It is a figure which shows these connection states, Comprising: (a) is the top view which looked at one part in cross section, (b) is a side view.

  First, the male terminal 14 will be described.

  As shown in FIGS. 4 and 5, the male terminal 14 includes a terminal main body 51 and a movable contact 52 separate from the terminal main body 51.

  The terminal main body 51 and the movable contact 52 are formed by pressing a metal plate made of copper, copper alloy, stainless steel, or aluminum, and it is preferable that the surface is subjected to tin plating for improving electrical connection performance.

  The terminal body 51 has a crimping portion 53 on the rear end side and an electrical connection portion 54 on the tip end side.

  The crimping portion 53 on the rear end side includes a conductor crimping portion 53a and a covering crimping portion 53b, and the electric wire 16 is crimped and connected to the crimping portion 53.

  Specifically, the conductor 16b exposed from the coating 16a at the end of the electric wire 16 is crimped to the conductor crimping portion 53a, and the coating 16a of the electric wire 16 is crimped to the coating crimping portion 53b.

  The electrical connection portion 54 on the distal end side has a sliding cylinder 55 formed in a square cylinder shape. The sliding cylinder 55 has a sliding hole 56 having a rectangular shape in sectional view along the axial direction, and the movable contact 52 is accommodated in the sliding hole 56. The sliding cylinder 55 is formed with a pair of engaging holes 57 on both side surfaces thereof.

  The movable contact 52 accommodated in the sliding cylinder 55 includes fixed plate portions 61 arranged in parallel to each other, spring portions 62a and 62b extending from the fixed plate portions 61 toward the distal end side, and these And a contact tab 63 for connecting the tips of the spring portions 62a, 62b.

  In the fixed plate portion 61, both side portions 61a projecting sideways are engaged from the inner surface side with engagement holes 57 formed in the sliding cylinder 55. Accordingly, the rear end of the movable contact 52 is fixed to the sliding cylinder 55, and movement in the axial direction with respect to the sliding cylinder 55 is restricted.

  The spring portions 62a and 62b are formed in a linear shape, and are formed into a waveform having a plurality of bent portions 66 along the axial direction. These spring portions 62a and 62b are opposite in phase to each other when viewed from the side, whereby the bent portions 66 are alternately arranged.

  The contact tab 63 is curved in a U shape so as to protrude toward the tip end, and spring portions 62a and 62b are connected to both sides thereof.

  Further, the male terminal 15 has engaging protrusions (engaging means) 71 formed on both side portions in the vicinity of the tip of the sliding cylinder 55 constituting the electrical connecting portion 54.

  Next, the female terminal 15 will be described. Note that the female terminal 15 has substantially the same structure as the male terminal 14, and here, a different part from the male terminal 14 will be described.

  As shown in FIGS. 6 and 7, in the female terminal 15, engagement hooks (engagement means) 75 are provided on both side portions in the vicinity of the tip of the slide cylinder 55 instead of the engagement protrusions 71. . These engagement hooks 75 are fixed to both side surfaces of the sliding cylinder 55 and extend from the tip of the electrical connection portion 54. These engagement hooks 75 are formed in a plate shape, and an engagement notch (engagement means) 76 is formed on the lower side thereof.

  Here, in order to manufacture the movable contact 52 provided on the male terminal 14 and the female terminal 15, as shown in FIG. 8, first, a metal plate made of copper, copper alloy, stainless steel, or aluminum is punched out. The spring portions 62a and 62b having a waveform in a plan view are formed between the plate portion that becomes the contact tab 63 and the fixed plate portion 61.

  The connection position A of the spring portions 62 a and 62 b in the contact tab 63 is point-symmetric with respect to the center point O of the contact tab 63. Further, the corrugated spring portions 62a and 62b are formed into waveforms having mutually opposite phases.

  Then, the metal plate punched as described above is bent in the same direction with the plate portion serving as the contact tab 63 as a boundary, and the contact tab 63 is bent in a U-shape, whereby the spring is moved to the rear end side of the contact tab 63. The parts 62a and 62b are extended in parallel.

