Description

Technical Field

[0001] The present invention relates to an auxiliary device in an electrical component for facilitating the connection or disconnection of connection parts, and in particular to a connector base, a connector and a battery pack. Background Art

[0002] With people's demand for vehicles and requirements for environmental protection, a large number of electric and hybrid vehicles have been developed and widely used in commercial fields such as mining and road transportation. The application markets of vehicles are segmented, and the vibration conditions of vehicles in different application markets are also different. For example, the road surface flatness of mining vehicles is poor when driving, and the vibration conditions are relatively severe, while the road surface of highway vehicles such as buses, heavy trucks, card clearance and sanitation vehicles is relatively flat, and the vibration conditions are relatively loose. No matter which market segment the electric vehicles are in, they will inevitably be subject to vibration and impact during driving, causing the battery pack of the vehicle to shift, loosen, or even wear and tear, resulting in failure of the electrical connection.

[0003] For road vehicles with relatively loose vibration conditions, a plug-in handle connector is often installed on the battery to avoid the loosening of the battery due to vibration or impact during vehicle driving. For example, the Chinese utility model patent with authorization announcement number CN218828190U and authorization announcement date 2023.04.07 discloses a secondary locking mechanism, a high-voltage connector and a connector assembly, the connector assembly includes a socket and a connector plugged and unplugged with the socket, ear columns are provided on both sides of the socket, the connector includes a connector housing and a power-assisted pull seat, the power-assisted pull seat includes a pull seat body and two power-assisted arms, the two power-assisted arms are respectively connected to the two ends of the pull seat body and each is provided with a socket tightening structure that cooperates with the ear columns on both sides of the socket, when the socket tightening structure on the power-assisted arm is cooperated with the ear column, the power-assisted pull seat can be flipped, and at the same time, each of the two power-assisted arms is provided with a connecting shaft, and the two power-assisted arms are rotatably installed on the connector housing through their respective connecting shafts, and a plug is installed on the connector housing, the plug is used to lock the pull seat body, thereby limiting the rotation of the power-assisted pull rod, and ensuring the tightening and connection between the connector and the socket.

[0026] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0027] Both the plug-in lock bolt connector and the plug-in handle connector are used as connection devices for the battery pack of an electric vehicle, and are respectively suitable for reducing the relative movement of the battery pack caused by vibration under relatively severe and relatively loose vibration conditions. The plug-in lock bolt connector and the plug-in handle connector are two types of connectors, and their installation methods with the battery pack are also different, and the corresponding types of battery packs are also different. In order to improve the uniformity of use, the compatibility of the lock bolt connector and the handle connector is achieved by connecting the two connectors on the same connector base. Based on the above inventive concept, the present invention proposes a connector base, a connector, and a battery pack, which can achieve the common use of the bases of the lock bolt connector and the handle connector, saving a connector base, and can flexibly select the lock bolt plug or the handle plug according to the severity of the vibration condition, so as to achieve the optimal combination of electrical connection reliability and operational convenience.

[0028] Embodiments of the connector base of the present invention:

[0029] See also Figures 1 to 3 As a basic embodiment of the present invention, the connector base includes a base body 1, which is used to be fixed to the battery pack. The base body 1 is provided with a plug-in portion 2, and the plug-in portion 2 is symmetrically connected to two ear columns 3, which are located on two opposite outer sides of the plug-in portion 2, and the ear columns 3 are used to be connected to the handle of the handle plug 4. Two raised seats 5 are also fixedly provided on the base body 1, and the two raised seats 5 are located on both sides of the plug-in portion 2 and are arranged corresponding to the two ear columns 3, and are arranged at intervals with the plug-in portion 2. A screw hole 6 is opened on the raised seat 5, and the screw hole 6 is used to align with the positioning hole 11 of the lock bolt plug 8 and to screw in the bolt 7 so that the lock bolt plug 8 is fixedly connected to the raised seat 5, and the interval between the raised seat 5 and the plug-in portion 2 can provide the space required for the lock bolt plug 8 to be plugged into the plug-in portion 2, and at the same time can improve the connection strength between the lock bolt plug 8 and the raised seat 5. When in use, the plug The connecting portion 2 is plugged into one of the handle plug 4 or the lock bolt plug 8, so that the base body 1 and the handle plug 4 or the lock bolt plug 8 form a good electrical connection, and the ear column 3 and the screw hole 6 are simultaneously provided on the base body 1, so that the same base body 1 can be connected with the handle plug 4 and the lock bolt plug 8 respectively, so as to realize the compatibility of the connector base with the handle plug 4 and the lock bolt plug 8, improve the versatility of the connector base, and the connector base can be suitable for any vibration working conditions. When encountering more severe vibration working conditions, the lock bolt plug 8 is plugged into the base body 1, and the lock bolt plug 8 and the base body 1 are fixed by bolts 7 to meet the use requirements. If encountering more relaxed vibration working conditions, the handle plug 4 is plugged into the base body 1, and the handle plug 4 and the base body 1 are connected by the ear column 3 to meet the use requirements.

[0030] When the ear column 3 is connected to the handle plug 4, the screw hole 6 is idle and standby. The specific connection method between the ear column 3 and the handle plug 4 is the existing technology and will not be repeated here. The handle plug 4 can be used under relatively loose vibration conditions, and the handle plug 4 is easy to plug and unplug with the base body 1, and the installation is convenient and quick, which can improve the installation efficiency of the vehicle connector; when the screw hole 6 is connected to the locking bolt plug 8 through the bolt 7, the ear column 3 is idle and standby.
