Description

Technical Field

[0001] The utility model relates to the technical field of electrical wiring, and more specifically to a wiring connector and an energy storage system. Background Art

[0002] In order to ensure the safety of product transportation, the current energy storage system generally needs to disassemble the wire components in the energy storage system before leaving the factory, that is, disassemble the plug and the socket, and then pack the wire components separately for shipment. After arriving at the site and before the whole machine is debugged, the on-site installers will connect the wire components, that is, plug the plug and the socket to achieve conduction of the entire high-voltage circuit.

[0003] On the one hand, although the removal of the wire assembly and separate packaging and delivery ensures the safety of the energy storage system transportation, it will lead to additional packaging and transportation costs; on the other hand, when the on-site installers install the wire assembly, due to the complex high-voltage circuit in the energy storage system, it needs to connect more plugs and sockets, which is easy to cause mis-insertion and wrong insertion. For example, the plug that should be inserted into the third row of sockets is inserted into the second row of sockets; at the same time, the experience and professionalism of the on-site installers vary, and there is not enough time to provide systematic installation training for the installers. Therefore, the installers frequently make wrong insertions and wrong insertions during the actual operation, which in turn causes multiple system short-circuit accidents, causing economic losses and greatly increasing the safety risks of the on-site installers.

[0004] In summary, how to reduce transportation costs and the risk of misoperation such as wrong insertion and misinsertion on site while meeting the safety requirements for transportation of energy storage systems has become a technical problem that needs to be urgently solved by technical personnel in this field.

[0040] The core of the utility model is to provide a wiring connector and an energy storage system, so as to reduce the transportation cost and the risk of mis-insertion or incorrect insertion on site while meeting the safety requirements for transportation of the energy storage system.

[0041] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0042] Reference Figure 1-Figure 12 As shown, the utility model 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 plug-in compatible, and the plug-in compatible 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 compatible position of the plug 1 and the socket 2 in the pre-insertion position.

[0043] In actual application, the wiring connector can be applied to an energy storage system as an example. The socket 2 can be installed at the corresponding position of the electrical equipment 4 of the energy storage system, and the plug 1 can be 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 at 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 then 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 the 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, there is no 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 wrong insertion on site.

[0044] It should be noted that the above-mentioned plug 1 may be provided with a wire connecting part 11 and a first plug-in part 12 connected to the wire connecting part 11, the wire connecting part 11 is mainly used to connect the wiring cable 3, the connection method may be but is not limited to crimping connection, and the wire connecting part 11 and the first plug-in part 12 should be electrically connected, and may be an integrated structure or a split fixed connection structure; the socket 2 is provided with a device connecting part 21 and a second plug-in part 22 connected to the device connecting part 21 and plug-matched with the first plug-in part 12, the device connecting part 21 may be specifically provided with a mounting plate, and is fixedly connected to the corresponding mounting position of the corresponding electrical device 4 through the mounting plate, for example, the mounting plate and the corresponding position of the electrical device 4 are connected by fasteners, and similarly, the device connecting part 21 and the second plug-in part 22 should be electrically connected, and may be an integrated structure or a split fixed connection structure.

[0045] In some specific implementation schemes, the second plug-in 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 plug-in portion 12, the first locking assembly is in an unlocked state, the plug-in operation of the first plug-in portion 12 and the second plug-in portion 22 is not restricted by the first locking assembly, and when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the pre-plug-in position, the first locking assembly can perform a locking action and be adapted and locked with the first locking position 221, and when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the electrical connection plug-in position, the first locking assembly can perform a locking action and be adapted and locked with the second locking position 222. By designing the first locking assembly into the above-mentioned structural form, the plug-in adaptation position between the first plug-in portion 12 and the second plug-in portion 22 can be adapted and locked according to actual needs. Not only the installation and transportation are guaranteed, but also the stability of the on-site electrical connection is guaranteed.

[0046] 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 an embodiment of the utility model. 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.

