Description

[Technical Field]

[0001] The present invention relates to a joint connector and a method for manufacturing a joint connector. [Background technology]

[0002] 2. Description of the Related Art Joint connectors have been proposed for use in connecting a plurality of electric wires extending from a plurality of devices to one another.

[0003] For example, one conventional joint connector includes a bus bar having a plurality of pin terminals for connecting to mating terminals of a mating connector, an inner housing for holding the bus bar, and an outer housing for accommodating a ferrite plate for noise reduction and to which the inner housing is attached. The pin terminals extend forward in the assembly direction of the inner housing and the outer housing, and are connected to each other via a connecting portion at the rear of the assembly direction. In other words, the pin terminals are electrically conductive to each other via the connecting portion (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Japanese Patent Publication No. 2022-006405 Summary of the Invention [Problem to be solved by the invention]

[0005] In the conventional joint connector described above, the ferrite core (magnetic member) for noise reduction is housed inside the inner housing with the pin terminal of the bus bar passing through the ferrite core. Because the ferrite core is housed in this manner, it is difficult to add or remove the ferrite core after manufacturing the joint connector. Therefore, conventional joint connectors are generally manufactured as dedicated products according to specifications and are not very versatile.

[0006] An object of the present invention is to provide a joint connector that is highly versatile and a method for manufacturing such a joint connector. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the joint connector and the manufacturing method of the joint connector according to the present invention are characterized as follows.

[0008] a housing having a mating recess into which a mating connector is mated; a joint terminal accommodated in the housing, the joint terminal including: a bus bar portion for connecting circuits belonging to the mating connector; and a plurality of terminal portions disposed in the fitting recess, extending toward the mating connector, and connected to the bus bar portion; at least one magnetic member for noise reduction accommodated in the housing corresponding to at least one of the plurality of terminal portions; A joint connector comprising: Each of the plurality of terminal portions is a bent portion bent in a shape that is convex in a direction different from the direction of the terminal portion, between a tip end portion and a base end portion of the terminal portion; Each of the magnetic members is The terminal has a hole through which the bent portion of the corresponding terminal can be inserted, and is accommodated in the housing with the bent portion inserted into the hole. It is a joint connector.

[0009] A method for manufacturing a joint connector in which a joint terminal is accommodated in a housing, comprising: The housing includes: A mating recess is provided for mating with the mating connector. The joint terminal is a bus bar portion for connecting circuits belonging to the mating connector together; and a plurality of terminal portions disposed in the fitting recess, extending in a direction toward the mating connector, and connected to the bus bar portion, Each of the plurality of terminal portions is a bent portion bent in a shape that is convex in a direction different from the direction of the terminal portion, between a tip end portion and a base end portion of the terminal portion; The manufacturing method includes: determining whether or not at least one magnetic member for noise reduction is provided corresponding to at least one of the plurality of terminal portions; a step of accommodating the joint terminal in the housing so that the tip end portion of each of the plurality of terminal portions is positioned in the fitting recess of the housing; When the magnetic member is provided, the magnetic member is accommodated in the housing in a state in which the bent portion of the corresponding terminal portion is inserted into a hole portion of the magnetic member. It is a manufacturing method for joint connectors. [Effects of the Invention]

[0010] According to the joint connector of the present invention, the terminal portion of the joint terminal has a bent portion bent into a convex shape in a direction different from the direction toward the mating connector, between the distal end and proximal end of the terminal portion. The noise-reducing magnetic member (e.g., a ferrite core) has a hole through which the bent portion can be inserted. Therefore, after assembling the joint terminal so that the distal end of the terminal portion of the joint terminal is positioned in the mating recess of the housing, the magnetic member can be attached so that the bent portion of at least one terminal portion (e.g., the terminal to which the magnetic member should be attached according to the specifications) fits into the hole of the magnetic member. In other words, after accommodating the joint terminal in the housing, magnetic members can be selectively attached in necessary locations depending on the circuit characteristics and required specifications. Therefore, the housing and joint terminal can be standardized regardless of specifications. Furthermore, even after the joint connector is manufactured, magnetic members can be added or removed as needed. Therefore, the joint connector of the present invention is highly versatile.

