Description

[Technical field]

[0001] The present invention relates to a connector. [Background technology]

[0002] In a connector, an electric wire with a terminal is accommodated in a housing. The electric wire with a terminal has a terminal metal fitting connected to the end of the electric wire, and a load may be applied from the electric wire to the terminal metal fitting. For example, in an electric wire with a terminal, the electric wire is pulled out of the housing, and when a load (e.g., a tensile load in the axial direction or a torsional load around the axis, etc.) is applied to the electric wire outside the housing, the load may be transmitted to the terminal metal fitting. In addition, for example, in some electric wires with terminals, the electric wire is bent and routed in the housing, and the reaction force of the bent part of the electric wire may be transmitted as a load to the terminal metal fitting. In a connector, if an excessive load is applied from the electric wire to the terminal metal fitting, it is not desirable in terms of ensuring the durability of the electric wire with a terminal. For this reason, in conventional connectors, the electric wire pulled out from the terminal metal fitting is held in the housing to prevent the input of an overload from the electric wire to the terminal metal fitting. For example, the following Patent Document 1 discloses a connector provided with a holding member for holding the electric wire. The holding member inserts the electric wire between a pair of pressure contact blades while cutting through the insulation displacement coating, and holds the electric wire with each of the pressure contact blades.

[0003] [Patent Document 1] JP 2003-331982 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, conventional connectors require a retaining member with a pair of pressure-connecting blades to be provided for each of a plurality of electric wires with terminals, and there is still room for improvement in preventing the input of excessive load to each terminal fitting.

[0005] SUMMARY OF THE PRESENT EMBODIMENTS An object of the present invention is to provide a connector that is capable of providing a suitable function for preventing the input of an overload to a terminal fitting. [Means for solving the problem]

[0006] The present invention is characterized by comprising: a plurality of electric wires with terminals, each having a terminal fitting connected to an end of the electric wire; a housing that accommodates the plurality of electric wires with terminals and allows each of the electric wires to be pulled outward from a first opening; a cover that is assembled to the housing and closes a second opening of the housing; and a wire locking mechanism that bundles and restrains ends of each of the plurality of electric wires with terminals within the housing by applying an external pressure and locks the ends of each of the electric wires to the housing and the cover in a restraining position. Effect of the Invention

[0007] The wire locking mechanism of the connector according to the present invention locks the ends of the electric wires to the housing and the cover at the restraining position, so that when a tensile load is applied to the electric wires outside the housing, the tensile load is less likely to be transmitted to the terminal fittings than at the restraining position. In addition, the wire locking mechanism bundles the ends of the electric wires together with the coverings in close contact with each other, generating a large frictional force between the ends of the electric wires. Therefore, the wire locking mechanism can suppress rotation around the axis at the ends of the electric wires, so that the transmission of rotational torque from the ends of the electric wires to the terminal fittings can be suppressed. In this way, the connector according to the present invention can suppress the transmission of tensile loads and rotational torque from the ends of the electric wires to the terminal fittings, and has a suitable function of suppressing the input of overloads to the terminal fittings. Therefore, the connector according to the present invention can maintain the quality of the electrical connection between the ends of the electric wires and the terminal fittings.

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a connector according to the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to this embodiment.

[0010] [Embodiment] One embodiment of a connector according to the present invention will be described with reference to FIGS.

[0011] Reference numeral 1 shown in FIGS. 1 to 3 denotes a connector of this embodiment.

[0012] The connector 1 includes a plurality of electric wires 10 with terminals (FIGS. 1 and 2).

[0013] The electric wire with terminal 10 includes an electric wire 20 and a terminal fitting 30 connected to an end of the electric wire 20 (FIGS. 1, 2, and 4). The electric wire 20 and the terminal fitting 30 may be connected in any manner. The terminal fitting 30 shown here is provided with a terminal connection portion 31 that physically and electrically connects the electric wire 20 to a mating terminal fitting (not shown), and is provided with two electric wire connection portions 32 each having a pair of pressure-connecting blades 32a (FIGS. 1, 2, and 4). The end of the electric wire 20 is inserted between the pair of pressure-connecting blades 32a in each of the electric wire connection portions 32. At the end of the electric wire 20, the pair of pressure-connecting blades 32a cuts through the coating 21, while the pair of pressure-connecting blades 32a bites into the core wire 22, thereby physically and electrically connecting the core wire 22 to the terminal fitting 30 (FIGS. 1, 2, and 4). The core wire 22 may be a columnar solid-wire conductor, or may be a stranded wire formed by bundling a plurality of wires.

