[0009] Embodiment 1 An electrical connector 1 according to an embodiment of the present invention will be described below with reference to the drawings. For ease of understanding, mutually orthogonal XYZ coordinates are set and referenced as appropriate. As shown in FIG. 1, the -X direction of the XYZ coordinates is the same as the insertion direction D1 in which the female connector 20 is inserted into the male connector 10. The Z axis direction is the same as the height direction D2 of the electrical connector 1, and the Y axis direction is the same as the width direction D3 of the electrical connector 1.

[0010] The electrical connector 1 is an electronic circuit component that is installed in, for example, an automobile part. The electrical connector 1 includes a male connector 10 and a female connector 20, as shown in FIGS.

[0011] 3 and 4, male connector 10 is attached to circuit board 90 as an object to be mounted, and is mated with female connector 20. Male connector 10 includes housing 10a, hold-down portion H, and male terminals 30.

[0012] As shown in FIGS. 1 and 2, the housing 10a is a substantially rectangular box-shaped member having a pair of side walls 13R and 13L, a ceiling wall 14, a bottom wall 15, and a rear end wall 16.

[0013] The side walls 13R, 13L are formed as wall portions on both sides of the width direction D3 of the approximately rectangular box shape of the housing 10a. A first recess 11 is formed inside each of the side walls 13R, 13L. The first recess 11 is formed as a groove extending along the insertion direction D1 (X-axis direction). In the present embodiment, the first recess 11 is formed in each of the side walls 13R, 13L, but this is not limited thereto. For example, the first recess 11 may be formed in one of the side walls 13R, 13L. The first recess 11 may also be formed in a wall portion other than the side walls 13R, 13L. For example, the first recess 11 may be formed in one or both of the ceiling wall 14 and the bottom wall 15. The first recess 11 is formed inside each of the side walls 13R, 13L, but this is not limited thereto. The first recess 11 may be formed on the outside of the side wall portions 13R and 13L. Furthermore, the first recess 11 may be formed on the outside of a wall portion other than the side wall portions 13R and 13L.

[0014] The ceiling wall portion 14 is formed as a wall portion closer to the +Z side of the substantially rectangular box shape of the housing 10a.

[0015] The bottom wall 15 is formed as a wall portion closer to the -Z side of the substantially rectangular box shape of the housing 10a. The bottom wall portion 15 is a wall portion that comes into contact with the circuit board 90.

[0016] The rear end wall portion 16 is formed as a wall portion closer to the -X side of the substantially rectangular box shape of the housing 10a.

[0017] The housing 10a formed as described above has an accommodating space S and an opening S1 communicating from the accommodating space S to the outside formed inside the substantially rectangular box shape.

[0018] The opening S1 is formed in the housing 10a so as to open in the +X direction. A part of the female connector 20 is fitted into the opening S1 and is accommodated in the accommodation space S inside the housing 10a.

[0019] In the first embodiment, the housing 10a is made of a material obtained by solidifying molten resin. Specifically, the housing 10a is formed by pouring molten resin into injection molds 80A and 80B having two gates 81 and 82, for example, as shown in FIGS. 5 and 6, and then solidifying the molten resin. In the first embodiment, the housing 10a is formed by pouring resin through the two gates 81 and 82 into a portion 16a where the rear end wall portion 16 of the housing 10a (see FIGS. 1 and 2) will be formed. As a result, a gate mark 17, which is an inlet for the molten resin, is provided in the rear end surface (the surface closer to the -X direction) of the rear end wall portion 16 of the housing 10a, as shown in FIG.

[0020] The gate marks 17 are provided in the center in the width direction D3, and at least one pair of gate marks 17 are provided along the height direction D2. In the present embodiment 1, the pair of gate marks 17 are formed to have different areas.

[0021] Furthermore, since the housing 10a is formed using injection molding dies 80A, 80B (see FIGS. 5 and 6) having two gates 81, 82, weld lines L are formed in the side wall portions 13R, 13L, etc. of the housing 10a, as shown in FIGS. 1 and 2. The weld lines L are molding defects (areas where the molten resin joins) that occur during molding of the molten resin, and in the present embodiment 1, they are formed in the shape of slightly wavy waves that extend along the insertion direction D1.

