Description

Technical Field

[0001] This disclosure relates to an electrical connection assembly for a vehicle's electrical system. This disclosure further relates to a vehicle that includes an electrical system and the electrical connection assembly. Background Technology

[0002] Electrical connection components are used to electrically connect different parts of a vehicle's electrical system. Technological advancements (including current electrification trends) have significantly increased the number of such electrical connection components.

[0003] Electrical connection components typically include a socket and a connector that can be connected to that socket. These types of electrical connection components can provide a quick and easy way to electrically connect different parts of a vehicle's electrical system, for example, during vehicle assembly, maintenance, or repair. However, these electrical connection components also come with some challenges and problems.

[0004] One issue is that, for example, during vehicle assembly, maintenance, or repair, it is crucial to achieve a correct and secure connection between connectors and sockets. Incorrect connections can lead to malfunctions in various parts, components, or subsystems of the vehicle, or at least reduce system performance.

[0005] Furthermore, connectors are prone to disengagement during vehicle operation. Such unexpected disconnections, typically caused by vibration or mechanical stress, can lead to operational malfunctions or at least degrade system performance. The possibility of loosening or complete detachment of contacts poses a threat to vehicle reliability and safety.

[0006] The service life of electrical connection components is also an issue. Electrical connection components may be exposed to various environmental factors (such as dirt, mud, water, and gravel) during vehicle operation, which can cause wear and tear. These factors not only pose a risk of immediate damage but also gradually degrade the connections, thus shortening the component's lifespan. Summary of the Invention

[0007] The object of this invention is to overcome or at least mitigate at least some of the problems and disadvantages described above. This object is achieved through the subject matter of the appended independent claims.

[0008] According to a first aspect of this disclosure, this objective is achieved by an electrical connection assembly for a vehicle's electrical system, wherein the assembly includes one or more receptacle / connector pairs, each receptacle / connector pair including a receptacle and a connector capable of being connected to the receptacle, wherein the connector includes a connector body and a locking member movably disposed relative to the connector body between an unlocked position and a locked position. The locking member is configured to lock the connector to the receptacle when the connector is connected to the receptacle and the locking member is in the locked position. The assembly includes a clamping unit. The clamping unit and the connector are configured such that the clamping unit can only be fitted onto the connector when the locking member is in the locked position.

[0009] Since the clamping unit can only be assembled onto the connector when the locking member is in the locked position, it is ensured that the locking member is in the locked position when the clamping unit is assembled onto the connector. In this way, when an assembler or assembly machine is able to assemble the clamping unit onto the connector (e.g., when assembling, maintaining, or repairing a vehicle including electrical connection components), the assembler or assembly machine can confirm that the locking member is in the locked position. In other words, an electrical connection assembly is provided that ensures that the connector is locked to the socket when the connector is connected to the socket and the clamping unit is assembled onto the connector. Therefore, the risk of poor electrical connection between the connector and the socket is reduced, thereby reducing the risk of operational failures and performance degradation of various parts, components, or subsystems of the vehicle.

[0010] Furthermore, the clamping unit protects the connectors and sockets of the electrical connection components from environmental factors such as dirt, mud, water, and stones. This reduces wear on the connectors and sockets, potentially extending the lifespan of the electrical connection components and lowering the risk of operational failures and performance degradation in the vehicle's electrical system.

[0011] Therefore, an electrical connection assembly is provided that overcomes or at least mitigates some of the aforementioned problems and disadvantages. Thus, the above-mentioned objectives are achieved.

[0012] Optionally, if the locking member is in the unlocked position, the clamping unit is prevented from being fitted onto the connector by an abutment contact between a portion of the clamping unit and the locking member. Thus, an electrical connection assembly is provided in which the clamping unit is prevented from being fitted onto the connector in a simple and effective manner when the locking member is in the unlocked position. Furthermore, a clamping unit with a simple structure can be provided that indicates whether the locking member of the connector is in the locked position when attempting to fit the clamping unit onto the connector.

[0013] Optionally, the clamping unit includes a U-shaped profile formed by a first arm, a second arm, and a connecting section connecting the first arm and the second arm. This provides an electrical connection assembly that is simple and intuitive to use.

[0014] In addition, improved conditions are provided for protecting connectors and sockets of electrical connection components from environmental factors such as dirt, mud, water and stones.

[0015] Optionally, a portion of the clamping unit is located at the distal end of the first arm. This provides a simple clamping unit that can indicate whether the locking member of the connector is in the locked position when attempting to assemble the clamping unit onto the connector.

[0016] Optionally, the locking member is configured to snap into a locked position when the connector is fully inserted into the socket. This provides a simple and intuitive electrical connection assembly. Furthermore, since the clamping unit can only be fitted onto the connector when the locking member is in the locked position, the assembler or assembly machine can verify that the connector is fully inserted into the socket when the clamping unit is fitted onto the connector.

[0017] Alternatively, the locking member is formed by a latch that is flexibly arranged relative to the connector body between the locked position and the unlocked position. This provides a simple yet reliable locking member.

[0018] Optionally, the receptacle includes a recess, and the locking member includes a hole configured to receive the recess when the connector is connected to the receptacle and the locking member is in the locked position. This ensures that the connector is securely held relative to the receptacle in a simple and effective manner when the connector is connected to the receptacle and the locking member is in the locked position.

