Description

Wire Terminals for Lighting Fixtures {Terminal of lighting fixtures}

The present invention relates to a terminal of lighting fixtures (terminal of lighting fixtures), and more particularly, to the connection of the twisted pair and the connector for the lighting fixture with improved grounding structure of the terminal.

In general, as a terminal used to connect between stranded wire and disconnected wire, a wire connecting terminal as shown in FIG. 10 is known. However, although the stranded and disconnected wires are specially distinguished, improvements in wire connection terminals have been required for reasons of structural complexity and poor grounding conditions.

Let's look at this in detail.

That is, the structure of the wire connection terminal is formed by an upper terminal 200 having a connection space, a lower terminal 230 assembled at the bottom of the upper terminal 200, and formed by the upper and lower terminals. Consisting and energizing member 210 mounted in the connection space to be made, and the opening and closing member 220 for pressing the energizing and the holding member 210 to enable the insertion and release of the wire.

The conventionally known wire connecting terminal of such a structure

First, an elastic connecting piece having elastic force is formed to improve the folding force of the stranded wire. However, since the bottom of the stranded wire is supported only by the elasticity of the elastic connecting piece, the connection force for preventing the stranded wire from falling off is insufficient.

Secondly, the structure that the elastic connecting piece and the corresponding pressing member in the inner connection space of the terminal main body is installed in the upper space by pressing the twisted wire by pressing the pressing piece in the upper part, but the structure is complex, the assembly is complicated Fall, and this leads to a problem that the manufacturing process and manufacturing cost increases.

Third, even though the structure is complicated, the grounding structure is not provided. Therefore, when the grounding structure is added, the complexity increases.

Accordingly, in view of the above problems, there has been a need for a wire connection terminal having a grounding structure, while improving the connection strength of the stranded wire, simplifying the structure of the wire connection terminal.

The present invention has been made in view of the necessity for such a problem that the conventional wire connection terminal has in view of providing a wire connection terminal having improved connection strength, simplified structure, and improved assembly.

The present invention is also aimed at improving the grounding structure of the wire connection terminals in addition to the technical problem of reinforcing the connection force for the stranded wire.

In particular, the present invention is to provide a new connection structure for increasing the connecting force when the stranded wire between the finger member and the energizing member is the main point.

According to this figure, the present invention is largely composed of the terminal body 10, the energizing member 20, the finger member 30, and the paper holding member (40).

The terminal body 10 includes a connection space 11 formed of a blocking portion 16 having a stranded wire insertion hole 12 and a single wire insertion hole 14, and a locking hole 13 formed above the connection space 11. And a button lifting hole 15.

The energizing member 20 has a c-shaped cross section for insertion and mounting in the connection space 11, and a plurality of button through holes 22 are formed in the upper portion of the cross section, and one of the + type openings 24 is provided. The cutout is formed, and one outer edge of the opening 24 protrudes the catching piece 21, and a predetermined catching hole 23 is formed in the lower portion.

The holding member 30 is bent in the opening portion 24 of the conducting member 20 by being bent upwardly while forming a stone piece 32 so as to be stuck in the conducting member 20 to support the stranded wire and the disconnected wire. It is seated, the other end is bent to be bent in the through hole 22, the lower portion to form a locking piece (31).

The holding member 40 is integrally formed at the lower end to be liftable on the through hole 22 and the opening 24, and forms a half-hanging jaw 42, and the upper end forms a button 41.

3 is a plan view of the present invention wire connection terminal, Figures 4a and 4b is a cross-sectional view taken along line AA of Figure 3, Figure 4a is a cross-sectional view before the twisted pair connection of the present invention wire connection terminal, Figure 4b is a wire connection terminal of the present invention Is a cross-sectional view of the pressing member pressed for the twisted pair connection. 5 is a cross-sectional view taken along line C-C of FIG. 3 to show a stranded connection state of the inventive wire connecting terminal, and FIG. 6 is a cross-sectional view taken along line B-B of FIG. 3 to show a mounting state of the finger member.

In the assembly structure of the present invention made as described above, as shown in FIGS. 2, 4A, and 6, the engaging piece 31 of the support member 30 is caught in the lower engaging hole 23 of the conducting member 20. At the same time, the projection piece 32 is horizontally positioned on the opening 24 of the energizing member 20 while its end portion is positioned slightly higher than the opening 24.

An appropriate number of grounding structures (hereinafter referred to as grounding structures) of the entirety of the finger member 30 coupled to the energizing member 20 through the stranded wire insertion hole 12 of the terminal body 10 may be provided in the connection space 11. And insert one end portion into close contact with the blocking portion 16 of the connection space 11. At this time, the engaging piece 21 of the energizing member 20 protrudes and is supported by the engaging hole 13 of the terminal body 10, and the engaging piece 31 protruding downward of the energizing member 20 is connected. It is in close contact with the bottom of the space 11 is horizontally hung in the locking hole (23).

Therefore, the stopper member 30 is prevented from being separated from the energizing member 20 by the locking piece 31 of the stopper member 30, and the energizing member 20 is caught by the locking hole 13. Since the separation is prevented by 21, the ground structure consisting of the energizing member 20 and the finger member 30 is firmly mounted to the terminal body 10.

Thereafter, the pressure-sensitive member 40 is pushed and assembled by pushing the lower half of the elastic locking jaw 42 through the button lifting hole 15 of the terminal body 10.

