Description

  The present invention relates to a low-fitting connector that allows a male-female connector, at least one of which is composed of a plurality of connectors, to be fitted or released simultaneously by a turning operation of a lever.

  Many structures have been disclosed for a so-called lever-type low-fitting connector that has a connector structure that holds a lever and that allows the one connector to be fitted to the other connector with a low fitting force by rotating the lever. ing.

  For example, Patent Document 1 discloses the following contents. Specifically, one connector has a structure in which a lever is accommodated in a central portion in the width direction, a rotation shaft and a flexible arm are devised in the accommodation space, and the lever can be temporarily fixed by these. Then, the lever is attached to the connector, the lever temporary locking state is released by the fitting operation with the other connector, and the lever end is engaged with the engaging portion of the other connector and the lever is rotated. Thus, the male and female connectors are fitted. As a result, the lever can be prevented from falling off from the connector, and the handleability during parts transportation is also improved.

  For example, Patent Document 2 discloses the following contents. Specifically, as in Patent Document 1, a structure is employed in which a lever is accommodated and temporarily fixed at the center in the width direction of one connector. Then, after the male and female connectors are fitted to a predetermined amount and temporarily held, the levers are rotated so that the connectors are completely fitted. On the other hand, it differs from the disclosure of Patent Document 1 in the structure of the lever details. As a result, the connector can be miniaturized and the connector fitting operation can be performed efficiently and in a short time.

  Patent Document 3 discloses the following contents. Specifically, as in the disclosure of Patent Document 1 and Patent Document 2, a lever is provided at the center in the width direction of one connector, but a swing guide portion and a swing fulcrum portion are provided on the lever. On the other hand, the connector that houses the lever has a structure in which a linear groove is provided so that the swing guide portion and the swing fulcrum portion can swing. As a result, the stability of the connector fitting and mating release is improved by preventing the lever moving in the slit from moving and falling off.

JP 2002-117932 A (page 3-4, FIG. 1) (Japanese Patent Laid-Open No. 2003-234146, page 3-4, FIG. 2) JP 2000-228245 A (page 4-5, FIG. 1)

  Such a connector is designed so that after a plurality of connectors are inserted into the connector holder, the lever is rotated to be engaged with the mating connector at a time, so that a certain connector is half inserted into the connector holder. The connectors may be fitted together without noticing. If it can be recognized that any of the connectors is in the half-inserted state in the connector holder, the connector can be returned to the normal inserted state before the levers are rotated to engage the connectors. In addition, when the terminal is half-inserted into the connector, if such a half-inserted state of the connector into the connector holder occurs positively, the terminal can be connected to the connector by checking the half-inserted state of the connector. It can be judged as half insertion. Also, when inserting a plurality of connectors into the connector holder, the lever may become obstructive and difficult to insert, so the connectors can be inserted into the connector holder without interfering with the lever. It is also necessary to improve efficiency.

  An object of the present invention is a lever-type low-fitting connector in which at least one of male and female connectors is composed of a plurality of connectors, and the plurality of connectors are fitted to the mating connector at once via a lever. A lever-type low-fitting connector that can detect the half-insertion state of the connector and the half-insertion of the terminal into the connector, and facilitates connector fitting work by preventing the lever from interfering when each connector is inserted into the connector holder. It is to provide.

In order to solve the above-mentioned problem, the lever type low fitting connector according to the present invention is:

After the connector is inserted into the connector holder at the second temporary locking position of the lever, the lever is released from the second temporary locking position by further inserting the connector holder into the mating connector. Then, it is further rotated to perform connector fitting.

  When fitting a plurality of connectors to the mating connector at a time via a lever, it is possible to determine whether or not the plurality of connectors are correctly inserted into the connector holder by the connector insertion detection protrusion provided in the connector holder in advance. By rotating the lever, the plurality of connectors can be securely fitted to the mating connector.

Moreover, it can prevent that a male-female connector fits in a terminal half-inserted state by providing this terminal insertion detection piece in a some connector.

Further, the plurality of connectors, at least one connector, the first provisional locking position of the partial locking position of the two positions, can be inserted without interfering with the lever, the other of the at least one connector 2 in a second temporary lock position of the partial locking position location, it has become possible to insert the connector holder without interfering with the lever, the lever will interfere when inserting a plurality of connectors in the connector holder Therefore, workability is improved without interfering with connector insertion.

