Exists. That is, the protruding piece 14 is present at a position in contact with the first male terminal 20a inserted into the main body 30 from the first insertion port 33a.

  The projecting piece 14 has a leaf spring structure that elastically deforms. For example, the projecting piece 14 is elastically deformed by the application of an external force, and when the external force is released, the projecting piece 14 is restored to the original state by an elastic restoring force. In the present embodiment, when the first male terminal 20a abuts on the projecting piece 14, the projecting piece 14 is elastically deformed, and when the first male terminal 20a is separated from the projecting piece 14, the projecting piece 14 returns to the original state. .

  As one example, the projecting piece 14 is formed by bending and deforming a rectangular metal plate. Specifically, the projecting piece 14 is formed on the first plate portion 14a connected to the front end portion of the first female body 10a of the first female terminal 10a on the first opening 11a side, and the front portion of the first plate portion 14a. And a connected second plate portion 14b.

That is, the 1st board part 14a inclines the connection part (the root part of the 1st board part 14a) of the 1st board part 14a and the 1st cylinder 12a as a 1st bending part. In the present embodiment, the front portion of the first plate portion 14a exceeds the cylindrical axis of the first cylindrical body 12a so that the first male terminal 20a inserted from the first insertion port 33a contacts the projecting piece 14. Exist in position.

  The second plate portion 14b is inclined in a direction in which the front portion (portion opposite to the first plate portion 14a) of the second plate portion 14b is away from the cylinder axis of the first cylindrical body 12a. That is, the 2nd board part 14b inclines the connection part of the 2nd board part 14b and the 1st board part 14a as a 2nd bending part.

  In the present embodiment, the first male terminal 20a inserted from the first insertion port 33a abuts in the vicinity of the connection portion (second bent portion) of the first plate portion 14a and the second plate portion 14b.

  Further, the width (plate width) of the protruding piece 14 is equal to or less than the width of the first cylindrical body 12 a. That is, the width of each of the first plate portion 14a and the second plate portion 14b is equal to or less than the cylinder diameter of the first cylindrical body 12a. Specifically, the projecting piece 14 exists in the region of the first opening 11 a of the first cylindrical body 12 a when viewed in the cylinder axial direction of the first cylindrical body 12 a.

[Male connector]
Next, the detailed configuration of the male connector 2 will be described with reference to FIGS. 4A to 4C.

  As described above, as shown in FIGS. 4A to 4C, the male connector 2 includes three male terminals 20a, 20b and 20c as a plurality of male terminals 20. Have.

  The first male terminal 20a, the second male terminal 20b, and the third male terminal 20c are conductive pins made of a conductive material. As an example, the 1st male terminal 20a, the 2nd male terminal 20b, and the 3rd male terminal 20c are the flat metal pins comprised by the metal plate. In the present embodiment, the first male terminal 20a, the second male terminal 20b, and the third male terminal 20c have the same shape and the same size.

  Each of the first male terminal 20a, the second male terminal 20b and the third male terminal 20c is electrically and mechanically connected to each of the first female terminal 10a, the second female terminal 10b and the third female terminal 10c. . Therefore, the first male terminal 20a is a ground terminal for grounding. The second male terminal 20b and the third male terminal 20c are power supply terminals for power supply. Specifically, the second male terminal 20b is a power supply terminal on the high voltage side, and the third male terminal 20c is a power supply terminal on the low voltage side.

  In the present embodiment, each male terminal 20 is connected to the terminal connection portion 21 which is a portion connected to each female terminal 10 by being inserted through the cylindrical body 12 of each female terminal 10, and to the circuit board 111. And a substrate connection portion 22 which is a portion.

  The terminal connection portion 21 is elongated and formed in a straight line so as to extend in the X-axis direction. The board connection portion 22 is formed to extend in the direction orthogonal to the longitudinal direction of the terminal connection portion 21 from the rear end portion of the terminal connection portion 21. The board connection portion 22 is bent in a step-like manner, and the tip end portion is soldered by the circuit board 111.

