Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of connectors, and particularly relates to a novel power source clamping structure. BACKGROUND

[0002] Traditional low-voltage storage batteries for vehicles are mostly lead-acid batteries. A live conductor column led out of the lead-acid battery can be used to clamp an external power source when the battery has no electricity, so as to start the vehicle. In the use scenario of the traditional low-voltage storage battery for starting the vehicle, this clamping scheme is stable and reliable. However, when the low-voltage lead-acid battery is changed into a low-voltage lithium battery, because an independent battery management system is needed to monitor the working state of the low-voltage lithium battery, the function of the control system is more, the structure is more complex, and the safety protection level is also higher. The conductor column power source clamping scheme of the lead-acid battery has certain safety risks when applied to the complex low-voltage lithium battery circuit because of poor protection performance and low safety level.

[0023] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and preferred embodiments.

[0024] An embodiment of a novel power connection structure, such as... Figures 1 to 6 As shown, the device includes an insulating housing 1, a lap contact 2, and a sealing assembly. The insulating housing 1 and the lap contact 2 are integrally injection molded. The insulating housing 1 is mounted on the panel 8 to position the lap contact. The lap contact 2 has a lap end 21 for connecting to an external power source and a connecting end 22 for connecting to a wire in the internal low-voltage circuit, thereby achieving electrical contact and conduction between the external power source and the internal low-voltage circuit. Both the lap end and the connecting end extend out of the body of the insulating housing and are exposed. Preferably, the lap contact is a sheet-like structure with a 90° bend, so the lap end and the connecting end are perpendicular to each other. However, the present invention does not limit the structural form or bending angle of the lap contact. The sealing assembly includes a top cover 3, a pull cord 4, and a sealing ring 5. The sealing assembly is used only when the sealing performance of the integrally injection molded insulating housing and the lap contact cannot meet the usage requirements or when a higher level of protection is required.

[0025] In this embodiment, the insulating housing 1 has a through hole H for threading the conductor 6 in the internal low-voltage circuit. Both ends of the through hole H have uniform outer surfaces for sealing. The conductor 6 with its insulating sheath 61 partially removed passes longitudinally through the through hole H, so that the exposed portion of the conductor 6 with its insulating sheath removed makes contact with the connection end 22 of the lap contact 2. Through crimping or welding, the connection end 22 and the conductor 6's conductor core 62 are fixedly connected. See details... Figure 5 As shown in section C, this solution with a single connection terminal is the preferred option. It eliminates the need to cut the wire and requires only one connection terminal to achieve continuity between the lap joint and the internal low-voltage circuit. The preferred solution has a simple overall structure, is easy to install and operate, and fully preserves the original conductivity of the wire.

[0026] Further, the insulating shell 1 is provided with a sealing groove 51 for accommodating the sealing ring 5, and the sealing groove is located on the insulating shell covered by the insulating shell at the bottom end of the lap joint end. After the upper cover 3 is buckled on the lap joint end 21, the inner wall of the upper cover 3 will be in extrusion fit with the sealing ring 5 to realize the sealing protection of the lap joint end. After the bottom end of the upper cover touches the top end face 11 of the insulating shell 1, it is considered that the upper cover is buckled in place. The upper cover is connected with the insulating shell through a pull rope, for example, the end of the pull rope is connected with the insulating shell through a common detachable fixing member such as a buckle structure, a hook structure or a screw.

