Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a support wall 4 that wraps around the outer side of the bending portion 7 of the pressing piece when the wire end 17 pushes apart the pressing piece 8 and the pressing part 5 and inserts the wire end 17. The present invention relates to a plug-in connector that is integrally connected by engaging and supporting the connectors, thereby making the connection and locking effect durable.

Traditionally, this type of product has a complex structure and a large number of parts, making fully automated production impossible, requiring some manual processes, and of course, the processing speed is low, and the large shape makes it difficult to fit into a narrow box. It had many disadvantages that made it impractical, such as being difficult to use indoors and being expensive, so it did not become popular.

Therefore, in order to eliminate the above-mentioned drawbacks, the present application reduces the number of parts, downsizes the shape of each part, strengthens the pressing force and durability, and creates a structure that can be produced fully automatically.
This provides a product with reliable connection and low cost.

Hereinafter, one embodiment of the present application will be described with reference to the drawings. Reference numeral 1 is a spring board, and the same number of vertical slits 18 and 19 are provided on both sides of one spring board, and the slits 19 are bent from around the base. Bottom part 20
is formed, and its tip is bent diagonally inward to form a dogleg-shaped pressing part 5, and its tip is bent inward to form a pressing piece bent part 7; 8, which forms one base extending from around the bottom part 20 to the pressing piece 8, and the other is bent to form the surface part 2, on which guide holes 3 matching the slits 18 and 19 are arranged in parallel. , a support wall 4 is formed which is bent diagonally downward and inward from around the base of the slit 18, forming a series of integral base bodies that constitute many functions. 2 is the surface part, and the spring substrate 1
When one side of the cap is bent and formed, a guide hole 3 is arranged in parallel thereto, and the cap is inserted into the cap 11, the inner hole 1
5. It is locked to the upper wall 14 of 5. 3 is a guide hole, and the number of slits 18 and 19. Holes slightly larger than the wire diameter of the electric wire terminal 17 are arranged in a row at positions that match the positions. 4 is a support wall, and slit 1
The wire terminal 1 is bent from the base of the wire 8 toward the lower part of the oblique inner side, and is formed so as to wrap around the outer shape of the bent portion 7 of the pressing piece.
It supports the elastic body 6 against the action of opening outward due to the insertion pressing force of 7, strengthens the pressing elastic force of the pressing piece 8 and the pressing part 5, and maintains durability performance. Reference numeral 5 denotes a pressing portion, which bends the lower part of the elastic body 6 inward in a dogleg shape and elastically presses the wire end 17. 6 is an elastic body, and slit 1
9 to the tip of the pressing piece 8, which forms the base body forming the mechanism of the bottom part 20, the pressing part 5, the pressing piece bending part 7, and the pressing piece 8, and is an elastic pressing part. Has a function. Reference numeral 7 denotes a pressing piece bent portion, which is bent deeply diagonally downward and inward to form a pressing piece 8 along the inside of the support wall 4 . Reference numeral 8 denotes a pressing piece, which elastically moves around the pressing piece bent portion 7, and its tip presses and locks into the wire end 17 so as to prevent it from coming off. Reference numeral 9 denotes a conductive wave plate, which has grooves 10 perpendicular to each guide hole 3, and is assembled between the inner wall of the spring substrate 1 and the pressing pieces 8 and 5 to form a connecting terminal. 11 is a cap, in which a mold is heated and attached to an insulating material;
This is heated to gel, and immediately after that, the necessary markings are stamped on the surface to mark it, and it is removed from the mold and molded to form an opening 12 in the shape of a circular opening 13 into which a connecting terminal and a wire end 17 are inserted. The inner part of the upper wall 14 is formed narrow to enable guiding of the wire end hole 17, and the inner part of the upper wall 14 is provided with an internal hole to enable complete insulation, and to prevent the connecting terminal once inserted from coming out.
When inserting a connecting terminal, it can be easily inserted by heating it to make it soft. Reference numeral 13 denotes a circular opening, which allows the position and number of the guide holes 3 to be easily seen, and also serves as a guide for the insertion work into the guide holes 3. 18 is a support wall slit, which is the number of guide holes 3 and slits 19; The slits 18 are cut vertically from around the bent portions according to their positions, so that no pressing force is applied to the surface portions 2 as a whole, but the slits 18 are not necessarily required. Reference numeral 19 denotes an elastic body slit, which is completely cut out from around the bottom 20 to the tip of the pressing piece 8 in order to enable the elastic bodies 6 to move individually, and each functions as a unit of 17 electric wire ends. Even if single wires with different thicknesses of the wire ends 17 are inserted alternately, the elastic action works individually and the pressing effect can be completely improved. 20 is the bottom part, and the wire end 17 to be inserted is adjusted to a certain length, and the inner hole 1 is inserted.
To embed and fix a conductive wave plate 9 without damaging the bottom surface of 5. In addition to the above-mentioned effects, the support wall 4 has a shape that faces diagonally downward and inward along the upper part of the obliquely formed elastic body 6;
When the connecting terminal is inserted through the opening 12, the tip of the support wall 4 does not get caught, and the opening 12 widens and opens along the diagonal shape, allowing high-speed insertion processing using an automatic machine.

As mentioned above, the present application has many functions in an integrated spring plate due to the effect of the support wall 4,
Because each function can be fully demonstrated, the number of parts is small and small, with only 3 parts, and all can be produced using commercially available processing machines.The assembly process can be fully automated, and the 2-point press is reliable. It has many features such as being small, lightweight, inexpensive, and easy to plug in, with good conductivity and durability.

As described above, in the present invention, when it is desired to connect a plurality of wire terminals 17 to each other, when they are inserted through the guide hole 3, a pressing piece 8 is attached to each wire terminal.
The tip of the wire and the pressing portion 5 of the elastic body 6 are brought into pressure contact at two upper and lower locations, respectively, to achieve electrical conduction between the wire ends, resulting in the effect of obtaining high connection reliability.

Furthermore, in the above case, when the inserted wire end pushes the tip of the pressing piece 8 or the pressing part 5 of the elastic body 6 toward the side opposite to the substrate, the bent part 7 of the base of the pressing piece 8 is pushed against the support wall. 4, the elastic force of the pressing piece 8 can be directly applied to the tip of the pressing piece to ensure that the tip is pressed against the wire terminal 17.
Further, in the case of the elastic body 6, the bent part 7 at the upper end is supported by the support wall 4 as described above, and the lower end is supported by the bottom part 2.
0, the elastic force of the dogleg-shaped elastic body 6 itself, the reaction force of the surface part 2 due to the surface part 2 being pushed up via the upper part of the elastic body 6, and the elastic force of the dogleg-shaped elastic body 6 itself. The bottom part 20 through the lower part of the moving body 6
The three forces together with the reaction force of the bottom part 20 caused by the pushing down push the pressing part 5 toward the wire terminal 17.
This has the effect of making it possible to make a firm pressure contact and making the reliability of the connection extremely high.

Furthermore, in the above case, even if the wire ends 17 are thick and thin, each wire end 17 can be pressed individually with each part divided by the slit 19 in the pressing piece 8 and the elastic body 6, so that the wire terminals 17 can be stably pressed. This has the effect of achieving a conductive state.

Furthermore, even though the device has the above-mentioned features, since its structure can be formed by bending a single sheet metal, it is easy to manufacture and can be provided at low cost.
