  In the conventional lever-type connector, the other side is pressed toward the female housing side from the connecting portion of the lever and turned to fit the male housing and the female housing, and the lever is moved in the opposite direction. By moving, the male housing is detached from the female housing. However, conversely, the lever is turned away from the female housing to fit the male housing and the female housing, and the lever is moved in the opposite direction to remove the male housing from the female housing. There are times when the workability is improved.

  The present invention has been made paying attention to such a point, and the object of the present invention is to fit a rotation fulcrum protrusion provided in the second housing into a guide groove of the lever provided in the first housing, and The two housings are fitted together by turning to the side away from the second housing, and the two housings are detached by turning in the opposite direction. It is another object of the present invention to provide a pair of connector housings having a temporary fitting structure capable of preventing and further visually confirming whether or not both housings are fitted.

  The pair of connector housings having the provisional fitting structure according to the present invention is provided with an insertion portion extending from the tip to the depth direction over a predetermined length when the depth direction, the thickness direction, and the width direction are orthogonal to each other. A housing chamber for housing the contact so that the contact portion is positioned in the vicinity of the end face of the tip substantially in the depth direction has a body provided through the depth direction, and a lever provided in the body. A first housing and a recess recessed from an end face of the front end substantially in the depth direction and having a recess that can be fitted or removed along the depth direction with the insertion portion of the main body of the first housing, and the second contact is a contact portion thereof And a second housing that is provided so as to pass through in the depth direction so that the storage chamber is positioned near the bottom surface of the concave portion, and the lever has a width side on both sides in the width direction of the main body. A guide groove is provided on the outer surface in the width direction so that the outer end reaches the outer peripheral edge to become a connection port and approaches the rotation center toward the inner end. Two guide members, and an operation member disposed on one side of the main body in the thickness direction and connecting the two guide members, and the connection ports of the two guide grooves are substantially along the depth direction. It is possible to rotate between a first position where the end face of the main body is directed in the direction in which the end face is directed, and a second position where the first end is rotated to the side farther from the end face of the main body than the first position. Rotation fulcrum protrusions protruding inward in the width direction are respectively provided on the walls on both sides in the width direction among the walls constituting the recesses of the second housing, and the first housing when the lever is in the first position. Insert the main body into the second When inserted into the recess of the bossing, the pivot fulcrum protrusion fits into the guide groove connection port, and then when the lever is pivoted to the second position, the pivot fulcrum protrusion is guided by the guide groove, thereby rotating in the guide groove. The engagement position with the movement fulcrum protrusion moves so as to approach the rotation center, and the insertion portion of the main body of the first housing is relatively pushed into the back of the concave portion of the second housing so that the two housings are fitted. The first housing includes an inner protruding piece protruding outward in the width direction at both ends of the main body in the width direction, and an outer protruding piece protruding outward in the width direction of the two guide members, When the insertion portion of the main body of the first housing is inserted into the recess of the second housing and the lever is at an intermediate position between the first position and the second position, the outer protruding piece is The two housings are temporarily fitted by hanging on the piece and the pivot fulcrum projection is hooked on the constituent wall of the guide groove, and then the lever is rotated to the first position side or pulled away from both housings. And the flexibility of the guide member allows the outer protruding piece to escape outward in the width direction and get over the inner protruding piece, whereby the lever reaches the first position and the two housings can be detached. The distance between the rotation center when the both housings are temporarily fitted to the contact point between the rotation fulcrum projection and the constituent wall of the guide groove, and the two housings are separated. The distance in the rotational radius direction from the center of rotation to the outer projecting piece is higher than the first torque that is the torque around the center of rotation generated by the reference value of the housing acting force that serves as a reference as a pulling force in the direction. The second torque, which is the torque around the center of rotation generated by the force that bends the guide member so that the outer protrusion escapes outward in the width direction and gets over the inner protrusion, and the second torque is A third torque which is a torque around the rotation center generated by a distance in the rotation radius direction from the rotation center to the operation member and an operation member action force reference value serving as a reference as a force for pulling the operation member toward the distal end side. Is set smaller than.

