Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a pressure contact connector.

[0002]

2. Description of the Related Art Conventionally, as this type of pressure contact connector, the one disclosed in Japanese Utility Model Publication No. 6-62468 shown in FIG. 14 is known. In the press-connecting connector shown in the publication, the upper cover 2 and the lower cover 3 which are separate bodies can be attached to the plate-shaped housing 1 from both upper and lower surfaces. A press-fitting metal fitting 4 is press-fitted into the housing 1 so as to vertically penetrate therethrough, and an electric wire 5 is press-contacted and connected on an upper surface and a lower surface. In terms of work, electric wires are laid on the upper surface of the housing 1 to cover the upper cover 2, and after aligning the position, the upper cover 2 is pressed and connected by pressure. Next, the upper and lower surfaces are turned upside down, electric wires are similarly wired, and the lower cover 3 is pressed to make pressure connection.

[0003]

In the above-described conventional press-connecting connector, the housing 1 and the covers 2 and 3 are separate bodies, so that the workability is not good. In addition, it is disadvantageous in manufacturing costs such as molds, transportation costs, and management costs. The present invention has been made in view of the above problems, and an object thereof is to provide a press-connecting connector capable of reducing the number of parts.

[0004]

In order to achieve the above-mentioned object, the invention according to claim 1 holds a pressure-contact fitting having a pressure-contact blade formed on one of a pair of casings which can be united, and at the same time, the pressure-contact fitting and the other of the pair of casings can be joined together. A press-connecting connector that presses and connects both casings so as to bring them close to each other while sandwiching an electric wire between the casings, and the pair of casings are formed by being connected to each other by hinge pieces and face each other. The structure is provided with a temporary locking lock mechanism for locking the electric wire in a temporary locking state and a final locking lock mechanism for locking the casings in a state where they are combined so as to be close to each other.

The invention according to claim 2 is the same as claim 1.
In the press-connecting connector described in (1), the casing holding the press-connecting metal pieces has the same press-connecting metal pieces protruding and held on both sides, and the other casing is provided so as to face each of the two surfaces.

[0006]

In the invention according to claim 1 configured as described above, the electric wire is placed on the pressure contact blade of the casing holding the pressure contact metal fitting, and the hinge piece is bent to move to the position where the other casing faces. Then, the temporary locking lock mechanism temporarily locks. After that, the two casings are pressed against each other, and the electric wire sandwiched between them is pushed into the press contact blade to make a press contact connection, and are united by the main locking mechanism.

By the way, when the hinge pieces are integrated, it is possible to rotate the hinge pieces to directly combine them, but in this case, the casing is drawn while drawing an arc on the press contact blade. In some cases, good pressure contact may not be possible due to the difference in radius from the fulcrum. However, once the two casings are brought into the temporarily locked state in which they face each other and then shift to the fully locked state, they are linearly pressed against all the pressure contact blades.

Further, in the invention according to claim 2 configured as described above, the electric wire is placed on the press-contact blades protruding from both sides of the casing holding the press-connecting metal, and the other casing is faced from both sides. Press and connect while pressing and connecting.

[0009]

As described above, according to the present invention, since the hinge pieces are integrated, the number of parts is reduced and
Once the casings are pressed against each other after the temporary locking state in which they face each other, the pressure contact is performed by the linear movement, and it is possible to provide the pressure contact connector capable of performing the better pressure contact connection work.

Further, according to the second aspect of the invention, since the pressure contact work is performed from both sides of one casing, the pressure contact connection can be made at two places by one pushing operation, and the use of both sides saves the work. It also becomes a space.

[0011]

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view showing a press-connecting connector according to an embodiment of the present invention, and FIGS. 2 and 3 are side views showing a joining process.

