[Modes for carrying out the invention]
[0010] The embodiments will be described below with reference to the drawings. In the following description, components having the same or similar functions will be denoted by the same reference numerals. The following embodiments are examples of typical embodiments of the present invention, and the scope of the present invention is not limited by these descriptions, and various combinations, modifications, and changes are possible within the scope of the gist of the invention.
[0011] In this application, the X-direction, Y-direction, and Z-direction are defined as follows. The X-direction is the width direction of the terminal housing member 30 described later, and is the direction from the second partition portion 31B toward the first partition portion 31A (see FIG. 1). The Y-direction intersects (for example, is orthogonal to) the X-direction. The Y-direction is the extending direction of the terminal housing member 30 described later, and is the direction from the terminal hole 38 toward the wire opening 39 (see FIG. 1). The Z-direction intersects (for example, is orthogonal to) the X-direction and the Y-direction. The Z-direction is the thickness (height) direction of the terminal housing member 30 described later, and is the direction from the bottom wall portion 32 toward the storage opening 33 (see FIG. 3).
[0012] (Embodiment) FIG. 1 is an exploded perspective view showing a terminal housing unit 10 according to an embodiment of the present invention. The terminal housing unit 10 includes a female terminal (hereinafter abbreviated as "female terminal") 20 to which one end of an electric wire (wire harness) C is connected, and a terminal housing member 30 in which the female terminal (terminal) 20 is mounted.
[0013] [[ID=,10]]The female terminal (terminal) 20 includes a main body portion 21, a tip portion 22 connected to the front portion of the main body portion 21, and an electrical contact portion 23. An electrical contact portion 23 having elasticity (see FIG. 6) protrudes downward from the tip portion 22, and the electric wire C is connected to the rear portion of the main body portion 21. This female terminal 20 is inserted into each terminal storage space of the storage chamber 34 of the terminal housing member 30 in a state before inserting the terminal housing member 30 into a male housing (not shown), and is mounted in the storage chamber 34.
[0014] Further, the main body portion 21 has a portion (hereinafter, recess 24, see FIG. 6) in which the upper surface side of the intermediate portion is recessed in a concave shape. By inserting the female terminal 20 into the terminal housing member 30, this recess 24 is engaged with a terminal fixing portion 37 (see FIG. 6) provided in the storage chamber 34 inside the terminal housing member 30. By this engagement, the female terminal 20 is restrained so as not to move in the front-rear direction.
[0015] As shown in Figures 1 to 6, the terminal storage member 30 comprises a storage chamber 34, a first terminal locking portion (terminal locking portion) 35A, and a second terminal locking portion (terminal locking portion) 35B. The storage chamber 34 has a first partition wall portion 31A, a second partition wall portion 31B facing the first partition wall portion 31A, a bottom wall portion 32, and a storage opening 33. The terminal storage member 30 extends parallel to the longitudinal direction of the female terminal 20.
[0016] The first partition section 31A and the second partition section 31B are partition sections that separate both sides of the female terminal 20. Each of the first partition section 31A and the second partition section 31B may, for example, separate adjacent female terminals 20. Each of the first partition section 31A and the second partition section 31B extends parallel to the longitudinal direction of the female terminal 20 (Y direction in Figure 1). The bottom wall section 32 is connected to one end of the first partition section 31A and to one end of the second partition section 31B that is opposite to the one end of the first partition section 31A. The storage opening 33 is defined by the other end of the first partition section 31A, the other end of the second partition section 31B, the first terminal lock section 35A, and the second terminal lock section 35B. The storage chamber 34 can accommodate the female terminal 20 through the storage opening 33.
[0017] The terminal storage member 30 has three storage chambers 34 formed in the width direction (X direction in Figure 1) for storing multiple female terminals 20 to which electric wires C are connected (for example, three). Each storage chamber 34 has a storage opening 33 formed above the storage chamber 34 in the height direction (Z direction in Figure 1), and one female terminal 20 can be stored through the storage opening 33.
[0018] The terminal storage member 30 is inserted into the insertion chamber (not shown) of the male housing after each female terminal 20 has been stored in its respective storage chamber 34. The terminal storage member 30 is a KitKat-type terminal storage plate in which multiple storage chambers 34, each for storing multiple female terminals 20, are arranged in parallel and connected, and the multiple storage chambers 34 can be cut into the desired number of units for use.
[0019] As shown in Figures 1 and 5, the storage chamber 34 has multiple spaces, each formed by partitioning with a first partition wall 31A and a second partition wall 31B. The storage opening 33 of the storage chamber 34 is provided with a first terminal locking part 35A and a second terminal locking part 35B that protrude from the first partition wall 31A toward the opposing second partition wall 31B of the storage chamber 34 and secure terminals inside the storage chamber 34.
