FIG. 5 is a cross-sectional view showing a state in which the relay connector 10 and the transmitter 50 are connected to each other and the probe 60 is not connected. FIG. 6 is a cross-sectional view showing a state in which the relay connector 10, the transmitter 50, and the probe 60 are connected to each other. Here, FIG. 3, FIG. 5, and FIG. 6 are cross-sectional views taken along the connection direction (D1-D2 direction) of the relay connector 10, the transmitter 50, and the probe 60.
In the following description, the inside or outside of the direction orthogonal to the connection direction (D1-D2 direction) may be referred to as the inside or outside, respectively.

  The relay connector 10 according to the present embodiment is first connected to the connecting portion 51 of the transmitter 50 as the target device (FIG. 5). Next, by connecting the probe 60 as an electric component to the relay connector 10 connected to the transmitter 50, the transmitter 50 and the probe 60 are electrically connected to each other via the relay connector 10. (Fig. 6).

  The transmitter 50 as the target device is, for example, a main body of a telemetry transmitter, but the target device is not limited to this. As shown in FIGS. 1 and 4, the transmitter 50 is provided with a connecting portion 51 on the back side (relay connector 10 side), and the connecting portion 51 is provided with a connecting hole 52. The connecting portion 51 is provided in the non-conductive recess 53, and two locking portions 54 are provided at corresponding positions of the upper and lower wall portions of the wall portion forming the recess 53. (FIG. 4, FIG. 5, FIG. 6). The locking portion of the upper wall portion is a recessed portion that is recessed upward (upper side of each drawing), and the locking portion of the bottom wall portion is a wall portion that is recessed downward (lower side of each drawing). Here, when the wall portion forming the concave portion 53 is formed of a material having elasticity and liquid tightness, for example, silicone rubber or synthetic rubber, when the relay connector 10 is connected, adhesion and liquid tightness are secured. It is preferable because it is possible.

The probe 60 as an electric component is connected to an electrocardiograph or a paroximeter connected to the body of the patient, and outputs vital data such as the patient's ECG (electrocardiogram) and SPO ₂ (percutaneous arterial blood oxygen saturation). Output to the transmitter 50 side. Here, the electric component gives data and a signal according to the type and specifications of the target device, and is not limited to the probe.

  As shown in FIGS. 5 and 6, the probe 60 includes a plurality of contacts 61 extending from the front side (the relay connector 10 side) in the connection direction (D1-D2 direction). The contact 61 is surrounded by a non-conductive cover portion 62 provided on the outer side in the surface direction orthogonal to the connection direction. Here, it is preferable that the cover portion 62 is formed of a material having elasticity and liquid tightness, for example, silicone rubber or synthetic rubber, since the adhesiveness and liquid tightness can be secured when the cover portion 62 is connected to the relay connector 10.

As shown in FIG. 3, the relay connector 10 includes a push bar 20, a coil spring 30 as an elastic member, and a hook 40.
The push bars 20 are made of a hard material having durability and wear resistance, and a pair of push bars 20 are provided at corresponding upper and lower positions, and a moving path 16 provided inside the relay connector 10 (FIGS. 5 and 6). It is inserted in each. The movement path 16 is a space provided so as to penetrate the inside of the relay connector 10 along the connection direction (D1-D2 direction). The push bar 20 can be moved along the connecting direction (D1-D2 direction) by being inserted into the moving path 16.

  The relay connector 10 is provided with a regulation space 17 (FIG. 6) at an intermediate position in the connection direction (D1-D2 direction) so as to form a space continuous with each moving path 16. The regulation space 17 is formed toward the inside of the relay connector 10 in the direction orthogonal to the connection direction.

  The push bar 20 is provided with a protrusion 21 at an intermediate position in the connection direction. The protrusion 21 is formed to protrude inside the relay connector 10 in a direction orthogonal to the connection direction (D1-D2 direction).

