Abstract

PROBLEM TO BE SOLVED: To reduce operation force required for fitting a connector.SOLUTION: A lock arm 20 is provided at a female connector housing 6 so as to be bent. The lock arm 20 is bent and displaced in a process of fitting female and male connector, and returned with the completion of the fitting to lock to a male connector housing 1. The lock arm 20 is integrally provided with a pressing member 8. The pressing member 8 is assembled in a storage hole 17 of the female connector housing 6 so as to be displaced, and displaced in the storage hole 17 together with the lock arm 20 when the lock arm 20 is bent at the time of fitting. Therefore, the pressing member 8 pushes down a rear end of a tongue piece 15 of a female terminal fitting 9, so that friction force at fitting is reduced. Consequently, fitting operation force can be reduced.

Description

  The present invention relates to a connector.

  2. Description of the Related Art Conventionally, a technique is known in which frictional resistance when fitting male and female connector housings is reduced, and a fitting operation force is kept as low as possible. As an example, the following Patent Document 1 can be cited.

  This is provided with a pressing member capable of pressing down the tongue of the female terminal fitting on the female connector housing. The pressing member is held at two positions, a position where the pressing member is inserted shallowly and a position where the pressing member is inserted deeply. In the shallow insertion position, the pressing member waits at a position where the female terminal fitting can be inserted into and removed from the cavity, and in the deep insertion position, the tongue pieces of each female terminal fitting are pushed down at the same time, and the tongue pieces are male terminals. It is held at a position where it can be held at a height that does not contact the tab portion of the metal fitting.

  When the male and female connector housings are fitted, the pressing member is held at a position where it is deeply inserted into the connector housing, and the tongue piece is held in a depressed state in advance. By doing so, when the male and female connector housings are fitted to each other, the tab portion of the male terminal fitting can be made to enter the female terminal fitting in a substantially non-contact state with the tongue piece. The pressing member is forcibly pushed up by the tapered guide surface formed on the bottom surface of the male connector housing immediately before the fitting between the connector housings is completed. In a state where both the connector housings are properly fitted, the pressing member is forcibly pushed up by a tapered guide surface formed on the male connector housing side to release the tongue piece. By carrying out like this, a tongue piece and a tab part can contact with predetermined contact pressure.

JP 2002-280133 A

  In the above-described conventional device, since the pressing member is inserted into the deep insertion position until the male and female connector housings are fitted, the tongue piece is pushed down and held in a bent state during that time. For this reason, especially when exposed to an environment under high temperature, the tongue piece is plastically deformed by creep, and there is a concern that a predetermined contact pressure cannot be obtained with respect to the tab portion.

  The present invention has been completed on the basis of the above-described circumstances, and it is possible to reduce the fitting force of the connector, and at the same time, a connector that can ensure a reliable conduction state between the male and female terminal fittings after fitting. The purpose is to provide.

  As a means for achieving the above object, the invention of claim 1 includes a female terminal fitting having a deflectable tongue piece elastically contacting the tab portion of the male terminal fitting, and a cavity capable of accommodating the female terminal fitting. A female connector housing having a female connector housing and a male connector housing which is engaged with the male connector housing by being bent and deformed in the process of mating with the male connector housing. And a lock arm that is assembled to the female connector housing and is held in a standby position in which the tongue piece is in a natural state when the lock arm is in a natural state. By displacing in conjunction with the bending operation of the arm, the tongue piece is pushed and the tongue piece is separated from the tab portion. When the male and female connector housings are completely engaged, the lever is returned to the standby position in conjunction with the return operation of the lock arm, thereby pressing the tongue piece. It is characterized in that it is configured to include a pressing member that releases the tongue piece in contact with the tab portion.

  According to a second aspect of the present invention, the female connector housing is formed with a plurality of cavities, and the connector housing communicates with each of the cavities and accommodates the pressing member. And the pressing member is provided integrally with the lock arm, and the pressing member is formed in a frame shape in which a plurality of terminal insertion holes corresponding to the cavities are opened. When in the position, the terminal insertion hole allows the female terminal fitting to be inserted into and removed from the cavity, and when in the operating position, presses the tongue piece with a pressing piece formed at the edge of the terminal insertion hole. Thus, the tongue piece is forcibly displaced.

  The invention according to claim 3 is the one according to claim 2, wherein the pressing member is formed by mixing the terminal insertion hole having the pressing piece and the terminal insertion hole not having the pressing piece. It has a characteristic where it exists.

