The present disclosure relates to a kind of laminated, photovoltaic module and photovoltaic system, the laminated includes: cell string, the upper and lower surfaces of cell string are sealed by transparent first encapsulation adhesive film, the outer periphery ring of first encapsulation adhesive film is equipped with second encapsulation adhesive film, the interface of first encapsulation adhesive film and second encapsulation adhesive film exists at the joint, the width L2 of interface satisfies: 0.5mm < L2.Therefore, the contact quality of the interface of first encapsulation adhesive film and second encapsulation adhesive film can be improved, the risk of bubble defect at the interface of first encapsulation adhesive film and second encapsulation adhesive film is reduced, the sealing property, power generation efficiency and the stability of structure of laminated are improved.

This utility model belongs to the technical field of male and female connectors, specifically relating to a high-strength snap-fit ​​male and female connector, including a male connector and a female connector. The male connector includes a first rubber core and a first metal plate, and the female connector includes a second rubber core and a second metal plate. After the male connector is inserted into the female connector, the first metal plate and the second metal plate engage with each other. The surfaces of the first and second rubber cores are each provided with four grooves, and the first and second metal plates are all disposed in the grooves. The first and second metal plates are both concave in the front and convex in the back. This device increases the contact area between the first metal plate 12 and the second metal plate 22 after engagement, enhancing the engagement and ensuring good contact while also extending the service life of the male connector and the female connector.

The utility model discloses a semiconductor structure, which comprises a plurality of active regions arranged on a substrate, a plurality of gate structures extending along a first direction and intersecting with the active regions, and dividing each active region into a middle part and two end parts. The plurality of bit line structures extend across the active region in the second direction and are electrically connected with the middle part of the active region. The bit line structures include a first bit line structure on the outer side and a second bit line structure on the inner side. The first plug structures and the second plug structures are alternately arranged on the outer side of the first bit line structure at intervals in the second direction, the bottoms of the first plug structures are lower than the bottoms of the second plug structures, the contact area between the bottoms of the first plug structures and the ends of the active region is large, and the electric connection quality can be improved.

This invention discloses a downhole insertion-type long-lasting isolating production combination tool, relating to the field of long-lasting isolator technology. It includes a central tube, with a fixing block fixed at an equal angle on the outer side of the upper end of the central tube. The fixing block is fixed to a connector, and a sealing mechanism for sealing the production pipe is slidably connected to the inner side of the connector. This downhole insertion-type long-lasting isolating production combination tool employs a cleaning mechanism that converts axial gravity into rotational torque through a combination of spirally distributed rollers. When the tool is lowered, the arc-shaped panel adheres tightly to the pipe wall under the thrust of the airbag. The friction between the spiral rollers (30°-60° rise angle) and the pipe wall generates a tangential component force that causes the entire rotating assembly (ring, arc-shaped panel, scraper) to rotate around the central tube. The scraper rotates accordingly, scraping away the circumferential attachments. This process continues throughout the entire lowering stroke, achieving a pretreatment effect on the well wall of the sealing section, significantly improving the contact quality and working life of the subsequent sealing sleeve and metal slips.
