Description

Technical Field

[0001] The present application relates to the field of electric power technology, and in particular to a connection device and an electrical device. Background Art

[0002] The connector is used to connect at least two electrical devices to enable power transmission between the two electrical devices. However, the existing connector cannot carry large currents, making the connector not universal. Utility Model Content

[0003] The main technical problem solved by the present application is to provide a connection device and an electrical device to solve the problem that the existing connector cannot carry large current for connection.

[0004] In order to solve the above technical problems, the first technical solution adopted by the present application is: to provide a connection device, which includes a shell, a plurality of conductors and two insulating clamps. The plurality of conductors are inserted into the shell; the first ends of the plurality of conductors extend out of the shell and form a plurality of first transition parts arranged at intervals, and the second ends of the plurality of conductors extend out of the shell and form a plurality of second transition parts arranged at intervals. The two insulating clamps are connected to the shell; the plurality of first transition parts are arranged between the two insulating clamps; the plurality of first transition parts cooperate with the two insulating clamps to form a plurality of clamping grooves. The conductor is an integrally formed conductive plate.

[0005] In this way, by using two insulating clamps, multiple conductors can be clamped between the two insulating clamps, so that multiple first connectors of the first electrical device are clamped in multiple clamping grooves. Thus, multiple first connectors of the first electronic device are connected to multiple second connectors of the second electronic device through multiple conductors of the connecting device (i.e., the first adapter, the conductor part located in the shell, and the second adapter). The first adapter of the conductor can connect multiple first connectors, and the second adapter of the conductor can connect multiple second connectors; so that the connecting device can meet the adapter function of most brands. Multiple conductors are installed in the shell, so that the multiple conductors and the shell form a whole, which is convenient for transportation. The conductor is an integrally formed conductive plate (i.e., the first adapter, the conductor part located in the shell, and the second adapter are integrally formed), so that the current carrying capacity of the conductor is large (the conductor can withstand a large current without damage), thereby solving the problem that the existing connector cannot carry a large current, and making the connecting device universal.

[0006] In some embodiments, the plurality of conductors are all bent copper bars. Alternatively, the plurality of conductors include a plurality of bent copper bars and a flat copper bar. In this way, the portion of the conductor inside the housing is relatively compact, thereby reducing the size of the housing and the weight of the housing.

[0007] In some embodiments, the end of the insulating clamping member away from the housing extends beyond the end of the first adapter away from the housing. Thus, when a plurality of first connectors of a first electrical device are inserted into the clamping groove from the end of the first adapter away from the housing, the insulating clamping member can limit the insertion distance of the first connectors in the clamping groove to avoid collision with the second insulating layer, or even knocking off the second insulating layer.

[0008] In some embodiments, the insulating clamp includes a first clamping plate and a second clamping plate. The first clamping plate is connected to the shell. The second clamping plate is connected to the shell and is located on the side of the first clamping plate away from the first adapter. Among them, the end of the second clamping plate away from the shell exceeds the end of the first adapter away from the shell, and the end of the first adapter away from the shell exceeds the end of the first clamping plate away from the shell. In this way, a clamping groove can be formed between the first clamping plate of the first insulating clamp and a first adapter, and the weight of the first clamping plate can also be reduced. When multiple first connectors of a first electrical device are inserted into the clamping groove from the end of the first adapter away from the shell, the second clamping plate can limit the insertion distance of the first connector to avoid colliding with the second insulating layer and falling off.

[0009] In some embodiments, the connection device further includes an insulating connector, which passes through each first clamping plate, each second clamping plate, and a plurality of first transition portions. In this way, the insulating connector passes through two insulating clamping members and a plurality of first transition portions to play a positioning role. The insulating connector can be used to force the two insulating clamping members to move closer to or away from each other, and tighten or loosen the plurality of first transition portions. When the first connector is to be inserted into the clamping groove, the insulating connector can be used to clamp the first connector in the clamping groove, thereby reducing the problem of loosening or shaking of the first connector in the clamping groove, etc., which may cause poor contact.

[0010] In some embodiments, the insulating connector includes a bolt and a nut. In this way, the bolt passes through the first insulating clamp, the plurality of first transition portions, and the second insulating clamp in sequence, and is threadedly connected to the bolt by the nut, so as to adjust the distance between the two insulating clamps.

