A device-side terminal group including the second predetermined number of device-side signal terminals, and the power supply-side signal terminal is connected to the electrical device through a device-side signal transmission member group connected to the device-side signal terminal. A power supply side signal transmission member group that transmits electrical signals is connected, and each power supply side signal terminal and each device side signal terminal are between the power supply side signal terminals and between the device side signal terminals, A terminal having compatibility that can be used to transmit different types of electrical signals between the power supply side signal transmission member group and the electrical device, or to transmit the electrical signals to different electrical devices, The power supply side connector is the connection A pair of inclined guide portions spaced apart in a first orthogonal direction orthogonal to the direction, and spaced apart in the first orthogonal direction and positioned between the pair of inclined guide portions in the first orthogonal direction. A pair of concave guide portions, wherein the device-side connector is spaced apart in the first orthogonal direction and the pair of power supply-side terminals and the device-side terminal groups can be contacted and separated. A pair of convex guide portions that are fitted with the concave guide portions, and each of the inclined guide portions is configured to move the device-side connector in the connection direction with respect to the power supply side connector. And the contact in the connection direction, the device-side connector is moved in the first orthogonal direction, and has an inclined surface for guiding the pair of convex guide portions to the pair of concave guide portions. The concave guide portion and the convex guide portion are connected to the connection direction and the first orthogonal direction. The power supply side terminal group and the device side terminal group are separated from each other in the connection direction and are engaged in the first orthogonal direction while extending in parallel to a second orthogonal direction orthogonal to the direction. By fitting, the apparatus-side connector is guided in the connection direction, and the second orthogonal direction width of the concave guide portion is larger than the second orthogonal direction width of the convex guide portion, and thus the above-described problem Is a solution.

  According to a second aspect of the invention, in addition to the configuration of the first aspect of the invention, the power feeding side connectors are spaced apart in the second orthogonal direction and tilted in directions closer to each other as they go in the connection direction. A pair of power supply-side inclined portions, the device-side connector is spaced apart in the second orthogonal direction and has a pair of device-side inclined portions that are inclined toward each other toward the connection direction; The pair of device-side inclined portions are in contact with the pair of power supply-side inclined portions in the second orthogonal direction, so that the device-side connector occupies the power supply-side connector in the second orthogonal direction. The above-described problem is solved by defining the allowable range of the position.

  According to a third aspect of the present invention, in addition to the configuration of the first or second aspect of the invention, different electric devices are fed from the power feeding member through a common power feeding side power supply terminal group and the device side power supply terminal group. The power supply side signal terminals and the device side signal terminals can be used to transmit the electrical signals to the different electrical devices between the power supply side signal terminals and between the device side signal terminals. The above-described problems are solved by using a terminal having such compatibility.

  According to a fourth aspect of the present invention, in addition to the configuration of any one of the first to third aspects, the power feeding side connector is attached to the outer surface of the power feeding side structure on which the power feeding member is installed. The power supply side terminal holding portion for holding the power supply side terminal group, and the device side connector has a device side terminal holding portion for holding the device side terminal group, and in the connected state, the power supply side The side terminal holding part and the device side terminal holding part are in a position where they do not protrude from the outer surface in the separation direction, thereby solving the above-mentioned problems.

  According to the connector device of the present invention according to claim 1, each power supply side signal terminal and each device side signal terminal transmits only a specific electrical signal, and only transmits a specific electrical signal to a specific electrical device. Unlike a type signal terminal, it is a general-purpose type signal terminal capable of transmitting an arbitrary electric signal or an electric signal to an arbitrary electric device. For this reason, it is possible to arbitrarily select and use a pair of a power supply side signal terminal and a device side signal terminal in the power supply side connector and the device side connector regardless of the type of electrical signal or the type of electrical equipment. The degree of freedom in selecting the signal terminals is increased, the convenience of the connector device including the power supply terminal group and the signal terminal group can be improved, and the cost of the connector device can be further reduced.

  Further, when both connectors are connected, the position of the device side connector relative to the power supply side connector is displaced in the first orthogonal direction so that the connection between the power supply side terminal group and the device side terminal group becomes impossible. In the case where this occurs, in the process in which the device-side connector is brought closer to the power-feeding-side connector in the connection direction, one of the pair of convex guide portions is opposed in the connection direction among the pair of inclined guide portions. The pair of convex guide portions and the pair of concave guide portions are fitted to each other and guided to the inclined surface of the inclined guide portion, so that the power supply side terminal group and the device side terminal group can be contacted and separated. As described above, the device-side connector is positioned in the first orthogonal direction with respect to the power supply-side connector, and thereafter, both connectors are connected in a fitted state of the pair of convex guide portions and the pair of concave guide portions. Thereby, the positional deviation of the device-side connector with respect to the power supply-side connector in the first orthogonal direction is eliminated by the pair of inclined guide portions, and both the connectors can be easily connected.

