  • the present invention relates to a connector for a terminal block connecting a pair of wires electrically together.
  • Each connector includes an individual conducting pipe mounted in an insulted housing and be capable of adjoining at least two wires.
  • the conducting pipe positioned in the insulted housing is entirely made of metal or alloy, such as copper, to ensure the best possible electrical conduction.
  • a wire can be inserted into the end of the opening of the conducting pipe and be squeezed firmly onto the inner sidewall of the conducting pipe to provide electrical conductivity between pairs of wires or cables adjoined via the conducting pipe.
  • making a conducting pipe entirely of copper via machining processes becomes expensive.
  • the existing structure of the connector for terminal block is improved.
  • a connector for terminal blocks as follows: a conducting pipe made of steel including a hollow inner space is mounted in a cylindrical connector body, a conduction plate made of phosphor bronze is clad onto the inner surface of the conducting pipe and the said conducting plate includes a concaved surface having a length substantially the same as that of said conducting pipe along the longitudinal direction thereof. Therefore, the conducting pipe can be made of structurally strong and yet cheap metallic or alloy material, such as iron, and the inner surface of the conducting pipe for wire contacting includes an inner lining brass conduction plate that is capable of saving the more expensive brass material to achieve the characteristic of optimized price-performance.
  • the brass conduction plate and the inner surface of the conducting pipe are stamping-riveted, that is, the conduction plate and the inner surface of the conducting pipe are detached, and are only riveted together in a press-form machining procedure.
  • the brass conduction plate is not rigidly fastened or securely attached on the inner surface of the conducting pipe and is of low conductive reliability, furthermore, it is hard to practice by the technological process of die punching and needs to spend higher costs.
  • the wires in the above structure of the connector are squeezed firmly onto the inner sidewall of the conducting pipe by bolt tips directly, so it is easy to destroy the wires, especially to the multi-core wires.
  • the contract area between the wire and the inner wall of the conducting pipe is small and limited so as to weak the capability of electrical conduction of the said connector. Therefore, the conductive structure of a connector for a terminal block needs to be improved further to resolve the existed problems in the above mentioned patent and to achieve a more optimized performance both in structure and costs.
  • the connector for a terminal block of the present invention comprises:
  • the said metal plate including its two squeezing feet can be entirely mounted inside the longitudinal hole of said conducting pipe, while considering stably fixing the metal plate to the conducting pipe, said conducting pipe is formed by an integrative sheet metal being curled to a D-shape cylindrical body which includes a plat portion where the two ends of the sheet metal comprising a first end portion and a second end portion overlapped one on top of the other, and the first said end portion includes a protruding part, the second end portion includes a corresponding slot receiving said protruding part, furthermore, the middle portion of said metal plate is mounted between said first bended portion and said second bended portion.
  • a longitudinal conducting copper layer in contact with said inserted wire is embedded on the inner sidewall of said conducting pipe, and the surface of the copper layer becomes a part of the inner surface of the sidewall of said conducting pipe, the material of the conducting pipe is a kind of metal whose capability of electrical conduction is weaker than copper, and corresponding wire is squeezed on said conducting copper layer by said bolt.
  • the entire conducting pipe made of the cheap sheet metal, such as iron, and can be produced via machining processes by punching directly.
  • the inner sidewall of the conducting pipe having a copper layer for electrical conducting makes the intensity of the conducting portion higher, the costs of the conducting pipe lower and the manufacture of the connector easier.
  • a longitudinal metal plate is mounted in the sidewall of said conducting pipe to form a conducting route directly for the pair of the adjoined wires inserted into the hole of said conducting pipe and to enhance the electrical conduction. Furthermore, the wire pressed between the squeezing foot and the copper layer is fixed indirectly by the end potion of said bolt to protect the exposed conductive ends of said wires as well as to expand the contact area between said wires and said copper layer.
  • FIGS. 1 ⁇ 4 show the first preferred embodiment of the present invention.