[0011] In some embodiments, the connecting device further comprises a first elastic member and / or a second elastic member, wherein the first elastic member is disposed on a side of one insulating clamping member away from the first adapter portion. The second elastic member is disposed on a side of another insulating clamping member away from the first adapter portion. In this way, the first elastic member and the second elastic member can reduce the problem of the nut becoming loose due to mechanical vibration or the like.

[0012] In some embodiments, the first adapter has a first surface and a second surface facing each other; the first surface is entirely covered by the first insulating layer; the portion of the second surface close to the housing is covered by the second insulating layer, and the portion away from the housing is exposed. In this way, the first connector can be inserted into the clamping groove from the end of the first adapter away from the housing, so that the first connector is in contact with and connected to the exposed portion of the second surface of the first adapter, connecting the first connector to the connecting device. The second insulating layer serves to limit the insertion extent of the first connector to prevent the first connector from contacting the housing; and also serves to prevent the first connector from moving toward one side of the housing.

[0013] In some embodiments, one end of the first clamping plate away from the housing extends beyond one end of the second insulating layer away from the housing. Thus, the first clamping plate of the first insulating clamp and the exposed portion of the second surface of the first transition portion form a clamping groove.

[0014] In some embodiments, the second insulating layer is detachably disposed on the second surface. In this way, the thickness of the second insulating layer can be selected according to the thickness of the first connector, so that the first connector is clamped by two adjacent first connectors, or by one first connector and the first insulating clamp. This allows the connecting device to meet the needs of first connectors of different thicknesses, and has strong versatility.

[0015] In order to solve the above technical problems, the second technical solution provided by the present application is: to provide an electrical device. The electrical device includes a first electrical device, a second electrical device and the above connection device; the first connection member of the first electrical device is located in the clamping groove and is electrically connected to the first adapter; the second connection member of the second electrical device is electrically connected to the second adapter. Since the electrical device includes the above connection device, the electrical device has the same effect as the above connection device.

[0016] In some embodiments, the thickness of the second insulating layer is equal to the thickness of the first connector. Thus, when the first connector is located in the clamping member, the second insulating layer of one first transition portion contacts the first insulating layer of an adjacent first transition portion.

DETAILED DESCRIPTION

[0023] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0024] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0027] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0028] In the related art, for example, two electrical devices are connected by the cooperation of the conductive parts of the connector; the conductive parts of the connector are connected by welding or splicing. However, the structures of the conductive parts are different (for example, the conductive part can be a rod, a plate or a block, etc.), so that the maximum current that the connector can withstand is the same as the maximum current of the conductive part with the smallest current among the maximum currents of the multiple conductive parts (for example, the maximum current of the rod, the plate and the block has the smallest current, and the maximum current of the rod is the maximum current of the connector at this time, while the maximum current of the plate and the block is greater than the maximum current of the rod), so that the one conductive part limits the scope of use of the connector. As a result, the connector cannot carry large currents, making the connector not universal.

[0029] The embodiment of the present application provides an electrical device. Figure 1The electrical device includes a first electrical device 1, a second electrical device 3 and a connecting device 2; the first connecting member 11 of the first electrical device 1 is located in the clamping groove and is electrically connected to the first adapter 221; the second connecting member 31 of the second electrical device 3 is electrically connected to the second adapter 224. In this way, the first electrical device 1 and the second electrical device 3 are electrically connected through the connecting device 2.

[0030] The first electrical device 1 can be connected to equipment such as a generator, a transformer, a distribution box, a distribution cabinet, and a cable. The second electrical device 3 can be connected to equipment such as a generator, a transformer, a distribution box, a distribution cabinet, and a cable. The first electrical device 1 and the second electrical device 3 can be the same or different, for example, both are transformers. The first connecting member 11 can be a plate, in which case it can be called a first connecting plate; the first connecting member 11 can also be a wire, in which case it can be called a first connecting wire (such as a cable). The second connecting member 31 can be a plate, in which case it can be called a second connecting plate. The second connecting member 31 can also be a wire, in which case it can be called a second connecting wire (such as a cable).

[0031] See also Figure 2 to Figure 4 The connection device 2 may include a housing 23, two insulating clamps 21 and a plurality of conductors 22. The plurality of conductors 22 are inserted into the housing 23; the first ends of the plurality of conductors 22 extend out of the housing 23 and form a plurality of first transition portions 221 arranged at intervals, and the second ends of the plurality of conductors 22 extend out of the housing 23 and form a plurality of second transition portions 224 arranged at intervals. The two insulating clamps 21 are connected to the housing 23; the plurality of first transition portions 221 are arranged between the two insulating clamps 21; the plurality of first transition portions 221 cooperate with the two insulating clamps 21 to form a plurality of clamping grooves. The conductor 22 is an integrally formed conductive plate.

