The invention discloses a detection device and method for a LED chip and a device. The device comprises a blue film or a device substrate clamping jig, an annular array testing electrode, and a power supply and electrical parameter acquisition system. The annular array testing electrode is roller-shaped in appearance and provided with multiple groups of positive and negative test probes. When detection is carried out, the detection device is driven through a synchronous pulley to enable the positive and negative test probes to be exactly contacted with a positive electrode and a negative electrode of an LED chip to be tested or exactly contacted with a positive electrode and a negative electrode of a device, sweep currents are connected into a list of probes contacted with a substrate right now through a power supply in sequence, electrical parameters of the device are collected at the same time, and the synchronous pulley drives the device to roll to the next adjacent list of probes after collection is completed, and the next list of LED chips or devices are tested. The technical method is extremely high in efficiency, detection efficiency can be improved by 6-10 times compared with a traditional detection method, the detection device is applied to the LED industry, detection efficiency of LED products is greatly improved, equipment loss is reduced, product cost competitive advantages are promoted, and the detection device has good industrialization application prospects.

A motor for vacuum cleaner is composed of casing, end covers, stator, rotor, shaft, blade wheel and its cover, stator terminal, and electric brush and its terminals for contacting with stator terminal. Its feature is that said electric brush has 3 contact parts with stator terminal, so having high contact reliability.

The invention discloses a speed bump for municipal engineering. The speed bump comprises a shaft body base body and a shaft body base split body, and is of a square cavity structure, the shaft body base body and the shaft body base split body are symmetrically distributed and have the same internal structure, a telescopic shaft body is fixed to the center of the bottom of the shaft body base body,a reset spring sleeves the outer side of the telescopic shaft body, a shaft cap sleeves the top of the telescopic shaft body, a supporting pillar is arranged at the top of the shaft cap, and a speedbump body is connected to the top of the supporting pillar. In the running process of a vehicle which runs at a normal speed, the hindering effect of the speed bump on the vehicle cannot occur, and trouble of a driver in normal driving is reduced; a vehicle which overspeeds cannot be hindered at the first speed bump but is hindered from running by the second speed bump, inconvenience is brought topassengers and a driver in the vehicle, and the driver is effectively reminded to abide by the traffic rule of speed limiting.

An excimer lamp is provided, which can suppress deterioration caused by oxidation of power supply wires for supplying electricity to the excimer lamp and the connection portion for connecting the power supply wires to the electrodes, improve reliability, and prolong life thereof. The excimer lamp of the invention includes an electrode provided outside the capacitor, gas for discharging is enclosed inside the discharging capacitor, medium is provided between the electrode and another electrode in the same pair with the electrode, conductive wires for supplying electricity between the electrodes are connected to the electrode and the other electrode, and electricity is supplied to the gas for discharging through the conductive wire, the electrode, and the medium. In the structure, a space connected to one terminal of the discharging capacitor and divided by at least five faces is provided, the space is isolated from the capacitor by an isolation wall, and a connection portion electrically connected to the electrode is formed outside the space. The conductive wires are connected to the connection portion through soldering tin.

The invention relates to the technical field of electric connection, and especially relates to a data line and a preparation method of the data line. The data line comprises a first electric connection structure and a second electric connection structure. The second electric connection structure and the first electric connection structure are sleeved and electrically connected, and the first electric connection structure and the second electric connection structure are rotatably connected. The invention provides a preparation method of a data line. The data line and the preparation method of the data line provided by the invention have the advantages that the joint is not easy to lose and can rotate at any angle.

The invention provides a storage device for information processing, and relates to the technical field of storage devices. The storage device for information processing comprises a shell, wherein an outlet is formed in the top of the shell; an inserting opening is formed in the bottom of the outlet in the shell; a connecting base is rotationally connected to the bottom of the inserting opening; astorage area is fixedly installed at the bottom end of the connecting base; a locking device is fixedly connected to the bottom end of the storage area; and a covering device is fixedly connected to the right side of the connecting base. For the storage device for information processing, the inserting opening can only be popped up through the digital password, so that the safety of the storage device is improved and information leakage is avoided; and when the storage device is not used, the outlet can be shielded to avoid the dust entering the inserting opening so as to avoid the poor contactphenomenon of the inserting opening caused by dust falling, and the phenomenon that the inserting opening is separated from a USB interface due to collision of the shell is avoided due to the fact that the inserting opening is rotationally connected with the connecting base.

The invention discloses an automatic adjustment and fixing device for a charging port of a new energy vehicle. A spiral ring is provided, and a plurality of contact rods are arranged around the inside of the spiral ring. A fixed plate is provided at one end of the fixed cylinder, and a slide groove is provided on the side wall of the fixed plate. The spiral ring is close to the side of the fixed plate. One end is surrounded by a ratchet. When the spiral ring of the present invention rotates, it will shrink toward the inner center, and then drive the contact rod to squeeze toward the center, so that the insertion rod of the charging head can fit with the contact rod, and then the power is transmitted to the contact rod through the insertion rod of the charging head The surface, and then transmitted to the cable at one end of the fixed plate through the contact rod, has the advantages of automatically fixing the charging plug and being applicable to charging heads of various diameters.
