Abstract: The length of a waterproof and dustproof connector can be reduced to decrease its occupation area so as to secure the occupied area of the circuit board for electronic equipment and so as to design the layout of the electronic equipment more freely and so as to downsize the electronic equipment. The connector for electronic equipment includes an approximately cylindrical housing 2, a support 21 provided in the form of a wall in the housing 2, a contact terminal 3 and a power terminal 4 supported by the support 21, a shell 5 mounted inside the housing 2, and a seal 6 provided along the outer circumference adjacent to the end on the connection terminal inserting side of the housing 2. Preferably, the seal 6 is welded to the housing 2 and made of a resin softer than the resin of the housing 2.

Abstract: A waterproof connection apparatus for electronic equipment includes: an approximately tubular outer case; a supporting portion accommodated in a wall form on a deep side of the outer case; a contact terminal supported by the supporting portion and introduced in the outer case; and a circumferential sealing portion provided at a position between the outer case and the supporting portion to seal a space between the outer case and the supporting portion. The sealing portion formed of an elastic material is provided so as to protrude outward from a portion of an outer circumferential surface of the supporting portion and the sealing portion is pressure-contacted to an inner surface of the outer case in a circumferential form in a state of press-fitting the protruding portion. In this way, it is possible to reliably prevent water from entering into the deep side of the outer case and to decrease the length.

Abstract: A waterproof connector provided herein is capable of reducing an area taken up by the connector while ensuring waterproof performance, achieving layout design of electronic equipment more freely, and contributing to size reduction of the electronic equipment. This waterproof connector is also capable of increasing the strength and durability of a shell dramatically.

Preferably, the shell (2) is provided with a non-through recess (26) formed so as to bulge outward. The non-through recess (26) allows engagement of a hook of a plug.

Abstract: A multipole jack includes a main body and a case. The substantially cylindrical main body includes terminal bases which make contact with electrodes of a multipole plug. Connecting ends of the terminal bases are led out from the main body. The main body is attached to the substantially bottomed cylindrical resin case through an opening of the case. Inner ends of extension terminals which protrude from side walls of the case and are insert-molded are electrically connected to the connecting ends of the corresponding terminal bases. Therefore, it is possible to further increase a battery size of an electronic device in which a multipole jack is provided by decreasing an entire length of the multipole jack, and to meet the demand for reducing the size of a multipole jack by reducing the length of terminals.

A middle section of at least one of the insulating parts is provided with an insulating material such as an electrodeposition coating part or an insulating tube separate from the insulating resin for insert molding. The separate insulating material is provided so as to cover a given area of the outer circumference of the bar electrode or a given area of an outer circumference of the tubular electrode.

Abstract: A multipole jack includes a main body and a case. The substantially cylindrical main body includes terminal bases which make contact with electrodes of a multipole plug. Connecting ends of the terminal bases are led out from the main body. The main body is attached to the substantially bottomed cylindrical resin case through an opening of the case. Inner ends of extension terminals which protrude from side walls of the case and are insert-molded are electrically connected to the connecting ends of the corresponding terminal bases. Therefore, it is possible to further increase a battery size of an electronic device in which a multipole jack is provided by decreasing an entire length of the multipole jack, and to meet the demand for reducing the size of a multipole jack by reducing the length of terminals.

Abstract: A multiconductor plug (10) has exposed electrodes (11a through 11e) on a shaft portion (14) and an electrode (11f) located at an annular flat portion of a flange portion (15) perpendicular to an axial direction. A multiconductor jack (20) has a casing (21) forming a space capable of being occupied by the shaft portion (14) of the multiconductor plug (10), electrically conductive terminals (23a through 23e) that come into electrically conductive contact with the electrodes (11a through 11e) of the shaft portion (14) of the multiconductor plug (10), and an electrically conductive terminal (23f) having a contacting portion (23f1) for making electrically conductive contact with the flat electrode (11f) perpendicular to the axial direction and an elastic portion (23f3) that extends in the axial direction. The contacting portion (23f1) of the electrically conductive terminal (23f) presses against the electrode (11f) as a result of elastic forces parallel to the axial direction.
