[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0042] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text is to include three parallel solutions. Taking "A and / or B" as an example, it includes solution A, or solution B, or a solution that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] In some exemplary technologies, the stack bipolar plate and the cell voltage monitoring (CVM) controller are mainly connected by an electrical connector. When connecting, the bipolar plate is first inserted into the electrical connector, and then the signal or electrical energy is transmitted to the CVM control device through the wires for data and energy conversion.

[0044] At present, the commonly used hydrogen fuel cell stack plates are mainly made of graphite or metal pole pieces, and the connection of graphite electrodes is mainly to open a hole in the graphite and insert a square or flat contact terminal connected with a wire into the hole of the graphite electrode to make it conductive.

[0045] However, the contact terminals of this connection structure are directly inserted into the mounting holes of the electrode plates. During driving of the vehicle, the contact terminals may automatically fall off, resulting in momentary disconnection. Furthermore, the contact terminals are not completely fixed to the electrodes, and the contact terminals may easily fall off from the electrode plates or the welded wires may fall off due to force, which results in poor connection stability of the electrical connector.

[0046] In order to improve the connection stability of the electrical connector and avoid the contact terminal from detaching from the electrode plate, which may cause the connection of the electrical connector to be unstable, the present invention proposes an electrical connector suitable for connecting various electronic devices, especially an electrical connector for connecting the electrode plate and the battery voltage monitoring controller in the field of electric vehicle hydrogen fuel cells.