[0020] Each of the first terminal locking portion 35A and the second terminal locking portion 35B is provided only on the first partition wall portion 31A of the first partition wall portion 31A and the second partition wall portion 31B. Each of the first terminal locking portion 35A and the second terminal locking portion 35B may, for example, protrude only from the first partition wall portion 31A toward the second partition wall portion 31B of the first partition wall portion 31A and the second partition wall portion 31B. The second partition wall portion 31B may, for example, have a plane that is aligned with the XY plane across the portion facing the first terminal locking portion 35A and the second terminal locking portion 35B. The storage opening 33 may be narrowed, for example, in the portion where the first terminal locking portion 35A and the second terminal locking portion 35B protrude. In the portions where the first terminal lock portion 35A and the second terminal lock portion 35B protrude, of the pair of contours of the storage opening 33 that extend in the Y direction, for example, the contour on the first partition wall portion 31A side may be recessed in the X direction, while the contour on the second partition wall portion 31B side may not be recessed and may extend in a straight line. That is, in the portions where the first terminal lock portion 35A and the second terminal lock portion 35B protrude, of the pair of contours of the storage opening 33 that extend in the Y direction, only the contour on the first partition wall portion 31A side may be recessed in the X direction.
[0021] The first terminal locking part 35A and the second terminal locking part 35B contact the upper part of the female terminal 20 housed in the storage chamber 34, thereby preventing the female terminal 20 from coming out of each storage chamber 34. The first terminal locking part 35A and the second terminal locking part 35B are made of a flexible material such as plastic that can be bent.
[0022] Each of the first terminal locking section 35A and the second terminal locking section 35B is located on the outside relative to the storage chamber 34 and has an inclined surface that slopes from the first partition wall section 31A toward the second partition wall section 31B toward the bottom wall section 32. For example, in Figure 1, each of the first terminal locking section 35A and the second terminal locking section 35B has such an inclined surface that slopes downward toward the storage chamber 34. This inclined surface makes it easier to store the female terminal 20 in the storage chamber 34 from directly above.
[0023] The lower surfaces (the surfaces facing the storage chamber 34) of the first terminal locking portion 35A and the second terminal locking portion 35B are formed as horizontal surfaces parallel to the bottom wall portion 32. This horizontal surface increases the contact area between the first terminal locking portion 35A and the second terminal locking portion 35B and the upper part of the female terminal 20, making it easier to fix the female terminal 20 in the storage chamber 34.
[0024] The first terminal locking portion 35A and the second terminal locking portion 35B are formed in a part of the storage opening 33 formed at the upper end of the first partition wall portion 31A, for example, in the central part of the storage opening 33 in the direction in which the first partition wall portion 31A extends. By forming the first terminal locking portion 35A and the second terminal locking portion 35B in the central part of the storage opening 33, it is possible to further facilitate the storage of the female terminal 20 into the storage chamber 34 from above the storage opening 33. In addition, multiple first terminal locking portions 35A and second terminal locking portions 35B can be formed at the upper end of the first partition wall portion 31A, and this configuration can further enhance the prevention of the female terminal 20 coming out of the storage chamber 34.
[0025] As shown in Figures 1 to 6, the front end of the storage chamber 34 (in the direction in which the tip 22 of the female terminal 20 is inserted) is provided with a terminal restricting portion 36 that abuts against the tip 22 of the female terminal 20 and restricts the storage position of the tip 22 of the female terminal 20. The terminal restricting portion 36 is L-shaped and locks the upper (storage opening 33 side) tip of the springy electrical contact portion 23 that protrudes from the tip 22 when the female terminal 20 is stored in the storage chamber 34. This configuration prevents and restrains the female terminal 20 after it has been stored in the storage chamber 34 from moving in the extending direction (Y direction) and height direction (Z direction) of the storage chamber 34.
[0026] As shown in Figures 2 to 6, the bottom wall portion 32 of the storage chamber 34 is provided with a terminal fixing portion 37 that protrudes from the bottom wall portion 32 in the direction of the storage opening 33 (Z direction), engages with the recess 24 of the female terminal 20, and fixes the main body portion 21 of the female terminal 20. The terminal fixing portion 37 is located in the center of the width direction (X direction) of the storage chamber 34 and is configured as a projection with a slope toward the protruding tip. This configuration prevents and restrains the female terminal 20 after it has been stored in the storage chamber 34 from moving in the width direction (X direction) and the extension direction (Y direction) of the storage chamber 34.
[0027] As shown in Figure 1, a terminal hole 38 is provided at the front end of the storage chamber 34. This configuration allows the tip of a male terminal (not shown) on a male connector (not shown) to be fitted into the terminal hole 38 and engaged with the electrical contact portion 23 provided on the tip 22 of the female terminal 20. In addition, a wire opening 39 is provided at the rear end of the storage chamber 34 (in the direction of extension of the wire C of the female terminal 20) to allow the wire C of the female terminal 20 to extend to the outside of the terminal storage member 30.
