The invention belongs to the technical field of composite material preparation, and particularly relates to a tungsten infiltrated copper composite material and a preparation method thereof. According to the invention, through a multi-scale through pore network formed by'prefabricated material construction ', molten copper liquid can be rapidly filled along a large pore channel and fully permeates into the tail end of a small pore, so that the defect of'black core' generated by closed pores is thoroughly avoided. According to the prepared composite material, the tungsten phase and the copper phase respectively form a stable and communicated three-dimensional network, so that the unification of high conductivity (greater than or equal to 60% IACS), high strength and toughness (hardness greater than or equal to 100 HB) and excellent arc ablation resistance is fundamentally and synergistically realized, and the long-standing limitation of'impossible performance triangle 'is effectively broken through. And the process is high in integration level, green and remarkable in strengthening effect, and process simplification, environmental protection strengthening and performance improvement are achieved at one stroke. The advantages of raw materials and process cost are outstanding, the industrialization prospect is wide, and the relationship among high performance, designability and mass productivity is perfectly balanced.

The application provides an external stroke monitoring device, belonging to the technical field of shield machines; the stroke monitoring device comprises a first connecting main body, a second connecting main body, a movable piece and a detection element; the first connecting main body and the second connecting main body are mutually sleeved to form a connecting assembly; one end of the connecting assembly is hingedly connected with a sliding frame, and the other end of the connecting assembly is connected with other static components of an anchor excavator; the movable piece is installed on the first connecting main body or the second connecting main body, and the movable piece is fixedly connected with a detection end of the detection element. The application provides an external stroke monitoring device which is convenient to disassemble and install, has a simple structure, is convenient to disassemble and install, and is easy to maintain daily; when the stroke monitoring device has a problem, the stroke monitoring device can also be quickly and effectively maintained, thereby saving the maintenance time of the device and improving the use efficiency of the equipment.

This invention relates to the field of battery technology, specifically to a battery. The battery includes a casing and an electrode assembly, the electrode assembly being located within a receiving space formed by the casing. The casing includes a first through-hole, and the battery further includes a connecting mechanism connected to a first tab assembly, the connecting mechanism passing through the first through-hole. The connecting mechanism includes a conductive element and an insulating element, the conductive element being connected to the first tab assembly, and the insulating element being located between the casing and the conductive element. At least one of the interfaces between the conductive element and the insulating element and between the insulating element and the casing forms a bonding region. The bonding region includes a first surface of the conductive element facing the insulating element and / or a second surface of the casing facing the insulating element, the first surface and / or the second surface including a plurality of recesses, the orthographic projection of the insulating element covering the recesses, and the insulating element including protrusions embedded in the recesses. The battery of this invention is applicable to batteries of various thicknesses and can improve the sealing performance and connection strength of the connecting mechanism.
