Set to dimensions. That is, both end portions in the width direction of the terminal holding portion 43 form first projecting portions 43 b that project outward from the outer surfaces of the left and right side walls 42.
Here, the electrical contact portions 32 of the joint terminal 30 are arranged in a direction parallel to the width direction thereof, and the terminal holding portion 43 also has a shape extending in the arrangement direction. The width dimension in the direction orthogonal to the arrangement direction is kept small.
Each partition wall 44 is located between the electrical contact portions 32 adjacent to each other among the joint terminals 30 held by the terminal holding portion 43, and is connected to the connector housing 40 from the inner surface of the main body wall 41. Projecting inward (upward in the posture of the joint connector JC shown in FIG. 9). These partition walls 44 extend continuously and linearly from the terminal holding portion 43 to the opposite end portion (front end portion of the connector housing 40).
The partition walls 44 adjacent to each other define a terminal accommodating chamber 47 into which the electric wire side terminal 20 to be connected to the electrical contact portion 32 can be inserted. These terminal accommodating chambers 47 are opened to the front end side (the side opposite to the terminal holding portion 43) of the connector housing 40, and the electric wire side terminal 20 is inserted from the opening.
As shown in FIGS. 9 and 10, each partition wall 44 includes a central wall portion 44 a interposed between the main body wall 41 and the lance 46, a rear end of the lance 46, and the terminal holding portion 43.

The central wall 44a has a protruding dimension smaller than the shortest distance from the main body wall 41 to the lance 46, while the rear side wall 44b and the front side wall 44c both protrude larger than the shortest distance. Have dimensions. In other words, each partition wall 44 has a rectangular shape that allows the partition wall 44 to avoid the presence region of the lance 46 when viewed from a direction parallel to the arrangement direction of the electrical contact portions 32 of the joint terminals. A notch 44d having a shape is formed.
The auxiliary wall 45 is formed in a front side portion of the connector housing 40 (a portion opposite to the terminal holding portion 43), and each terminal accommodating chamber 47 is disposed on a side opposite to the main body wall 41 (shown in FIG. 9 and the like). The joint connector JC is connected to the side walls 42 and the partition walls 44 so as to cover the joint connector JC from above. That is, each terminal accommodating chamber 47 is surrounded by the main body wall 41, the auxiliary wall 45, and the partition wall 44 or the side wall 42 from four directions.
Each of the lances 46 is inserted into the terminal accommodating chamber 47 and locks the electric wire side terminal 20 fitted to the electric contact portion 32. These lances 46 are provided for each of the terminal accommodating chambers 47. These lances 46 are formed integrally with the auxiliary wall 45 and have a shape extending rearwardly (in the direction toward the terminal holding portion 43) from the auxiliary wall 45, and are exposed to the outside so as to be connected to the connector housing 40. A part of the outer wall 49 is formed. Specifically, the outer surface 46b of the lance 46 opposite to the main body wall 41 is exposed to the outside. In this way, in this joint connector JC, each lance 46 is formed integrally with the outer wall 49 of the connector housing 40, so that the lance 46 is provided inside the terminal accommodating chamber 47 such as the inner surface of the auxiliary wall 45, for example. Compared to the case, the width dimension of the connector housing 40 is reduced.
At the end of each lance 46, a locking portion 46a is formed that contacts the stepped portion 22a formed on the top wall 22b of the electrical contact portion 22 of the wire side terminal 20 and locks the wire side terminal 20. ing. Each locking portion 46a has a claw shape that can come into contact with the stepped portion 22a formed on the upper surface of the electric wire side terminal 20 from the front side (right side in FIG. 3) of the connector housing 40, The electric wire side terminal 20 is prevented from coming out of the connector housing 40. Then, each lance 46 has an end portion where the locking portion 46a is formed retracted outward from the main body wall 41 from the locking position at which the wire side terminal 20 is locked, and the wire side terminal 20 is engaged. It is a free end that can be deflected and displaced toward the lock release position for releasing the stop state (downward in FIG. 3 and upward in FIGS. 9 and 10).
On the front end side of the main body wall 41, a second projecting portion 48 is formed that extends in the arrangement direction of the electrical contact portions 32 of the joint terminal 30 and projects outward. The distance between the second protrusion 48 and the first protrusion 43b (the distance in the direction parallel to the insertion direction of the electric wire side terminal 20 into the connector housing 40) is set to be substantially equal to the width of the tape 58. Has been.
Next, a method of assembling the wire harness 100 by short-circuiting each electric wire side terminal 20 using the joint connector JC configured as described above and fixing the joint connector JC to the trunk line 56 of the wire harness will be described. .
First, the wire-side terminal 20 crimped to the end of the wire 10 is inserted into the terminal accommodating chamber 47 while the lance 46 is moved from the locking position to the locking release position by the top wall 22b. When the electric wire side terminal 20 is inserted to a predetermined position, the step portion 22a of the electric wire side terminal 20 and the locking portion 46a of the lance 46 are engaged, and the lance 46 is elastically returned to the original position (locking position). To do. At this time, the electric wire side terminal 20 and the electrical contact portion 32 of the joint terminal 30 are fitted and electrically connected.
