DETAILED DESCRIPTION
[0029] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0030] like Figure 1-9As shown, an electrical connector 100 in an embodiment of the utility model includes a fixing assembly 10, a first electrode sheet 20 and a second electrode sheet 30. The fixing assembly 10 includes a connecting plate 11 and a crimping plate 12. The connecting plate 11 is used to be fixed to the PCB board 40. One end of the crimping plate 12 is pivotally connected to the connecting plate 11, and the other end of the crimping plate 12 is detachably fixed to the connecting plate 11. One end of the first electrode sheet 20 and the second electrode sheet 30 are respectively connected to different poles of two adjacent battery packs (for example, the first electrode sheet 20 is connected to the positive pole of one of the battery packs, and the second electrode sheet 30 is connected to the negative pole of the other battery pack), and the other end extends between the crimping plate 12 and the connecting plate 11 and is pressed and fixed.
[0031] According to the connector 100 provided by the utility model, one end of the crimping plate 12 can pivot around the connecting plate 11, and the other end can be fixed to the connecting plate 11, so that the crimping plate 12 can fit tightly with the connecting plate 11 to firmly fix the two electrode sheets on the PCB board 40, thereby realizing a stable connection of the battery pack. When the battery needs to be replaced, first release the fixation between the connecting plate 11 and the other end of the crimping plate 12, then rotate the crimping plate 12 away from the PCB board 40 to loosen the first electrode sheet 20 and the second electrode sheet 30, and then release the connection between the first electrode sheet 20 and the second electrode sheet 30 and the battery pack so that the battery pack can be replaced. After the battery pack is replaced, the corresponding electrode sheets are connected and the crimping plate 12 is rotated and fixed to the PCB board 40. The entire operation process is relatively simple, and the battery pack can be replaced.
[0032] In one embodiment, U-shaped pieces 111 are formed on both sides of the rotating end of the connecting plate 11, and a rotating space is formed between the U-shaped piece 111 and the PCB board 40. Correspondingly, a rotating shaft 121 is provided at the rotating end of the crimping plate 12, and the rotating shaft 121 is limited in the rotating space between the U-shaped piece 111 and the PCB board 40 to realize the pivoting of the crimping plate 12.
[0033] It is conceivable that other pivotal connection modes can be selected between the connecting plate 11 and the crimping plate 12, for example, Figure 8 In the embodiment shown in , the connecting plate 11 is formed with two oppositely arranged insertion holes 115 at one end, and the rotating shaft 221 is inserted into the insertion holes 115 to realize rotation. Different from the U-shaped member 111, the insertion holes 115 completely restrict the crimping plate 12 on the connecting plate 11, and the connecting plate 11 does not contact the PCB board 40, which has higher stability.
[0034] At the same time, the other end of the connecting plate 11 and the crimping plate 12 is a fixed end, and a first fixing hole 112 and a second fixing hole 122 are respectively opened at the fixed end. When the two are fitted together, the two fixing holes are coaxial, and the connecting plate 11 and the crimping plate 12 can be fixed by a fixing bolt 13.
[0035] Similarly, in addition to bolt fixing, the crimping plate 12 and the connecting plate 11 can also be fixed by other means. Fig. 9 In the embodiment shown, a fourth protrusion 116 is provided on the connecting plate, and a matching buckle 125 is provided on the crimping plate 12. After the crimping plate 12 is covered on the connecting plate 11, the fourth protrusion 116 is embedded in the buckle 125, so that the crimping plate 12 is fixed to the connecting plate 11. This fixing method is relatively more flexible, and the crimping plate 12 can be opened or closed without the aid of tools.
[0036] This embodiment provides two pivoting modes and two fixing modes. In actual use, the specific pivoting and fixing modes can be selected according to the actual situation. Of course, in other embodiments, different pivoting and fixing modes can also be selected, and this embodiment does not limit it.
[0037] In order to increase the friction between the electrode sheet and the connecting plate 11 and the crimping plate 12 and prevent the electrode sheet from sliding, a plurality of first protrusions 113 are formed on the surface of the connecting plate 11 that contacts the electrode sheet, so that the contact surface is relatively rough and the friction is relatively large. It is easy to imagine that a plurality of second protrusions 124 are also formed on the surface of the crimping plate 12 that contacts the electrode sheet, so that the contact surface is relatively rough and the friction is increased.
[0038] It can be imagined that the connecting plate 11 and the crimping plate 12 are respectively formed with a protruding portion at the fixed end, and the first fixing hole 112 and the second fixing hole 122 are formed on the protruding portion, which can avoid occupying the middle part for fixing the electrode sheet and at the same time reduce the area of the middle fixed part to reduce costs.
[0039] like Figure 7 As shown, a stopper 123 is provided on the crimping plate 12, which can abut against the PCB board 40, and is used to limit the rotation range of the crimping plate 12 to prevent it from being damaged due to excessive rotation. Specifically, the stopper 123 is formed at the rotation end of the crimping plate 12, and is inclined in a direction away from the connecting plate 11 (the opening direction of the crimping plate 12). When the crimping plate 12 is opened and rotated to a certain angle, the stopper 123 abuts against the PCB board 40. It is easy to imagine that the length and inclination angle of the stopper 123 can be set according to actual conditions to determine the rotation range of the crimping plate 12, and this embodiment does not limit it.
[0040] Of course, it is also possible to choose not to set the above-mentioned block 123 on the crimping half 12, so that the crimping plate 12 can continue to rotate until it abuts against the PCB board 40 or the battery pack, thereby having a larger opening and being more convenient for staff to operate.
[0041] In this embodiment, the first electrode sheet 20 and the second electrode sheet 30 are made of aluminum and copper respectively.
[0042] In order to cooperate with the installation and fixation of the electrical connector 100, corresponding settings need to be made on the PCB board 40 to fix the connecting plate 11. Preferably, a third fixing hole 11 can be opened on the PCB board 40, which is coaxial with the first fixing hole 112 and the second fixing hole 122, and the fixing bolt 13 can extend into the third fixing hole 11 to fix the connecting plate 11 and the crimping plate 12 to the PCB board 40, further improving the fixing effect.
[0043] like Figure 3 , 4 As shown in FIG. 5 , a plurality of fourth fixing holes 42 are provided on the PCB board 40 , and a plurality of third protrusions 114 are correspondingly provided on the connecting plate 11 , which are selectively inserted into the fourth fixing holes 42 to prevent the connecting plate 11 from moving on the surface of the PCB board 40 .
[0044] It is easy to imagine that, since the connecting plate 11 will not be detached from the PCB board 40 under normal circumstances, the third protrusion 114 can be bent after being inserted into the fourth fixing hole 42, or a rubber sleeve can be provided to fix the connecting plate 11 on the PCB board 40.
[0045] like Figure 4 As shown, it is necessary to open a first channel 43 and a second channel 44 on the PCB board 40, and the shapes thereof are the same as those of the first electrode sheet 20 and the second electrode sheet 30 for them to pass through. Preferably, the first channel 43 and the second channel 44 correspond to the electrode positions of adjacent battery packs, so as to avoid bending of the first electrode sheet 20 and the second electrode sheet 30, which would affect the use.
[0046] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
[0047] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