[0011] Furthermore, as another effect, since the bent portion of the terminal portion of the joint terminal is housed in the hole of the magnetic member, the noise reduction effect of the magnetic member is exerted at both the distal end and proximal end of the bent portion, thereby improving the noise reduction effect of the joint connector of the present invention.

[0012] According to the manufacturing method for a joint connector of the present invention, the terminal portion of the joint terminal included in the manufactured joint connector has a bent portion bent into a convex shape in a direction different from the direction toward the mating connector, between the distal end and proximal end of the terminal portion. The noise-reducing magnetic member (e.g., a ferrite core) has a hole through which the bent portion can be inserted. Therefore, after assembling the joint terminal so that the distal end of the terminal portion of the joint terminal is positioned in the mating recess of the housing, the magnetic member can be attached so that the bent portion of at least one terminal portion (e.g., the terminal to which the magnetic member should be attached according to the specifications) fits into the hole of the magnetic member. In other words, after accommodating the joint terminal in the housing, magnetic members can be selectively assembled in necessary locations depending on the circuit characteristics and required specifications. Therefore, the housing and joint terminal can be standardized regardless of specifications. Furthermore, even after the joint connector is manufactured, magnetic members can be added or removed as needed. Therefore, the manufacturing method for a joint connector of the present invention can manufacture a joint connector with excellent versatility.

DETAILED DESCRIPTION OF THE INVENTION

[0015] <Embodiment> A joint connector 1 according to an embodiment of the present invention will be described with reference to the drawings. For ease of explanation, "front," "rear," "left," "right," "upper," and "lower" are defined below as shown in FIG. 1 and elsewhere. The "front-rear direction," "left-right direction," and "up-down direction" are perpendicular to one another. The front-rear direction coincides with the mating direction of the joint connector 1 and a mating connector (not shown).

[0016] 1 to 8, the joint connector 1 according to this embodiment has a housing 10, a pair of upper and lower joint terminals 20 housed in the housing 10, and a plurality of (four in this example) ferrite cores 30 housed in the housing 10 corresponding to a plurality of terminal portions 22 (eight in total in two rows, upper and lower) of the pair of upper and lower joint terminals 20. The plurality of ferrite cores 30 are attached according to the specifications of the joint connector 1.

[0017] A mating connector (not shown) is fitted and connected to the joint connector 1 from the front side. When connected to the mating connector, the joint connector 1 functions to form a joint circuit of a wire harness that is routed in a vehicle. The configuration of the members that make up the joint connector 1 will be explained below in order.

[0018] First, we will explain the joint terminal 20. The pair of upper and lower joint terminals 20 have the same shape and are housed in the housing 10 in upside-down orientations, as shown in Figures 1 and 2. The joint terminal 20 is made of a conductive metal plate made of, for example, copper, copper alloy, aluminum, aluminum alloy, etc., and is formed by press working or the like.

[0019] 1 and 2, the joint terminal 20 integrally includes a bus bar portion 21 and a plurality of (four in this example) terminal portions 22. The bus bar portion 21 functions to connect a plurality of circuits belonging to a mating connector (not shown), and the terminal portions 22 function to connect to mating terminals (female terminals) belonging to the mating connector (not shown).

[0020] The busbar portion 21 has a generally rectangular, flat plate shape extending in the left-right direction. The four terminal portions 22 extend in elongated shapes at intervals in the left-right direction from the rear end edge of the busbar portion 21. Each terminal portion 22 is composed of a bent portion 23 that extends in the up-down direction while bending in a U-shape that convex rearward from the rear end edge of the busbar portion 21, and a connecting portion 24 that extends linearly forward from the tip end (facing forward) of the bent portion 23. The upper joint terminal 20 is accommodated in the housing 10 with the connecting portion 24 facing downward relative to the busbar portion 21, and the lower joint terminal 20 is accommodated in the housing 10 with the connecting portion 24 facing upward relative to the busbar portion 21. In this way, terminal portion 22 has a bent portion 23 bent into a convex shape in a direction (rearward) different from the direction in which connection portion 24 extends (forward), and is located between the tip portion of terminal portion 22 (the tip portion of connection portion 24) and the base portion of terminal portion 22 (the base portion of bent portion 23).

