Abstract

A rail terminal assembling structure includes a protection member formed with an assembling passage defined by a contact side section, a connection side section and two lateral sections disposed between the connection side section and the contact side section. The assembling passage has a wire inlet having a first locating section and a second locating section. An end section of a conductive plate extends into the assembling passage and securely attached to the contact side section. A metal leaf spring has a first section, a second section and an elastic bight section connected between the first and second sections. A first located section is disposed on the first section for securely connecting with the first locating section. A second located section is disposed at the tail end of the first section for securely connecting with the second locating section.

First claim

What is claimed is:

1. A rail terminal assembling structure comprising:
a protection member composed of a contact side section, a connection side section opposite to the contact side section and two lateral sections disposed between the connection side section and the contact side section, two lateral stop sections are respectively disposed on the two lateral sections of the protection member near an edge of the second locating section, the contact side section, the connection side section and the lateral sections together defining an assembling passage passing through the protection member, the assembling passage having a wire inlet, the wire inlet having a first locating section and a second locating section disposed at one end of the protection member distal from the first locating section, the second locating section being a stop plate bent from an edge of the connection side section toward the assembling passage, the stop plate having a middle portion formed with an upward protruding elastic tongue section obliquely protruding toward the connection side section, a gap being disposed between the upward protruding elastic tongue section and the connection side section, each of the lateral stop sections being bent toward the assembling passage, the two lateral stop sections respectively abutting against two lateral outer sides of the stop plate;
a conductive plate, an end section of the conductive plate extending into the assembling passage of the protection member and securely attaching to an inner surface of the contact side section; and
a metal leaf spring having a first section, a second section and an elastic bight section connected between the first and second sections, the stop plate serving to stop a tail end of the first section of the metal leaf spring, the tail end of the first section of the metal leaf spring being directly inserted in the gap and being located therein, the metal leaf spring being a substantially U-shaped member, a first located section being disposed on the first section of the metal leaf spring near the elastic bight section, in addition, a second located section being disposed on the first section in a position corresponding to the second locating section for cooperatively and securely connecting with the second locating section, whereby the first section of the metal leaf spring can extend into the assembling passage in attachment to the connection side section with the first located section securely assembled with the first locating section and the second located section securely assembled with the second locating section, the metal leaf spring and the protection member themselves having the ability of securely assembling with each other, the second section of the metal leaf spring extending toward the contact side section to press an end section of the conductive plate that extends into the assembling passage.

2. The rail terminal assembling structure as claimed in claim 1 , wherein the first locating section is lateral notches disposed at a junction between the connection side section and each of the two lateral sections, the first located section being lateral protrusion sections disposed on the metal leaf spring corresponding to the lateral notches.

3. The rail terminal assembling structure as claimed in claim 2 , wherein the second locating section is at least one protruding elastic locating section disposed on the connection side section of the protection member, the second located section being a locating hole formed on the first section of the metal leaf spring corresponding to the elastic locating section.

4. The rail terminal assembling structure as claimed in claim 2 , wherein the lateral stop sections are respectively disposed on an edge of the two lateral sections of the protection member.

5. The rail terminal assembling structure as claimed in claim 2 , wherein the second locating section is a lateral bottom section connected between edges of the two lateral sections, the lateral bottom section being positioned on the same side as the connection side section and lower than the connection side section, whereby a lower gap with a height difference is formed between the lateral bottom section and the connection side section, at least one protruding elastic locating section being disposed on the lateral bottom section, a locating hole being formed on the first section of the metal leaf spring corresponding to the elastic locating section, whereby after the first section is passed through the lower gap, the elastic locating section is inserted in the locating hole so that the first section of the metal leaf spring is securely connected with the connection side section and the lateral bottom section.

6. The rail terminal assembling structure as claimed in claim 2 , wherein the conductive plate is respectively formed with lateral recesses near at least one lateral side of two end sections, the lateral recesses being fittable with a portion of at least one lateral section of the protection member in adjacency to the contact side section and tightly connected therewith, whereby the protection member is located and hindered from moving in an axial direction of the conductive plate.

7. The rail terminal assembling structure as claimed in claim 2 , wherein an end face of the second section of the metal leaf spring is formed with an elastic end section arched and bent toward the contact side section.

8. The rail terminal assembling structure as claimed in claim 7 , wherein the conductive plate has at least two end sections, the end sections being respectively bent to extend in different directions, each end section being attached to a respective protection member, whereby the wire inlet of each of the protection members attached to the conductive plate are correspondingly directed in the different directions of the end sections of the conductive plate.

9. The rail terminal assembling structure as claimed in claim 2 , wherein the conductive plate has at least two end sections, the end sections being respectively bent to extend in different directions, each end section being attached to a respective protection member, whereby the wire inlet of each of the protection members attached to the conductive plate are correspondingly directed in the different directions of the end sections of the conductive plate.

10. The rail terminal assembling structure as claimed in claim 1 , wherein the second locating section is at least one protruding elastic locating section disposed on the connection side section of the protection member, the second located section being a locating hole formed on the first section of the metal leaf spring corresponding to the elastic locating section.

11. The rail terminal assembling structure as claimed in claim 1 , wherein the stop plate is formed with a perforation on one side near the connection side section, the tail end of the first section of the metal leaf spring being formed with an end protrusion section corresponding to the perforation, the end protrusion section being inserted in the perforation and located therein.

12. The rail terminal assembling structure as claimed in claim 1 , wherein the conductive plate is respectively formed with lateral recesses near at least one lateral side of two end sections, the lateral recesses being fittable with a portion of at least one lateral section of the protection member in adjacency to the contact side section and tightly connected therewith, whereby the protection member is located and hindered from moving in an axial direction of the conductive plate.

13. The rail terminal assembling structure as claimed in claim 1 , wherein an end face of the second section of the metal le
