Description

Wiring connector and energy storage system

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on January 31, 2024, with application number 202420246533.7 and application name “A Wiring Connector and Energy Storage System”, the entire contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of electrical wiring technology, and more specifically, to a wiring connector and an energy storage system. Background Art

[0003] To ensure safe transportation of energy storage systems, the wire assemblies in the system must be separated before shipment. This means the plugs and sockets are separated, and the wire assemblies are then packaged and shipped separately. Upon arrival at the site, and before the entire system is debugged, on-site installers will connect the wire assemblies, plugging the plugs and sockets together to ensure continuity of the entire high-voltage circuit.

[0004] On the one hand, while removing the conductor assembly and packaging it separately for shipment ensures the safe transportation of the energy storage system, it incurs additional packaging and transportation costs. On the other hand, when on-site installers install the conductor assembly, the complex high-voltage circuits in the energy storage system require numerous plugs and sockets to connect, making it easy for them to mis-insert or mis-insert the components. For example, a plug that should have been inserted into the third row of sockets was inserted into the second row. Furthermore, the experience and expertise of on-site installers vary widely, and there's insufficient time for systematic installation training. Consequently, mis-insertion and mis-insertion are frequent, leading to numerous system short-circuit incidents, resulting in economic losses and significantly increased safety risks for on-site installers.

[0005] In summary, how to reduce transportation costs and the risk of misoperation such as on-site misplugging and incorrect plugging while meeting the safety requirements for energy storage system transportation has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present application provides a wiring connector and an energy storage system to reduce transportation costs and the risk of mis-insertion or incorrect insertion on site while meeting the safety requirements for transportation of the energy storage system.

[0012] In some embodiments of the present application, a first locking mark and a first unlocking mark are provided on the outside of the first plug-in portion, and a first indication structure is provided on the outside of the first unlocking member. When the first lock buckle is in a locked state, the first indication structure points to the first locking mark, and when the first lock buckle is in an unlocked state, the first indication structure points to the first unlocking mark.

[0013] In some embodiments of the present application, an insertion slot compatible with the second insertion slot is provided on the first insertion portion. When the first insertion portion and the second insertion portion are inserted into the electrical connection insertion position, the front end surface of the second insertion portion contacts and abuts against the bottom surface of the insertion slot.

[0014] In some embodiments of the present application, a second locking assembly with locking and unlocking functions is further provided on the first plug-in part. When the second locking assembly is in the unlocked state, the plug-in operation of the first plug-in part and the second plug-in part is not restricted by the second locking assembly, and when the first plug-in part and the second plug-in part are plugged into the pre-plug-in position, the second locking assembly can perform a locking action and abut against the front end face of the second plug-in part.

[0016] In some embodiments of the present application, the second locking assembly includes a second lock buckle and a second unlocking member arranged on the first plug-in part, the second lock buckle has a locked state and an unlocked state, and the second unlocking member is used to drive the second lock buckle to switch between the locked state and the unlocked state, so that the second lock buckle can be abutted against the front end face of the second plug-in part or adapted to lock in the third locking position.

[0017] In some embodiments of the present application, a second locking mark and a second unlocking mark are provided on the outside of the first plug-in portion, and a second indication structure is provided on the outside of the second unlocking member. When the second lock buckle is in a locked state, the second indication structure points to the second locking mark, and when the second lock buckle is in an unlocked state, the second indication structure points to the second unlocking mark.

The plug and socket can be pre-installed when the entire energy storage system is shipped. Specifically, the plug is first inserted into the pre-insertion position of the socket, and the plug-in and socket plug-in position is locked in the pre-insertion position by the first locking assembly. Since the plug and socket are locked in the pre-insertion position, the energy storage system can be safely transported. After being transported to the target site, the first locking assembly is adjusted to the unlocked state, and then the plug-in and socket plug-in position is adjusted to the electrical connection position, completing the electrical connection between the plug and socket. Compared with the traditional on-site wiring operation method, with this wiring connector, the electrical connection operation of the energy storage system is performed after it is transported to the target site, avoiding problems such as poor contact or false connection caused by bumps in the electrical connection during transportation of the energy storage system, ensuring the safety requirements of the energy storage system transportation, and the pre-installation of the wire assembly has been completed at the factory, and there is no need to disassemble the wire assembly for transportation, which reduces transportation costs.