[0014] The connector 1 shown here is equipped with a cable 10A (a so-called VVF cable: vinyl insulated vinyl sheathed flat-type cable) in which a plurality of electric wires 20 are arranged in a direction perpendicular to the axis and housed in a cylindrical sheath 25, with the ends of the electric wires 20 protruding from the openings at the ends of the sheath 25 (FIGS. 1, 2, and 4 to 6). Here, three electric wires 20 are housed in the sheath 25.

[0015] The connector 1 includes a housing 40 that accommodates a plurality of electric wires 10 with terminals (FIGS. 1 to 3).

[0016] The housing 40 is made of an insulating material such as synthetic resin. The housing 40 has a first opening 40a through which the electric wires 20 are pulled out, and a second opening 40b that is perpendicular to the first opening 40a and connected to the first opening 40a (FIGS. 1 and 7). In the housing 40, a notch 40a that forms the first opening 40a together with a cover 50 (described later) is provided. 1In the housing 40, the notch 40a is formed (FIGS. 1 and 7). 1 The second opening 40b serves as an insertion port for accommodating the electric wire 20 and the terminal fitting 30 inside the housing 40. The second opening 40b allows the end of the electric wire 20 and the terminal fitting 30 inside the housing 40 to be exposed.

[0017] The housing 40 has a cylindrical fitting portion 41 for accommodating the terminal connection portion 31, and an accommodating portion 42 for accommodating the end of the electric wire 20 and the electric wire connection portion 32 (FIGS. 1 to 3 and 7). 1 The first opening 40a (notch 40a) and the second opening 40b are formed in the housing 42. Therefore, the second opening 40b can expose the end of the electric wire 20 and the electric wire connection portion 32 in the housing 42. Here, the fitting portion 41 is formed in a square tube shape. Here, the housing 42 is formed to have a rectangular housing chamber, and the first opening 40a (notch 40a 1 ) and the second opening 40b form a rectangular opening.

[0018] An end of the cable 10A is accommodated in this housing 40. Here, the ends of the electric wires 20, the terminal fittings 30, and the sheaths 25 are accommodated in the housing 40, and the electric wires 20 are pulled out together with the sheaths 25 from the first openings 40a. In the accommodating portion 42, partition walls 43 are provided between the terminal fittings 30 (FIGS. 1 and 7).

[0019] Here, in the electric wire with terminal 10, the distance between adjacent terminal fittings 30 is regulated by law. For this reason, in the accommodating portion 42, the ends of the electric wires 20 of each electric wire with terminal 10 are appropriately bent in order to ensure the regulated distance between the adjacent terminal fittings 30. Here, in the arrangement direction of each electric wire 20, the end of the electric wire 20 arranged in the center is not bent in the arrangement direction, but the ends of each electric wire 20 at both ends are bent in a crank shape in the arrangement direction. In other words, the ends of each electric wire 20 at both ends have bent portions 23 bent in a crank shape in the arrangement direction of each electric wire 20 (FIGS. 1, 2, 4, and 6).

[0020] The three electric wires 20 are each bent into a crank shape in a direction intersecting the arrangement direction by being restrained by an electric wire locking mechanism 60 described later. Therefore, an end of the central electric wire 20 has a bent portion 24 bent into a crank shape in a direction intersecting the arrangement direction (FIGS. 1, 2, 4, and 6). Moreover, at the ends of each of the electric wires 20 on both ends, the bent portions 23 are further bent in a direction intersecting the arrangement direction.

[0021] The connector 1 includes a cover 50 that is attached to the housing 40 to close the second opening 40b (FIGS. 1 to 3).

[0022] The cover 50 is made of an insulating material such as synthetic resin, etc. The cover 50 is provided with a rectangular flat cover body 51 that closes the second opening 40b (FIGS. 1 to 3).

