Technical Field
[0001] This utility model relates to a connector, and more particularly to a reinforced connector. Background Technology
[0002] Anderson connectors are commonly used in power systems such as batteries, charging systems, and electric vehicles. Anderson connectors are robust and capable of high current transmission, thus handling high-power applications and providing reliable connections while significantly reducing energy loss. Anderson connectors use a plug-in connection, simplifying installation and maintenance. Furthermore, Anderson connectors are available in various sizes to meet specific current requirements and application scenarios.
[0003] Existing Anderson connectors are available in various specifications based on rated current, including 50A, 120A, 175A, and 350A. However, existing Anderson connectors can generate sparks during connection or disconnection due to instantaneous voltage differences between terminals. Over time, this can cause melting and damage to the terminals and housing, leading to short circuits and difficulties in insertion and removal. Therefore, improving these shortcomings and enhancing the durability of Anderson connectors has become an important development goal. Utility Model Content
[0004] This invention provides a reinforced connector that adds an additional auxiliary terminal to the original specifications, which can improve the sparking phenomenon during contact. In addition, the auxiliary terminal can also increase the current.
[0005] This utility model discloses a reinforced connector, comprising a housing, two main terminals, two first auxiliary terminals, and two second auxiliary terminals. The housing has two parallel channels extending through opposite sides of the housing. The two main terminals are respectively disposed in the two channels, each adapted to slide along its respective channel. The two first auxiliary terminals are respectively disposed on the first side of the two channels and coupled to the two main terminals. The two second auxiliary terminals are respectively disposed on the second side of the opposite first side of the two channels and coupled to the two main terminals. Parts of the two first auxiliary terminals protrude from the ends of the two main terminals, and two first pieces of the two second auxiliary terminals engage with the ends of the two main terminals, with two second pieces of the two second auxiliary terminals also protruding from the ends of the two main terminals.
[0006] In one embodiment of the present invention, the outer shell has two grooves that are respectively connected to two channels and the two second pieces of the two second auxiliary terminals cover the two grooves.
[0007] In one embodiment of this utility model, the inner diameter of each of the above-mentioned sliding grooves is larger than the outer diameter of each of the first auxiliary terminals.
[0008] In one embodiment of the present invention, each of the main terminals has a receiving portion and a contact portion, the receiving portion facing the entrance of the channel, and the contact portion formed at one end of the receiving portion and extending towards the exit of the channel.
[0009] In one embodiment of the present invention, the aforementioned receiving portion is adapted to receive a cable, the cable transmitting current to the receiving portion and shunting it to the contact portion, the first auxiliary terminal, and the second auxiliary terminal.
[0010] In one embodiment of the present invention, each of the above-mentioned contact portions has a guide surface and a snap-fit surface, the guide surface and the snap-fit surface are formed at the end of the contact portion away from the receiving portion, and the snap-fit surface faces the receiving portion.
[0011] In one embodiment of the present invention, each of the first auxiliary terminals has a curved surface that extends toward the main terminal.
[0012] In one embodiment of the present invention, each of the second auxiliary terminals has a receiving surface, the width of which is greater than the width of the curved surface.
[0013] Based on the above, the reinforced connector of this utility model adopts a terminal structure consisting of a main terminal, a first auxiliary terminal, and a second auxiliary terminal. When two reinforced connectors are connected to each other, the first auxiliary terminal and the second auxiliary terminal of one reinforced connector respectively contact the second auxiliary terminal and the first auxiliary terminal of the other reinforced connector to achieve initial coupling. Then, the multiple main terminals of the two reinforced connectors are coupled to each other. Since the first auxiliary terminal and the second auxiliary terminal are already interconnected, the potentials of the multiple main terminals are the same and there is no voltage difference. This improves the spark phenomenon generated when existing connectors come into contact and increases the service life of the reinforced connector.
[0014] Furthermore, the reinforced connector of this utility model includes a main terminal, a first auxiliary terminal and a second auxiliary terminal, which has a larger current transmission capacity under the same volume specifications, thus improving the practicality of the reinforced connector of this utility model.

[0042] Please refer to Figure 1 and Figure 2The reinforced connector 100 of this utility model is applied to various electrical devices such as batteries, charging systems, and electric vehicles. For example, one reinforced connector is installed in the electrical device, and the other reinforced connector is coupled to the cable of the charging system. The two reinforced connectors are then snapped together. At this time, the current of the charging system can be transmitted to the electrical device through the cable and the two reinforced connectors to achieve the purpose of power supply.
[0043] refer to Figure 1 and Figure 2 The reinforced connector 100 includes a housing 110, two main terminals 120, two first auxiliary terminals 130, and two second auxiliary terminals 140. The housing 110 has two channels CH, which are parallel to each other and extend through opposite sides of the housing 110, forming a barrier between the two channels CH. The two main terminals 120 are respectively disposed in the two channels CH, wherein each main terminal 120 is adapted to slide along its respective channel CH. The two first auxiliary terminals 130 are respectively disposed on a first side S1 of the two channels CH and coupled to the two main terminals 120. The two second auxiliary terminals 140 are respectively disposed on a second side S2 of the opposite first side S1 of the two channels CH and coupled to the two main terminals 120.
