The present invention relates generally to a rail terminal assembling structure, and more particularly to a rail terminal assembling structure, which is convenient to assemble and can be securely located. In addition, the direction of the wire inlet of the rail terminal assembling structure can be adjusted in accordance with the required plug-in angle of the external conductive wire.
A conventional terminal structure has an insulation case and a metal component or a metal leaf spring enclosed in the insulation case. The metal leaf spring serves to press and electrically connect with a conductive wire plugged into the terminal. The terminals are arranged and latched on a grounding rail (or conductive rail) to establish a common grounding device of an electrical apparatus or a mechanical apparatus for conducting the residual voltage or static charge of the apparatus.
When assembled, the protection member 8 is fitted around the upright arm 72 of the conductive plate 7. At this time, the second side 82 and the subsidiary side 85 are respectively fitted on two lateral sides of the upright arm 72 and the finger section 95 of the metal leaf spring 9 is inserted into the notch 71 of the conductive plate 7. The first section 91 is attached to the inner face of the third side 83. Then, the first section 91 and the third side 83 are connected with each other by means of a welding point 80 (as shown in
However, in practice, the above structure has the following shortcomings:
1. The finger section 95 of the metal leaf spring 9 is inserted into the notch 71 so as to connect and locate the metal leaf spring 9 on the conductive plate 7. Therefore, the upright arm 72 at the end of the conductive plate 7 must extend in a direction substantially in parallel to the first section 91. (In practice, the upright arm 72 is bent to be approximately normal to the conductive plate 7). Only in this case, the simple shoulder section 73 can be used to reasonably restrict the second section 92 (the head end 93) of the metal leaf spring 9 to one-way elastically move toward the conductive plate 7. Under such circumstance, the design of the conductive plate 7 is indirectly affected. That is, the two end sections of the conductive plate 7 must be such structured as to have the bent upright arms 72. This limits the plug-in angle and direction of the external conductive wire inserted into the terminal. The conductive wire must be inserted into the protection member 8 in a direction normal to the conductive plate 7. Moreover, the conductive wire on the outer lateral side of the conductive support A must be first bent upward and then reversely bent downward so that the conductive wire can be plugged into the protection member 8 to connect with the metal leaf spring 9. This not only leads to inconvenience in working (especially the conductive wire with larger diameter is uneasy to bend), but also will occupy more room.
2. The first side 81 of the protection member 8 contacts the outer side of the upright arm 72. The finger section 95 of the metal leaf spring 9 is inserted into the notch 71. The third side 83 is connected with the metal leaf spring 9 so as to connect with the conductive plate 7. Such connection structure fails to make the protection member 8 securely connected with the conductive plate 7 and located. As shown in
It is therefore tried by the applicant to provide a rail terminal assembling structure to solve the above shortcomings of the conventional rail terminal assembling structure.
It is therefore a primary object of the present invention to provide a rail terminal assembling structure, in which the metal leaf spring is directly securely connected on the protection member. Then the protection member is simply connected with one end of the conductive plate. Accordingly, it is no longer necessary to interconnect the conductive plate and the metal leaf spring. In this case, relative to the conductive plate, the protection member can be designed with the characteristic that the conductive plate can be bent by different inclination angles in accordance with different required plug-in angles of the external conductive wire. Therefore, as a whole, the wiring is facilitated and the required peripheral room is reduced.
It is a further object of the present invention to provide the above rail terminal assembling structure, in which one side of a U-shaped metal leaf spring is attached to the inner surface of a preset connection side section of the protection member. In addition, the front and rear sides of the portion of the metal leaf spring in contact with the connection side section are respectively securely connected with the connection side section. The other side of the metal leaf spring has a movable end in abutment with the conductive plate. Accordingly, the protection member, the metal leaf spring and the conductive plate are securely connected with each other without easy detachment.
It is still a further object of the present invention to provide the above rail terminal assembling structure, in which it is unnecessary to additionally securely connect the metal leaf spring and the connection side section of the protection member by means of the welding point or any other fixing member. Therefore, it is very easy to assemble and process the entire rail terminal and the manufacturing cost is effectively lowered.

