Thereby, the female connector 10 and the male connector 30 can be fitted in the correct direction. A connecting lever 19 is attached to the lever attaching portion 11b. The configuration of the connecting lever 19 will be described later.

  Next, the male connector 30 will be described. 4 to 6 are a perspective view, a side view, and an exploded perspective view of the male connector 30. FIG. In the following description, in the description of the male connector 30, the side fitted to the female connector 10 (the lower left side in FIGS. 4 and 6) is referred to as the assembly side, and the opposite side (the upper right side in FIGS. 4 and 6). ) Is referred to as the proximal side.

  As shown in FIG. 6 and the like, the male connector 30 includes an outer housing 31, a shield cover 32, a male retainer 33, an inner housing 35, an electric wire waterproof seal 37, an electric wire cover 38, and a male terminal 40. .

  The male terminal 40 is electrically connected to the electric wire 4 and is electrically connected to the female terminal 20. As shown in FIG. 6, the male terminal 40 includes a crimping portion 41 and a terminal portion 43.

  The crimp portion 41 is crimped to the conductor portion of the electric wire 4. The terminal portion 43 is a metal flat plate that is electrically connected to the crimping portion 41.

  The inner housing 35 is formed with an insertion hole 35 a for inserting the male terminal 40 and a holding portion 35 b for holding the male terminal 40. An operator who assembles the male connector 30 inserts the male terminal 40 into the insertion hole 35a, and fits the mounting hole of the male terminal 40 with the protrusion formed on the holding portion 35b. 40 can be attached to the inner housing 35.

  The electric wire waterproof seal 37 is a ring-shaped member made of silicon, rubber (including silicon rubber), or the like. The electric wire waterproof seal 37 is attached to the proximal end side of the insertion hole 35a by the electric wire cover 38 after the male terminal 40 is attached to the inner housing 35. Thereby, it can prevent that the water which propagates the electric wire 4 permeates in the male connector 30. FIG.

  The male retainer 33 is attached so as to cover the holding portion 35 b of the inner housing 35. Therefore, the male retainer 33 is disposed so as to cover the male terminal 40.

  The shield cover 32 is a metal cylindrical member. The shield cover 32 is disposed so as to cover the assembly side of the inner housing 35. Thereby, it can prevent that the noise radiated | emitted from the electric wire 4 and the male terminal 40 leaks outside (it can shield).

  The outer housing 31 is attached to the inner housing 35 so as to cover the shield cover 32. The outer housing 31 is formed with a female connector guide portion 31a and a lever mounting portion 31b. As described above, the female connector guide portion 31a is configured such that the male connector guide portion 11a can be inserted. The lever mounting portion 31b is configured so that the connecting lever 19 can be attached and detached.

  As shown in FIG. 3 and the like, the connecting lever 19 is formed with a mounting portion 19a and a guide portion 19b in which a guide groove is formed. The connecting lever 19 is rotatably attached to the outer housing 11 by inserting the lever attaching portion 11b into the attaching portion 19a. The connecting lever 19 is attached to the outer housing 31 by inserting the lever attaching portion 31b into the guide portion 19b. With this configuration, by rotating the connecting lever 19 around the mounting portion 19a, the lever mounting portion 31b moves along the guide portion 19b, so that the outer housing 31 (and thus the male connector 30) is brought closer to the female connector 10. Or it can be moved in the direction of separation. Therefore, it is possible to reduce the operating force required for the operator. Therefore, since the male connector 30 and the female connector 10 can be strongly fitted, the waterproof waterproof seal 14 can be strongly compressed to exert a waterproof effect.

  Next, the positional relationship of each component (particularly, the female terminal 20, the male terminal 40, the female retainer 13, and the male retainer 33) when the male connector 30 is inserted into and fitted into the female connector 10 will be described in detail. FIG. 7 is a perspective view showing the shape and positional relationship of the female retainer 13 and the male retainer 33. FIG. 8 is a perspective view showing a state when the male retainer 33 is inserted into the female retainer 13. 9 is a cross-sectional view taken along the line AA in FIG.

  First, the shapes of the female retainer 13 and the male retainer 33 will be described. As shown in FIG. 7, the female retainer 13 is formed with insertion portions 13 a to 13 c. On the other hand, the male retainer 33 is formed with protruding plates 33a and 33c.

  The female retainer 13 includes two rectangular parallelepiped members (members individually covering the two female terminals 20) in which the insertion portions 13a and 13b are formed. Each of the rectangular parallelepiped members has three insertion portions. Each of the three insertion portions has an elongated rectangular opening, and the openings are arranged in parallel to each other. Of these three insertion portions, the insertion portions located at both ends (the upper end and the lower end in FIG. 7) are denoted by reference numeral 13a, and the insertion portion formed between the insertion portions 13a is denoted by reference numeral 13b. Further, a gap (insertion portion) is formed between the rectangular parallelepiped members, and this insertion portion is denoted by reference numeral 13c. The insertion portion 13c is formed in a slit shape, and is arranged so that the direction is perpendicular to the insertion portions 13a and 13b. Since it is configured as described above, when viewed generally, the female retainer 13 is formed with four insertion portions 13a, two insertion portions 13b, and one insertion portion 13c.