  The first contact is accommodated in the first housing, and the second contact is accommodated in the second housing. When these two housings are fitted, when the insertion portion of the main body of the first housing is inserted into the concave portion of the second housing when the lever is in the first position, the rotation fulcrum protrusion is formed in the guide groove. When the lever is turned to the second position after being fitted into the connection port, the rotation fulcrum protrusion is guided by the guide groove so that the engagement position of the guide groove with the rotation fulcrum protrusion approaches the rotation center. The insertion portion of the main body of the first housing is relatively pushed into the recess of the second housing, whereby the two housings are fitted. When the two housings are detached, the rotation fulcrum protrusion is guided by the guide groove when the lever is rotated from the second position to the first position, thereby engaging the rotation fulcrum protrusion in the guide groove. The position moves away from the rotation center, and the insertion portion of the main body of the first housing is relatively pulled toward the front from the back of the recess of the second housing, and then the insertion portion of the main body of the first housing is moved to the first position. When the two housings are pulled out from the recesses, the pivot fulcrum protrusions are disengaged from the connection openings of the guide grooves, whereby both the housings are detached.

  In that case, when the insertion portion of the main body of the first housing is inserted into the concave portion of the second housing and the lever is at an intermediate position between the first position and the second position, the outer protruding piece is The two housings are temporarily fitted by being hooked on the inner projecting piece and the pivot fulcrum projection on the constituent wall of the guide groove. Since the second torque is set to be larger than the first torque, both housings will not be detached unless pulled with a force exceeding the housing action force reference value in the direction in which both housings are detached. Withdrawal is prevented. Further, since the second torque is set to be smaller than the third torque, both the housings are detached as long as the operation member is pulled to the tip side with a force exceeding the operation member acting force reference value. Can be removed with certainty.

  Next, when the lever is rotated to the first position side or pulled in the direction of releasing both the housings, the outer projecting piece escapes outward in the width direction due to the flexibility of the guide member and gets over the inner projecting piece. As a result, the lever reaches the first position, and both housings can be detached. Further, since the relative position of both housings along the depth direction and the position of the lever in the main body of the first housing are related to the movement of the engagement position with the rotation fulcrum protrusion in the guide groove, the first housing It is possible to visually confirm whether or not the two housings are fitted according to the position of the lever in the main body.

  In the pair of connector housings having the temporary fitting structure according to the present invention, when the lever is in the first position, the guide groove is closer to the operation member than the rotation center in the thickness direction when the connection port is viewed from the width direction. Closely located and slightly bent toward the center of rotation on the slightly inner end side of the connection port, and when both housings are temporarily fitted, the rotation fulcrum protrusion is the bent portion in the guide groove When the two housings are pulled away from each other, the rotation fulcrum protrusion pushes the corners, and thus the flexibility of the guide member You may comprise so that an outer side protrusion piece may escape to the width direction outer side and may get over an inner side protrusion piece.

  In this way, since the torque acting on the lever is determined by the pulling force when the pivot fulcrum protrusion is applied to the corner portion, the force applied to the outer protruding piece is ensured, and the outer protruding piece is surely connected to the inner protruding portion. Get over the piece.

  The pair of connector housings having the temporary fitting structure of the present invention may be configured such that the first contact and the second contact are separated from each other when the two housings are temporarily fitted.

  If it does in this way, when both housings will be fitted after temporary fitting, the 1st contact and the 2nd contact will contact.

  The pair of connector housings having the temporary fitting structure according to the present invention is configured such that the two housings are fitted by turning the lever away from the second housing, and the two housings are detached by turning in the opposite direction. In addition, it is possible to prevent inadvertent disengagement by temporarily fitting before disengagement, and it is possible to visually check whether or not both housings are engaged.

  When the guide groove is bent in a substantially L shape and the two fulcrum protrusions push the corners when the two housings are temporarily fitted and then pulled away from the housing, The force applied to the projecting piece is ensured, and the lever can be brought to the first position by reliably moving the outer projecting piece over the inner projecting piece.

  When the first housing and the second contact are separated from each other when the two housings are temporarily fitted, the first contact and the second contact are formed when the two housings are fitted after the temporary fitting. Since the contacts come into contact with each other, the fitting can be confirmed by energization between both contacts.

