[Description of Embodiments of the Present Disclosure]
First, embodiments of the present disclosure are enumerated and described.

(1) A connector according to the present disclosure includes a terminal connected to a front end of an electric wire, and a housing that accommodates the terminal, and the housing extends rearward from a position that accommodates the terminal. a placement portion on which the electric wire is placed; and a lid portion formed so as to be movable between a position covering the placement portion and a position separated from the placement portion, wherein the lid portion has an electric wire pressing portion that presses the electric wire placed on the placing portion toward the placing portion at a position covering the placing portion.

Since the electric wire is sandwiched between the mounting portion and the cover provided on the housing, the number of parts can be reduced compared to the case where a cover that is separate from the housing is used. This can reduce the manufacturing cost of the connector.

Since the electric wire is sandwiched between the placing portion and the electric wire pressing portion, transmission of an external force applied to the electric wire to the terminal is suppressed.

(2) It is preferable that an outer housing is provided in which the housing is accommodated, and that the outer housing covers the lid portion from the outside.

Since the outer housing covers the lid, opening of the lid is suppressed. Thereby, an electric wire can be pinched reliably.

(3) It is preferable that at least two lid portions are provided so as to sandwich the placement portion.

In a connector in which electric wires are placed on both one side and the other side of the placing portion by arranging the wires side by side with the placing portion interposed therebetween, the electric wires are placed on both sides of the placing portion. The electric wire thus placed can be pressed by the cover portion provided with the placement portion interposed therebetween.

(4) One of the at least two lid portions protrudes toward the other lid portion provided on both sides of the mounting portion, and at a position covering the mounting portion, at least two of the lid portions are provided. It is preferable that the lid portion is provided with an opening stop portion that engages with another lid portion.

The opening stopper can prevent the lid from opening.

(5) An outer housing in which the housing is accommodated is provided, and at least one of the one lid portion and the other lid portion is provided with a rib protruding from the outer surface of the lid portion. Preferably, the outer housing is provided with a lid pressing portion that presses the rib toward the other lid portion.

In a state in which one lid is locked to the other lid by the opening stopper, the one lid is generally provided with play in the locked portion, so that the one lid is It will rattle. Due to this rattling, the pressure applied to the wire by the wire pressing portion is weakened, and the wire holding performance of the housing is reduced. Therefore, by pressing a rib provided on one of the lid portions or the other lid portion toward the other lid portion with a lid pressing portion provided on the outer housing, the backlash of the lid portion is eliminated. Sticking is suppressed, and the wire holding performance of the housing can be improved.

(6) The one lid portion is engaged with the other lid portion in a vertical direction that intersects with the lead-out direction of the electric wire, and the rib is arranged on the cover portion in the lead-out direction of the electric wire and the vertical direction. It is preferable that it is provided on the side portion in the left-right direction that intersects with the .

Since the ribs are provided on the sides in the left-right direction, for example, compared to a structure in which the ribs are provided on the sides in the up-down direction, the joint portion of one lid and the other lid can be opened. can be suppressed.

(7) The outer housing has an opening that opens to the rear, and has an accommodating portion in which the housing is accommodated from the opening, and the lid pressing portion is recessed from the rear surface of the opening edge of the opening. , the rib is located on the rear end side of one of the lid portions and is housed in the lid pressing portion from the rear, and the inner surface of the lid pressing portion is attached to the rib on the other lid portion. It is preferable that one of the lid portions is pushed toward the other lid portion by contacting from the direction toward the two.

The lid pressing portion has a shape recessed from the rear surface of the opening edge, and the rib is located on the rear end side of the lid portion. It means that the rib is not pressed. As a result, compared to a configuration in which the rib is located on the front end side of the lid portion, the workability of accommodating the housing in the outer housing can be improved.

(8) It is preferable that the lid portion is provided with a protrusion projecting from the outer surface of the lid portion and coming into contact with the inner surface of the accommodating portion.

The contact of the convex portion with the inner surface of the housing portion can suppress the bulging of the lid portion.

(9) The housing has a strain relief portion that holds the wire in a state of being bent in a direction that intersects the front-rear direction, and the strain relief portion is provided at a position rearward of the wire pressing portion. is preferred.

Since the wire is held in a bent position in the front-rear direction by the strain relief portion, the external force applied to the wire is absorbed by the bent portion of the wire. This reliably suppresses transmission of an external force applied to the wire to the terminal.

(10) A binding member wound around the outside of the housing is provided, and the binding member sandwiches the electric wire between the lid portion and the placement portion at a position behind the electric wire pressing portion in the housing. It is preferably wound in a closed state.

Since the binding member prevents the lid from opening, the wires can be firmly held between the lid and the mounting portion.

(11) It is preferable that the lid portion has an auxiliary projection projecting toward the electric wire in a region around which the binding member is wound.

The pressing force applied by the binding member is reliably transmitted to the electric wire via the auxiliary protrusion. Thereby, the electric wire can be reliably held by the lid.

(12) The terminal includes a clamping portion that clamps the electric wire, and a shell fitted to the outside of the clamping portion, and the shell is a pressing portion that presses the clamping portion toward the electric wire. It is preferred to have

The clamping portion clamps the electric wire by being pressed by the pressing portion provided on the shell. As a result, since the terminal and the wire are electrically connected, a large-scale equipment investment such as a jig for crimping is not required, so that the manufacturing cost of the terminal can be reduced.

(13) The lid portion can be rotated from a position away from the mounting portion to a position covering the mounting portion, and the wire pressing portion has a shape protruding from the lid portion. and a first contact portion, which is a portion of the wire pressing portion that comes into first contact with the wire when the lid portion is rotated to a position covering the placement portion, has a rectangular shape. preferable.

Since the front contact part has a rectangular shape, the wire pressing part is pushed when the cover rotates from the position away from the placing part to the position covering the placing part (that is, when the lid part is closed). becomes easy to bite into the electric wire. Thereby, the electric wire holding force can be improved. In addition, for example, compared to the case where the tip contact portion has a round shape, the lid portion can be closed more easily, so that the assembling efficiency of the connector can be improved.

(14) The wire pressing portion includes a planar upright surface portion rising from the lid portion, and a planar tip end surface portion extending rearward in the wire lead-out direction from the tip of the upright surface portion, and It is preferable that the first contact portion is a rectangular portion between the upright surface portion and the tip surface portion, and the angle between the upright surface portion and the tip surface portion is 90 degrees or less.

With the above configuration, the first contact portion can be brought into first contact with the electric wire when the lid portion is closed by turning.

(15) It is preferable that a base end surface of the lid portion, which is continuous with a base end of the wire pressing portion, contacts the wire when the lid portion covers the mounting portion.

The contact of the base end surface with the electric wire can prevent the electric wire pressing portion from excessively biting into the electric wire. Thereby, for example, it is possible to suppress that the insulation coating of the electric wire is torn.