In addition, since the power supply side terminal group and the device side terminal group do not contact each other until the positional deviation of the device side connector in the first orthogonal direction is eliminated, the terminal group of either the power supply side terminal group or the device side terminal group is Even when protruding in the connecting direction or the separating direction, it is possible to prevent the power supply terminal or the signal terminal from being damaged due to the movement of the device-side connector in the first orthogonal direction.
In addition, each concave guide portion that is a structure (hereinafter referred to as a “positional deviation allowing structure”) for enabling the connection state of both connectors while allowing a positional deviation in the second orthogonal direction with respect to the power supply side connector, and Since each convex guide part has the second orthogonal direction width of each convex guide part smaller than the second orthogonal direction width of each concave guide part, the device-side connector can be reduced in size and weight.
Further, since the positional deviation tolerance structure is each concave guide part and each convex guide part, the structure for allowing the positional deviation in the second orthogonal direction is simplified, so the device-side connector is small and lightweight. And the cost of the connector device can be reduced.

As described above, the power supply side terminal group 130 and the device side terminal group 160 are arranged in the holders 110 and 150 so as to form a plurality of terminal rows in the vertical direction, thereby minimizing the connectors 101 and 102 in the lateral direction. The number of power supply side terminals 136 and the number of device side terminals 166 can be increased.

  Referring to FIG. 2, the minimum interval S1 between the power supply terminal groups 131 and 161 and the signal terminals 134 and 164 in the horizontal direction is equal to the power supply side signal terminals 134 and the device side signals arranged at equal intervals in the horizontal direction. It is larger than the minimum interval S2 between the terminals 164. As a result, when the power supply terminal groups 131 and 161 are energized, it is possible to reduce noise with respect to electrical signals passing through the signal terminals 134 and 164 adjacent to the power supply terminal groups 131 and 161 in the lateral direction. It is possible to prevent erroneous assembly in which the device-side connector 102 is assembled with respect to 101 in the direction opposite to the normal direction in the lateral direction.

Referring to FIGS. 1, 4, and 5, each concave guide portion 117 opened in the facing surface 113 a forms a rectangular parallelepiped fitting space 117 c that is long in the vertical direction and 2 in the vertical direction. It is formed to extend in parallel in the vertical direction over a formation range A12 that is larger than the arrangement range A11 (see FIG. 4) of the slits 118 in the row. The convex guide portion 157 has a rectangular parallelepiped shape that is long in the vertical direction, and is formed to extend in the vertical direction over the formation range A22 that is larger than the arrangement range A21 of the two rows of contact portions 167 in the vertical direction. Yes. The vertical width W12 of the concave guide portion 117 is larger than the vertical width W22 of the convex guide portion 157.
Referring also to FIG. 2, the protruding amount of the convex guide portion 157 in the connecting direction is larger than the protruding amount of the contact portion 167 in the connecting direction with respect to the facing surface 153 a.

The lateral width W11 of the fitting space 117c is larger than the lateral width W21 of the convex guide portion 157 by a predetermined width. The predetermined width is a size for positioning the power supply side terminal group 130 and the device side terminal group 160 at the alignment position by fitting the pair of concave guide portions 117 and the pair of convex guide portions 157.
Here, the alignment positions of both terminal groups 130 and 160 are positions where the power supply side terminal group 130 and the device side terminal group 160 can come into contact with each other, that is, between the power supply side terminal 136 and the device side terminal 166 that are in contact with and away from each other. The pair is a position aligned in the connection direction and opposed in the connection direction.
In this way, the pair of convex guide portions 157 and the pair of concave guide portions 117 are arranged so that both the terminal groups 130 and 160 can be brought into contact with and separated from the power supply side connector 101, and thus the wall. 10 is a positioning unit for setting the position of the floor head base 20 with respect to 10 in the horizontal direction.