Moreover, you may make it exhibit the stopper function in a 2nd position by applying the latching piece of a guide member to the receiving part of a main body.

  As shown in FIGS. 7 to 9, rotation fulcrum protrusions 330 protruding inward in the width direction are respectively provided on the walls on both sides in the width direction among the walls constituting the recess 310 of the second housing 300. The inner side in the width direction is the side close to the center in the width direction of the second housing, and the outer side in the width direction is the side far from the center in the width direction of the second housing. The rotation fulcrum protrusion 330 is formed so that the outer peripheral surface is circular when viewed from the width direction, and the centers of the circles coincide with each other in the two rotation fulcrum protrusions 330. The diameter of this circle is slightly smaller than the groove width of the guide groove 121b.

  As shown in FIG. 10, when the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300 when the lever 120 is in the first position, the rotation fulcrum protrusion 330 is formed. When the lever 120 is turned to the second position after being fitted into the connection port 121ba of the guide groove 121b, the turning fulcrum protrusion 330 is guided to the guide groove 121b as shown in FIG. 11 to FIG. The engagement position of the guide groove 121b with the rotation fulcrum protrusion 330 moves so as to approach the rotation center 113, and the insertion portion 111 of the main body 110 of the first housing 100 is relatively moved to the recess 310 of the second housing 300. It is configured so that both the housings are fitted into each other by being pushed into the back.

  As shown in FIGS. 2, 3, 5, 6, and 15, the first housing 100 includes an inner protrusion 131 that protrudes outward in the width direction at both ends in the width direction of the main body 110, and the second protrusion 100. One guide member 121 includes an outer protrusion 132 protruding inward in the width direction.

  When the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300 and the lever 120 is at an intermediate position between the first position and the second position, FIG. As shown in FIG. 16, the outer protrusion 132 is hooked on the inner protrusion 131, and the rotating fulcrum protrusion 330 is hooked on the constituent wall of the guide groove 121b as shown in FIG. Configured to match. As shown in FIG. 14, when the both housings are fitted and the lever 120 is in the second position, the lever 120 is slightly moved from the first position to the second position as shown in FIG. When the two housings are detached and the lever 120 is in the first position as shown in FIG. 1, the insertion portion 111 of the main body 110 of the first housing 100 is moved to the first position. 2 Inserted into the recess 310 of the housing 300 and is established when the lever 120 is rotated slightly to the second position side of the first position as shown in FIG. In this embodiment, as shown in FIG. 16, the inner protrusion 131 is provided with a second surface 131b facing the direction 2-1 and the outer protrusion 132 is provided in the 1-2 direction. A second surface 132b facing the opposite direction is provided. Then, when temporarily fitted, the outer protrusion 132 is delayed in the 2-1 direction with respect to the inner protrusion 131 because the second surface 132b of the outer protrusion 132 abuts against the second surface 131b of the inner protrusion 131. The rotation fulcrum protrusion 330 is hooked on the constituent wall of the guide groove 121b from the 2-1 direction delay side. When the two housings are temporarily fitted in this way, even if the two housings are pulled away with a certain amount of force, the pulling force is generated between the rotation fulcrum protrusion 330 and the constituent wall of the guide groove 121b. The outer projecting piece 132 strikes the inner projecting piece 131 from the delay side in the 2-1 direction and opposes the torque. The two housings are not easily detached until a tensile force is applied to 132 so as to apply a force necessary to move the inner protrusion 131 over the 2-1 direction.

  Next, when the lever 120 is rotated to the first position side or pulled in a direction to remove both housings, the outer protrusion 132 is moved outward in the width direction by the flexibility of the guide member 121 as shown in FIG. 1 to FIG. 3, the lever 120 reaches the first position so that the two housings can be detached, and the outer projecting piece 132 is used as the inner projecting piece. The lever 120 is configured to be prevented from turning to the second position side by being hooked from the opposite side to the case where both housings are temporarily fitted. In this embodiment, the inner protrusion 131 is provided with a first surface 131a facing the 1-2 direction opposite to the second surface 131b, and the outer protrusion 132 has a second surface 132b. The 1st surface 132a which faced the direction which opposes 2-1 direction is provided in the other side. The outer projecting piece 132 gets over the inner projecting piece 131 in the direction 2-1 and hits the first surface 131a of the inner projecting piece 131 from the delay side in the 1-2 direction by the first surface 132a. The projecting piece 132 is hooked on the inner projecting piece 131 to prevent the lever 120 from rotating to the second position, and the lever 120 is coupled with the stopper function at the first position by the locking piece 121c and the receiving portion 115. It is locked in the 1 position.