[0047] In addition, it should be noted that the configuration of the above-mentioned pre-insertion position and the electrical connection insertion position can be that the insertion depth of the first insertion part 12 corresponding to the pre-insertion position into the second insertion part 22 is less than the insertion depth of the first insertion part 12 corresponding to the electrical connection insertion position into the second insertion part 22. In this design form, when the site is adjusted from the pre-installation to the electrical connection state, the operation mode continues to advance the insertion depth of the first insertion part 12 into the second insertion part 22; or the insertion depth of the first insertion part 12 corresponding to the pre-insertion position into the second insertion part 22 is greater than the insertion depth of the first insertion part 12 corresponding to the electrical connection insertion position into the second insertion part 22. In this design form, when the site is adjusted from the pre-installation to the electrical connection state, the operation mode retracts the insertion depth of the first insertion part 12 into the second insertion part 22. In actual application, the arrangement can be selected according to actual needs, and no more specific restrictions are made here.

[0048] In some specific embodiments, reference Figure 1-Figure 9The first locking assembly may specifically include a first lock buckle 121 and a first unlocking member 122 disposed on the first insertion portion 12. The first lock buckle 121 has a locked state and an unlocked state. The first unlocking member 122 is used to drive the first lock buckle 121 to switch between the locked state and the unlocked state, so that the first lock buckle 121 can be adapted to lock with the first locking position 221 or the second locking position 222. By designing the first locking assembly into the above-mentioned structural form, the 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 piece 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 structure of the refill touch button of a ballpoint pen, or the switch button on the power strip, and no further specific limitations are made here.

[0049] 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 the first lock buckle 121 can be driven to switch positions to achieve locking and unlocking by rotating the knob. 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. At this time, if the external force 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.

[0050] 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 indication structure, and when the first lock buckle 121 is in a locked state, the first indication structure points to the first locking mark, and when the first lock buckle 121 is in an unlocked state, the first indication structure points to the first unlocking mark. By designing the first locking mark, the first unlocking mark and the first indication 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 not limited to, a character mark, such as an "on" mark, the first unlocking mark may be, but not limited to, a character mark, such as an "off" mark, and the first indication structure may be, but not limited to, an arrow mark.

[0051] In some specific embodiments, reference Figure 1-Figure 9The first insertion part 12 may be provided with an insertion slot that matches the second insertion part 22. When the first insertion part 12 and the second insertion part 22 are inserted to the electrical connection insertion position, the front end surface of the second insertion part 22 contacts and abuts against the bottom surface of the insertion slot. By designing the structure of the insertion slot, when the first insertion part 12 and the second insertion part 22 are inserted to the electrical connection insertion position, the front end surface of the second insertion part 22 contacts and abuts against the bottom surface of the insertion slot, forming a good limiting effect, avoiding over-positioning of the insertion operation, and effectively reducing the risk of misoperation.

[0052] In some other specific embodiments, referring to Figure 5-Figure 9 The first plug-in portion 12 may also be provided with a second locking component 126 with locking and unlocking functions. When the second locking component 126 is in the unlocked state, the plug-in operation of the first plug-in portion 12 and the second plug-in portion 22 is not restricted by the second locking component 126, and when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the pre-plug-in position, the second locking component 126 can perform a locking action and abut against the front end surface of the second plug-in portion 22. By designing the second locking component 126, when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the pre-plug-in position, a double locking effect can be achieved, 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 lock, and at the same time, the second locking component 126 performs a locking action and abuts against the front end surface of the second insertion part 22, thereby limiting the possibility of the first insertion part 12 and the second insertion part 22 continuing 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.

[0053] In a further embodiment, referring to Figure 7-Figure 9 The second plug-in portion 22 may also be provided with a third locking position 223, and when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the electrical connection plug-in 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, when the first plug-in portion 12 and the second plug-in portion 22 are plugged into the electrical connection plug-in position, a double locking effect can be achieved, and the unlocking caused by the misoperation of the on-site operator can also be avoided.