[0019] Optionally, the notch is configured to move the locking member from a locked position to an unlocked position as the connector moves relative to the receptacle during insertion. This provides a simple and intuitive electrical connection assembly because it eliminates the need for the assembler or assembly machine to move the locking member from the locked position to the unlocked position before or during connector insertion into the receptacle. Furthermore, since the notch is configured to move the locking member from the locked position to the unlocked position as the connector moves relative to the receptacle, the assembler or assembly machine can indicate that the connector is not fully inserted into the receptacle when the clamping unit cannot be fitted onto the connector. Therefore, in this way, for example, during the assembly, maintenance, or repair of a vehicle including the electrical connection assembly, it can be further ensured that the connector is fully inserted into the receptacle.

[0020] Optionally, the clamping unit and locking member are configured such that when the connector is connected to the receptacle and the clamping unit is mounted on the connector, the clamping unit prevents the locking member from moving from the locked position to the unlocked position. Thus, an electrical connection assembly is provided that prevents the connector from unexpectedly disconnecting from the receptacle during operation of a vehicle including the electrical connection assembly. Therefore, an electrical connection assembly is provided that reduces the risk of operational failures and performance degradation of various parts, components, or subsystems of the vehicle. Furthermore, an electrical connection assembly is provided that enhances the vehicle reliability and operational safety of a vehicle including the electrical connection assembly.

[0021] Optionally, the connector includes an actuator movably disposed relative to the connector body between a default position and an unlocked position, wherein the actuator is operatively connected to a locking member such that when the actuator moves from the default position to the unlocked position, the locking member moves from the locked position to the unlocked position, and wherein the clamping unit and the actuator are configured such that when the clamping unit is fitted onto the connector, the clamping unit prevents the actuator from moving from the default position to the unlocked position. Thus, an electrical connection assembly is provided that is simple and intuitive to use, while preventing the connector from unexpectedly disconnecting from the receptacle during operation of a vehicle including the electrical connection assembly. Additionally, the clamping unit protects the connector's actuator from environmental elements such as dirt, mud, water, and stones. This could potentially reduce connector wear and extend the lifespan of electrical connection components.

[0022] Optionally, the connector can be inserted into the socket along the insertion direction, and the clamping unit and the connector are configured such that the clamping unit can be mounted on the connector along an installation direction perpendicular to the insertion direction. Thus, an electrical connection assembly is provided that is simple and intuitive to use, while providing confirmation during assembly regarding whether the locking member of the connector is in the locked position.

[0023] Optionally, the clamping unit and connector are configured such that when the clamping unit is mounted on the connector, the clamping unit applies a clamping force to the connector. This ensures that the clamping unit is securely held relative to the connector in a simple and effective manner. Furthermore, an electrical connection assembly is provided that is simple and intuitive to use, as it avoids or at least reduces the need for further securing of the clamping unit relative to the connector.

[0024] Optionally, the connector can be inserted into the socket along the insertion direction, and the clamping unit includes a series of ridges that prevent the clamping unit from moving in a direction parallel to the insertion direction when it is mounted on the connector. This further ensures that the clamping unit is securely held relative to the connector in a simple and effective manner.

[0025] Optionally, the clamping unit is configured to abut against two opposing portions of the connector when the clamping unit is assembled onto the connector, and a locking member is arranged on one of the two opposing portions. This provides an electrical connection assembly with simple and intuitive operation. Furthermore, an electrical connection assembly is provided that has features to ensure that the locking member remains in a locked position when the clamping unit is assembled onto the connector.

[0026] Optionally, the component includes a receptacle mounting member and two or more receptacle / connector pairs, the two or more receptacle / connector pairs collectively comprising two or more receptacles arranged adjacent to each other on the receptacle mounting member and two or more connectors each capable of connecting to one of the two or more receptacles, wherein the clamping unit and the two or more connectors are configured such that the clamping unit can only be fitted onto the two or more connectors when the locking members of the two or more connectors are in their respective locked positions. This ensures that when the clamping unit is fitted onto two or more connectors, The locking members of two or more connectors are in their respective locked positions. In this way, during the connection process from two or more connectors to two or more sockets (e.g., when assembling, maintaining, or repairing a vehicle including electrical connection components), when the assembler or assembly machine is able to assemble the clamping unit onto two or more connectors, the assembler or assembly machine can confirm that the locking members of the two or more connectors are in their respective locked positions. In other words, an electrical connection assembly is provided that ensures that when two or more connectors are connected to their respective sockets and the clamping unit is assembled onto the two or more connectors, the two or more connectors are locked to their respective sockets.

[0027] According to a second aspect of this disclosure, this objective is achieved by a vehicle comprising an electric system and electrical connection components according to a first aspect of this disclosure.

[0028] Therefore, a vehicle including an electrical connection assembly is provided, which ensures that, for example, during vehicle assembly, maintenance, or repair, the connector of the electrical connection assembly is locked into the corresponding socket. Furthermore, a vehicle including an electrical connection assembly is provided that has enhanced resistance to environmental factors such as dirt, mud, water, and stones. This reduces wear on the connectors and sockets, potentially extending the service life of the vehicle's electrical connection assembly. Additionally, the risk of poor electrical connection between the connector and socket is reduced, thereby lowering the risk of operational failures and performance degradation in the vehicle's electrical system.

[0029] Therefore, a vehicle is provided that overcomes or at least mitigates some of the aforementioned problems and disadvantages. Thus, the aforementioned objective is achieved.