As shown in FIG. 11, the balance of torque applied to the lever 120 when the two housings are temporarily fitted is adjusted as follows. First, the distance D _{1 in} the rotation radius direction from the rotation center 113 when the two housings are temporarily fitted to the contact point between the rotation fulcrum protrusion 330 and the constituent wall of the guide groove 121b, the housing acting force reference value F ₁ and the first torque T ₁ the torque around rotation center caused by serving as a reference as a force pulling in a direction to leave the housing. Housing acting force reference value F ₁ is sized to the operator or user handle first connector C1 and the second connector C2 is assumed as a force to be exerted. Also, the guide member 121 is moved so that the distance D _{2 in} the rotation radius direction from the rotation center 113 to the outer protrusion 132 and the outer protrusion 132 escapes outward in the width direction and gets over the inner protrusion 131. A torque around the rotation center caused by the bending force F ₂ is defined as a second torque T ₂ . Further, the rotation caused by the distance D _{3 in} the rotation radius direction from the rotation center 113 to the operation member 122 and the operation member action force reference value F ₃ that serves as a reference as a force for pulling the operation member 122 toward the distal end side. A torque around the center is defined as a third torque T ₃ . Portion of the operating member 122 made at the end of the distance D ₃ is such that such sites fingers. The operating member acting force reference value F ₃ is an assumed magnitude as a force exerted by an operator or user who handles the first connector C1 and the second connector C2. At that time, the second torque T ₂ is set larger than the first torque T ₁ , and the second torque T ₂ is set smaller than the third torque T ₃ . That is, T ₁ <T ₂ <T ₃ is set.

  As shown in FIGS. 1, 2, and 4, the guide groove 121 b is operated when the connection port 121 ba is operated more than the rotation center 113 in the thickness direction when viewed from the width direction when the lever 120 is in the first position. It is located near the member 122 and is bent in a substantially L shape toward the center of rotation slightly on the inner end side of the connection port 121ba. As shown in FIG. 11, when both housings are temporarily fitted, the rotation fulcrum protrusion 330 is hooked on the inner end side of the corner portion 121bb on the inner peripheral side of the bent portion in the guide groove 121b. When the two housings are pulled away from each other, the rotation fulcrum protrusion 330 pushes the corner portion 121bb, and the flexibility of the guide member 121 causes the outer protrusion 132 to escape outward in the width direction. It is configured to get over the protruding piece 131.

  As shown in FIGS. 7 to 9, the second housing 300 is provided with two guide pieces 341. The guide piece 341 rises in the thickness direction from the inner surface of one wall in the thickness direction among the walls constituting the recess 310 of the second housing 300 and extends in the depth direction. As shown in FIG. 16, when the insertion part 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300, the two guide pieces 341 are replaced with the two inner protrusions. When the lever 120 is rotated from the position where both housings are temporarily fitted to the first position, the guide member 121 is bent to cause the two The two outer protruding pieces 132 that have passed over the inner protruding pieces 131 in the width direction are received by the two guide pieces 341, and the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recessed portion of the second housing 300. As shown in FIG. 15, when the guide member 121 is restored, the two outer protruding pieces 132 are moved toward one side in the thickness direction of the two inner protruding pieces 131 as shown in FIG. The respective stored the two outer projecting piece 132 has two inner protrusion 131, and configured to take from the opposite side of the when the two housings are provisionally fitted.