[0054] In a further embodiment, referring to Figure 7-Figure 9The second locking assembly 126 may include a second lock buckle 1261 and a second unlocking member 1262 disposed on the first plug-in portion 12. The second lock buckle 1261 has a locked state and an unlocked state. The second unlocking member 1262 is used to drive the second lock buckle 1261 to switch between the locked state and the unlocked state, so that the second lock buckle 1261 can abut against the front end surface of the second plug-in portion 22 or be adapted to lock 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. Among them, 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 part 12 to the second insertion part 22, and the second lock buckle 1261 can be configured as a fork disposed at the far end of the knob structure. When the first insertion part 12 is inserted into the second insertion part 22 to the pre-insertion position, rotating the knob can make the fork switch between the two states of abutting against and disengaging from the front end surface of the second insertion part 22. When the first insertion part 12 is inserted into the second insertion part 22 to the electrical connection insertion position, rotating the knob can make the fork switch between the two states of falling into the third locking position 223 and disengaging from the third locking position 223. Of course, it can be understood that the above-mentioned knob structure is only an example of the structure of the second unlocking member 1262 in the embodiment of the utility model. In actual application, it can also be designed as the button structure similar to the first unlocking member 122. In actual application, the configuration can be selected according to actual needs, and no more specific limitation is made here.

[0055] In a further embodiment, referring to Figure 1 , combined with Figure 5 , Figure 6 , Figure 8 and Fig. 9 As shown, the outer side of the first insertion part 12 may also be provided with a second locking mark 123 and a second unlocking mark 124, and the outer side of the second unlocking member 1262 is provided with a second indication structure 125. When the second lock buckle 1261 is in the locked state, the second indication structure 125 points to the second locking mark 123, and when the second lock buckle 1261 is in the unlocked state, the second indication structure 125 points to the second unlocking mark 124. By designing the second locking mark 123, the second unlocking mark 124 and the second indication structure 125, it is more convenient for the second unlocking member 1262 to position the second lock buckle 1261 when performing locking and unlocking operations.

[0056] In some specific embodiments, reference Figure 1-Figure 9The second plug-in part 22 may specifically include a plug-in sleeve 22a and a plug-in pin 22b located at the center of the plug-in sleeve 22a. The first locking position 221 and the second locking position 222 are both arranged on the outer wall of the plug-in sleeve 22a. The first plug-in part 12 may specifically include a first slot 12b adapted to the plug-in pin 22b and a second slot 12a adapted to the plug-in sleeve 22a. By designing the above structural form, the plug-in cooperation between the first plug-in part 12 and the second plug-in part 22 can realize a double plug-in structure, that is, the plug-in pin 22b is plug-in adapted to the first slot 12b, and the plug-in sleeve 22a is plug-in adapted to the second slot 12a, and the plug-in structure is more stable and reliable.

[0057] It should be noted that, refer to Figure 1-Figure 9 The first locking position 221 and the second locking position 222 can be specifically but not limited to an annular groove formed on the outer wall of the insertion sleeve 22a, and of course the third locking position 223 can also be designed as an annular groove structure. By designing the structure in the form of an annular groove, when the first insertion part 12 and the second insertion part 22 are inserted and matched, 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 locking.

[0058] In addition, it should be noted that Fig.10 As shown, 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 specifically limited here; in addition, refer to Fig.11 As shown, the device connection part 21 may be, but is not limited to, designed with wiring terminals, which are electrically connected to the electrical device 4 through the wiring terminals. The device connection part 21 may also be designed with a mounting plate that is mechanically fixed to the corresponding position of the electrical device 4 through fasteners.

[0059] In addition, refer to Figure 10-12 As shown, the utility model also provides an energy storage system, including an electrical device and a wiring cable connected to the electrical device, wherein the wiring cable 3 and the electrical device 4 can be connected via a wiring connector described in any of the above schemes. Since the aforementioned wiring connector has the aforementioned technical effects, the energy storage system having the wiring connector should also have the corresponding technical effects, which will not be described in detail here.

[0060] Specifically, taking the high-voltage circuit of the energy storage system as an example, the combination of the plug and the socket makes the high-voltage circuit of the energy storage system 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 the wire components. After arriving at the customer's site, the entire system circuit is electrically connected through simple operations. 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 accidental insertion at the customer's site can be avoided.
