Abstract

PROBLEM TO BE SOLVED: To securely hold a sheet type conductive way by preventing it from removing. SOLUTION: In this connector for a sheet type conductive way, as a sheet type conductive way 10 is inserted into a housing 2 in the condition where a holding member 30 is put in a release position, a hooking part 15 of the sheet type conductive way 10 is locked to a receiving part 29 of the housing 20. As the holding member 30 is displaced from that condition to a holding position, the sheet type conductive way 10 gets in contact with a terminal metal 25, and a presser part 35 of the holding part 30 holds the hooking part 15 in a locked condition with the receiving part 29. By hooking the hooking part 15 with the receiving part 29, removal of the sheet type conductive way 10 from the housing 20 can be securely prevented.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet-like conductive path connector.

[0002]

2. Description of the Related Art Conventionally, there is a connector disclosed in Japanese Utility Model Laid-Open No. 6-5163 as a sheet-like conductive path connector.
This is a housing in which a terminal portion of a sheet-shaped conductive path formed by arranging a plurality of conductive paths in parallel, a plurality of terminal fittings provided in the housing and connected to each conductive path of the sheet-shaped conductive path, A holding member that is displaceably mounted to the housing between a release position and a holding position. The sheet-like conductive path is inserted into the housing with the holding member at the release position, and then, when the holding member is displaced to the holding position, the sheet-like conductive path is sandwiched between the holding member and the terminal fitting to form a sheet-like conductive path. The conductive path contacts the terminal fitting, and the sheet-shaped conductive path is restricted by the elasticity of the terminal fitting.

[0003]

In the above-mentioned conventional connector, as means for holding the sheet-like conductive path in the housing, the sheet-like conductive path is restricted by the frictional resistance caused by the elasticity of the terminal fitting. The frictional resistance, that is, the holding force, increases as the contact area between the terminal fitting and the sheet-like conductive path increases. Therefore, a connector having a small number of poles has a small contact area and cannot obtain a sufficient frictional resistance, so that there is a problem that the sheet-shaped conductive path is easily detached from the housing.

The present invention has been made in view of the above circumstances, and has as its object to reliably hold and retain a sheet-like conductive path.

[0005]

According to a first aspect of the present invention, there is provided a sheet-like conductive path in which a plurality of conductive paths are arranged in parallel, a housing into which a terminal portion of the sheet-like conductive path is inserted, and a housing in the housing. A plurality of terminal fittings provided to enable connection with the sheet-shaped conductive path, and a holding member assembled to the housing so as to be displaceable between a release position and a holding position, The sheet-like conductive path is inserted into the housing with the holding member at the release position, and the sheet-like conductive path is pressed into contact with the terminal fitting by displacing the holding member to the holding position after the insertion. The sheet-like conductive path connector as described above, wherein a hook portion is provided on a side edge of the sheet-like conductive path,
The housing is provided with a receiving portion that locks with the hook portion of the inserted sheet-shaped conductive path to restrict play in the sheet-shaped conductive path in the removal direction.

According to a second aspect of the present invention, in the first aspect of the present invention, the receiving portion is disposed on the near side of the terminal fitting in the insertion direction of the sheet-like conductive path, and the holding member is located at the release position. In addition, when the sheet-like conductive path is inserted into the housing, the hook portion is locked by the receiving portion, and the sheet-like conductive path is moved by the hook as the holding member is displaced to the holding position. It is configured such that the holding member presses the terminal fitting while tilting with a locking point between the portion and the receiving portion substantially as a fulcrum.

[0007] The third aspect of the present invention is the first or second aspect.
In the present invention, when the holding member is at the release position, a locking portion between the receiving portion and the hook portion is exposed so as to be visible. According to a fourth aspect of the present invention, in the invention according to any one of the first to third aspects, the holding member is in a state in which the hook portion is locked to the receiving portion in a state where the holding member is at the holding position. Is formed with a holding portion that can be held.

[0008]

According to the first aspect of the present invention, the sheet-like conductive path can be reliably prevented from falling out of the housing by the catch between the hook of the sheet-like conductive path and the receiving part of the housing. [Invention of claim 2] When the holding member is displaced from the release position to the holding position, the hook portion of the sheet-like conductive path and the receiving portion of the housing are kept locked, so that the displacement of the holding member is maintained. The operation does not hinder the retaining state of the sheet-like conductive path.