  According to the lever-type low-fitting connector according to the present invention, it is possible to reliably detect the half-insertion state of each connector into the connector holder and the half-insertion state of terminals into a plurality of connectors, and all the connectors are correctly inserted into the connector holder. In this state, the lever can be rotated to perform connector fitting at a time.

Further, the plurality of connectors, at least one connector, the first provisional locking position of the partial locking position of the two positions, can be inserted without interfering with the lever, the other of the at least one connector 2 In the second temporary locking position of the locations, the lever can be inserted into the connector holder without interfering with the lever so that the lever does not get in the way when inserting each connector into the connector holder. In this way, the connector fitting operation is facilitated.

  Hereinafter, the lever type low fitting connector 1 concerning one embodiment of the present invention is explained based on a drawing.

  A lever-type low-fitting connector 1 according to an embodiment of the present invention includes a female connector 30 and a laminated connector 40, a connector holder 10 that can hold the female connector 30 and the laminated connector 40, and a connection to the connector holder 10. It consists of a lever 20 assembled in a movable manner, and a single male connector 50 that can be fitted to a plurality of female connectors 30 and laminated connectors 40.

  Each of these components will be described in detail below. First, the connector holder 10 will be described. 1 to 4 are perspective views showing the connector holder 10. FIG. 2 shows a II-II cross section of FIG. FIG. 3 is a perspective view of one of the two types of connector holders 10 provided for preventing erroneous fitting as viewed from below. FIG. 4 is a perspective view of the other of the two types of connector holders 10 provided for preventing erroneous fitting, as viewed from below.

  The connector holder 10 is made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long period of time, and holds a pair of first connectors arranged in parallel so that two female connectors 30 can be attached. Part 11 and a second connector holding part 12 to which one laminated connector 40 can be attached. In addition, a lever housing groove 14 capable of housing a lever 20 described later is formed in the central portion of the pair of first connector holding portions 11, and a single plate-like lever 20 can be attached to this portion. ing.

  As shown in FIG. 2, a lever holding shaft 14a for assembling the lever 20 protrudes from one wall portion inside the lever receiving groove and is spaced apart by a certain distance on the side of the lever holding shaft 14a. A lever temporary locking pin 14b for locking the lever 20 at the first temporary locking position and the second temporary locking position protrudes from the position. The lever holding shaft 14a is formed with a tapered portion 14t on the shaft front end surface so that the lever 20 can be easily attached. The tapered portion 14t is formed such that the height of the lever holding shaft 14a decreases as the semicircular portion on the lever receiving groove opening side of the connector holder 10 into which the lever 20 is inserted moves toward the lever receiving groove opening. ing. Thus, when the lever 20 is pushed into the lever receiving groove 14, a part of the lever 20 gets over the lever holding shaft 14a, and the lever 20 is connected to the connector in a state where the rotation shaft hole 22 of the lever 20 and the lever holding shaft 14a are engaged. The holder 10 can be attached. A cantilever-like lever locking claw 14c for fixing the lever 20 at the second temporary locking position is provided on the side of the lever receiving groove of the connector holder 10 with its free end at the lever of the lever receiving groove 14. It is formed so as to face the insertion opening.

  In addition, since a plurality (two in this embodiment) of the connector holders 10 are fitted to the male connector 50, two connector holders 10 are provided between the first connector holding part 11 and the second connector holding part 12. A holder miscoupling prevention groove 15 is formed to prevent the connector holder 10 from being miscoupled to the male connector 50 in the left-right reversed state. The holder miscoupling prevention groove 15 is formed from both side surfaces of the connector holder 10 toward the center of the connector holder 10, and the groove cross-sectional shape is asymmetric with respect to the arrangement direction of the connector holding portions 11 and 12. Yes. In addition, the misbonding prevention groove 15 is formed with a fitting temporary locking piece 15a substantially at the center in the groove forming direction (see FIGS. 5 and 6), whereby the connector holder 10 is inserted into the male connector 50 described later. At this time, the connector holder 10 can be temporarily locked to the male connector 50.

A plurality of connector engaging protrusions (insertion detection protrusions) 17 are formed in parallel on the lower part of the inner wall on the center side of the first connector holding part 11, and the female connector 30 is inserted into the first connector holding part 11. When this is done, the connector engaging projection 17 acts as a retainer on the female connector 30. That is, if the terminal is left half inserted into the female connector 30, the female connector 30 cannot be completely inserted into the first connector holding portion 11 of the connector holder 10, and the terminal half insertion state into the female connector 30 is detected. It is like that. Further, the first connector holding portion 11 is formed with a pair of holder locking pieces 11 a for locking the female connector 30 inserted into the connector holding portion 11.

