Description

Optical connector cleaning tool Technical Field The present invention relates to an optical connector cleaning tool for cleaning a connection end surface of an optical connector. For the specification country which acknowledges the introduction based on the reference of the literature, the contents described in japanese patent application No. 2023-214989 of the japanese application on 12/20 of 2023 are incorporated by reference into the present specification as part of the description of the present specification. Background A cleaning mechanism is known in which a cleaning rod in contact with a connection end surface of an optical connector is rotated by a motor to remove an attached matter from the connection end surface (for example, refer to patent document 1). In this cleaning mechanism, the power supply to the motor is turned on/off by sliding a shaft to which a fitting fitted in the optical connector housing is fixed, relative to a collar (collar) fixed to a driving unit provided with the motor. Patent document 1 Japanese patent laid-open No. 2002-277681 In the cleaning mechanism described above, static electricity may be generated in a sliding portion where the shaft slides with respect to the collar, and the shaft may be charged. On the other hand, in an electrostatic management area (EPA: ESD Protected Area) such as a manufacturing process of an electrically sensitive electronic component such as a semiconductor device, it is necessary to rapidly diffuse electrostatic discharge (ESD: electro-STATIC DISCHARGE). Therefore, the cleaning mechanism described above may not be used in the static electricity management area. Disclosure of Invention The invention provides an optical connector cleaning tool capable of rapidly diffusing static electricity generated by sliding of constituent members. [1] An optical connector cleaning tool according to embodiment 1 of the present invention is an optical connector cleaning tool for cleaning a connection end surface of an optical connector, comprising a cleaning shaft around which a cleaning body is hung, and a cleaning head provided at a distal end thereof with a pressing surface for pressing the cleaning body against the connection end surface, a tubular member housing the cleaning shaft, and a housing in which a proximal end portion of the tubular member is housed so that the tubular member can move relative to each other, wherein the tubular member and the housing have electrical conductivity, and wherein the tubular member or the housing has an elastic deformation portion that contacts the housing or the tubular member and presses the housing or the tubular member, and wherein the tubular member and the housing are electrically connected via the elastic deformation portion. [2] In the optical connector cleaning tool according to aspect 1, the elastic deformation portion includes a first leaf spring provided in the tubular member, and the first leaf spring contacts an inner surface of the housing and presses the inner surface outward. [3] In the optical connector cleaning tool according to aspect 1 or 2, the elastically deforming portion includes a second leaf spring provided in the housing, and the second leaf spring contacts an outer surface of the tubular member and presses the outer surface inward. [4] The aspect 4 of the present invention may be the optical connector cleaning tool according to any one of aspects 1 to 3, wherein a pressing force F a for pressing the elastic deformation portion of the housing or the tubular member satisfies the following expression (1). 0.5[N]<Fa<12[N] ... (1) [5] The aspect 5 of the present invention may be the optical connector cleaning tool according to any one of aspects 1 to 4, wherein the housing includes a holding portion for holding an operator who operates the optical connector cleaning tool. [6] The invention according to claim 6 is the optical connector cleaning tool according to any one of claims 1 to 5, wherein the tubular member and the housing are made of a conductive resin material. [7] The invention according to claim 7 is the optical connector cleaning tool according to any one of claims 1 to 6, wherein the optical connector cleaning tool includes a supply/recovery mechanism that supplies the cleaning element to the pressing surface of the cleaning head and recovers the cleaning element from the pressing surface in accordance with the relative movement of the cylindrical member with respect to the housing. In the present invention, the tubular member and the housing have conductivity, and the tubular member or the housing has an elastic deformation portion which contacts the housing or the tubular member and presses the housing or the tubular member, and the tubular member and the housing are electrically connected via the elastic deformation portion. Therefore, static electricity generated in the tubular member due to sliding with the housing can be rapidly diffused through the housing. Drawings Fig. 1