  In each male terminal 20, the tip end of the terminal connection portion 21 is formed in a shape in which the plate width narrows toward the tip. Specifically, the shape of the distal end portion of the terminal connection portion 21 is a tapered shape in which the plate width is gradually narrowed. Furthermore, the tip end portion of the terminal connection portion 21 is not only tapered in the plate width direction, but is also tapered in the plate thickness direction. That is, the tip end of the terminal connection portion 21 is formed in a shape in which the plate thickness is narrowed toward the tip. Specifically, the shape of the distal end portion of the terminal connection portion 21 is a tapered shape in which the plate width is gradually narrowed.

  The first male terminal 20 a, the second male terminal 20 b, and the third male terminal 20 c configured as described above are fixed to the main body 40.

  The main body 40 of the male connector 2 is an insulating housing that holds the male terminal 20 (the first male terminal 20a, the second male terminal 20b, and the third male terminal 20c). The main body 40 is, for example, a resin molded product made of a resin such as PBT. The material of the main body 40 is not limited to resin, and may be made of an insulating material other than resin.

  The main body 40 has a hollow portion 42 having an opening 41 facing the tip of the terminal connection portion 21 of the male terminal 20. In the present embodiment, the main body 40 has a plurality of hollow portions 42 corresponding to the plurality of male terminals 20 in a one-on-one manner. Specifically, the main body 40 has, as the cavity 42, a first cavity 42a having a first opening 41a facing the tip of the first male terminal 20a, and a second opening facing the tip of the second male terminal 20b. It has a second cavity 42b having 41b and a third cavity 42c having a third opening 41c facing the tip of the third male terminal 20c.

  The first hollow portion 42a, the second hollow portion 42b, and the third hollow portion 42c are formed in line in the Y-axis direction. Each of the first cavity 42a, the second cavity 42b, and the third cavity 42c has a substantially bottomed cylindrical shape, and has a space area surrounded by the bottom and four side walls. That is, between the first hollow portion 42a, the second hollow portion 42b, and the third hollow portion 42c, a partition wall is formed which divides adjacent space regions.

  The terminal connection portion 21 of the corresponding male terminal 20 is disposed in each hollow portion 42 so as to protrude from the bottom toward the opening 41. Therefore, the terminal connection portion 21 of each male terminal 20 is located in the cavity 42, and the side periphery is surrounded by the cavity 42. Thus, the terminal connection portion 21 of the male terminal 20 is not exposed to the outside of the main body 40. Therefore, even if the male terminal 20 is in an energized state, there is no possibility that the user directly touches the male terminal 20. Furthermore, the male terminal 20 can be protected by surrounding the male terminal 20 with the cavity 42. Thereby, since male terminal 20 does not contact other parts or a user, it can control that male terminal 20 is bent or damaged. The apexes of the end portions of the terminal connection portions 21 of the male terminals 20 are aligned at the same position in the horizontal direction.

  The hollow portion 42 is an insertion hole into which the main body 30 of the female connector 1 is inserted. That is, the hollow portion 42 functions as a housing portion for housing the main body 30 of the female connector 1. In the present embodiment, the protrusions 31 of the main body 30 of the female connector 1 are inserted into the hollow portions 42. Specifically, the first protrusion 31a is inserted into the first cavity 42a, the second protrusion 31b is inserted into the second cavity 42b, and the third protrusion is inserted into the third cavity 42c. The part 31c is inserted. That is, the openings 41 (the first opening 41a, the second opening 41b, and the third opening 41c) of the respective hollow portions 42 are insertion ports into which the projecting portions 31 of the female connector 1 are inserted. Thus, the main body 40 of the male connector 2 and the main body 30 of the female connector 1 are connected by inserting the protrusions 31 into the hollow portions 42.

  Further, a through hole 43 is provided on the side surface of the main body 40. In the present embodiment, the through hole 43 is provided on the side wall of the first hollow portion 42 a corresponding to the first male terminal 20 a which is an earth terminal.

  The through hole 43 functions as a release part for releasing the connected state of the female connector 1 and the male connector 2 and also functions as a connection maintaining part for maintaining the connected state of the female connector 1 and the male connector 2 Do.