[0032] By using two insulating clamps 21, multiple conductors 22 can be clamped between the two insulating clamps 21, so that the multiple first connectors 11 of the first electrical device 1 are clamped in multiple clamping grooves. Thereby, the multiple first connectors 11 of the first electronic device are connected to the multiple second connectors 31 of the second electronic device through the multiple conductors 22 of the connecting device 2 (i.e., the first adapter 221, the conductor part located in the shell 23, and the second adapter 224). The first adapter 221 of the conductor 22 can connect the multiple first connectors 11, and the second adapter 224 of the conductor 22 can connect the multiple second connectors 31; so that the connecting device 2 can meet the adapter function of most brands. The multiple conductors 22 are installed in the shell 23, so that the multiple conductors 22 and the shell 23 form a whole, which is convenient for transportation. The conductor 22 is an integrally formed conductive plate (i.e., the first adapter part 221, the conductor part located in the shell 23, and the second adapter part 224 are integrally formed), so that the current carrying capacity of the conductor 22 is large (the conductor 22 can withstand a large current without being damaged), thereby solving the connection problem that the existing connector cannot carry a large current, and making the connecting device 2 universal.

[0033] The material of the shell 23 may be an insulating material, which may be a non-metallic material, such as hard plastic, resin, etc. The material of the shell 23 may also be a conductive material, but an insulating layer is coated on the outer surface of the shell 23 to prevent the shell 23 from being connected to the conductor 22. The shell 23 may have a receiving cavity, a first opening, and a second opening; the first opening and the second opening are both connected to the receiving cavity. The conductor 22 is installed in the receiving cavity of the shell 23, the first end of the conductor 22 extends out of the shell 23 from the first opening, and the second end of the conductor 22 extends out of the shell 23 from the second opening. Multiple conductors 22 are fixed in the shell 23, for example, there is a card slot in the shell 23, and multiple conductors 22 are carded in the card slot.

[0034] In some examples, the first ends of the plurality of conductors 22 extend out of the housing 23, are first bent outward to form a first fan-out structure, and then form a plurality of first transition portions 221 disposed at intervals. The second ends of the plurality of conductors 22 extend out of the housing 23, are first bent outward to form a second fan-out structure, and then form a plurality of second transition portions 224 disposed at intervals.

[0035] In order to avoid mutual conduction between multiple conductors 22 (for example, multiple conductors 22 located outside the shell 23, and for example, multiple conductors 22 located inside the shell 23), for example, adjacent conductors 22 are arranged separately, and for example, each conductor 22 is coated with an insulating layer. Since multiple first transition parts 221 are arranged at intervals and clamped by two insulating clamps 21, there is an insulating layer between two adjacent first transition parts 221 of the multiple first transition parts 221; for example, the insulating layer can be the first insulating layer and the second insulating layer 26 mentioned below, and for example, the insulating layer can only be the first insulating layer mentioned below. Since multiple second transition parts 224 are arranged at intervals and multiple second transition parts 224 are separated, the second transition part 224 may not be wrapped with an insulating layer. Among them, the materials of the insulating layer, the first insulating layer and the second insulating layer 26 are all insulating materials, for example, the insulating material can be resin (for example, epoxy resin), plastic, etc. For example, the resin is epoxy resin, and both the insulation performance and the heat dissipation performance are good.

[0036] The plurality of first transition portions 221 arranged at intervals can be understood as the plurality of first transition portions 221 being distributed at intervals along the first direction X, and two adjacent first transition portions 221 being insulated from each other (i.e., not conducting). The plurality of second transition portions 224 arranged at intervals can be understood as the plurality of second transition portions 224 being distributed at intervals along the first direction X, and two adjacent second transition portions 224 being insulated from each other (i.e., not conducting). The first direction X intersects (e.g., is perpendicular to) the plate surface of the conductive plate.

[0037] In some examples, the first end and the second end may be arranged opposite to each other, so that the first adapter portion 221 and the second adapter portion 224 are in a straight line. In other examples, the extension lines of the first end and the second end intersect (e.g., are perpendicular), so that the first adapter portion 221 and the second adapter portion 224 are in a cross shape (e.g., a right angle).

