Description

Technical Field

[0001] This invention relates to the field of cable plug technology, and more particularly to an aviation plug with self-locking and testing functions. Background Technology

[0002] With the development of power grids and the advancement of smart grid construction, the number of outdoor smart devices in power grids is increasing. Currently, smart device control cabinets are widely used in substations. Because these cabinets integrate intelligent component units, smart terminals, and energy meters, the number of terminal blocks and their wiring within the cabinets has increased significantly. This leads to messy wiring and even situations where cable trays cannot be properly covered. Therefore, new connection methods are needed to replace traditional terminal block wiring methods, thereby solving problems such as accidental contact and incorrect wiring.

[0003] In existing technologies, to address issues such as accidental contact and wiring errors within intelligent device control cabinets, aviation plugs are used as a novel plug-and-play connection method for secondary equipment. This method offers advantages such as good environmental adaptability, secure connection, convenience, high conductivity, and small footprint. However, aviation plugs are prone to safety hazards during long-term operation, including loosening, poor contact, deformation, and open circuits. If these hazards cannot be promptly eliminated, they can pose a significant threat to the safe and stable operation of the power grid. Therefore, it is necessary to provide a new aviation plug to prevent these safety hazards. Summary of the Invention

[0004] The technical problem to be solved by the embodiments of the present invention is to provide an aviation plug with self-locking and testing functions, which can prevent safety hazards such as loosening, poor contact, deformation and open circuit.

[0005] To address the aforementioned technical problems, embodiments of the present invention provide an aviation connector with self-locking and testing functions, comprising a male connector, a female connector, and multiple conductive self-locking pins; wherein,

[0006] The male connector's housing has a recessed groove on one end face facing the female connector. The bottom wall of the groove has multiple conductive pins, and its side walls have multiple hollow holes for positioning and multiple male connector test holes. One end of each conductive pin is fixed to the bottom wall of the groove and connected to a corresponding conductor in the cable away from the female connector via an external male connector lead-out wire. The other end of each pin extends a certain length towards the female connector. Each male connector test hole has a first conductive terminal in its center, and each first conductive terminal is connected to the end of a corresponding conductive pin located on the bottom wall of the groove via a conductive wire pre-set inside the male connector's housing.

[0007] The female connector housing has a boss on the end face facing the male connector that mates with the groove; the boss has multiple conductive holes on the end face facing the male connector that mate with multiple conductive pins, and multiple female connector test holes on its sidewall that mate with multiple hollow holes; each conductive hole mates with a corresponding conductive pin and is in the shape of a hollow tube, and each has a wire lug fixed on its end away from the male connector, and each wire lug leads out of the female connector and connects to the corresponding wire in the cable near the female connector; each female connector test hole has a second conductive terminal in the middle, and each second conductive terminal is connected to the wire lug of the corresponding conductive hole through a conductive wire preset in the boss.

[0008] When the male and female connectors are aligned and installed, the protrusion of the female connector is embedded in the groove of the male connector and each conductive pin is inserted into a corresponding conductive hole. Each self-locking bolt is inserted into the corresponding test hole of the female connector through a corresponding hollow hole to achieve locking between the male and female connectors.

[0009] Each self-locking bolt is connected to the second conductive terminal in the corresponding female test hole to form a test end, and each of them cooperates with the first conductive terminal in the corresponding male test hole as another test end.

[0010] The multiple conductive pins in the male connector are arranged in one row or in two staggered rows.

[0011] Among them, the plurality of male test holes and the plurality of female test holes are all blind holes.

[0012] The test end formed by each self-locking pin and its corresponding test end are connected to both ends of an external tester, so as to test the installation status of each conductive pin inserted into a corresponding conductive socket through the external tester.

[0013] The external testing instrument is either a light alarm device or a multimeter.

[0014] Both the first conductive terminal and the second conductive terminal are copper sheets.

[0015] The wire lug is made of copper.

[0016] The cables connected to the multiple conductive pins of the male connector and the cables connected to the multiple wire lugs of the female connector are both large-pair copper core cables.