In this way, all the electric wire side terminals 20 are inserted into the terminal accommodating chamber 47 and electrically connected to the joint terminal 30. Thereby, each electric wire side terminal 20 is mutually short-circuited via the joint terminal 30 (short circuit process).
Next, the joint connector JC locked to the locking portion 46a of the lance 46 is fixed to the outer peripheral surface of the trunk wire 56 of the wire harness in a state where all the wire side terminals 20 are short-circuited with each other.
Specifically, first, the side surface of the outer wall 49 of the connector housing 40 on the side where the lance 46 is formed, that is, the side surface on the auxiliary wall 45 side and the outer peripheral surface of the main wire 56 of the wire harness face each other. The joint connector JC is installed on the outer peripheral surface of the trunk line 56 of the wire harness. At this time, as shown in FIG. 1, the axial direction of the electric wire 10 and the axial direction of the main wire 56 of the wire harness are matched so that the electric wire 10 drawn from the main wire 56 of the wire harness is not twisted. In this state, the arrangement direction of the electrical contact portions 32 of the joint terminal 30 is orthogonal to the axial direction of each electric wire 10, and the amount of protrusion of the joint connector JC from the outer peripheral surface of the trunk line 56 of the wire harness is suppressed. In this state, the first protrusion 43b protrudes in the width direction of the main wire 56 of the wire harness, and the second protrusion 48 protrudes outward from the main wire 56 of the wire harness.
Next, on the basis of the first protrusion 43b and the second protrusion 48, a tape 58 is wound around a region between the first protrusions 43b and 48, and the joint connector JC is connected to the wire by the tape 58. It fixes to the outer peripheral surface of the trunk trunk line 56 of a harness. At this time, the outer surface 46b exposed to the outside of the lance 46 is in contact with the trunk line 56 of the wire harness, and this contact restricts the displacement of the lance 46 to the unlocking position (joint connector). Fixing process).
Thus, in this wire harness 100, the amount of protrusion of the joint connector JC from the main wire 56 of the wire harness is kept small, and the main wire 56 of the wire harness allows the displacement of the lance 46 to the unlocking position. The locking force of each electric wire side terminal 20 is ensured by being regulated. In addition, as described above, the distance between the first protrusion 43b and the second protrusion 48 is set to be approximately equal to the width of the tape 58, so that the tape is determined based on the protrusions 43b and 48. 58 can be easily wound. Furthermore, the joint connector JC is stably fixed by suppressing the deviation of the tape 58 by the protrusions 43b and 48.
And if the protrusion amount from the trunk wire 56 of the wire harness of the joint connector JC is suppressed small as mentioned above, the wire harness 100 is easily accommodated inside the corrugated pipe (protective pipe) 60 as shown in FIG. be able to. The corrugated pipe 60 is a pipe that can be bent and deformed along the trunk line 56 of the wire harness. Here, FIG. 11 is a view in which a portion of the corrugated pipe 60 is cut so that the inside can be seen. In actual use, the periphery of the wire harness 100 is covered with the corrugated pipe 60.
If the trunk wire 56 of the wire harness can be accommodated inside the corrugated pipe 60 with the joint connector JC fixed in this manner, the wire harness trunk wire 56 is damaged, the impact applied to the joint connector JC, and the electric wire side The disconnection of the terminal 20 from the joint connector JC can be suppressed.
Here, the second protruding portion 48 can function as a held portion held by a jig when testing the tensile strength of the electric wire 10 connected to the joint connector JC. An example of a jig for performing this tensile test is shown in FIG. The jig 50 shown in this figure has a container shape that can store the entire joint connector JC, and has a window 52 for leading the electric wire 10 connected to the joint connector JC to the outside of the jig 50. is doing. Further, an abutting wall 54 that can abut against the protruding portion 48 from the outside is formed at the peripheral edge of the window 52.
The tensile test is performed by applying a tensile load to the electric wire 10 in a state where the joint connector JC is stored in the jig 50. At this time, since the protrusion 48 and the contact wall 54 come into contact with each other, it is prevented from being detached from the joint connector JC from the jig 50, so that an appropriate tension is applied to the electric wire 10 connected to the joint connector JC. A load can be applied.
The first projecting portion 43b and the second projecting portion 48 can be omitted. However, if these protrusions 43b and 48 are provided, the tape 58 can be easily wound around the joint connector JC, and the position of the tape 58 can be stabilized. Further, as described above, the second projecting portion 48 can function as the held portion during a tensile test.
The specific shape of the first protrusion 43b is not limited to the above. However, if the width dimension of the terminal holding portion 43 is set large and the first protruding portion 43b is formed by both ends in the width direction, the holding force of the joint terminal 30 by the terminal holding portion 43 is ensured. In addition, an effect such as positioning of the tape 58 can be obtained without providing the first protrusion 43b separately.
Further, the number of the electric wires 10 to be short-circuited is not limited to the above.