Of course, the disassembly of the energizing member 20 is first detached with the finger member 30 by being detached by pushing the engaging piece 21 caught in the locking hole 13, the detached energizing member 20 Separation is made simply by pushing the locking piece 31 of the finger member 30 in the locking hole 23 of).

Look at the detailed configuration of the present invention assembled as described.

That is, as shown in Figure 6 of the accompanying drawings, the engaging piece 21 of the energizing member 20 is caught in the engaging hole 13 of the terminal body 10, and as shown in the accompanying drawings Figures 4a and 4b The catching piece 31 of the member 30 is caught in the catching hole 23 of the energizing member 20. In addition, the protruding piece 32 of the finger member 30 also maintains a state of being pressed by the paper holding member 40 that carries the opening 24 of the energizing member 20.

The twisted pair connection and disconnection action of the present invention made as described above will be described as shown in FIGS. 4A and 4B and FIG. 5.

In the accompanying drawings, Figure 4a is a cross-sectional view before the twisted pair connection of the wire connection terminal of the present invention, Figure 4b is a cross-sectional view of the state holding the holding member for the twisted pair connection of the wire connection terminal of the holding member 30 by pressing the holding member 40 The case where the protrusion 32 is pressed is shown. In this state, since the holding member 40 presses the protrusion piece 32 of the finger member 30, sufficient space is formed in the left and right sides of the protrusion piece 32 of the finger member 30 to insert the stranded wire.

After releasing the holding member 40, the holding member 40 is raised by the elasticity of the finger member 30, the twisted pair is pushed up with strong elasticity on both sides of the holding member 30 as shown in the accompanying drawings The stranded wire is pushed up slightly to both sides of the opening 24 of the energizing member 20 so as to be strongly connected in a nearly bending shape. At this time, the twisted shape of grounding the stranded wire has a remarkable difference in that the conventional stranded wire connecting structure forms a protrusion at the contact portion of the support member or exhibits a strong connection force that cannot be solved by the corresponding structures of the various elastic means and the energizing member. .

In particular, the present invention adds a structure that keeps the energizing member and the touching member firmly close to each other without being moved in the connection space of the terminal body, so that when the power connection terminals of the conventional similar structure release the holding member, It is to improve the structural problem that had a problem such as easy departure.

In the accompanying drawings, Figure 7 is a perspective view of another embodiment of the wire connection terminal for the light fixture of the present invention, Figure 8 is an exploded perspective view of the wire connection terminal for the lighting fixture of another embodiment of the present invention, Figure 9 is a wire connection for the lighting fixture of another embodiment of the present invention A cross section of the terminal.

According to the drawings, the wire connecting terminal for a lighting device according to another embodiment of the present invention has three connection spaces in the terminal body 10 of the embodiment, and a grounding structure to be described later only in the connection space of the middle part of the connection spaces of the terminal body 10. The case of carrying out is shown.

Therefore, the electric wire connection structure including the energizing member 20, the finger member 30 and the pressure sensing member 40 is equally provided in both connection spaces of the terminal body 10, and further provided with a ground structure described later. In the embodiment, description of the structure overlapping with the above embodiment will be omitted.

The grounding structure of the embodiment according to the present invention FIGS. 7 to 9 has a terminal hole 17, a conduction member 50, and a rudder member 60 which are largely perpendicular to one of the connection spaces of the terminal body 10. ) And a grounding bolt 70.

The conduction member 50 for a grounding structure installed in any one of the connection spaces, forms a space 52 in which the nut 51 is embedded upward, the rear end forms a rectangular through hole 53, the connection space The hole 54 corresponding to the terminal hole 17 is formed.

In addition, the finger member 60 is installed on the energizing member 50, the one end is vertically bent in the energizing member 50 to form a blocking portion 61 to block the connection space, the other end is directed upwards It is bent up to form a contact portion 62 that is contacted on the bottom of the conductive member 50.

The grounding bolt 70 passes through the terminal hole 17 and passes through the tube hole 54 and the nut 51, and is fastened and grounded at a predetermined position where the terminal body is supported at the bottom of the terminal body 10.

The terminal body 10 having the inventive grounding structure as described above has a sense of stability compared to the grounding structure that simply forms a through hole and vertically passes through the grounding bolt of the conventional grounding structure. The reason for this is that the ground bolt 70 is coupled to the nut 51 inserted into the energizing member by screwing, and is subsequently coupled at the lower end of the terminal body through the front end of the connection space where the input of the electric wire is blocked. This is because the tightening force is enhanced as compared with the case without the screw fitting structure.

As such, the present invention solves the simple structure of joining the energizing member and the touch member, and maintains a tight contact even when coupled to the terminal body, and the elastic end of the touch member has a stranded wire between the openings of the conducting member. Since it is pushed up and connected, it shows strong connection force.

Such strong connection force solves the problem of detachment of parts and frequent rest of parts in accordance with the conventional wire connection terminals having a simple assembly structure of the energizing member, the support member and the pressure-sensitive member.

In addition, the present invention improves the disadvantages of the manufacturing process complexity and the increase in manufacturing cost according to the conventionally complicated structure, and the reduction in the traction force or decomposition by maintaining the horizontal connection without considering the characteristics of the stranded wire, This improves the difficult drawbacks of assembly.