[0030] Optionally, the electrical system is configured to supply power to the vehicle's electric propulsion system. Thus, a vehicle is provided that reduces the risk of operational failures and performance degradation of the vehicle's electric propulsion system caused by poor electrical connections.

[0031] Optionally, the electrical system has a nominal voltage equal to or higher than 60 volts. Thus, a vehicle is provided that has conditions to reduce the risk of operational failures and performance degradation of various parts, components, or subsystems of the vehicle's electrical system having a nominal voltage equal to or higher than 60 volts. Operational failures and performance degradation of such parts, components, or subsystems can lead to more significant adverse effects compared to those of electrical systems with a nominal voltage lower than 60 volts.

[0032] Optionally, the vehicle is a heavy-duty road vehicle, such as a truck or a bus. Thus, a heavy-duty road vehicle having at least some of the advantages described above is provided.

[0033] Further features and advantages of the invention will become apparent when examined in light of the appended claims and the following detailed description. Attached Figure Description

[0035] The various aspects of this disclosure will now be described more fully. Similar reference numerals always refer to similar elements. For the sake of brevity and / or clarity, well-known functions or constructions will not be described in detail.

[0036] Figure 1 Vehicle 2 is schematically illustrated according to some embodiments. According to the illustrated embodiments, vehicle 2 is a truck, i.e., a type of heavy-duty road vehicle and a type of heavy-duty commercial vehicle. According to other embodiments, as mentioned herein, vehicle 2 can be another type of heavy or lighter manned or unmanned vehicle for land-based or water-based propulsion, such as a truck, bus, construction vehicle, tractor, automobile, ship, boat, etc.

[0037] According to the illustrated embodiment, vehicle 2 includes an electric propulsion system 30. The electric propulsion system 30 is configured to power vehicle 2 via wheels 27. The electric propulsion system 30 may include one or more motors operatively connected to one or more wheels 27 of vehicle 2.

[0038] According to the illustrated embodiment, the electric propulsion system 30 is configured to power the vehicle 2 via the rear wheels 27. The vehicle 2 also includes steerable, non-drive front wheels 27'. According to another embodiment, the electric propulsion system 30 may be configured to power the vehicle 2 via the front wheels 27'.

[0039] According to the illustrated embodiment, vehicle 2 is a pure electric vehicle, which includes an electric propulsion system 30 as the sole power source for vehicle 2 and does not include an internal combustion engine. However, according to another embodiment, vehicle 2 may be a so-called hybrid electric vehicle, which includes an internal combustion engine in addition to the electric propulsion system 30 for powering vehicle 2. Furthermore, according to some embodiments of this disclosure, vehicle 2 may include an internal combustion engine as the sole power source for vehicle 2.

[0040] Vehicle 2 includes an energy storage system 18 configured to store electrical energy. Electric propulsion system 30 is configured to operate using electricity from the energy storage system 18. The energy storage system 18 may include multiple battery packs, each including multiple rechargeable battery cells, such as lithium-ion battery cells, lithium polymer battery cells, lithium iron phosphate (LFP) battery cells, etc. Alternatively or additionally, vehicle 2 may include... A pressure tank, such as a cryogenic pressure tank, is configured to store hydrogen. According to such embodiments, vehicle 2 may include one or more fuel cells configured to generate electricity through a chemical reaction between oxygen and hydrogen from the pressure tank. The electric propulsion system 30 of vehicle 2 may be configured to operate using electricity from such one or more fuel cells.

[0041] exist Figure 1 The diagram indicates the electric system 20 of vehicle 2. According to the illustrated embodiment, the electric system 20 of vehicle 2 is configured to transmit power between the electric energy storage system 18 and the electric propulsion system 30 of vehicle 2.

[0042] According to the illustrated implementation scheme, the power system 20 is a high-voltage power system with a nominal voltage within the so-called voltage level B (commonly abbreviated as VCB), that is, a nominal voltage equal to or higher than 60 volts. Therefore, the power system 20 of vehicle 2 can also be referred to as a VCB power system or a high-voltage power system.

[0043] According to another implementation scheme, as mentioned herein, the electrical system 20 of vehicle 2 may be a low-voltage electrical system having a nominal voltage within the so-called voltage level A (usually abbreviated as VCA), i.e., a nominal voltage of less than 60 volts.

[0044] Furthermore, according to some implementation schemes, as mentioned herein, the electrical system 20 of vehicle 2 may have a nominal voltage equal to or greater than 60 volts, but may be configured to supply power to one or more other types of systems and components of vehicle 2 (rather than to the electric propulsion system 30 of vehicle 2).

[0045] exist Figure 1 The text indicates the electrical connection component 1 of the vehicle 2's electrical system 20.

[0046] Figure 2 Examples Figure 1 The illustration shows a first perspective view of the electrical connection assembly 1 of the electrical system 20 of vehicle 2. In some places herein, for the sake of brevity and clarity, the electrical connection assembly 1 is simply referred to as assembly 1. Unless otherwise indicated below, reference is also made to... Figure 1 and Figure 2 .

[0047] According to the illustrated embodiment, the electrical connection assembly 1 includes four socket / connector pairs p1-p4, each socket / connector pair including sockets s1-s4 and connectors c1-c4 capable of connecting to the associated sockets s1-s4. In other words, according to the illustrated embodiment... In the implementation scheme, the electrical connection assembly 1 includes four connectors c1-c4 and four sockets s1-s4, wherein each of the four connectors c1-c4 can be connected to one of the four sockets s1-s4.