[0038] The material of the conductor 22 may be a metal material; the metal material may be a metal element, such as gold, silver, aluminum, copper, etc.; the metal material may also be a metal alloy, such as an alloy of the above metal elements. The material of the conductor 22 may also be a non-metal material, such as graphite, etc.

[0039] The conductor 22 is an integrally formed conductive plate. It can be understood that the portion of the conductor 22 located in the housing 23, the first transition portion 221 and the second transition portion 224 (as well as the first fan-out portion and the second fan-out portion) are formed into a conductive plate through a one-time molding process.

[0040] In some examples, the insulating clamp 21 may be a single-layer structure. In this case, the material of the insulating clamp 21 may be an insulating material, which may be a non-metallic material, such as hard plastic, resin, etc. The material of the insulating clamp 21 may also be a conductive material, but an insulating layer is coated on the outer surface of the insulating clamp 21 to prevent the insulating clamp 21 from being conductive with the conductor 22. In other examples, the insulating clamp 21 may be a multi-layer structure. For example, the insulating clamp 21 may include a first clamping plate 211 and a second clamping plate 212 described below.

[0041] The insulating clamp 21 is connected to the housing 23. For example, the insulating clamp 21 is fixedly connected to the housing 23, or the insulating clamp 21 is detachably connected (for example, connected by bolts 242) to the housing 23. In some examples, the first clamping plate 211 and the second clamping plate 212 mentioned below are both connected to the housing 23.

[0042] Multiple first adapter portions 221 cooperate with two insulating clamping members 21 to form multiple clamping grooves; it can be understood that a clamping groove can be formed between two adjacent first adapter portions 221 of the multiple first adapter portions 221, a first adapter portion 221 of the multiple first adapter portions 221 that is closest to an insulating clamping member 21 (one insulating clamping member 21 can be called a first insulating clamping member 21) and a clamping groove can be formed with the first insulating clamping member 21, and a first adapter portion 221 of the multiple first adapter portions 221 that is closest to another insulating clamping member 21 (the other insulating clamping member 21 can be called a second insulating clamping member 21) and a second insulating clamping member 21 can be in contact (i.e., no clamping groove is formed). In this way, the multiple first connecting members 11 of the first electrical device 1 are clamped in the multiple clamping grooves, so that the first connecting member 11 is in contact and connected with a first adapter portion 221 forming the clamping groove, and an adjacent first adapter portion 221 is insulated (i.e., not conductive); so as to avoid electrical faults caused by two adjacent first adapter portions 221 being conductively connected by the first connecting member 11.

[0043] In some examples, the second adapter 224 may have at least one (e.g., one, or more) connection hole 225, so that one second adapter 224 may be connected to at least one second connector 31. For example, the number of the connection holes 225 is 4, and the 4 connection holes 225 may form an arrangement of 1 row and 4 columns, or 4 rows and 1 column. For example, the number of the connection holes 225 is 8, and the 8 connection holes 225 may form an arrangement of 2 rows and 4 columns, or 4 rows and 2 columns.

[0044] In some examples, for example, one or more first connectors 11 of a first electrical device 1 can be connected to a first adapter 221 of a conductor 22. For another example, multiple first connectors 11 of a first electrical device 1 can be connected to the first adapter 221 of multiple conductors 22. For example, one or more second connectors 31 of a second electrical device 3 can be connected to a second adapter 224 of a conductor 22. For another example, multiple second connectors 31 of a second electrical device 3 can be connected to the second adapter 224 of multiple conductors 22. Herein, multiple first connectors 11 of a first electrical device 1 are connected to the first adapter 221 of multiple conductors 22, and multiple second connectors 31 of second electrical devices 3 are connected to the second adapter 224 of a conductor 22. For example, the description is made by taking the example that multiple first connectors 11 of a first electrical device 1 are connected to the first adapter 221 of multiple conductors 22, and multiple second connectors 31 of second electrical devices 3 are connected to the second adapter 224 of a conductor 22.

[0045] The number of the plurality of (e.g., two, three, four, five, six, etc.) conductors 22 is the same as the number of the plurality of clamping slots. For example, the number of the plurality of conductors 22 may be five, so that the connection device 2 may form five clamping slots, and the five clamping slots may be a PE clamping slot, a C clamping slot, a B clamping slot, an A clamping slot, and an N clamping slot.

