Since it is urged toward the side, the pressing force is increased, and an electric wire connector in which the contact state is maintained for a long life is provided.
Another object of the present invention is to provide a convenient electric wire connector not only when a plurality of electric wires are inserted but also after insertion.
Other objects and advantages will be readily apparent from the drawings and the following description associated therewith.

  The electric wire connector according to the present invention comprises a pair of left and right conductive plates arranged opposite to each other, and a conductive tool formed of an arcuate conductive member bottom formed to connect the bottom sides of the conductive plates to each other.

In the state where the spring member is located outside the pair of left and right conductive plates, and the spring member bottom is located outside the conductor bottom, the conductive tool and the spring tool are arranged on the hollow cylindrical portion of the insulating cap. Stored,
In the storage state in the insulating cap, both the conductive tool and the spring tool are constricted on the opening side of the insulating cap, and the wire terminal is inserted into the left and right conductive plates from the opening side. The distance between the plates is widened against the force of the spring material that is located outside each of the conductive plates and has a constricting force. It is designed to adhere to both sides of the wire end

In the adjacent direction (the depth direction in FIG. 4) of the conductor B, a plurality of right conductors 1 and left conductors 2 are continuously formed using an integral material. Reference numeral 6 denotes a slit for separating a part on the upper side of each of the right conductive plate 1 and the left conductive plate 2, and the wire terminals 21, 21 are connected to a connection groove 19 having a concave cross section as shown in FIG. 5. So that each left conductor 2 and each right conductor 1 facing each other are functionally separated from each other in a functionally wide and narrow manner. . Note that conduction between adjacent ones is also performed at the bottom 9 of the conductive tool.

C is a spring tool, which uses a spring material (any well-known material such as stainless steel or spring steel having high elasticity), is formed by folding the intermediate portion C1 of one plate into two using a pressing means, and the upper end 13 And the upper position slightly lowered to the bottom 10 as shown in FIG. 3 is narrowed inward. A curved portion (U-shape) that becomes the bottom portion 10 of the spring tool is used as a resilient source.
The spring tool C is composed of a pair of left and right spring members 11 and 12 arranged in opposition to each other, and a portion that functions to sandwich the conductive plates 1 and 2 between the spring members 11 and 12 and press-contact the wires. From the lower part, that is, the three elements of the bottom part 10 of the spring tool that are formed in an arcuate shape (U-shape) that connects the lower parts of the bottom side to each other (consisting of an integral material or separate members) Become.
In the adjacent direction (the depth direction in FIG. 4) of the spring tool C, a plurality of right spring bodies 11 and left spring bodies 12 are continuously formed using an integral material. Reference numeral 17 denotes a slit for functionally separating a part of the upper side of the right spring body 11 and the left spring body 12, and the electric wire terminals 21 and 21 are connected to the inner conductive tool as shown in FIG. In the state in which the individual left spring bodies 12 and the individual right spring bodies 11 are functionally separated from each other so that they can be individually held one by one in the upper part of the connection grooves 19, 19 having a concave cross section in B. Each of the conductive tools B can be elastically clamped.
As shown in FIGS. 2 and 3, both the conductive tool B and the spring tool C have two conductors and two spring bodies arranged side by side in the adjacent direction. May be composed of one conductor and one spring body when configured to be able to insert a plurality of wire terminals 21 inside one conductor, Three or more may be formed continuously.

The spring members 11 and 12 are located, and the spring tool bottom 10 is accommodated outside the conductive tool bottom 9 in a superposed state.
In such a state of being housed in the insulating cap, both the conductive tool B and the spring tool C are narrowed on the side of the opening 18 of the insulating cap as shown in FIG. When the wire terminal 21 is inserted into the left and right pair of conductive plates 1 and 2 as shown in FIG. 1A from the opening 18 side, the distance between the conductive plates is the outside of the conductive plate. The pair of left and right conductive plates are tightly attached to both sides of the wire terminal in response to the force of constriction from both sides of the spring material. And a good conduction state is obtained.
The means for positioning the spring members 11 and 12 on the outer sides of the pair of left and right conductive plates 1 and 2 and positioning the spring tool bottom 10 on the outer side of the conductor tool bottom 9 is shown in FIG. The positional relationship between the two is as shown in FIG. 1B by lowering the conductive tool bottom 9 to the inside of the spring tool C and, at the same time, widening the opening 13 of the spring members 11, 12. It becomes like this. If the retaining spring piece 14 is present in the process of combining, the following occurs.