[0048] However, according to another embodiment, the electrical connection assembly 1 may include another number of socket / connector pairs p1-p4, such as a number between one and twenty, or a number between one and eight.

[0049] According to the illustrated embodiment, each socket / connector pair p1-p4 of the electrical connection assembly 1 is configured to electrically connect a group of battery cells of the energy storage system 18 of the vehicle 2 to the electric propulsion system 30 of the vehicle 2. However, according to another embodiment, one or more socket / connector pairs p1-p4 of the electrical connection assembly 1 may be configured to electrically connect other parts, components, systems or devices of the vehicle 2.

[0050] As mentioned, according to the illustrated embodiment, power system 20 is a high-voltage power system with a nominal voltage within a so-called voltage level B. Therefore, according to the illustrated embodiment, electrical connection assembly 1 can also be referred to as a high-voltage electrical connection assembly or a VCB electrical connection assembly. Similarly, connectors c1-c4 of electrical connection assembly 1 can also be referred to as high-voltage connectors or VCB connectors, and sockets s1-s4 of electrical connection assembly 1 can also be referred to as high-voltage sockets or VCB sockets.

[0051] exist Figure 2 In this diagram, each connector c1-c4 is illustrated as being in a non-connected state, in which connector c1-c4 is not connected to sockets s1-s4. As explained in detail below, each connector c1-c4 can be connected along... Figure 2 The indicated insertion direction id is inserted into sockets s1-s4.

[0052] Each connector c1-c4 of the electrical connection assembly 1 includes a connector body b1-b4 and a locking member m1-m4 movably arranged relative to the connector body b1-b4 between an unlocked position and a locked position. Figure 2 In the diagram, the locking components m1-m4 of connectors c1-c4 are illustrated as being in their respective locked positions.

[0053] As further explained below, locking members m1-m4 are configured to lock the corresponding connector c1-c4 to the socket s1-s4 when the connector c1-c4 is connected to the socket s1-s4 and the locking members m1-m4 are in the locked position.

[0054] Figure 3 Examples Figure 1 A second perspective view of the electrical connection assembly 1 of the electrical system 20 of the illustrated vehicle 2. Figure 3 In the diagram, each connector c1-c4 of the electrical connection assembly 1 is illustrated as being in a connected state, in which connector c1-c4 is connected to the sockets s1-s4 of the electrical connection assembly 1. Furthermore, in... Figure 3 In the diagram, the locking members m1-m4 of connectors c1-c4 are illustrated as being in their respective locked positions. Unless otherwise indicated below, reference will also be made to... Figures 1-3 .

[0055] As mentioned, in Figure 2 In this example, each connector c1-c4 is illustrated as being in a non-connected state, in which connector c1-c4 is not connected to socket s1-s4, and the locking members m1-m4 of connector c1-c4 are illustrated as being in the corresponding locked positions.

[0056] This is because, according to the illustrated embodiment, the locked position is the default position of the locking members m1-m4. That is, according to the illustrated embodiment, each locking member m1-m4 is configured to be in the locked position when no external force is applied to it. Furthermore, according to the illustrated embodiment, each locking member m1-m4 is formed by a latch flexibly arranged relative to the connector bodies b1-b4 between the locked and unlocked positions.

[0057] In other words, more specifically, each locking member m1-m4 is inherently flexible, allowing it to move from a locked position to an unlocked position by an external force acting on it. Furthermore, each locking member m1-m4 is configured to present the locked position through its own stiffness when such an external force is released.

[0058] like Figure 2As indicated, each socket s1-s4 of the electrical connection assembly 1 includes a notch n1-n4. Each notch n1-n4 is configured to move the locking member m1-m4 of the corresponding connector c1-c4 from a locked position to an unlocked position when the connector c1-c4 is inserted relative to the socket s1-s4.

[0059] Insertion direction ID is also present Figure 3 The instructions are as follows. Each connector c1-c4 can be inserted into the corresponding socket s1-s4 along the insertion direction id. According to the illustrated embodiment, each locking member m1-m4 is configured to bend in a direction substantially perpendicular to the insertion direction id during the insertion movement of the connector c1-c4 relative to the socket s1-s4 along the insertion direction id, through the abutment contact between the locking member m1-m4 and the corresponding notch n1-n4.

[0060] Furthermore, according to the illustrated embodiment, each locking member m1-m4 is configured to snap into the locking position when the connectors c1-c4 are fully inserted into the sockets s1-s4.

[0061] like Figure 2 As indicated, each locking member m1-m4 includes holes a1-a4. (As in the comparison...) Figure 2 and Figure 3 As can be seen, each hole a1-a4 is configured to receive the notch n1-n4 of the associated socket s1-s4 when the connector c1-c4 is connected to the socket s1-s4 and the locking member m1-m4 is in the locked position. For the sake of simplicity and clarity, Figure 3 The reference numerals for holes a1-a4 and notches n1-n4 are not included in the attached drawings.