[0021] Next, the housing 10 will be described. The housing 10 is an insulating resin molded body and is composed of a housing main body 11 and a cover portion 12. The housing main body 11 has a generally rectangular cylindrical shape extending in the front-to-rear direction. The cover portion 12 has a generally rectangular flat plate shape that corresponds to the shape of the rear end opening of the housing main body 11, and is connected to the upper edge that defines the rear end opening via a hinge portion 13 so that the rear end opening can be opened and closed.

[0022] A terminal holding portion 15 is provided in a position rearward of the center in the front-rear direction in the hollow portion of the housing main body 11 so as to divide the hollow portion in half in the front-rear direction (see FIG. 8). The terminal holding portion 15 functions to hold a pair of upper and lower joint terminals 20. The terminal holding portion 15 is formed with a pair of upper and lower press-fitting holes 16 into which the busbar portions 21 of the pair of upper and lower joint terminals 20 are press-fitted, and a plurality of (a total of eight in two rows, upper and lower) insertion holes 17 into which a plurality of (a total of eight in two rows, upper and lower) connecting portions 24 of the pair of upper and lower joint terminals 20 are inserted (see FIG. 8).

[0023] A mating recess 14, recessed rearward and open forward, is defined in front of the terminal holding portion 15 in the hollow portion of the housing body 11 (see FIGS. 7 and 8). A terminal holding portion (not shown) of a mating connector is fitted into the mating recess 14. A plurality of (four in this example) ferrite core recesses 18, recessed forward and open rearward, are defined in the rear of the terminal holding portion 15 in the hollow portion of the housing body 11 and aligned in the left-right direction (see FIGS. 1 and 8). A ferrite core 30 is housed in each ferrite core recess 18.

[0024] As shown in Figure 6, the cover portion 12 of the housing 10 has multiple (four in this example) openings 19 formed in a line in the left-right direction, penetrating the cover portion 12 in the thickness direction (front-to-back direction when the cover portion 12 is closed) to correspond to the multiple (four) ferrite cores 30 housed in the housing 10.

[0025] Next, the ferrite core 30 will be described. The ferrite core 30 is disposed in the housing 10 corresponding to the terminal portions 22 of the joint terminals 20, thereby reducing noise generated at the terminal portions 22. The ferrite core 30 is made of a magnetic material and, as shown in FIGS. 1 and 3, has a generally rectangular, flat plate shape and an approximately H-shaped overall configuration. The ferrite core 30 has a pair of upper and lower notches 31 formed therethrough in the thickness direction (front-rear direction) corresponding to the pair of upper and lower joint terminals 20. The notches 31 have a U-shape. The upper notch 31 is formed on the upper surface of the ferrite core 30, is recessed downward, and is open upward. The lower notch 31 is formed on the lower surface of the ferrite core 30, is recessed upward, and is open downward. The bent portions 23 of the pair of upper and lower joint terminals 20 are inserted into the pair of upper and lower notches 31 (see FIGS. 5 and 8). The configuration of the members constituting the joint connector 1 has been described above.

[0026] Next, a description will be given of the procedure for assembling the joint connector 1. To assemble the joint connector 1, first, as shown in Fig. 4, a pair of upper and lower joint terminals 20 are assembled to the terminal holding portion 15 of the housing 10. Specifically, the pair of upper and lower joint terminals 20 are assembled from the rear side to the terminal holding portion 15 of the housing 10 with the cover portion 12 in the open state, such that the pair of upper and lower bus bar portions 21 are press-fitted into the pair of upper and lower press-fit holes 16, respectively, and the multiple (eight in total in two rows, upper and lower) connection portions 24 of the pair of upper and lower joint terminals 20 are inserted into the multiple (eight in total in two rows, upper and lower) insertion holes 17, respectively. When the upper and lower pair of joint terminals 20 are completely assembled into the housing 10, each of the four "upper and lower pair of bending portions 23" aligned in the left-right direction in the upper and lower pair of joint terminals 20 is positioned within a corresponding one of the four ferrite core recesses 18 aligned in the left-right direction (see Figures 4 and 8), and the tip of each of the multiple connection portions 24 of the upper and lower pair of joint terminals 20 is positioned within the mating recess 14 (see Figures 7 and 8).

