A clamp spring type self-locking cable cover on an electric connector comprises a connecting nut, clamp pins, clamp springs, a clamp ring and a cable cover element. The clamp springs are fixed into clamp spring grooves of the connecting nut via the clamp pins, and the cable cover element is mounted in a clamp ring groove of the connecting nut via the clamp ring. The clamp spring type self-locking cable cover has the advantages of high looseness prevention reliability and small occupied structural space.

The invention provides an electric wrench rack with a water discharging groove and applicable to hot-line work and relates to an electric wrench sleeve assembling and disassembling device. An electric wrench needs to be matched with bolts with different diameters so that a sleeve needs to be frequently replaced; and the sleeve commonly can be disassembled by two people so that the potential safety hazard is great and the efficiency is low. The electric wrench rack comprises a sleeve assembling and disassembling device, a wrench placing rack and a fixed rack, wherein the sleeve assembling and disassembling device comprises a disassembling plate, a sleeve box and a rear plate; the disassembling plate is provided with a plurality of U-shaped clamping grooves; openings of the clamping grooves are chamfered or rounded; the sleeve box is provided with a plurality of sleeve containing cavities; the clamping grooves are communicated with the sleeve containing cavities; a notch is arranged between the disassembling plate and the sleeve box; the fixed rack is provided with an n-shaped slot; a positioning column is arranged on the inner wall of the slot; the positioning column is provided with a screw hole for penetrating a bolt which is abutted against a bucket arm curb frame; a counter bore is formed on the rear face of the fixed rack; an insulating layer covers the surface of the fixed rack; and a water discharging groove is opened on a bottom plate of the sleeve box. According to the technical scheme disclosed by the invention, the assembling and disassembling efficiency of a sleeve is high; and the electric wrench rack is reliable, is good in working safety and is good in insulation.

The invention discloses a layered message distribution method, electronic equipment and media. The method includes the steps of: acquiring a target identification code corresponding to a target message; establishing a target distribution system with a network cascade structure; based on the target distribution system, The target identification code is sent to the client at the level of the target distribution system one by one. The target distribution system includes broadcast center modules of multiple distribution levels and a configuration management module connected to the broadcast center module of the highest distribution level, wherein, in multiple distribution levels In, the target identification code is sent one by one to multiple broadcast center modules and / or configuration management modules in the next distribution level through each broadcast center module in any distribution level; the target identification code is sent through each broadcast center module in the highest distribution level A configuration management module sends a plurality of clients one by one; the present invention can realize sub-second sending of messages for more than tens of millions of users, shorten sending time and improve sending efficiency.

The present invention provides a distributed-based wireless charging method and system. The system includes a primary device and a secondary device, and the secondary device includes several independent and distributed sub-battery packs installed in different positions of the electric vehicle. , and independent secondary receiving coils and battery management systems connected to the sub-battery packs at different positions, each independent secondary receiving coil is matched with each primary transmitting coil of the primary device, and each battery management system The systems are all connected to the secondary side control unit; the charging control and the balanced charging management of the battery are performed through the primary / secondary side control unit. The system can realize the balanced management and cooperative work of each sub-battery pack in the vehicle, reduce the electromagnetic radiation intensity during the charging process, and improve the safety of charging.

The invention discloses a message distribution method based on mesh cascading, electronic equipment and media. The method includes the steps of: acquiring a target identification code corresponding to a target message; establishing a target distribution system, and the target distribution system includes: a plurality of The broadcast center module at the distribution level and the configuration management module correspondingly connected to the broadcast center module at the highest distribution level; obtain the target time list, traverse the target time list and when any time value is not less than the preset time threshold, distribute the target The system is divided into a first unit and a second unit; based on the first unit and the second unit, the target identification code is sent to the client at the distribution level one by one; The amount of messages can be sent at sub-second level, which shortens the sending time and improves the sending efficiency.

The invention relates to a vehicle instrument device with a charging device. A vehicle is provided with a vehicle frame unit. A head pipe of the vehicle frame unit is provided with a steering mechanism, and the position, facing the front portion of a vehicle body, of the head pipe at least is provided with an instrument device fixing base which is connected with the vehicle instrument device through a supporting frame. The vehicle instrument device is characterized in that a containing part is formed in a base of the instrument device, and the charging device is installed inside the containing part of the base; when a driver wants to use the charging device, the driver can use the charging device very conveniently without any obstruction, and meanwhile the charging device has a good dustproof property and a good water draining property.