[0062] As understood from the above description, according to the illustrated embodiment, each locking member m1-m4 is configured to snap into a locked position by the rigidity of the locking member m1-m4 when the connector c1-c4 is fully inserted into the socket s1-s4. In other words, according to the illustrated embodiment, when the connector c1-c4 of the electrical connection assembly 1 is fully inserted into the socket s1-s4, the locking member m1-m4 snaps into a locked position where the notch n1-n4 of the socket s1-s4 is received in the hole a1-a4 of the locking member m1-m4 of the connector c1-c4. The connector c1-c4 is thus locked to the socket s1-s4 by the abutment contact between the notch n1-n4 of the socket s1-s4 and the defining wall of the hole a1-a4 of the locking member m1-m4. In other words, the abutment contact between the notches n1-n4 of sockets s1-s4 and the defining walls of the holes a1-a4 of locking members m1-m4 prevents connectors c1-c4 from being removed from sockets s1-s4 by applying force to connectors c1-c4 in a direction opposite to the insertion direction id.

[0063] like Figure 2 and Figure 3 As illustrated, according to the illustrated embodiment, the electrical connection assembly 1 includes two clamping units 3, 3'. According to another embodiment, the electrical connection assembly 1 may include another number of clamping units 3, 3', such as one or a number between three and ten.

[0064] According to the embodiments described herein, the clamping units 3, 3' of the electrical connection assembly 1 and the connectors c1-c4 are configured such that the clamping units 3, 3' can only be mounted on the connectors c1-c4 when the locking members m1-m4 of the connectors c1-c4 are in the locked position.

[0065] exist Figure 2 and Figure 3 The mounting direction md of the corresponding clamping units 3 and 3' is indicated in the diagram. According to the illustrated implementation scheme, the corresponding clamping... The mounting direction md of unit 3, 3' is perpendicular to the insertion direction id of connectors c1-c4 of electrical connection assembly 1.

[0066] Figure 4 Examples Figure 3 A second perspective view of the illustrated electrical connection assembly 1, wherein the clamping units 3, 3' of the electrical connection assembly 1 are mounted on the connectors c1-c4 of the electrical connection assembly 1.

[0067] In other words, as mentioned, the locking components m1-m4 of each connector c1-c4 are in Figure 3 The middle is illustrated as being in the corresponding locked position. Therefore, the clamping units 3, 3' of the electrical connection assembly 1 can move along... Figure 3 and Figure 4 The indicated mounting orientation (md) is used on connectors c1-c4 of electrical connection assembly 1. Unless otherwise specified below, refer to [reference needed]. Figures 1-4 .

[0068] The clamping units 3 and 3' of the electrical connection assembly 1 may be referred to as the first clamping unit 3 and the second clamping unit 3'. According to the illustrated embodiment, the first clamping unit 3 and the second clamping unit 3' have the same design.

[0069] Similarly, the four socket / connector pairs p1-p4 of the electrical connection assembly 1 can be referred to as the first socket / connector pair p1, the second socket / connector pair p2, the third socket / connector pair p3, and the fourth socket / connector pair p4.

[0070] The socket s1 of the first socket / connector pair p1 may be referred to as the first socket s1, and the connector c1 of the first socket / connector pair p1 may be referred to as the first connector c1 of the electrical connection assembly 1. Similarly, the socket s2 of the second socket / connector pair p2 may be referred to as the second socket s2, and the connector c2 of the second socket / connector pair p2 may be referred to as the second connector c2 of the electrical connection assembly 1. Likewise, the socket s3 of the third socket / connector pair p3 may be referred to as the third socket s3, and the connector c3 of the third socket / connector pair p3 may be referred to as the third connector c3 of the electrical connection assembly 1. Similarly, the socket s4 of the fourth socket / connector pair p4 may be referred to as the fourth socket s4, and the connector c4 of the fourth socket / connector pair p4 may be referred to as the fourth connector c4 of the electrical connection assembly 1.

[0071] According to the illustrated embodiment, component 1 includes a socket mounting member 15, wherein each socket s1-s4 of the electrical connection component 1 is mounted on the socket mounting member 15. Figure 2 Best viewed from the perspective of the illustrated embodiment, the sockets s1 and s2 of the first socket / connector pair p1 and the second socket / connector pair p2 are... The sockets s3 and s4 of the third socket / connector pair p3 and the fourth socket / connector pair p4 are arranged adjacent to each other on the socket mounting member 15 along the installation direction md.

[0072] As understood from the description above, and using the terminology mentioned above, in Figure 4 In the process, the first clamping unit 3 is assembled on the first connector c1 and the second connector c2, and the second clamping unit 3' is assembled on the third connector c3 and the fourth connector c4.

[0073] Figure 5 Examples of references Figures 1-4 The third perspective view of the electrical connection assembly 1 as explained. Figure 5 In the third perspective view, connectors c1-c4 of electrical connection assembly 1 are partially inserted into the corresponding sockets s1-s4. That is, with Figure 1 Compared to the first perspective view, connectors c1-c4 are partially inserted into their respective sockets s1-s4 along the insertion direction id, but not yet fully inserted. Unless otherwise indicated below, reference is also made to... Figures 1-5 .

[0074] like Figure 5It is evident that each locking member m1-m4 is in the unlocked position. That is, more specifically, during the insertion of connectors c1-c4 into their respective sockets s1-s4, the abutment contact between the corresponding locking member m1-m4 and the notches n1-n4 of the corresponding sockets s1-s4 has engaged the locking member m1-m4 from its unlocked position. Figure 3 The illustrated locking position is shifted to Figure 5 The unlocking location is shown in the example.