[0027] Next, as shown in FIG. 5 , each of the four ferrite cores 30 is accommodated in a corresponding one of the four ferrite core recesses 18 aligned in the left-right direction. Specifically, each ferrite core 30 is accommodated in the corresponding ferrite core recess 18 from the rear side so that the "pair of upper and lower bent portions 23" located in the corresponding ferrite core recess 18 are inserted into the pair of upper and lower cutout portions 31, respectively. In this example, the cutout portions 31 having an open hole shape are used as the "holes" of the ferrite core 30, which makes it easier to assemble the ferrite core 30 to the terminal portion 22 of the joint terminal 20 compared to when a "hole" having a closed hole shape is used. When the ferrite core 30 is completely accommodated in the ferrite core recess 18, as shown in Figure 8, the bent portion 23 of the joint terminal 20 is accommodated in the notch portion 31 of the ferrite core 30, and the noise reduction effect of the ferrite core 30 is exerted in both the tip end portion and the base end portion of the bent portion 23.

[0028] In the present embodiment, the joint connector 1 is designed to have the ferrite cores 30 attached to all four "pairs of upper and lower bent portions 23 (terminal portions 22)" aligned in the left-right direction. As a result, as shown in FIG. 5, all four ferrite core recesses 18 house ferrite cores 30. In contrast, when the joint connector 1 is designed to have the ferrite cores 30 attached to only some of the four "pairs of upper and lower bent portions 23 (terminal portions 22)" aligned in the left-right direction, the ferrite cores 30 are housed in only some of the four ferrite core recesses 18. For example, in the example shown in FIG. 9, the joint connector 1 is designed to have the ferrite cores 30 attached to only two "pairs of upper and lower bent portions 23 (terminal portions 22)" aligned in the left-right direction, which are the central two "pairs of upper and lower bent portions 23 (terminal portions 22)" of the four "pairs of upper and lower bent portions 23 (terminal portions 22)" aligned in the left-right direction. As a result, the ferrite cores 30 are housed in only the central two ferrite core recesses 18 of the four ferrite core recesses 18. Furthermore, when a joint connector 1 is adopted that does not allow the ferrite core 30 to be attached to any of the four "pairs of upper and lower bent portions 23 (terminal portions 22)" aligned in the left-right direction, the ferrite core 30 is not housed in any of the four ferrite core recesses 18, as shown in Figure 10. In this way, the ferrite core 30 is selectively assembled in a required location for each specification of the joint connector 1.

[0029] Next, as shown in Fig. 6, the cover portion 12 of the housing 10 is closed so as to cover the ferrite core 30 assembled to the housing 10. This completes the assembly of the joint connector 1. When the assembly of the joint connector 1 is complete, the presence or absence of a ferrite core 30 can be confirmed for each of the four ferrite core recesses 18 arranged in the left-right direction through the four openings 19 arranged in the left-right direction in the cover portion 12. Furthermore, if necessary, it is also possible to open the cover portion 12 of the housing 10 and then remove the ferrite core 30 from the ferrite core recess 18 in which it is accommodated.