<Invention of Claim 1>
According to the first aspect of the present invention, in the course of fitting the male and female connector housings, the pressing member pushes down the tongue of the female terminal fitting in conjunction with the bending operation of the lock arm to reach the operating position. In this operating position, the pressing member forcibly displaces the tongue piece in the direction away from the tab portion, so that the contact resistance between the terminal fittings can be reduced. When the fitting of the connector is completed, the pressing member is also returned and displaced to the standby position with the return operation of the lock arm. Since the pressing member releases the tongue piece at the standby position, the tongue piece can be brought into contact with the tab portion with a predetermined contact pressure to ensure a good conduction state.

  Further, in the first aspect of the present invention, since the pressing member is in the standby position and releases the tongue piece before the female connector housing is fitted, the tongue piece is plastically deformed by thermal creep as in the prior art. Can be avoided.

<Invention of Claim 2>

<Embodiment 1>
1 to 5 show Embodiment 1 of the present invention. First, the male connector M will be described with reference to FIG. 3. The male connector M has a male connector housing 1 made of synthetic resin. The front portion of the male connector housing 1 is a hood portion 2 that opens forward, and the rear portion is a terminal accommodating portion 31 that accommodates a plurality of male terminal fittings 3. A plurality of terminal accommodating chambers 32 are formed in the terminal accommodating portion 31, and the male terminal fitting 3 is accommodated in each terminal accommodating chamber 32, and is prevented from being detached by the lance 4. A tab portion 5 that protrudes into the hood portion 2 is integrally formed at the distal end portion of the male terminal fitting 3. The hood portion 2 is formed in a cylindrical shape into which the female connector housing 6 can be fitted, and a latch receiving portion 7 for locking the female connector F in the fitted state is formed in a recessed manner on the inner ceiling surface.

The female connector F according to the present embodiment includes a female connector housing 6 and a pressing member 8 that are integrally formed of a synthetic resin material (see FIG. 1).
The female connector housing 6 is provided with a plurality of cavities 10 for accommodating female terminal fittings 9 (see FIG. 2). In the present embodiment, each cavity 10 has two upper and lower stages, and is arranged in parallel in the width direction for each stage. Each cavity 10 penetrates in the front-rear direction (fitting / removing direction of the male and female connectors F, M), and the female terminal fitting 9 can be inserted from the rear. As shown in FIG. 3 and the like, a front stop wall 11 is formed on the front end face of the cavity 10, and the front end face of the female terminal fitting 9 is pressed against the front end face of the cavity 10 to define the advance position of the female terminal fitting 9. Tab insertion holes 12 into which the tab portions 5 of the male terminal fitting 3 enter are respectively opened in the front stop wall 11. A lance 13 for preventing the female terminal fitting 9 from coming off is provided on the bottom surface of each cavity 10 near the front end. The lance 13 can be bent in the vertical direction in the figure, and when the female terminal fitting 9 is inserted to a normal position with respect to the cavity 10, a lance hole formed in an opening on the opposite surface of the female terminal fitting 9. 14 can be locked.

  Here, the female terminal fitting 9 will be described (see FIGS. 2 and 3). The female terminal fitting 9 includes a rectangular tube portion 9A into which the tab portion 5 of the male terminal fitting 3 is inserted, and a barrel portion 9B continuous to the rear portion. It is made up of. The barrel portion 9B is composed of a wire barrel 9B-1 disposed on the front side and an insulation barrel 9B-2 disposed on the rear side, and is caulked to the wire core wire and the wire covering, respectively.

  The rectangular tube portion 9A is open at the front end surface to allow the tab portion 5 to enter, and a tongue piece 15 that elastically contacts the tab portion 5 is provided inside. The tongue piece 15 is folded back from the front end edge of the bottom surface of the rectangular tube portion 9A toward the inside of the rectangular tube portion 9A, and the middle portion in the length direction becomes the apex (which constitutes a contact portion with respect to the tab portion 5). It is formed in a mountain shape. When the tongue piece 15 is in a natural state, the distance between the apex of the tongue piece 15 and the ceiling surface of the rectangular tube portion 9A is set to be narrower than the thickness dimension of the tab portion 5, and the tab portion 5 When entering during this time, a predetermined contact pressure is obtained between them. In the tongue piece 15, the latter half side (back side) from the above-mentioned apex is gradually formed in a downward slope, but the portion protruding backward from the rear end of the square tube portion 9A rises with a steep slope, It extends to the height position slightly projecting upward and rearward from the rear edge of the upper surface, and its apex becomes a pressed edge 16 and receives a pressing force by a pressing member 8 described later. The rear side of the pressed edge 16 is bent with a downward gradient.

