In order to guide the bottom surface 27 of the fitting protrusion 22 , it is preferable to provide a tapered portion 54 a on the front side of the reference surface 54 . The reference plane 54 is positioned below the vertical direction "β" in a state separated from the elastic contact portion 62a in the vertical direction "β". Since the reference surface 54 and the bottom surface 27 of the fitting convex portion 22 are all formed as flat surfaces, the fitting convex portion 22 is slid on the flat surface and is finally placed on the reference surface 54 to be held in the insertion position. Space 52.

In the insertion space 52, a flat surface 56 is provided along the fitting direction "α". The bottom surface 23a (see FIG. 4 ) of the protrusion 23 slides and is finally placed. In order to guide the bottom surface 23 a of the lance-shaped protrusion 23 , it is preferable to provide a tapered portion 56 a on the front side of the surface 56 . Since the surface 56 and the bottom surface 23a of the lance-shaped protrusion 23 are both formed as flat surfaces, the lance-shaped protrusion 23 is held in the insertion space 52 while slidingly contacting each other on the flat surface and finally placed on the surface 56 . Furthermore, corresponding to the step difference between the bottom surface 27 of the fitting protrusion 22 and the bottom surface 23a of the lance-shaped protrusion 23, the reference plane 54 is positioned slightly higher than the plane 56 in the vertical direction "β".

The protruding portions 55 protrude toward the side opposite to the protruding portion 25 , in other words, toward the side close to the reference plane 54 in the up-down direction “β”.

Next, the functions of the protrusions 25, 55 will be described with reference to FIGS. 6 to 9 . Fig. 6 and Fig. 7 are the I-I line sectional view and the II-II line sectional view of Fig. 2 respectively, showing the state after the cable connector 20 and the board connector 50 are fitted, in other words, showing that the cable terminal 40 has been The state after being inserted into the insertion space 65 of the board terminal 60 . In addition, Fig. 8 and Fig. 9 are diagrams corresponding to the cross-sectional view of line I-I in Fig. 2 and diagrams corresponding to the cross-sectional view of line II-II, which are different from Fig. 6 and Fig. The state before the device 50 is completely fitted, in more detail, shows the insertion of the fitting protrusion 22 of the cable housing 21 into the substrate housing 51. The cable terminal 40 is inserted into the space 52 , especially the state immediately after the tapered portion 42 provided at the front end of the cable terminal 40 comes into contact with the elastic contact portion 62 a of the board terminal 60 .

As shown in FIG. 8, when the tapered portion 42 of the cable terminal 40 is in contact with the elastic contact portion 62a of the substrate terminal 60, the cable terminal 40 passes through the contact with the elastic contact portion 62a and moves upward in the vertical direction “β”. The side close to the reference plane 54 is pressed. Moreover, when the cable terminal 40 is pressed toward the side close to the reference plane 54 in the vertical direction "β" through the contact with the elastic contact part 62a, as shown in FIG. It abuts against the protruding portion 55 of the substrate housing 51. Through this abutment, the cable housing 21, and more specifically, the cable terminal 40 supported by the cable housing 21 also faces in the vertical direction "β". The side close to the reference plane 54 is pressed. In this way, according to this structure, since the direction in which the cable terminal 40 is pressed through contact with the elastic contact portion 62a, and the cable housing 21 furthermore, the cable terminal 40 supported by the cable housing 21 penetrates The abutment of the protruding portion 25 and the protruding portion 55 are pressed in the same direction, so when the cable terminal 40 is in contact with the elastic contact portion 62a, the force applied to the board terminal 60 can be reduced, and the force associated with the cable connector and contact with the cable connector can be reduced. Damage, deterioration, etc. of the board terminal 60 caused by the plugging and unplugging of the board connector.

In particular, in this embodiment, the timing at which the cable terminal 40 comes into contact with the elastic contact portion 62a and the timing at which the protruding portion 25 of the cable housing 21 abuts with the protruding portion 55 of the substrate housing 51 are made almost simultaneously. Thus, the load applied to the board terminal 60 can be more effectively reduced. However, these points in time do not necessarily need to be made at the same time.

When the cable connector 20 is fitted into the board connector 50, as shown in FIG. To the recess 41 of the upper contact surface 47 of the cable terminal 40 exposed from the cable housing 21 . As a result, the board terminal 60 and the cable terminal 40 can be connected more reliably. Moreover, the concave portion 41 provided on the cable terminal 40 is located at the contact portion of the elastic contact portion 62a, and is set in a state of being recessed toward the side close to the reference plane 54 in the vertical direction “β”, so it also has the function of reducing the force applied to the substrate. The role of the load of terminal 60. Moreover, the concave portion 41 is not provided on the lower contact surface 46 of the cable terminal 40, but is provided on the upper contact surface 47, so the contact between the cable terminal 40 and the substrate terminal 60 is not hindered, and furthermore, it is not hindered. The lower contact surface 46 of the cable terminal 40 is in contact with the surface 61b of the support portion 61 of the substrate terminal 60, so even if a recess is provided, the cable terminal 40 can be smoothly inserted into the insertion space 65 of the substrate terminal 60 . When the cable connector 20 and the substrate connector 50 are fitted, the fitting state of the cable connector 20 and the substrate connector 50, and more specifically, the connection state of the substrate terminal 60 and the cable terminal 40 is shown in FIG. 7 . As shown, the protrusions 25 and 55 are locked. Therefore, in order to release the mated state of the cable connector 20 and the board connector 50, it is necessary to make the protrusions 25 and 55 interfere and allow the protrusions 25 to pass over the protrusions 55. . In this way, the protrusions 25 and 55 not only function to reduce the load applied to the board terminal 60 but also function as a locking mechanism.

In addition, this invention is not limited to the said embodiment, Various changes are possible. For example, in the embodiment described above, the protruding portion 55 of the substrate case 51 is provided on the left and right inner surfaces of the terminal arrangement direction "γ" of the insertion space 52, in other words, in the direction along the terminal arrangement direction "γ". They are arranged outside the array of substrate terminals 60, but they may also be arranged in the middle of the array of substrate terminals 60, and may also be arranged on the left and right inner surfaces and in the middle, and may not be arranged on the left and right inner surfaces but only in the middle. .

Also, it is not necessary to provide the protruding portion 25 of the cable housing 21. Even if the protruding portion is not provided, if the abutment between the cable housing 21 and the protruding portion 55 of the substrate housing 51 can be used to guide the cable terminal 40 toward the reference The side of surface 54 can be pressed. Therefore, in the cable housing 21 , there should only be a portion that comes into contact with the protruding portion 55 of the board housing 51 .

In addition, in the embodiment described above, the reference plane 54 is provided on the substrate case 51, but it may also be provided on the substrate terminal 60, and furthermore, it may be provided on the flat surface of the support portion 61 of the substrate terminal 60. The surface 61b (refer to FIG. 5 ) is formed, and it can also be formed by the flat surface 61b and the reference surface 54 .