  On the other hand, also in the second connector holding portion 12, convex portions 12a that allow a laminated connector 40 to be described later to be inserted in an aligned state are formed on the inner wall surface of the holding portion on both sides in the connector holding portion arrangement direction. . In addition, a holder locking piece 12b (see FIG. 2) for locking the laminated connector 40 inserted into the second connector holding part 12 is formed on the inner wall surface of the second connector holding part 12.

  In addition, regarding the two connector holders 10 inserted into the male connector 50, as can be seen from FIGS. 3 and 4, a holder miscoupling prevention groove for preventing the connector holder 10 from being erroneously coupled to the male connector 50 in the left-right direction. Regarding the components other than 15, the two connector holders 10 inserted into one male connector 50 have the same shape and the same dimensions.

  Next, the structure of the lever 20 will be described. FIG. 7 is a perspective view of the lever 20, and FIG. 8 is a perspective view of the lever 20 of FIG. 7 viewed from the opposite side. The lever 20 is also made of a sufficiently strong resin material that is easy to mold at the time of manufacture and can be used for a long time. The lever 20 is formed of a substantially rectangular plate-like body having a finger-hook portion 21 at one corner, A rotating shaft hole 22 is formed near the portion, and the lever holding shaft 14 a of the connector holder 10 is engaged with the rotating shaft hole 22. Then, in a state where the lever holding shaft 14a of the connector holder 10 is engaged with the rotation shaft hole 22, this engaging portion becomes a fulcrum when the lever 20 is considered as a lever.

  In addition, a lever temporary locking groove 23 having a predetermined length in an arc shape around the rotation shaft hole is formed on one side surface of the lever 20 near the rotation shaft hole 22 so as not to penetrate the lever 20. . In addition, a first temporary locking through hole 23a having a circular hole cross section for lever temporary locking is formed at both ends of the lever temporary locking groove 23, and a second hole having an elliptical cross section is formed. A temporary locking through hole 23b is formed. The lever temporary locking pin 14b of the connector holder 10 is relatively movable in the lever temporary locking groove 23 by the rotation of the lever 20 around the lever holding shaft. Then, the lever temporary locking pin 14b relatively moves in the lever temporary locking groove 23, and the lever temporary locking pin 14b is fitted into the first temporary locking through hole 23a at one end of the lever temporary locking groove. Thus, the lever 20 is temporarily locked at the first temporary locking position, and the lever temporary locking pin 14b is fitted into the second temporary locking through hole 23b at the other end of the lever temporary locking groove. By doing so, the lever 20 is temporarily locked at the second temporary locking position.

  On the other hand, a notch is formed as a connector low fitting groove 24 in a part of the lever periphery. The connector low-fitting groove 24 meshes with a low-fitting cam protrusion 51a of a male connector 50 described later, and by rotating the lever 20, the plurality of female connectors 30 and the laminated connector 40 are moved to the male connector side together with the connector holder 10. It plays the role of mating connectors with low mating force. That is, when the lever 20 is considered as a lever, a portion where the connector low fitting groove 24 and the low fitting cam protrusion 51a mesh with each other plays a role of an action point. In addition, a finger hooking portion 21 for turning the lever 20 around the lever holding shaft by applying a force with a finger is formed on the opposite side of the lever peripheral corner portion from the connector low fitting groove 24. In addition, a plurality of protrusions 21a are formed in parallel on the finger hanging portion 21 to prevent the slipping of the fingers when the lever is rotated. When the lever 20 is considered to be a lever, the finger hook portion 21 corresponds to a power point. In addition, a flexible lever lock piece 25 (see FIG. 8) for locking the lever 20 to the male connector 50 is formed immediately below the finger hook portion 21 when the male female connector is fitted. A lever lock claw 26 is formed on a part of the piece 25.