  As shown in FIG. 1, an accommodation hole 17 for accommodating the pressing member 8 is opened on the upper surface of the female connector housing 6. The accommodation hole 17 is provided in the middle part of the female connector housing 6 in the front-rear direction. More specifically, as shown in FIG. 3, the receiving hole 17 receives the pressed edge 16 of the tongue piece 15 when the female terminal fitting 9 is inserted at a normal depth with respect to each cavity 10. 17 is opened at a position where it can be exposed to the inside. The accommodation hole 17 is formed over the entire width range from the upper surface to both side surfaces along the width direction of the female connector housing 6. Further, the depth reaches the lower cavity 10 and is set to such a depth as to communicate with all the cavities 10.

  A mounting groove 18 for mounting the pressing member 8 is formed at the front end of the upper surface of the female connector housing 6. The mounting groove 18 is formed over the entire length of one half of the entire width of the female connector housing 6, one end (starting end) is opened on one side surface of the female connector housing 6, and the other end (terminal end) is the female connector. The housing 6 is located approximately in the center in the width direction. As shown in FIG. 3 and the like, the mounting groove 18 is formed to have a cross-sectional shape of a dovetail groove. In addition, a pair of retaining projections 19 project from the front and rear faces of the mounting groove 18 near the end portion of the mounting groove 18.

  Next, the pressing member 8 will be described (see FIGS. 1 and 2). A lock arm 20 is formed integrally with the pressing member 8. A leg portion 21 is formed at the front end of the lock arm 20, and a joint portion 22 is formed at the lower end thereof. The joint portion 22 has a cross-sectional shape that matches the cross-sectional shape (the groove shape) of the mounting groove 18, can be fitted into the mounting groove 18 from a side opening, and further moves along the mounting groove 18 Is possible. By bringing the joint portion 22 to the end of the mounting groove 18, the side surface of the joint portion 22 is locked to the both-out-preventing protrusions 19 to prevent the lock arm 20 from coming back, and the upper portion is pulled out upward. Are regulated.

  As shown in FIG. 1, the arm portion 23 extends straight rearward from the upper end of the leg portion 21 of the lock arm 20, and a lock projection 27 projects in the middle thereof. The rear end portion of the arm portion 23 is bent upward at a substantially right angle to form a standing portion 24, and the upper end portion of the standing portion 24 is further bent at a substantially right angle to the rear, so that the release operation portion 25 has a stepped shape. Is formed. Further, a connecting portion 26 for connecting to the pressing member 8 projects downward at a position near the rear end portion on the lower surface of the arm portion 23. The connecting portion 26 is formed to have a thickness in the front-rear direction that is thinner than the thickness of the arm portion 23 and has a reduced rigidity. As a result, as shown in FIG. 4, the bending of the connecting portion 26 and the pressing member 8 as a whole with respect to the arm portion 23 is permitted.

  The lock arm 20 formed in this way can be bent and deformed in the vertical direction (height direction) with the leg portion 21 as the center while being mounted in the mounting groove 18. That is, the lock arm 20 bends and deforms in the process in which the male and female connector housings 1 and 6 are fitted together (the state shown in FIG. 4). Then, the locking projection 27 is locked to the locking receiving portion 7 of the male connector housing 1 to lock the two connector housings 1 and 6 in the fitted state.

  As shown in FIG. 1, the pressing member 8 is formed in a state where it is integrally connected to the connecting portion 26 of the lock arm 20 at the center of the upper surface thereof. The pressing member 8 can be accommodated from the side with respect to the accommodation hole 17 and is formed to have substantially the same size as the entire width in the left-right direction of the female connector housing 6, but with a front-rear width slightly narrower than the front-rear width of the accommodation hole 17. It is formed and it is permitted to displace the inside of the accommodation hole 17 along the height direction. The pressing member 8 is formed in a frame shape in which a plurality of terminal insertion holes 28 are provided in parallel.

  When the lock arm 20 is attached to the female connector housing 6 and is in a natural state without bending, the pressing member 8 is held in the standby position (position shown in FIGS. 2 and 3) in the accommodation hole 17. When the pressing member 8 is in the standby position, each terminal insertion hole 28 corresponds to each upper cavity 10 in the female connector housing 6 and is coaxially aligned with the corresponding cavity 10. Therefore, when the pressing member 8 is in the standby position, the female terminal fitting 9 can be inserted into and removed from each terminal insertion hole 28.