[0017] Implementing the embodiments of the present invention has the following beneficial effects:

[0018] After the male and female connectors are aligned and installed, the female connector's protrusion is embedded in the male connector's groove, and each conductive pin is inserted into a corresponding conductive socket. By inserting each self-locking bolt through its corresponding hollow hole into the mating female connector's test hole, the male and female connectors are locked together to prevent loosening and other safety hazards. Furthermore, by connecting the test end formed by each self-locking bolt and its corresponding mating test end to the two ends of an external tester, the installation status of the conductive pins inserted into the conductive sockets can be tested, thus providing a testing function and further preventing safety hazards such as loosening, poor contact, deformation, and open circuits.

Detailed Implementation

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0023] like Figure 1 and Figure 2 As shown in the figure, an aviation plug with self-locking and testing functions is proposed in an embodiment of the present invention, including a male connector 1, a female connector 2, and multiple conductive self-locking pins 3; wherein,

[0024] The male connector 1 has a recessed groove 11 on the end face facing the female connector 2. The bottom wall of the groove 11 is provided with a plurality of conductive pins 4 arranged in a row or in two staggered rows, and the side wall is provided with a plurality of hollow holes 111 for positioning and a plurality of male connector test holes 112. Each conductive pin 4 is made of copper, one end of which is fixed to the bottom wall of the groove 11 and is connected to the corresponding wire in the cable (such as a large pair copper core cable, not shown) away from the female connector 2 through an external male connector lead-out wire L1. The other end of each male connector extends a certain length towards the female connector 2. Each male connector test hole 112 is a through hole or a blind hole, and a first conductive terminal T1 (such as a copper sheet) is provided in the middle of each hole. Each first conductive terminal T1 is connected to the end of the corresponding conductive pin 4 located on the bottom wall of the groove 11 through a conductive wire J1 preset in the housing of the male connector 1.

[0025] The female connector 2 has a boss 21 on its end face facing the male connector 1, which mates with the groove 11. This boss 21 has multiple conductive holes 5 on its end face facing the male connector 1, which mate with multiple conductive pins 4. Its sidewall has multiple female connector test holes 211 that mate with multiple hollow holes 111. Each conductive hole 5 is made of copper, mates with a corresponding conductive pin 4, and is in the shape of a hollow tube. The end of each hole 5 away from the male connector 1 is fixed with... There is a wire lug 6 made of copper, and each wire lug 6 has a female lead L2 leading out to connect to the corresponding wire in the cable (such as a large pair copper core cable, not shown) near the female lead 2; each female lead test hole 211 is a through hole or a blind hole, and each of them has a second conductive terminal T2 (such as a copper sheet) in the middle, and each of the second conductive terminals T2 is connected to the wire lug 6 connected to the corresponding conductive socket 5 through a conductive wire J2 preset in the boss 21;

[0026] When the male connector 1 and the female connector 2 are aligned and installed, the protrusion 21 of the female connector 2 is embedded in the groove 11 of the male connector 1, and each conductive pin 4 is inserted into a corresponding conductive socket 5. Each self-locking bolt 3 is inserted into the mating female connector test hole 211 through a corresponding hollow hole 111, so as to lock the male connector 1 and the female connector 2 together.

[0027] Each self-locking pin 3 is connected to the second conductive terminal T2 in the corresponding female test hole 211 to form a test end, and each also mates with the first conductive terminal T1 in the corresponding male test hole 112, which serves as another test end. At this time, the test end formed by each self-locking pin 3 and its corresponding mating test end are connected to the two ends of an external tester (such as a light alarm device or a multimeter) to test the proper insertion of each conductive pin 4 into the corresponding conductive socket 5.

[0028] It is understandable that if the male connector 1 and the female connector 2 are not installed properly, the external tester will not be able to measure the corresponding electrical signal. Therefore, based on the measurement results, the test can be performed to determine whether each conductive pin 4 is properly inserted into the corresponding conductive socket 5.

[0029] In one example, the male connector 1 has a cylindrical shell with a recessed groove 11 formed from the top to the bottom. One or two rows of through holes arranged in an alternating matrix are formed on the bottom wall of the groove 11. Multiple hollow holes 111 for positioning and multiple blind male connector test holes 112 are formed on the side wall of the groove 11. Each conductive pin 4 is fixed to the corresponding through hole by a thread and arranged in an alternating matrix. Each pin is connected to the corresponding conductor in a large-pair copper core cable away from the female connector 2 via an external male connector lead-out wire L1. Each male connector test hole 112 has a first conductive terminal T1 in its center, and each first conductive terminal T1 is connected to one end of a corresponding conductive pin 4 located on the bottom wall of the groove 11 via a pre-set conductive wire J1 inside the shell of the male connector 1.