DETAILED DESCRIPTION

[0038] The present application provides a wiring connector and an energy storage system to reduce transportation costs and the risk of mis-insertion or incorrect insertion on site while meeting the safety requirements for transportation of the energy storage system.

[0039] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0040] Referring to Figures 1 to 12, the present application provides a wiring connector, including a plug 1, a socket 2 and a first locking assembly, wherein the plug 1 and the socket 2 are plugged in and adapted, and the plug-in adaptation positions of the two include a pre-insertion position and an electrical connection plug-in position, and the first locking assembly has locking and unlocking functions and is at least used to lock the plug-in adaptation position of the plug 1 and the socket 2 in the pre-insertion position.

[0041] In actual application, taking the application to the energy storage system as an example, the socket 2 can be installed to the corresponding position of the electrical equipment 4 of the energy storage system, and the plug 1 is connected to the corresponding wiring cable 3. The plug 1 and the socket 2 can be pre-installed when the entire energy storage system leaves the factory. Specifically, the plug 1 is first inserted into the pre-insertion position of the socket 2, and the plug-in adaptation position of the plug 1 and the socket 2 is locked in the pre-insertion position through the first locking component. Since the plug 1 and the socket 2 are locked in the pre-insertion position, the energy storage system can be safely transported. After being transported to the target site, the first locking component is adjusted to the unlocked state, and then the plug-in adaptation position of the plug 1 and the socket 2 is adjusted to the electrical connection plug-in position, and the electrical connection between the plug 1 and the socket 2 is completed. Compared with the traditional on-site wiring operation method, with this wiring connector, the electrical connection operation of the energy storage system is performed after it is transported to the target site, avoiding problems such as poor contact or false connection caused by bumps in the electrical connection during transportation of the energy storage system, ensuring the safety requirements of the energy storage system transportation, and the pre-installation of the wire assembly has been completed at the factory, without the need to disassemble the wire assembly for transportation, reducing transportation costs, and during the electrical connection process after transportation to the site, there is no need to match the plug 1 and the socket 2 one by one. It is only necessary to continue to adjust the first locking assembly on the basis of pre-installation and adjust the plug-in adaptation position of the plug 1 and the socket 2. The operation is very simple and convenient, which greatly reduces the risk of misoperation such as wrong insertion and incorrect insertion on site.

[0042] It should be noted that the above-mentioned plug 1 can be provided with a wire connection part 11 and a first plug-in part 12 connected to the wire connection part 11. The wire connection part 11 is mainly used to connect the wiring cable 3. The connection method can be but is not limited to crimping connection, and the wire connection part 11 and the first plug-in part 12 should be electrically connected, which can be an integrated structure or a split fixed connection structure; the socket 2 is provided with a device connection part 21 and a second plug-in part 22 connected to the device connection part 21 and plugged into the first plug-in part 12. The device connection part 21 can be specifically provided with a mounting plate, which is fixedly connected to the corresponding mounting position of the corresponding electrical equipment 4 through the mounting plate, for example, the mounting plate and the corresponding position of the electrical equipment 4 are connected by fasteners. Similarly, the device connection part 21 and the second plug-in part 22 should be electrically connected, and can be an integrated structure or a split fixed connection structure.

[0043] In some specific embodiments, the second insertion portion 22 may be provided with a first locking position 221 and a second locking position 222. The first locking assembly is provided on the first insertion portion 12. When the first locking assembly is in an unlocked state, the insertion operation of the first insertion portion 12 and the second insertion portion 22 is not restricted by the first locking assembly. When the first insertion portion 12 and the second insertion portion 22 are inserted into the pre-insertion position, the first locking assembly can perform a locking action and adaptively lock with the first locking position 221. When the first insertion portion 12 and the second insertion portion 22 are inserted into the electrical connection insertion position, the first locking assembly can perform a locking action and adaptively lock with the second locking position 222. By designing the first locking assembly into the above-mentioned structural form, the insertion adaptation position between the first insertion portion 12 and the second insertion portion 22 can be adaptively locked according to actual needs. This not only ensures installation and transportation, but also ensures the stability of the on-site electrical connection.

