An electrical connector having a connector housing and a lever. The connector housing has a first wall, a second wall and side walls which extend between the first wall and the second wall. Multiple contacts are positioned in contact receiving cavities of the housing. The multiple contacts have wires which extend therefrom. A lever is rotatably mounted relative to the connector housing. The lever has lever arms and a lever handle. The lever arms extend from the side walls of the housing and the lever handle extends between the lever arms. A wire guide is positioned on the lever. The lever is rotatable between a pre-insertion position and an insertion position. When the lever is in the insertion position, the wire guide engages the wires which extend from the housing to direct the wires to a designated position.

A verification system for detecting a connector position assurance (CPA) device's closure relative to a corresponding housing, The verification system includes a connector position assurance (CPA) device having a first visible or visual surface; a housing having a second visible or visual surface; and a scan system that scans the first visible or visual surface of said CPA device and said second visible or visual surface of the housing. The the scan system detects whether the CPA device is in full-lock position relative to the housing depending on whether the scan system detects whether the first and second visible or visual surfaces are separated from each other or joined together. Also, a verification method for detecting a CPA device's closure relative to the housing, which includes a step of detecting whether the CPA device is in a pre-lock position or in a full-lock position relative to the housing based on whether the scan system detects whether the first and second visible or visual surfaces are separated from each other or joined together. The scan system or scanning step also detects whether the CPA device is in a pre-lock position or in a full-lock position relative to the housing based on whether the scan system or scanning step detects that a predetermined percentage of a predetermined size or shape has been formed by at least one of a first medium on the CPA device and a second medium on the housing is within a scan window.

A verification system or method for detecting whether a CPA device is in a pre-lock position or in a full-lock position relative to the housing based on a scan system's detection that a portion of a predetermined barcode or QR code on the CPA device and another portion of the predetermined barcode or QR code are separated from each other or joined together to form the predetermined barcode or QR code. The CPA device is fully engaged or in full-lock position or status with the housing when the scan system has recognized or determined that the portion of the predetermined barcode or QR code on the CPA device and the another portion of the predetermined barcode or QR code on the housing within a scan window are joined together to form the complete or full predetermined barcode or QR code.

A vehicle electrical connector includes an outer shell, an inner shell, and a conductive assembly. The outer shell includes a groove and assembling channels. The assembling channel extends from an opening on an outer side of the groove toward an inner tubular wall surface of the groove. The inner shell is in the outer shell and includes a base and a casing. The casing extends outward from one side of the base. The inner shell includes buckle blocks outside the casing. The buckle block is guided in the assembling channel through a path of the assembling channel, so that the buckle block is positioned in the assembling channel. Hence, after the inner shell is axially inserted into the outer shell and then rotated into a predetermined position, the inner shell and the outer shell can be stably held with each other.

The present disclosure provides a battery product and an assembling method of the battery product, the battery product comprises a box and a heating connector. The box comprises a mounting panel. The mounting panel has a first receptacle portion and a second receptacle portion, and the second receptacle portion and the first receptacle portion are provided opposite to each other and communicating with each other. The heating connector comprises: a first plug assembly being mounted on the first receptacle portion; and a second plug assembly being mounted on the second receptacle portion. Compared with the technology related to the background, the battery product is equivalent to directly integrating the receptacle of the heating connector on the mounting panel, which not only eliminates the manner of fixing by the bolt, but also improves the integration of the battery product, thereby improving the space utilization and energy density.

Provided are a battery holder, a power transfer device, an electric vehicle and an installation method for electric vehicle. The battery holder includes a fixing bracket, a lock mechanism and a plurality of supporting devices, the lock mechanism is fixed on the fixing bracket, the supporting device is fixed on one side of the fixing bracket facing the battery pack. The electric vehicle includes the battery holder as described above. In the present invention, the weight of the battery pack can be simultaneously distributed on the plurality of supporting devices and the lock mechanism, the force of the fixing bracket is more evenly, the force applied by the battery pack to the lock mechanism is reduced, the force concentration of the lock mechanism on the fixing bracket is prevented, the service life of lock mechanism is improved, and improve the connection strength between battery pack assembly and battery holder.
