Abstract
Abstract A contact pin includes: a pin terminal secured to a stationary base art by press-fitting a press-fitted part into the stationary base part, the pin terminal projecting from the stationary base part and being joined to the board; a contact part inserted into a contact pin through-hole of a movable lock part so that a plug pin terminal is fitted into the contact part; and an auxiliary plate 6 reinforcing the press-fitted part, engaged with the movable lock part and transmitting a force caused by a movement of the movable lock part to the press-fitted part. A connector constructed in the described manner includes a plurality of above-mentioned contact pins.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
190 words
A method of forming a connector by assembling a plurality of contact pin composites, each including a pin terminal to be joined to a board and a contact part for receiving an external electrode terminal, comprising the steps of: providing a stationary base part having a plurality of holes for receiving the pin terminals of the respective contact pin composites; providing a movable lock part having a plurality of holes aligned with the respective pin terminal-receiving holes of said stationary base part for receiving the contact parts of the respective contact pin composites; providing each said contact part at the end thereof with a frangible assembly-aiding part; inserting the pin terminal of each composite into a cooperating hole in said stationary base part; locating the ends of said contact parts containing said assembly aiding part in the contact pin through-holes in said movable locking part; moving said movable locking part with respect to said stationary base part to forcibly insert said assembly-aiding part and said contact part into each of said plurality of contact pin through-holes while detaching said assembly-aiding part from said composite to form a contact pin thereby.
Claim 2
Independent Claim
190 words
A method of forming a connector by assembling a plurality of contact pin composites, each including a pin terminal to be joined to a board and a contact part for receiving an external electrode terminal, comprising the steps of: providing a stationary base part having a plurality of holes for receiving the pin terminals of the respective contact pin composites; providing a movable lock part having a plurality of holes aligned with the respective pin terminal-receiving holes of said stationary base part for receiving the contact parts of the respective contact pin composites; providing each said contact part at the end thereof with a frangible assembly-aiding part; inserting the pin terminal of each composite into a cooperating hole in said stationary base part; locating the ends of said contact parts containing said assembly aiding part in the contact pin through-holes in said movable locking part; moving said movable locking part with respect to said stationary base part to forcibly insert said assembly-aiding part and said contact part into each of said plurality of contact pin through-holes while detaching said assembly-aiding part from said composite to form a contact pin thereby.
Claim 3
Dependent Claim
50 words
The method of assembling a connector as claimed in claim 1 wherein said plurality of pin terminals to be joined to the board are press-fitted into said plurality of pin terminal through-holes provided in said stationary base part with a force caused by a movement of said movable lock part.
Claim 4
Dependent Claim
92 words
The method of forming a connector as claimed in claim 1, including the step of forming said contact pin through-holes with a narrowed part and said assembly-aiding part with a notch part near the end of said contact part, and removing said assembly-aiding part by inserting said assembly-aiding part, together with said contact part, with a force into the narrowed part at each of said plurality of contact pin through-holes whereby said notch part is broken with a force exerted by said narrowed part which is in contact with said notch part.
Claim 5
Dependent Claim
50 words
The method of assembling a connector as claimed in claim 3, wherein said plurality of pin terminals to be joined to the board are press-fitted into said plurality of pin terminal through-holes provided in said stationary base part with a force caused by a movement of said movable lock part.