[0044] It should be noted that the above-mentioned design of the first locking component on the first plug-in part 12 is only a preferred example of the embodiment of the present application. In actual application, it can also be designed on the second plug-in part 22, and the corresponding first plug-in part 12 is designed with a first locking position and a second locking position, that is, the corresponding structures of the plug 1 and the socket 2 are interchangeable.

[0045] In addition, it should be noted that the configuration of the above-mentioned pre-insertion position and the electrical connection insertion position can be such that the insertion depth of the first insertion portion 12 corresponding to the pre-insertion position into the second insertion portion 22 is less than the insertion depth of the first insertion portion 12 corresponding to the electrical connection insertion position into the second insertion portion 22. In this design form, when adjusting from the pre-installation state to the electrical connection state on site, the operation mode continues to advance the insertion depth of the first insertion portion 12 into the second insertion portion 22. Alternatively, the insertion depth of the first insertion portion 12 corresponding to the pre-insertion position into the second insertion portion 22 is greater than the insertion depth of the first insertion portion 12 corresponding to the electrical connection insertion position into the second insertion portion 22. In this design form, when adjusting from the pre-installation state to the electrical connection state on site, the operation mode retracts the insertion depth of the first insertion portion 12 into the second insertion portion 22. In actual application, the arrangement can be selected according to actual needs, and no further specific limitation is made here.

[0046] In some specific embodiments, referring to Figures 1-9, the first locking assembly may include a first lock catch 121 and a first unlocking member 122 disposed on the first insertion portion 12. The first lock catch 121 has a locked state and an unlocked state. The first unlocking member 122 is used to drive the first lock catch 121 to switch between the locked state and the unlocked state, so that the first lock catch 121 can be locked with the first locking position 221 or the second locking position 222. By designing the first locking assembly into the above-mentioned structural form, locking and unlocking operations are more convenient. Among them, the first locking position 221 and the second locking position 222 can be specifically designed as card slots arranged in sequence along the insertion direction, the first lock buckle 121 can be specifically designed as a card pin that can be extended into and out of the card slot, and the first unlocking member 122 can be specifically configured as a button. Touching the button once can drive the card pin to extend into the card slot to achieve locking, and touching the button twice can drive the card pin to exit the card slot to achieve unlocking. The driving structure of the button touching the card pin can be similar to the refill touch button of a ballpoint pen, or the structure of the switch button on the power strip, and no further specific limitation is made here.

[0047] Of course, it is understandable that in actual application, the driving structure of the first lock buckle 121 and the first unlocking member 122 can also be designed into other structural forms. For example, the first unlocking member 122 can be configured as a knob structure, and by rotating the knob, the first lock buckle 121 can be driven to switch positions to achieve locking and unlocking. In addition, the above-mentioned first locking assembly can also be designed into a structural form without the first unlocking member 122. For example, the first lock buckle 121 can also be designed into a structural form such as an elastic tongue or an elastic bead. In this case, if the external force of the insertion of the first insertion part 12 and the second insertion part 22 removes the disengagement force of the elastic tongue or the elastic bead, the first lock buckle 121 can be disengaged from the slot. The advantage of this structural form is that the structure is simpler, but the stability is weaker.

[0048] In a further implementation scheme, the outside of the first plug-in portion 12 may also be provided with a first locking mark and a first unlocking mark, and the outside of the first unlocking member 122 may be provided with a first indicating structure. When the first lock buckle 121 is in the locked state, the first indicating structure points to the first locking mark, and when the first lock buckle 121 is in the unlocked state, the first indicating structure points to the first unlocking mark. By designing the above-mentioned first locking mark, first unlocking mark and first indicating structure, it is more convenient and accurate for the first unlocking member 122 to control the first lock buckle 121 to perform locking and unlocking operations. For example, when the first unlocking member 122 is configured as a knob structure, the first locking mark may be, but is not limited to, a character mark, such as an "on" mark, the first unlocking mark may be, but is not limited to, a character mark, such as an "off" mark, and the first indicating structure may be, but is not limited to, an arrow mark.

