[0004] By the way, in the connector described in Patent Document 1 mentioned above, for example, the terminal is inserted along the height direction while bending the terminal locking lock and the side wall with respect to the terminal housing portion of the housing member, but there is room for further improvement in more appropriately assembling the wire with a terminal to the housing member.

[0005] The present invention has been made in view of the above circumstances, and an object thereof is to provide a connector and a method for manufacturing a connector that can more appropriately assemble a wire with a terminal to a housing member.

Means for Solving the Problems

[0006] To achieve the above objective, the connector according to the present invention comprises a terminal-equipped wire having a wire extending along the axial direction and a terminal provided at the end of the wire, a terminal housing portion that is open toward one end in the height direction intersecting the axial direction and accommodates the terminal of the terminal-equipped wire, a terminal locking lock provided on the side wall of the terminal housing portion that restricts the movement of the terminal housed in the terminal housing portion along the height direction by contact with the terminal, and a terminal locking block provided on the bottom wall of the terminal housing portion that restricts the movement of the terminal housed in the terminal housing portion along the axial direction by contact with the terminal, wherein the terminal is inserted into the terminal housing portion along the height direction while bending the terminal locking lock and the side wall, and the terminal locking block has a locking surface that locks with the terminal along the axial direction, and an inclined surface that is inclined toward one end in the axial direction as it moves from the locking surface toward the one end in the height direction and guides the terminal toward the locking surface.

[0007] Furthermore, in order to achieve the above objective, the method for manufacturing a connector according to the present invention comprises: a first step in which the terminal of the electric wire with a terminal is inserted along the height direction into a terminal housing portion provided in a housing member and open toward one end in the height direction intersecting the axial direction of the electric wire with a terminal, while bending the side wall of the terminal housing portion and the terminal locking lock provided on the side wall; a second step in which the terminal is guided toward the locking surface of the terminal locking block provided on the bottom wall of the terminal housing portion by an inclined surface that is inclined toward one end in the axial direction as it moves from the locking surface of the terminal locking block toward one end in the height direction; and a third step in which the terminal and the locking surface are locked together along the axial direction. [Effects of the Invention]

[0008] In the connector and method for manufacturing the connector according to the present invention, the terminal locking block has a locking surface that locks with the terminal along the axial direction, and an inclined surface that is inclined toward the one end in the axial direction as it moves from the locking surface toward one end in the height direction, guiding the terminal toward the locking surface. With this configuration, the connector and method for manufacturing the connector can, for example, guide the terminal toward the locking surface with the inclined surface, and thereby absorb misalignment of the terminal along the axial direction relative to the locking surface. As a result, the connector and method for manufacturing the connector have the effect of being able to assemble the wire with the terminal to the housing member more properly.

[Modes for carrying out the invention]

[0010] Embodiments and modifications of the present invention will be described in detail below with reference to the drawings. However, the present invention is not limited by the embodiments and modifications described below. Furthermore, the components in the embodiments and modifications described below include those that are easily substituted or substantially identical to those that are easily substituted by those skilled in the art.

[0011] Furthermore, the embodiments and modifications disclosed below include similar components. Therefore, in the following, these similar components are given common reference numerals, and redundant descriptions are omitted. In this specification, ordinal numbers are used solely to distinguish parts, components, parts, positions, directions, etc., and do not indicate order or priority.

[0012] [Embodiment] Figure 1 is a perspective view of a connector 1 according to an embodiment. The connector 1 of this embodiment shown in Figure 1 is incorporated into a wire harness routed in a vehicle such as an automobile. Here, the wire harness is a bundle of multiple electric wires 11 (electric wires with terminals 10) used for power supply and signal communication to connect various devices mounted on the vehicle, and the electric wires 11 are connected to each device using a connector 1 or the like. The connector 1 of this embodiment includes, for example, multiple electric wires with terminals 10 and a housing member 20 that holds the multiple electric wires with terminals 10. In addition, the connector 1 may also include various other components such as levers and fasteners.

[0013] In the following description, among the first direction, the second direction, and the third direction that intersect each other, the first direction is referred to as the "axial direction X", the second direction is referred to as the "width direction Y", and the third direction is referred to as the "height direction Z". Here, the axial direction X, the width direction Y, and the height direction Z are substantially orthogonal to each other. The axial direction X typically follows the extending direction of the electric wire 11 (electric wire 10 with terminals), the longitudinal direction of the housing member 20, the fitting direction (insertion direction) between the connector 1 and the mating connector, etc. The width direction Y typically follows the radial direction of the electric wire 11, the width direction of the housing member 20 (connector 1), etc. The height direction Z typically follows the radial direction of the electric wire 11, the height direction (vertical direction) of the housing member 20 (connector 1), etc. Also, each direction used in the following description will be described as the direction in the state where the connector 1 is assembled to the vehicle, unless otherwise specified.