[0046] In some embodiments, the plurality of conductors 22 are all bent copper bars. Or the plurality of conductors 22 include a plurality of bent copper bars and a flat copper bar. In this case, the copper bar can be understood as the material of the above-mentioned conductive plate being copper or copper alloy. In this way, the portion of the conductor 22 in the housing 23 is relatively compact, thereby reducing the size of the housing 23 and reducing the weight of the housing 23. Bending can be understood as the portion of the plurality of conductors 22 being bent outward to form the above-mentioned first fan-out portion and the second fan-out portion.

[0047] The plurality of conductors 22 include a plurality of bent copper bars and a flat copper bar; it can be understood that when the number of the plurality of conductors 22 is an odd number, one of the plurality of conductors 22 is a flat copper bar, and the remaining conductors 22 are bent copper bars; and the remaining conductors 22 are symmetrically arranged with respect to the one conductor 22. The plurality of conductors 22 are all bent copper bars; it can be understood that when the number of the plurality of conductors 22 is an even number, the plurality of conductors 22 are all bent copper bars, and the plurality of conductors 22 are symmetrically arranged.

[0048] In the case where the conductor 22 is a bent copper bar, the conductor 22 located between the first transition portion 221 and the second transition portion 224 may include a straight segment 222, a first bent segment 226, and a second bent segment 223. At least a portion of the straight segment 222 is located within the housing 23. The first bent segment 226 and the second bent segment 223 are respectively connected to both ends of the straight segment 222, and the first bent segment 226 and the second bent segment 223 are both bent outward to form the above-mentioned first fan-out portion and the second fan-out portion, respectively.

[0049] In some embodiments, the end of the insulating clamp 21 away from the housing 23 exceeds the end of the first adapter 221 away from the housing 23. In this way, when a plurality of first connectors 11 of a first electrical device 1 are inserted into the clamping groove from the end of the first adapter 221 away from the housing 23, the insulating clamp 21 can limit the insertion distance of the first connector 11 in the clamping groove to avoid collision with the second insulating layer 26, or even knock off the second insulating layer 26.

[0050] In some examples, when the insulating clamp 21 is a multi-layer structure, the end of the insulating clamp 21 away from the housing 23 exceeds the end of the first adapter 221 away from the housing 23, which can be understood as that the ends of all structures of the insulating clamp 21 away from the housing 23 are all beyond the end of the first adapter 221 away from the housing 23. In other examples, when the insulating clamp 21 is a multi-layer structure, the end of the insulating clamp 21 away from the housing 23 exceeds the end of the first adapter 221 away from the housing 23, which can also be understood as that the ends of some structures of the insulating clamp 21 away from the housing 23 exceed the end of the first adapter 221 away from the housing 23, and the ends of other structures away from the housing 23 do not exceed the end of the first adapter 221 away from the housing 23. For example, the insulating clamp 21 may include a first clamping plate 211 and a second clamping plate 212.

[0051] In some embodiments, the insulating clamping member 21 may include a first clamping plate 211 and a second clamping plate 212. The first clamping plate 211 is connected to the housing 23. The second clamping plate 212 is connected to the housing 23, and the second clamping plate 212 is located on a side of the first clamping plate 211 away from the first adapter 221. The end of the second clamping plate 212 away from the housing 23 exceeds the end of the first adapter 221 away from the housing 23, and the end of the first adapter 221 away from the housing 23 exceeds the end of the first clamping plate 211 away from the housing 23. In this way, a clamping groove can be formed between the first clamping plate 211 of the first insulating clamping member 21 and a first adapter 221, and the weight of the first clamping plate 211 can also be reduced. When a plurality of first connectors 11 of a first electrical device 1 are inserted into the clamping groove from the end of the first adapter 221 away from the housing 23, the second clamping plate 212 can limit the insertion distance of the first connector 11 to avoid collision with the second insulating layer 26 and falling off.

[0052] In some examples, the material of the first clamping plate 211 may be an insulating material, which may be a non-metallic material, such as hard plastic, resin, etc. The material of the first clamping plate 211 may be a conductive material, but an insulating layer is coated on the outer surface of the first clamping plate 211. The material of the second clamping plate 212 may be an insulating material or a conductive material. Among them, the materials of the first clamping plate 211 and the second clamping plate 212 may be insulating materials.

[0053] In some embodiments, the connecting device 2 further includes an insulating connector 24. The insulating connector 24 passes through each first clamping plate 211, each second clamping plate 212, and a plurality of first transition portions 221. In this way, the insulating connector 24 passes through two insulating clamping members 21 and a plurality of first transition portions 221 to play a positioning role. The insulating connector 24 can be used to force the two insulating clamping members 21 to move closer to or away from each other, and tighten or loosen the plurality of first transition portions 221. When the first connector 11 is to be inserted into the clamping groove, the insulating connector 24 can be used to clamp the first connector 11 in the clamping groove, thereby reducing the problem of loosening or shaking of the first connector 11 in the clamping groove, etc., which may cause poor contact.