  In the present embodiment, when the female connector 1 and the male connector 2 are connected, the claw portion 34 a of the female connector 1 is engaged with the through hole 43. Specifically, the claw portion 34 a is engaged with the through hole 43 such that the claw portion 34 a is hooked on the open end of the through hole 43.

[Method of connecting female connector and male connector]
Next, a method of connecting the female connector 1 and the male connector 2 will be described with reference to FIG. FIG. 7 is a view for explaining a method of connecting the female connector 1 and the male connector 2.

  As shown in (a) and (b) of FIG. 7, when connecting the female connector 1 and the male connector 2, the hollow portion 42 of the main body 40 of the male connector 2 has the protrusion 31 of the main body 30 of the female connector 1. Plug in.

  At this time, the female connector in the hollow portion 42 of the male connector 2 until the claw portion 34a of the arm portion 34 provided in the main body 30 of the female connector 1 is locked in the through hole 43 provided in the main body 40 of the male connector 2 Push in the protrusion 31 of 1.

  At this time, the arm portion 34 of the female connector 1 is elastically deformed while being pressed until the claw portion 34 a is locked in the through hole 43. For example, when the user holds the main body 30 of the female connector 1 and inserts the protrusion 31 into the cavity 42 of the male connector 2, the arm 34 can be elastically deformed by the pressure received from the side wall of the cavity 42.

  Thereafter, when the protrusion 31 is further pushed into the cavity 42, the claw 34 a of the arm 34 reaches the open end of the through hole 43. At this time, the pressure that the arm portion 34 receives from the hollow portion 42 is released, and the arm portion 34 spreads outward due to the spring restoring force by the resin elastic force and tries to return to the original state. As a result, the claws 34a are caught and locked in the through holes 43, and the connection between the female connector 1 and the male connector 2 is maintained.

  Thus, although the female connector 1 and the male connector 2 are connected, in the process of being connected, the female terminal 10 of the female connector 1 and the male terminal 20 of the male connector 2 are shown in FIGS. 8A to 8C. Connected through the following behavior. 8A to 8C show a state from the insertion of the female connector 1 into the male connector 2 to the contact between the female terminal 10 and the male terminal 20, and FIG. 8A shows three female terminals 10 and three A state before any contact with the male terminal 20, FIG. 8B shows a state when only the first female terminal 10a and the first male terminal 20a are in contact, FIG. 8C shows three female terminals 10 and three The state when all the male terminals 20 are in contact is shown.

  As shown in FIG. 8A, the female connector 1 is brought close to the male connector 2, and the protrusion 31 of the female connector 1 is inserted into the hollow 42 of the male connector 2. Thereby, the female terminal 10 of the female connector 1 approaches the male terminal 20 of the male connector 2. Specifically, each of the first female terminal 10a, the second female terminal 10b, and the third female terminal 10c approaches each other while facing each of the first male terminal 20a, the second male terminal 20b, and the third male terminal 20c. To go.

  As shown in FIG. 8B, when the protruding portion 31 of the female connector 1 is further inserted into the hollow portion 42 of the male connector 2, each male terminal 20 of the male connector 2 is inserted into the insertion port 33 of each protruding portion 31 of the female connector 1. Be inserted. Specifically, as shown in FIGS. 3A to 3C and FIGS. 4A to 4C, the first male terminal 20a is inserted into the first insertion port 33a of the first projecting portion 31a, and the second male terminal 20b is the second The third male terminal 20c is inserted into the second insertion port 33b of the protrusion 31b, and is inserted into the third insertion port 33c of the third protrusion 31c.

  At this time, as shown in the enlarged view of FIG. 8B, since the first female terminal 10a is provided with the projecting piece 14, the first female terminal 10a of the three female terminals 10 is firstly male terminal 20 ( It will contact the first male terminal 20a). That is, before the second male terminal 20b and the third male terminal 20c come into contact with the second female terminal 10b and the third female terminal 10c, the first male terminal 20a comes in contact with the first female terminal 10a. Specifically, the tip of the terminal connection portion 21 of the first male terminal 20a abuts on the surface of the second plate portion 14b of the projecting piece 14 of the first female terminal 10a. As a result, among the three female terminals 10 and the three male terminals 20, the first female terminal 10a, which is the ground terminal, and the first male terminal 20a first contact and conduct.