  As shown in FIGS. 3, 5 and 6, the protrusion 21 of the push bar 20 is arranged in the restricted space 17. In the restricted space 17, a coil spring 30 (elastic member), which is a compression spring, is arranged on the front side (the tip side in the D1 direction, the transmitter 50 side) of the protrusion 21. The coil spring 30 is capable of expanding and contracting in the restricted space 17 along the connecting direction. In the regulation space 17, the protrusion 21 is biased in the D2 direction by the elastic force of the coil spring 30. Therefore, as shown in FIG. 5, when the probe 60 is not inserted into the relay connector 10 and the external force in the connecting direction is not applied to the protruding portion 21, the protruding portion 21 is the most inside the restricted space 17. It is located on the back side (the tip side in the D2 direction, the probe 60 side).

  On the other hand, as shown in FIG. 6, the probe 60 is inserted into the relay connector 10 to connect the relay connector 10 and the probe 60, and the probe 60 is moved in the D1 direction along the D1 direction with respect to the protrusion 21. When an external force for advancing is applied, the protrusion 21 (push bar 20) resists the elastic force of the coil spring 30, and the front side (the tip side in the D1 direction, the transmitter 50 side) in the restricted space 17 is pushed. ) To.

  As shown in FIG. 2A or FIG. 2B, the relay connector 10 includes a plurality of contacts 11 extending from the front side (the tip side in the D1 direction, the transmitter 50 side) along the connection direction. On the back side, a connecting portion 14 having a plurality of connecting holes 15 is provided. The plurality of contacts 11 and the plurality of connection holes 15 are provided at the corresponding positions, and are electrically connected to each other. Further, an electrically conductive film is formed on the inner surface of the connection hole 15. The contact 11 is surrounded by a non-conductive first cover portion 12 provided on the outer side in the surface direction orthogonal to the connection direction. The connection portion 14 is surrounded by the non-conductive second cover portion 13 provided on the outer side in the plane direction orthogonal to the connection direction. The first cover portion 12 is surrounded by a non-conductive third cover portion 18, which is provided on the outer side in the plane direction orthogonal to the connection direction.

  When the first cover part 12, the second cover part 13, and the third cover part 18 are formed of a material having elasticity and liquid tightness, for example, silicone rubber or synthetic rubber, the relay connector 10 and the transmitter 50 are formed. When the (target device) and the probe 60 (electrical component) are connected to each other, adhesion and liquid tightness can be secured, which is preferable.

  Hooks 40 are arranged on the tip side of the relay connector 10 (the tip side in the D1 direction) and on the outside of the pair of movement paths 16 (the outside in the plane orthogonal to the D1-D2 direction). The hook 40 is made of a material that is elastically deformable and has wear resistance. As shown in FIGS. 5 and 6, the hook 40 has a rear end portion 41 fixed to the relay connector 10 and extends toward the transmitter 50. In the middle of the hook 40 extending from the rear end portion 41, a bent portion 42 that is bent toward the inside of the relay connector 10 (inside in the plane orthogonal to the D1-D2 direction) is provided. The hook 40 is bent to the outside of the relay connector 10 (to the outside in the plane orthogonal to the D1-D2 direction) on the tip side of the bent portion 42, and is directed to the outside of the relay connector 10 (the locking end 43). Department). The elasticity of the hook 40 allows the hook 40 to be deformed inside or outside the relay connector 10 with the rear end portion 41 being supported.

Next, the connection between the relay connector 10, the transmitter 50, and the probe 60 will be described.
The relay connector 10 is first connected to the transmitter 50. This connection is performed by inserting the contacts 11 of the relay connector 10 into the connection holes 52 of the connection portion 51 of the transmitter 50 (FIG. 5). As a result, the contact 11 is electrically connected to a conductive member (not shown) in the transmitter 50.