In the above rail terminal assembling structure, at least one protruding elastic locating section is disposed on the connection side section of the protection member. A locating hole is formed on the first section of the metal leaf spring corresponding to the elastic locating section. The elastic locating section extends into the locating hole, whereby the first section of the metal leaf spring is securely connected with the connection side section of the protection member and located.

The tail end of the first section of the metal leaf spring is formed with an end protrusion section corresponding to the perforation. The end protrusion section is inserted in the perforation and located therein.

A gap is reserved between the upward protruding elastic tongue section and the connection side section. The tail end of the first section of the metal leaf spring is directly inserted in the gap and located therein.

The lateral stop sections are bent toward the assembling passage. The two lateral stop sections respectively abut against two lateral outer sides of the stop plate.

The elastic locating section 121 is a protruding elastic locating tongue section formed by means of punching.
One end of the conductive plate 2 extends into the assembling passage 14 of the protection member 1 and is securely attached to an inner surface of the contact side section 11. In a preferred embodiment, the conductive plate 2 is respectively formed with lateral recesses 22 near two lateral sides of two end sections. The lateral recesses 22 can be fitted with the portions of the two lateral sections 13 of the protection member 1 in adjacency to the contact side section 11 with the conductive plate 2 attached to the inner side of the contact side section 11. Accordingly, the protection member 1 is located and hindered from moving in the axial direction of the conductive plate 2. The conductive plate 2 has an inner face 23 distal from the contact side section 11. In addition, two end sections of the conductive plate 2 are respectively formed with arched edges 21 bent and extending in a direction away from the assembling passage 14.
In practice, the conductive plate 2 not only can be secured by means of fitting the lateral recesses 22 with the protection member 1, but also can be securely connected with the protection member 1 by means of other suitable structures and manners. In this case, the conductive plate 2 can be better multidirectionally located.
The metal leaf spring 3 has a first section 31, a second section 32 and an elastic bight section 33 connected between the first and second sections 31, 32. Accordingly, the metal leaf spring 3 is a substantially U-shaped member. Two first located sections 313 are respectively disposed on two sides of the first section 31 of the metal leaf spring 3 near the middle of the first section 31, (such as outward expanded lateral protrusion sections). The first section 31 is formed with a locating hole 312 corresponding to the elastic locating section 121.
In a preferred embodiment, a second located section 311 (such as an end protrusion section) is disposed at a tail end of the first section 31 of the metal leaf spring 3. An elastic end section 321 is disposed at a tail end of the second section 32. The elastic end section 321 is arched and bent toward the contact side section 11.
When assembled, after the conductive plate 2 is connected with the protection member 1, the metal leaf spring 3 is extended into the assembling passage 14 with the first section 31 attached to the connection side section 12. The second locating section 15 (the stop plate) serves to stop the tail end of the first section 31 of the metal leaf spring 3.

In use, the external conductive wire A extends into the assembling passage 14 from one side near the first locating section 131. At this time, the conductive wire A first pushes the second section 32 of the metal leaf spring 3 to elastically compress and deform the elastic bight section 33. After the conductive wire A passes through the elastic end section 321, under the elastic restoring force of the elastic bight section 33, the elastic end section 321 of the second section 32 cooperates with the inner face 23 of the conductive plate 2 to together hold the conductive wire A and electrically connect therewith. In the case that the conductive wire A is pulled by an external force, the conductive wire A will drive the second section 32 to move in reverse direction. Under such circumstance, the second section 32 will gradually move toward the conductive wire A and fasten the conductive wire A to effectively hinder the conductive wire A from being loosened and extracted out.
In the above structure of this embodiment, the first locating sections 131, the elastic locating section 121 (the elastic locating tongue section) and the perforation 151 of the second locating section 15 are connected with the first located sections 313, the locating hole 312 and the second located section 311.