  Next, the female connector 30 that is inserted into the connector holding portion 11 of the connector holder 10 and requires a relatively large fitting force with the male connector 50 will be described. FIG. 9 is a perspective view of the female connector 30, and FIG. 10 is a perspective view of the female connector 30 viewed from the opposite side of FIG. The female connector 30 is also made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long period of time, has a thin rectangular parallelepiped shape, and has a terminal housing portion arranged in parallel and a terminal insertion on one end face A plurality of openings 30a are formed in parallel, and a terminal insertion port (not shown in FIGS. 9 and 10) of the male connector 50 is formed on the side opposite to the terminal insertion opening 30a. As shown in FIG. 10, a flexible cantilever-shaped housing lance (terminal insertion detection piece) 31 is formed in parallel on the side of the female connector 30. A terminal (not shown) attached to () is inserted from above in FIGS. 9 and 10, and a part of the terminal is locked by the housing lance 31. When the female connector 30 is inserted into the first connector holding part 11 of the connector holder 10, the connector engaging convex part 17 formed on the connector holder 10 reaches a position where it overlaps the housing lance 31. When the terminal is correctly inserted into the female connector 30, the housing lance 31 maintains a normal bending state, and the housing lance 31 is correctly engaged with the connector engaging convex portion 17. On the other hand, when the terminal is half inserted into the female connector 30, the housing lance 31 is abnormally bent and the housing lance 31 does not engage with the connector engaging convex portion 17, whereby the terminal is completely or incompletely inserted into the female connector 30. Can be confirmed.

  Further, engaging portions 32 with the connector holder 10 are formed on both side surfaces of the female connector 30, and the engaging portions 32 and the holder locking pieces 11a (see FIG. 1) of the connector holder 10 cooperate to form a female connector. 30 is locked to the connector holder 10.

  Subsequently, the laminated connector 40 inserted into the second connector holding portion 12 of the connector holder 10 will be described with reference to FIGS. 11 to 15. 11 and 12 show the connector 42 stacked on the upper layer from the second layer, and FIGS. 13, 14 and 15 are assembled on both outermost layers of the plurality of connectors shown in FIG. 11 and FIG. It is the perspective view which showed the connectors 41 and 43. FIG. 12 and 14 are perspective views of the connectors 41 and 42 shown in FIGS. 11 and 13 as viewed from the opposite side. Each of the connectors 41 to 43 constituting the laminated connector 40 is made of a sufficiently strong resin material that is easy to be molded at the time of manufacture and can be used for a long time, has a thin rectangular parallelepiped shape, and has terminal accommodating portions arranged in parallel inside. In addition, a female connector terminal insertion opening 40a is formed on one end face, and a male connector terminal insertion opening (not shown) is formed on the opposite side of the female connector terminal insertion opening 40a. The laminated connector 40 can be multipolarized as the laminated connector 40 by laminating each connector 42 and the connectors 41 and 43 after inserting a wire harness terminal (not shown) into each connector 42 before lamination. I have to.

  Each connector has a secondary locking projection 40c (refer to FIG. 12) and a secondary locking insertion hole 40d (refer to FIG. 11), which are adjacent to each other at the stage of stacking the connectors 41 to 43. The secondary locking protrusions 40c and the secondary locking insertion holes 40d of the connectors 41 to 43 are engaged with each other. Each connector is provided with an interlayer lock 40e (see FIG. 12) and an interlayer lock engaging portion 40f (see FIG. 11), and the adjacent connectors 41-43 that overlap each other at the stage of stacking the connectors 41-43. The interlayer lock 40e and the interlayer lock engaging part 40f are engaged with each other. Note that the secondary locking projection 40c serves to confirm the presence or absence of incomplete terminal insertion and to reinforce the strength of the housing lance 31.

  In stacking each connector 41, the connector 41 shown in FIGS. 13 and 14 is the first layer, and a required number of connectors 42 shown in FIGS. 11 and 12 are stacked thereon, and finally the connector 43 shown in FIG. The laminated connector 40 is completed by assembling.

  Next, the male connector 50 will be described. FIG. 16 shows a perspective view of the male connector 50. The male connector 50 is also made of a sufficiently strong resin material that is easy to mold during manufacture and can be used for a long time, has a thin rectangular parallelepiped shape, and a connector holder insertion portion in which two connector holders 10 can be inserted in a predetermined arrangement Two 51 are formed side by side in the width direction of the male connector 50. Each connector holder insertion portion 51 is provided with a misconnection prevention wall 52 for preventing the connector left and right misconnection when the connector holder 10 is inserted into the male connector 50. As a result, if the incorrect connection prevention wall 52 and the right and left connector holders 10 do not match the different connection prevention grooves 15 formed in different shapes, the female connector 30 and the connector holder 10 in which the laminated connector 40 is inserted are aligned correctly. Therefore, it cannot be inserted into the male connector 50.