First, the matter regarding the retaining spring piece 14 will be described.
The retaining spring piece 14 is projected from a part of the spring tool C toward the electric wire terminal 21 inserted inside the pair of left and right conductive plates, with the conductive plate of the conductive tool B being penetrated, and the tip of the retaining spring piece is The electric wire terminal 21 is pressed against the electric wire terminal to prevent the electric wire terminal 21 from being removed.
More specifically, at least one conductive plate of the pair of left and right conductive plates 1 and 2 is provided with a rectangular insertion hole 5 that is long in the vertical direction as shown in FIG.
In at least one of the pair of left and right spring members 11 and 12, a part of the spring member is cut and raised inward as shown in FIG. Reference numeral 15 denotes a punched hole in which the retaining spring piece 14 is cut out, and reference numeral 14 a denotes a base portion of the retaining spring piece 14. The downward inclination angle of the retaining spring piece 14 makes it easy for the wire end 21 to push open when the wire end 21 is inserted, and its tip directly presses the wire end 21 to lightly bite into the state shown in FIG. The angle is set such that the effect of preventing the wire terminal 21 pressed in step 2 is increased.
The size of the rectangular insertion hole 5 is such that when the B and C are combined in FIG. 4, the retaining spring piece 14 is guided into the rectangular insertion hole 5 that is long in the vertical direction. Therefore, in the combined state where the spring material is positioned on the outside of each of the pair of left and right conductive plates and the spring tool bottom is positioned on the outside of the bottom of the conductive tool, a part of the spring material is cut and raised toward the inside. The formed retaining spring piece 14 is positioned inside the conductive tool through the insertion hole 5 that is long in the vertical direction, and the tip of the retaining spring piece 14 is pressed against the electric wire terminal inserted inside the conductive tool. It is designed to prevent the removal.

  For the assembly of the electric wire connector, the illustrated insulating cap A, conductive tool B, and spring tool C are prepared. The conductive tool B and the spring tool C are combined as described above with reference to FIG. 5 to constitute a conductive tool D as shown in FIG. The conductive cap D is inserted into the insulating cap A from the opening 33 toward the housing chamber 8, and the opening 33 is covered with the transparent cap 23. In that case, the upper ends 3 and 13 located at the upper part of the conductive appliance D are located in the space below the lower slope 7b of the guide piece 7, and are located at the center of the upper ends 3 and 3 and the upper ends 13 and 13, respectively. The funnel-shaped receiving part D1 that coincides with the intermediate part of the guide pieces 7,7. In this state, as shown in FIG. 1 (B), the wire terminal 21 at the tip of the wire 20 is inserted from above to obtain the state of FIG. 1 (A). Then, the upper ends 3 and 3 and the upper ends 13 and 13 of the conductive device D are opened, the entire inner surface of the conductive plates 1 and 2 of the conductive tool B is in close contact with the electric wire terminal 21, and the inner surfaces of the pair of left and right spring members 11 and 12 are The whole area strongly presses the entire outer surface of the conductive plates 1 and 2 inward. Further, the tip of the retaining spring piece 14 directly presses and presses the electric wire terminal 21 and bites lightly. In this state, the state of the entrance / exit dimension of the tip 21a of the wire terminal can be inspected from the outside through the transparent cap 23.

Next, drawings showing embodiments of the present application will be described from different viewpoints.
The wire connector is limited in size and length, and is elongated into two parts using a conductive material. The upper part of the wire connector is fastened. Each of the springs is held in its upper end with a conductive tool opening for easy insertion of the wire end, and a guide piece for fixing vertically in the insulating cap is provided. Fold it in half and squeeze the upper part, hold the upper part with the left and right spring material that is almost matched to the upper part of the back of the connection groove from the left and right, press and hold it, and at the upper end, provide a spring tool mouth opening, A conductive tool is inserted into and attached to this, and a retaining spring piece is provided on one of the left and right spring members to directly press and reinforce the electric wire end, and a conductive instrument configured to be prevented from coming off at its tip is provided with an insulating cap. Fixing housed in a flop.
In order to maintain the fixing state of the conductive device installed in the conductive device storage chamber before use, the guide pieces provided on the left and right sides of the back end portion of the cap opening portion are positioned and supported on the upper surface of the side portion of the conductive device opening portion. Inclination is prevented, and further, the bottom of the spring member is fitted into the recess to assist in prevention of inclination and to be fixed and stored.

  Using a conductive material, fold it in half and squeeze the top, and then squeeze the conductor that holds the wire end in the connecting groove facing the left and right sides. Hold the material in a shape that almost conforms to the outer shape of the back of the connection groove and effectively press and hold it, and install an electrically conductive device that is mounted on a spring device with a retaining spring piece on either the left or right spring material. It was installed accurately and stably in the storage room.

