Abstract: In a coaxial connector, a casing, which is connected to an outer conductor of a horizontally-extending coaxial cable, and holds an insulator in surrounding relation thereto, comprises an inner casing and an outer casing connected together through engagement projections and so on. The inner casing of an integral construction includes a vertically-extending external terminal portion of a tubular shape having a slit formed in its front end, insulator holder portions extending upwardly respectively from opposite sides of an upper end of the external terminal portion, a connecting plate portion extending from a rear upper end of the external terminal portion, and outer conductor clamping piece portions extending upwardly respectively from opposite side edges of the connecting plate portion. The outer casing includes an upper plate portion closing an upper side of the insulator holder portions. The coaxial connector provides a good assembling efficiency and good quality stability.

Abstract: In a surface-mounted type coaxial connector where a coaxial cable 10 and a substrate 12 are electrically connected by fitting the plug 44 connected to the coaxial cable 10 into the receptacle 80 surface-mounted on the substrate 12, a central contact 51 of a plug 44 is made from a male contact and a central contact 82 of the receptacle 80 is made from a female contact reducing thus the height Hp of a shell 46 of the plug 44. As necessity arises, the electrical connection of the central conductor 18 of the coaxial cable 10 is positioned opposite the attaching portion of the plug 44 with the coaxial cable 10 as seen from the central contact 51, reducing thus the length Lp of the shield cover 45 of the plug 44.
