Abstract

There is disclosed a pin plug comprising a rod electrode and a cylindrical cap electrode encircling coaxially the rod electrode and a base body for supporting the rod electrode and the cap electrode. The base body includes a head section for supporting the bar electrode and a body section providing continuous axial and radial grooves for receiving the connecting cord with an annular space formed therebetween and with a stem portion coupling the head section with the body section.

Claims

1. A pin plug for attachment to the lead wire of a connecting cord comprising a bar electrode and a cap electrode and a base for holding said bar electrode and said cap electrode coaxially and insulatedly from each other and a flexible sleeve for coating said base, said base including a head section for supporting said cap and bar electrodes and a body section provided in its circumference with at least one continuous groove for receiving the lead wires of a connecting cord, said continuous groove comprising at least three tandemly arranged groove portions, at least one of said groove portions extending axially and one of said groove portions extending radially of said base, said axial and radial groove portions alternating with each other, said base being formed with an annular space between said head and body sections for connection of one of said lead wires to said cap electrode and a stem portion coupling said head and body sections, and through which said bar electrode extends for connection of the other lead wire and at least one hole in communication with the last radial groove for passing the lead wire to said stem portion to be connected to the bar electrode.

2. A pin plug as claimed in claim 1, wherein the stem portion is provided with a window to expose the bar electrode for connection with the lead wire derived from the connecting cord.

3. A pin plug as claimed in claim 1, wherein the cap electrode is provided with a recess for receiving a terminal end of the lead wire to be connected therewith.

4. A pin plug as claimed in claim 1, wherein the flexible sleeve is provided in its circumferential wall with an annular ridge which is adapted to be received in the annular space formed between the head section and the body section.

5. A pin plug as claimed in claim 1, wherein the marginal edge portion of the base body is provided with a recess in communication with the last radial groove for receiving another lead wire to be connected to the cap electrode.