  The inner surface 12a of the first cover portion 12 and the outer surface of the connecting portion 51 correspond to each other in shape, and the outer surface of the third cover portion 18 and the inner surface of the recess 53 correspond to each other in shape. When the contact 11 is inserted into the connecting portion 51, the connecting portion 51 and the first cover portion 12 are connected to each other in a liquid-tight state, that is, in a liquid-impermeable state. Therefore, it is possible to prevent liquid or foreign matter from entering the transmitter 50 from the connecting portion 51 and into the relay connector 10.

  In the state where the relay connector 10 and the transmitter 50 are connected in this way, as shown in FIG. 5, the push bar 20 is moved to the rearmost side (the side farthest from the transmitter 50) in the restricted space 17 by the elastic force of the coil spring 30. ) Is located. At this time, the push bar 20 is only in contact with the hook 40 and does not exert an outward biasing force on the hook 40.

  Subsequently, the probe 60 is connected to the relay connector 10 connected to the transmitter 50. This connection is performed by inserting the plurality of contacts 61 of the probe 60 into the plurality of connection holes 15 provided in the connection portion 14 of the relay connector 10, respectively. Since an electrically conductive film is formed on the inner surface of the connection hole 15, the contact 61 inserted into the connection hole 15 and the contact 11 corresponding to this connection hole 15 are formed through this electrically conductive film. Conduct with each other. As a result, the transmitter 50 and the probe 60 are electrically connected via the relay connector 10 (FIG. 6).

  Here, since the inner side surface 13a of the second cover portion 13 and the outer side surface of the cover portion 62 correspond to each other in shape, when the contact 61 is inserted into the connection hole 15, the second cover portion 13 and the cover portion 62 are inserted. 62 are connected to each other in a liquid-tight state. Therefore, it is possible to prevent liquid or foreign matter from entering the relay connector 10 and the probe 60.

  The cover portion 62 inserted into the second cover portion 13 is arranged at a position corresponding to the push bar 20 in the direction orthogonal to the connecting direction (D1-D2 direction). For this reason, when the probe 60 is inserted into the transmitter 50 side, the tip of the cover portion 62 abuts on the rear end of the push bar 20, and as the probe 60 moves, it opposes the elastic force of the coil spring 30. The push bar 20 moves to the transmitter 50 side. Then, in the state in which the connection between the relay connector 10 and the probe 60 is completed, the push bar 20 resists the elastic force of the coil spring 30 in the restricted space 17 as shown in FIG. 50 side). At this time, the position of the probe 60 in the connection direction is maintained by the frictional force between the outer surface of the probe 60 and the inner surface of the second cover portion 13.

  When the probe 60 is inserted all the way into the second cover portion 13, the tip portion 22 of the push bar 20 abuts the bent portion 42 of the hook 40 from the inside and biases the hook 40 to the outside. . Due to this biasing, the tip end portion 43 of the hook 40 is displaced so as to project outward from the state shown in FIG. 5, and projects outward from the third cover portion 18 of the relay connector 10 to lock the transmitter 50. Step into 54. Therefore, the hook 40 is locked by the locking portion 54, the rearward movement of the relay connector 10 is restricted, and the relay connector 10 is prevented from coming off from the transmitter 50.

  On the other hand, when the probe 60 is moved to the rear side and detached from the relay connector 10, the external force on the push bar 20 disappears, so that the push bar 20 is in the initial position (position in FIG. 5) according to the elastic force of the coil spring 30. Recover to. As a result, the pushing force of the push bar 20 on the hook 40 disappears, and the tip end 43 disengages from the locking portion 54 of the transmitter 50, and the locking of the transmitter 50 and the relay connector 10 by the hook 40 is released.

  As described above, the relay connector 10 can electrically connect the transmitter 50 and the probe 60 by simply performing the simple operation of inserting the probe 60 in the state of being connected to the transmitter 50. In addition, the hook 40 can be reliably prevented from coming off due to the deformation of the hook 40 caused by the displacement of the push bar 20. Furthermore, since each connecting portion is configured to be liquid-tight, it is possible to reliably prevent infiltration of dust, foreign matter, water, and the like.

