A terminal connecting mechanism includes a plate spring, an insulating housing having an accommodating portion to accommodate a fixed portion and an elastic portion of the plate spring, and a terminal electrode portion disposed in the accommodating portion. The accommodating portion includes a first opening to allow a conductor portion of an electric wire to be inserted into the accommodating portion, an electric wire insertion guide wall disposed from the first opening along an insertion direction of the electric wire, to guide the conductor portion, an inclined wall facing the electric wire insertion guide wall and being inclined toward the electric wire insertion guide wall along the insertion direction of the electric wire, wherein the fixed portion is fixed to the inclined wall, and a second opening to allow a jig to be inserted into the accommodating portion, thereby canceling contact between the elastic portion and the conductor portion.

A photovoltaic junction box comprising a diode module and a circuit board disposed in a box body, and a heat sink mounted on the outer surface of the box body. The diode module is attached to the back side of the heat sink and is electrically connected to cooper conductor. The heat sink is made of aluminum material and a heat-absorbing layer is provided inside the heat sink. The heat-absorbing layer is close to the diode module. The aluminum heat sink provides great thermal conductivity, therefore, can greatly increase the cooling capacity of the junction box. In addition, because metal material for higher temperature resistance is used instead of lower temperature resistance plastic material, the box body would not deform as easy, greatly increase the safety and reliability of the junction box.

An electronic-component-equipped terminal block includes a terminal block including first and second through holes provided in a front wall; an electronic component including a component body first and second leads; and an electrically insulating attachment assistance tool. The attachment assistance tool includes a base portion arranged outside a housing such that a rear surface thereof abuts against the front wall; and first and second insertion portions protruding from the rear surface of the base portion to be thereby inserted into the first and second through hole, respectively. The attachment assistance tool is provided with a first passage portion through which the first lead is inserted, and a second passage portion through which the second lead is inserted, and a receiving portion that receives and accommodates a rear portion of the component body is provided at a front-side position.

An electrical connection box applied to a wire harness includes a casing that includes an accommodating space that is formed therein and that accommodates an electronic component, and a guiding space that is partitioned horizontally lateral to the accommodating space therein via a partition wall, and that extends in a vertical direction and guides water entered therein to a vertically downside. The casing includes a water-preventing rib that is provided in the guiding space, and that guides water guided to the vertically downside in the guiding space, in a direction of avoiding from an avoidance target portion that is positioned vertically below the guiding space.

The present invention concerns a connection system comprising: a plurality of connection plugs on each of which is mounted a locking lever with two arms each one supporting a locking hook of a locking system, an assembly comprising: an electrical equipment box panel, designed to lodge an electronic circuit card, the panel comprising a plurality of openings; a plurality of adjacent sockets.

According to the invention, the plurality of sockets is monobloc with the equipment panel and the sockets and the plugs are configured such that when each plug is connected to one of the sockets and locked to the latter by means of the locking lever in the position of attachment of the hooks to the locking lugs of the socket, two adjacent arms of adjacent plugs are in planar, pointlike or linear bearing against each other.

[Problem] To allow a plurality of connection terminals to be reliably arranged in a storage case, and the storage case to be placed into a housing. [Means for Resolution] A storage case 1 has a storage portion 2 in which female connection terminals T including connection portions at front ends are arranged in parallel along storage grooves 2d, and a cover 3 that covers the storage portion 2, and tubular temporarily storing portions 2i for inserting tips of connection portions Ta of the female connection terminals T for temporary storage are provided at the fronts of the respective storage grooves 2d.

A terminal block including: a connector that has a tubular shape; and a seating that is formed on an outer periphery of the connector, and is to be fixed to the housing so as to close an opening of the housing, wherein: the seating includes: a first wall that extends in a direction that intersects an axial direction of the connector; a second wall that faces the first wall in the axial direction of the connector; a rib that is provided between the first wall and the second wall so as to connect the first wall and the second wall with each other; and a space that is partitioned by the rib between the first wall and the second wall, and the space is open in a direction that intersects the axial direction of the connector.

The present invention relates to a terminal (1) with a spring force terminal connection (2) with at least one conductor terminal point (K), an insulating material housing (6), a conductor introduction channel (60), and a release lever (5). The release lever (5) is mounted in the insulating material housing (6) pivotably about a pivot axis (A) extending transverse to a conductor introduction direction (E) of an electric conductor between an idle position with closed conductor terminal point (K) and an actuating position with opened conductor terminal point (K). The release lever (5) has two lever arm portions (50) which are spaced apart from one another and which are immersed on both sides of the conductor introduction channel (60) at least partially into the insulating material housing (6). The lever arm portions (50) have in each case a guide portion (53) which face one another and form between them at least a part of the conductor introduction channel (60). The guide portions (53) in the idle position and/or in the actuating position, as seen in the conductor introduction direction, run toward the conductor terminal point (K) in a manner which narrows the conductor introduction channel (60).
