A terminal module (10) has a metal case (20) with a ceiling wall (21), a bottom wall (51) facing the ceiling wall (21), opposed side walls (23) extending from the ceiling wall (21) toward the bottom wall (51) and retaining pieces (24). A coil spring (40) is sandwiched between the ceiling wall (21) and the bottom wall (51). The retaining pieces (24) face each other in a direction perpendicular to a facing direction of the side walls (23) and project toward the bottom wall (51) from the periphery of the ceiling wall (21). The side walls (23) and the retaining pieces (24) are disposed alternately on the periphery of the ceiling wall (21). A spring receiving portion (26) formed by the ceiling wall (21), the side walls (23) and the retaining pieces (24) receives an end part of the coil spring (40) on the side of the ceiling wall (21).

The present invention relates to a test socket having a thin structure that can reduce durability degradation of a contact itself, have excellent electrical characteristics in processing high-speed signals, and can extend a service life thereof, and relates to spring contacts suitable thereto. The test socket according to the present invention includes: a plurality of spring contacts (100) each of which includes an upper contact pin (110) and a lower contact pin (120) that are assembled cross each other, and a spring (130) supporting the upper and lower contact pins (110 and 120); a main plate (1110) having a plurality of accommodating holes (1111) in which the respective spring contacts (100) are accommodated, with first openings (1113); and a film plate (1120) provided on a lower portion of the main plate (1110), and having second openings (1121).

A receptacle connector includes a metal housing configured to prevent backwards insertion of a plug. The receptacle connector has walls bounding an assembly space with an insulative body therein. One wall is distant from an exterior surface of the insulative body to form an abutting groove between the metal housing and the insulative body. The abutting groove is configured to receive an abutting wall of the plug connector. The insulative body includes mating interface configured to receive a terminal portion of a plug connector. A wall of the metal housing opposite the abutting groove is adjacent a surface of the insulative body has a projection. If a user attempts to insert the plug with the terminal portion backwards, the projection interferes with the abutting wall, preventing backwards insertion of the terminal portion of the plug into the mating interface.

A male and female power terminal assembly including a male terminal having a male contact portion including an outer contact surface and an inner surface, and a female terminal having a female contact portion including a sleeve and a finger made of an electrically conductive material. The outer contact surface is electrically connected to an inner surface of the sleeve. Further, the male terminal includes a connecting member made of an electrically conductive material which is placed inside a cylindrical hollow portion of the male terminal, and which interconnects the finger with the inner surface.

A lamp socket for a cooking appliance lamp, the lamp socket including a socket body; at least one supply contact configured to connect to a connection conductor configured to supply electrical voltage electrical voltage to the cooking appliance lamp; at least one socket contact electrically connected with the at least one supply contact and connected to an illuminant socket of the cooking appliance lamp; a contact cavity formed by the socket body wherein the at least one socket contact is arranged in the socket cavity; a fastener that fastens the at least one supply contact at the socket body, wherein the fastener is integrally provided in one piece with the at least one supply contact or bonded to the supply contact.

A lamp socket for a cooking appliance light, the lamp socket including a socket body; a base receiver configured to receive a lamp base of a lamp and formed at a top side of the socket body; connection contacts for external connection conductors of a voltage supply, the connection contacts arranged at a bottom side of the socket body; an attachment ring configured to retain the lamp base in the base receiver; two retaining arms integrally formed at the attachment ring; two spring arms respectively arranged at the two retaining arms and forming a receiving gap for the lamp base between each other and respectively including a free spring arm end and a connected spring arm end respectively connected at each of the two retaining arms, wherein the two spring arms are arranged in the base receiver.

A surgical stapling instrument includes a body portion and a tool assembly extending from the body portion. The tool assembly includes a jaw member, and a first connector assembly disposed within the jaw member. The first connector assembly includes a first connector housing and first and second connector members extending from the first connector housing. The surgical stapling instrument further includes a cartridge assembly selective receivable within the jaw member. The cartridge assembly includes a second connector assembly configured for electrical connection with the first connector assembly. The second connector assembly includes a second connector housing and first and second contact members disposed within the second connector housing. The first and second connector members of the first connector assembly are configured to engage the respective first and second contact members of the second connector housing when the cartridge assembly is received within the jaw member of the tool assembly.

A male terminal fitting is provided with a base wall extending in a front-rear direction, and a plate-like tab portion extending forward from a front end part of the base wall.