  As shown in FIGS. 9A and 9B, the male terminal 14 and the female terminal 15 have the engagement notch 76 of the engagement hook 75 of the female terminal 15 engaged with the engagement protrusion 71 of the male terminal 14. By joining, they are connected to each other.

  The male terminal 14 and the female terminal 15 connected in this way are brought into contact with the contact tabs 63 of the respective movable contacts 52, and against the urging force of the spring portions 62a and 62b, respectively, in the sliding holes 56. Pushed in. As a result, the contact tabs 63 of the male terminal 14 and the female terminal 15 are pressed against and brought into contact with each other by the urging force of the spring portions 62a and 62b, and are very well conducted by the contact pressure.

  Here, since the connection position A of the spring portions 62a and 62b in the contact tab 63 is a point-symmetrical position with respect to the center point O of the contact tab 63, the movable contact 52 that is slid by being pressed against the connection partner is Twist and tilt during sliding are minimized. Thereby, the malfunction that the contact surface with the other party of the contact tab 63 inclines is eliminated.

  Further, since the spring portions 62a and 62b of the movable contact 52 are formed in waveforms having phases opposite to each other in a side view, the urging force of the spring portions 62a and 62b acts on the contact tab 63 in a balanced manner. To do.

  Next, based on the diagram showing the connection process between the male housing and the female housing shown in FIGS. 10 to 19 in the case of connecting the male housing 12 provided with the male terminal 14 and the female housing 13 provided with the female terminal 15. I will explain.

  In order to connect the male housing 12 and the female housing 13, first, as shown in FIGS. 10A and 10B, the one end 13 a side of the female housing 13 is put into the accommodation space S of the male housing 12 and locked. The piece 47 is inserted into the lower side of the support shaft 33 so that the female housing 13 is rotatable with respect to the male housing 12 about the support shaft 33.

  In this state, the female housing 13 is rotated in the direction of the bottom plate portion 31 of the housing portion 22 of the male housing 12 (in the direction of arrow X in FIG. 10B), and the female housing 13 is pushed into the housing space S of the male housing 12. .

  Then, as shown in FIGS. 11A to 11C, the protruding portion 49 of the female housing 13 enters the inner surface side of the side wall portion 32 of the male housing 12, and the tapered surface 50 of the protruding portion 49 is formed on the side wall portion 32. It slides in contact with the tapered surface 36. Thereby, the side wall 32 is gradually elastically deformed outward.

  Further, when the female housing 13 is pushed into the accommodation space S of the male housing 12, the joint surface 45 of the female housing 13 is lateral to the joint surface 25 of the male housing 12, as shown in FIGS. As shown in FIG. 13, the engagement hook 75 of the female terminal 15 gradually approaches the engagement protrusion 71 formed on the male terminal 14 of the male housing 12 from above.

  At this time, as shown in FIGS. 14A and 14B and FIG. 15, the contact tabs 63 of the movable contacts 52 of the male terminal 14 of the male housing 12 and the female terminal 15 of the female housing 13 are slid. It comes into contact with each other and is gradually pushed into the sliding hole 56 against the urging force of the spring portions 62a and 62b.

  When the female housing 13 is further pushed into the housing space S of the male housing 12 from this state, the protrusion 49 of the female housing 13 enters the engagement hole 35 beyond the tapered surface 36 of the side wall 32 of the male housing 12. Then, the side wall part 32 elastically deformed to the outside is restored and returned to the inside, so that the protrusion 49 is reliably engaged with the engagement hole 35, and the female housing 13 is connected to the male housing 12. It is locked in a state of being securely accommodated in the 12 accommodating spaces S. Accordingly, as shown in FIGS. 16A and 16B, the butting surfaces 46 a and 46 b of the joining surface 45 of the female housing 13 are butted against the butting surfaces 26 a and 26 b of the joining surface 25 of the male housing 12. .

  Then, as shown in FIG. 17, the engagement notch 76 of the engagement hook 75 of the female terminal 15 is engaged with the engagement protrusion 71 formed on the male terminal 14 of the male housing 12, so that the male terminal 14 and the female The terminals 15 are arranged in a straight line and are connected to each other.