[0054] In some embodiments, the insulating connector 24 may include a slide rod and a clamp, the slide rod sequentially passes through the first insulating clamp 21, multiple first transition portions 221 and the second insulating clamp 21, and the clamp is clamped on the slide rod to adjust the distance between the two insulating clamps 21.

[0055] In some embodiments, the insulating connector 24 includes a bolt 242 and a nut 241. In this way, the bolt 242 passes through the first insulating clamp 21, the first transition portions 221 and the second insulating clamp 21 in sequence, and the nut 241 is threadedly connected to the bolt 242 to facilitate adjusting the distance between the two insulating clamps 21.

[0056] In some embodiments, the connection device 2 further includes a first elastic member 25, which is disposed on a side of one insulating clamping member 21 away from the first adapter 221. And / or, the connection device 2 further includes a second elastic member 27, which is disposed on a side of another insulating clamping member 21 away from the first adapter 221. In this way, the first elastic member 25 and the second elastic member 27 can reduce the problem of the nut 241 becoming loose due to mechanical vibration or the like.

[0057] The first elastic member 25 may be a spring, an elastic sheet, etc. The second elastic member 27 may be a spring, an elastic sheet, etc. In some examples, the first elastic member 25 and the second elastic member 27 are both elastic sheets.

[0058] Exemplarily, the connection device 2 further includes a first elastic member 25, which is disposed on a side of one insulating clamping member 21 away from the first transition portion 221. Also exemplarily, the connection device 2 further includes a second elastic member 27, which is disposed on a side of another insulating clamping member 21 away from the first transition portion 221. Also exemplarily, the connection device 2 further includes a first elastic member 25 and a second elastic member 27. The first elastic member 25 is disposed on a side of one insulating clamping member 21 away from the first transition portion 221; the second elastic member 27 is disposed on a side of another insulating clamping member 21 away from the first transition portion 221.

[0059] In some embodiments, the first adapter 221 has a first surface and a second surface facing each other; the first surface is completely covered by the first insulating layer; the portion of the second surface close to the housing 23 is covered by the second insulating layer 26, and the portion away from the housing 23 is exposed. In this way, the first connector 11 can be inserted into the clamping groove from the end of the first adapter 221 away from the housing 23, so that the first connector 11 is in contact with the exposed portion of the second surface of the first adapter 221, and the first connector 11 is connected to the connecting device 2. The second insulating layer 26 serves to limit the insertion degree of the first connector 11 to prevent the first connector 11 from contacting the housing 23; it also serves to prevent the first connector 11 from moving toward one side of the housing 23.

[0060] The exposed portion of the second surface of one of the first transition parts 221 of the plurality of conductors 22 forms a clamping groove with the first insulating clamp 21. A clamping groove is formed between the exposed portion of the second surface of one of the two adjacent first transition parts 221 and the first insulating layer of the other first transition part 221. Both the first surface and the second surface intersect (e.g., are perpendicular to) the first direction X.

[0061] In some embodiments, one end of the first clamping plate 211 away from the housing 23 exceeds one end of the second insulating layer 26 away from the housing 23. Thus, the first clamping plate 211 of the first insulating clamp 21 and the exposed portion of the second surface of the first transition portion 221 form a clamping groove.

[0062] In some embodiments, the second insulating layer 26 is detachably disposed on the second surface. In this way, the thickness of the second insulating layer 26 can be selected according to the thickness of the first connector 11, so that the first connector 11 is clamped by two adjacent first connectors, or by one first connector and the first insulating clamp 21. The connecting device 2 can meet the needs of first connectors 11 of different thicknesses, and has strong versatility.

[0063] In some examples, the thickness of the second insulating layer 26 is equal to the thickness of the first connector 11. In this way, when the first connector 11 is located in the clamp, the second insulating layer 26 of one first transition portion 221 contacts the first insulating layer of an adjacent first transition portion 221. In other examples, the thickness of the first connector 11 is greater than the thickness of the second insulating layer 26.

[0064] In some examples, the second insulating layer 26 is disposed on the second surface in a removable manner, for example, the second insulating layer 26 is adhered to the second surface by gluing.

Any equivalent structure or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
