data of the emergency power connector numbered i, where i = 1...N; T0 represents the preset temperature threshold.

[0053] When T i When the temperature reaches ≥T0, abnormal temperature data is confirmed, and a second warning signal needs to be issued to remind the user to check the corresponding emergency power connector. At this time, the preset temperature threshold is the highest temperature at which the emergency power connector can operate normally.

[0054] Step S4: Determine the average temperature T of each real-time temperature data point based on the temperature data list. P and temperature standard deviation T S ; and then obtain the outlier S of the real-time temperature data in the temperature data list. i When |S i When |≥S0, an abnormal temperature is confirmed, and the corresponding emergency power connector number and a third warning signal are output; among which, .

[0055] When |S i When |≥S0, it proves that there is an emergency power connector whose operating temperature is too different from other emergency power connectors of the same type that are working. It can be considered that there is an abnormality and a third warning signal needs to be issued to remind the user to check the emergency power connector with the corresponding number.

[0056] Step S5: After a preset time interval t, re-collect the real-time temperature corresponding to each emergency power connector, obtain a new temperature data list, and repeat steps S2 to S4.

[0057] This invention provides a monitoring method for compact emergency power connectors. By collecting the real-time temperature of each emergency power connector and forming a temperature data list, the method determines whether the working status of each emergency power connector is abnormal based on the temperature data list and provides warnings through different early warning signals. This allows abnormal working status of each emergency power connector to be detected in a timely manner, thereby avoiding damage to the emergency power connectors and their connected devices caused by excessive temperature, significantly improving the safety of emergency power connector use and extending the service life of the connectors.

[0058] In some embodiments, step S5 further includes obtaining the temperature change rate of each emergency power connector within the preset time t based on the new temperature data list and the temperature data list obtained before the preset time t. When the temperature change rate is greater than or equal to the preset change rate or the temperature change rate is equal to 0, it is confirmed that there is abnormal temperature data, and the corresponding emergency power connector number and fourth warning signal are output.

[0059] When the temperature change rate is greater than or equal to the preset change rate or the temperature change rate is equal to 0, it indicates that the temperature change is abnormal and the emergency power connector may be in an abnormal working state. The user will be reminded to check by outputting the corresponding emergency power connector number and the fourth warning signal.

[0060] In this embodiment, the first warning signal, the second warning signal, the third warning signal, and the fourth warning signal can be alerted by different colored indicator lights or different warning sounds, making it easier for users to distinguish the criteria for fault diagnosis, thereby helping users to trace the source of the problem more quickly.

[0061] The monitoring method also includes step S6: after obtaining X temperature data lists, based on each temperature data list and the correspondence between temperature data and time, a time-temperature curve corresponding to each emergency power connector is generated, and the heat dissipation status of each emergency power connector is determined according to the time-temperature curve.

[0062] During use, the difference in heat dissipation status can be obtained by comparing the acquired time-temperature curve with the standard time-temperature curve generated from the temperature data of the emergency power connector under standard conditions. Based on the difference, it can be determined whether external heat dissipation needs to be increased or whether the internal heat dissipation of the emergency power connector is normal. This effectively prevents equipment failures caused by heat dissipation problems, can detect abnormal heat dissipation in a timely manner, improves the stability of emergency power connector use, and extends the service life of the connector.

[0063] The above-disclosed embodiments are merely some preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