  As described above, in the female connector 1, when the first male terminal 20 a is inserted into the first insertion port 33 a of the first protrusion 31 a of the female connector 1, the tip of the first male terminal 20 a is the first female terminal 10 a. It is configured to be in contact with the projecting piece 14 of

  Then, when the tip of the first male terminal 20a contacts the projecting piece 14 of the first female terminal 10a, the conduction between the first female terminal 10a and the first male terminal 20a is completed. That is, the ground connection is completed. At this time, the second female terminal 10b and the second male terminal 20b are not in contact yet, and the third female terminal 10c and the third male terminal 20c are not in contact yet.

  Thereafter, as shown in FIG. 8C, when the projecting portion 31 of the female connector 1 is further pushed into the back of the hollow portion 42 of the male connector 2, each male terminal 20 is an opening 11 of the cylindrical body 12 of each female terminal 10. And is inserted into the cylindrical body 12 and advances toward the back of the cylindrical body 12. At this time, each male terminal 20 moves toward the back of the cylinder 12 while being held by the narrow portion 13 in the cylinder 12 of each female terminal 10.

  As described above, by holding each male terminal 20 at the narrow portion 13 in the cylindrical body 12 of each female terminal 10, the conduction between each male terminal 20 and each female terminal 10 is completed. Specifically, as shown in FIGS. 3A to 3C and 4A to 4C, the second male terminal 20b is held by the second narrow portion 13b in the second cylindrical body 12b of the second female terminal 10b. Thus, the second male terminal 20b and the second female terminal 10b are electrically connected, and the third male terminal 20c is held by the third narrow-width portion 13c in the third cylindrical body 12c of the third female terminal 10c. Then, the third male terminal 20c and the third female terminal 10c are electrically connected.

  On the other hand, for the first female terminal 10a and the first male terminal 20a, the conduction is completed when the first male terminal 20a contacts the projecting piece 14 (FIG. 8B), and the first male terminal 20a is the first female terminal. The projecting piece 14 continues to be in contact with the first male terminal 20a while advancing toward the back of the first cylindrical body 12a of 10a, but as shown in the enlarged view of FIG. 8C, the first male terminal 20a The first male terminal 20a and the first female terminal 10a are reliably conducted by being sandwiched by the first narrow-width portion 13a in the first cylindrical body 12a of the single female terminal 10a. That is, about the 1st female terminal 10a and the 1st male terminal 20a which are earth terminals, it is mutually conducting in two places of the projecting piece 14 and the 1st narrow part 13a.

  Then, when the tip end of the projection 31 of the female connector 1 reaches the bottom of the hollow 42 of the male connector 2, the connection between the female connector 1 and the male connector 2 is completed. As described above, the female connector 1 and the male connector 2 are electrically and mechanically connected.

  In addition, after female connector 1 and male connector 2 are connected, the connected state of female connector 1 and male connector 2 is released by removing claw portion 34a of female connector 1 from through hole 43 of male connector 2 can do. Specifically, the user holds the tab 34b of the female connector 1 and the main body 30 of the female connector 1 and elastically deforms the arm 34 so that the arm 34 and the main body 30 approach each other, thereby the claw 34a. Is removed from the through hole 43. Then, in this state, the female connector 1 can be removed from the male connector 2 by pulling out the projection 31 of the female connector 1 from the hollow portion 42 of the male connector 2. Thereby, the connection state of the female connector 1 and the male connector 2 can be released.

  Further, when releasing the connected state of the female connector 1 and the male connector 2, the first female terminal 10 a is provided with the projecting piece 14, so the third of the three female terminals 10 and the three male terminals 20 is the first. The one male terminal 20a and the first female terminal 10a can be brought into contact and conducted to the end. That is, when the first female terminal 10a and the first male terminal 20a are in a non-conductive state (non-contact state), the second female terminal 10b, the third female terminal 10c, the second male terminal 20b, and the third male terminal 20c is in a non-conductive state (non-contact state).