  As shown in FIG. 3, of the four pieces constituting each terminal insertion hole 28 of the pressing member 8, both pieces facing each other in the height direction form the pressed edge 16 of the tongue piece 15 of the female terminal fitting 9 arranged vertically. A pressing piece 29 is provided for pressing down. When the pressing member 8 is in the standby position, the lower surfaces of the two pressing pieces 29 in each terminal insertion hole 28 are substantially flush with the ceiling surfaces of the upper and lower cavities 10, and both are pressed edges 16. It is held at a height position spaced above and is not in contact with the pressed edge 16.

  Further, when the pressing member 8 moves downward in the receiving hole 17 in conjunction with the bending operation of the lock arm 20 during the fitting of the male and female connector housings 1 and 6 (the position of the pressing member 8 at this time is the operating position). At the position shown in FIG. 4, the pressing pieces 29 of the terminal insertion holes 28 protrude into the corresponding upper and lower cavities 10 so as to push down the corresponding pressed edges 16 by a predetermined height. It has become. The amount of depression at this time is set so that the distance between the apex of the tongue piece 15 and the ceiling surface of the rectangular tube portion 9A is expanded to a dimension that is substantially equal to or slightly larger than the thickness dimension of the tab portion 5. is there.

  As shown in FIG. 3 and the like, the upper surface of the female connector housing 6 is provided with a locking member 30 that restricts the lock arm 20 from being inadvertently pressed after the male and female connector housings 1 and 6 are fitted. It has been. Although not shown in detail, the locking member 30 is normally held by the first holding means outside the bending space below the lock arm 20. After the connector housings 1 and 6 are fitted together, the first holding means is released, and the locking member 30 enters the bending space of the lock arm 20 at a position where the bending of the lock arm 20 can be regulated. It is held by the second holding means. However, the front portion of the locking member 30 is bifurcated by the escape groove 33, and interference with the connecting portion 26 can be avoided when entering the bending space of the lock arm 20.

  Next, the effect of Embodiment 1 comprised as mentioned above is demonstrated concretely. In a state where the lock arm 20 and the pressing member 8 are attached to the female connector housing 6, the female connector housing 6 is opposed to the male connector housing 1 (see FIG. 3). At this time, the pressing member 8 is in the standby position, and the pressing piece 29 and the pressed edge 16 are not in contact with each other.

  In the process of fitting the male and female connector housings 1, 6, as shown in FIG. 4, the lock projection 27 of the lock arm 20 abuts against the opening edge of the hood portion 2 and is bent downward and deformed. In conjunction with the bending deformation of the lock arm 20 at this time, the pressing member 8 moves downward in the accommodation hole 17 while bending the connecting portion 26. That is, the pressing member 8 is displaced from the standby position to the operating position, and in the course of the displacement, the pressing pieces 29 of the terminal insertion holes 28 push down the pressed edges 16 of the female terminal fittings 9 that are adjacent vertically. Thereby, the tongue piece 15 is forcibly held in a bent state in which the space between the apex (contact portion) and the ceiling surface of the rectangular tube portion 9A is widened. Therefore, after that, even when the fitting of the male and female connector housings proceeds and the tab portion 5 enters deeply into the rectangular tube portion 9A, the tab portion 5 passes through the apex without contacting the apex of the tongue piece 15. Since such a situation is simultaneously established in all the female terminal fittings 9, the male and female connector housings 1 and 6 can be fitted with a low operating force.

  Then, as shown in FIG. 5, when the male and female connector housings are properly fitted, the lock arm 20 is restored, and the lock projection 27 is engaged with the engagement receiving portion 7 of the hood portion 2. Thereby, both connector housings are locked in the fitted state. In conjunction with the return operation of the lock arm 20, the pressing member 8 also returns from the operating position to the standby position. As a result, the pressing piece 29 is separated from the corresponding pressed edge 16, so that the tongue piece 15 is released from the forcedly pressed state by the pressing member 8, and the tab portion 5 receives the elastic reaction force from the tongue piece 15. It is sandwiched between the ceiling surface of the rectangular tube portion 9A. As a result, since the tongue piece 15 can contact the tab portion 5 with an intended contact pressure, a stable conduction state can be ensured.

