Abstract: This disclosure relates to a connector comprising a first RF contact; a second RF contact spaced apart from the first RF contact in a first axis direction; an insulation part; and a cover shell, wherein the first RF contact includes a (1-1)th RF linker member for connecting with an RF contact of the other connector; a (1-2)th RF linker member spaced apart from the (1-1)th RF linker member on the basis of a second axis direction perpendicular to the first; and a first RF linker member arranged between the (1-1)th RF linker member and the (1-2)th RF linker member on the basis of the second axis direction, the insulation part includes a first RF inspection window arranged between the (1-1)th RF linker member and the (1-2)th RF linker member on the basis of the second axis direction, and the first RF linker member is exposed through the first RF inspection window.

Abstract: Disclosed are novel compounds of Chemical Formula 1, optical isomers of the compounds, and pharmaceutically acceptable salts of the compounds or the optical isomers. The compounds, isomers, and salts exhibit excellent activity as GLP-1 receptor agonists. In particular, they, as GLP-1 receptor agonists, exhibit excellent glucose tolerance, thus having a great potential to be used as therapeutic agents for metabolic diseases. Moreover, they exhibit excellent pharmacological safety for cardiovascular systems.

Abstract: A waterproof receptacle connector includes: a plurality of contacts, a support plate for partially covering and protecting the contacts, an insulator on which the contacts are installed; and a shell for containing the insulator on which the contacts are installed, wherein the shell has upper, lower, left, and right surfaces processed with no holes or pores, except for a front surface portion through which a plug connector is inserted and a rear surface portion through which the insulator is inserted, and, after the insulator is inserted through the rear surface portion of the shell, an interruption portion may be formed on the rear surface.

Abstract: A multi-type receptacle connector includes a receptacle insulator, main receptacle contacts arranged at the receptacle insulator to provide an electric contact point corresponding to a universal plug connector, sub receptacle contacts additionally installed at both sides of the main receptacle contacts to give an additional contact point, and a receptacle shell surrounding at least a part of the receptacle insulator, wherein the sub receptacle contacts are arranged at the same height as the main receptacle contacts and disposed at a relatively inner side in the insertion direction of a plug connector in comparison to the main receptacle contacts.
