## Abstract

A contact spring holding jig for grease application includes a spring placement portion on which a connector terminal contact spring is to be placed, and a spring position restricting wall. The connector terminal contact spring includes a plurality of spring pieces and a connecting portion positioning at an end portion of the connector terminal contact spring. The plurality of spring pieces include a gap with adjacent spring pieces are connected to be arranged side by side by the connecting portion. The connector terminal contact spring is placed with the connecting portion facing downward, on the spring placement portion.

## Claims

### Claim 1

A contact spring holding jig configured to receive a connector terminal contact spring to facilitate grease application comprising:
a spring placement portion on which the connector terminal contact spring is to be placed; and
a spring position restricting wall,
wherein the connector terminal contact spring includes a plurality of spring pieces and a connecting portion that has two end surfaces, the connecting portion extends along a circumference of a circle such that the connecting portion extends in a circumferential direction from one of the end surfaces to the other of the end surfaces,
wherein the connecting portion is formed in a circular arc shape,
wherein a first gap exists between adjacent pieces of the plurality of spring pieces, and the plurality of spring pieces are connected to be arranged side by side by the connecting portion,
wherein the connector terminal contact spring is placed with the connecting portion facing downward, on the spring placement portion,
wherein the spring position restricting wall directly extends from the spring placement portion and is disposed in a second gap which is formed between the two end surfaces of the connecting portion in the circumferential direction so as to restrict the position of the connector terminal contact spring in the circumferential direction on the spring placement portion, when the connector terminal contact spring is placed on the spring placement portion,
wherein the spring placement portion is formed in an arc shape corresponding to the connector terminal contact spring, and
wherein the spring position restricting wall is erected on the spring placement portion and disposed along an inner side and an outer side of the connecting portion, and includes an inner wall part and an outer wall part restricting a position of the connector terminal contact spring on the spring placement portion, and wherein the inner wall part and the outer wall part are arranged on the spring placement portion so as to sandwich the connecting portion between the inner wall part and the outer wall part.

### Claim 2 (depends on 1)

The contact spring holding jig for grease application according to claim 1,
wherein the spring position restricting wall is erected on the spring placement portion and disposed in the second gap so as to restrict the position of the connector terminal contact spring from being moved in the direction in which the plurality of spring pieces are arranged on the spring placement portion, when the connector terminal contact spring is placed on the spring placement portion.

### Claim 3 (depends on 1)

The contact spring jig for grease application according to claim 1,
wherein the adjacent pieces are spaced apart from each other by the first gap around a periphery of the connector terminal contact spring.

### Claim 4 (depends on 1)

The contact spring holding jig for grease application according to claim 1,
wherein the circumferential direction is a direction in which the plurality of spring pieces are arranged.
