For the installation between the multiple electric cores 2 and the circuit board 3, each electric core 2 can be independently and detachably electrically connected with the circuit board 3, or the multiple electric cores 2 can be connected in series or in parallel to form an electric core group, and then the electric core group is detachably and electrically connected with the circuit board 3. The connection of the plurality of battery cells 2 is known to those skilled in the art, and in order to facilitate understanding of the following, the following will be described by taking the installation of one battery cell 2 and the circuit board 3 as an example.

In this embodiment, the types of electric devices are various, and common electric devices include an electric tool, an illumination tool, an electric toy, and the like, and in order to facilitate understanding, an electric tool, such as an electric drill, an electric saw, and the like, will be described below as an example. As shown in fig. 1 and 2, a battery compartment 100 that can be opened and closed is provided in a housing 1 of the electric tool, and a circuit board 3 and a battery cell 2 can be mounted in the battery compartment 100. In order to ensure the working stability of the electric tool, the battery compartment 100 may be disposed at a weak position of the electric tool, and then after the battery cell 2 is mounted, the overall mass distribution of the electric tool satisfies the stability requirement. In a specific example, as shown in fig. 1, the battery compartment 100 may be disposed in a handle portion at the rear of the housing 1, so that the battery cell 2 may be mounted in the battery compartment 100 to enable the overall center of gravity of the electric tool to be moved backward, and then the port of the battery compartment 100 is closed by the sealing cover 11, so that the battery cell 2 is stably mounted in the battery compartment 100 by abutting the sealing cover 11 with the outside of the battery cell 2.

It will be appreciated that the battery compartment 100 is disposed within the housing 1 so as not to affect the volume of the power tool when the installation of the battery cell 2 is completed, i.e., the installation of the battery cell 2 does not affect the operation of the power tool. In addition, the installation position of the battery cell 2 is designed according to the overall mass distribution of the electric tool, so that the use stability of the electric tool can be effectively improved.

In this embodiment, as shown in fig. 2 and 3, the circuit board 3 may be mounted to the battery compartment 100 by a fastener, or may be mounted to the battery compartment 100 by a fastening method. The working circuit of the electric equipment is arranged on the circuit board 3, and the battery cell 2 can be directly electrically connected with the working circuit of the electric equipment after being arranged on the circuit board 3, so that the current output stability of the battery cell 2 can be ensured, and the energy loss can be effectively reduced. Meanwhile, a protection circuit is further arranged on the circuit board 3, and the protection circuit can prevent the battery cell 2 from overshooting, overdischarging, short circuit and the like. The protection circuit can be used for multiple times, and the protection circuit can be connected with the working circuit of the electric equipment through the cable, so that the state detection and the protection function of the battery cell 2 are realized.

It should be noted that there are various detachable electrical connection manners between the battery cell 2 and the circuit board 3, such as clamping, plugging, elastic abutment, etc. For easy understanding, the electrical core 2 and the circuit board 3 are preferably connected in a plugging manner in the detachable manner. The specific plugging manner between the battery cell 2 and the circuit board 3 is various, and for convenience of understanding, the following description will be made by using two specific embodiments, and of course, the specific plugging manner between the battery cell 2 and the circuit board 3 includes, but is not limited to, the following two embodiments.

Embodiment one:

As shown in fig. 2 and 3, a first plugging slot 310 is disposed on the circuit board 3, and the battery core 2 is integrally plugged in the first plugging slot 310, so that the positive and negative electrodes of the battery core 2 are electrically connected with the circuit board 3 through two ends of the first plugging slot 310.

It can be understood that the two ends of the first socket 310 are respectively electrically connected with the positive and negative electrodes of the circuit on the circuit board 3, so that when the battery cell 2 is integrally plugged into the first socket 310, the two ends of the battery cell 2 are electrically connected with the two ends of the first socket 310 to realize the electrical connection with the circuit board 3.

In this embodiment, the specific forming manner of the first jack groove 310 may be that the circuit board 3 itself forms the first jack groove 310 by means of concave or convex manner, or that the circuit board 3 is mounted with a corresponding power connection component, and the required first jack groove 310 is formed by the power connection component. Since the electrodes connected to both ends of the first socket 310 are different, a specific formation manner of the first socket 310 is preferably a manner of forming the power receiving assembly in order to conveniently achieve the above-mentioned functions. As a specific example, as shown in fig. 2 and 3, the circuit board 3 is provided with a first electrical connection component for electrical connection in a protruding manner, and the first socket 310 is formed in the first electrical connection component.