[0049] In some specific embodiments, referring to Figures 1-9, the first insertion portion 12 may be provided with an insertion slot adapted to mate with the second insertion portion 22. When the first insertion portion 12 and the second insertion portion 22 are inserted into the electrical connection insertion position, the front end surface of the second insertion portion 22 contacts and abuts against the bottom surface of the insertion slot. By designing the structure of the insertion slot, when the first insertion portion 12 and the second insertion portion 22 are inserted into the electrical connection insertion position, the front end surface of the second insertion portion 22 contacts and abuts against the bottom surface of the insertion slot, forming a good limit position, preventing over-positioning during insertion and effectively reducing the risk of misoperation.

[0050] In other specific embodiments, referring to Figures 5 to 9, the first insertion portion 12 may also be provided with a second locking assembly 126 having locking and unlocking functions. When the second locking assembly 126 is in the unlocked state, the insertion operation of the first insertion portion 12 and the second insertion portion 22 is not restricted by the second locking assembly 126. When the first insertion portion 12 and the second insertion portion 22 are inserted into the pre-insertion position, the second locking assembly 126 can perform a locking action and abut against the front end surface of the second insertion portion 22. By designing the second locking assembly 126, a double locking effect can be achieved when the first insertion portion 12 and the second insertion portion 22 are inserted into the pre-insertion position, further reducing the risk of misoperation by on-site operators. For example, when the insertion depth of the first insertion part 12 and the second insertion part 22 corresponding to the pre-insertion position is less than the insertion depth of the first insertion part 12 and the second insertion part 22 corresponding to the electrical connection insertion position, when the first insertion part 12 and the second insertion part 22 are inserted into the pre-insertion position, the first lock buckle 121 and the first locking position 221 are adapted to be locked, and at the same time, the second locking component 126 performs a locking action and abuts against the front end face of the second insertion part 22, limiting the possibility of the first insertion part 12 and the second insertion part 22 to continue to advance the insertion operation, and at this time the first lock buckle 121 can be designed as an elastic tongue or an elastic bead structure.

[0051] In a further embodiment, referring to Figures 7-9, the second insertion portion 22 may be further provided with a third locking position 223, and when the first insertion portion 12 and the second insertion portion 22 are inserted into the electrical connection insertion position, the second locking assembly 126 can perform a locking action and lock with the third locking position 223. By designing the third locking position, a double locking effect can be achieved when the first insertion portion 12 and the second insertion portion 22 are inserted into the electrical connection insertion position, and the situation of unlocking caused by the operator's misoperation can also be avoided.

[0052] In a further embodiment, referring to Figures 7-9, the second locking assembly 126 may include a second lock catch 1261 and a second unlocking member 1262 disposed on the first insertion portion 12. The second lock catch 1261 has a locked state and an unlocked state. The second unlocking member 1262 is used to drive the second lock catch 1261 to switch between the locked state and the unlocked state, so that the second lock catch 1261 can abut against the front end surface of the second insertion portion 22 or be locked with the third locking position 223. By designing the second locking assembly 126 into the above-mentioned structural form, the locking and unlocking operations are more convenient. The second unlocking member 1262 can be designed as a knob structure, and the rotation center of the knob structure is parallel to the insertion center of the first insertion portion 12 into the second insertion portion 22. The second lock buckle 1261 can be configured as a shift fork provided at the distal end of the knob structure. When the first insertion portion 12 is inserted into the second insertion portion 22 to the pre-insertion position, rotating the knob can cause the shift fork to switch between abutting against and disengaging from the front end surface of the second insertion portion 22. When the first insertion portion 12 is inserted into the second insertion portion 22 to the electrical connection insertion position, rotating the knob can cause the shift fork to switch between being in the third locking position 223 and being disengaged from the third locking position 223. It is understood that the above-mentioned knob structure is merely an example of the structure of the second unlocking member 1262 in the embodiment of the present application. In actual application, it can also be designed as a button structure similar to the above-mentioned first unlocking member 122. In actual application, the configuration can be selected according to actual needs, and no further specific limitation is given here.