[0014] FIG. 2 is an exploded perspective view of the connector 1, and FIG. 3 is a plan view of the housing member 20 of the connector 1. As shown in FIGS. 2 and 3, the housing member 20 is, for example, a so-called kit cut plate that constitutes a part of the inner housing of the connector 1, and holds a plurality of electric wires 10 with terminals and the like inside. In the present embodiment, for example, a plurality of housing members 20 (kit cut plates) to which a plurality of electric wires 10 with terminals are assembled are combined to form the inner housing of the connector 1, and the inner housing is assembled to the outer housing to form the connector 1. In FIGS. 1 to 4 and the like, for the sake of convenience, only one of the plurality of electric wires 10 with terminals is shown.

[0015] The housing member 20 is configured to include, for example, a plurality of terminal accommodating portions 21, a plurality of terminal locking locks 22, and a plurality of terminal locking blocks 23 (see FIG. 3) described later. The terminal accommodating portion 21 is a portion where the terminal 12 of the electric wire 10 with terminals is accommodated, and is open toward one end side (upper side) in the height direction Z. In the present embodiment, three terminal accommodating portions 21 are provided side by side along the width direction Y in the housing member 20. Note that the number of terminal accommodating portions 21 is not limited to this example, and for example, one, two, or four or more terminal accommodating portions 21 may be provided.

[0016] The terminal housing portion 21 is configured to include, for example, a pair of side walls 21a and a bottom wall 21b. The bottom wall 21b is a portion that supports the lower surface of the terminal 12, and is formed in a flat surface shape extending along a direction (XY plane) intersecting the height direction Z. The pair of side walls 21a are portions that support the side surfaces of the terminal 12, protrude along the height direction Z from the bottom wall 21b, and extend along the axial direction X. In the present embodiment, for example, in two adjacent terminal housing portions 21 along the width direction Y, one of the pair of side walls 21a is shared. That is, in the present embodiment, a total of four side walls 21a are provided for the three terminal housing portions 21 arranged along the width direction Y. The pair of side walls 21a of the terminal housing portion 21 disposed at the central portion among the three terminal housing portions 21 also function as partition walls that partition the adjacent terminal housing portions 21 along the width direction Y.

[0017] The terminal locking lock 22 is provided on the side wall 21a of the terminal housing portion 21, and restricts the movement of the terminal 12 accommodated in the terminal housing portion 21 along the height direction Z by abutting against the terminal 12. The terminal locking lock 22 is formed, for example, in a claw shape at one end (upper end) in the height direction Z on the side wall 21a. In the present embodiment, for example, in each terminal housing portion 21, three terminal locking locks 22 are provided side by side along the axial direction X on one of the pair of side walls 21a. Each terminal locking lock 22 has a locking surface that is locked along the height direction Z with the upper surface of the terminal 12. In the present embodiment, for example, in a state where the terminal 12 is accommodated in the terminal housing portion 21, the movement (removal) of the terminal 12 along the height direction Z with respect to the terminal housing portion 21 is suppressed by locking the locking surface of the terminal locking lock 22 and the upper surface of the terminal 12 along the height direction Z.

[0018] Figure 4 is a perspective view (partial cross-sectional view) of connector 1, and Figure 5 is a cross-sectional view of connector 1 showing the state before the terminal 12 is inserted into the terminal housing 21. As shown in Figures 4 and 5, the wire with terminal 10 is composed of a wire 11 and a terminal 12 provided at the end of the wire 11. The wire 11 is composed of a conductive linear conductor portion 11a (see Figure 5) and an insulating coating portion 11b that covers the outside of the conductor portion 11a. The wire 11 is an insulated wire in which the conductor portion 11a is covered with the insulating coating portion 11b. In this embodiment, the conductor portion 11a is a core wire made by bundling a plurality of conductive metal strands, but it may also be a stranded core wire made by twisting a plurality of metal strands together.

