Abstract
Abstract To inspect the conduction of terminals of a connector having a rear terminal holder (65) without damaging the rear terminal holder, the connector (49) to be tested is first fitted to a connector support member (39) of the terminal conduction test jig (33); and then a test body (41) of the terminal conduction test jig is moved toward the connector support member (39) to first engage the rear terminal holder (65) with the connector housing (55) normally and then inspect conduction of the terminals (35) of the connector (49). That is, a fitted contact projection (85) of the test body (41) is inserted into the connector housing (55) to engage the rear terminal holder with the connector housing normally; and after that the test body (41) is further moved toward the connector support member (39) to bring terminal conduction test pins (89) into contact with the terminals (35) for terminal conduction test.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
236 words
A connector terminal conduction test jig for testing conduction of terminals (35) of a connector (49) having a engaging member (65) engaged with a connector housing (55) thereof, which comprises: a connector support member (39) for supporting the connector (49) to be tested; a test body member (69) disposed movably toward and away from said connector support member and formed with a plurality of through holes (77) each for supporting a terminal conduction test pin (89) movably therein; a contact plate member (73) attached to said test body member and composed of a contact surface (83) and a fitted contact projection (85) formed with a plurality of test pin accommodating holes (87) each communicating with each through hole (77) of said test body member; and when said test body member (69) is moved toward said connector support member (39), the fitted contact projection (85) being first inserted into the connector housing (55) so that the contact surface (83) of said contact plate member (73) urges the connector housing (55) toward said connector support member (39) to correctly engage the engaging member (65) with the connector housing (55), and after that terminal ends (35a) of the terminals (35) arranged in the connector housing being inserted into the test pin accommodating holes (87) of the fitted contact projection (85) into contact with the terminal conduction test pins (89) in the test body member (69) for terminal conduction test.
Claim 2
Dependent Claim
236 words
A connector terminal conduction test jig for testing conduction of terminals (35) of a connector (49) having a engaging member (65) engaged with a connector housing (55) thereof, which comprises: a connector support member (39) for supporting the connector (49) to be tested; a test body member (69) disposed movably toward and away from said connector support member and formed with a plurality of through holes (77) each for supporting a terminal conduction test pin (89) movably therein; a contact plate member (73) attached to said test body member and composed of a contact surface (83) and a fitted contact projection (85) formed with a plurality of test pin accommodating holes (87) each communicating with each through hole (77) of said test body member; and when said test body member (69) is moved toward said connector support member (39), the fitted contact projection (85) being first inserted into the connector housing (55) so that the contact surface (83) of said contact plate member (73) urges the connector housing (55) toward said connector support member (39) to correctly engage the engaging member (65) with the connector housing (55), and after that terminal ends (35a) of the terminals (35) arranged in the connector housing being inserted into the test pin accommodating holes (87) of the fitted contact projection (85) into contact with the terminal conduction test pins (89) in the test body member (69) for terminal conduction test.
Claim 3
Dependent Claim
45 words
The connector terminal conduction test jig of claim 1, wherein the engaging member (65) engaged with the connector housing is a rear terminal holder attached to a rear end of the connector housing (55) for prevention of removal of the terminals from the connector housing.
Claim 4
Dependent Claim
37 words
The connector terminal conduction test jig of claim 1, which further comprises an elastic member (67) attached to said connector support member (39) to allow the engaging member (65) to be engaged correctly with the connector housing.
Claim 5
Dependent Claim
50 words
The connector terminal conduction test jig of claim 1, wherein each end of a plurality of the test pin accommodating holes (87) formed in the fitted contact projection (85) is formed into a conical shape to allow the terminal end (35a) of the terminal (35) to be inserted thereinto smoothly.
Claim 6
Dependent Claim
40 words
The connector terminal conduction test jig of claim 1, wherein each of the terminal conduction test pins (89) movably disposed in the test body member (69) is elastically urged toward said connector support member (39) by a compression spring (81).
Claim 7
Independent Claim
101 words
A method of testing conduction of terminals (35) of a connector (49) having a rear terminal holder (65) engaged with a connector housing (55) thereof by a terminal conduction test jig (33), which comprises the steps of: fitting the connector (49) to be tested to a connector support member (39) of the terminal conduction test jig (33); and moving a test body (41) of the terminal conduction test jig toward the connector support member (39) to first engage the rear terminal holder (65) with the connector housing (55) normally and then inspect conduction of the terminals (35) of the connector (49).
Claim 8
Independent Claim
101 words
A method of testing conduction of terminals (35) of a connector (49) having a rear terminal holder (65) engaged with a connector housing (55) thereof by a terminal conduction test jig (33), which comprises the steps of: fitting the connector (49) to be tested to a connector support member (39) of the terminal conduction test jig (33); and moving a test body (41) of the terminal conduction test jig toward the connector support member (39) to first engage the rear terminal holder (65) with the connector housing (55) normally and then inspect conduction of the terminals (35) of the connector (49).
Claim 9
Dependent Claim
120 words
The method of testing conduction of terminals (35) of claim 6, wherein the step of moving the test body (41) comprises the steps of: inserting a fitted contact projection (85) of the test body (41) into the connector housing (55) so that a contact surface (83) of the test body (41) urges the connector housing (55) toward the connector support member (39) to engage the rear terminal holder with the connector housing normally; and moving the test body (41) further toward the connector support member (39) to bring terminal conduction test pins (89) movably arranged in the test body (41) into contact with terminal ends (35a) of the terminals (35) arranged in the connector housing (55) for terminal conduction test.