[0028] (Storage procedure for female terminal 20) Next, the procedure for attaching and storing the female terminal 20 in the terminal storage member 30 of this embodiment will be described with reference to Figures 7 to 15. Figure 7 shows the state before the female terminal 20 is stored in the terminal storage member 30. Figure 8 shows the state in the process of storing the female terminal 20, with the tip portion 22 of the female terminal 20 being stored in the terminal storage member 30. Figure 9 shows the state after the female terminal 20 has been stored in the terminal storage member 30. The female terminal 20 is stored in the terminal storage member 30 in the order of Figures 7, 8, and 9, as follows.
[0029] First, as shown in Figure 7, the tip 22 of the female terminal 20 is pointed toward the terminal hole 38 side (-Y direction) of the terminal housing member 30. Then, the female terminal 20 is brought closer to the storage opening 33 of the storage chamber 34 of the terminal housing member 30 from directly above (+Z direction) the storage chamber 34, in a direction parallel to the extension direction (Y direction) of the storage chamber 34, and the storage operation is started.
[0030] Firstly, as shown in Figures 8 and 10, the tip 22 of the female terminal 20, which is close to the storage opening 33, is inserted into the storage chamber 34 at an angle oblique to the direction of extension of the storage chamber 34 from the storage opening 33, and toward the terminal restricting portion 36 and the terminal hole 38.
[0031] Secondly, as shown in Figure 11, the tip 22 of the female terminal 20 inserted into the storage chamber 34 is pushed in until it contacts the terminal restricting portion 36, and then moved to a position between the terminal restricting portion 36 and the terminal fixing portion 37.
[0032] Thirdly, as shown in Figures 12 and 14, after the tip portion 22 is inserted obliquely to the extending direction of the storage chamber 34, the lower surface of the main body portion 21 of the female terminal 20 is pressed against the upper surface (outer surface relative to the storage chamber 34) of the first terminal lock portion 35A and the second terminal lock portion 35B. Furthermore, when the main body portion 21 is pushed toward the storage chamber 34, the first partition portion 31A, which is equipped with the first terminal lock portion 35A and the second terminal lock portion 35B, bends in the width direction (+X direction) of the storage chamber 34, widening the storage opening 33, and allowing the main body portion 21 to be inserted into the storage chamber 34 (see Figure 15).
[0033] Fourth, as shown in Figures 9, 13, and 16, when the main body 21 of the female terminal 20 is pushed in and stored until it contacts the bottom wall 32 of the storage chamber 34, the first terminal locking part 35A and the second terminal locking part 35B return to their original positions. This return of the first terminal locking part 35A and the second terminal locking part 35B locks the female terminal 20 from above. Furthermore, the recess 24 of the female terminal 20 engages with the terminal fixing part 37 in the storage chamber 34, preventing the female terminal 20 from moving in the extending direction of the storage chamber 34. At this time, the elastic electrical contact part 23 of the tip 22, which is held between the terminal restricting part 36 and the terminal fixing part 37, exerts an elastic force in the direction that pushes the terminal restricting part 36 and the terminal fixing part 37 apart. As a result, this elastic force acts as a locking force to hold the female terminal 20 in the storage chamber 34.
[0034] After the female terminals 20 are stored in each of the storage chambers 34 of the terminal storage member 30, the terminal storage member 30 with the female terminals 20 stored inside is inserted into the insertion chamber (not shown) of the male housing and fixed in place by fitting it with the insertion chamber.
[0035] (Effects of this embodiment) As a comparative example of the terminal storage member 30, as shown in Patent Document 1, there is a device in which a sealing piece (terminal locking portion) is formed at the upper end (storage opening) of the partition wall of the terminal storage block, projecting toward the adjacent partition wall, thereby preventing the female terminal from coming out of the storage chamber. In such a comparative example, the sealing piece is not very flexible, which can make it difficult to store the terminal in the storage chamber.
[0036] Furthermore, as shown in this comparative example, simply forming a sealing piece on the upper end of the partition wall of the terminal housing block is not sufficient to secure the female terminal, and there is a possibility that it may come loose from the housing chamber.
[0037] Another comparative example involves a two-step storage process in which the female terminal is partially inserted into the storage chamber from above, and then slid along the length of the storage chamber to set it in the correct position. In this comparative example, it is difficult to easily store the terminal in the storage chamber, making it difficult to automate the wiring of the electric wires.
[0038] In contrast to these comparative examples, the terminal locking portions 35A and 35B according to this embodiment are provided only in the first partition portion 31A of the two partition portions 31B in the storage opening 33, and protrude from the first partition portion 31A toward the second partition portion 31B.