[Summary]
As mentioned above, in the female connector 1 in this Embodiment, the main body 30 holding the 1st female terminal 10a and the 2nd female terminal 10b behind the 1st insertion port 33a and the 2nd insertion port 33b is provided. And the 1st female terminal 10a has the protrusion piece 14 which protrudes toward the 1st insertion port 33a of the main body 30. As shown in FIG.

  With this configuration, as shown in FIGS. 8A to 8C, when connecting the female connector 1 and the male connector 2, the first female female connector 10b is not in contact with the second male female connector 20b. The terminal 10a and the first male terminal 20a can be brought into contact with each other.

  Thus, when the first female terminal 10a and the first male terminal 20a are earth terminals as in the present embodiment, when connecting the female connector 1 and the male connector 2, priority is given to the ground connection first. It can be carried out.

  Therefore, the power supply terminals (the second female terminal 10b and the third female terminal 10c) of the female terminal 10 and the power terminals (the second male terminal 20b and the third male terminal 20c) of the male terminal 20 (The first female terminal 10a) and the ground terminal (first male terminal 20a) of the male terminal 20 are connected before they are connected, thereby preventing an unexpected overcurrent from flowing in the electronic component it can.

  Moreover, when the connection between the female connector 1 and the male connector 2 is released by providing the projecting piece 14 on the first female terminal 10a, the contact state between the second female terminal 10b and the second male terminal 20b After the state is released, the contact state (conductive state) between the first female terminal 10a and the first male terminal 20a is released. That is, the ground connection can be maintained to the end.

  As mentioned above, according to the female connector 1 which concerns on this Embodiment, the connector which can perform highly reliable electrical connection with the male connector 2 is realizable. In addition, a female connector 1 conforming to a standard (IEC standard) established by the International Electrotechnical Commission (IEC) can also be realized.

  Moreover, in the present embodiment, the first female terminal 10a has the cylindrical first cylindrical body 12a having the first opening 11a into which the first male terminal 20a is inserted, and the projecting piece 14 is the first cylinder. It is provided in the front end part by the side of the 1st opening 11a of body 12a.

  With this configuration, it is possible to easily realize that the first female terminal 10a and the first male terminal 20a are brought into contact with each other before the second female terminal 10b and the second male terminal 20b come into contact with each other.

  Further, in the present embodiment, the protruding piece 14 has a leaf spring structure.

  With this configuration, even when the female connector 1 and the male connector 2 are repeatedly attached and detached, the shape of the projecting piece 14 returns to the original initial state. Thus, each time the female connector 1 and the male connector 2 are connected, the first female terminal 10a and the first male terminal 20a can be reliably brought into contact with each other first.

  Further, in the present embodiment, the protruding piece 14 has the first plate portion 14a connected to the front end portion of the first cylindrical body 12a on the first opening 11a side. And the 1st board part 14a inclines in the direction where the front part of the 1st board part 14a approaches the cylinder axis of the 1st barrel 12a.

  With this configuration, the first male terminal 20a inserted into the female connector 1 can be easily brought into contact with the first female terminal 10a.

  Further, in the present embodiment, the protruding piece 14 has the second plate portion 14 b connected to the front portion of the first plate portion 14 a. And the 2nd board part 14b inclines in the direction in which the front part of the 2nd board part 14b distances from the cylinder axis of the 1st cylinder 12a.

  With this configuration, a bent portion can be formed at the connection portion between the first plate portion 14a and the second plate portion 14b, so that a leaf spring structure can be easily formed on the projecting piece 14. Further, by providing the second plate portion 14b, the first male terminal 20a inserted into the female connector 1 slides in contact with the surface of the second plate portion 14b. It can be guided to a predetermined insertion path in the terminal 10a.

  Moreover, in the present embodiment, the width of the protruding piece 14 is equal to or less than the width of the first cylindrical body 12 a.