[0023] The cover 50 is inserted into the notch 40a of the housing 40. 1 The notch 40a is spaced apart from the bottom of the 1 The cover body 51 has a fitting portion 52 that fits into the bottom of the cover body 51 and forms a through-hole shaped first opening 40a between itself and the bottom of the fitting portion 52 (FIG. 2). The fitting portion 52 protrudes in a rectangular plate shape from the cover body 51. Therefore, the first opening 40a is formed in a rectangular through-hole shape.

[0024] The cover 50 has a wire pressing portion 53 for each electric wire 20, which is pressed against an end of the electric wire 20 and directly or indirectly sandwiches the end of the electric wire 20 between the housing 40 (FIGS. 1 and 2). The wire pressing portion 53 protrudes in a rectangular plate shape from the cover body 51. The wire pressing portion 53 shown here is pressed against the end of the electric wire 20 between two pairs of pressure contact blades 32a, and indirectly sandwiches the end of the electric wire 20 between the housing 40 via the terminal fittings 30.

[0025] In this connector 1, the input of load from the electric wires 20 to the terminal fittings 30 is suppressed by holding the ends of the electric wires 20 inside the housing 40. Therefore, this connector 1 is provided with an electric wire locking mechanism 60 that bundles and restrains the ends of the electric wires 20 of the multiple electric wires with terminals 10 inside the housing 40 by applying pressure from the outside, and locks the ends of the electric wires 20 to the housing 40 and the cover 50 at the restraining position (FIGS. 1, 2, and 4 to 7).

[0026] The wire locking mechanism 60 of the present embodiment includes an annular restraining member 61 that presses the ends of the wires 20 from the outside in the housing 40 to bundle and restrain them. The restraining member 61 is attached to the periphery of the first opening 40a (i.e., the notch 40a of the housing 40). 1 The peripheral portion of the cover 50 engages with the fitting portion 52 of the cover 50 (FIGS. 1, 2, and 4 to 7). The wire pressing portion 53 described above is provided on the terminal fitting 30 side of the restraining member 61, and directly or indirectly holds the wire 20 routed on the terminal fitting 30 side of the restraining member 61 between the housing 40 and the wire pressing portion 53.

[0027] Specifically, the restraining member 61 is a crimping member that crimps the ends of the electric wires 20 to bundle them together and tightly attaches the coverings 21 of the ends of the electric wires 20 to each other, thereby restraining the ends of the electric wires 20 from shifting. For example, the restraining member 61 may be a metal C-shaped member such as a T-shaped connector, a cable tie, a hose band, or the like.

[0028] The electric wire locking mechanism 60 (restraint member 61) shown here applies pressure from above the sheath 25, disrupting the arrangement of the ends of each electric wire 20 inside the sheath 25 and bundling and restraining them together (FIGS. 1, 2, and 4 to 7).

[0029] This wire locking mechanism 60 (restraint member 61) locks the ends of each wire 20 to the housing 40 and the cover 50 at the restraining position, so that when a tensile load is input to the wire 20 outside the housing 40, the tensile load is less likely to be transmitted to the terminal fitting 30 side than the restraining position.

[0030] In addition, the electric wire locking mechanism 60 (restraint member 61) bundles the ends of the electric wires 20 together with the coverings 21 in close contact with each other, generating a large frictional force between the ends of the electric wires 20. Therefore, the electric wire locking mechanism 60 (restraint member 61) can suppress rotation around the axis at the end of each electric wire 20, thereby suppressing transmission of rotational torque from the end of the electric wire 20 to the terminal fitting 30. The electric wire locking mechanism 60 (restraint member 61) shown here also generates a large frictional force between the end of each electric wire 20 and the sheath 25. Therefore, the electric wire locking mechanism 60 (restraint member 61) can suppress relative rotation around the axis of the end of each electric wire 20 with respect to the sheath 25, thereby suppressing transmission of rotational torque from the end of the electric wire 20 to the terminal fitting 30.