[0010] The locking portion between the hook portion and the receiving portion can be visually checked, so that it can be confirmed whether or not the locking portion is securely locked. [Invention of claim 4] Since the hooking portion is kept in the locked state with the receiving portion by the holding portion of the holding member, the function of preventing the sheet-like conductive path from coming off is more reliable.

It protrudes on one routing route. The elastic contact piece 26 contacts the conductive path 12 of the sheet-shaped conductive path 10 at an arc-shaped contact portion 28 at the extension end. In addition, in the press contact portion 27,
When the terminal portion of the cable 21 is assembled while being pressed against the back surface of the housing 20 by the cable holder 22, the terminal portion of the cable 21 is pressed, the resin sheet is cut out, and the round conductor is in contact with the terminal fitting 25.

On the front surface of the housing 20, a pair of receiving portions 29 are formed on the right and left sides of the housing recess 24 so as to protrude toward the front side. The receiving portion 29 has a base portion 29A protruding in the insertion direction of the sheet-shaped conductive path 10.
And a receiving projection 29B projecting upward from the projecting end of the base 29A. When the sheet-like conductive path 10 is properly inserted into the housing 20, the hook 15 is locked to the receiving projection 29B from the rear (the direction opposite to the insertion direction of the sheet-like conductive path 10). ing. Further, since the receiving portion 29 protrudes outside from the front of the housing 20, when the holding member 30 is at the release position, the receiving portion 29 is exposed so as to be visible from above. The receiving portion 29 is provided with the elastic contact piece 2.
6 is located behind the contact portion 28 in the insertion direction of the sheet-like conductive path 10.

The holding member 30 has a fitting plate portion 31 formed in a horizontal plate shape along the width direction of the accommodating concave portion 24 and capable of being fitted into the accommodating concave portion 24. It comprises a pair of coupled support portions 32 and a pair of locking pieces 33 extending cantilevered from the support portion 32 to the housing 20 side. The locking piece 33 is connected to the housing 2.

Are held at a standby position (see FIGS. 1 to 3) and a holding position (see FIG. 4). In addition, between the standby position and the holding position, the holding member 30 slides along the substantially same direction as the direction in which the sheet-like conductive path 10 is inserted into the housing 20.

When the holding member 30 is assembled to the housing 20, the height of the upper surface of the fitting plate portion 31 is lower than the lower end of the contact portion 28 of the terminal fitting 25 in the free state, and the height difference is a sheet-shaped conductive member. Road 10 terminal (reinforcement 1
4 (including No. 4). The height of the upper surface of the fitting plate portion 31 is higher than the upper surface of the base 29A of the receiving portion 29 of the housing 20 and lower than the upper end of the receiving protrusion 29B. Is set to be the same as or slightly larger than the thickness of the terminal portion (including the reinforcing portion 14) of the sheet-shaped conductive path 10. Further, in a state where the holding member 30 is in the release position, the extending end of the fitting plate portion 31 is located behind the contact portion 28 of the terminal fitting 25 in the insertion direction of the sheet-shaped conductive path 10. When displaced to the holding position, the fitting plate portion 31 comes to be positioned below the contact portion 28. Note that the upper surface of the fitting plate portion 31 is parallel to the displacement direction of the holding member 30.

The support portion 32 of the holding member 30 is positioned so as to correspond to the receiving portion 29 of the housing 20 in the width direction. Sheet-like conductive path 1
0 is located behind the insertion direction. Therefore, receiving portion 29
The portion where the sheet-like conductive path 10 is engaged with the hook 15 is kept exposed. The support portion 32 has a receiving portion 29
And a relief recess 34 corresponding to the holding member 3 is formed.
In a state where 0 is displaced to the holding position, the receiving portion 29 is accommodated in the escape concave portion 34. The height of the ceiling surface 35 (pressing portion, which is a component of the present invention) of the relief recess 34 is set at a position slightly higher than the upper end of the receiving projection 29B of the receiving portion 29. The thickness is much smaller than the thickness of the conductive path 10. In addition, a tapered guide slope 36 is formed at the upper edge of the opening of the escape recess 34, and the holding member 30 is connected to the housing 2.
Even if it is shifted downward with respect to 0, the receiving portion 29 is smoothly released and is accommodated in the concave portion 34.

