Problems solved by technology

[0010] This shank terminal integrates the shank previously provided separately on each of a pair of terminal terminals, so that it is expected to avoid the drop in operability and achieve miniaturization when it is individually miniaturized, and it is a good form to obtain corresponding effects. However, as mentioned above, the terminal is bent into a U shape to ensure the necessary amount of elastic deformation, but the installation space is slightly increased, and the problem of difficulty in miniaturization cannot be avoided only because of this.

Embodiment 1

[0054] The press-in terminal of this embodiment is basically as figure 1 (a)~(c) and figure 2As shown in (a) to (c), it is composed of the following parts: an insulating housing 2 with a pair of cable insertion holes 1, 1; a terminal 3 arranged in each cable insertion hole 1, 1; Insulating shank portions 5, 5 integrally formed with one operating handle portion 4 in each of the cable insertion holes 1, 1; compression-type spring members for urging the shank portions 5, 5 toward the terminal side 6.

[0055] The aforementioned housing 2 such as figure 1 (a)~(c), figure 2 (a)~(c) and image 3 Shown in (a)~(h), it is to utilize insulating plastic material etc. to be formed into the part that basic shape is cuboid box shape, and the aforementioned pair of cable insertion holes 1, 1 formed on it are in the front upper part of this casing 2. The openings are arranged in a horizontal row, such as figure 2 (a)~(c) and image 3 As shown in (a), (f), and (h), the casing 2 is in...

Embodiment 2

[0080] The example is Image 6 (a) to (c) are examples in which only the configuration of the connection terminal 13 is different from that of the first embodiment, and therefore only the connection terminal 13 will be described.

[0081] The connection terminal 13 is a member made of conductive elastic metal arranged in each cable insertion hole 1 , 1 similarly to the connection terminal 3 of the first embodiment. As shown in the figure, the connection terminal 13 is substantially strip-shaped and is composed of a base portion 13a fixed in a state of abutting against the upper inner wall of the innermost portion of the cable insertion hole 1; The contact portion 13b whose end is extended toward the outer end opening side in the cable insertion hole 1; the lower extension piece 13c extending downward from the inner end of the base portion 13a bent at 90 degrees; the front end of the lower extension piece 13c Further extended narrow terminal tab 13d.

Embodiment 3

[0087] The example is Figure 7 (a) to (c) are examples in which only the configuration of the connection terminal 23 is different from that of the first embodiment, and therefore only the connection terminal 23 will be described.

[0088] The connecting terminal 23 is a member made of conductive elastic metal arranged in each cable insertion hole 1 , 1 like the connecting terminal 3 of the first embodiment. As shown in the figure, the connecting terminal 23 is substantially strip-shaped and is composed of a base portion 23a fixed in a state of abutting against the upper inner wall of the innermost portion of the cable insertion hole 1; The contact portion 23b whose end is extended toward the outer end opening side in the cable insertion hole 1; the lower extension piece 23c extending downward from the inner end of the base portion 23a bent at 90 degrees; the front end of the lower extension piece 23c Further extended narrow terminal tab 23d.

[0089] In addition, the contac...

Abstract

The invention provides a push terminal, of which, the size is reduced by integrating operation levers at every pair of cable insertion holes without sacrificing usability, solving the problem of uncertain connection of cables with small diameter generated when the pair of cables with different diameter from each other is inserted into the cable insertion holes. The push terminal is composed of an insulated housing 2 provided with a pair of cable insertion holes 1, 1; terminals 3 provided with a contact part 3b obliquely extended from a base part 3a toward an opening side and axis center side, arranged in respective cable insertion holes 1, 1; insulated lever base parts 5, 5 arranged to respective cable insertion holes 1, 1, integrally constructed with an operation lever part 4; and compression type coil springs 6 energizing the lever base parts 5, 5, in a manner of enabling a pressing part 5a protruding toward the inner face side of the lever base parts 5, 5 to operate with pressure.

Description

technical field [0001] The present invention relates to a push-in type terminal that electrically and mechanically connects transmission cables of various electric signals and is used for sending and receiving the electric signals. Background technique [0002] In this type of press-fit terminal, for example, it has been proposed that the following parts are provided (Patent Document 1): a housing with a core wire insertion hole and a knob operation portion protrusion hole opened on the front; The part of the front part corresponds to the aforementioned core wire insertion hole and forms the fixed terminal of the core wire insertion hole; the straight-forward operation type knob that can be arranged forward and backward in the housing; the spring that biases the knob toward the front side The front pointed core wire pressing part is protrudingly formed on the front of the knob and closes the core wire insertion hole from the inside of the housing, and is inserted by pressing...