[0031] In addition, the ends of the electric wires 20 at both ends are bent in a crank shape in the arrangement direction of the electric wires 20, and generate a tensile load toward the first opening 40a side compared to the end of the central electric wire 20. However, this electric wire locking mechanism 60 (restraint member 61) bundles the ends of the electric wires 20 together with the coverings 21 in close contact with each other on the first opening 40a side from the bending position (i.e., the bent portion 23), generating a large frictional force between the ends of the electric wires 20. The electric wire locking mechanism 60 (restraint member 61) shown here further generates a large frictional force between the ends of the electric wires 20 and the sheath 25 on the first opening 40a side from the bending position (i.e., the bent portion 23). Therefore, this electric wire locking mechanism 60 (restraint member 61) can suppress the tensile load toward the first opening 40a side generated at the ends of the electric wires 20 at both ends.

[0032] In this way, the connector 1 of this embodiment can suppress the transmission of tensile load and rotational torque from the end of the electric wire 20 to the terminal fitting 30, and has a suitable function of preventing the input of overload to the terminal fitting 30. Therefore, the connector 1 of this embodiment can maintain the quality of the electrical connection between the end of the electric wire 20 and the terminal fitting 30. Note that the connector 1 of this embodiment may be provided with electric wire locking mechanisms 60 (restraint members 61) at multiple locations in order to improve the function of preventing the input of overload.

[0033] [Variations] The connector 2 of this modification is the connector 1 of the above-described embodiment, in which the electric wire locking mechanism 60 is changed to the following electric wire locking mechanism 160 (FIGS. 8 and 9). Therefore, in the following description of this modification, the same reference numerals as those in the embodiment denote the same parts, portions, etc. as those in the embodiment. Also, descriptions that overlap with the embodiment will be omitted here.

[0034] In the connector 2 of this modification, the housing 40 of the embodiment is replaced with the housing 140 described below, and the cover 50 of the embodiment is replaced with the cover 150 described below (FIGS. 8 and 9). The housing 140 and the cover 150 of this modification are molded from an insulating material such as synthetic resin, like the housing 40 and the cover 50 of the embodiment.

[0035] The housing 140 of this modification has a fitting portion 141 and a storage portion 142 similar to the housing 40 of the embodiment (FIGS. 8 to 10). The storage portion 142 of this modification has a first opening 140a (notch 140a) similar to the storage portion 42 of the embodiment. 1 ), a second opening 140b and a partition wall 143 (FIG. 8).

[0036] The cover 150 of this modification has a cover body 151 similar to the cover 50 of the embodiment (FIGS. 8 to 10). However, the cover 150 of this modification does not have the fitting portion 52 and the electric wire pressing portion 53 of the cover 50 of the embodiment, but may have the same fitting portion 52 and electric wire pressing portion 53.

[0037] In the electric wire locking mechanism 160 of this modification, a first clamping portion 144 provided on the housing 140 and a second clamping portion 152 provided on the cover 150 have the same function as the electric wire locking mechanism 60 (restraint member 61) of the embodiment (FIGS. 8 and 9). In the electric wire locking mechanism 160, an end of each electric wire 20 is clamped and pressurized by the first clamping portion 144 and the second clamping portion 152 in the housing 140, and the ends of each electric wire 20 are bundled and restrained by the pressure from the first clamping portion 144 and the second clamping portion 152, and the ends of each electric wire 20 are locked to the housing 140 and the cover 150.

[0038] The electric wire locking mechanism 160 shown here clamps and pressurizes the end of the cable 10A from above the sheath 25 between a first clamping portion 144 and a second clamping portion 152, and the pressing force from the first clamping portion 144 and the second clamping portion 152 bundles and restrains the ends of each electric wire 20 inside the sheath 25.

[0039] Specifically, the housing 140 shown here has a semicircular groove or notch in a protruding portion 145 protruding from the bottom wall of the accommodating portion 142, and this groove or notch is used as the first clamping portion 144 (FIG. 8). The cover 150 shown here has a semicircular groove or notch in a protruding portion 153 protruding from a cover body 151, and this groove or notch is used as the second clamping portion 152 (FIG. 9). The first clamping portion 144 and the second clamping portion 152 form a circular through hole when the housing 140 and the cover 150 are in a completed assembled state. The ends of the electric wires 20 are bundled together, so that all circles in a cross section perpendicular to the axis at the restraining position are in contact with each other. The circular through hole formed by the first clamping portion 144 and the second clamping portion 152 is a circle having a smaller diameter than a circle circumscribing all the circles.

