DETAILED DESCRIPTION

[0016] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0017] See also Figures 1 to 3 ,in Figure 1 It is a schematic diagram of the overall structure of the wiring terminal of the utility model suitable for electrical connection of the fuel cell pole ear; Figure 2 It is a schematic diagram of the installation structure of the terminal body of the utility model; Figure 3 It is a schematic diagram of the installation structure of the main locking block of the utility model.

[0018] The utility model provides a terminal block for electrical connection of a fuel cell pole lug, comprising a terminal body 101, a sheath 102, a locking assembly and a connecting assembly, wherein the terminal body 101 is mounted on the sheath 102, and the locking assembly is mounted on the sheath 102. The material of the terminal body 101 is a copper terminal, and the terminal body 101 supports the connecting assembly, so that the terminal body 101 can be conveniently inserted into the sheath 102 through the connecting assembly; the material of the sheath 102 is a metal material, and the sheath 102 can be connected to metal plates with equal spacing, and the sheath 102 has terminal holes, which can be arranged in a single row or in double rows, so as to realize electrical connection of plates with narrow spacing, and the sheath 102 is a separated TPA, which is stably inserted into the metal plate through the locking assembly.

[0019] Among them, the connecting component includes a first chamfering block 103, a second chamfering block 104, a first press pin 105 and a second press pin 106, the first chamfering block 103 is installed on the terminal body 101, the second chamfering block 104 is installed on the terminal body 101, the first press pin 105 is installed on the terminal body 101, and is located at one end of the terminal body 101 away from the first chamfering block 103, and the second press pin 106 is installed on the terminal body 101, and is located at one end of the terminal body 101 away from the second chamfering block 104. The first chamfering block 103 and the second chamfering block 104 facilitate the insertion of the terminal body 101 into the sheath 102. After the terminal body 101 is plugged into the metal plate, the first chamfering block 103 and the second chamfering block 104 enable the terminal body 101 to occupy as little space in the width direction as possible after opening, so that the terminal body 101 is suitable for entering a narrow space, such as between the lug plates of a fuel cell. In addition, the first chamfering block 103 and the second chamfering block 104, as well as the elastic arm design at the front end of the terminal body 101, provide a stronger positive force at the place where the terminal body 101 contacts the metal plate, thereby reducing the contact resistance, not affecting signal acquisition, and improving the stability of the electrical connection. The first crimping foot 105 and the second crimping foot 106 facilitate crimping connection with an external wire.

[0020] Secondly, the connection assembly further includes an anti-error guide block 107, which is fixedly mounted on the terminal body 101. The anti-error guide block 107 is made of metal and is mounted on the terminal body 101 by welding. The anti-error guide block 107 can better ensure that the terminal body 101 is inserted into the sheath 102 without causing the terminal body 101 to be inserted in the wrong direction.

[0021] Again, the locking assembly includes a main locking block 108, a secondary locking block 109 and a locking block 110. The main locking block 108 is fixedly mounted on the sheath 102; the secondary locking block 109 is fixedly mounted on the sheath 102; and the locking block 110 is fixedly mounted on the sheath 102. The main locking block 108 is made of metal and is mounted in the sheath 102 by welding. The main locking block 108 clamps the terminal body 101 in the sheath 102; the secondary locking block 109 is made of metal and is mounted in the sheath 102 by welding. The secondary locking block 109 clamps the terminal body 101 for a second time, so that the terminal body 101 is not easily dislodged from the sheath 102; the locking block 110 firmly mounts the sheath 102 on the metal plate and is not affected by the shaking and bumping generated during the driving of the vehicle.

[0022] Next, the terminal body 101 has a main locking groove 111, which is located on one side of the terminal body 101 close to the main locking block 108, and the main locking groove 111 cooperates with the main locking block 108. The main locking groove 111 cooperates with the main locking block 108 to enable the terminal body 101 to be clamped in the sheath 102.

[0023] Then, the terminal body 101 has a secondary locking groove 112, which is located on one side of the terminal body 101 close to the secondary locking block 109, and the secondary locking groove 112 cooperates with the secondary locking block 109. The secondary locking groove 112 cooperates with the secondary locking block 109 to strengthen the clamping of the terminal body 101 on the sheath 102, so that the terminal body 101 is not easy to fall out of the sheath 102.

[0024] When the wiring terminal for electrical connection of a fuel cell pole ear of this embodiment is used, the sheath 102 is inserted into the metal plate through the locking block 110, so that the sheath 102 is stably assembled on the metal plate and is not affected by the shaking and bumping generated during the driving of the vehicle. Then, the terminal body 101 is inserted into the sheath 102, and under the action of the anti-mistake guide block 107, the terminal body 101 is placed in the sheath 102 in the correct direction, and the first chamfering block 103 and the second chamfering block 104 facilitate the insertion of the terminal body 101 into the sheath 1 02, so that the place where the terminal body 101 contacts the metal plate has a stronger positive force. After the terminal body 101 is stably inserted into the sheath 102, the main locking groove 111 is engaged with the main locking block 108, and the secondary locking groove 112 is engaged with the secondary locking block 109, so that the terminal body 101 is locked in the sheath 102, and the first crimping foot 105 and the second crimping foot 106 realize crimping connection with the external wire, so that the place where the terminal body 101 contacts the metal plate has a stronger positive force, which will not affect signal acquisition and improve the stability of the electrical connection.