[0027] In order to realize more stable locking of the upper cover and facilitate unlocking and dismounting, the buckle structure is further provided, which comprises a locking part provided on the upper cover 3 and a locking part provided on the insulating shell. The locking part is a lock key 31 protruding on one side of the upper cover, and the locking part comprises a cantilevered elastic arm 9, which is integrally formed with the insulating shell 1. One end of the elastic arm 9 is a fixed end for fixing on the insulating shell 1, and the other end is a movable end having a movable unlocking part 91. A locking part 92 is provided on the side of the elastic arm close to the lock key, which is buckled with the lock key. The locking part 92 is located below the movable unlocking part 91. As a preferred embodiment, a guide slope 93 is provided on the elastic arm between the movable unlocking part 91 and the locking part 92, and an adaptive guide surface 311 is provided on the bottom of the lock key 31. When the upper cover 3 is buckled downward, the adaptive guide surface on the bottom of the lock key is in sliding fit with the guide slope, gradually extruding the movable end of the elastic arm to the side away from the lock key. When the lock key moves to the locking position, the elastic arm rebounds under the action of the reset force, the lock key is buckled with the locking part, and the locking part cooperates with the top end face 11 of the insulating shell 1 to form a stop fit relationship in the up-down direction of the upper cover. This structure design facilitates single-handed buckling of the upper cover 3 and realizes automatic position locking of the upper cover. When unlocking, the movable unlocking part 91 is driven to the side away from the lock key 31, so that the locking part 92 is separated from the lock key 31, and the locking part 92 is separated from the lock key 31. The locking part 92 is separated from the lock key 31. Then the upper cover 3 can be dismounted. In another embodiment, the adaptive guide surface and the guide slope can not be provided. At this time, the locking part 92 can be first moved to avoid the lock key 31 in the up-down direction, and then the upper cover 3 is locked after reaching the locking position, so that the locking part 92 is buckled with the lock key to complete the locking of the upper cover 3.

[0028] As a preferred embodiment, in order to avoid excessive driving of the movable unlocking part and cause the elastic arm to be excessively bent and broken, a limiting part 12 is further provided on the insulating shell 1, which is spaced apart from the locking part and located on the side away from the locking part on the elastic arm. The top end of the limiting part has a limiting protrusion 121 for limiting the bending distance of the elastic arm. The limiting part is preferably a plate-shaped structure integrally formed with the insulating shell, which is positioned on the insulating shell 1 through a reinforcing rib plate 122 to avoid the elastic arm pushing the limiting part.

[0029] This embodiment also provides a preferred solution for sealing the connection end. After the wire 6 passes through the through hole H and is electrically connected and fixed to the connection end 22, both ends of the through hole H and the wire 6 need to be sealed and protected, mainly to protect the connection between the wire and the connection end; the insulating sheath 61 of the wire and the insulating shell 1 are covered by heat shrink tubing 7, and the details of the connection are shown in [details omitted]. Figure 5 In the D and E zones, heat shrinking achieves effective sealing at the joint, providing an overall seal at the junction of the connection end and the conductor core. The uniform sealing surface at both ends of the through-hole in the insulating shell ensures a tight fit with the heat-shrink tubing, achieving a good and stable protective seal. It is worth noting that in other embodiments, other types of connection end sealing and protection components, such as sealing rings or sealant structures, can also be used.

[0030] Combination Figure 1 Panel 8 serves as an installation carrier within the vehicle, used for fixed connection with insulating housing 1. The bottom of the insulating housing is provided with guide posts 13, and the panel has grooves that mate with the guide posts. The guide posts and grooves work together to pre-guide the overall power connection structure. Furthermore, the bottom of the insulating housing has pre-drilled slots for mounting clips or through holes for mounting screws, allowing installation on the panel via clip connections or screw connections.

[0031] Example 2 of a novel power supply connection structure:

[0032] The difference between this embodiment and Embodiment 1 is that the overlapping contact 2 has two connecting ends, which respectively make contact with the exposed parts of the battery core 62 of the two wires 6 with the insulation sheath 61 removed from their ends. The fixed connection is achieved by crimping or welding. This solution requires cutting the wires and requires two connecting ends to achieve the overlapping function, and there is no need to set the through hole H. In addition, the insulating shell 1 also has uniform outer surfaces at both ends for sealing, which facilitates the use of heat shrink tubing to provide good sealing protection for the connection between each battery core and its corresponding wire end. The structure of the overlapping end is the same as that in Embodiment 1, and the structure of the sealing component at the overlapping end is also the same as that in Embodiment 1, which will not be described again here.

[0033] As a secondary option, the angle between the two connection ends in this embodiment can be adjusted according to the actual working conditions, thereby connecting two non-parallel intersecting wires, which is more suitable for the actual cable wiring requirements.

[0034] The above description is merely a preferred embodiment of the present invention. Any simple modifications, equivalent changes, and alterations made by those skilled in the art to the above embodiments without departing from the scope of the present invention and based on the technical essence of the present invention shall still fall within the scope of the present invention.