[0022] As shown in FIG. 7, the first recess 11 is formed on the sidewalls 13R and 13L so as to be positioned closer to the +Z side (to one side) in the height direction D2 of the male connector 10 than the position of the weld line L. Therefore, the first recess 11 is not formed at the same position in the height direction D2 of the male connector 10 as the weld line L, but is formed at a position shifted in the height direction D2, specifically, higher than the weld line L. Also, as shown in FIG. 2, an inclined surface 11a inclined at a predetermined angle with respect to the insertion direction D1 is formed on the lower edge of the opening of the first recess 11. The inclined surface 11a is formed to facilitate the fitting of the first protrusion 21 into the first recess 11 when the female connector 20 is fitted to the male connector 10, as well as to guide the insertion of the first protrusion 21 of the female connector 20.

[0023] 1 and 2, the hold-down portion H is a member that is disposed on the outer surfaces of the sidewall portions 13R, 13L of the housing 10a and is fixed to the surface of the circuit board 90 that is the mounting target. The hold-down portion H is formed, for example, by bending a plate-shaped metal member into an L-shape. The hold-down portion H is used to firmly fix the housing 10a and the circuit board 90 together.

[0024] As shown in Fig. 4, the male terminal 30 is disposed so as to penetrate the rear end wall portion 16 of the housing 10a. The male terminal 30 is formed by pressing a conductive plate material such as copper or a copper alloy. One end of the male terminal 30 protrudes into the accommodation space S of the housing 10a. The other end of the male terminal 30, i.e., the end closer to the -X side, protrudes from the rear end wall portion 16 of the housing 10a closer to the -X side, as shown in Fig. 4. The end closer to the -X side of the male terminal 30 is electrically connected to a conductor portion provided on the surface of the circuit board 90 by, for example, soldering.

[0025] As shown in FIGS. 1 and 2, the female connector 20 includes a housing 20a, a first protrusion 21, a lock arm 23, a locking portion 24, an operating portion 25, and a female terminal 40.

[0026] The housing 20a is formed so that it can be accommodated in the accommodation space S of the housing 10a of the male connector 10. Specifically, the housing 20a is formed in a shape that corresponds to the internal shape of the accommodation space S of the male connector 10, and is also formed in a shape that can be fitted into the opening S1. A terminal accommodation chamber for accommodating the female terminal 40 is formed in the housing 20a.

[0027] The first protrusions 21 are provided on the side surface of the housing 20a closer to the -Y side and the side surface of the housing 20a closer to the +Y side, respectively. The first protrusions 21 are formed in an elongated convex shape that extends along the insertion direction D1, and fit into the first recesses 11.

[0028] Two lock arms 23 are provided on the top surface of the housing 20a. The lock arms 23 are formed to be flexible in the height direction D2.

[0029] A locking portion 24 is provided on each of the two locking arms 23. The locking portion 24 is formed to protrude in the +Z direction from each of the locking arms 23. The locking portion 24 is formed so as to be able to be locked to a locked portion (not shown) formed inside the male connector 10.

[0030] The operating portion 25 is used for releasing the engagement between the locking portion 24 and the locked portion of the male connector 10 when pressed by a user of the electrical connector 1 .

[0031] As shown in Fig. 2, the female terminal 40 is accommodated in a terminal accommodating chamber of the housing 20a. The female terminal 40 has, for example, a cylindrical portion capable of receiving the male terminal 30 (see Fig. 4) to be connected, and a crimped portion to which the cable 50 is crimped and connected. When the female terminal 40 is attached to the housing 20a, the cable 50 connected to the female terminal 40 is pulled out from the housing 20a.

[0032] In the electrical connector 1 configured as described above, as shown in FIGS. 8 and 9, when the dimension of the groove of the first recess 11 is A, the dimension of the width of the first protrusion 21 is B, and the inclination angle of the inclined surface 11a with respect to the insertion direction D1 is Y, A>α×B (1) (where 1≦α≦1.0641) 25°≦Y≦45° (2) The insulating film is formed so as to satisfy the following relational expression.

[0033] Specifically, in the first embodiment, the electrical connector 1 includes: A / B=1.0641(α=1.0641) ···(3) The insulating film is formed so as to satisfy the following relational expression.

[0034] In addition, when the female connector 20 is inserted into the male connector 10, the inclination angle of the female connector 20 relative to the insertion direction D1 is defined as X. A>B / cosX (4) X≦20° (5) (X+Y)<45° (6) In other words, the female connector 20 is formed to satisfy the relational expression (5). Relational expression (5) indicates that the female connector 20 is inserted into the male connector 10 within a range where the inclination angle X is 20° or less. Furthermore, "α" in the above relational expression (1) represents "secX", which is the reciprocal of "cosX", or in other words, "1 / cosX". Furthermore, the upper limit of "α", "1.0641", is a value calculated from "1 / cos20°" in the above relational expression (5) because the inclination angle X of the female connector 20 is 20° or less (1 / cos20° ≒ 1 / 0.9397 ≒ 1.0641).

