As the core wire, for example, a twisted wire, a columnar conductor, a cylindrical conductor, etc., may be combined to form a handle. Examples of columnar conductors include single-core wires and busbars. As a material for the core wire, for example, a metal material such as a copper-based material or an aluminum-based material can be used. Each electric wire 20 may be a shielded wire having its own electromagnetic shielding structure, or may be a non-shielded wire having no electromagnetic shielding structure.

The terminal fitting 21 is connected to the core wire of the electric wire 20 . The terminal fitting 21 is, for example, a female terminal. The terminal fitting 21 is connected to a terminal fitting of an object inserted through the opening 34 of the housing 31 .

The housing 31 has a first housing 31F having a front surface 32 and a second housing 31R having a rear surface 33, as shown in FIGS. The second housing 31R is attached to the first housing 31F.

(dummy circuit parts)
As shown in FIGS. 2-4, the wire harness 10 includes a dummy circuit component 60 attached to the connector 30. FIG. The dummy circuit component 60 is a member made of a synthetic resin material. Polypropylene (PP), for example, can be used as the material of the dummy circuit component 60 .

The dummy circuit component 60 has dummy pins 61 inserted into the terminal insertion openings 35 of the connector 30 and connecting portions 70 connecting two adjacent dummy pins 61 .
In this embodiment, the connector 30 has three

dummy circuit components

601, 602, 603 attached.

Dummy circuit components

601 , 602 include three dummy pins 61 . Dummy circuit component 603 includes five dummy pins 61 .

As shown in FIGS. 3 and 4, the dummy pin 61 has a pin body 62 to be inserted into the terminal insertion opening 35 and a flange 66 formed at the rear end of the pin body 62 . The dummy pin 61 is provided at the end opposite to the tip 61</b>A inserted into the terminal insertion opening 35 . The connecting portion 70 is formed between the flanges 66 of two adjacent dummy pins 61 . That is, the connecting portion 70 connects the flanges 66 of two adjacent dummy pins 61 .

The pin body 62 has a locking portion 63 and a seal portion 65 extending from the tip of the locking portion 63 . The collar 66 is formed over the entire circumference of the outer surface of the rear end of the locking portion 63 . In the present embodiment, the engaging portion 63 and the sealing portion 65 are one component formed integrally. In the pin body 62 , the seal portion 65 is first inserted into the terminal insertion opening 35 , and then the locking portion 63 is inserted into the terminal insertion opening 35 .

The seal portion 65 is formed in a columnar shape extending in the insertion direction of the pin body 62, that is, in the Z direction. The outer diameter of the seal portion 65 is larger than the inner diameter of the seal hole 51 . For example, the outer diameter of seal portion 65 is the same as the outer diameter of electric wire 20 . With the dummy circuit component 60 attached to the connector 30 , the seal portion 65 is inserted into the seal hole 51 of the seal member 50 . The seal portion 65 penetrates the seal member 50 . The seal member 50 is in close contact with the outer peripheral surface 65A of the seal portion 65 . In other words, it can be said that the seal portion 65 has a cylindrical seal surface (outer peripheral surface 65A) that comes into close contact with the inner surface of the seal hole 51 of the seal member 50 .

The locking portion 63 is inserted into the terminal insertion opening 35 . In this embodiment, the locking portion 63 is formed in a rectangular parallelepiped shape. The engaging portion 63 has a pair of side surfaces 63A that face opposite sides. In this embodiment, the pair of side surfaces 63A face opposite sides in the Y direction. The locking portion 63 has locking projections 64 projecting from each of the pair of side surfaces 63A. The locking protrusion 64 is formed so as to fit into the locking groove 35A formed in the terminal insertion opening 35. As shown in FIG. That is, the locking protrusion 64 is configured to be engageable with the locking groove 35A. The engagement of the locking protrusion 64 with the locking groove 35A restricts the movement of the dummy pin 61 from the terminal insertion opening 35 to the outside of the connector 30 . As a result, the dummy pin 61 is prevented from coming off. The flange 66 of the dummy pin 61 abuts against the rear surface 33 of the housing 31 to restrict further pushing of the dummy pin 61 .

As shown in FIGS. 5 and 6 , the connecting portion 70 is provided at the end of the flange 66 of the dummy pin 61 opposite to the tip 61 A inserted into the terminal insertion opening 35 .
The connecting portion 70 is formed at the center of the dummy pin 61 in the Y direction orthogonal to the X direction in which the dummy pin 61 is connected. The connecting portion 70 of this embodiment is formed in a symmetrical shape with respect to the center between two adjacent dummy pins 61 . For example, as shown in FIG. 6, the connecting portion 70 is formed line-symmetrically with respect to the axis L1 between two dummy pins 61 adjacent to each other in the X direction when viewed from the Z direction.

The connecting portion 70 has two connecting pieces 70A extending from two dummy pins 61 adjacent in the X direction toward the center (axis line L1) between the two dummy pins 61 adjacent to each other. The two connecting pieces 70A are formed in a symmetrical shape. The connecting pieces 70A are provided on both sides of each dummy pin 61 in the X direction in which the dummy pins 61 are connected. The dummy pins 61 arranged at both ends in the X direction have one connecting piece 70A on the side opposite to the adjacent dummy pins 61 .

