Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] See also Figures 2 to 4 The present invention discloses a connector for a handcart cabinet, comprising a connector housing 1. A compatible socket 2 and a wiring terminal 4 are arranged outside the connector housing 1, and the compatible socket 2 and the wiring terminal 4 are connected by a prefabricated wire 8.

[0026] Among them, the wiring plug-in 7 of the wiring terminal 4 is located in the inner cavity of the connector housing 1, the prefabricated wire 8 is arranged in the inner cavity of the connector housing 1, and the wiring plug-in 7 is connected to the wiring jack 3 on the compatible socket 2 through the prefabricated wire 8. The wiring terminal 4 is the upper wiring terminal, and the compatible socket 2 is the lower wiring terminal. The lower wiring terminal is located in the circuit breaker room of the handcart cabinet, and the upper wiring terminal is located in the instrument room. The circuit breaker room and the instrument room are separated by a partition 10. Different prefabricated wires 8 are fixedly arranged in sequence on the inner cavity wall of the connector housing 1.

[0027] Specifically, the compatible socket 2 is a socket compatible with the existing functional trolley and trolley-type circuit breaker secondary plug. The socket adopts a 75-hole design, which is compatible with the existing 58-hole or 64-hole plugs and can meet more functional expansion requirements; the wiring terminal 4 adopts a three-row 75-position bolt fastening structure of the wiring terminal 4, which is used for secondary wiring connection. The wiring jack 3 is a plug-in connection structure.

[0028] The connector 11 of the present invention uses a prefabricated wire 8 to connect the wiring terminal 4 and the wiring jack 3. The wiring terminal 4 and the wiring jack 3 adopt an integrated structure, replacing multiple separate structures such as the aviation socket 07, the corrugated hose 06, the wire elbow 05 and the guide rail bracket 02 in the existing wiring scheme, so that the wiring structure is simple and reliable; the connector 11 is connected to the partition 10, and the two ends of the wiring pass through the partition 10 and are arranged in the upper and lower chambers. The lower wiring terminal is located in the circuit breaker chamber and the upper wiring terminal is located in the instrument chamber, which greatly reduces the use of connecting wires, simplifies the wiring, and makes the wiring convenient and fast. By setting the prefabricated wire 8 inside the connector 11, the use of wires is reduced, and there is no need to use a wire harness. Since the harness is eliminated, the problem of loose fixation and falling off of the harness in the prior art is avoided, making the wiring reliable; at the same time, the structure of the prefabricated wire 8 is adopted, and the wiring is flexible, and the connected lines can be increased or decreased according to needs, so that the increase or decrease of the lines is not limited by the space of the tube cavity of the corrugated hose 06. The prefabricated conductors 8 are fixedly arranged in sequence on the inner cavity wall of the connector housing 1 , so that each prefabricated conductor 8 can be easily inspected and plugged in.

[0029] Specifically, the surface of the connector housing 1 is provided with a plurality of through holes, the number and position of the through holes correspond to the wiring plug-in 7 of the wiring terminal 4, and the wiring plug-in 7 extends through the through holes into the inner cavity of the connector housing 1 to facilitate connection with the prefabricated wire 8 in the inner cavity of the connector housing 1. The prefabricated wire 8 can be matched according to the number and quantity as required, and can also be replaced and removed at any time.

[0030] In order to prevent the two ends of the prefabricated wire 8 from being connected incorrectly or missing, a serial number is set next to each wiring terminal 4, and a serial number is set next to each wiring plug-in 7, which is the same as the wiring terminal 4 set at the corresponding position, and a serial number is also set next to the wiring jack 3. The prefabricated wire 8 is matched according to the number and quantity as needed, and the corresponding connector of the prefabricated wire 8 can be replaced and removed at any time.

[0031] Furthermore, an opening is provided on the side of the connector housing 1, and the compatible socket 2 is connected to the edge of the opening. The opening is provided corresponding to the hole setting area of ​​the wiring jack 3 of the compatible socket 2, and the correspondence here includes the correspondence of position and size, and the area of ​​the opening is not less than the area of ​​the area where the wiring jack 3 is provided.

[0032] In a specific embodiment, the wiring terminal 4 is located at the top of the connector housing 1, the compatible socket 2 is located on the side of the connector housing 1, the bottom surface of the connector housing 1 is open, and the side corresponding to the side connected to the compatible socket 2 is also open. The bottom surface of the open setting is connected to the side of the open setting to form an L-shaped opening, and the position of the L-shaped opening is provided with an openable cover 6. It can be understood that the cover 6 is also L-shaped. The upper wiring terminal 4 of the connector of the present invention replaces the existing wiring terminal row, and the terminal has a label consistent with the aviation plug, which can be directly connected to the secondary control circuit. The wiring is clear at a glance, ensuring correct wiring, and convenient inspection and calibration. When the connector has a wiring error, open the cover 6 of the connector 11, and directly measure and observe without disassembling the main structure. It can be seen that the L-shaped cover 6 is convenient for internal wiring and maintenance after opening, and can achieve electrical isolation from the high-voltage part in the cabinet after buckling.

[0033] In order to facilitate connection and disassembly, one end of the prefabricated wire 8 is crimped with a pre-insulated spring terminal and the other end is crimped with a pin. The pre-insulated spring terminal is connected to the wiring plug-in 7, and the pin is plugged into the wiring jack 3.

[0034] In a specific embodiment, the cover plate 6 and the connector housing 1 are connected together by a snap connection, wherein one is provided with a snap buckle and the other is correspondingly provided with a snap slot 9 used in conjunction with the snap buckle. Figure 3 and Figure 4 As shown, a buckle is provided on the cover plate 6 , and a slot 9 is provided on the connector housing 1 .

[0035] In another specific embodiment, the cover plate 6 and the connector housing 1 are connected together by threaded connection. Specifically, a connecting through hole is provided at the edge of the cover plate 6, and a screw hole is provided at a position of the connector housing 1 corresponding to the connecting through hole, and the cover plate 6 is connected to the connector housing 1 by screws passing through the connecting through hole.

[0036] In order to connect the connector 11 to the partition 10, the connector housing 1 is provided with a mounting hole 5, and the connector housing 1 is connected to the partition 10 through the mounting hole 5. Specifically, as Figure 3 As shown, the connector 11 is installed on the partition 10 between the instrument room and the circuit breaker room of the switch cabinet through four installation holes 5. Among them, the installation holes 5 are through holes.

[0037] When the connector 11 is mounted on the handcart cabinet, the compatible socket 2 of the lower terminal is used to connect the circuit breaker or other secondary lead plugs to achieve wiring. The terminal 4 of the upper terminal is in the instrument room of the cabinet and is used to connect with secondary components such as control switches and signal lights.

[0038] The connector for the trolley cabinet of the present invention changes the original wiring and connection mode in the cabinet, eliminates the aviation socket, corrugated hose, wire elbow, connecting wire harness, wiring terminal and mounting bracket in the wiring, and realizes the connection between the secondary lead wire of the trolley and the secondary wire system of the cabinet in an integrated manner, simplifies the secondary wiring and wiring in the cabinet, improves production efficiency, reduces the difficulty of inspection and maintenance, and reduces costs.
