Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an insertion device that enables light and easy insertion when inserting an electric wire terminal, provides reliable, strong, and permanently connected conduction, and prevents damage to the IM electric wire terminal. It concerns a type connector.

Conventionally, in this type of plug-in connector, the conductive plate and the inside of the box are formed into a complicated structure, and in addition, a piece of pressure spring is crimped to the conductive plate.

Products with caulking processing are very complicated in mass production equipment and require a lot of labor, and are therefore not only expensive, but also when using a single-piece compression spring, after inserting the thick wire terminal, When a thin wire end is replaced, there are many drawbacks, such as the suppression spring weakening quickly and causing poor contact.

Therefore, the present invention has been made to eliminate the above-mentioned drawbacks, and provides a plug-in connector that has high reliability in electrical and mechanical connection of wire terminals, and also has the economical effect of being able to be provided at low cost. This is what I am trying to do.

An embodiment of the present application will be described below with reference to the drawings.

1 is a spring body, which is formed by bending a single spring plate. In this spring body 1, 1a is a base, and lb and lc are respective protruding parts. Reference numeral 2 denotes the inner wall of the base 1a, and the conductive plate 14 and the wire end 18 are collectively sandwiched between the impeachment pieces 5 and 6, and the contact is firmly and permanently maintained, and the tip of the impeachment pieces 5 and 6 It also functions to prevent the terminal 18 from being removed. Reference numerals 8 and 4 indicate cutting lines, and the base portion 1a is cut into a thin strip leaving the connecting portion 8 at the center so that the impeachment pieces 5 and 6 act individually, so that each spring body 1 is individually impeached as a whole. It is what made the action possible. Reference numeral 7 denotes a guide hole, which is provided in parallel with each of the lead-out portions 1&, so that the wire end 18 can be inserted and connected to the groove portion 15 formed in the impingement piece 5.6 and the conductive plate 14 accurately. Reference numeral 8 denotes a connecting portion, in which the plurality of spring bodies 1 constitute a connecting body by leaving a little space between the respective cutting lines 8 and 4 in the center portion of the base portion 1a. Reference numeral 9 denotes an insulating cap, which is made of an insulating and stretchable material, and has an opening lO at the top, and a step 16 at the back of the cap so that the connected body of the spring body 1 once inserted can be pulled out. When the spring body 1 incorporating the conductive plate 14 is inserted through the mouth opening 10, the spring body 1 comes into contact with the inclined wall portion 17, the step 16 is pushed open, and the spring body 1 easily slides in. Reference numeral 11 denotes an internal hole, which is formed in common with the opening 10 of the insulating cap 9, and is formed in a shape and size such that the connecting body of the spring body 1 can be inserted therein with sufficient margin. 12 is a covered electric wire. 18 is the electric wire terminal.

14 is a conductive plate, and as shown in FIG. 4, grooves 15 are formed at the same pitch as the guide hole 7 and the impeachment pieces 5 and 6;
It is configured to be aligned with the inner wall 2 and supported by the tips of the built-in impeachment pieces 5 and 6, so that each N-wire terminal 18 is accurate and strong and does not move, and furthermore, the contact area is large and a stable conductive effect can be obtained. It will be done.

However, if a guide hole common to the guide hole 7 and the groove section 15 is formed in the take-out part 1o, and the tip of the wire terminal 18 is inserted into this hole to prevent it from moving, it is possible to form four planar electric plates. Can be used. 16 is a step. 17 is a slanted wall.

To describe the features of this plug-in connector, as shown in Fig. 8, cutting M8, 4 is used to cut the entire connecting part 8, leaving only a small part, so that each spring body l is completely independent. If the m111 end *18 is inserted, the impeachment piece 5.6 and the base 1a are brought out 1b.

1at- Since the impeachment action acts on the entire spring body 1, the pressing action of the impeachment pieces 5 and 6 feels soft and easy to insert.
The pressure contact force does not weaken, the wire terminal 18 is not damaged, and two places on one wire terminal 13 are pressed to prevent the wire from being pulled out, so there is no possibility of permanent contact failure. Therefore, it is suitable not only for metal wires but also for relatively easily damaged wires such as plastic wires, and in this case, it is appropriate to use a plastic material for the conductive plate. Note that when the spring body 1 is made of a plate made of a highly conductive material, the conductive plate 14 is unnecessary if the guide hole 7 is formed at the same position as the inner wall 2.

Describing the processing of the plug-in connector of the present application, the spring body 1 and the conductor'? The lI plate 14 can be mass-produced fully automatically and continuously using a multi-forming machine or a press machine using a material with a long coil winding, and the insulation cap 9 can also be mass-produced fully automatically and continuously using an ENVI molding machine. be.

As mentioned above, each component can be easily produced in a short period of time, and each vibrator is replenished at once to each vibrator, and each of the parts is then aligned and sent out to an automatic assembly machine, where the conductive plate 1 is attached to the spring body 1.
4 is automatically inserted into the mouth opening 10 of the insulating cap 9 that is aligned and fed from one side, and then printed on the surface of the insulating cap 9 to complete the hole making process. Then, the products that are sent to us are automatically packaged and the products are delivered. As described above, it has the great advantage of being able to be manufactured at low cost using a series of automatic processing machines, and naturally it can be provided at low cost.

Claims (1)

[Scope of Claims] Each of the plate-shaped iJJ capitals has a protruding part connected to the base in a bent manner toward one side, and one of the two protruding parts A plurality of guide holes are provided in parallel so that the wire terminals can be inserted into the space surrounded by the base and the supporting ridges, respectively, and each impeachment piece is inserted into the space at the two free ends. The impeachment pieces are arranged in a folded manner in a row toward each other, and each tip of each of the impeachment pieces is inserted into the space through the guide hole. Place the wires along the insertion locus of the wire ends so that they can be press-contacted with the wire ends. Moreover, the base, the two protruding parts, and the two impeachment pieces are made by bending a single spring plate and forming a long cutting line excluding the connecting part left at the base.
