[0043] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0044] The electrical connector 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

[0045] like Figures 1-5 As shown, the electrical connector 1 according to an embodiment of the present invention includes a housing 10 and an electrical connector 20.

[0046] The housing 10 defines a receiving cavity 14, a first mating port and a second mating port 142, both of which are connected to the receiving cavity 14. An electrical connector 20 is disposed within the receiving cavity 14 and is configured to be at least partially a fractured melt.

[0047] A portion of the electrical connector 20 is adapted to be electrically connected to a first external component through a first mating port, and a portion of the electrical connector 20 is adapted to be electrically connected to a second external component through a second mating port 142, so as to realize the electrical connection between the first external component and the second external component using the electrical connector 20.

[0048] When one of the first external component and the second external component is a power source or is connected to a power source, current flows through the electrical connector 20 to the other of the first external component and the second external component, so as to enable the power source to supply power to the external component.

[0049] Specifically, the electrical connector 1 is used to realize the transmission of electrical energy. For example, when the electrical connector 1 is used in the battery pack of a vehicle, the electrical connector 1 serves as a power output port, a window that connects the battery pack to the vehicle and provides it with power.

[0050] Specifically, the electrical connector 20 is configured as at least partially a fracture-resistant fusible element, enabling the electrical connector 1 to function as a circuit protection device, quickly and effectively interrupting short-circuit and overload currents to prevent safety issues such as component damage or even fire during a short circuit.

[0051] Specifically, when the current through the electrical connector 20 is overloaded or short-circuited, the fusible element melts and the electrical connector 20 disconnects the transmission of electrical energy, thereby improving the safety of use.

[0052] The electrical connector 1 according to the present invention has both power transmission and safety functions, thus eliminating the need for additional safety components, reducing the number of parts, lowering costs, and saving space.

[0053] The electrical connector 1 according to a specific embodiment of the present invention is described below with reference to the accompanying drawings.

[0054] In some specific embodiments of this utility model, such as Figures 1-5 As shown, the electrical connector 1 includes a housing 10 and an electrical connector 20.

[0055] In some embodiments of this utility model, the electrical connector 20 can be fixed in the accommodating cavity 14 by a snap-fit ​​structure; or, the electrical connector 20 can be limited in the accommodating cavity 14 by a plastic structure; or, the electrical connector 20 can be injection molded and fixed in the accommodating cavity 14.

[0056] Of course, the electrical connector 20 can also be fixed in the accommodating cavity 14 in other ways, without much restriction here.

[0057] In some embodiments of this utility model, the electrical connector 20 is constructed as a molten body, which improves the sensitivity of the electrical connector 20 in responding to current overload or short circuit, thereby significantly improving safety and reliability.

[0058] Specifically, the electrical connector 20 is constructed as a molten body, which enables the electrical connector 20 to react more quickly when there is an overload or short circuit in the current, allowing it to cut off the current and stop the transmission of electrical energy more quickly, while preventing arcing in the high-voltage circuit from causing a secondary short circuit.

[0059] In some embodiments, after the fusible link on the electrical connector 20 is melted, the electrical connector 20 in the electrical connector 1 can be replaced separately, or the entire electrical connector 1 can be replaced directly. No further restrictions are imposed here.

[0060] In some embodiments of this utility model, such as Figure 4 As shown, a portion of the electrical connector 20 is exposed in the first mating port for electrical connection with the first external component, thus facilitating the electrical connection between the first external component and the electrical connector 20.

[0061] In some embodiments, the electrical connector 20 is applied to a battery pack, which includes a housing and a first external element. The first external element is located inside the housing, such that a portion of the electrical connector 20 is exposed through a first mating opening, so that the electrical connector exposed through the first mating opening can extend into the housing and be electrically connected to the first external element inside the housing to meet the electrical connection requirements of the first external element.