In the figure, four ridges 21a and 21b are formed side by side on the upper surface and the lower surface of the main body 20, respectively, and the upper surface and the lower surface are formed in parallel with each other. The upper surface of each of the ridges 21a and 21b is a concave surface that draws an arc, and can be closely attached along the outer peripheral surface of the electric wire 50 that is pressure-contacted and connected. The pressure welding metal fitting 10 made of each strip-shaped metal piece has notches formed at the upper end and the lower end to form the pressure welding blade 1.
1a and 11b are formed and press-fitted into the main body 20 so as to pass through the upper and lower ridges 21a and 21b, and the press contact blades 11a and 11b at both ends are projected and held on the respective ridges 21a and 21b. Has been done.

On the other hand, each of the covers 40 is formed so that the upper and lower surfaces of the main body 20 can be united with each other so that the ridges 21a, 21a,
21b is formed with electric wire housing grooves 41a, 41b capable of accommodating the ridges 21a, 21b and the electric wire 50, and also faces the pressure contact blades 11a, 11b in the respective electric wire housing grooves 41a, 41b. Same pressure contact blade 1 at the position
Grooves 41a1, 41b1 into which the edges of 1a, 11b can be inserted
Is formed. In the present embodiment, a double-sided type in which the covers 40, 40 are combined on the upper surface and the lower surface of the main body 20 is applied, but the double-sided type is not necessarily used, and one surface of one main body 20 is used. It may be a single-sided type in which the cover 40 is attached to the. In this case, the crimping metal fitting 10 does not penetrate the main body 20, but the crimping blades may be arranged in the lateral direction, and the plurality of electric wires 50 arranged next to each other may be crimped and connected. In addition, although the main body 20 is formed with the ridges 21a and 21b and the cover 40 is formed with the wire receiving grooves 41a and 41b,
Each half-circular groove is formed and the electric wire 50
You may make it form the cylindrical part holding.

Regarding the press contact blades 11a and 11b,
Basically, it suffices that wiring can be performed while tearing the coating of the covered electric wire, and the shape of the slit portion can be appropriately modified. As shown in the drawing, the covers 40, 40 are connected to the opposite side edges of the main body 20 by hinge pieces 30. This hinge piece 30 is simply the cover 4
The length is not long enough to rotate the 0 and 40, but is sufficiently long. Therefore, as will be described later, the cover 4
It is formed with a margin that allows the 0 and 40 to be rotated so as to be once away from the main body 20 and face the main body 20 and then to approach the main body 20 from this state.

In the present embodiment, the hinge pieces 30 are formed one by one in the middle of the main body 20, but as shown in FIGS. 6 and 7, two hinge pieces 130 are provided at both ends of the main body 120. Can be changed as appropriate. Further, as shown in the figure, the cover 140 may be formed on the same side surface of the main body 120. Cover 4
Two loop-shaped lock pieces 42 are formed on the side surfaces of the 0 and 40 opposite to the hinge pieces 30 toward the side surfaces of the main body 20. On the other hand, the lock piece 4 is provided on the side surface of the main body 20.
2 is a temporary locking lock protrusion 2 that can be formed on the loop portion
2 is formed. Further, a similar main locking lock projection 43 is formed on the side surface of each cover 40 on the side where the hinge piece 30 is formed.

By thus forming the temporary locking lock projection 22 and the final locking lock projection 43 on the side surfaces of the main body 20 and the cover 40, the cover 40 is locked in two steps. That is, the electric wire 50 is placed on the ridges 21a and 21b of the main body 20 so as to intersect the press contact blades 11a and 11b, and the hinge piece 30 is bent to rotate the cover 40 so as to face the main body 20. When moved, first, the tip of the loop-shaped lock piece 42 is locked to the temporary locking lock projection 22 formed on the side surface of the main body 20. At this time, the electric wire 50 is held by being sandwiched between the pressure contact blades 11a and 11b and the covers 40 and 40 between the main body 20 and the covers 40 and 40 which face each other. This state is shown in FIGS.

