## Abstract

A terminal module (10) includes an electrical contact member (11) having a coil holding surface (12F) configured to face a contact surface (62F) provided on a mating terminal (61), a conductive obliquely wound coil spring (21) and a holder (31) configured to hold the obliquely wound coil spring (21) by being assembled with the electrical contact member (11). The holder (31) includes a holder body (32) configured to hold the obliquely wound coil spring (21) along the coil holding surface (12F) and having a window portion (35) configured to expose the obliquely wound coil spring (21) toward a side opposite to the coil holding surface (12F), and locking pieces (39) continuous from the holder body (32) and configured to engage the electrical contact member (11).

## Claims

### Claim 1

A terminal module, comprising:
an electrical contact member having a coil holding surface configured to face a contact surface provided on a mating terminal;
a conductive obliquely wound coil spring; and
a holder configured to hold the obliquely wound coil spring by being assembled with the electrical contact member;
the holder including:
a holder body configured to hold the obliquely wound coil spring along the coil holding surface and including an opening configured to expose the obliquely wound coil spring toward a side opposite to the coil holding surface;
an engaging portion continuous from the holder body and configured to engage the electrical contact member; and
the holder body being displaceable in directions toward and away from the coil holding surface.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The terminal module of claim 1, wherein the holder includes a displacement restricting portion configured to restrict a displacement of the holder body in the direction toward the coil holding surface by butting against the coil holding surface.

### Claim 4 (depends on 1, 3)

A connector, comprising:
the terminal module of claim 1 or 3; and
a connector housing configured to hold the terminal module.

### Claim 5 (depends on 4)

The connector of claim 4, wherein:
the engaging portion includes a deflecting piece extending from the holder body and deflectable in a direction intersecting an extending direction from the holder body and a locking projection projecting from the deflecting piece and configured to lock the electrical contact member; and
the connector housing includes a deflection restricting wall configured to restrict the deflection of the deflecting piece in a direction to be disengaged from the electrical contact member by interfering the deflecting piece.