In this embodiment, the guide piece 341 has a first surface 131 a with respect to the inner protrusion 131 when the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300. It is provided so that it may contact the surface of the front end side of the depth direction in the outer side protrusion piece 132 which is located in the 1st surface 131a. The surface on the distal end side in the depth direction of the outer protrusion 132 is chamfered so as to be directed inward in the width direction by, for example, about 45 degrees from the direction in the rotation radius direction of the lever 120, and thus the insertion portion 111. 16 is inserted into the recess 310, the guide piece 341 pushes the guide member 121 outward in the width direction and deflects the guide member 121 outward in the width direction, and as shown in FIG. Further, the rotation of the lever 120 is released so that the inner projecting piece 131 can be overcome in the 1-2 direction. With this embodiment, the chamfering angle of the surface on the distal end side in the depth direction of the outer protruding piece is not limitedly interpreted, and this surface may not be chamfered. As the insertion portion is inserted into the recess, the guide piece may be configured to cut into the gap between the main body of the first housing and the guide member.

  When the two housings are temporarily fitted, the first contact 200 and the second contact 400 are separated from each other and are configured not to contact each other.

  The main body 110, the lever 120, and the second housing 300 of the first housing 100 are provided symmetrically with respect to the center in the width direction. However, the pair of connector housings having the temporary fitting structure of the present invention includes an embodiment in which any one of the main body, the lever, and the second housing of the first housing is provided asymmetrically.

  Next, the operation and effect of the pair of connector housings having the temporary fitting structure of this embodiment will be described. The first contact 200 is accommodated in the first housing 100 as the first connector C1, and the second contact 400 is accommodated in the second housing 300 as the second connector C2. When the two housings are fitted to fit both connectors, the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300 when the lever 120 is in the first position. When inserted, the rotation fulcrum protrusion 330 fits into the connection port 121ba of the guide groove 121b, and then the rotation fulcrum protrusion 330 is guided by the guide groove 121b when the lever 120 is rotated to the second position. The engagement position of the rotation fulcrum protrusion 330 at 121 b moves so as to approach the rotation center 113, and the insertion portion 111 of the main body 110 of the first housing 100 moves relatively deep into the recess 310 of the second housing 300. The two housings are fitted together by being pushed in. When the two housings are detached, when the lever 120 is rotated from the second position to the first position, the rotation fulcrum protrusion 330 is guided by the guide groove 121b, whereby the rotation fulcrum protrusion in the guide groove 121b is achieved. 330 is moved away from the rotation center 113, and the insertion portion 111 of the main body 110 of the first housing 100 is relatively pulled from the back of the recess 310 of the second housing 300 to the front, and then When the insertion portion 111 of the main body 110 of the first housing 100 is pulled out from the recess 310 of the second housing 300, the rotation fulcrum protrusion 330 is detached from the connection port 121ba of the guide groove 121b, and thereby both the housings are detached.

In that case, when the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300 and the lever 120 is at an intermediate position between the first position and the second position, The outer protrusion 132 is hooked on the inner protrusion 131, and the rotation fulcrum protrusion 330 is hooked on the constituent wall of the guide groove 121b, whereby the two housings are temporarily fitted. Since the second torque T ₂ is set to be larger than the first torque T ₁ , the two housings will not be detached unless they are pulled with a force exceeding the housing action force reference value F ₁ in the direction in which the two housings are separated. Therefore, inadvertent withdrawal is prevented. In addition, since the second torque T ₂ is set to be smaller than the third torque T _3, both housings can be moved as long as the operation member 122 is pulled to the distal end with a force exceeding the operation member acting force reference value F _3. Since it separates, both housings can be reliably separated.

  Next, when the lever 120 is rotated to the first position side or pulled in the direction of releasing both the housings, the outer protruding piece 132 escapes outward in the width direction due to the flexibility of the guide member 121, and the inner protruding piece 131. Thus, the lever 120 reaches the first position so that the two housings can be detached, and the outer projecting piece 132 and the inner projecting piece 131 are opposite to the case where both housings are temporarily fitted. The lever 120 is prevented from rotating to the second position side. Since the two housings are detached after the lever 120 is locked in the first position in this way, the first housing 100 is held with the lever 120 held in the first position when the two housings are next fitted. Since the insertion portion 111 of the main body 110 is inserted into the recess 310 of the second housing 300, the rotation fulcrum protrusion 330 fits easily and reliably into the connection port 121ba of the guide groove 121b. Therefore, the fitting operation of both housings is performed smoothly. Further, the relative position of both housings along the depth direction and the position of the lever 120 in the main body 110 of the first housing 100 are related to the movement of the engagement position with the rotation fulcrum protrusion 330 in the guide groove 121b. Therefore, it is possible to visually confirm whether or not both housings are fitted according to the position of the lever 120 in the main body 110 of the first housing 100.