[0019] The electric wire 11 extends linearly along the axial direction X and is formed to extend with approximately the same diameter as the axial direction X (extension direction). For example, the electric wire 11 has a substantially circular cross-sectional shape at the conductor portion 11a (the cross-sectional shape intersecting the axial direction X) and a substantially annular cross-sectional shape at the insulating coating portion 11b, resulting in an overall substantially circular cross-sectional shape. At least one end of the electric wire 11 has the insulating coating portion 11b stripped off, and the terminal 12 is connected to the conductor portion 11a exposed from the insulating coating portion 11b.

[0020] Terminal 12 is a female terminal fitting made of, for example, a conductive metal material, and is electrically connected to the mating terminal of the mating connector. Terminal 12 is composed of, for example, an electrical connection portion 12a, a conductor connection portion 12b, and a covering connection portion 12c. The electrical connection portion 12a is locked to the locking surface 23a (see Figure 5) of the terminal locking block 23, which will be described later, and is electrically connected to the mating terminal. The electrical connection portion 12a is provided with, for example, a terminal insertion portion (contact portion) into which the mating terminal is inserted along the axial direction X.

[0021] The covering joint 12c is provided at the end opposite to the electrical connection 12a in the axial direction X, and is the part that is joined to the insulating coating 11b of the electric wire 11. The covering joint 12c is joined to the insulating coating 11b of the electric wire 11, for example, by crimping. The conductor joint 12b is provided between the electrical connection 12a and the covering joint 12c in the axial direction X, and is the part that is joined to the conductor portion 11a of the electric wire 11. The conductor joint 12b is joined to the conductor portion 11a of the electric wire 11, for example, by crimping. Note that the joining method of the conductor joint 12b and the covering joint 12c is not limited to this example, and for example, the conductor portion 11a and the insulating coating 11b of the electric wire 11 may be joined by laser welding, ultrasonic bonding, heat welding, etc.

[0022] Figure 6 is a perspective view of the connector 1 showing the state in which the terminal 12 is being inserted into the terminal housing 21, and Figure 7 is a perspective view of the connector 1 showing the state after the terminal 12 has been inserted into the terminal housing 21. As shown in Figures 6 and 7, the terminal locking block 23 is provided, for example, on the bottom wall 21b of the terminal housing 21, and restricts the movement of the terminal 12 housed in the terminal housing 21 along the axial direction X by contact with the terminal 12. In this embodiment, for example, a terminal locking block 23 is provided on the bottom wall 21b of each terminal housing 21, and these multiple terminal locking blocks 23 are arranged along the width direction Y.

[0023] The terminal locking block 23 is composed of, for example, a locking surface 23a, an inclined surface 23b, and a base surface 23c. The locking surface 23a is the portion of the terminal locking block 23 that locks with the electrical connection portion 12a of the terminal 12 along the axial direction X, and extends along the height direction Z. In this embodiment, for example, the terminal locking block 23 is provided projecting along the height direction Z from the bottom wall 21b of the terminal housing portion 21, and the locking surface 23a is formed by the end face (side surface) of the terminal locking block 23 along the axial direction X. The terminal locking block 23 protrudes in a two-stage manner, for example, having a first protruding portion 23e having a locking surface 23a and a base surface 23c, and a second protruding portion 23f having an inclined surface 23b and protruding along the height direction Z from the first protruding portion 23e.

[0024] The inclined surface 23b is the portion of the terminal locking block 23 that guides the electrical connection portion 12a of the terminal 12 toward the locking surface 23a. The inclined surface 23b is inclined such that, for example, it moves toward one end (upper side) in the height direction Z from the locking surface 23a of the first protruding portion 23e toward one end (upper side) in the axial direction X. The inclined surface 23b is formed, for example, by the end face (side surface) in the axial direction X of the second protruding portion 23f of the terminal locking block 23 described above. The second protruding portion 23f is formed in a substantially trapezoidal cross-section having, for example, the inclined surface 23b, a flat top surface extending from the inclined surface 23b along the axial direction X, and an inclined surface that is inclined symmetrically with respect to the inclined surface 23b from the top surface.

[0025] The base surface 23c is the part of the terminal locking block 23 that supports the conductor joint portion 12b of the terminal 12. The base surface 23c extends, for example, along the axial direction X, and by contacting the conductor joint portion 12b, it can suppress the inclination of the conductor joint portion 12b and the insulated joint portion 12c relative to the electrical connection portion 12a. The base surface 23c is formed, for example, by one end surface (upper surface) in the height direction Z of the first protruding portion 23e in the terminal locking block 23 described above. That is, the base surface 23c is a flat surface in the terminal locking block 23 that is one step lower than the second protruding portion 23f on which the inclined surface 23b is formed, and is positioned offset from the second protruding portion 23f (electrical connection portion 12a) toward one end side in the axial direction X (towards the electric wire 11).