  Further, the connector holder insertion portion 51 of the male connector 50 is provided with a low fitting cam projection 51 a on one side wall thereof, and the low fitting cam projection 51 a is rotated by turning the lever 20. By engaging the connector low fitting groove 24 provided in the lever 20 and further rotating the lever 20, the meshed portion becomes a so-called lever action point, and the connectors are fitted with a low fitting force. Yes.

  A plurality of terminal insertion holes 51b into which male terminals can be inserted are formed side by side on the bottom surface of the male connector 50, and a convex wall 51c for preventing terminal twisting is formed. A lock claw engagement portion 55 is formed on the inner wall of the connector holder insertion portion 51, and a temporary locking release piece 56 is formed. Further, a fitting temporary locking groove 57 is formed in the erroneous coupling preventing wall 52.

  In the present embodiment, as described above, a structure is shown in which two connector holders 10 to which the female connector 30 and the laminated connector 40 are attached can be assembled to the male connector 50. However, it goes without saying that it is not necessary to limit the two connector holders 10 to which the female connector 30 and the laminated connector 40 are attached to the male connector 50 in this way.

  Next, a method of assembling the lever type low fitting connector 1 having such a structure and fitting the connectors together will be described. First, as shown in FIG. 17, the lever 20 is assembled to the connector holder 10. In this assembly, the lever 20 is pushed into the lever housing groove from the front opening of the lever housing groove 14 of the connector holder 10, so that a part of the lever 20 is a tapered portion 14 t for guiding the lever of the lever holding shaft 14 a (FIG. 2). See). Then, by further pushing the lever 20 into the lever receiving groove 14 of the connector holder 10, the rotation shaft hole 22 of the lever 20 is engaged with the lever holding shaft 14a and the lever temporary locking pin 14b of the connector holder 10 (FIG. 2) is engaged with the lever temporary locking groove 23 (see FIG. 7), and the lever holding shaft 14 is used as a fulcrum of the lever so that the lever temporary locking pin 14b is limited in movement by the temporary locking groove 23. The lever 20 is assembled to the connector holder 10 so as to be rotatable.

  FIG. 17 is a perspective view showing a cross-sectional shape of the connector holder 10 with the lever 20 attached thereto. FIG. 17 shows a state in which the lever 20 rotates clockwise in the drawing and the lever temporary locking pin 14b of the connector holder 10 enters the first temporary locking through hole 23a of the lever 20 and is temporarily locked. Is shown. In this first lever temporary locking state, the female connector 30 can be inserted into the connector holder 10. That is, the lever temporary locking pin 14b and the first temporary locking through hole 23a are engaged to maintain the lever 20 in the first lever temporary locking state, so that the lever 20 is connected to the female connector 30. A plurality (two in the case of this embodiment) of female connectors 30 can be inserted into the first connector holding part 11 without interference. FIG. 18 shows a state immediately before the female connector 30 is inserted into the connector holder 10 by rotating the lever 20 and temporarily locking it at the first temporary locking position. In this state, the two female connectors 30 are inserted into the first connector holding portion 11.

  Subsequently, an operation of inserting the two female connectors 30 into the connector holder 10 will be described. Prior to inserting the two female connectors 30 into the connector holder 10, the terminals of the wire harness are inserted into the female connector 30 in advance. Here, the housing lance 31 maintains a normal state when the terminals are completely inserted into the female connector 30. As a result, as shown in FIGS. 19 and 20, when all the terminals are completely inserted into the female connector 30, when the female connector 30 is inserted into the first connector holding portion 11 of the connector holder 10, the connector holder The connector engaging projection 17 as a front retainer 10 is engaged with the housing lance 31 in a normal state, and the female connector 30 can be inserted into the connector holder 10 to a predetermined position. On the other hand, if the female connector 30 has at least one terminal that is incompletely inserted, the connector engaging projection 17 formed on the connector holder 10 and the housing lance 31 of the female connector 30 interfere with each other. The first connector holding part 11 of the holder 10 cannot be completely inserted to a predetermined position. Thereby, it can be easily confirmed from the outside whether all the terminals are completely inserted into the female connector 30 or at least one terminal is incompletely inserted.