[0035] As described above, in the electrical connector 1 according to the first embodiment, the dimension A of the groove of the first recess 11, the dimension B of the width of the first protrusion 21, and the inclination angle Y of the inclined surface 11a with respect to the insertion direction D1 are formed to satisfy the above-mentioned relational expression. Therefore, as shown in FIGS. 1 and 2 , when the female connector 20 is inserted into the male connector 10, the first protrusion 21 of the female connector 20 abuts against the inclined surface 11a of the first recess 11 of the male connector 10, thereby guiding the female connector 20 toward the housing space S of the male connector 10, and the inclination angle X of the female connector 20 with respect to the insertion direction D1 is kept to 20° or less. As a result, as shown in FIG. 9 , the first protrusion 21 is likely to come into contact with the inclined surface 11a of the first recess 11 before coming into contact with the upper edge 11b of the first recess 11.

[0036] For example, in the electrical connector 1A according to the comparative example, as shown in FIG. 10, the female connector 20 is inserted into the male connector 10 with its inclination angle X greater than 20° (X>20°). As a result, the first protrusion 21 may contact the upper edge 11b of the first recess 11 before contacting the inclined surface 11a of the first recess 11. In this case, this contact may result in, for example, a force F being applied to the first recess 11, which tends to open the first recess 11 in the height direction D2. This may cause deformation in the direction in which the opening of the male connector 10 widens, potentially resulting in damage to the male connector 10, such as cracking. Furthermore, the force F may cause a crack in the weld line L.

[0037] However, in the electrical connector 1 according to the first embodiment, as shown in Figures 8 and 9, the inclination angle X of the female connector 20 relative to the insertion direction D1 when the female connector 20 is inserted into the male connector 10 is kept to 20° or less. Therefore, the first protrusion 21 is likely to come into contact with the inclined surface 11a of the first recess 11 before coming into contact with the upper edge 11b of the first recess 11. This makes it difficult for a force F (see Figure 10) that would open the first recess 11 in the height direction D2 to be applied to the first recess 11, for example, thereby preventing damage to the male connector 10. As a result, in the first embodiment, damage that may occur when the male connector 10 is inserted into the female connector 20 can be prevented.

[0038] Furthermore, in the first embodiment, first recess 11 is formed in the wall of housing 10a so as to be positioned closer to +Z in height direction D2 than the position where weld line L is provided. That is, first recess 11 and weld line L are not formed in the same position in height direction D2. Therefore, damage to first recess 11 and weld line L can be suppressed compared to when first recess 11 and weld line L are formed in the same position in height direction D2. As a result, in the first embodiment, damage that may occur when male connector 10 is inserted into female connector 20 can be suppressed.

[0039] 3, in the present embodiment 1, the gate marks 17 are provided in the center in the width direction D3 and in pairs along the height direction D2, which makes it easier to change or adjust the height position of the weld line L in the height direction D2.

[0040] Embodiment 2 In the electrical connector 1 according to the first embodiment, as shown in Figures 1 and 2, one first recess 11 is formed in each of the side walls 13R, 13L of the housing 10a. However, this is not limited to this. As in the electrical connector 2 according to the second embodiment shown in Figures 11 and 12, in addition to the first recess 11, a second recess 12 may be formed in the side walls 13R, 13L of the housing 10a of the male connector 10. In this case, the female connector 20 includes, in addition to the first protrusion 21, a second protrusion 22 that extends along the insertion direction D1 at a distance from the first protrusion 21.

[0041] The second recess 12 is formed in one of the side walls 13R and 13L, that is, the side wall 13L. As shown in FIGS. 13 and 14 , the second recess 12 extends along the insertion direction D1 at a distance from the first recess 11. In the second embodiment, the second recess 12 is not formed in the other of the side walls 13R and 13L, that is, the side wall 13R. In the second embodiment, a weld line L is provided between the second recess 12 and the first recess 11. As shown in FIGS. 12 and 13 , an inclined surface 12a is formed on the upper edge of the opening of the second recess 12, inclined at a predetermined angle with respect to the insertion direction D1. The inclined surface 12a is formed to facilitate the fitting of the second protrusion 22 into the second recess 12 when the female connector 20 is fitted to the male connector 10, and also to guide the insertion of the second protrusion 22 of the female connector 20. In the second embodiment, the inclination angle Y' of the inclined surface 12a is the same as the inclination angle Y of the first convex portion 21 (Y=Y'). However, this is not limited to this. The inclination angle Y' of the inclined surface 12a does not have to be the same as the inclination angle Y of the first convex portion 21 (Y≠Y'). However, it is desirable that the inclination angle Y' of the inclined surface 12a be an angle that is close to the inclination angle Y of the first convex portion 21.

