Definitions

  • the present invention relates to an electrical connector and in particular to a structure improvement for connection terminals of a terminal block.
  • a terminal block is an electronic component widely applied to various machines and tools which need electrical connection.
  • the terminal block can be used for the connection with a power cable and a control cable, or used for data transmission line.
  • the terminal in the traditional terminal block is formed by a mutual combination of a body and an elastic plate; the mutual combination is achieved by riveting or snap-in latch. Due to the terminals suffering from the repeated use of connection, the combination effect between the body and the elastic plate is likely to be damaged or the connection could be separated due to insufficient strength of snap-in latch structure. Consequently, the terminals will lose the original functions easily.
  • the inventor pays special attention to research with the application of related theory and tries to improve and overcome the above disadvantages regarding the above related art, which becomes the improvement target of the inventor.
  • the main objective of the present invention is to provide a structure improvement for connection terminals of a terminal block, which can achieve a good combination effect by mutual hooking or mutual resisting between the components.
  • the present invention provides a structure improvement for connection terminals of a terminal block, which comprises a frame body and at least one elastic part.
  • the frame body has a bottom plate and at least one standing plate bending and extending from a side of the bottom plate.
  • the standing plate further extends to form a resisting portion and a first frame curved opposite to the resisting portion.
  • the elastic part has a contact portion, a hook portion further extending from the contact portion, and a second frame curved opposite to the hook portion.
  • the resisting portion passes through the second frame to resist in the second frame.
  • the hook portion passes through the first frame to hook on the first frame.
  • the contact portion is disposed and moved from a side of the first frame to the resisting portion.
  • FIGS. 1 , 2 , and 3 are the perspective exploded view of the first embodiment of the present invention, the perspective assembled view of the first embodiment of the present invention, and the cross-sectional view of the connection terminal disposed in the terminal block in operation according to the first embodiment of the present invention, respectively.
  • the present invention provides a structure improvement for connection terminals of a terminal block, which is disposed in the terminal block 3.
  • the terminal block 3 is provided with a hollow terminal slot 30 therein and a plug hole 31 therein communicating with the terminal slot 30 for the insertion of the connecting wire (not shown) such that after the connection terminals of the terminal block are disposed in the terminal slot 30, an electrical connection of the connection wire can be provided by inserting the connection wire into the plug hole 31.
  • the connection terminals of the terminal block comprise a frame body 1 and at least one elastic part 2.
  • the frame body 1 has a bottom plate 10 and at least one standing plate 11 bending and extending from a side of the bottom plate 10.
  • the frame body 1 has two standing plates 11 which are individually disposed at two sides of the bottom plate 10 to bend and extend; the two sides of the bottom plate 10 are opposite to and separate from each other.
  • Each of the two standing plates 11 further extends to form a resisting portion 110 and a first frame 111 curved opposite to the resisting portion 110.
  • the resisting portion 110 can bend toward outside of the standing plate 11.
  • the first frame 111 can be shaped like a letter of "U” or “L” and comprises a first primary frame edge 112 and at least one first secondary frame edge 113 which extends from the standing plate 11 and connects to the first primary frame edge 112 such that a first opening 114 is formed in the first frame 111.
  • each of standing plates 11 corresponds to an elastic part 2.
  • Each of standing plates 11 has a contact portion 20, a hook portion 210 further extending from the contact portion 20, and a second frame 22 curved opposite to the hook portion 210.
  • the second frame 22 and the contact portion 20 extend in the same direction.
  • the contact portion 20 forms a curved portion 21 which is integrally connected to the hook portion 210 and the second frame 22.
  • the hook portion 210 further can consist of a hook end 211 and an elastic arm 212 and be connected to the contact portion 20 or the curved portion 21 through the elastic arm 212.
  • the second frame 22 can be also shaped like a letter of "U” or “L” and comprises a second primary frame edge 220 and at least one second secondary frame edge 221 which extends from the contact portion 20 or the curved portion 21 to connect to the second primary frame edge 220 such that a second opening 222 is formed in the second frame 22.
  • the contact portion 20 of the elastic part 2 has to be disposed toward the resisting portion 110 from a side of the first frame 111.
  • the hook portion 210 of the elastic part 2 passes through the first opening 114 of the first frame 111 such that the hook portion 210 hooks on the first frame 111. In this way, a good combination effect can be achieved by means of the mutual hooking and mutual resisting.
  • connection terminals of a terminal block of the present invention is obtained.
  • FIG. 4 is a perspective exploded view of the second embodiment of the present invention.
  • a slit 115 can be recessed at the inner edge of the first primary frame edge 112 of the first frame 111 to match with and fix the hook end 211 of the hook portion 210.
  • FIGS. 5 and 6 are the perspective views of the elastic part according to the third and the fourth embodiments of the present invention, respectively.
  • the length of the elastic arm 212 of the hook portion 210 can be zeroed, decreased (shown in FIG. 5 ), or increased (shown in FIG. 6 ) depending on the configuration between the elastic part 2 and the frame body 1.
  • two slots 213 can be individually disposed at two sides of the hook end 211 of the hook portion 210 to match with and further lock the slit 115.