In particular, the specific structure of the first socket 310 formed by the first electrical connection assembly may be various, and for convenience of understanding, the following description will be given by way of two specific examples, and of course, the specific structure of the first socket 310 includes, but is not limited to, the following two examples.

As shown in fig. 2 and 3, the circuit board 3 is plate-shaped, and the first electrical connection assembly comprises a pair of first electrical connectors 31 arranged at intervals, wherein the first electrical connectors 31 are perpendicular to the circuit board 3 in a sheet shape, so that the two first electrical connectors 31 are matched to form a first inserting slot 310. Thus, when the battery cell 2 is mounted, the positive and negative electrodes of the battery cell 2 can be electrically connected with the circuit board 3 through the corresponding first electrical connectors 31.

In the second example, the circuit board 3 is plate-shaped, and the first electrical connection assembly includes a pair of first electrical connectors 31 and an insulating sleeve, which are arranged at intervals, and the first electrical connectors 31 and the insulating sleeve can be integrally injection molded. The first electrical connector 31 is in a sheet shape and perpendicular to the circuit board 3, so that when the first electrical connector assembly is mounted on the circuit board 3, a rectangular first inserting groove 310 can be formed between the first electrical connector 31 and the insulating sleeve, and the width of the first inserting groove 310 is matched with the width of the battery cell 2. Thus, when the battery cell 2 is mounted, the positive and negative electrodes of the battery cell 2 can be electrically connected with the circuit board 3 through the corresponding first electrical connectors 31.

It will be appreciated that both of the above examples may meet the needs of the present embodiment. The first socket 310 formed in example two may limit the cell 2 in the width direction compared to the first socket 310 formed in example one. However, the sealing cover 11 for sealing the opening of the battery compartment 100 can limit the battery cell 2 in the width direction, so in order to reduce the production cost and the processing difficulty, the specific structure of the first plugging slot 310 in this embodiment is preferably the first example. Meanwhile, only two first electric connectors 31 are arranged, so that the influence of the first electric connection components on the circuit of the circuit board 3 can be reduced.

It should be appreciated that the specific structure of the first electrical connector 31 is well known to those skilled in the art, and generally, the first electrical connector 31 is a conductive metal member, such as an elastic metal sheet, etc., and an anti-oxidation coating may be further applied to the first electrical connector 31 in order to ensure the service life of the first electrical connector 31. The first electrical connector 31 is typically mounted to the circuit board 3 by soldering.

It should be further understood that the structures of the two first electrical connectors 31 may be identical or non-identical, and that the first mating grooves 310 need only be formed for the non-identical first electrical connectors 31.

Embodiment two:

Compared with the first embodiment, the second embodiment is different in that, as shown in fig. 4 to 8, a first electric connection component is electrically connected to the circuit board 3, a second electric connection component is electrically connected to the battery core 2, and the anode and the cathode of the battery core 2 are electrically connected to the circuit board 3 through the plugging of the second electric connection component and the first electric connection component.

It can be appreciated that the second electrical connection assembly is mounted on the electrical core 2 to achieve the plugging with the first electrical connection assembly, so that the abrasion generated when the electrical core 2 is directly plugged with the first plugging slot 310 through the electrode in the first embodiment can be effectively reduced. The first electrical connection component is formed with the first insertion groove 310 in the first embodiment, so that the battery cell 2 is inserted into the first insertion groove 310 through the second electrical connection component, and the second electrical connection component is inserted into the second electrical connection component through a plurality of insertion grooves. The second plugging means is more structurally stable than the first plugging means, so that the second plugging means is preferably used in the present embodiment. There are various specific implementations of the second plugging manner, and for convenience of understanding, the following description will be given by way of specific three examples.

As shown in fig. 2, 4, 6 and 8, the first electrical connection assembly includes at least one pair of electrical connectors, the second electrical connection assembly is provided with a second plugging slot 410 at the positive and negative electrodes of the electrical core 2, and the positive and negative electrodes of the electrical core 2 are electrically connected to the circuit board 3 through plugging of the electrical connectors with the corresponding plugging slots.