[0042] As shown in Figures 11 and 12, the second protrusion 22 is provided on one of the side surfaces closer to the -Y side and the side surfaces closer to the +Y side of the housing 20a. This second protrusion 22 is fitted into the second recess 12 and is formed in a convex shape that extends elongatedly along the insertion direction D1. As shown in Figures 13 and 14, the second protrusion 22 is provided along the insertion direction D1 at a distance from the first protrusion 21. Note that in the second embodiment, the second protrusion 22 is not provided on the other of the side surfaces closer to the -Y side and the +Y side of the housing 20a.

[0043] In the electrical connector 2 configured as described above, when the groove dimension of the first recess 11 is A, the width dimension of the first protrusion 21 is B, the groove width of the second recess 12 is C, the width dimension of the second protrusion 22 is D, and the inclination angle of the inclined surface 11a with respect to the insertion direction D1 is Y, A>α×B (1) C>α×D (7) (where 1≦α≦1.0641) 25°≦Y=Y'≦45° (8) The insulating film is formed so as to satisfy the following relational expression.

[0044] Specifically, in the first embodiment, the electrical connector 2 includes: A / B=C / D=1.0641(α=1.0641) ···(9) 25°≦Y=Y'≦45° (10) The insulating film is formed so as to satisfy the following relational expression.

[0045] As described above, in the second embodiment, the electrical connector 2 is formed such that the groove dimension A of the first recess 11, the width dimension B of the first protrusion 21, the groove dimension C of the second recess 12, the width dimension D of the second protrusion 22, and the inclination angles Y and Y' of the inclined surfaces 11a and 12a relative to the insertion direction D1 satisfy the above-mentioned relational expressions. This prevents the insertion angle of the female connector 20 relative to the male connector 10 from becoming too large. As a result, in the second embodiment, damage that may occur when the male connector 10 is inserted into the female connector 20 can be prevented.

[0046] In the second embodiment, the weld line L is located between the first recess 11 and the second recess 12. That is, the second recess 12 and the weld line L are not formed at the same position in the height direction D2. Therefore, compared to when the second recess 12 and the weld line L are formed at the same position in the height direction D2, damage such as cracks to the second recess 12 and the weld line L can be suppressed. As a result, in the second embodiment, damage that may occur when the male connector 10 is inserted into the female connector 20 can be suppressed.

[0047] Also, in the second embodiment, the same effects as those in the first embodiment can be achieved.

[0048] Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments.

[0049] For example, in the first embodiment, as shown in Fig. 7, the first recess 11 is formed in the sidewalls 13R, 13L so as to be positioned closer to +Z (to one side) in the height direction D2 of the male connector 10 than the position where the weld line L is provided. However, this is not limited thereto. The first recess 11 may also be formed so as to be positioned closer to -Z (to the other side) in the height direction D2 than the position where the weld line L is provided.

[0050] 13 and 14, the weld line L is provided between the first recess 11 and the second recess 12. However, this is not limiting. The weld line L does not have to be provided between the first recess 11 and the second recess 12.

[0051] In the first embodiment, as shown in Fig. 3, the gate marks 17 are provided in the center of the width direction D3 and at least one pair are provided along the height direction D2. However, this is not limited to this. Three or more gate marks 17 may be provided. In this case, it is preferable that the three or more gate marks 17 are provided in the center of the width direction D3 and along the height direction D2.

[0052] In the first embodiment, as shown in Fig. 3, the pair of gate marks 17 are formed to have different areas. However, this is not limitative. The pair of gate marks 17 may be formed to have the same area.

[0053] In the second embodiment, as shown in Fig. 11, the second recess 12 is formed in one of the side walls 13R, 13L, that is, the side wall 13L. However, this is not limited to this. As in the electrical connector 3 according to the third embodiment shown in Fig. 15, the second recess 12 may be formed in both of the side walls 13R, 13L. In this case, the second protrusion 22 is provided on both the side surface closer to the -Y direction and the side surface closer to the +Y direction of the housing 20a of the female connector 20.

[0054] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and do not limit the scope of the present invention. [Explanation of symbols]