[0062] In some optional embodiments of this utility model, such as Figure 2 , Figure 3 As shown, the housing 10 includes a first housing portion 11 and an end cap 13. The first housing portion 11 has a receiving cavity 14 with a mounting port 15. The end cap 13 is used to open or close the mounting port 15. The second external component is adapted to extend into the receiving cavity 14 through the second mating port 142 and be fixedly connected to the electrical connector 20 and the second external component through the mounting port 15, so as to realize the fixed connection between the second external component and the electrical connector 20, and then realize the electrical connection between the first external component and the second external component through the electrical connector 20.

[0063] In some embodiments, such as Figure 3 As shown, the end cap 13 is detachably fixed to the housing 10 by the first fastener 61, so that the end cap 13 can open or close the mounting port 15.

[0064] In some examples, the first fastener 61 is a screw or bolt, the end cap 13 is provided with a first connecting hole, the first housing 11 is provided with a first mating hole, and the first fastener 61 is adapted to pass through the first connecting hole and the first mating hole to fix the end cap 13 to the first housing 11.

[0065] In some embodiments, the mounting port 15 and the second mating port 142 are located on two adjacent walls of the housing 10. The second external component enters the accommodating cavity 14 through the second mating port 142 and contacts and engages with the electrical connector 20 in the accommodating cavity 14. Then, the operator fixes the second external component and the electrical connector 20 from the mounting port 15 to prevent the second external component from accidentally disengaging from the electrical connector 20 under external force.

[0066] In some embodiments, the electrical connector 20 and the second external element are fixedly connected by a second fastener 62.

[0067] In some examples, the second fastener 62 is a screw, and the second external element includes an electrical connector 51 with a second connecting hole and an electrical connector 20 with a second mating hole. The second fastener 62 is adapted to pass through the second connecting hole and threadedly engage with the second mating hole to achieve a fixed connection between the electrical connector 51 and the electrical connector 20.

[0068] Furthermore, the second external component also includes a wiring harness 52, which is adapted to be welded and fixed to the electrical connector 51 for electrical connection with external parts.

[0069] In some specific embodiments of this utility model, such as Figure 3 , Figure 4 As shown, a first sealing element 351 is provided between the end cap 13 and the first housing portion 11 to seal the gap between the end cap 13 and the first housing portion 11, preventing liquid from entering the receiving cavity 14 from the gap between the end cap 13 and the first housing portion 11, thus avoiding short circuits in the electrical connector 1 and improving the safety of the electrical connector 1.

[0070] In some specific embodiments of this utility model, the electrical connector 1 further includes a fixing member 31, which is adapted to be fitted onto a second external element that is electrically connected to the electrical connector 20. The fixing member 31 is fixedly connected to the housing 10 to position the second external element. Thus, when the second external element is electrically connected to the electrical connector 20, the position of the second external element can be limited, reducing the possibility that the second external element may accidentally disengage from the electrical connector 20 due to external force.

[0071] In some embodiments, such as Figure 3 As shown, the housing 10 is provided with a connecting protrusion 16 protruding from the outer wall of the housing 10. The connecting protrusion 16 extends around the second mating port 142. The fixing member 31 cooperates with the connecting protrusion 16 to fix the fixing member 31 on the housing 10. The fixing member 31 is used to limit the relative position of the second external component and the housing 10 to achieve a stable electrical connection between the second external component and the electrical connector 20.

[0072] In some examples, the fastener 31 is threaded into the connecting protrusion 16 to facilitate operation of the fastener 31 and achieve a detachable fit between the fastener 31 and the connecting protrusion 16.

[0073] Specifically, when it is necessary to electrically connect the second external component to the electrical connector 20, first rotate the fixing member 31 to remove the fixing member 31 from the connecting protrusion 16, and then fix the fixing member 31 to the second external component. After the second external component extends into the receiving cavity 14 from the second mating port 142, rotate the fixing member 31 to fix the fixing member 31 to the connecting protrusion 16, thereby using the fixing member 31 to fix the second external component.