Next, the operation of the present embodiment will be described. When assembling the sheet-like conductive path 10 to the housing 20,
First, the holding member 30 is held at the release position, and in this state, the terminal portion of the sheet-like conductive path 10 is inserted into the housing concave portion 24 of the housing 20 while sliding on the upper surface of the fitting plate portion 31 so that the terminal fitting 25 has elastic contact. Sink under the piece 26 (Fig. 3
See). At this time, the height difference between the upper surface of the fitting plate portion 31 and the lower surface of the contact portion 28 of the elastic contact piece 26 is smaller than the plate thickness of the sheet-like conductive path 10. The sheet-shaped conductive path 10 is positioned rearward in the insertion direction of the sheet-shaped conductive path 10, so that the sheet-shaped conductive path 10 has an oblique attitude with the front end side in the insertion direction facing downward. Also, the sheet-shaped conductive path 1
0 is deeply inserted to the regular position where it abuts against the inner end surface 24A of the accommodation recess 24, the hook 15
Corresponding to the upper surface of the base 29A, and
B and the receiving protrusion 29B is brought into a state corresponding to the receiving protrusion 29B from the front side in the insertion direction. The location where the receiving portion 29 and the hook portion 15 are locked can be visually confirmed from above.

Next, from this state, the holding member 30 is slid toward the holding position. With this slide displacement,
The leading edge of the fitting plate portion 31 goes under the sheet-like conductive path 10 and pushes up the end of the sheet-like conductive path 10. As a result, the sheet-shaped conductive path 10 is tilted and displaced so as to raise the insertion end with the engagement portion between the receiving portion 29 and the hook portion 15 as a fulcrum. And the fitting plate 3
1 pushes up the sheet-like conductive path 10, whereby the elastic contact piece 26 of the terminal fitting 25 is elastically moved upward, and the elastic restoring force causes the contact portion 28 to contact the conductive path 12 with a predetermined contact pressure. Be in touch. As a result, the housing 20 and the sheet-like conductive path 10 are assembled in a conductive state.

At the position where the receiving portion 29 and the hooking portion 15 are locked, as the displacement of the holding member 30 to the holding position progresses, the receiving portion 29 and the hooking portion 15 are housed in the escape recess 34. Go. At this time, the holding member 30 is shifted downward with respect to the housing 20 or the sheet-like conductive path 10
Even if the hooking portion 15 is displaced upward with respect to the holding member 30, the receiving portion 29 and the hooking portion 15 are corrected to the normal posture by abutting on the tapered guiding slope 36 of the escape recess 34. It is accommodated in the escape recess 34 without being caught. Thereby, the displacement operation of the holding member 30 to the holding position is performed smoothly. In a state where the holding member 30 is displaced to the holding position, the ceiling surface 35 of the escape recess 34 corresponds to the upper surface of the hooking portion 15 with a slight gap therebetween. That is, the receiving portion 29
Floating in the direction of dissociation from is prevented.

As described above, according to the present embodiment, when the sheet-like conductive path 10 is assembled to the housing 20,
Since the hook portion 15 of the sheet-like conductive path 10 is hooked in the insertion / removal direction with respect to the receiving portion 29 of the housing 20, even if an external force acts on the sheet-like conductive path 10 in the pull-out direction, the sheet-like conductive path 10 remains in the housing. The assembly state (the contact state between the conductive path 12 and the terminal fittings 25) is reliably maintained without floating with respect to the base 20.

When the holding member 30 is displaced from the release position to the holding position, the hook 15 of the sheet-like conductive path 10
And the receiving portion 29 of the housing 20 are kept locked, so that the displacing operation of the holding member 30 does not hinder the state in which the sheet-like conductive path 10 is prevented from being pulled out. Further, when the hooking portion 15 is locked to the receiving portion 29, the locking portion can be visually checked, so that it is confirmed whether or not the locking portion 15 is securely locked, and the reliability of the retaining function can be improved. it can.

Further, in the state where the hooking portion 15 is locked to the receiving portion 29, the lifting of the hooking portion 15 is regulated by the ceiling surface 35 of the holding member 30, so that the hooking portion 15 and the receiving portion 29 are locked. The state can be reliably maintained, thereby further improving the reliability of the retaining function of the sheet-like conductive path 10.