[0053] In a further embodiment, referring to FIG1 , in combination with FIG5 , FIG6 , FIG8 and FIG9 , a second locking mark 123 and a second unlocking mark 124 may be further provided on the outside of the first insertion portion 12, and a second indicating structure 125 may be provided on the outside of the second unlocking member 1262. When the second lock buckle 1261 is in the locked state, the second indicating structure 125 points to the second locking mark 123, and when the second lock buckle 1261 is in the unlocked state, the second indicating structure 125 points to the second unlocking mark 124. The design of the second locking mark 123, the second unlocking mark 124 and the second indicating structure 125 makes it easier to locate the second unlocking member 1262 when performing locking and unlocking operations on the second lock buckle 1261.

[0054] In some specific embodiments, referring to Figures 1-9, the second insertion portion 22 can include an insertion sleeve 22a and a pin 22b located at the center of the insertion sleeve 22a. The first locking position 221 and the second locking position 222 are both located on the outer wall of the insertion sleeve 22a. The first insertion portion 12 can include a first slot 12b that is compatible with the pin 22b and a second slot 12a that is compatible with the insertion sleeve 22a. This design allows the first insertion portion 12 and the second insertion portion 22 to achieve a dual insertion structure, with the pin 22b inserting and fitting into the first slot 12b and the sleeve 22a inserting and fitting into the second slot 12a, making the insertion structure more stable and reliable.

[0055] It should be noted that, referring to Figures 1-9, the first locking position 221 and the second locking position 222 can be specifically, but not limited to, configured as an annular groove formed on the outer wall of the insertion sleeve 22a. Of course, the third locking position 223 can also be designed as an annular groove structure. By designing the structure as an annular groove, when the first insertion portion 12 and the second insertion portion 22 are inserted and mated, even if the two rotate relative to each other, the position change of the first locking position 221 and the second locking position 222 will not be affected, thereby ensuring the effectiveness of the locking.

[0056] It should also be noted that, as shown in Figure 10, the wire connection portion 11 on the plug 1 can be electrically connected to the wiring cable 3 by crimping, or other connection methods commonly used by those skilled in the art, which are not further specifically limited here; in addition, as shown in Figure 11, the device connection portion 21 can be designed with, but not limited to, a wiring terminal, which is electrically connected to the electrical device 4 by means of a wiring terminal, and the device connection portion 21 can also be designed with a mounting plate that is mechanically fixed to the corresponding position of the electrical device 4 by fasteners.

[0057] Furthermore, referring to Figures 10-12 , the present application further provides an energy storage system comprising an electrical device and a wiring cable connected to the electrical device. The wiring cable 3 and the electrical device 4 can be connected via a wiring connector as described in any of the above-described embodiments. Since the aforementioned wiring connectors have the aforementioned technical effects, an energy storage system incorporating such wiring connectors should also have corresponding technical effects, which will not be further elaborated here.

[0058] Specifically, taking the high-voltage circuit of the energy storage system as an example, the combination of plugs and sockets enables the high-voltage circuit of the energy storage system to be in two connection states according to actual needs. In the pre-installation state (that is, only mechanically connected), the entire system circuit is in a disconnected state, which can achieve safe transportation of the energy storage system and avoid the additional cost of separate packaging and transportation of wire components; after arriving at the customer's site, a simple operation is performed to make the entire system circuit electrically connected. At the same time, since the wire components are already in a pre-installation state when mechanically connected (the on-site process will be checked according to the circuit diagram before leaving the factory), the risk of wrong insertion or incorrect insertion at the customer's site can be avoided.

[0059] Those skilled in the art should understand that the above-mentioned energy storage system generally includes an equipment structure 43, and an electrical device 4 is installed in the equipment cabinet 43.