[0074] Furthermore, the fixing member 31 is provided with a sealing ring inside. When the fixing member 31 is fitted onto the second external component, the sealing ring undergoes elastic deformation, thereby achieving a fixed fit between the second external component and the fixing member 31. At the same time, it seals the gap between the second external component and the fixing member 31, preventing liquid from entering the receiving cavity 14 from the gap between the second external component and the fixing member 31, thus avoiding short circuits in the electrical connector 1 and improving the safety of the electrical connector 1.

[0075] In some optional embodiments of this utility model, such as Figure 3 , Figure 5 As shown, the electrical connector 1 also includes a snap fastener 32, which is fitted over the fixing member 31. When the fixing member 31 and the housing 10 are in place, the snap fastener 32 and the housing 10 are used to determine whether the fixing member 31 and the connecting protrusion 16 are installed in place, so as to avoid the fixing member 31 being misaligned or the torque between the fixing member 31 and the connecting protrusion 16 not being locked.

[0076] In some embodiments, the housing 10 is provided with a connecting protrusion 16 protruding from the outer wall of the housing 10. The connecting protrusion 16 extends around the second mating port 142. The fixing member 31 is threadedly engaged with the connecting protrusion 16. When the fixing member 31 and the connecting protrusion 16 are engaged in place, the snap-fit ​​engagement between the snap-fit ​​member 32 and the housing 10 is used to determine whether the fixing member 31 and the connecting protrusion 16 are installed in place, so as to avoid the fixing member 31 being misaligned or the torque between the fixing member 31 and the connecting protrusion 16 not being locked.

[0077] In some specific embodiments of this utility model, such as Figure 3 , Figure 5 As shown, the housing 10 is provided with a buckle protrusion 17, and the buckle 32 engages with the buckle protrusion 17.

[0078] Specifically, as the fastener 31 is gradually fixed to the connecting protrusion 16, the latching member 32 moves toward the latching protrusion 17. When the fastener 31 and the connecting protrusion 16 are in place, the latching member 32 and the latching protrusion 17 on the housing 10 are in place.

[0079] In some embodiments, the snap-fit ​​protrusion 17 is integrally formed with the housing 10, which eliminates the need for a connection structure between the snap-fit ​​protrusion 17 and the housing 10, thereby reducing the complexity of the components and ensuring the connection strength between the snap-fit ​​protrusion 17 and the housing.

[0080] In some specific embodiments of this utility model, such as Figure 3 As shown, the fastener 32 includes a first fastening part 321 and a second fastening part 322 that can be separably engaged. The first fastening part 321 and the second fastening part 322 are arranged circumferentially along the second engagement opening 142 to facilitate the fastener 32 being fitted onto the fixing member 31, thereby reducing the difficulty of operation.

[0081] In some examples, the first snap-fit ​​part 321 and the second snap-fit ​​part 322 engage with each other at the circumferential end of the second mating opening 142 to facilitate the connection and separation of the first snap-fit ​​part 321 and the second snap-fit ​​part 322, thereby facilitating the attaching of the snap-fit ​​part 32 to the fixing member 31 or the removal of the snap-fit ​​part 32 from the fixing member 31.

[0082] In some optional embodiments of this utility model, such as Figure 3 As shown, the housing 10 includes a first housing portion 11 and a second housing portion 12. The second housing portion 12 is disposed within the first housing portion 11 and defines a receiving cavity 14. A second mating port 142 penetrates the walls of the first housing portion 11 and the second housing portion 12, which are disposed opposite to each other, so that a second external component can extend into the second housing portion 12 through the second mating port 142 to be electrically connected to the electrical connector 20 in the receiving cavity 14.

[0083] In some embodiments, the connecting protrusion 16 is provided on the first housing portion 11. Specifically, the receiving cavity 14 defined by the second housing portion 12 matches the shape of the electrical connector 20. By providing the connecting protrusion 16 on the first housing portion 11, the receiving cavity 14 can be formed on the second housing portion 12 and the connecting protrusion 16 can be formed on the first housing portion 11, which helps to reduce molding difficulty and thus reduce production costs.

[0084] In some embodiments, the second shell portion 12 is fixed inside the first shell portion 11 by a snap-fit ​​structure.