Referring to FIG. 2, the inclined surface 115 a has a convex guide portion 157 (for example, a left convex guide indicated by a two-dot chain line in FIG. 2) in the process of bringing the floor head 20 close to the wall 10. Part 157) in the connecting direction in the connecting direction, the floor head base 20 is moved in the lateral direction (in the example shown in FIG. 2, to the right indicated by an arrow), and a pair of convex guide parts 157 Are guided to the pair of concave guide portions 117.
And the concave guide part 117 and the convex guide part 157 are fitted while engaging in the lateral direction in a state where the power supply side terminal group 130 and the device side terminal group 160 are separated in the connection direction, The floor head 20 approaching the wall 10 is guided substantially parallel to the connection direction. For this reason, the equipment side terminal group 160 is further moved in the connection direction with respect to the wall 10 from the state in which the equipment side terminal group 160 is separated from the opposing surface 113a and the power supply side terminal group 130 in the connection direction. The contact portion 167 of the terminal 166 is inserted into the slit 118 and further into the contact portion 137 of each power supply side terminal 136, and the connection is completed as shown in FIG. In this connection completion state, the attachment portions 112 and 152 may be in surface contact with each other in the connection direction, and each inclined surface 115a and each first connection portion 155 may be in surface contact.

Next, operations and effects of the embodiment configured as described above will be described.
The connector device 100 is fixed to the power supply side connector 101 fixed to the wall 10 on which the power supply conducting wire group 41 is installed, and the floor head base 20 on which a plurality of electric devices 70 to be fed through the power supply conducting wire group 41 are installed. Each of the electrical devices 70 includes a device-side connector 102, and each of the electrical devices 70 is in contact with each other in a connected state of both connectors 101, 102. Power is supplied from the power supply conductor group 41 through the.
Thereby, the power supply from the power supply lead wire group 41 to the electric device 70 is performed by the direct connection between the power supply side power supply terminal group 131 and the device side power supply terminal group 161 by connecting both the connectors 101 and 102. For this reason, between the wall 10 and the floor head stand 20, power can be supplied from the power supply conductor group 41 to the electric device 70 without using a power supply cable.

Each power supply side signal terminal 134 and each device side signal terminal 164 are of different types between the power supply side signal terminals 134 and between the device side signal terminals 164 and between the signal conductor group 42 and the electric device 70. It is a compatible terminal that can be used for transmission of electrical signals and transmission of electrical signals to different electrical devices 70.
Thereby, the transmission of the electric signal between the signal conductor group 42 and the electric device 70 is performed directly between the power supply side signal terminal 134 and the device side signal terminal 164 by the connection of the power supply side connector 101 and the device side connector 102. Done by connection. For this reason, since a signal cable (for example, a LAN cable) is not used between the wall 10 and the floor head base 20 in addition to the power feeding cable, transmission of electric signals and power feeding between the wall 10 and the floor head base 20 are performed. Cable-less.
In addition, each power supply side signal terminal 134 and each device side signal terminal 164 transmit only a specific electrical signal, and different from a dedicated signal terminal that transmits an electrical signal only to a specific electrical device 70, any arbitrary signal terminal. This is a general-purpose signal terminal capable of transmitting an electric signal or an electric signal to an arbitrary electric device 70. For this reason, regardless of the type of electrical signal or the type of electrical device 70, a pair of the power supply side signal terminal 134 and the device side signal terminal 164 is arbitrarily selected and used in the power supply side connector 101 and the device side connector 102. Therefore, the degree of freedom in selecting the signal terminals 134 and 164 is increased, and the convenience of the connector device 100 including the power supply terminal groups 131 and 161 and the signal terminal groups 132 and 162 can be improved. The cost of the connector device 100 can be reduced.

  Furthermore, since the space between the wall 10 and the floor head base 20 is made cableless, when a patient moves to another room, there is a power supply cable or a signal cable between the wall 10 and the floor head base 20. In comparison, the movement of the floor head base 20 can be facilitated, and furthermore, there is no risk of infection through the cable when the power supply cable or the signal cable is moved together with the floor head base 20 to another hospital room. Infection prevention due to movement of the head 20 can be ensured and facilitated.

The wall 10 has a wall surface 11 facing the floor head base 20 in the connection direction in the connected state, and in the connected state of both the connectors 101 and 102, the power supply side terminal holding portion 119 and the device side terminal holding portion 153 are in the separating direction. In the position which does not protrude from the wall surface 11.
Thereby, in the connection state of the electric power feeding side connector 101 and the apparatus side connector 102, since the floor head stand 20 is arrange | positioned close to the wall 10 in a connection direction, the floor head stand 20 can be arrange | positioned compactly in a hospital room. .