[0075] Therefore, in Figure 5 In the described scenario, clamping units 3, 3' are mechanically prevented from being assembled onto connectors c1-c4 of the electrical connection assembly 1. More specifically, in Figure 5 In the described scenario, the first clamping unit 3 is mechanically prevented from being assembled onto the first connector c1 and the second connector c2 through the abutment contact between a portion 5 of the first clamping unit 3 and the locking member m1 of the first connector c1. Furthermore, in Figure 5 In the depicted scenario, the second clamping unit 3' is mechanically prevented from being assembled onto the third connector c3 and the fourth connector c4 through the abutment contact between a portion 5' of the second clamping unit 3' and the locking member m3 of the third connector c1. Figure 5 In the middle, a portion 5' of the second clamping unit 3' is hidden behind the first connector c1, but... Figure 2 and Figure 3 It is visible and indicated in the text.

[0076] Due to these features, the assembler or assembly machine can detect that the locking members m1 and m3 of the first connector c1 and the third connector c3 are not in the locked position. As mentioned, according to the illustrated embodiment, the locking members m1-m4 of connectors c1-c4 are configured to... The corresponding connectors c1-c4 are in a locked position when fully inserted into their associated sockets s1-s4. Therefore, the fact that clamping units 3, 3' are prevented from being assembled onto connectors c1-c4 indicates that connectors c1-c4 are not fully inserted into their associated sockets s1-s4. Furthermore, as understood from the above description, this problem can be solved by applying force to connectors c1-c4 in the insertion direction id to further insert connectors c1-c4 into sockets s1-s4.

Figures 1-6 .exist Figure 6In the third perspective view, the first connector c1 and the third connector c3 are fully inserted into the first socket s1 and the third socket s3, respectively, and the first clamping unit 3 is mounted on the first connector c1, and the second clamping unit 3' is mounted on the third connector c3. However, as... Figure 6 It can be seen that the abutment contact between a portion 5 of the first clamping unit 3 and the locking member m2 of the second connector c2 prevents the first clamping unit 3 from moving further along the mounting direction md.

[0078] exist Figure 6 In the middle, a portion 5' of the second clamping unit 3' is hidden behind the second connector c2. However, a portion 5' of the second clamping unit 3' is... Figure 2 and Figure 3 The instructions are in the middle. Figure 6 In the described scenario, the abutment contact between a portion 5' of the second clamping unit 3' and the locking member m4 of the fourth connector c4 prevents further movement of the second clamping unit 3' along the mounting direction md.

[0079] Therefore, in this way, the assembler or assembly machine can detect that the locking members m2, m4 of the second connector c2 and the fourth connector c4 are not in the locked position. This can be achieved by applying force to the second connector c2 and the fourth connector c4 in the insertion direction id to fully insert the second connector c2 and the fourth connector c4 into the second socket s2 and the fourth socket s4, respectively. Thus, the locking members m2, m4 of the second connector c2 and the fourth connector c4 will be in the corresponding locked position, and the first clamping unit 3 and the second clamping unit 3' can also be assembled onto the second connector c2 and the fourth connector c4 by applying force to the first clamping unit 3 and the second clamping unit 3' in the mounting direction md. As understood from the above description, after such a process, the first clamping unit 3 and the second clamping unit 3' will be in the locked position. Figure 4 The location illustrated.

[0080] Furthermore, as understood from the above description, according to the illustrated embodiment, the clamping units 3, 3' and connectors c1-c4 of the electrical connection assembly 1 The clamping units 3 and 3' are configured such that clamping units 3 and 3' can be mounted on two connectors c1-c4 only when the locking members m1-m4 of the two connectors c1-c4 are in their respective locked positions. According to another embodiment, the electrical connection assembly 1 can be configured such that clamping units 3 and 3' can be mounted on another number of connectors c1-c4 (such as one connector c1-c4 or three or more connectors c1-c4) when the locking members m1-m4 of the connectors c1-c4 are in their respective locked positions.

That is, the components of electrical connection assembly 1 are in... Figure 7 It has with Figure 6 The same relative position in. Figure 7 In the example, it is shown that in the context of... Figure 6 The electrical connection assembly 1 is seen in the direction opposite to the indicated installation direction md (i.e., in the direction perpendicular to the insertion direction id). Therefore, the installation direction is not in... Figure 7 The instructions are as follows. Unless otherwise indicated below, please refer to the following text. Figure 6 and Figure 7 .

[0082] As explained above, in Figure 6 and Figure 7 In the depicted scenario, the locking member m2 of the second connector c2 and the locking member m4 of the fourth connector c4 are in their respective unlocked positions. For example... Figure 7 It is clearly visible that the first clamping unit 3 is prevented from being assembled onto the second connector c2 by the abutment contact between a portion 5' of the first clamping unit 3 and the locking member m2 of the second connector c2. Similarly, the second clamping unit 3' is prevented from being assembled onto the fourth connector c4 by the abutment contact between a portion 5' of the second clamping unit 3' and the locking member m4 of the fourth connector c4.

[0083] Therefore, as is apparent from the above description, according to the illustrated embodiment, the locking members m1-m4 of each connector c1-c4 are configured such that when moved to the unlocked position, the locking members present a position relative to the connector bodies b1-b4 in which the locking members m1-m4 prevent the clamping units 3, 3' from being fitted onto the connectors c1-c4. Furthermore, according to the embodiments herein, the dimensions of the clamping units 3, 3' of the electrical connection assembly 1 and the connectors c1-c4 are designed such that the clamping units 3, 3' can only be fitted onto the connectors c1-c4 when the locking members m1-m4 of the connectors c1-c4 are in the locked position.

