The connecting device is detachably attachable to an accessory shoe device of an electronic apparatus. An engagement member is attachable to the accessory shoe device by sliding in a first direction. A holding member is fixed to the engagement member by fastening members. A connecting plug has connection terminals and is arranged at a front part in the first direction of the holding member. The fastening members are arranged at positions that are spaced apart from each other in a second direction that perpendicularly intersects with the first direction. A width of the holding member is shorter than a width of the engagement member in the second direction, and the connection terminals are arranged in an area between the positions of the fastening members.

There is provided a connector including: a housing including a cylindrical wall portion; and a hollow annular front holder attached to the cylindrical wall portion to surround an outer periphery thereof. The front holder includes: a pair of first locking portions and a pair of operating portions arranged that are arranged to face with each other in a radial direction of the front holder. The connecter is configured such that: in a state where the front holder is fitted externally on the cylindrical wall portion, the pair of first locking portions is engaged with the cylindrical wall portion; and in response to an operation of displacing the pair of operating portions to approach with each other in the radial direction, the pair of first locking portions is displaced to release an engagement between the front holder and the cylindrical wall portion.

In an embodiment a cell-monitoring connector includes a housing including a lock portion corresponding to a groove portion defined by lock recesses stacked and overlapped in the first direction, wherein the lock recesses are formed in at least one of upper portions or lower portions of terminals protruding in a second direction, the second direction intersecting the first direction toward the cell-monitoring connector from side portions of separators included in the plurality of unit cells and a connector position assurance (CPA) including a lower portion configured to be inserted into the lock portion of the housing in a third direction and to be locked in the groove portion and an upper portion extending from the lower portion in the third direction, the upper portion having a top surface having an area larger than an area of the lower portion in a direction intersecting the third direction.

A connector includes a plurality of terminal receiving chambers arranged in parallel, a plurality of first tool insertion holes, and a plurality of second tool insertion holes. Each terminal receiving chamber is separated from an adjacent terminal receiving chamber by each of side walls disposed on both sides thereof. Each second tool insertion hole is formed to a side wall located at each of ends in a parallel direction of the terminal receiving chambers. In each second tool insertion hole, a lance unlock rib and a tool pressing rib are placed. The lance unlock rib is one of a pair of lance unlock ribs provided to a lance located at each of the ends in the parallel direction of the terminal receiving chambers. The tool pressing rib is provided to a side surface of the each second tool insertion hole, and protrudes in the each second tool insertion hole.

An implantable medical device includes a cover assembly and a feedthrough assembly that couples with the cover assembly. The cover assembly receives a connector end of a lead having lead contacts, and aligns the lead contacts with pockets or apertures of the cover assembly. The feedthrough assembly may include feedthrough contacts in the form of feedthrough pins at or above a surface of a feedthrough substrate, or conductive vias on the surface of the substrate. Electrical contacts configured as leaf spring contact assemblies, torsion spring contacts, or torsion spring contact assemblies are permanently attached to the feedthrough contacts. When the cover assembly and feedthrough assembly are coupled, contact tabs of the electrical contacts are positioned in the pockets or apertures of the cover assembly. Upon complete seating of the cover assembly and feedthrough assembly, the contact tabs are compressed into contact with the lead contacts.

A waterproof connector includes a housing having a fitting portion to be fitted into a mounting hole of a mating member. A packing mounting surface is provided on an outer peripheral surface of the fitting portion. The waterproof connector further includes a first packing mounted on a rear end side of the packing mounting surface in a fitting direction of the fitting portion, a second packing mounted on a front end side of the packing mounting surface in the fitting direction of the fitting portion, and a retainer provided between the first packing and the second packing and locked to a locking portion provided on the outer peripheral surface of the fitting portion.

A connector, including a plug terminal of a plug connected to a first electric signal line and inserted in a terminal hole of a plug body, a socket terminal of a socket connected to a second electric signal line and inserted in a terminal hole of a socket body, a plug holder of the plug, and a socket holder of the socket, where the plug holder and the socket holder are connected to each other, where the plug terminal is press fitted in and electrically connected to the socket terminal, where a position in an axial center direction is controlled by sandwiching one end portion of at least one of the plug terminal and the socket terminal between the body and a terminal holder made of an insulating material.

A connector assembly and system assembling an electric connector assembly are provided. The connector assembly includes a connector housing having a plurality of terminal cavities greater than the predetermined number of electric connections so as to define an empty terminal cavity and a filled terminal cavity. The connector housing further includes a blocking member. The blocking member is the blocking member disposed within each of the empty terminal cavities. Accordingly, the blocking member closes off each of the empty terminal cavities so as to prevent fluid transfer between the terminal positioning assurance member and the connector positioning assurance member so as to prevent fluid and debris transfer between the terminal positioning assurance member and the connector positioning assurance member, or stated in another way, prevents fluid and debris transfer between the first open end and the second open end.

A joint connector, including: a connector housing; a joint terminal; a terminal holder; and a lock arm that is formed in an outer peripheral wall of the connector housing, in which a rear end portion of the terminal holder is provided with convex portions that protrude rearward from a rearmost end edge of the connector housing in a proper assembled state of the terminal holder with respect to the connector housing.

A connector unit includes a first connector, a second connector and a seal member to be interposed therebetween. The first connector includes a fitting portion having a distal end portion. The second connector includes a fitted portion. A thickness of the fitting portion is reduced at the distal end portion with an inner peripheral surface of the distal end portion being recessed. The fitted portion includes an attachment portion to which the seal member is to be attached and a housing portion. When the first connector and the second connector are fitted to each other, the distal end portion is accommodated in the housing portion, and the seal member performs sealing between the fitting portion and the fitted portion by being sandwiched between the attachment portion and a portion of the fitting portion, the portion being provided further in a second direction than the distal end portion.
