Abstract: A connector assembly includes a housing having a housing base, a housing body protruding from the housing base, and a first housing protrusion provided inside the housing body. A protection part includes a protection base facing the housing base, a protection body protruding from the protection base, and a first protection arm extending from the protection body for engaging with the first housing protrusion. An insertion part of the assembly includes an insertion body for inserting inside of the protection part, and a first insertion protrusion protruding from the insertion body to interfere with the first protection arm. The first insertion protrusion deforms the first protection arm and causes the first protection arm to disengage from the first housing protrusion while the insertion body is inserted inside of the protection part.

Abstract: Disclosed is a method for analyzing a sulfide-based solid electrolyte using computer simulation including connecting, by a user, to a client accessible to a server, inputting information of a sulfide-based solid electrolyte to be analyzed to the client, transmitting, by the client, the information to the server, implementing, by the server, generation of a three-dimensional structure in which anion clusters and lithium ions are disposed, based on the transmitted information, feeding back, by the server, an implementation result to the client, and displaying, by the client, the feedback result. In addition, properties of sulfide-based solid electrolytes, which cannot be observed by experimentation, can be analyzed based on lithium, ion conductivity.

Abstract: A connector includes a connector housing and a cable assembly configured to be inserted into the connector housing and fixed to the connector housing. The cable assembly has a cable, a terminal portion configured to electrically connect the cable to an external terminal, and a sealing assembly pressed into an outer sheath of the cable and forming a watertight seal with the cable. The sealing assembly is disposed separately from the terminal portion. The cable assembly is elastically connected to a first fastening portion of the connector housing.

Abstract: A connector assembly comprises a housing assembly including a housing shell and a center pin disposed on an inner side of the housing shell, and a head assembly including a head shell detachable from the housing shell, a head body fixed to an inner side of the head shell, and a socket mounted on the head body. The socket includes at least four contact members disposed around a central axis of the head body in a circumferential direction. Each of the contact members has a shape bent toward the central axis of the head body.

Abstract: A metal/support catalyst for conversion of carbon dioxide to methane contains a metal including a transition metal and a support containing a perovskite-type oxide, on which the metal is supported. The metal/support catalyst for conversion of carbon dioxide to methane is capable of increasing the catalytic activity of the Sabatier reaction by promoting the formation of hydroxide ions and helping the production of formate, which is a reaction intermediate in the conversion of carbon dioxide to methane, without using a precious metal. In addition, it is capable of conducting the reaction stably for a long period of time.

Abstract: A method for preparing a sulfide-based solid electrolyte which is stable upon exposure to the air is provided. Specifically, a stabilization layer is formed on the surface of a sulfide-based solid electrolyte particle through treatment with a reactive gas. The sulfide-based solid electrolyte with superior air stability can be obtained because oxidation or reduction reactions with water, etc. in the air occur on the stabilization layer rather than on the sulfide-based solid electrolyte particle.