[0040] Since the electric wire locking mechanism 160 of this modification has a clamping structure using the first clamping portion 144 and the second clamping portion 152, when the housing 140 and the cover 150 are assembled, the first clamping portion 144 and the second clamping portion 152 clamp the ends of the electric wires 20 from above the sheath 25. Therefore, it is preferable that the cable 10A of this modification has a deformed portion 126 in which the positions at which the electric wires 20 are clamped by the first clamping portion 144 and the second clamping portion 152 are deformed into a circular or polygonal shape in advance, and the arrangement of the ends of the electric wires 20 in the sheath 25 is disrupted (FIGS. 8, 9, and 11). The deformed portion 126 is formed, for example, by applying pressure to deform a part of the end of the cable 10A using a jig or tool using a circular or polygonal die.

[0041] In connector 2 of this modification, cable 10A is accommodated in housing 140 with deformation portion 126 fitted into first clamping portion 144, and cover 150 is attached to housing 140. As a result, in this connector 2, deformation portion 126 is sandwiched and pressurized from above sheath 25 between first clamping portion 144 and second clamping portion 152, and the terminals of each electric wire 20 in sheath 25 are bundled and restrained together by the pressure from first clamping portion 144 and second clamping portion 152.

[0042] The wire locking mechanism 160 of this modified example, like the wire locking mechanism 60 (restraint member 61) of the embodiment, locks the ends of each wire 20 to the housing 140 and the cover 150 at the restraining position, so that when a tensile load is input to the wire 20 outside the housing 140, the tensile load is less likely to be transmitted to the terminal fitting 30 side than the restraining position.

[0043] Moreover, the electric wire locking mechanism 160 of this modification, like the electric wire locking mechanism 60 (restraint member 61) of the embodiment, bundles the ends of the electric wires 20 together with the coverings 21 in close contact with each other, and generates a large frictional force between the ends of the electric wires 20. Therefore, this electric wire locking mechanism 160 can suppress rotation around the axis at the end of each electric wire 20, and can suppress transmission of rotational torque from the end of the electric wire 20 to the terminal fitting 30. The electric wire locking mechanism 160 shown here further generates a large frictional force between the end of each electric wire 20 and the sheath 25, like the electric wire locking mechanism 60 (restraint member 61) of the embodiment. Therefore, this electric wire locking mechanism 160 can suppress relative rotation around the axis of the end of each electric wire 20 with respect to the sheath 25, and can suppress transmission of rotational torque from the end of the electric wire 20 to the terminal fitting 30.

[0044] Also in the connector 2 of this modification, the ends of the electric wires 20 at both ends are bent in a crank shape in the arrangement direction of the electric wires 20, and generate a tensile load toward the first opening 140a side compared to the end of the central electric wire 20. However, the electric wire locking mechanism 160 of this modification, like the electric wire locking mechanism 60 (restraint member 61) of the embodiment, bundles the ends of the electric wires 20 together with the coverings 21 in close contact with each other on the first opening 140a side from the bending position (i.e., the bent portion 23), and generates a large frictional force between the ends of the electric wires 20. The electric wire locking mechanism 160 shown here, like the electric wire locking mechanism 60 (restraint member 61) of the embodiment, further generates a large frictional force between the ends of the electric wires 20 and the sheath 25 on the first opening 140a side from the bending position (i.e., the bent portion 23). Therefore, the electric wire locking mechanism 160 can keep low the tensile load toward the first opening 140a generated at the terminals of the electric wires 20 at both ends.

[0045] In this manner, in the connector 2 of this modification, like the connector 1 of the embodiment, the transmission of tensile load and rotational torque from the end of the electric wire 20 to the terminal fitting 30 can be suppressed, and the connector 2 of this modification has a suitable function of preventing the input of an overload to the terminal fitting 30. Therefore, the connector 2 of this modification can maintain the quality of the electrical connection between the end of the electric wire 20 and the terminal fitting 30. Note that the connector 2 of this modification may be provided with electric wire locking mechanisms 160 (combinations of a pair of a first clamping portion 144 and a second clamping portion 152) at multiple locations in order to improve the function of preventing the input of an overload.