  With this configuration, the projecting piece 14 can be disposed using the existing storage portion 32 for storing the first female terminal 10a. That is, it is not necessary to separately form in the main body 30 a region (a hole portion) only for housing the projecting piece 14. Thereby, it can suppress that the cost of the female connector 1 increases more than necessary by providing the protrusion piece 14 in the 1st female terminal 10a.

  Further, in the present embodiment, the first female terminal 10a has the first narrow-width portion 13a provided behind the first opening 11a and sandwiching the first male terminal 20a, and the second female terminal 10b. Has a second narrow portion 13b provided on the back side of the second opening 11b and sandwiching the second male terminal 20b. The distance from the first opening 11a to the first narrow width portion 13a and the distance from the second opening 11b to the second narrow width portion 13b are substantially the same.

  With this configuration, the first female terminal 10a and the first male terminal 20a are first electrically conducted in the projecting piece 14, while the first female terminal 10a and the first in the first narrow width portion 13a and the second narrow width portion 13b. Reliable conduction with the male terminal 20a and reliable conduction between the second female terminal 10b and the second male terminal 20b can be secured. Thereby, the electrical connection between the female connector 1 and the male connector 2 can be performed with higher reliability.

  Further, in the present embodiment, the female connector 1 is used for the lighting apparatus 100.

  Thereby, the lighting fixture 100 in which the electrical connection between the female connector 1 and the male connector 2 is performed with high reliability can be realized.

  In particular, in the present embodiment, the male connector 2 is fixed to the circuit board 111 on the power supply side. Thereby, electrical connection can be performed with higher reliability.

(Modification)
As mentioned above, although this invention was demonstrated based on embodiment, this invention is not limited to the said embodiment.

  For example, in the above embodiment, one protruding piece 14 is formed at the end (opening end) of the first opening 11a of the first cylindrical body 12a of the first female terminal 10a. Two projecting pieces 14 may be formed at the end (opening end) of the first opening 11 a as in the case of one female terminal 10 aA. In this case, the two projecting pieces 14 may be disposed to face each other such that the connection portion (bent portion) of the first plate portion 14a and the second plate portion 14b faces each other.

  Moreover, in the said embodiment, although the protrusion piece 14 was comprised by the 1st board part 14a and the 2nd board part 14b, it does not restrict to this.

  For example, like the first female terminal 10aB shown in FIG. 10, the protruding piece 14B may be configured only by the first plate portion 14a. In this case, the first male terminal 20a inserted into the main body 30 of the female connector 1 contacts the tip of the first plate portion 14a of the projecting piece 14B, and the first plate portion is moved with the movement of the first male terminal 20a. The tip end portion 14a slides on the first male terminal 20a.

  Alternatively, as in the case of the first female terminal 10aC shown in FIG. 11, the projecting piece 14C may be configured by the first plate portion 14a, the second plate portion 14b, and the third plate portion 14c. In this case, the third plate portion 14c may be formed to be bent outward at a connection portion with the second plate portion 14b. With this configuration, it is possible to realize a protruding piece 14B in which the spring reaction force is improved more than the protruding piece 14 of the above embodiment.

  Moreover, in the said embodiment, although the protrusion piece 14 was integrally formed with the 1st female terminal 10a by pressing a metal plate, it does not restrict to this. For example, the protruding piece 14 may be a separate part, and the protruding piece 14 may be retrofitted to the first cylindrical body 12a of the first female terminal 10a by welding or the like.

  Moreover, in the said embodiment, although the hollow part 42 of the male connector 2 was formed only for the number of the male terminals 20, it does not restrict to this. For example, only one cavity 42 may be common to all the male terminals 20. In this case, the opening of the hollow portion 42 is also only one. Furthermore, in this case, the number of the projecting portions 31 of the female connector 1 may be three, but may be only one common to all the female terminals 10 that collectively accommodate the female terminals 10.

  Moreover, in the said embodiment, although the cylindrical body 12 of the female terminal 10 was made into the rectangular cylinder shape, it does not restrict to this.