[0026] Next, an example of a manufacturing method (assembly method) for the connector 1 having the above configuration will be described. Figure 8 is a flowchart showing the manufacturing method of the connector 1, and Figure 9 is an explanatory diagram showing the manufacturing method of the connector 1. As shown in Figures 8 and 9, first, in the first step S1, the terminals 12 are inserted into the terminal housing portion 21 along the height direction Z while bending the side wall 21a and the terminal locking lock 22. In this case, the terminals 12 of multiple terminal-equipped electric wires 10 are inserted sequentially into multiple terminal housing portions 21 from one end to the other end in the width direction Y.

[0027] At this time, the multiple terminal-equipped wires 10 are inserted sequentially from the terminal housing 21 side (left side in Figure 9) that has a side wall 21a that does not have a terminal locking lock 22. This allows for elastic deformation of the terminal locking lock 22 and the side wall 21a provided with the terminal locking lock 22 along the width direction Y during the insertion process of the terminal-equipped wires 10 into the terminal housing 21, thereby improving the ease of assembling the multiple terminal-equipped wires 10 into the multiple terminal housing 21.

[0028] Next, in the second step S2, as shown in Figures 6 and 8, the terminal 12 is guided toward the locking surface 23a by the inclined surface 23b with respect to the terminal locking block 23. In this case, one end of the electrical connection portion 12a of the terminal 12 in the axial direction X (the end on the conductor joint portion 12b side) comes into contact with the inclined surface 23b, and the electrical connection portion 12a is guided by the inclined surface 23b.

[0029] Next, in the third step S3, as shown in Figures 7 and 8, the terminal 12 and the locking surface 23a are locked together along the axial direction X. In this case, one end of the electrical connection portion 12a in the axial direction X abuts against the locking surface 23a, and the electrical connection portion 12a and the locking surface 23a are locked together along the axial direction X. Through these first steps S1 to the third step S3, multiple terminal-equipped wires 10 can be assembled into multiple terminal housing portions 21 to manufacture the connector 1. Note that the manufacturing method of the connector 1 is not limited to this example, and may include, for example, a step of combining several housing members 20 (KitKat plates) to which multiple terminal-equipped wires 10 are assembled to form the inner housing of the connector 1.

[0030] As described above, in the connector 1 and the manufacturing method of the connector 1 of this embodiment, the terminal locking block 23 has a locking surface 23a that locks with the terminal 12 along the axial direction X, and an inclined surface 23b that is inclined toward one end in the axial direction X as it moves toward one end in the height direction Z from the locking surface 23a, and guides the terminal 12 toward the locking surface 23a. With this configuration, the connector 1 and the manufacturing method of the connector 1 can, for example, guide the terminal 12 toward the locking surface 23a by the inclined surface 23b, and thereby can absorb the misalignment of the terminal 12 along the axial direction X with respect to the locking surface 23a. As a result, the connector 1 and the manufacturing method of the connector 1 can assemble the wire 10 with the terminal to the housing member 20 more properly.

[0031] Furthermore, in the connector 1 of this embodiment, the terminal 12 is configured to include an electrical connection portion 12a that is locked to a locking surface 23a and electrically connected to a mating terminal, and a conductor connection portion 12b that is joined to the conductor portion 11a of the electric wire 11. The terminal locking block 23 extends along the axial direction X and has a base surface 23c that supports the conductor connection portion 12b. With this configuration, the connector 1 can, for example, suppress the tilting of the conductor connection portion 12b and the insulation connection portion 12c relative to the electrical connection portion 12a by the base surface 23c, and thereby correct and hold the electric wire 10 with terminals in the proper position.

[0032] Furthermore, in the connector 1 of this embodiment, the housing member 20 has a plurality of terminal locking locks 22, and the plurality of terminal locking locks 22 are provided on one of a pair of side walls 21a of the terminal housing portion 21, arranged along the axial direction X. With this configuration, the connector 1 can, for example, lock the terminal 12 with the plurality of terminal locking locks 22, and when a plurality of terminal housing portions 21 are provided arranged along the width direction Y, the side wall 21a on which the plurality of terminal locking locks 22 are provided can bend along the width direction Y toward the adjacent terminal housing portion 21, thereby further improving the ease of assembling the wire with terminals 10 to the housing member 20.

