Abstract
Description
Technical Field
[0001] This invention relates to the field of electrical connections, and more specifically, to a rectangular copper busbar 90-degree side-outlet single-ended waterproof electrical connector socket. Background Technology
[0002] Since the battery pack accounts for the highest cost of a new energy vehicle, and the risk factor of the battery pack is also relatively high during use, many OEMs have proposed that the battery pack connector should have a single-end waterproof function in order to provide better protection for the vehicle battery pack.
[0003] The so-called single-ended waterproof function means that when the electrical connector socket is installed in the battery pack, even if water accumulates inside the socket cavity, water cannot flow into the battery pack, and even if the entire battery pack is immersed in water to a depth of 1 meter, water still cannot penetrate the battery pack. Single-ended waterproof function has been achieved in high-current and low-current electrical connectors. However, in the stamping of high-current surface-mount terminal connectors, only socket terminals can be used, and this scenario additionally requires the socket to be connected to the copper busbar side for wiring. Currently, there is no technical solution to achieve single-ended waterproofing. Summary of the Invention
[0004] This invention overcomes the shortcomings of existing high-current flat-type terminal electrical connectors, which cannot achieve single-end waterproofing. It provides a rectangular copper busbar 90-degree side-outlet single-end waterproof electrical connector socket, which is expected to solve the problems existing in the prior art.
[0005] To solve the above-mentioned technical problems, one embodiment of the present invention adopts the following technical solution:
[0006] A rectangular copper busbar 90-degree side-out single-ended waterproof electrical connector socket includes a socket insulator, a short-circuit signal socket, a signal terminal sealing body, a socket housing, a double-ended power socket, a socket end cover, a power terminal baffle, a power terminal TPA, a power terminal sealing body, and a power busbar conversion assembly.
[0007] The socket insulator is fixed with a short-circuit signal socket and a signal terminal sealing body, and the signal terminal sealing body is a rectangular structure.
[0008] The socket insulator is equipped with dual-head power sockets and power terminal baffles on both sides, and the socket insulator is installed in the socket housing;
[0009] The power terminal sealing body is installed on the power conversion copper busbar assembly, and the power conversion copper busbar assembly and the power terminal TPA are installed in the socket end cover;
[0010] The socket housing and the socket end cap are inserted and assembled.
[0011] By installing the power terminal sealing body onto the power conversion copper busbar assembly, and then installing the power conversion copper busbar assembly into the socket end cover, and finally inserting the socket housing with the socket insulator and the socket end cover into the assembly, single-end waterproofing of the rectangular copper busbar side-outlet 90-degree socket can be achieved without using complex processes such as potting, plastic sealing, and encapsulation. This effectively solves a problem in the industry.
[0012] A further technical solution is that the power switching copper busbar assembly includes a left power switching copper busbar assembly and a right power switching copper busbar assembly;
[0013] The left-turn power copper busbar assembly consists of a left-turn power copper busbar and a press-fit nut;
[0014] The left-turn power copper busbar is formed by stamping copper alloy sheet in one piece. The left-turn power copper busbar consists of an insertion part, a connecting part, and a screw-in plane. The insertion part and the connecting part are located on the same plane, and the screw-in plane and the connecting part plane have a 90° angle.
[0015] The press-fit nut is riveted and fixed to the screw plane of the left-hand power copper busbar. The connecting part is provided with a power terminal sealing body receiving groove, and the power terminal sealing body is installed in the power terminal sealing body receiving groove.
[0016] The right-side power busbar assembly is mirror-symmetrical to the left-side power busbar assembly.
[0017] The difference between the aforementioned power transfer copper busbar and existing copper busbars is that the power transfer copper busbar is formed by stamping copper alloy sheet in one piece, the elastic contact part and other parts of the substrate have a stepped thickness transition, and the rounded corners of the sealing contact part and the pre-positioning groove of the copper busbar are also formed by stamping in one piece.
[0018] Compared with the existing process of stamping copper busbars to the same thickness first and then machining them locally, this method can effectively improve production efficiency and reduce manufacturing costs.
[0019] A further technical solution is that the single-ended waterproof electrical connector socket also includes a sealing gasket;
[0020] The sealing gasket is installed between the socket insulator and the socket housing.
[0021] The sealing gasket prevents potential water leakage between the socket insulator and the socket housing, thus improving the waterproof performance of the connector socket.
[0022] A further technical solution is that the single-ended waterproof electrical connector socket also includes a socket sealing ring;
[0023] The bottom surface of the socket housing is provided with a sealing ring mounting groove, and the socket sealing ring is installed in the sealing ring mounting groove.
[0024] The sealing ring is used to further prevent possible water leakage between the socket housing and the socket end cap, thus further improving the waterproof performance of the connector socket.
[0025] A further technical solution is that a sealing lip is provided on the outer side of the signal terminal sealing body.
[0026] A further technical solution is that the power terminal sealing wire body is provided with an inner sealing lip and the outer sealing lip is provided.
[0027] A further technical solution is that an assembly error prevention structure is provided between the socket housing and the socket insulator;
[0028] The socket insulator is provided with an assembly error prevention groove at the signal terminal sealing body.
[0029] The aforementioned error-proof structures can all employ a matching boss and groove design to prevent errors, effectively reducing assembly mistakes, lowering assembly gaps, and improving waterproof performance.
[0030] A further technical solution is that the short-circuit signal jack has a rectangular hollow structure and is equipped with external elastic teeth;
[0031] The socket insulator is provided with a terminal bracket, and the elastic hanging teeth are engaged and fixed with the terminal bracket in the socket insulator.
[0032] A further technical solution is that the dual-head power socket has a symmetrical structure, consisting of a contact guide, an elastic contact, and a copper alloy substrate. The dual-head power socket has elastic contact at both ends, which can simultaneously match with the male plug terminal to achieve current transmission.
[0033] A further technical solution is that the socket housing and the socket tail cover are respectively provided with matching buckle hanging slots and buckle hanging platforms.
[0034] Once the buckle slot engages with the buckle mounting platform, the assembly between the two components is complete.
[0035] Compared with the prior art, the present invention has at least the following beneficial effects: The present invention achieves single-end waterproofing of a rectangular copper busbar 90-degree side-outlet socket without using complex processes such as potting, plastic sealing, and encapsulation. All parts of the present invention that are at risk of leakage are sealed and protected by assembled sealing parts, resulting in excellent waterproofing. Furthermore, the present invention fully considers the problems in the assembly process, and uses error-proof structures and various snap-fit structures to realize the installation of the connector socket, resulting in low assembly difficulty and high assembly accuracy.