[0030] Meanwhile, the shell of the female connector 2 is columnar, and a boss 21 is formed on the end face of the male connector 1 to cooperate with the groove 11 of the male connector 1. One or two rows of through holes are also opened on the boss 21 in an alternating matrix pattern and correspond to the through holes on the male connector 1, so that all conductive pins 4 can be inserted into the corresponding conductive sockets 5. The side wall of the boss 21 is provided with multiple blind hole-shaped female connector test holes 211 that cooperate with multiple hollow holes 111.

[0031] At this time, each conductive socket 5 is embedded in a corresponding through hole opened in the female head 2 by means of thread, and a wire lug 6 is fixed at the bottom by welding. A female head wire L2 is led out from the wire lug 6 and connected to the corresponding wire in the large pair copper core cable near the direction of the female head 2. Each female head test hole 211 is provided with a second conductive terminal T2 (such as a metal copper sheet) in the middle, and a conductive wire J2 is preset in the boss 21 and connected to the wire lug 6 connected to the corresponding conductive socket 5 through the second conductive terminal T2.

[0032] When the male connector 1 and female connector 2 are aligned and installed, the protrusion 21 of the female connector 2 is embedded in the groove 11 of the male connector 1, and each conductive pin 4 is inserted into a corresponding conductive socket 5. Each self-locking pin 3 is inserted into the corresponding hollow hole 111 into the mating female connector test hole 211 to lock the male connector 1 and female connector 2 together, thereby giving the aviation connector a self-locking function and preventing the wires from shifting after the male and female connectors are installed.

[0033] In addition, each self-locking pin 3 is connected to the second conductive terminal T2 in the corresponding female connector test hole 211 to form a test end, and each of them mates with the first conductive terminal T1 in the corresponding male connector test hole 112, which serves as another test end. At this time, the test end formed by each self-locking pin 3 and its corresponding mate test end are connected to the two ends of an external tester (such as a light alarm device or a multimeter) to test the installation status of each conductive pin 4 inserted into the corresponding conductive socket 5 through the external tester. This enables the aviation plug to have a testing function, quickly identify whether the male and female connectors are installed correctly, and effectively monitor safety hazards such as looseness, poor contact, deformation, and open circuits online.

[0034] The following is a specific method of using an aviation plug with self-locking and testing functions according to an embodiment of the present invention:

[0035] First stage: After the male connector 1 and female connector 2 are aligned and installed, the self-locking bolt 3 is inserted through the hollow hole 111 into the mating female connector test hole 211 to lock the male connector 1 and female connector 2 together, thereby giving the aviation connector a self-locking function and preventing the wires from shifting after the male and female connectors are installed.

[0036] The second stage: After confirming that the male connector 1 and female connector 2 are installed in place, if the system is running for a period of time or for an extended period of time, connect the test end formed by the self-locking bolt 3 and its corresponding test end to the two ends of an external tester (such as a light alarm device or a multimeter). This allows the external tester to test the installation status of each conductive pin 4 inserted into the corresponding conductive socket 5, thereby enabling the aviation plug to have a testing function, quickly identify whether the male and female connectors are installed in place, and effectively monitor safety hazards such as looseness, poor contact, deformation, and open circuits online.

[0037] Implementing the embodiments of the present invention has the following beneficial effects:

[0038] After the male and female connectors are aligned and installed, the female connector's protrusion is embedded in the male connector's groove, and each conductive pin is inserted into a corresponding conductive socket. By inserting each self-locking bolt through its corresponding hollow hole into the mating female connector's test hole, the male and female connectors are locked together to prevent loosening and other safety hazards. Furthermore, by connecting the test end formed by each self-locking bolt and its corresponding mating test end to the two ends of an external tester, the installation status of the conductive pins inserted into the conductive sockets can be tested, thus providing a testing function and further preventing safety hazards such as loosening, poor contact, deformation, and open circuits.

[0039] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.