The connecting portion 70 has a base end portion 71 connected to two adjacent dummy pins 61 and a connecting center portion 72 between the two base end portions 71 when viewed from the Z direction. In this embodiment, the connecting portion 70 is formed such that the width of the connecting central portion 72 is narrower than the width of the base end portion 71 in the Y direction when viewed from the Z direction. More specifically, the connecting portion 70 is formed so that the width becomes narrower from the base end portion 71 toward the connecting central portion 72 . As a result, the two connecting pieces 70A forming the connecting portion 70 are formed in a trapezoidal shape when viewed from the dummy pin 61 .

(Effect)
Next, the effects of this embodiment will be described.
(1) The dummy circuit component 60 is configured to be attachable to the connector 30 having a plurality of terminal insertion openings 35 . The dummy circuit component 60 includes a plurality of dummy pins 61 that are configured to be insertable into the plurality of terminal insertion openings 35, a connecting portion 70 that connects two adjacent dummy pins 61 among the plurality of dummy pins 61 so as to be detachable, have

Therefore, the plurality of dummy pins 61 connected by the connecting portion 70 can be inserted into the plurality of terminal insertion openings 35 at the same time. As a result, the number of man-hours for inserting the dummy pin 61 can be reduced, and workability can be improved. With such a dummy circuit component 60, workability can be improved in the manufacturing process of the wire harness 10 having the connector 30 with the dummy circuit component 60 inserted therein and the electric wire 20 with the terminal fitting 21 inserted into the connector 30.

(2) The two

dummy circuit components

601 and 602 and the one dummy circuit component 603 have different numbers of connected dummy pins 61 . These dummy circuit parts 60 are formed by connecting more dummy pins 61 . The connecting portion 70 is cut so that the required number of dummy pins 61 are connected to the dummy circuit component 60 . Thereby,

dummy circuit components

601, 602, 603 including the required number of dummy pins 61 can be easily formed. The number of dummy pins 61 included in the dummy circuit component 60 is not limited to the illustrated number, and can be any number.

(3) The connecting portion 70 is formed to connect the flanges 66 of two adjacent dummy pins 61 . The connecting portion 70 is formed thinner than the flange 66 . Therefore, the connecting portion 70 can be easily cut.

(4) The connecting portion 70 is formed narrower than the dummy pin 61 . Therefore, the connecting portion 70 can be easily cut.
(5) The connecting portion 70 is formed at the center of the dummy pin 61 in the Y direction orthogonal to the X direction in which the plurality of dummy pins 61 are connected. For example, in FIG. 6, the dummy pin 61 having the connecting portion 70 formed in the Y direction may bend in an arc shape when viewed from the Z direction depending on the position of the connecting portion 70 . On the other hand, in the dummy circuit component 60 of the present embodiment, the plurality of dummy pins 61 can easily maintain the state of being aligned along the X direction in which they are connected. Therefore, each dummy pin 61 can be easily inserted into the plurality of terminal insertion openings 35 .

(6) The connecting portion 70 has two proximal end portions 71 respectively connected to two adjacent dummy pins 61 and a central connecting portion 72 between the two proximal end portions 71 . The connection center portion 72 is formed to be narrower than the two base end portions 71 when viewed in the Z direction. Therefore, the connecting portion 70 can be easily cut.

(7) The connecting portion 70 has two connecting pieces 70A extending from two adjacent dummy pins 61 respectively. The ends of the two connecting pieces 70A are connected to each other. Therefore, the connecting portion 70 can be easily cut at the tip of the connecting piece 70A.

(8) The two connecting pieces 70A are symmetrical. Therefore, the connecting part 70 is easily cut between the two connecting pieces 70A. Since the two connecting pieces 70A have symmetrical shapes, the connecting pieces 70A of the two adjacent divided dummy pins 61 can be made to have the same length.

(9) The dummy pin 61 has a locking portion 63 and a seal portion 65 extending from the tip of the locking portion 63 . The seal portion 65 is inserted into the seal hole 51 of the seal member 50 of the connector 30 and configured to be in close contact with the inner peripheral surface of the seal hole 51 . Therefore, the seal portion 65 can seal the seal hole 51 .

(10) The locking portion 63 is configured to engage with the locking groove 35A formed in the second housing 31R of the connector 30. The locking portion 63 can prevent the dummy pin 61 (pin main body 62) from coming off. Therefore, it can be said that the locking portion 63 is configured to be capable of restricting movement in the direction in which the pin body 62 is removed from the connector 30 .

(11) In the dummy circuit component 60 , two adjacent dummy pins 61 are connected by the connecting portion 70 . Therefore, a dummy circuit component including one dummy pin 61 can also be configured. Accordingly, even if a single empty housing chamber 40B that is not continuous in the Y direction is set in the connector 30, there is no need to separately prepare a dummy circuit component including one dummy pin 61. FIG. As a result, it is possible to easily deal with changes in the specifications of the connector 30 and the like.