  Thus, in this embodiment, when the lever 120 reaches the first position, the lever 120 is locked to the first position in combination with the stopper function at the first position by the locking piece 121c and the receiving portion 115. However, the present invention includes an embodiment in which the stopper function at the first position is not provided and the lever is not locked at the first position even when the lever reaches the first position.

  The guide groove in the pair of connector housings having the temporary fitting structure according to the present invention has an outer end that reaches the outer peripheral edge as a connection port on the outer surface in the width direction of the guide member, and approaches the rotation center as it goes to the inner end. What is necessary is just to be provided. Among such various embodiments, the pair of connector housings having the provisional fitting structure of the above embodiment is such that the guide groove 121b is connected when viewed from the width direction when the lever 120 is in the first position. The opening 121ba is positioned closer to the operation member 122 than the rotation center 113 in the thickness direction, and is bent in a substantially L shape toward the rotation center 113 slightly on the inner end side of the connection port 121ba. When fitted, the rotation fulcrum protrusion 330 is hooked on the inner end side from the corner portion 121bb on the inner peripheral side of the bent portion in the guide groove 121b, and when the two housings are pulled in the direction of detachment, When the turning fulcrum protrusion 330 presses the corner 121bb, the outer protrusion 132 escapes outward in the width direction due to the flexibility of the guide member 121, and the inner protrusion 13 It was configured to overcome. In this way, the torque applied to the lever 120 by the pulling force is determined by the rotation fulcrum protrusion 330 being applied to the corner 121bb, so that the force applied to the outer protrusion 132 is ensured, and the outer protrusion 132 is secured. However, the lever 120 can be moved to the first position by reliably getting over the inner protrusion 131.

  The pair of connector housings having the provisional fitting structure of the present invention includes an embodiment in which no guide piece is provided. Among such various embodiments, the pair of connector housings having the provisional fitting structure of the above embodiment includes an inner surface of one wall in the thickness direction among the walls constituting the recess 310 of the second housing 300. When two guide pieces 341 rising in the thickness direction and extending in the depth direction are provided, and the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300 The two guide pieces 341 are respectively inserted on one side in the thickness direction of the two inner projecting pieces 131, and the lever 120 is rotated from the position when both housings are temporarily fitted to the first position. Then, the two outer protrusions 132 that have passed over the two inner protrusions 131 in the width direction by bending of the guide member 121 are received by the two guide pieces 341. When the insertion portion 111 of the main body 110 of the first housing 100 is removed from the recess 310 of the second housing 300, the guide member 121 is restored, so that the two outer protrusions 132 become the thickness of the two inner protrusions 131. The two outer protruding pieces 132 are respectively stored in one side in the vertical direction and are configured to be hooked on the two inner protruding pieces 131 from the side opposite to when both housings are temporarily fitted. By doing so, the resistance force when the lever 120 is rotated from the position when both the housings are temporarily fitted to the first position is relieved, so that the operability can be improved. Further, when the insertion portion 111 of the main body 110 of the first housing 100 is inserted into the recess 310 of the second housing 300, the two guide pieces 341 are placed on one side in the thickness direction of the two inner protrusions 131. Each of the two guide members 121 is bent and the two outer protrusions 132 are pushed outward in the width direction so that the two outer protrusions 132 can be passed over the two inner protrusions 131, respectively. It was comprised so that rotation prevention of the lever 120 might be cancelled | released. In this way, the fitting operation of both housings is performed smoothly.

  The pair of connector housings having the temporary fitting structure of the present invention may be configured such that the first contact and the second contact come into contact when both housings are temporarily fitted. Among such various embodiments, the pair of connector housings having the provisional fitting structure of the above embodiment has the first contact 200 and the second contact 400 when the two housings are provisionally fitted. It comprised so that it might space apart. In this way, the first contact 200 and the second contact 400 come into contact when the two housings are fitted after temporary fitting. Therefore, fitting can be confirmed by energization between both contacts.