  FIG. 21 shows a state in which one female connector 30 is inserted into the first connector holding portion 11 of the connector holder 10. Further, in FIG. 22, the lever 20 is rotated clockwise as viewed in the same figure to be in the second temporarily locked state, so that the laminated connector 40 can be inserted into the second connector holding portion 12 of the connector holder 10. FIG. FIG. 23 is a perspective view showing the state of FIG. 22 in section.

  After inserting the two female connectors 30 into the connector holder 10 from the state shown in FIG. 21, the lever 20 is rotated to position the lever 20 at the second temporary locking position as shown in FIGS. . As shown in FIGS. 22 and 23, when the lever 20 is rotated counterclockwise in FIG. 17 from the first temporarily locked state of the lever 20 shown in FIG. 14 b enters the second temporary locking through hole 23 b (see FIG. 7) of the lever 20. At the same time, the lever locking claw 14c (see FIG. 1) formed on the connector holder 10 is engaged with the holder temporary locking claw receiving portion 27 (see FIG. 7) of the lever 20, so that the lever 20 is connected to the connector. The holder 10 is temporarily locked at the second locking position. In this state, the lever 20 is not positioned above the opening of the second connector holding portion 12, so that the laminated connector 40 can be easily inserted into the second connector holding portion 12.

  Next, a low fitting operation between connectors using the lever 20 will be described. When the connector holder 10 to which the female connector 30 and the laminated connector 40 are attached as described above is inserted into the male connector 50, the fitting temporary locking groove 57 (see FIG. 16) of the male connector 50 and the holder locking piece of the connector holder 10 11a and 12b (see FIG. 1) mesh with each other, and the temporary locking release piece 56 (see FIG. 16) formed inside the wall of the male connector 50 flexes the lever locking claw 14c (see FIG. 1) of the connector holder 10. Release the lever temporary lock. Accordingly, the lever 20 can be further rotated from the second temporary locking position. Thereafter, the finger-holding portion 21 is pressed against the male connector side and the lever 20 is rotated around the lever holding shaft, so that the lever holding shaft 14a is the fulcrum of the lever, the finger-holding portion 21 is the power point, and the connector low fitting groove 24 is the operating point. As a result, the lever 20 rotates. At this time, since the distance between the lever holding shaft 14a and the finger hooking portion 21 is larger than the distance between the lever holding shaft 14a and the connector low fitting groove 24, the female connector 30 having a large number of terminals and the laminated connector 40 can be used as an insulator. By this principle, the male connector 50 can be fitted at a time with a low fitting force. Then, by engaging the lever lock claw 26 (see FIG. 8) with the lock claw engaging portion 55 (see FIG. 16) of the male connector 50, all fitting operations are completed.

  In addition, what is necessary is just to rotate the lever 20 to a reverse direction, when releasing the fitting of the connectors once fitted. Accordingly, the plurality of female connectors 30 and the laminated connector 40 can be released from the male connector 50 at a low fitting force at a time based on the above-described lever principle. The state in which the male connector 50 is pulled away from the connector holder 10 after the terminals of the plurality of female connectors 30, the laminated connector 40 and the male connector 50 are released, and the lever 20 is positioned at the second temporary locking position. Then, the laminated connector 40 is removed from the connector holder 10. And after rotating the lever 20 to the 1st temporary latching position, the connector fitting cancellation | release operation | work can be easily finished by extracting all the female connectors 30 from the connector holder 10. FIG.

  As described above, in addition to the fact that the plurality of connectors 30 and 40 can be simultaneously fitted with a low fitting force by the rotation of the lever 20 attached to the connector holder 10, the lever type low according to the present invention is used. Since the fitting connector 1 can be separately attached to the connector holder 10 with a plurality of connectors 30 and 40 that are separated for each separate sub-harness, work at the time of manufacturing the harness is facilitated.

  Further, by forming the connector engaging convex portion 17 having a retainer function in the connector holder 10, the number of parts can be reduced as compared with a method in which a retainer is directly fitted like a conventional connector. . A retainer and a connector that are integrally formed with a connector so as to be integrated with the connector via a hinge have been conventionally used, but there is a drawback that a molding die becomes complicated if it is provided with a hinge. On the other hand, the lever-type low-fitting connector according to the present invention can form the retainer function part in the connector holder with a simple shape as compared with such a conventional example, and the cost is reduced without complicating the mold. To contribute.

  In addition, by providing a single-plate lever in the center of the connector holder, the connector width can be reduced compared to conventional connectors with levers that straddle both sides of the connector. Similarly, the width of the side connector can be reduced, and the overall size of the connector can be reduced.
