[0036] Figure 1 This is a schematic diagram of a connector system 100 in an assembled state according to an exemplary embodiment of the present invention. Figure 2 This is a schematic diagram of a connector system 100 in an unassembled state according to an exemplary embodiment of the present invention. Figure 3 This is an exploded perspective view of connector 1 according to an exemplary embodiment of the present invention.

[0037] Connector system 100 includes a connector 1 and a mating connector 2 that mates with connector 1. In some embodiments, connector system 100 is a high-power connector system that transmits power between components of a high-power circuit system. In some examples, connector system 100 is used in battery systems in electric vehicles or hybrid electric vehicles. It is understood that the application of connector system 100 is not limited to this.

[0038] Connector 1 can be electrically connected via cable 301 to components such as batteries, chargers, inverters, motors, or other types of components. Connector 2 can be electrically connected to other components, such as battery packs.

[0039] In connector system 100, connector 1 is removably connected to mating connector 2 for use in situations such as maintenance or repair. Connector 1 and mating connector 2 mate in a direction perpendicular to cable 301. When connector 1 and mating connector 2 mate, i.e., when connector system 100 is in an assembled state, terminal 106 in connector 1 contacts and connects with mating terminal 202 in mating connector 2.

[0040] Connector 1 includes a housing 101, which has a T-shaped structure and includes a mating end 111 and a cable end 121. The mating end 111 mates with the mating connector 2. The housing 101 may be made of aluminum or an aluminum alloy. A cable 301 extends from the cable end 121.

[0041] The bottom of the housing 101 is provided with an opening 111a (first opening). Specifically, the opening 111a is located at the bottom of the mating end 111 of the housing 101. The opening 111a is used to mate with the mating connector 2. Specifically, the opening 111a allows the mating connector 2 to be inserted into the housing 101 along the mating direction D3.

[0042] The rear end of housing 101 is provided with an opening 121a (second opening). Specifically, opening 121a is located at the rear end of cable end 121 of housing 101. Terminal 106 is inserted into housing 101 through the rear opening 121a. In the connector system assembled state, terminal 106 is used to overlap with the mating terminal 202 portion of mating connector 2.

[0043] The housing 101 has an opening 111b (a third opening) on ​​its side. Specifically, the opening 111b is located on the side of the mating end 111 of the housing 101. The opening 111b is used to allow a fastener 103 to be inserted into the housing 101. The fastener 103 is used to secure the terminal 106 in the connector 1 and the mating terminal 202 in the mating connector 2. The fastener 103 not only secures the terminal 106 and the mating terminal 202 to prevent displacement, but also presses the terminal 106 and the mating terminal 202 together to achieve a stable electrical connection. Figure 3 As shown, the fastener 103 is inserted into the housing 101 in the direction of D2.

[0044] exist Figure 3 In the example, the housing 101 has different openings on three different sides for the mating connector 2, terminal 106, and fastener 103 to be inserted, respectively. The terminal 106 is inserted into the housing 101 in the direction D1. Directions D1 and D2 point to two adjacent sides of the mating end 111, respectively, and direction D3 points to the top of the mating end 111. In other words, directions D1, D2, and D3 are perpendicular.

[0045] In some examples, fastener 103 includes bolt 113 and washer 104. Figure 3 In this example, bolt 113 and washer 104 are separate components. Bolt 113 is inserted into the interior of housing 101 through side opening 111b. Bolt 113 can pass through washer 104 and terminal 106 and be rotated into nut 105. It will be understood that in other examples, fastener 103 may include an integrally formed bolt and clamping components, simply securing the connector and mating connector through side opening 111b of housing 101.

[0046] Figure 3 The diagram also shows a sealing ring 107 in connector 1 for sealing between connector 1 and mating connector 2. Connector 1 also includes a plastic housing 108 located inside cable end 121. Connector 1 further includes a shielding ring 109, a sealing ring 119, a wire clamp 129, and a rear cover 139.

The rear cover 139 engages the sealing ring 119, the wire clamp 129, and the wire clamp 129 onto cable end 121, preventing the terminal 106 or cable 301 from being pulled out.