[0084] As mentioned in this article, the locking positions of locking components m1-m4 can also be referred to as the first position, default position, holding position, or locked position. Similarly, as mentioned in this article, the unlocking positions of locking components m1-m4 can also be referred to as... This is referred to as the second position, the bent position, the release position, or the unlock position.

[0085] Figure 8 Examples are given based on reference. Figures 1-7 A side view of the first clamping unit 3 of the electrical connection assembly 1 in the explained embodiment. Figure 8In the example, it is shown that in the context of... Figures 2-7 The first clamping unit 3 is seen in the direction that id, where the insertion directions id of the connectors c1-c4 of the indicated electrical connection assembly 1 are consistent (i.e., in the direction perpendicular to the mounting direction md of the first clamping unit 3). Unless otherwise indicated below, reference is also made to... Figures 1-8 .

[0086] As mentioned, according to the illustrated embodiment, the second clamping unit 3' is identical to the first clamping unit 3. In other words, the second clamping unit 3' includes the same features, functions, and advantages as the first clamping unit 3. However, for the sake of simplicity and clarity, only the reference numerals for the first clamping unit 3 are inserted in the figures. Figure 8 and Figure 9 In addition, in some places herein, for the sake of brevity and clarity, the first clamping unit 3 is simply referred to as "clamping unit 3". Furthermore, in some places herein, either the first clamping unit 3 or the second clamping unit 3' is simply referred to as "clamping unit 3, 3'".

[0087] According to the illustrated embodiment, the clamping unit 3 includes a U-shaped profile formed by a first arm 11, a second arm 12, and a connecting segment 13 connecting the first arm 11 and the second arm 12. The first arm 11 and the second arm 12 of the clamping unit 3 may also be referred to as a first arm portion and a second arm portion, or a first arm segment and a second arm segment.

[0088] The first arm 11, the second arm 12, and the connecting section 13 together define a receiving hole 14, wherein the receiving hole 14 is configured to receive the plurality of connectors c1, c2 of the electrical connection assembly 1 when the clamping unit 3 is assembled on the plurality of connectors c1, c2 along the mounting direction md. Figure 8 As can be seen, the opening of the receiving hole 14 is located between the distal end 7 of the first arm 11 and the second arm 12. Figure 2 and Figure 8 In the figure, for the sake of simplicity and clarity, only the distal end 7 of the first arm 11 is provided with reference numerals. Figure 2 The first arm 11' and the second arm 12' of the second clamping unit 3' are indicated in the middle, as well as the connecting section 13'.

[0089] As explained above, the electrical connection assembly 1 is configured such that if the locking members m1-m4 of connectors c1-c4 are in the locked position, the first clamping unit 3 is prevented from being mounted on connectors c1-c4 by the abutment contact between a portion 5 of the first clamping unit 3 and the locking members m1-m4 of connectors c1-c4. Figure 2 , Figure 7 and Figure 8 visible, According to the illustrated embodiment, a portion 5 of the first clamping unit 3 is located at the distal end 7 of the first arm 11 of the first clamping unit 3.

[0090] Similarly, as explained above, the electrical connection assembly 1 is configured such that if the locking members m1-m4 of connectors c1-c4 are in the locked position, the second clamping unit 3' is prevented from being mounted on connectors c1-c4 by the abutment contact between a portion 5' of the second clamping unit 3' and the locking members m1-m4 of connectors c1-c4. Figure 2 As can be seen, according to the illustrated embodiment, a portion 5' of the second clamping unit 3' is located at the distal end 7' of the first arm 11' of the second clamping unit 3'.

[0091] Furthermore, as understood from the description herein, when clamping units 3, 3' are assembled onto connectors c1-c4, clamping units 3, 3' are configured to abut against two opposing portions of connectors c1-c4. According to the illustrated embodiment, locking members m1-m4 are arranged on one of the two opposing portions. In other words, clamping units 3, 3' are configured to abut against a portion of connectors c1-c4, where locking members m1-m4 of connectors c1-c4 are arranged. This feature of clamping units 3, 3' being configured to abut against two opposing portions of connectors c1-c4 means that the surface normals of the two opposing portions are opposite to each other.

[0092] Furthermore, according to the illustrated embodiment, the clamping units 3, 3' and locking members m1-m4 of the connectors c1-c4 of the electrical connection assembly 1 are configured such that when the connectors c1-c4 are connected to the sockets s1-s4 and the clamping units 3, 3' are mounted on the connectors c1-c4, the clamping units 3, 3' prevent the locking members m1-m4 from moving from the locked position to the unlocked position.

[0093] Furthermore, according to the illustrated embodiment, the clamping units 3, 3' and connectors c1-c4 of the electrical connection assembly 1 are configured such that when the clamping units 3, 3' are assembled onto the connectors c1-c4, the clamping units 3, 3' apply a clamping force to the connectors c1-c4. In other words, according to the illustrated embodiment, the receiving hole 14 formed between the first arms 11, 11' and the second arms 12, 12' and the connection sections 13, 13' of the clamping units 3, 3' is slightly smaller than the external dimensions of each connector c1-c4 of the electrical connection assembly 1. The wording "slightly smaller" can mean that the receiving hole 14 is a fraction of a percent or a fraction of a percent smaller than the external dimensions of each connector c1-c4 of the electrical connection assembly 1.

