Abstract

PURPOSE: To ensure high operability of a lever even in the case where there is a limitation in a mounting environment by forming a pair of spread diametric parts in a protruding end of each support shaft. CONSTITUTION: In both end surfaces in the lengthwise direction of a female housing 10, a pair of support shafts 16 for supporting a lever 30 are protrusively formed by conforming an axial line. Spread diametric parts 17A, 17B are formed in a shape symmetrical relating to a line in a fitting direction of passing an axial center of the support shaft 16. In a state that the lever 30 is placed in an unfitted attitude, a cam groove 36 in an inner side surface of both leg parts 32 is engaged with a protrusion of a male housing, and from this state, when the lever 30 is turn-operated, the male housing is relatively pulled relating to the female housing 10, to fit both the housings when the lever 30 leads to a fitted attitude. When the lever 30 is turned in an unfitting direction from a fitting state, by engaging the cam groove 36 with the protrusion, the male housing is moved so as to go away from the female housing 10.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lever type connector in which housings are fitted together by levers.

[0002]

2. Description of the Related Art The structure of a lever-type connector in which male and female housings are fitted with a lever is as follows. "Ko"
A pair of bearing holes formed in both leg parts of the L-shaped lever are fitted to a pair of support shafts formed in one of the housings, and a cam groove formed in both leg parts is fitted in a protrusion formed in the other housing. When the lever is rotated in this state, both housings are easily drawn and fitted together.

Usually, when the male and female housings are fitted to each other, a fitting resistance is generated due to a frictional force due to elastic contact between the male and female terminal fittings mounted on both housings. In particular, a connector having a large number of poles has a large fitting resistance. However, in the lever-type connector, the "levering action" allows a large fitting force to be generated even with a small operating force, so that the fitting operation can be easily performed.

[0004]

In the lever type connector, the mounting posture of the lever with respect to the housing is predetermined because of the engagement between the cam groove and the protrusion. Therefore, for example, when the lever-type connector is mounted in a narrow space and the mounting posture is restricted, there is a possibility that a sufficient empty space cannot be secured around the area where the lever rotates. . In such a case, it becomes difficult to operate the lever, and workability deteriorates.

The present invention was devised in view of the above circumstances, and an object thereof is to ensure high operability of the lever even when the mounting environment is restricted.

[0006]

As means for solving the above-mentioned problems, the invention of claim 1 has a pair of housings into which terminal fittings that can be fitted to each other are inserted, and a pair of housings formed in the one housing. A support shaft and a lever in which a pair of bearing holes formed in both legs and having a U-shape are rotatably fitted to the support shaft are provided, and the lever is engaged with the other housing to rotate. In this way, in a lever-type connector in which the terminal fittings are fitted together while pulling the pair of housings closer to each other, the lever can be detached from the one housing, and the pair of support shafts and the pair of bearing holes are fitted together. It is characterized in that the lever is selectively attached to the housing in two mounting states in which the combinations are reversed.

According to a second aspect of the present invention, in the first aspect of the invention, the support shaft and the bearing hole are provided with retaining means for restricting the leg from coming off the support shaft by engaging with each other in the axial direction thereof. The retaining means provided on the support shaft side is characterized in that it has a configuration that is line-symmetric with respect to an axis parallel to the fitting direction of the terminal fitting.

According to a third aspect of the invention, in the second aspect of the invention, the enlarged diameter portion and the notch portion are symmetrical with respect to the axis of the support shaft.
The shapes of the one expanded portion and the one cutout portion, which are arranged at a position and provided one by one, and which can be aligned with each other, have the shapes of the other expanded diameter portion and the other cutout portion which are located on the opposite side to these. It has a feature in that it is configured differently.

The invention of claim 4 is claim 2 or claim 3.
In the invention of claim 1, the cutout portion is arranged at a position where it can be fitted to the expanded diameter portion when the lever is in a posture outside the range of rotation during the fitting operation of the terminal fitting. It has characteristics.

The invention of claim 5 is the invention of claims 1 to 4.
In any one of the inventions, the support shaft is characterized in that the support shaft is arranged in a position that allows the moments in both the forward and reverse directions generated around the support shaft to be balanced by the fitting resistance between the terminal fittings. .

[0011]

According to the first aspect of the present invention, either one of the two mounting methods in which the pair of support shafts and the pair of bearing holes are combined in the opposite combination depending on the mounting environment. The lever can be attached to the housing with.