[0030] <Actions and Effects> As described above, according to the joint connector 1 and the manufacturing method for the joint connector 1 of this embodiment, the terminal portion 22 of the joint terminal 20 has a bent portion 23 bent in a convex shape in a direction (rearward) different from the direction (forward) toward the mating connector, between the distal end and proximal end of the terminal portion 22. The noise-reducing magnetic member (ferrite core 30) has a hole 31 (also referred to as a notch 31) through which the bent portion 23 can be inserted. Therefore, after assembling the joint terminal 20 so that the distal end of the terminal portion 22 of the joint terminal 20 is positioned in the fitting recess 14 of the housing 10, the magnetic member 30 can be attached so that the bent portion 23 of at least one terminal portion 22 (e.g., the terminal to which the magnetic member 30 should be attached according to the specifications) fits into the hole 31 of the magnetic member 30. In other words, the magnetic member 30 can be selectively attached to a required location for each specification, allowing the housing 10 and the joint terminal 20 to be standardized regardless of the specifications. Furthermore, the magnetic member 30 can be attached or detached as needed even after the joint connector 1 has been manufactured. Therefore, the joint connector 1 according to this embodiment is highly versatile.

[0031] Furthermore, as another effect, the bent portion 23 of the terminal portion 22 of the joint terminal 20 is housed in the hole 31 of the magnetic member 30, and thus the noise reduction effect of the magnetic member 30 is exerted in both the tip end side portion and the base end side portion of the bent portion 23. Therefore, the joint connector 1 according to this embodiment can improve the noise reduction effect.

[0032] Furthermore, with the joint connector 1 according to this embodiment, the bending portion of the joint terminal 20 can be inserted into the notched hole 31. Compared to when the hole has a closed hole shape, this makes it easier to assemble the magnetic member 30 to the terminal portion 22 of the joint terminal 20, improving workability.

[0033] Furthermore, with the joint connector 1 according to this embodiment, the presence or absence of the magnetic member 30 can be confirmed through the opening 19 of the cover portion 12. This makes it possible to easily check the placement of the magnetic member 30 when manufacturing the joint connector 1 and when using the joint connector 1.

[0034] <Other aspects> It should be noted that the present invention is not limited to the above-described embodiments, and various modifications can be adopted within the scope of the present invention. For example, the present invention is not limited to the above-described embodiments, and modifications, improvements, etc. are possible as appropriate. Furthermore, the material, shape, dimensions, number, location, etc. of each component in the above-described embodiments are arbitrary as long as they can achieve the present invention, and are not limited thereto.

[0035] Here, the features of the embodiments of the joint connector 1 and the manufacturing method for the joint connector 1 according to the present invention described above will be briefly summarized and listed below in [1] to [4].

Therefore, after assembling the joint terminal so that the distal end of the terminal portion of the joint terminal is positioned in the mating recess of the housing, the magnetic member can be attached so that the bent portion of at least one terminal portion (e.g., the terminal to which the magnetic member should be attached according to the specifications) fits into the hole of the magnetic member. In other words, after accommodating the joint terminal in the housing, the magnetic member can be selectively attached in a required location depending on the circuit characteristics and required specifications. Therefore, the housing and joint terminal can be standardized regardless of the specifications. Furthermore, even after the joint connector is manufactured, magnetic members can be added or removed as needed. Therefore, the joint connector having this configuration is highly versatile.

[0038] Furthermore, as another effect, since the bent portion of the terminal portion of the joint terminal is housed in the hole of the magnetic member, the noise reduction effect of the magnetic member is exerted at both the distal end and proximal end of the bent portion, thereby improving the noise reduction effect of the joint connector of this configuration.

The noise-reducing magnetic member (e.g., a ferrite core) has a hole through which the bent portion can be inserted. Therefore, after assembling the joint terminal so that the distal end of the terminal portion of the joint terminal is positioned in the mating recess of the housing, the magnetic member can be attached so that the bent portion of at least one terminal portion (e.g., the terminal to which the magnetic member should be attached according to the specifications) fits into the hole of the magnetic member. In other words, after accommodating the joint terminal in the housing, the magnetic member can be selectively assembled in a required location depending on the circuit characteristics and required specifications. Therefore, the housing and joint terminal can be standardized regardless of the specifications. Furthermore, even after the joint connector is manufactured, magnetic members can be added or removed as needed.
