[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pressure contact terminal for connecting a coaxial cable, particularly when assembling a coaxial connector.

[0002]

[Prior Art]

 As a conventional pressure contact terminal, for example, there is a coaxial connector outer conductor connecting tool disclosed in Japanese Utility Model Laid-Open No. 59-86669. FIG. 3 is a front sectional view showing a configuration of a T-branch coaxial connector outer conductor connecting tool, which is an example thereof, and FIG.

The T-branch coaxial connector outer conductor connector includes first and second base bodies 10a and 10b in which accommodation chambers R for accommodating a coaxial cable are formed between the T-branch coaxial connector and the outer conductor connection tools. ing. A first contact body 8a that contacts the outer conductor 6b of the coaxial cable 6 is disposed on the inner surface of the accommodation chamber R of the first substrate 10a, and the accommodation chamber R of the second substrate 10b is arranged. A second contact body 8b that contacts the outer conductor 6b of the coaxial cable 6 is also provided on the inner surface of the inside. Further, the first contact body 8a is engaged between the inner surface of the first base body 10a inside the accommodation chamber R and the coaxial cable 6, and is biased toward the coaxial cable 6 side of the first contact body 8a. A leaf spring 9 is provided.

That is, in such a T-branch coaxial connector outer conductor connector, by tightening the bases 10a and 10b with the bolts 7, the coating 6a of the coaxial cable 6 is removed by the first and second contact bodies 8a and 8b. The outer conductor 6b of the coaxial cable 6 is broken and the first and second contact bodies 8a and 8b are brought into contact with each other.

[0005]

[Problems to be solved by the device]

 In the case of the conventional coaxial connector outer conductor connector, in order to break the coating 6a of the coaxial cable 6, first and second contact bodies 8a and 8b are provided on the inner surfaces of the bases 10a and 10b, and the bolts 7 are used to form the bases 10a and 10b. Since it is tightening, the number of parts is large and assembly is complicated. Another problem is that an assembly tool such as a screwdriver is required due to the structure of tightening the bolt 7.

The present invention has been made in view of the above circumstances, and an object thereof is to provide a press-connecting terminal capable of accurately connecting a coaxial cable with a simple configuration.

[0007]

[Means for Solving the Problems]

 According to the present invention, a coaxial cable having an outer conductor and a coating covering the outer conductor is sandwiched between the outer conductor and a pair of conductive pressure-contact bases which are partially cut to contact the outer conductor. The electrically conductive pressure-welding base includes a pressure-contacting cutting piece for cutting the coating, and a locking portion that engages with each other to lock the pressure-contacting cutting piece from being separated from each other. The pressure-contacting cutting piece has a pointed shape. A pressure contact terminal having a blade extending obliquely so that the coating can be cut obliquely when sandwiching the coaxial cable is obtained.

【Example】

 Hereinafter, the pressure contact terminal of the present invention will be described in detail with reference to examples. FIG. 1 is a perspective view showing the structure of a pressure contact terminal according to an embodiment of the present invention.

As shown in FIG. 1, the press contact terminal includes a pair of conductive press contact bases 1a and 1b. The conductive pressure-contact bases 1a and 1b are composed of square plate-shaped portions 4a and 4b, pressure-contact cut pieces 2a and 2b bent in the same direction from two opposite sides of the plate-shaped portions 4a and 4b, and the remaining two. It has fitting pieces 5a and 5b bent in the same direction from the sides. The conductive pressure-contact bases 1a and 1b are fitted to each other such that one fitting piece 5a is located inside the other fitting piece 5b. The fitting pieces 5a and 5b are provided with locking portions 3a and 3b which engage with each other in the direction in which the plate-shaped portions 4a and 4b are separated from each other. A lance blade or the like is used for the locking portions 3a and 3b. In FIG. 1, for clarity of the structure, the coaxial cable 6 is shown in a state of being cut along the outer surfaces of the press-contacting cut pieces 2a and 2b in the longitudinal direction. The coaxial cable 6 is formed by covering the center conductor 6d with an inner insulator 6c, an outer conductor 6b, and a coating (outer sheath) 6a.

The pressure-contact cutting pieces 2a and 2b have a pointed shape and extend obliquely so that the coating 6a of the coaxial cable 6 and the external conductor 6b can be partially cut in the oblique direction. It has a blade. When the coating 6a and the external conductor 6b are cut, the pressure contact cutting pieces 2a and 2b do not abut each other and maintain a gap, so that the coating 6a and the external conductor 6b are only partially cut and not peeled off. In other words, the press contact cut pieces 2a, 2b are pressed into contact with the coating 6a and the external conductor 6b in a partially embedded state. The conductive pressure-contact bases 1a and 1b in this state receive mutual separation force by the coaxial cable 6, but the fitting state is maintained by mutual engagement of the locking portions 3a and 3b.

FIG. 2 shows the configuration of the pressure contact cut pieces 2a and 2b. Here, a cut object 6e consisting of a partially cut coating 6a and an outer conductor 6b is sandwiched between the press-contact cut pieces 2a, 2b in the vicinity of the tips thereof. 6e shows a pressed state.

In the pressure contact terminal having such a configuration, the cover 6a and the external conductor 6b are partially cut by the pressure contact cut pieces 2a and 2b, and the floating drag force received from the coaxial cable 6 is locked by the locking portions 3a and 3b. Therefore, by simply sandwiching and pressing the coaxial cable 6 between the conductive pressure-contact bases 1a and 1b, the contact between the conductive pressure-contact bases 1a and 1b with respect to the external conductor 6b can be properly achieved. Further, since the pressure contact cutting pieces 2a and 2b have a pointed shape, pressure contact can be performed with a small pressing force.

[0013]

[Effect of the device]

 As described above, according to the present invention, it is possible to obtain a convenient pressure contact terminal capable of accurately connecting a coaxial cable with a simple structure. Since the press-connecting terminal of the present invention can perform press-connecting by sandwiching the coaxial cable between the pair of conductive press-connecting bases and pressing with a small pressing force, an assembly tool such as a screwdriver is not required for connecting the coaxial cable. Thereby, the workability for connecting the coaxial cable can be improved. In addition, the pressure contact terminal of the present invention has the advantage that it can be provided at a low price because it has a small number of parts.