Next, when the covers 40, 40 on both sides are pressed so as to be close to each other, the electric wires 50 placed on the press contact blades 11a, 11b are inserted into the electric wire receiving groove 41 of the cover 40.
After pressing into the a and 41b, the pressure contact blades 11a and 11b
Cuts the coating of the electric wire 50 and press-connects. At the same time, the loop-shaped lock piece 42 is locked to the main locking lock protrusion 43 formed on the side surface on the opposite side of the main body 20. In this state, as shown in FIG. 4 and FIG.
0 and the covers 40, 40 are in close contact with each other to be in a united state.

In the present embodiment, the covers 40, 40 are symmetrically connected to both side surfaces of the main body 20, so that the main body 20 and the cover 40 have a substantially symmetrical shape.
As long as they can realize a temporary locked state in which the electric wire 50 is sandwiched between them and a main locked state in which the main body 20 and the cover 40 are locked together in a state of being brought close to each other. The locking structure itself can be appropriately modified. For example, in the example shown in FIGS. 6 and 7, the cover 14
0 and 140 are connected to the same side surface of the main body 120, and are locked to the opposite side surface by a lock piece 142. Therefore, the lock pieces 142 are not provided at positions opposite to each other, but the upper cover 140 is provided at two positions so as to engage with both ends of the main body 120, and the lower cover 140 is inserted between them. The lock piece 142 is provided at one place.

On the other hand, in the above-described embodiment, the lock piece 42 of the cover 40 on the side opposite to the side on which the hinge piece 30 is formed is locked, but in the example shown in FIGS. 6 and 7, the hinge is used. A lock piece is also required on the side of the piece 130.
Lock pieces 123, 123 are formed between the hinge pieces 130, 130 toward the side of 40. In addition, the cover 140
The temporary locking lock projection 124 and the main locking lock projection 125 are formed on the side surface of the main body 120 corresponding to the lock piece 142 of the main body 120, and the temporary locking lock projection 125 and the main locking lock projection 125 are formed on the side surface of the cover 140 corresponding to the lock piece 123 of the main body 120. A stop lock protrusion 144 and a main lock lock protrusion 145 are formed.

First, the ridges 121a, 121 of the main body 120
The electric wire 150 is placed on the surface b so as to intersect the press contact blades 111a and 111b, and the cover 140 is rotated so as to face the main body 120 so that the hinge piece 130 is bent.
At this time, the lock piece 123 is locked to the temporary locking lock projection 144 on the side surface of the cover 140 on the hinge piece 130 side, and the lock piece 142 is locked to the temporary locking lock projection 124 on the opposite side. Then, the electric wire 150 is inserted between the main body 120 and the covers 140, 140 facing each other, and the pressing blade 111a,
It is sandwiched and held between 111b and the covers 140, 140. This state is shown in FIGS.

Next, when the covers 140, 140 on both sides are pressed so as to be close to each other, the pressure contact blades 111a, 11 are pressed.
After pushing the electric wire 150 placed on the wire 1b into the electric wire receiving grooves 141a, 141b of the cover 140, the press contact blades 111a, 111b cut the coating of the electric wire 150 to make a press contact connection. At the same time, the lock piece 123 of the main body 120 is fixed to the main locking lock projection 145 of the cover 140.
The lock piece 142 of the cover 140 is locked to the main body 120.
The main locking lock projection 125 is locked. That is, the covers 140, 140 of the main body 120 are engaged with each other on both side surfaces thereof, as shown in FIGS.
0 and the covers 140, 140 are in close contact with each other to be in a united state.

In this way, when the pressure contact blades 11a and 11b are projected to the main body 20 which holds the pressure contact metal fitting 10, the electric wire 50 is sandwiched between the main body 20 and the cover 40 and the cover 40 are pressed against the main body 20, thereby performing the pressure contact connection. , Make the cover 40 face the main body 20 with the hinge piece 30 having a margin,
By temporarily pressing the pipe in a temporarily locked state and then pressing it straight, workability is improved by the integrated body 20 and cover 40, and good pressure contact connection is performed by avoiding pressure contact connection by a rotating operation. be able to.