[0047] Figure 4 This is a partial schematic diagram of a connector 1 in an assembled state according to an exemplary embodiment of the present invention. To better illustrate the internal structure of the connector 1, Figure 4 Only the screw 133, nut 123, washer 104, terminal 106, and nut 105 of bolt 113 are retained.

[0048] exist Figure 4 In this configuration, the screw 133 of bolt 113 passes through washer 104 and terminal 106, and finally extends into the interior of nut 105 where it is secured. Washer 104 does not directly contact terminal 106. The space between washer 104 and terminal 106 (indicated by double arrows) allows mating terminals 202 of mating connector 2 to be inserted.

[0049] Figure 5 An exploded perspective view of a partial connector system according to an exemplary embodiment of the present invention is shown. To better illustrate the internal structure of the connector system, Figure 5 Only bolt 113, washer 104, mating terminal 202, terminal 106 and nut 105 are retained.

[0050] exist Figure 5In this assembly, terminal 106, bolt 113, and mating terminal 202 are inserted into the connector along different directions. Specifically, the insertion direction D1 of terminal 106, the insertion direction D2 of bolt 113, and the insertion direction D3 of mating terminal 202 intersect. In the assembled state, terminal 106 and mating terminal 202 partially overlap and make right-angle contact. Both terminal 106 and mating terminal 202 are plate-like structures, and a portion of surface 106a of terminal 106 contacts a portion of surface 202a of mating terminal 202. Figure 5 The arrangement of the center terminal 106 and mating terminal 202 increases the contact area. Furthermore, the electrical connection between connector 1 and mating connector 2 can be achieved solely through terminal 106 and mating terminal 202, reducing the consumption of conductive material and thus lowering costs.

[0051] like Figure 3 As shown, terminal 106 comprises a front end 116 and a rear end 126. The width of the front end 116 is smaller than the width of the rear end 126. In connector 1, the front end 116 is located in the mating end 111, and the rear end 126 is located in the cable end 121. The rear end 126 can be connected to the cable 301 by soldering. Figure 3 In one example, the front end 116 has a hole 136 for the bolt 113 to pass through, allowing the bolt 113 to be rotated and secured to the nut 105. In other examples, the front end 116 includes a U-shaped groove for the bolt 113 to pass through. Figure 3 In one example, the front end 116 structure of terminal 106 increases the contact area with mating terminal 202. In other examples, hole 136 may have a threaded structure that directly connects to bolt 113, thus eliminating the need for a nut.

[0052] Figure 6 A cross-sectional view of a partial connector system according to an exemplary embodiment of the present invention is shown. The washer 104, mating terminal 202, and terminal 106 all include hollow structures. A bolt 113 passes sequentially through the washer 104, mating terminal 202, and terminal 106, and is finally inserted into and threadedly connected to the nut 105. The bolt 113, nut 105, and washer 104 can be made of materials such as carbon steel or alloy steel. The terminal 106 and mating terminal 202 can be made of materials such as copper or copper alloys.

[0053] A gasket separates the nut 123 of bolt 113 from the mating terminal 202. In some examples, the gasket can be a cylinder with a hollow structure. In the example of connector 1, the gasket 104 has a bridge-type or frame-type structure. The gasket 104 includes a top plate 114 and two protruding ridges 124, 134 located at the bottom of the top plate 114 for pressing the mating terminal 202 under the tightening force of the bolt. Figure 5As shown, the top plate 114 of the gasket 104 includes chamfers 144 around its perimeter, which allows the gasket 104 to snap into the retainer of the connector.

[0054] Figure 7 A schematic diagram of a connector retainer according to an exemplary embodiment of the present invention is shown. Figure 8 A bottom view of a connector according to an exemplary embodiment of the present invention is shown.

[0055] In connector 1, connector retainer 102 is used to retain bolt 113, washer 104, terminal 106, and nut 105. For example... Figure 8 As shown, the connector retainer 102 has a bottom opening 152 (fourth opening) for the mating connector to be inserted. In some examples, such as Figure 7 As shown, the top of the connector retainer 102 is an open structure. In some other examples, the top of the connector retainer 102 is a closed structure. The connector retainer 102 includes a retainer housing 112 and a retainer base 132. The housing 112 includes a slot 122 for a terminal 106 to pass through and a hole 142 for a bolt 113 to pass through. The retainer base 132 has an opening 152.
