  • Patent number: 8698043
    Abstract: A grip member with an electric heater, in which the surface of a core body when a heater is installed is flat. A metal conductive plate, such as a SUS plate with a thickness of about 30 ?m formed in a belt-like shape, is spirally embedded along a flat groove section provided in a core body, the surface of the core body is made flat, and the metal conductive plate is fixed at both ends to the core body. An electric current is passed through the metal conductive plate to cause it to generate heat.

  • Patent number: 7927138
    Abstract: An electrical connector that is reduced in size by appropriately combining connection terminals and a connector housing. Terminal insertion openings (15) for terminal accommodating holes (14) are formed in the rear face of the connector housing (11). The terminal insertion openings (15) each have an elliptic cross-section, and the ellipses are arranged so as to be aligned in a specific direction. Oblong sections of connection sections, having a narrow width, of the connection terminals are inserted into the terminal accommodating holes (14), along the terminal insertion openings (15). The connection terminals are engaged with elastic case lances and connection sections provided in the terminal receiving holes and are fixed in position.

  • Patent number: 7883361
    Abstract: A connection member of simple structure having a high reliability and capable of performing electric cable branching is provided. Connection portions of a plurality of electric cable terminals having an electric cable are respectively inserted into an electric cable terminal insertion hole of a holding body. Cylindrical contact points of the connection portions are aligned in a pin terminal insertion hole and a pin terminal is inserted into the pin terminal insertion hole. The pin terminal is successively inserted into the cylindrical contact points of the electric cable terminals arranged in parallel in the pin terminal insertion hole so that the pin terminal is electrically connected to the plurality of connection portions and the connection portions are short-circuited with one another.

  • Publication number: 20090221190
    Abstract: An electric connector housing that is, even though small in size, capable of fixing a connection terminal with large engagement force. An upper cover (22) is placed on a holder (21) where a connection terminal (11) is fixed, and the holder (21) and the upper cover (22) are connected by a locking mechanism. In this state, the holder (21) and the upper cover (22) firmly prevent the connection terminal (11) from moving in a front-rear direction and a top-bottom direction. The connector housing cooperates with a mating connector to cause connector terminals to be fitted together, and functions as a connector.

  • Patent number: 6699079
    Abstract: A rear holder 4 is inserted into a housing 3 from a rear end surface 24 at a provisional locking position in which the rear holder 4 is inserted into the housing 3 halfway and an insertion of connecting terminals is allowed, as well as at a sufficiently inserted complete locking position at which the inserted connecting terminals are locked. Within the housing 3, there are formed two rows of terminal accommodating holes 28 each accommodating respective connecting terminals. The rear holder 4 is formed in a substantially plate-like shape and includes a main body 41 which is inserted into slits 29 of the housing 3 and locking arms 45 which are inserted into respective terminal accommodating holes 28. A width of a locking arm 45 is slightly smaller than that of a terminal accommodating hole 28. Windows 37 are formed in the outer wall 21 of the housing 3 such that the terminal accommodating holes 28 are communicated with external through the windows 37.