  At this time, the reaction force of the urging force of the spring portions 62a and 62b generated when the contact tabs 63 are pressed against each other is an engagement means composed of an engagement protrusion 71 and an engagement hook 75 for engaging the terminal bodies 51 with each other. Will be accepted. Accordingly, the male housing 12 that holds the male terminal 14 and the female terminal 15, the lances 24 and 44 of the female housing 13, the support shaft 33 of the male housing 12 that supports the female housing 13, or the engagement of the male housing 12 that engages with each other. The reaction force of the urging force of the spring portions 62a and 62b does not act on the hole 35 and the protrusion 49 of the female housing 13.

  In this state, as shown in FIGS. 18A, 18B, and 19, the contact tabs 63 of the movable contacts 52 of the male terminal 14 and the female terminal 15 are brought into contact with each other, and the spring portions 62a, 62a, Each is pushed into the sliding hole 56 against the urging force of 62b. As a result, the contact tabs 63 of the male terminal 14 and the female terminal 15 are pressed against and brought into contact with each other by the urging force of the spring portions 62a and 62b, and are very well conducted by the contact pressure.

  As described above, according to the connection terminal including the male terminal 14 and the female terminal 15 according to the embodiment, the reaction force of the urging force of the spring portions 62a and 62b generated when the contact tabs 63 are pressed against each other is obtained. The engaging means including the engaging protrusion 71 and the engaging hook 75 that engage the terminal bodies 51 can be received. As a result, the creep generated by the reaction force of the urging force of the spring portions 62a and 62b is compared with the case where the reaction force when the contact tabs 63 are pressed is received by the lance of the resin housing or the lock portion of the housings. The contact load can be prevented from decreasing due to the damage of the contact tab 63, and the conductive connection state of the contact tab 63 can be maintained over a long period of time.

  Then, according to the connector 11 having the male terminal 14 and the female terminal 15 described above, the reaction force of the urging forces of the spring portions 62a and 62b generated when the contact tabs 63 are pressed against each other is applied to the terminal bodies 51. Since the male terminal 14 and the female terminal 15 received by the engaging means composed of the engaging protrusion 71 and the engaging hook 75 are held by the male housing 12 and the female housing 13, respectively, the male housing 12 and the female housing 13 are retained. The action of the reaction force of the urging force to the can be eliminated. Thereby, the fall of the contact load by damage to the resin-made male housing 12 and the female housing 13 can be prevented, and the favorable conduction | electrical_connection state of the contact tab 63 can be maintained over a long term.

  In particular, by rotating the female housing 13 around the support shaft 33 and sliding and joining the joint surface 25 of the male housing 12 and the joint surface 45 of the female housing 13, the male terminal 14 The contact tabs 63 of the female terminal 15 can be brought into sliding contact with each other, and the engagement notches 76 of the engagement hooks 75 are engaged with the engagement protrusions 71 so that the contact tabs 63 are electrically connected. Can be maintained in a state. Further, even if an oxide film is formed on the surface of the contact tab 63, when the contact tabs 63 are brought into sliding contact with each other, the oxide film can be removed, and a good conductive connection between the contact tabs 63 is obtained. The state can be obtained.

  In the above-described embodiment, the female housing 13 is rotated around the support shaft 33, and the joining surface 25 of the male housing 12 and the joining surface 45 of the female housing 13 are slid to face each other. As long as the joint surface 25 of the male housing 12 and the joint surface 45 of the female housing 13 slide relative to each other, the method is not limited to the method by rotating the female housing 13. For example, it is good also as a structure which joins the male housing 12 and the female housing 13 by translating and fitting the female housing 13 from the side with respect to the accommodation space S of the accommodating part 22 of the male housing 12. . Also in this case, the joint surface 25 of the male housing 12 and the joint surface 45 of the female housing 13 are slid relative to each other.

  The present invention is not limited to the above-described embodiments, and modifications, improvements, etc. can be made as appropriate.