[0033] [Differentiation] Figure 10 is a perspective view of a modified connector 1A. The connector 1A shown in Figure 10 has the same configuration as connector 1 in the above embodiment. Therefore, connector 1A can obtain the same operation and effects as the above embodiment based on the same configuration.

[0034] However, this modified example differs from the above embodiment in that, as shown in Figure 10, the housing member 20 is provided with one terminal housing portion 21, and the terminal locking lock 22 is provided on each of the pair of side walls 21a of the terminal housing portion 21. That is, in this modified example, the terminal locking lock 22 is configured to include a first terminal locking lock 22A provided on one of the pair of side walls 21a, and a second terminal locking lock 22B provided on the other of the pair of side walls 21a.

[0035] In this modified example, for instance, the first terminal lock 22A is provided in a pair on one of the pair of side walls 21a, spaced apart from each other along the axial direction X. On the other hand, the second terminal lock 22B is provided on the other of the pair of side walls 21a, positioned between the pair of first terminal locks 22A. That is, the first terminal lock 22A and the second terminal lock 22B are provided on each of the pair of side walls 21a, offset from each other along the axial direction X.

[0036] Next, an example of a manufacturing method (assembly method) for the connector 1A having the above configuration will be described. Figure 11 is an explanatory diagram showing a modified example of a manufacturing method for the connector 1A. As shown in Figure 11, first, in the first step S1, the terminal 12 is inserted into the terminal housing portion 21 along the height direction Z while bending the side wall 21a and the terminal locking lock 22. In this case, as the terminal 12 is inserted into the terminal housing portion 21, the first terminal locking lock 22A and the second terminal locking lock 22B and the pair of side walls 21a elastically deform toward the sides that are separated from each other along the width direction Y.

[0037] Next, in the second step S2, as shown in Figure 6, the terminal 12 is guided toward the locking surface 23a by the inclined surface 23b with respect to the terminal locking block 23. In this case, one end of the electrical connection portion 12a of the terminal 12 in the axial direction X (the end on the conductor joint portion 12b side) comes into contact with the inclined surface 23b, and the electrical connection portion 12a is guided by the inclined surface 23b.

[0038] Next, in the third step S3, as shown in Figure 7, the terminal 12 and the locking surface 23a are locked together along the axial direction X. In this case, one end of the electrical connection portion 12a in the axial direction X abuts against the locking surface 23a, and the electrical connection portion 12a and the locking surface 23a are locked together along the axial direction X. Through these first steps S1 to the third step S3, the wire with terminals 10 can be assembled to the terminal housing portion 21, and the connector 1A can be manufactured. Note that the manufacturing method of the connector 1A is not limited to this example, and may include, for example, a step of combining several housing members 20 (KitKat plates) to which the wire with terminals 10 is assembled to form the inner housing of the connector 1A.

[0039] As described above, in the modified connector 1A, the housing member 20 has a plurality of terminal locking locks 22, and the plurality of terminal locking locks 22 are provided on each of the pair of side walls 21a of the terminal housing portion 21, offset from each other along the axial direction X. With this configuration, the connector 1A can lock the terminal 12 by the plurality of terminal locking locks 22, and the movement (dislodgement) of the terminal 12 along the height direction Z relative to the terminal housing portion 21 can be further suppressed by the terminal locking locks 22 provided alternately.

[0040] In this modified example and the above embodiment, an example is given in which three terminal locking locks 22 are provided on a pair of side walls 21a of the terminal housing 21. However, the invention is not limited to this example, and for example, one, two, or four or more terminal locking locks 22 may be provided on a pair of side walls 21a of the terminal housing 21. Also, in this modified example and the above embodiment, an example is given in which a base surface 23c is provided on the terminal locking block 23. However, the invention is not limited to this example, and for example, a base surface 23c may be provided on the bottom wall 21b of the terminal housing 21.

[0041] Although embodiments and modifications of the present invention have been illustrated above, these embodiments and modifications are merely examples and are not intended to limit the scope of the invention. The above embodiments and modifications can be implemented in various other forms, and various omissions, substitutions, combinations, and changes can be made without departing from the spirit of the invention. Furthermore, each configuration, shape, and other specifications (structure, type, direction, form, size, length, width, thickness, height, number, arrangement, position, material, etc.) can be modified as appropriate.