[0039] This configuration ensures that there is space for the terminal locking parts 35A and 35B to flex when the female terminal 20 is inserted. For example, by having the terminal locking parts 35A and 35B located only on one side of the first partition wall 31A and the second partition wall 31B, it is possible to ensure that there is space for the terminal locking parts 35A and 35B to flex when the female terminal 20 is inserted. Therefore, the automation of wiring is facilitated.
[0040] Furthermore, this configuration allows the terminal housing member 30 to suppress vertical play of the female terminal 20, improving seismic resistance and thus ensuring contact reliability. In addition, it prevents the female terminal 20 inside the housing chamber 34 of the inserted terminal housing member 30 from coming out of the housing opening 33.
[0041] Furthermore, the terminal housing member 30 has multiple terminal locking parts (first terminal locking part 35A and second terminal locking part 35B) in the direction in which the first partition wall part 31A extends. This configuration increases the fixing force of the female terminal 20 housed in the housing chamber 34 compared to the case where only one terminal locking part is provided, thereby further strengthening the prevention of the female terminal 20 coming out of the housing chamber 34. Note that the protruding length (X direction), width (Y direction), and thickness (Z direction) of the multiple terminal locking parts 35A, 35B may be uniform, or they may each have different dimensions.
[0042] Furthermore, the terminal storage member 30 may have multiple terminal locking portions (first terminal locking portion 35A and second terminal locking portion 35B) formed in the central part of the storage opening 33 in the direction in which the first partition portion 31A extends. This configuration makes it easier to store the female terminals 20 in the storage chamber 34 than when the multiple terminal locking portions are formed at the ends of the storage opening 33 in the direction in which the first partition portion 31A extends.
[0043] Furthermore, the terminal storage member 30 includes a terminal restricting portion 36 that contacts the tip portion 22 of the female terminal 20 and restricts the storage position of the tip portion 22 of the female terminal 20, and a terminal fixing portion 37 that protrudes from the bottom wall portion 32 toward the storage opening 33 and fixes the main body portion 21 of the female terminal 20. With this configuration, after the female terminal 20 is stored in the storage chamber 34, the movement of the storage chamber 34 in the extension direction and height direction is restricted by the terminal restricting portion 36, and the movement of the storage chamber 34 in the width direction and extension direction is restricted by the terminal fixing portion 37. Therefore, it is possible to further firmly prevent the female terminal 20 from coming out of the storage chamber 34.
[0044] Furthermore, the terminal storage member 30 has storage chambers 34 made of a flexible material and has multiple storage chambers 34, each for storing multiple female terminals 20. This configuration allows various types of wire harnesses to be used together in a single terminal storage unit 10 equipped with the terminal storage member 30. In addition, the terminal storage member 30 has storage chambers 34 made of a flexible material, and terminal locking parts 35A and 35B are located on the first partition wall 31A on one side of the storage chamber 34. With this configuration, even if there are multiple adjacent storage chambers 34, space is secured for the terminal locking parts 35A and 35B to bend easily when inserting the female terminals 20, so that female terminals 20 can be stored in each storage chamber 34 simultaneously. Therefore, the work can be expedited.
[0045] Furthermore, the terminal storage member 30 can be configured by arranging and connecting multiple storage chambers 34, each for housing multiple female terminals 20, in parallel, and cutting the storage chambers 34 into the desired number of units to create a KitKat-type terminal storage plate. This configuration allows the terminal storage member 30 to be utilized according to the required number of female terminals 20 and their intended use.
[0046] Furthermore, the terminal locking portions 35A and 35B are located on the outside of the storage chamber 34 and have inclined surfaces that slope from the first partition wall portion 31A toward the second partition wall portion 31B toward the bottom wall portion 32. With this configuration, the female terminal 20 can be easily pushed into the storage chamber 34 from above the storage opening 33, so that the female terminal 20 can be stored in the terminal storage member 30 in a single step.
[0047] In the above embodiment, the connector comprising the terminal storage unit 10 may include a male housing as the housing. However, the connector may include any type of housing. As a modification, the connector may include a female connector as the housing instead of a male housing.
[0048] In the above embodiment, a female terminal 20 is attached to the terminal housing member 30. However, any type of terminal may be attached to the terminal housing member 30. As an example, a male terminal may be attached to the terminal housing member 30 instead of the female terminal 20.
[0049] In the above embodiment, the terminal housing member 30 comprises a first partition wall portion 31A as a first partition wall portion and a second partition wall portion 31B as a second partition wall portion. However, either one may be the first partition wall portion and the other may be the second partition wall portion. As a modified example, the terminal housing member 30 may comprise a first partition wall portion 31A as a second partition wall portion and a second partition wall portion 31B as a first partition wall portion.
[0050] Several embodiments and modifications have been described above. However, the embodiments and modifications are not limited to the examples described above. For example, the embodiments and modifications may be implemented in combination with each other. [Explanation of symbols]
