JP 2011-86415 A

  In the case of the conventional pair of coaxial electrical connectors, when the first connector 2 is rotated with respect to the second connector 11, the first connector 2 is positioned and held at a plurality of positions. To increase the number, the number of the lock finger pieces 8 is increased. However, if this is done, the rigidity of the locking finger piece 8 will be reduced, the click feeling during positioning will be poor, and there is a possibility that the position to be positioned will be deviated and put in a temporary holding state. For example, when the first connector 2 is rotated due to vibration or the like, there is a risk that inaccurate positioning is performed. If the rigidity of the lock finger piece 8 is increased by shortening the lock finger piece 8 or the like, for example, the spring property of the lock finger piece 8 is deteriorated, and it is difficult to smoothly rotate the first connector 2. Become.

  In addition, since the locking portion, the locking finger piece 8, the engaging portion, the anti-rotation protrusion, and the like are inside the locking member 5 and the connector housing 16, the locking portion becomes the engaging portion. It cannot be visually confirmed whether or not it is locked, and it cannot be confirmed whether or not it is in a state where it is positioned and held.

  The present invention has been made paying attention to such points, and an object of the present invention is to provide a pair of connectors that are positioned and held at a plurality of positions by rotating the other connector with respect to one connector. In the coaxial electrical connector, a component for imparting elasticity along the fitting direction between the two connectors and a component for positioning the other connector in the rotational direction with respect to the one connector are separated. Therefore, the number of positions to be positioned and held can be arbitrarily set, the click feeling when positioning and holding can be increased, accurate positioning and holding can be performed, and the other connector can be smoothly rotated. Furthermore, another object of the present invention is to provide a pair of coaxial electrical connectors that can visually recognize whether or not the other connector is positioned and held.

In order to achieve the above object, a first pair of coaxial electrical connectors of the present invention is a first connector and a second connector that can be freely fitted into or detached from the first connector. With connectors,
The first connector has a first body having an end wall facing the fitting side and having a shielding function, and a portion having a shielding function of the first body via a first insulating member on the first body. A first contact having a contact portion provided in an insulating manner and extending together with the first insulating member from the first main body in the fitting direction; and a cylindrical shape surrounding the first contact and having a circular outer periphery when viewed from the fitting direction. And a first cylinder extending from the end wall facing the fitting side of the first main body to the fitting side,
The second connector is provided with a second main body having a shielding function and the second main body insulated from a portion having the shielding function of the second main body via a second insulating member, together with the second insulating member A second contact having a contact portion extending in the fitting direction from the second main body and having a contact portion which comes into contact with the contact portion of the first contact when at least the first connector and the second connector are completely fitted; A cylindrical shape surrounding the second contact, the inner periphery of which is circular when viewed from the mating direction, and extends from the second body to the mating side to fit between the first connector and the second connector. A second cylinder that fits around the first contact and the second contact and has a shielding function on the outside of the first cylinder at the time,
The inner wall of the first cylindrical body is provided with an inward projection that protrudes inward as viewed from the fitting direction. The second cylindrical body is provided with a fixed end on the second connector and the second cylindrical body. A cantilever-like elastic arm provided with an outward projection extending outward from the fitting direction at the free end, extending to the fitting side inside the two cylinders;
The inward projection and the outward projection are in contact with each other regardless of the rotation of the second cylinder relative to the first cylinder when the first connector and the second connector are fitted. Each has an anti-fitting side surface formed on the slope toward the anti-fitting side toward the base,
The first body, the first insulating member, or the end wall facing the fitting side in the first cylinder, and the fitting in the second cylinder, the second insulating member, or the second body One or more protrusions are provided on the circumference centering on the first contact or the second contact as viewed from the fitting direction in one of the end walls among the end walls facing the side, Two or more recesses are provided on the circumference centered on the first contact or the second contact as viewed from the fitting direction in the end wall, and the two or more recesses have a shape corresponding to the one or more projections. A pair of coaxial electrical connectors provided so that one or more of the recesses are positioned so as to be displaced along the circumference by two or more sets.

  When the second connector is pressed against the first connector in the fitting direction, the two connectors are fitted. That is, the second cylinder is fitted on the outside of the first cylinder so as to be rotatable around the first contact and the second contact. Then, the one or more convex portions are fitted into the one or more concave portions of any one of the sets, thereby positioning the second connector with respect to the first connector in the rotational direction and the first. The second connector is completely fitted into the connector, and the contact portion of the first contact comes into contact with the contact portion of the second contact. Further, when the first connector and the second connector are fitted, the elastic arm bends inward, so that the outward protrusion gets over the inward protrusion and the inward protrusion of the inward protrusion is opposite to the inward protrusion. Entering the mating side, the anti-fitting side surface of the inward projection and the anti-fitting side surface of the outward projection facing each other, so that the complete mating is maintained and is prevented from coming off, and The fitting between the convex portion and the concave portion is maintained, and the position of the second connector in the rotation direction with respect to the first connector is maintained.