[0046] Here, in the connector 2 of this modification, a plurality of protrusions that bite into the sheath 25 may be provided on the semicircular arc-shaped surface of both or either of the first clamping portion 144 and the second clamping portion 152. The plurality of protrusions may be, for example, a plurality of linear protrusions arranged in the axial direction along the circumferential direction of the arc-shaped surface, or a plurality of dot-like protrusions formed by embossing the arc-shaped surface. As a result, in the connector 2 of this modification, the frictional force between both or either of the first clamping portion 144 and the second clamping portion 152 and the sheath 25 can be increased, so that the transmission of the tensile load and the transmission of the rotational torque from the end of the electric wire 20 to the terminal fitting 30 can be further suppressed. In this example, a plurality of linear protrusions 144a are provided on the first clamping portion 144 (FIG. 8).

[0047] Here, in the connector 2 of this modification, the end of the cable 10A is provided with a deformation portion 126 in advance, but by accommodating the cable 10A in the housing 140 in the direction shown in the figure, it is not necessary to provide the deformation portion 126. That is, in this connector 2, the arrangement direction of each electric wire 20 is aligned with the assembly direction of the housing 140 and the cover 150, and in this state, the end of the cable 10A is inserted into the first clamping portion 144 (FIG. 12). As a result, in the connector 2 of this modification, when the cover 150 is assembled to the housing 140, the second clamping portion 152 crushes the end of the cable 10A between the first clamping portion 144 and the second clamping portion 152, thereby destroying the arrangement of the ends of the electric wires 20 in the sheath 25. In this connector 2, when the assembly of the housing 140 and the cover 150 is completed, the terminals of the respective electric wires 20 are clamped and pressurized from above the sheath 25 between the first clamping portion 144 and the second clamping portion 152, and the terminals of the respective electric wires 20 in the sheath 25 are bundled and restrained together by the pressure from the first clamping portion 144 and the second clamping portion 152. The connector 2 of this modified example can thus achieve the same effect as the previous example by using the electric wire locking mechanism 160 (the first clamping portion 144 and the second clamping portion 152) even without providing the deforming portion 126 in the cable 10A.

A plurality of terminal-attached electric wires each having a terminal metal fitting connected to an end of the electric wire; a housing that accommodates a plurality of the electric wires with terminals and allows each of the electric wires to be drawn outward from a first opening; a cover that is attached to the housing to close the second opening of the housing; an electric wire locking mechanism that bundles and holds ends of each of the plurality of electric wires with terminals together in the housing by applying a pressure from outside and locks the ends of each of the electric wires to the housing and the cover at a holding position; A connector comprising:

2. 2. The connector as described in claim 1, wherein the wire locking mechanism includes an annular restraining member that applies pressure from the outside to the ends of each of the wires within the housing to bundle and restrain them, and the restraining member is locked at a peripheral portion of the first opening.

3. The connector as described in claim 2, characterized in that the cover has a wire pressing portion for each of the electric wires, which is pressed against the end of the electric wire on the terminal fitting side rather than the restraining member, and directly or indirectly clamps the end of the electric wire between the housing and the cover.

4. 2. The connector as described in claim 1, wherein the wire locking mechanism clamps and pressurizes the ends of each of the electric wires within the housing with a first clamping portion provided on the housing and a second clamping portion provided on the cover, and bundles and restrains the ends of each of the electric wires together with the pressure from the first clamping portion and the second clamping portion, thereby locking the ends of each of the electric wires to the housing and the cover.

5. a cable in which a plurality of the electric wires are arranged in a direction perpendicular to an axis and housed in a cylindrical sheath, and an end of each of the electric wires protrudes from an opening at an end of the sheath, 5. A connector as described in claim 1, 2, 3 or 4, characterized in that the wire locking mechanism applies pressure from above the sheath, disrupting the orthogonal arrangement of the ends of each of the wires in the sheath and bundling and restraining them together.