Each power supply side power supply terminal 133 is a terminal that can be used as the power supply side signal terminal 134, each power supply side signal terminal 134 is a terminal that can be used as the power supply side power supply terminal 133, and each device side power supply terminal 163 is a device side signal. Each device-side signal terminal 164 is a terminal that can be used as the device-side power supply terminal 163.
Thereby, in each terminal group of the power supply side terminal group 130 and the device side terminal group 160, the power supply terminals 133 and 163 and the signal terminals 134 and 164 are compatible for power supply and signal transmission. The degree of freedom in selecting the power supply terminals 133 and 163 and the signal terminals 134 and 164 in the connectors 101 and 102 is increased, and the convenience of the connector device 100 can be improved.
In addition, each power supply side power supply terminal 133 and each power supply side signal terminal 134 are configured by power supply side terminals 136 having the same structure, and each device side power supply terminal 163 and each device side signal terminal 164 are configured by a device side terminal 166 having the same structure. Thus, the cost of the connector device 100 can be reduced.

  All the electric devices 70 are fed in parallel through two power feeding side power supply terminal groups 131 and two device side power feeding terminal groups 161 arranged in parallel, so that the power feeding side power feeding terminal group 131 and the device side power feeding terminals are provided. When a failure such as an energization failure occurs in one pair with the group 161 and power supply to the electric device 70 through the one pair becomes impossible, the power supply side power supply terminal group 131 and the device side Since the power supply to the electric device 70 is ensured by the other pair with the power supply terminal group 161, the stability of the power supply to the electric device 70 can be improved.

  The power supply side connector 101 has a pair of inclined guide portions 115 and a pair of concave guide portions 117, and the device side connector 102 has a pair when the terminal groups 130 and 160 occupy the alignment position in the lateral direction. Each of the inclined guide portions 115 is connected in the direction of connection with the convex guide portion 157 when the floor head 20 is moved in the connection direction. , The floor head base 20 is moved in the lateral direction to have the inclined surface 115a for guiding the pair of convex guide portions 157 to the pair of concave guide portions 117. When the power supply side terminal group 130 and the device side terminal group 160 are separated from each other in the connection direction, the shape guide portion 157 is fitted while being engaged in the horizontal direction, thereby moving the floor head base 20 in the connection direction. invite.

Thus, when the floor head 20 is moved and the connectors 101 and 102 are connected, the power supply side terminal group 130 and the device side terminal group 160 are placed at the position of the device side connector 102 with respect to the power supply side connector 101. If there is a lateral misalignment that makes the connection impossible, any of the pair of convex guides 157 in the process in which the floor head 20 is brought closer to the wall 10 in the connection direction, A pair of convex guide portions 157 and a pair of concave guide portions 117 are fitted together by being guided by the inclined surface 115a of the inclined guide portion 115 facing in the connecting direction among the pair of inclined guide portions 115. Then, the floor head base 20 is positioned in the lateral direction with respect to the wall 10 so that the power supply side terminal group 130 and the device side terminal group 160 can contact and separate, and then a pair of convex guide portions 157 and the fitting shape of the pair of concave guide portions 117 In both connectors 101, 102 are connected. Thus, the pair of inclined guide portions 115 eliminates the positional displacement of the floor head base 20 with respect to the wall 10 in the lateral direction, so that both the connectors 101 and 102 can be easily connected.
In addition, since the power supply side terminal group 130 and the device side terminal group 160 do not contact each other until the positional deviation of the floor mount 20 in the lateral direction is eliminated, the device side terminal group 160 protrudes from the facing surface 153 in the connection direction. Even when the power supply terminal 163 or the signal terminal 164 is damaged, it is possible to prevent the power supply terminal 163 or the signal terminal 164 from being damaged due to the lateral movement of the floor base 20.

The concave guide portion 117 and the convex guide portion 157 extend in parallel in the vertical direction, and the vertical width W12 of the concave guide portion 117 is larger than the vertical width W22 of the convex guide portion 157.
Accordingly, a structure for enabling the connection state of both the connectors 101 and 102 while allowing the positional deviation in the vertical direction with respect to the wall 10, that is, the concave guide portions 117 and the convex shapes that are the vertical positional deviation allowable structure. Since the vertical width W22 of each convex guide portion 157 is smaller than the vertical width W12 of each concave guide portion 117, the guide portion 157 has a small device-side connector 102 attached to the movable floor head base 20. The weight can be reduced. For this reason, the weight increase of the floor head base 20 to which the apparatus side connector 102 is attached can be suppressed, and the ease of movement of the floor head base 20 can be improved.
Furthermore, since the vertical position shift allowance structure is each concave guide portion 117 and each convex guide portion 157, a mechanism that allows the device-side connector to move the device-side connector in the vertical direction with respect to the floor head 20 is provided. Compared with the case where it is provided, since the structure for allowing the positional deviation in the vertical direction is simplified, the device-side connector 102 can be reduced in size and weight, and the cost of the connector device 100 can be reduced. be able to.