On the other hand, the male retainer 33 is formed with a protruding plate 33 a (a member that individually covers the two male terminals 40) disposed so as to face each other with the terminal portion 43 interposed therebetween. In this embodiment, since it is the structure which uses the two male terminals 40, the male retainer 33 will be provided with a total of four protrusion plates 33a. The male retainer 33 also includes a protruding plate (vertical protruding plate) 33c disposed between the two male terminals 40 in a direction perpendicular to the protruding plate 33a. The male retainer 33 is arranged so as to cover the male terminal 40 and prevent the male terminal 40 from protruding between the male retainers 33 in order to prevent dust and the like from adhering to the male terminal 40.

  When the male connector 30 is inserted into the female connector 10 (that is, the male retainer 33 is inserted into the female retainer 13), the male retainer 33 enters between the sandwiching portion 23 and the female retainer 13 as shown in FIG. This will be specifically described below. That is, the four protruding plates 33 a of the male retainer 33 are inserted into the four insertion portions 13 a of the female retainer 13. The terminal portions 43 of the two male terminals 40 are inserted into the two insertion portions 13 b of the female retainer 13. The protruding plate 33 c of the male retainer 33 is inserted into one insertion portion 13 c of the female retainer 13.

  The protruding plates 33a and 33c are configured to be in contact with the inner wall surfaces of the insertion portions 13a and 13c, respectively. Thereby, for example, when a force is applied to the connector, the projecting plates 33a and 33c and the inner wall surfaces of the insertion portions 13a and 13c come into contact with each other to exert a force, whereby the force can be dispersed.

  More specifically, the insertion part 13a is arrange | positioned so that the insertion part 13b in which the terminal part 43 of the male terminal 40 is inserted may be inserted | pinched (so that the connection location of the female terminal 20 and the male terminal 40 may be inserted | pinched). Therefore, it is possible to give resistance to the force in the vertical direction in FIG.

  Moreover, the insertion part 13c is arrange | positioned between the two insertion parts 13b in which the terminal part 43 of the male terminal 40 is inserted. Therefore, it is possible to give resistance to the force in the direction in which the female terminal 20 and the male terminal 40 are arranged (the front and back direction in FIG. 9) at the connection location.

  As described above, the connector of the present embodiment includes the male connector 30 and the female connector 10. The male connector 30 holds the male terminal 40. The female connector 10 can hold the female terminal 20 and can be fitted to the male connector 30. The male connector 30 includes a male retainer 33 disposed so as to individually cover the male terminals 40. The female connector 10 includes a female retainer 13 disposed so as to individually cover the female terminals 20. In a state where the male connector 30 and the female connector 10 are fitted, the male retainer 33 is positioned between the female terminal 20 and the female retainer 13.

  Thereby, since the male retainer 33 and the female retainer 13 can be overlapped and the male connector 30 and the female connector 10 can be fitted, the size of the connector when both connectors are connected can be made compact. . Further, the movement of the female terminal 20 can be restricted by the male retainer 33. Therefore, the reliability of connection between the male terminal 40 and the female terminal 20 can be increased.

  Moreover, in the connector of this embodiment, in the state which fitted the male connector 30 and the female connector 10, the surface of the male retainer 33 and the surface of the female retainer 13 can contact.

  Thereby, even if it is a case where force is applied to a connector, the force can be disperse | distributed because retainers contact each other and exert force. Therefore, the reliability of connection between the male terminal 40 and the female terminal 20 can be further increased.

  In the connector of this embodiment, the female retainer 13 is formed with insertion portions 13a and 13c. In a state where the male connector 30 and the female connector 10 are fitted, the protruding plates 33a and 33c of the male retainer 33 are inserted into the insertion portions 13a and 13c.

  Thereby, since the male retainer 33 inserted in the insertion portions 13a and 13c is restricted from moving in a plurality of directions, a connector resistant to forces in various directions can be realized. Therefore, the reliability of connection between the male terminal 40 and the female terminal 20 can be further increased.

  Moreover, in the connector of this embodiment, the insertion part 13a is a hole formed in the position which pinches | interposes the insertion part 13b.

  Thereby, when force is applied to the connector, the male terminal 40 and the female terminal 20 can be well protected. Therefore, the reliability of connection between the male terminal 40 and the female terminal 20 can be further increased.

  Moreover, in the connector of this embodiment, the insertion part 13c is a hole formed between the two insertion parts 13b.

  Thereby, a connector strong against bending in the direction in which the terminals are arranged can be realized.

  In the connector of the present embodiment, the male retainer 33 is disposed so as to cover the male terminal 40 and so that the male terminal 40 does not protrude from the male retainer 33.

  Thereby, since the male terminal 40 is not exposed, it is possible to prevent dust and the like from adhering to the male terminal 40.

  The preferred embodiment of the present invention has been described above, but the above configuration can be modified as follows, for example.

  In the above embodiment, the configuration in which the male retainer 33 is positioned between the female terminal 20 and the female retainer 13 has been described. However, the female retainer 13 may be positioned between the male terminal 40 and the male retainer 33. That is, the insertion portion may be formed on the female retainer 13 or may be formed on the male retainer 33. Therefore, a hole formed at a position sandwiching a hole into which the female terminal is inserted, or a hole formed between holes into which the female terminal is inserted can be used as the insertion portion.

  Further, the arrangement and shape of the insertion portion are not limited to the example described in the above embodiment, and can be configured appropriately.

  In the said embodiment, although the number of the female terminals 20 and the male terminals 40 is two, the number of terminals is not restricted to this, It can change suitably according to a circuit structure.

  Although the example which applies the connector of this invention to the structure which connects electric wires above was demonstrated, the connector of this invention is applicable also to the structure which connects an electric wire and an auxiliary machine.