According to the second aspect of the present invention, even when a force in the direction of pulling out from the support shaft acts on the leg portion of the lever at the time of fitting operation of the pair of housings, the pulling holes provided in the support shaft and the bearing hole are provided. By engaging the stopping means in the axial direction, the leg is restricted from being removed from the support shaft. Further, since the enlarged diameter portion is line-symmetric with respect to the axis line in the fitting direction, the posture of the lever at the time of mounting on the housing in two mounting methods in which the combination of the support shaft and the bearing hole is reversed is also the above. It becomes line symmetric with respect to the axis of the fitting direction.

In the invention of claim 3, the lever is attached and detached by fitting the bearing hole and the support shaft in a state in which the notch is aligned with the expanded diameter portion. Even if a force is applied to the leg portion of the lever during the fitting operation in the direction of withdrawing from the support shaft, the enlarged diameter portion engages with the outer surface of the leg portion, which may cause the leg portion to detach from the support shaft. There is no. Since the enlarged diameter portion is provided at two positions that are symmetrical with respect to the axis of the support shaft, the engagement of the enlarged diameter portion with the leg portion is stabilized and the strength is improved. Further, since the enlarged diameter portions and the cutout portions located on the opposite sides have different shapes from each other, the enlarged diameter portion that can be fitted in each of the two mounting states that the lever can have. The combination of the notch and the cutout is determined in one way. Therefore, the mounting postures of the lever in the two mounting methods are correctly line-symmetric with respect to the axis line in the fitting direction.

According to another aspect of the present invention, the enlarged diameter portion and the cutout portion do not align during the fitting operation by rotating the lever, and the enlarged diameter portion is always kept in the fitting operation. The engagement with the outer surface of the leg is maintained.

In the fifth aspect of the present invention, even when the lever is mounted by any one of the two mounting methods in which the pair of supporting shafts and the pair of bearing holes are fitted in the opposite combination, Since the support shaft is arranged so as to balance the moments in the forward and reverse directions around the support shaft caused by the fitting resistance between the terminal fittings, twisting is prevented due to the relative inclination of the housing due to the fitting resistance. It never happens.

[0016]

According to the first aspect of the present invention, the lever mounting method can be selected so that the lever can be easily operated according to the mounting environment, so that the workability of the lever operation can be improved.

According to the second aspect of the present invention, the legs are prevented from coming off the supporting shaft during the fitting operation by the retaining means provided in the supporting shaft and the bearing hole. A turning operation can be performed. Further, the retaining means on the support shaft side is line-symmetric with respect to the axis line in the fitting direction,
In any of the two mounting methods in which the pair of support shafts and the pair of bearing holes are fitted in a reverse combination, there is no problem in fitting the support shaft and the bearing holes.

According to the third aspect of the present invention, the expanded portion formed on the support shaft restricts the leg portion from being removed from the support shaft during the fitting operation. Therefore, it is stable as in the second aspect of the invention. It is possible to perform a reliable turning operation of the lever. Also,
Since the enlarged diameter portion is provided at two positions that are symmetrical with respect to the axis of the support shaft, it is possible to reliably and reliably prevent the legs from coming off the support shaft. Furthermore, by making the shapes of the expanded portions located on the opposite side different from each other, the mounting postures of the levers in the two mounting methods are made line-symmetric with respect to the axis line in the fitting direction. Also, the lever is prevented from being installed illegally.

According to the fourth aspect of the present invention, since the enlarged diameter portion and the notch portion do not align with each other during the turning operation of the lever, the leg portion can be removed from the support shaft in accordance with the fitting operation. It is possible to reliably prevent the removal of the acting force.

According to the fifth aspect of the present invention, in any of the two mounting methods in which the pair of supporting shafts and the pair of bearing holes are fitted in the opposite combination, the terminal fittings are attached to each other. Since there is no possibility that the relative postures of the housings will change due to the fitting resistance, the lever can be easily operated.

Are arranged corresponding to the center position between a pair of support shafts 16 described later, and are formed symmetrically with respect to a line in the fitting direction orthogonal to the axis of the support shaft 16. Therefore, the engagement claw 37 can be engaged with the lock claw 25 even when the harness cover 20 takes any one of two postures in which the wire outlet 21 is directed in the opposite direction.

A pair of support shafts 1 for supporting the lever 30 is provided on both end surfaces of the female housing 10 in the longitudinal direction.
Numerals 6 and 16 are formed so that their axes coincide with each other. The axis line of the support shaft 16 is the same as the male housing 10 and the female housing 10.
The support shafts 16 are arranged on both end surfaces of the female housing 10 at right angles to the fitting direction of the above, and are set as follows.

