Detailed Description of the Invention

【Technical field】

The present invention relates to a connector with a modular jack used for wiring telephone lines.

[Background technology]

The connection between a modular jack that has been widely used for connecting telephone lines and telephones in recent years and a telephone line that has been drawn into a home has been conventionally drawn out from the modular jack body 2 as shown in FIG. This is done by providing the terminal screw 35 to the base 1 to which the plural lead wires 21 are respectively connected and connecting the telephone line to the terminal screw 35. For this,
In addition to requiring time and effort to connect the telephone line, in the case of 6 poles and 6 cores, 6 terminal screws 35, which require screw processing, will be used.
The cost is high, and the presence of terminal screws 35 has been a bottleneck for the automation of the assembly of the connector with modular jack.

[Object of the Invention]

The present invention has been made in view of the above points, and an object of the present invention is to provide a connector with a modular jack, which is easy to assemble and easy to connect.

DISCLOSURE OF THE INVENTION

The present invention, therefore, comprises a modular jack body, a terminal block, and a base having a surface for engaging the two parts with each other. Positioning of the lead wire drawn from the modular jack body is performed on the base. The terminal block having a plurality of quick-connect terminals into which telephone lines are inserted and connected is provided with a terminal plate that comes into contact with the lead wires when engaged with the base. The connection between the telephone line and the terminal block can be done only by inserting the telephone line due to the existence of the quick-connect terminal, and the connection between the lead wire pulled out from the modular jack body and the terminal block is based on the terminal block. It can be performed only by engaging with the engaging portion of. The present invention will be described in detail below with reference to the illustrated embodiments.
In FIGS. 3 to 3, a convex portion is formed at the center of the surface of the exposed wiring base 1 having wood screw holes 15 formed at four corners.
10 are provided, and a plurality of continuous grooves 11 are provided on the surface and side surface of the convex portion 10 and the surface of the base 1.
The surface of the base 1 has a modular jack body 2
There are provided engaging portions 12, 12 for engaging with each other, two pairs of engaging portions 13, 13 for engaging with the terminal block 3, and an engaging portion 14 for engaging with the cover 4. ing. The modular jack body 2 is provided with protrusions 22 on both side surfaces thereof, and in the illustrated example, it has a 6-pole and 6-core structure, and six lead wires 21 are drawn out from the rear surface. These leads 21 are spring wires 20 for contacting the modular plug.
Is provided integrally with the spring wire 20 or is provided as a separate component from the spring wire 20 and connected to the spring wire 20. Two terminal blocks 3 that can be attached to the base block 1 can be locked together.
Three quick-connect terminals, each of which is composed of a terminal plate 31 and a terminal plate 31, are assembled by press-fitting from the back, and projections 32 are provided on both side surfaces.
On the surface, a push button 33 for releasing the connection is integrally provided for each quick connection terminal, and a hole 34 for inserting a telephone line is provided.
Is provided for each quick-connect terminal. And this terminal block 3
The rear surface is provided with a plurality of openings, and the terminal plate 31 is exposed on the rear surface side. When assembling, the modular jack body 2 is attached to the surface of the base 1 by the engagement of the engaging portions 12 and the protrusions 22, and each lead wire 21 is positioned in the positioning groove 11 of the base 1. Let Then, the terminal block 3 is attached by engaging the engaging portion 13 and the protrusion 32. At this time, each tip of the lead wire 21 is located on the back surface of the terminal block 3, and the terminal plate 31 of the quick-connect terminal provided on the terminal block 3 has a rear surface as shown in FIG. A bifurcated projecting piece 36 protruding toward the side is cut and raised, and the projecting piece 36 fits into the groove 16 formed in the base 1 so as to be orthogonal to the groove 11, so that the terminal block 3 When attached to the base 1, each lead wire 21 is connected to each terminal plate 31. To connect the telephone line to the terminal block 3, it is only necessary to insert the tip of the telephone line with the coating removed into the terminal block 3 through the hole 34. The telephone wire is sandwiched between the locking spring 30 and the terminal plate 31 to connect to the terminal plate 31. The release button 33 may be pushed in to release this connection. Release button
33 presses the locking spring 30 and separates the tip of the locking spring 30 from the terminal plate 31, so that the telephone line can be easily pulled out. The quick-connect terminal consisting of the lock spring 30 and the terminal plate 31 can be connected by inserting two telephone lines so that the feed wiring can be taken. Thus, if the modular jack body 2 and the terminal block 3 are attached to the base 1, the insulating paper 5 is arranged on the convex portion 10, and if necessary, as shown in FIG. Place condenser unit 6 on top of 10. The cover 4 is attached to the base 1 by engaging the protrusions 42 formed on the inner surface thereof with the engaging portions 14 of the base 1. The cover 4 is provided with knockout portions 40 and 41 for forming a notch for inserting a telephone line. For installation, holes 15 are formed in the four corners of the base 1.
Through a wood screw or a recess formed on the back side of the protrusion 10.
A permanent magnet may be arranged on 17 and attached by its magnetic force, or the back surface of the base 1 may be attached to the installation surface by a double-sided adhesive tape. As shown in FIG. 4, the block-shaped terminal block 3 shown here includes a jumper pin 7 that short-circuits each terminal plate 31, and an engaging portion 80 that engages with the protrusion 32. By using the shaped back cover 8, it can be used as a branching connector. Since two telephone lines can be inserted and connected to each quick connection terminal as described above, in this case, it is for six branches. As shown in FIG. 5, a terminal block 38 for connection to a printed circuit board is used as the blocked terminal block 3 as described above.
Using the terminal plate 31 integrally provided with the back cover 8 and the back cover 8 having the hole 81 for inserting the terminal piece 38, the back cover 8 can be connected to the printed circuit board. be able to. Furthermore, as shown in FIG.
In addition to using the terminal plate 31 that does not have the protruding piece 36,
If the back cover 8 is attached, two telephone lines can be connected at each quick-connect terminal, so that a relay connector can be constructed.