[0044] Two first auxiliary terminals 130 protrude from the ends of two main terminals 120, and two first pieces of two second auxiliary terminals 140 are snapped into the ends of two main terminals 120, with two second pieces of two second auxiliary terminals 140 protruding from the ends of two main terminals 120.
[0045] The housing 110 has two grooves SG, which are respectively connected to two channels CH. The two second pieces of the two second auxiliary terminals 140 cover the two grooves SG. The outer diameter D1 of each second auxiliary terminal 140 is greater than the inner diameter D2 of each groove SG, and the inner diameter D2 of each groove SG is greater than the outer diameter D3 of each first auxiliary terminal 130.
[0046] refer to Figure 1 and Figure 3 Each main terminal 120 has a receiving portion 121 and a contact portion 122. The receiving portion 121 faces the inlet IL of the channel CH, and the contact portion 122 is formed at one end of the receiving portion 121 and extends towards the outlet OL of the channel CH. (See reference) Figure 4 and Figure 5 The receiving portion 121 is adapted to receive and is coupled to the cable 200. The cable 200 transmits current CR to the receiving portion 121 and is shunt to the contact portion 122, the first auxiliary terminal 130 and the second auxiliary terminal 140.
[0047] In addition, the receiving portion 121 clamps the output end of the cable 200, and each contact portion 122 has a guide surface GS and a snap-fit surface FS. The guide surface GS and the snap-fit surface FS are formed at the end of the contact portion 122 away from the receiving portion 121, and the snap-fit surface FS faces the receiving portion 121. In short, the guide surface GS and the snap-fit surface FS have opposite inclination directions. The guide surface GS is inclined towards the outlet OL of the channel CH, while the snap-fit surface FS is inclined towards the receiving portion 121.
[0048] refer to Figure 1 and Figure 3 Each first auxiliary terminal 130 has a curved surface 131 that extends toward the main terminal 120. Each second piece of each second auxiliary terminal 140 has a receiving surface 141, the width of which is greater than the width of the curved surface 131.
[0049] refer to Figures 3 to 5 The following describes the connection process of the two reinforced joints.
[0050] refer to Figure 3 Two reinforced connectors 100 are aligned in opposite vertical positions. At this time, the multiple main terminals 120 of the two reinforced connectors 100 correspond to each other, and each second auxiliary terminal 140 is aligned with each first auxiliary terminal 130. The two main terminals 120, each first auxiliary terminal 130 and each second auxiliary terminal 140 of each reinforced connector 100 are coupled to the corresponding main terminals 120. Multiple cables 200 are respectively arranged on the corresponding main terminals 120, and according to the positive and negative polarity specifications of the cables 200, the corresponding main terminals 120, first auxiliary terminals 130 and second auxiliary terminals 140 are made conductive to form the same potential.
[0051] refer to Figure 4 The two reinforced connectors 100 are brought closer together, causing the two housings 110 to abut against each other. Then, the two main terminals 120 are pushed closer together, and at the same time, the two main terminals 120 cause the corresponding first auxiliary terminals 130 and the second pieces of the second auxiliary terminals 140 to come into contact with each other to achieve the purpose of conduction. Since the width of the receiving surface 141 of the second piece of the second auxiliary terminal 140 is greater than the width of the curved surface 131 of the first auxiliary terminal 130, it is not easy to generate sparks under the premise of surface contact.
[0052] refer to Figure 5 The two reinforced connectors 100 continue to approach each other until the two guide surfaces GS of the two main terminals 120 come into contact with each other, while the bent surfaces 131 of each first auxiliary terminal 130 enter the corresponding grooves SG to compress the receiving surfaces 141 of each second piece of each second auxiliary terminal 140.
[0053] Finally, refer to Figure 6The two snap-fit surfaces FS of the two main terminals 120 interlock with each other, so that the two reinforced connectors 100 are connected as one unit. At this time, one of the cables 200 transmits current CR to the receiving part 121 and is shunted to the contact part 122, the first auxiliary terminal 130 and the second auxiliary terminal 140. Then, the three currents CR are shunted to the other cable 200 through the other contact part 122, the other first auxiliary terminal 130 and the other second auxiliary terminal 140 to complete the transmission of current CR.
[0054] In summary, the reinforced connector of this utility model adopts a terminal structure consisting of a main terminal, a first auxiliary terminal, and a second auxiliary terminal. When two reinforced connectors are connected to each other, the first and second auxiliary terminals of one reinforced connector respectively contact the second and first auxiliary terminals of the other reinforced connector to achieve initial coupling. Then, the multiple main terminals of the two reinforced connectors are coupled to each other. Since the first and second auxiliary terminals are already interconnected, the potentials of the multiple main terminals are the same and there is no voltage difference. This improves the sparking phenomenon generated when existing connectors come into contact, thereby increasing the service life of the reinforced connector.
[0055] Furthermore, the reinforced connector of this utility model includes a main terminal, a first auxiliary terminal and a second auxiliary terminal, which has a larger current transmission capacity under the same volume specifications, thus improving the practicality of the reinforced connector of this utility model.