[0094] Furthermore, as understood from the description above, the clamping units 3, 3' are flexible, such that when the clamping units 3, 3' are assembled onto connectors c1-c4, the clamping units apply a clamping force to the connectors c1-c4. According to the illustrated embodiment, the clamping units 3, 3' are formed of a polymer material. However, according to another embodiment, the clamping units 3, 3' may be formed of another type of material (such as metal).

[0095] Figure 9 Examples are given based on reference. Figures 1-8 A front view of the first clamping unit 3 of the electrical connection assembly 1 in the explained embodiment. Figure 9 In the example, it is shown that in the context of... Figure 8 as well as Figures 2-6 The first clamping unit 3 is seen in the direction opposite to the indicated installation direction md (i.e., in the direction perpendicular to the insertion direction id of the first clamping unit 3). Unless otherwise indicated below, reference will also be made to... Figures 1-9 .

[0096] As mentioned, according to the illustrated embodiment, the second clamping unit 3' is identical to the first clamping unit 3, and for the sake of simplicity and clarity, only the reference numerals for the first clamping unit 3 are inserted. Figure 8 and Figure 9 In addition, as mentioned, in some places in this article, for the sake of brevity and clarity, the first clamping unit 3 is simply referred to as "clamping unit 3".

[0097] like Figure 9 As indicated, clamping unit 3 includes a series of ridges r1-r5. The fact that the second clamping unit 3' includes a corresponding series of ridges can be seen, for example, in... Figure 2 and Figure 3 As seen in the image, when clamping units 3, 3' are assembled onto connectors c1-c4 of electrical connection assembly 1, a series of ridges r1-r5 prevents movement of clamping units 3, 3' in directions d1, d2 parallel to the insertion direction id. In other words, the series of ridges r1-r5 together form the inner contour of receiving hole 14, which substantially matches the outer contour of each connector c1-c4 of electrical connection assembly 1. Ribs r1-r5 of the series extend in a direction consistent with the mounting direction md of clamping units 3, 3'. In this way, if the locking members m1-m4 of connectors c1-c4 are in the locked position, clamping units 3, 3' can be easily assembled onto connectors c1-c4, while when clamping units 3, 3' are assembled onto connectors c1-c4, the series of ridges r1-r5 ensures that clamping units 3, 3' are locked relative to connectors c1-c4 in directions d1, d2 parallel to the insertion direction id of connectors c1-c4.

[0098] like Figure 2 As indicated, according to the illustrated embodiment, each connector c1-c4 of the electrical connection assembly 1 includes an actuator e1-e4. The actuators e1-e4 of connectors c1-c4 are relative to the connector bodies b1-b4 of connectors c1-c4. It can be movably positioned between the default position and the unlocked position. Figure 2 China and in Figures 3-7 In the diagram, the visible actuators e1-e4 of connectors c1-c4 are illustrated in their respective default positions. For the sake of simplicity and clarity, Figures 3-7 The actuators visible in the diagram are not marked with reference numerals.

[0099] Each actuator e1-e4 is operatively connected to the locking member m1-m4 of the corresponding connector c1-c4, such that when actuator e1-e4 moves from the default position to the unlocked position, the locking member m1-m4 of connector c1-c4 moves from the locked position to the unlocked position. According to the illustrated embodiment, actuator e1-e4 can be moved from the default position to the unlocked position by pressing actuator e1-e4 in a direction toward the associated socket s1-s4 (i.e., in a direction consistent with the insertion direction id of connector c1-c4) and toward the connector body b1-b4 of connector c1-c4.

[0100] As understood from the description above, when a user (such as an assembler or assembly machine) wants to remove the connected connectors c1-c4 from sockets s1-s4 (e.g., from... Figure 3 (As described above, the user can move the actuators e1-e4 of connectors c1-c4 from the default position to the unlocked position. Therefore, the locking members m1-m4 of connectors c1-c4 move from the locked position to the unlocked position. Consequently, the holes a1-a4 of the locking members m1-m4 move relative to the notches n1-n4, so that the notches n1-n4 are no longer located in the holes a1-a4. The user can then remove connectors c1-c4 from the socket by applying force to connectors c1-c4 in the direction opposite to the insertion direction id.)

[0101] According to the illustrated embodiment, clamping units 3, 3' and actuators e1-e4 are configured such that when clamping units 3, 3' are mounted on connectors c1-c4 including actuators e1-e4, clamping units 3, 3' prevent actuators e1-e4 from moving from the default position to the unlocked position.

[0102] According to the illustrated embodiment, this is achieved through two aspects of the clamping units 3, 3'. The first aspect of the clamping units 3, 3' is that, when the clamping units 3, 3' are mounted on the connectors c1-c4 including actuators e1-e4, the clamping units cover (i.e., prevent access to) the actuators e1-e4. Furthermore, in Figure 9 The text indicates the first ridge r1 of a series of ridges r1-r5. A second aspect of the clamping units 3, 3' is that, when the clamping units 3, 3' are assembled onto connectors c1-c4 including actuators e1-e4, the first ridge r1 mechanically prevents the actuators e1-e4 from moving by means of abutting contact between the first ridge r1 and the actuators e1-e4. Move from the default position to the unlocked position. In this way, it is ensured that when clamping units 3, 3' are mounted on connectors c1-c4, connectors c1-c4 will not be accidentally removed from sockets s1-s4.

[0103] As mentioned in this article, clamping units 3 and 3' can also be referred to as clamps, clamping devices, connector fixing units, connector retaining units, connector protective covers, etc.