It should be noted that, among the electrical connectors included in the first electrical connection assembly, two electrical connectors are used to connect the positive and negative poles of the working circuit of the electrical equipment, and may be defined as the first electrical connector 31. The second plugging slot 410 only needs to plug with the two first electrical connectors 31 to electrically connect the battery cell 2 with the circuit board 3. If other electric connectors are also present in the first electric connection assembly, the first electric connection assembly can be plugged with plugging grooves arranged at other positions on the second electric connection assembly so as to improve the installation stability of the battery cell 2.

The second example is that at least one pair of inserting grooves are arranged on the first electric connection assembly, the second electric connection assembly comprises two electric connection pieces arranged on the positive electrode and the negative electrode of the battery cell 2, and the positive electrode and the negative electrode of the battery cell 2 are electrically connected to the circuit board 3 through the insertion of the electric connection pieces and the corresponding inserting grooves.

It should be noted that, among the slots included in the first electrical connection assembly, two slots are used to connect the positive and negative poles of the working circuit of the electrical device, and may be defined as the second slot 410. The electrical connection between the battery core 2 and the circuit board 3 can be achieved by simply plugging two electrical connectors into two second plugging grooves 410. If the first electric connection component is also provided with other plugging grooves, the first electric connection component can be plugged with electric connection pieces arranged at other positions on the second electric connection component so as to improve the installation stability of the battery cell 2.

The third example is that at least one plugging slot and at least one electric connector are arranged on the first electric connection component, the electric connector and the plugging slot are respectively arranged on the anode and the cathode of the electric core 2 of the second electric connection component, and the anode and the cathode of the electric core 2 are electrically connected with the circuit board 3 through the plugging of the electric connector and the corresponding plugging slot.

It should be noted that the first electrical connection assembly includes a socket and an electrical connector, where one socket and one electrical connector are respectively connected to the positive and negative poles of the working circuit of the electrical device. The electric connecting piece and the inserting groove which are arranged on the positive electrode and the negative electrode of the electric core 2 on the second electric connecting component are respectively inserted with the inserting groove and the electric connecting piece on the first electric connecting component to realize the electric connection between the electric core 2 and the circuit board 3. The first electric connection assembly further comprises other plugging grooves and electric connectors, and the first electric connection assembly can be plugged with the electric connectors and the plugging grooves arranged at other positions on the second electric connection assembly to improve the installation stability of the battery cell 2.

Specifically, for the first example and the second example, which are substantially the same, taking the first example as an example, as shown in fig. 4 to 6, the second electrical connection assembly includes two second electrical connectors 41 respectively disposed on the positive and negative electrodes of the battery cell 2, and the second plugging slot 410 is disposed on the second electrical connectors 41. The two second electrical connectors 41 may be identical or non-identical in structure, and the non-identical second electrical connectors 41 are only required to be capable of being plugged with the first electrical connectors 31. For example three, the second electrical connection assembly includes second electrical connectors 41 respectively disposed at the positive and negative electrodes of the battery cell 2, and the first electrical connection assembly includes a pair of first electrical connectors 31 corresponding to the second electrical connectors 41. A second socket 410 is provided on each of the first electrical connector 31 and the second electrical connector 41. I.e. the two first electrical connectors 31 are not identical in structure, nor are the two second electrical connectors 41 identical in structure. In a specific example, one of the first electrical connectors 31 and one of the second electrical connectors 41 are identical in structure and are in the shape of a sheet, and the other one of the first electrical connectors 31 and one of the second electrical connectors 41 are identical in structure and are provided with the second plugging grooves 410.

It will be appreciated that the above three examples can meet the needs of the present embodiment, and the design of example three is slightly more complex than that of example one and example two, so that the above-mentioned example one and example two are preferably adopted for the second plugging manner in the present embodiment, and the example one and example two are substantially the same, so that the following description will take example one as an example.

In this embodiment, the specific structure of the second plugging slot 410 is various, and for convenience of understanding, the following description will be made by using one specific structure. As shown in fig. 4 and 5, the second electrical connector 41 includes a mating portion 412, two sides of the mating portion 412 are provided with curled sections 4121 curled toward the center, and the curled sections 4121 cooperate with non-curled areas of the mating portion 412 to form the second mating groove 410.

It is understood that the width X of the second mating groove 410 may be the distance from the end of the crimped segment 4121 to the non-crimped region on the mating portion 412. The value of the width X is slightly smaller than the thickness of the first electrical connector 31, so that when the second plugging slot 410 is plugged with the first electrical connector 31, the electrical connection stability of the first electrical connector 31 and the second electrical connector 41 can be ensured through the elastic deformation of the curled section 4121. That is, the crimping section 4121 is capable of forming the second mating groove 410 and simultaneously compressing the second electrical connector 41 to the first electrical connector 31 by elastic deformation.