  Further, when the second connector is rotated with respect to the first connector from a state in which the second connector is completely fitted to the first connector, the one or more convex portions are moved from the one or more concave portions of the set. When it goes out and rides on a portion adjacent to the circumferential direction of the one or more recesses, the second connector is displaced in the anti-fitting direction with respect to the first connector, and the elastic arm is moved out of the elastic arm. The free end of the elastic arm is bent inward while sliding the anti-fitting side surface of the inward projection to the anti-fitting side surface of the inward projection, whereby the elastic arm is elastically deformed, When one or more convex portions rotate to a position corresponding to one or more concave portions of the other set, the one or more convex portions are fitted into one or more concave portions of the other set by the elastic restoring force of the elastic arm.

Then, the second connector is positioned with respect to the first connector in the rotational direction, and the second connector is completely fitted to the first connector, and the contact portion of the first contact and the second contact are The contact portion comes into contact. In addition, the anti-fitting side surface of the inward projection and the anti-fitting side surface of the outward projection face each other, so that the complete fitting is maintained and the retaining is prevented, and the one or more The fitting between the convex portion and the one or more concave portions is maintained, and the position of the second connector in the rotation direction with respect to the first connector is maintained.

  Then, when the second connector is pulled in the anti-fitting direction with respect to the first connector, the elastic arm causes the surface of the outward projection of the elastic arm to face the anti-fitting side of the inward projection. The elastic arm is elastically deformed by sliding the free end of the elastic arm inwardly while sliding on the surface of the non-fitting side of the elastic arm, and the outward protrusion is moved over the inward protrusion to the inward direction. When the projection comes out to the fitting side of the inward projection, the second connector is detached from the first connector.

  In that case, the elastic arm that provides elasticity along the fitting direction between the first connector and the second connector, and positioning in the rotation direction of the second connector with respect to the first connector The convex portion and the concave portion are not provided integrally, but are provided separately as separate components. Therefore, the elastic coefficient of the elastic arm and the number of the convex portions or the concave portions can be freely set without affecting each other. Accordingly, it is possible to achieve both proper positioning and holding by properly securing a click feeling when positioning and holding, and smooth rotation of the second connector with respect to the first connector. Further, when the one or more convex portions protrude from the one or more concave portions of the set and ride on a portion adjacent to the circumferential direction of the one or more concave portions, the second connector is opposed to the first connector. When the one or more protrusions are displaced in the fitting direction and the one or more protrusions are fitted in one or more of the other recesses, the second connector is displaced in the fitting direction with respect to the first connector. Thus, for example, the gap dimension between the end surface of the first main body facing the fitting side and the end surface of the second cylinder facing the fitting side, etc. If the relative position in the fitting direction of the second connector with respect to the first connector is viewed, it can be visually confirmed whether or not the second connector is positioned and held with respect to the first connector. Further, when the convex portion or the concave portion is provided on the end wall facing the fitting side of the first main body and the end wall facing the fitting side of the second cylindrical body, Since a part and a part of said recessed part are exposed outside, it can be visually recognized also from this surface whether the said 2nd connector is positioned and hold | maintained with respect to the said 1st connector.

The second pair of coaxial electrical connectors according to the present invention is the first pair of coaxial electrical connectors,
A slope that approaches the surface of the end wall is formed in at least one of the convex portion and the concave portion along the circumference toward the end portion.

  According to this configuration, the one or more convex portions protrude from the one or more concave portions of the set and ride on a portion adjacent to the circumferential direction of the one or more concave portions, or the one or more convex portions of the set. The operation of entering the one or more recesses of the other set from a portion adjacent to the circumferential direction of the one or more recesses is smoothly performed.

The third pair of coaxial electrical connectors of the present invention is the first or second pair of coaxial electrical connectors,

This is the same even when a bar antenna whose angle with respect to the fitting direction of the antenna bar is fixed is connected to the second main body. However, according to the universal antenna, the fitting of the antenna bar is further performed. Since the angle with respect to the matching direction becomes free, the antenna bar can be directed in all directions, and the degree of directivity and the selection range are improved.

  In the first pair of coaxial electrical connectors according to the present invention, when the second connector is rotated and held at a plurality of positions with respect to the first connector, the first connector and the second connector are arranged between the first connector and the second connector. Since the elastic arm that provides elasticity along the fitting direction, the convex portion for positioning the second connector relative to the first connector in the rotation direction, and the concave portion are provided separately. The number of positions to be positioned and held can be arbitrarily set, the click feeling when positioning and holding can be increased, accurate positioning and holding can be performed, and the second connector can be smoothly rotated with respect to the first connector. In addition, it is possible to visually check whether or not the second connector is positioned and held with respect to the first connector.

The operation of riding on the portion or the operation of the convex portion entering the concave portion from the portion adjacent to the circumferential direction of the concave portion can be smoothly advanced.

  The third pair of coaxial electrical connectors according to the present invention can obtain the effect obtained by the first or second pair of coaxial electrical connectors, and further, the second connector with respect to the first connector. Instead, a so-called screw-type mating connector can be connected.

  According to the fourth pair of coaxial electrical connectors of the present invention, in addition to obtaining the effect obtained by any one of the first to third coaxial electrical connectors, the first pair of coaxial electrical connectors further includes the first connector with respect to the first connector. The directivity of the universal antenna around the fitting direction can be freely changed by rotating the two connectors.
