The invention relates to electric connectors, particularly to an improved terminal block structure.
A terminal block is an electric component used in machines or devices with requirements of connecting electric apparatuses. It can used to connect power cords, control lines or data transmission lines.
Usually, a conventional terminal block is composed of a body and an elastic sheet assembled thereto. The body and the elastic sheet are assembled by riveting or engagement. Besides the elastic sheet or a conductive terminal, a metal cap is usually needed to prevent a wire from laterally escaping from the body when the wire is fixed. Thus, material and assembling costs will be increased. This is an issue to be solved.
An object of the invention is to provide an improved terminal block structure, which can fasten a wire by existing components without an additional cap to save manufacturing costs.
To accomplish the above object, the invention is to provide an improved terminal block structure, which includes an insulative body, a conductive member, an elastic sheet and a pressing member. The insulative body has a receiving room therein and is formed with a pressing hole and a wire hole, which separately communicate with the receiving room. The conductive member is received in the receiving room and has a seat and a contact portion tilted up from the seat. The elastic sheet is received in the receiving room. An end of the elastic sheet is in contact with the conductive member. The pressing member is disposed in the pressing hole and capable of moving toward the receiving room to push another end of the elastic member. The pressing member has a placement slot. Each of two sides of the placement slot having a blocking wall. The wire is inserted into the wire hole to pass through the placement slot and is pushed by the another end of the elastic member to be in contact with the contact portion.
Please refer to
A size of the insulative body 1 can be varied depending upon the number of the wires 5 to be inserted. Also, both the elastic sheet 3 and the pressing sheet 3 can be increased depending upon the number of the wires 5. In the embodiment of the invention, the insulative body 1 is a long flat body and allows the wires 5 to be inserted into a longitudinal side thereof. For the sake of conciseness, only one wire is depicted. The insulative body 1 has a receiving room 10 therein. The receiving room 10 is formed in a side of the insulative body 1. The insulative body 1 is formed with a pressing hole 11 and a wire hole 12. The wire hole 12 is used to be inserted by the wire 5.
Please refer to
The elastic sheet 3 is received in the receiving room 10. An end of the elastic sheet 3 is in contact with the conductive member 2. The pressing member 4 is disposed in the pressing hole 11 and capable of moving toward the receiving room 10 to push another end of the elastic member 3. In this embodiment, the elastic sheet 3 has an elastic portion 30, a first end 31 extending from an end of the elastic portion 30 and a second end 32 extending from another end of the elastic portion 30. The first end 31 is fastened into the material hole 200 of the seat 20 and the second end 32 is fastened with the pressing member 4.
Please further refer to
By the abovementioned structure, the improved terminal block structure of the invention can be obtained.
Accordingly, as shown in
Therefore, in the present invention, after inserting the wire 5, it is restricted in the placement slot 40 by the pressing member 4 so that the wire 5 can be firmly fastened without an additional cap to save manufacturing costs.
It will be appreciated by persons skilled in the art that the above embodiment has been described by way of example only and not in any limitative sense, and that various alterations and modifications are possible without departure from the scope of the invention as defined by the appended claims.