It should be noted that, for the formation of the second mating groove 410, the two ends of the mating portion 412 may be crimped by stamping to obtain the corresponding second mating groove 410.

In this embodiment, the contact area between the second electrical connector 41 and the electrode of the battery core 2 is 20% -80% of the whole electrode area.

It should be noted that in order to ensure the power supply stability between the battery cell 2 and the circuit board 3, a sufficient contact area is required between the second electrical connector 41 and the electrode of the battery cell 2. Typically, the electrode contact area of the second electrical connector 41 with the cell 2 is at least 20% of the total electrode area. Considering the connection between the second electrical connector 41 and the electrode of the battery cell 2, if the second electrical connector 41 is welded to the battery cell 2, a certain welding space needs to be reserved between the second electrical connector 41 and the electrode of the battery cell 2, so that the contact area between the second electrical connector 41 and the electrode of the battery cell 2 cannot be greater than 80% of the whole electrode area. More preferably, the contact area between the power receiving portion 411 and the electrode of the battery cell 2 is 30% -70% of the whole electrode area.

In the present embodiment, the second electrical connector 41 is connected to the battery cell 2 in a plurality of ways, including but not limited to the following two specific ways.

In the first connection mode, as shown in fig. 4 and 6, the second electrical connector 41 is welded to the electrode of the battery cell 2, and then the second electrical connection assembly is mounted on the battery cell 2.

In the second connection mode, as shown in fig. 7 and 8, the second electrical connection assembly further includes an insulating member 42, and the two second electrical connection members 41 are connected through the insulating member 42, so that an electrical connection cavity is formed between the two second electrical connection members 41. The second electric connection component is clamped with the anode and the cathode of the battery cell 2 through the electric connection cavity so as to be arranged on the battery cell 2.

It will be appreciated that for the second connection mode described above, the second electrical connection assembly may be formed by integral injection molding between the insulating member 42 and the two second electrical connection members 41. The two second electrical connectors 41 are structurally connected to each other by an insulating member 42, but are not electrically connected to each other, so that a short circuit between the two second electrical connectors 41 is avoided.

It is further understood that, for the first connection mode, if the second electrical connector 41 is directly soldered to the electrode of the battery cell 2 through the plugging portion 412, the structure of the second plugging slot 410 formed by the plugging portion 412 may be affected, and thus the plugging of the second plugging slot 410 with the first electrical connector 31 may be difficult. For the second connection mode, if the second electrical connector 41 is directly mated with the plugging portion 412 to form the electrical cavity, the height of the plugging portion 412 is long, and it is necessary to simultaneously satisfy the integrally formed connection of the insulating member 42, and also to satisfy the requirement of abutting and clamping the electrodes of the battery cell 2, and the processing of the long plugging portion 412 is difficult.

In this embodiment, in order to facilitate the connection between the second electrical connector 41 and the electrical core 2, as shown in fig. 4 to 8, the second electrical connector 41 further includes an electrical connection portion 411, where the electrical connection portion 411 is integrally connected with the plug portion 412 or connected by welding, and the second electrical connector 41 may be connected with the electrode of the electrical core 2 through the electrical connection portion 411, that is, the second electrical connector 41 may be welded or abutted with the electrode of the electrical core 2 through the electrical connection portion 411.

It can be understood that the second electrical connector 41 is a conductive metal piece, such as a nickel sheet, and if the power receiving portion 411 and the plugging portion 412 are integrally connected, the required second electrical connector 41 can be obtained by punching and bending the metal sheet with a T-shaped structure at two side extending positions. For the split connection of the power connection part 411 and the plug part 412, the second electrical connector 41 is obtained by simply connecting the power connection part 411 and the plug part 412, which are separately processed, by soldering.

The foregoing has outlined the basic principles, features, and advantages of the present application. It will be understood by those skilled in the art that the present application is not limited to the embodiments described above, and that the above embodiments and descriptions are merely illustrative of the principles of the present application, and various changes and modifications may be made therein without departing from the spirit and scope of the application, which is defined by the appended claims. The scope of the application is defined by the appended claims and equivalents thereof.