  When the fitting of the male and female connector housings 1 and 6 is completed, the first holding means (not shown) is released, and the locking member 30 enters the bending space of the lock arm 20 and is locked by the second holding means. The member 30 is held at the same position. By doing so, the bending deformation of the lock arm 20 is restricted, so that it is possible to avoid a situation where the pressing member 8 is inadvertently displaced. Therefore, even if a pressing force acts on the lock arm 20 inadvertently when the male and female connector housings 1 and 6 are fitted, the tongue piece 15 will not be displaced. They can be maintained in a good conductive state.

  When the male and female connector housings 1 and 6 are separated, after the locking by the second holding means is released and the locking member 30 is retracted out of the bending space of the lock arm 20, the lock arm 20 is bent. When operated, the lock projection 27 and the lock receiving portion 7 are unlocked, so that the male and female connector housings 1 and 6 can be separated. Even in this separation operation, the pressing force of the pressing member 8 can reduce the contact resistance of the tongue piece 15 with the tab portion 5, so that the separation operation can be easily performed.

  As described above, according to the first embodiment, when the two connector housings 1 and 6 are fitted, the tongue piece 15 is forcibly bent and deformed by using the bending operation of the lock arm 20, so that the male and female terminal fittings 3 are formed. , 9 is reduced, the operating force required for fitting the male and female connector housings 1, 6 can be reliably reduced. However, when the fitting of both the connector housings 1 and 6 is completed, the lock arm 20 is restored and the tongue piece 15 is also restored from the bent state, so that the desired contact pressure can be obtained with respect to the tab portion 5. Can do.

  In addition, in the present embodiment, since the tongue piece 15 is pushed down in conjunction with the lock arm 20, the tongue piece 15 remains in a natural state when the female connector housing 6 is a single unit. Therefore, since the tongue piece 15 is not plastically deformed before the male and female connector housings 1 and 6 are fitted, it is possible to ensure a stable contact pressure.

  Further, in the fitted state of the male and female connector housings 1, 6, since the inadvertent bending operation of the lock arm 20 is restricted by the locking member 30, the pressing member 8 is not inadvertently pushed down, An effect that a stable conduction state can be secured is also obtained. Note that one of the conditions that allow the locking member 30 to move from the position shown in FIG. 3 to the position shown in FIG. 5 is that the male and female connector housings 1 and 6 are completely fitted and the lock arm 20 is restored. Therefore, from this, the locking member 30 also plays a role of detecting fitting of the male and female connector housings 1 and 6.

<Embodiment 2>
FIG. 6 shows Embodiment 2 of the present invention. The pressing member 8 according to the first embodiment enables low friction with respect to all the female terminal fittings 9 housed in the female connector housing 6, but the pressing member 40 according to the second embodiment has low friction. The function of is partially omitted. For example, some cavities 10 in the female connector housing 6 become empty cavities 10 without insertion of the female terminal fittings 9, or some cavities 20 have female terminal fittings 9 that do not have the pressed edge 16. May be housed. As described above, for the cavities (non-target cavities: not shown) where it is not necessary to reduce the friction or to reduce the friction, the pressing pieces 29 are provided in the terminal insertion holes 41 and 42. There is no. Therefore, in the second embodiment, the terminal insertion hole 42 corresponding to the non-target cavity is not formed with a pressing piece.

  The pressing member 40 shown in FIG. 6 is attached to a female connector housing (not shown) in which cavities 10 are arranged in four upper and lower stages. In this case, in the female connector housing, the non-target cavities are the cavities 10 arranged in the second stage from the top. In the pressing member 40 of the present embodiment intended for such a female connector housing, the partition between the uppermost cavity and the second cavity from the top in the female connector housing when in the standby position The pressing piece corresponding to the wall is removed. That is, since the terminal insertion holes 42 corresponding to the cavities located in the uppermost stage on the female connector housing side and the cavities located in the second stage from the top when in the standby position, the partition by the pressing piece is eliminated. The terminal insertion hole 41 corresponding to each cavity located in the third step from the top has a half height as in the first embodiment.

  In addition, the pressing piece 43 of the illustrated pressing member 40 is located above and below the upper edge of the long hole-shaped terminal insertion hole 42 and the terminal insertion hole 41 in a normal form (half height dimension of the terminal insertion hole 42 described above). Formed on both edges.

Thus, the pressing member 40 of the present embodiment has a configuration in which the terminal insertion hole 41 that achieves low friction and the terminal insertion hole 42 that does not achieve a part are mixed. Therefore, the application range can be widened by appropriately arranging these two types of terminal insertion holes based on the requirements on the connector side.
Other configurations are the same as those of the first embodiment, and the same operational effects can be exhibited.