  • the connector for a terminal block includes two electrical insulated housings 1 in parallel which are in the form of structurally connected by a common traverse connecting bar 14, and each insulated housing 1 is capable of adjoining at least two wires 6.
  • the individual insulated housing 1 contains a rectangular opening 13 in which mounts an iron conducting pipe 2 with a longitudinal hole 21, and a copper layer 4 in contact with said wires is embedded in the inner sidewall of the conducting pipe 2, which is in a length along the longitudinal direction of the conducting pipe 2 and the surface of the copper layer 4 becomes a part of the inner surface of the sidewall of said conducting pipe 2 .
  • a pair of first screw holes 11 that are suit for bolts extending through the opening 13 are symmetrically set on the sidewall of each insulated housing 1, and a screw well 12 is provided on its corresponding first screw 11 hole for which making the bolts 3 sink into, two corresponding second screw holes 22 which are opposite to the first screw hole 11 are opened through the entire thickness of the sidewall of the conducting pipe's cylindrical body, each second screw hole 22 includes a protruding platform 23 and wires 6 can be inserted into the longitudinal hole 21 of the conducting pipe 2.
  • the wire 6 inserted into the longitudinal hole 21 of the conducting pipe 2 can be squeezed firmly onto the copper layer 4 of the inner sidewall of the conducting pipe 2 under the pressure of a bolt 3 screwed into the first screw hole 11 as well as its corresponding second screw hole 22.
  • the said conducting pipe 2 is formed by an integrative sheet metal being curled to a D-shape cylindrical body with two end portions 25, 26 of the sheet metal being bended oppositely.
  • the drawings of FIG 2 depicts the conducting pipe 2 with a letter D end shape forming a plat portion where the two ends of the sheet metal comprising a first end portion 25 and a second end portion 26 overlapped one on top of the other.
  • the first end portion 25 has two protruding part 251 and the second end portion 26 includes two corresponding slots 261 receiving said protruding part 251, and the protruding part 251 can be inserted into the slots 261 to make sure the two ends of the roll-formed sheet metal overlapped connection and fastened to each other.
  • the conducting pipe 2 also includes an end shape in conformity with the curved segment of the letter D end shape and the wire 6 is inserted into the longitudinal hole 21 of the conducting pipe 2 directly next to the curved sidewall 24.
  • the entire conducting pipe 2 is made of iron and a copper layer 4 is embedded into the sheet material of the curved sidewall 24 of the conducting pipe 2 by means of strong force, instead of the original press-formed conduction plate, to make sure the copper material compounded within the sheet material.
  • the wires 6 to be electrically connected for either power or signal relay purposes are each inserted into the longitudinal hole 21 of the conducting pipe 2 from its corresponding end and can be firmly squeezed between the bolt tip and the concaved surface of the copper layer 4 so as to ensure the electrical conduction between the two adjoined wires 6.
  • a wire end plate 5 can be formed from the middle portion of the sidewall of the conducting pipe 2 via punching through the sidewall of the conducting pipe 2 and bending inwardly toward the longitudinal hole 21 of the conducting pipe 2, as show in FIG 2 .
  • Said connector for a terminal block can also include only a single electrical insulated housing or include a plurality of electrical insulated housings connected in parallel.
  • FIGS.5 ⁇ 9 show the second preferred embodiment of the present invention.
  • a longitudinal metal plate 7 made of phosphor bronze material is mounted along with the sidewall of said conducting pipe 2 in order to prevent the bolt tip directly pressing onto the wire 6 so as to destroy the wire (especially to multi-core wire) and it also reduces the sliding friction and improves the reliability of electrical conduction.
  • the metal plate 7 includes two ends, and each end of said metal plate 7 extends outside said conducting pipe 2 and then bends inward into the longitudinal hole 21 of the conducting pipe 2 forming a squeezing foot 71, as shown in FIG 6 .