When the male terminal fitting and the female terminal fitting are fitted together, an elastic contact piece (not shown) provided inside the female terminal fitting.
Since the tabs (not shown) of the male terminal fittings are clamped by the elastic force of, the contact pressure causes a fitting resistance for each terminal fitting, and these fitting resistances cause a moment around the support shaft 16 to be male. It will occur between the housing and the female housing 10. This moment is due to the position where the tab is clamped in the female terminal fitting, the state of the arrangement of the female terminal fitting, and the strength of the clamping force of the elastic contact piece when different types of terminal fittings are used. It depends on various conditions. Therefore, in this embodiment, considering these various conditions,

Moreover, the position of the support shaft 16 is set relative to the arrangement of the terminal fittings so that the moment generated by fitting the terminal fittings arranged on one side and the moment created by fitting the terminal fittings arranged on the other side are balanced. Is set to. Since the position of the support shaft 16 is determined so that the moments are balanced in this way, when the male housing and the female housing 10 are fitted together, a moment around the support shaft 16 does not occur between the two housings, and both housings are not generated. Are fitted so as to move in parallel while facing each other. Further, in FIG. 3, the height of the axis of the support shaft 16 is approximately the same as the thickness from the uppermost cavity 11 to the upper surface of the female housing 10 and the thickness from the lowermost cavity 10 to the lower end surface of the female housing 10. The position is slightly higher than the center of the height of the female housing 10 that does not include the protrusion 15 in the case of. In view of this, in the present embodiment, the fact that the axis of the support shaft 16 and the center of the height of the female housing 10 are misaligned is used to provide the protrusion 15 for preventing reverse fitting with the male housing, on the upper surface of the female housing 10. It is provided on the side and is set so that the center of the height of the female housing 10 including the protruding portion 15 and the height of the axis of the support shaft 16 coincide with each other.

A pair of enlarged diameter portions (removal preventing means which is a constituent feature of claim 1) is provided on each of the projecting ends of the respective support shafts 16.
17A and 17B are formed. This pair of expanded parts 1
7A and 17B are expanded in the diametrically opposite directions with an angular interval of 180 ° from each other, and the expanded direction is the fitting direction of both housings. The expanded diameter portions 17A and 17B are line-symmetrical with respect to a line in the fitting direction passing through the axis of the support shaft 16. Further, the pair of expanded diameter portions 17A and 17B have different shapes. That is, the convex portion 18A is formed on the outer peripheral edge of the one enlarged diameter portion 17A.
On the other hand, a concave portion 18B is formed on the outer peripheral edge of the other expanded diameter portion 17B. Such expanded diameter portion 1
7A and 17B engage with the outer surface of the leg portion 32 of the lever 30 and thus function to prevent the lever 30 from coming off the support shaft 16.

The lever 30 has a pair of plate-shaped legs 32, 32 connected to both ends of an operating portion 31 extending in the longitudinal direction of the female housing 10, and has a "U" shape as a whole. A pair of bearing holes 33, 33 penetrating the both legs 32, 32 so as to open on both inner and outer surfaces thereof are formed with their axes aligned. The bearing hole 33 is fitted into the support shaft 16 so as to be relatively rotatable, and thus the lever 30 is supported by the female housing 10.

The lever 30 has a fitting release posture (see FIG. 5) in which the operating portion 31 is located on the front side of the female housing 10, and the operating portion 31 is tilted at an angle of approximately 90 ° from the fitting release posture. It can be rotated between a fitting posture (see FIG. 6) positioned on the electric wire extension surface 12 side. With the lever 30 in the fitting release posture,

This posture is a state in which the lever 30 is rotated by an angle of approximately 135 ° in the fitting releasing direction from the fitting posture shown in FIG. 5, that is, the fitting posture which is a range in which the lever 30 is rotated when the fitting operation of both housings is performed. It is in a state of being rotated more than 90 degrees from the rotation range.

Therefore, the lever 30 is placed in the posture shown in FIG.
By rotating the notches 34A, 34B and the expanded diameter portions 17A, 17
By fitting the lever 30 to the support shaft 16
It can be attached to and detached from. Then, after the lever 30 is once mounted, as long as the lever 30 is normally rotated, the expanded diameter portions 17A and 17B and the cutout portion 3 are formed.
4A and 34B do not match.

Further, the expanded diameter portions 17A, 17B of the support shaft 16
Is axisymmetrical with respect to the axis of the fitting direction, the two supporting shafts 16, 16 and the two bearing holes 33, 33 are fitted in two different postures (see FIG. 5). The lever 30 can be mounted in the posture shown and the posture shown in FIG. 11. Moreover, in these two mounting postures,
The lever 30 draws a rotation locus that is line-symmetric with respect to the axis of the fitting direction. In addition, the two expanded diameter portions 17 forming a pair
Since the shapes of A and 17B are different from each other, it is regulated that the operating portion 31 of the lever 30 is mounted in an incorrect posture such that it is located on the right side of the female housing 10 in FIG.