[0085] In some specific embodiments of this utility model, such as Figure 3 , Figure 4 As shown, the first housing portion 11 is provided with a clearance opening, and the second housing portion 12 is provided with a mating protrusion 121. The mating protrusion 121 defines a second mating opening 142. The mating protrusion 121 passes through the clearance opening so that the second mating opening 142 is exposed outside the first housing portion 11, so as to facilitate the first external component to be electrically connected to the electrical connector 20 through the second mating opening 142.

[0086] In some embodiments, the housing includes a mounting wall 40, which has a mating opening 41. Multiple battery cells are disposed in the housing, and an external connection end is provided at the positive or negative terminal of the battery module formed by the multiple battery cells. The external connection end is adapted to be electrically connected to the electrical connector 20 through the first mating opening.

[0087] The external connection end is located inside the housing, and the mating protrusion 121 is adapted to extend into the housing through the mating port 41 to be electrically connected to the external connection end inside the housing.

[0088] In some specific embodiments of this utility model, such as Figure 3 , Figure 4 As shown, a second seal 352 is provided between the electrical connector 20 and the second housing 12. The second seal 352 is used to seal the gap between the electrical connector 20 and the second housing 12, thereby improving the sealing performance of the electrical connector 20 and facilitating the improvement of the safety of the use of the electrical connector 1.

[0089] Furthermore, a second seal 352 is provided between the electrical connector 20 and the second housing 12, which can also be used to separate the electrical connector 20 and the second housing 12 to avoid short circuit.

[0090] In some specific embodiments of this utility model, such as Figure 3 , Figure 4 As shown, a third seal 353 is provided between the first housing portion 11 and the second housing portion 12. The third seal 353 is used to seal the gap between the first housing portion 11 and the second housing portion 12 to prevent liquid from flowing into the receiving cavity 14 through the gap between the first housing portion 11 and the second housing portion 12, and to prevent liquid from flowing into the electrical connector 20, thereby improving the safety of the use of the electrical connector 1.

[0091] In some examples, such as Figure 4As shown, the third seal 353 is fitted over the mating protrusion 121 to seal the gap between the mating protrusion 121 and the first housing 11, preventing liquid from entering the first housing 11 through the gap between the mating protrusion 121 and the first housing 11, thereby improving the safety of the electrical connector 1 in use.

[0092] The electrical connection assembly 100 according to an embodiment of the present invention is described below. The electrical connection assembly 100 according to an embodiment of the present invention includes an electrical connector 1 and a connecting wire harness 50 according to the above embodiment of the present invention.

[0093] One end of the connecting harness 50 is electrically connected to the electrical connector 20, and the other end extends out of the receiving cavity through the second mating port 142, so that the other end of the connecting harness 50 can be electrically connected to the external component. Thus, the connecting harness 50 is used to realize the electrical connection between the electrical connector 1 and the external component, so that when the electrical connector 1 is electrically connected to the battery cell, the external component and the battery cell can be electrically connected. This allows the current in the battery cell to flow to the external component through the connecting harness 50 to power the external component.

[0094] It should be explained here that the connecting harness 50 defines the aforementioned second external component.

[0095] According to the embodiment of the present invention, the electrical connection assembly 100 utilizes the electrical connector 1 according to the above embodiment of the present invention, enabling the electrical connector 1 to simultaneously have the functions of transmitting electrical energy and providing protection.

[0098] It should be explained here that the external connection end defines the first external element mentioned above, and the connecting harness 50 defines the second external element mentioned above.

[0099] In some embodiments, the battery pack includes two electrical connectors 1 and two connecting harnesses 50, and multiple battery cells form a battery module.

[0100] The external component is adapted to mate with two connecting harnesses 50 so that electrical energy in the battery pack is transferred to the external component through the electrical connector 1 and the connecting harnesses 50 to provide electrical energy to the external component.

[0101] According to the battery pack of the present invention, by utilizing the electrical connector 1 of the above embodiment of the present invention, the electrical connector 1 can simultaneously have the functions of transmitting electrical energy and providing protection.