The distance between the bottom of the conductive tool and the top of the connection groove is the same as the overall length of the conductive tool, and the distance between the top of the spring material that presses the back of the top of the piece or the connection groove and the bottom of the spring is almost the same as that of the spring tool. Even if the overall length of both the conductive tool and the spring tool is relatively short, the distance between them is long and the width of the ballistic movement is wide. Does not deteriorate.
In order to attach the conductive tool to the spring tool, if the bottom of the conductive tool is inserted randomly from the opening of the spring tool mouth, the left and right spring materials are pushed open by being guided by the slant wall, and accurately enter the connecting groove. The push-out spring piece is pushed open with and restored at the same time as mounting, and a conductive device is made. Guide pieces provided at the back of the cap opening portion are positioned on the upper surfaces of the right and left side portions of the conductive tool opening to prevent tilting, and the conductive device before use can be fixed and easily inserted into the storage chamber.

The conductive tool bottom 9 is an elastic source and has a frontal shape that is tapered like a glans shape, facilitating insertion and insertion from the spring tool opening 13. Reference numeral 10 denotes a spring tool bottom, which is an elastic source and has a frontal shape that forms a glans shape so that the conductive tool bottom 9 can be covered, fits into the recess 24 and is supported by the guide piece 7 to fix the conductive tool in the storage chamber 8. . Reference numeral 11 denotes a right spring material, which is shaped to match the shape of the back of the connection groove 19 and holds and presses the back of the right conductor 1. Reference numeral 12 denotes a left spring material, which is also shaped to match the shape of the back portion of the connection groove 19 and holds and presses it. However, the pressure can be applied without necessarily matching the shape of the back of the connection groove 19. Reference numeral 13 denotes a spring tool opening, which forms an inclined wall that can be easily inserted from the bottom 9 of the conductor.
Reference numeral 16 denotes a terminal passage hole through which the tip of the electric wire terminal 21 passes. Reference numeral 17 denotes a slit, which is provided with a right spring material 12 and a left spring material 11 for slitting the left and right side portions of the spring tool and individually pressing and pressing the electric wire terminals 21. 18 is a cap mouth opening part, and inserts the electric wire terminal 21 line by line. The shape of the connection groove 19 is not limited to a semicircular shape, and any shape such as a semi-elliptical shape or a half-square shape may be used, or any groove may be provided on either the left or right side, and the other conductor upper inner surface shape may be a flat surface. 20 is a covered electric wire.

The distance between the elastic source of the conductive tool bottom 9 and the upper part of the connection groove 19 that holds the electric wire terminal 21 is equal to almost the entire length of the conductive tool B. Therefore, the load on the conductive tool bottom 9 is small, and the material is steel. Even if it is soft, the spring property does not deteriorate, and therefore, the function of holding the electric wire terminal 21 does not deteriorate even if the attachment and detachment are repeated.
To repeat, the conductive tool bottom 9 is inserted and attached through the spring tool opening 13, the spring tool bottom 10 is used as an elastic source, and the upper part of the left conductor 2 on the left spring material 12 is connected to the right spring. The upper part of the right conductor 1 is held by the upper part of the material 11 and pressed against each other, and the electric wire terminal 21 is clamped by the left and right connection grooves 19.

  The spacing between the spring source of the spring tool bottom 10 and the upper part of the right spring material 11 and the left spring material 12 that presses the back of the connection groove 19 is substantially equal to the overall length of the spring tool arrow -B, and is therefore practically limited. Even within the range of the length of the connector, there is a little elastic load with respect to the elastic source, and there is a margin, and there is no deterioration due to the difference in the wire diameter of the wire terminal 21 and repeated attachment / detachment.

In the step of attaching the conductive tool B to the spring tool C, when the conductive tool bottom 9 having a glans shape is pressed against the spring tool opening 13, it is inserted while sliding on the slant wall, and the retaining spring piece 14 is automatically attached. The push spring material 14 is advanced to the concave portion 24 while being pushed open, and the stopper spring material 14 is restored and the mounting is completed.
Even if the diameters of the terminal passage holes 4 and 16 are smaller than the outer diameter of the electric wire terminal 21 and do not protrude, visual inspection can be performed through the hole from the outside.
One of the right conductor 1 and the left conductor 2 is fixed, and pressure conduction is possible even when the other conductor alone is unilaterally pressed.
Guide pieces 7 provided on the left and right top surfaces of the cap opening 18 are positioned on the left and right upper surfaces of the conductive tool opening 3 to prevent support inclination and fix the storage state before use, so that the wire terminal 21 can be accurately and Can be easily inserted.