Further, on the outer surface of the leg portion 32, there is formed a housing recess 39 which is concentric with the bearing hole 33.
The notches 34A and 34B are formed in the accommodation recess 39. The accommodating recess 39 is formed by the expanded diameter portions 17A, 17
In the state in which the bearing hole 33 is fitted in the support shaft 16, the expanded diameter portions 17A, 17 are recessed by the same dimension as the thickness of B.
B does not project beyond the outer surface of the leg portion 32.

Next, the operation of this embodiment will be described.
When the lever 30 is attached to the female housing 10, the harness cover 20 is removed from the female housing 10. With the lever 30 in the posture shown in FIG.
When the expanded diameter portions 17A and 17B and the cutout portions 34A and 34B are aligned as shown in FIG. 10 in a state in which 2 is elastically spread outward slightly, the lever 30 can be attached to the support shafts 16 and 16. . After that, the lever 30 is rotated until it takes the fitting releasing posture shown in FIG.
0 is mounted on the female housing 10. As described above, the assembling of the lever 30 and the harness cover 20 to the female housing 10 is completed.

From this state, the lever 30 is rotated to engage the male housing with the female housing 10. Then, when the lever 30 reaches the fitting posture, the locking claw 25 and the engaging claw 37 are engaged with each other to lock the lever 30, whereby the male housing and the female housing 10 are locked in the fitted state.

In this fitting operation, the lever 3 is placed at a position where the moments that accompany the fitting operation are balanced.
Since 0 is arranged, twisting does not occur between the male housing and the female housing 10, and a smooth fitting operation can be performed.

Further, as the fitting is applied, a pressing force is applied to the leg portion 32 in the direction of expanding the leg portion 32.
Since A and 17B are engaged with the outer surfaces of the leg portions 32 and 32, the leg portion 32 is prevented from being displaced with respect to the support shaft 16 so as to be pulled out to the outside. Moreover, the expanded portion 1
Since 7A and 17B are arranged at two positions at an angle of 180 ° around the axis of the support shaft 16, the retaining function of the leg portion 32 is stably exerted with high strength.

When the two housings are disengaged from each other, when the elastic bending portion 23 of the harness cover 20 is elastically deformed by being pinched with fingers, the holding projection 24 is disengaged from the locking portion 14 and the harness cover 20 is locked. The harness cover 20 is slid to the unlocked position as it is. Then, the lock claw 25 is disengaged from the engagement claw 37 and the lock of the lever 30 is released.

After that, the male housing and the female housing 10 are relatively separated by operating the lever 30 in the fitting releasing direction. Also during this fitting release operation, as in the fitting operation, the moments around the support shaft 16 due to the frictional resistance between the male terminal fitting and the female terminal fitting are balanced, so that between the male housing and the female housing 10. There is no twisting. Therefore, the fitting release operation can be smoothly performed.

When changing the mounting posture of the lever 30, first, the harness cover 20 is removed from the female housing 10, and then the lever 30 is removed. At this time, the lever 30 is rotated to the posture shown in FIG.
34B is aligned with the expanded diameter portions 17A and 17B, and from this state, the bearing holes 33 are removed from the support shaft 16 by elastically deforming the both leg portions 32 and 32 to the outside. The lever 30 thus removed is turned to the posture shown in FIG. 11, and the lever 30 is mounted by the same procedure as described above. Then, the harness cover 20 may be attached after the lever 30 is attached.

As described above, according to the lever type connector of this embodiment, the lever 30 can be mounted on the female housing 10 in two different postures. Therefore, the mounting method of the lever 30 can be selected according to the mounting environment. By doing so, for example, even when the lever-type connector is mounted in a narrow space, the lever 30 can be easily operated.

Moreover, the position of the support shaft 16 is determined in consideration of the moment around the support shaft 16 caused by the fitting resistance caused by the fitting operation of the two housings, so that the lever 30 has one of two positions. In any of the above postures, no twisting occurs between the housings, and the lever 30 can be operated smoothly.

Further, in this embodiment, the position of the axis of the support shaft 16 set so as to balance the moment due to the fitting resistance is such that the height of the female housing 10 including the protrusion 15 for preventing reverse insertion with the male housing. Since it coincides with the center of the height, the operating portion 31 of the lever 30 is attached to the female housing 1 even when the lever 30 is attached in either of two postures.
It is designed so that no unnecessary gap is created between 0 and 0. Therefore, the overall size of the female housing is reduced.
