Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides two strong and durable electrical wire terminal connections.
It is used for plug-in connectors that conduct tt.

Conventionally, the connectors on this shelf have only two press-contact points, and if one of them acts as a press-contact at the end of the wire, the connection will be incomplete and there is a risk of malconduction. However, the mechanism also had many drawbacks, such as the difficulty of automatic multiple-seat processing, resulting in high costs.

Therefore, the present application has been made to eliminate the above-mentioned drawbacks, and improves the reliability of the electrical and mechanical connection function by independently press-bonding the upper, middle, and lower parts of one tIc wire terminal, respectively. Moreover, the present invention aims to provide an excellent plug-in connector that is easy to plug in, uses a small amount of materials, can be automatically and continuously processed, is small, easy to use, and has mechanical and economical effects such as low cost.

No more below! One embodiment of the eye will be explained with reference to the drawings. In Figs. 1, 2, and 8, l is an internal metal fitting, which is formed by bending a single spring plate, and this internal metal fitting l is formed by bending a single spring plate.
1& is the base, lb and la are the respective protruding parts. 2 is a lower impeachment piece, which has an elongated U-shaped slit extending from around the guide step 8 extending to the protrusion 4 at the front of the carrying part 10, and a plate-shaped upper impeachment piece 2 formed inside the slit. The tip of the wire protrudes diagonally downward from the inner wall 21, and the tip is positioned between the upper impeachment piece 5 and the protrusion 4, so that it can be pressed against the wire along the trajectory of the wire end 14 inserted through the guide hole 9. 1a, and the tip of the wire terminal 14 is connected to the ttti corrugated plate 12.
It comes into pressure contact with the guide groove 13 of the wire, and its tip bites into the wire to prevent it from being pulled out, and its flexibility and large elasticity make it easy to insert the wire, and the wire can be pressure-welded without strain. thick? ! Even if the wires and wires are repeatedly reused alternately, the pressure contact force does not decrease.Furthermore, the material manufacturer has created a state in which the middle of the spring strip of the protruding portion 1a is hollowed out. There is no increase in the amount because it is composed of
Moreover, regarding processing, since the upper slit 10 and the lower slit 11 can be formed all at once at the same time as the slit processing, there is no increase in the number of steps. Reference numeral 4 denotes a protrusion, which is placed below each lead-out glo and strongly presses the tip of the wire terminal 14. Reference numeral 5 designates an upper impeachment piece, which has the same effect as the above-mentioned upper impeachment piece 2 by folding back the front end of each take-out Mte and positioning its tip diagonally downward toward the inner wall 21 of the internal fitting l. Reference numeral 6 denotes a support wall, which supports the tip of the guide hole 9 from the outside so as to wrap around the folded portion 7, and supports and fixes the take-out portion 1c. Reference numeral 7 denotes a folded portion, and the tip portion of the protruding portion 1c is bent inside the inner fitting 1 to form the upper folding piece 5. Reference numeral 8 denotes a guide step, which has a smooth circular shape so that when inserting the inner fitting 1 into the inner hole 17 of the insulating cap 16 through the opening, the tip of the support wall 6 will not slide against the inner wall surface and interfere with insertion. The protrusion 8 leads and pushes it open to facilitate its insertion. 9 is a guide hole, and the bringing-out part 1a
5. Upper impeachment piece. The lower elastic piece 2, the protrusion 4 provided at the bottom, and the guide groove 13 are arranged in parallel in a straight line to guide and support the wire end 14, and the wire end 14 is completely inserted into the position along its trajectory. Connect properly and secure to prevent movement forward, backward, left, right, and up and down. Reference numeral 10 denotes an upper slit, which is completely slit from the bent part of the support wall 6 to the tip of the support wall 6, which is located on a straight line between the guide holes 9, and is in instant contact with the support wall 6. Each folded portion 7 is supported. Reference numeral 11 denotes a lower slit which completely cuts between the respective brought-out portion ICs to the tip thereof, and is divided into portions so that the respective brought-out portion ICs are not affected by each other. Reference numeral 12 denotes a wL waveguide plate, which has a guide groove 18 formed therein and is inserted into the space between the brought-out portion IC and the inner wall 21 . Reference numeral 18 denotes a guide groove, which is formed in a circular shape to guide the wire end 14 so that it does not bend left or right and pass through, and to increase the contact area along the wire end 14, which has a circular cross section. There is no need to limit it to a circular shape. Reference numeral 15 denotes an insulating cap, which insulates and covers the internal fitting 1, and the shape, method, material, etc. of the covering may be arbitrary.

16 is a guide cap made of any insulating material [11
It guides the terminal 14 and supports and insulates the i-line after use. 1
Reference numeral 7 denotes an internal hole, which is formed at the back of the insulating cap 16 and accommodates the internal fitting l. Reference numeral 18 indicates an insertion port, which is a hole provided in parallel to the guide cap 16. 19i is the upper stage, and is used to lock the inner ring 41 and the guide camp 16. Reference numeral 20 denotes a locking portion, which has a protrusion formed at the tip of the guide cap.
19 and lock it. 2÷ is a voltage detection hole, which is provided at the lower part of the conductive wave tf12, and a voltage detection needle is inserted into this hole to check.

As mentioned above, the front vehicle has a terminal body in which a waveguide plate 12 is incorporated in a single piece T of the inner metal fitting L that connects a large number of σ terminals 14 with a single spring plate, and is inserted into the insulating cap 15. It has a structure that allows automatic continuous processing with a small amount of metal, and is very economical because it can provide an easy-to-use product at a low cost. Two eleven! Because it prevents unplugging in the il place, the conductive connection is perfect and has excellent durability.
Even in the case where the protrusion 4 is not reached when the protrusion 4 is inserted, the two elastic pieces can be pressed against each other, ensuring reliable electrical conduction, and has excellent electrical and mechanical functions.

In addition, as shown in FIG. 5 in the figure, when an insulating cap 15 made of a material having enough durability to withstand the overall pressure contact force of the upper elastic piece 5, the lower elastic piece 2, and the protrusion 4 is used. In this case, if the base part la and the protruding part 1b are deleted and the protruding part IC and the conductive waveguide plate 12 are assembled into the internal hole 17, it is the same as the present application.
It also has the potential for practical application of excellent application products with functions and features.