  Here, in the regulation space 17, the protrusion 21, and the coil spring 30, as described above, the push bar 20 is biased to the back side by the elastic force of the coil spring 30, and the probe 60 is moved to the relay connector 10. If the push bar 20 can be moved to the front side by connecting, the configuration and arrangement other than the above may be adopted. Further, as the elastic member that biases the push bar 20, an elastic member other than the coil spring 30 may be used.

  A modified example of the above-described embodiment will be described with reference to FIGS. 7 and 8. FIG. 7 is a partially enlarged view of a cross-sectional view showing a state in which the relay connector 110 and the transmitter 50 according to the modification are connected to each other and the probe 60 is not connected. FIG. 8 is a partially enlarged view of a cross-sectional view showing a state in which the relay connector 110, the transmitter 50, and the probe 60 according to the modified example are connected to each other. 7 and 8, the same components as those in the above embodiment are designated by the same reference numerals, and detailed description thereof will be omitted.

  The relay connector 110 includes a push bar 120, a first coil spring 130 as an elastic member, a second coil spring 131 as a second elastic member, and a hook 140.

  The push bars 120 are made of a hard material having durability and abrasion resistance, and like the push bar 20 of the above-described embodiment, a pair of push bars are provided at corresponding upper and lower positions and are provided inside the relay connector 110. Are inserted into the respective moving paths 116. The moving path 116 is a space provided so as to penetrate the inside of the relay connector 110 along the connection direction (D1-D2 direction). The push bar 120 can be moved along the connecting direction (D1-D2 direction) by inserting the push bar 120 in the moving path 116.

  The relay connector 110 is provided with a regulation space 117 (FIG. 8) at an intermediate position in the connection direction (D1-D2 direction) so as to form a space continuous with each moving path 116. The regulation space 117 is formed toward the inside of the relay connector 110 in the direction orthogonal to the connection direction.

  The push bar 120 is provided with a protrusion 121 at an intermediate position in the connecting direction. The protrusion 121 is formed so as to protrude inside the relay connector 110 in a direction orthogonal to the connection direction (D1-D2 direction).

  The protrusion 121 of the push bar 120 is arranged in the restricted space 117. In the restricted space 117, the first coil spring 130 (elastic member), which is a compression spring, is arranged on the front side (the tip side in the D1 direction, the transmitter 50 side) of the protrusion 121. The first coil spring 130 is capable of expanding and contracting in the restricted space 117 along the connecting direction. In the restricted space 117, the protrusion 121 is biased in the D2 direction by the elastic force of the first coil spring 130. Therefore, when the probe 60 is not inserted into the relay connector 110 and the external force in the connecting direction is not applied to the protrusion 121, the protrusion 121 is located on the rearmost side (the tip in the D2 direction) in the regulation space 117. Side, the probe 60 side).

  On the other hand, as shown in FIG. 8, the probe 60 is inserted into the relay connector 110 to connect the relay connector 110 and the probe 60, and the probe 60 is moved in the D1 direction along the D1 direction with respect to the protrusion 121. When an external force for advancing is applied, the protrusion 121 (push bar 120) resists the elastic force of the first coil spring 130 and the front side (the tip side in the D1 direction, the transmitter in the restricted space 117). 50 side).

  In the push bar 120, the end portion 122 of the transmitter 50 on the connecting portion 51 side has two continuous side surfaces, that is, a first side surface 122a and a second side surface 122b. The first side surface 122a is the side surface closest to the connecting portion 51 side, and is a flat surface inclined toward the inside in the direction orthogonal to the connecting direction as it goes toward the connecting portion 51 side, that is, the tip. The second side surface 122b is continuous with the first side surface 122a on the probe 60 side and forms a flat surface extending along the connection direction.

  Similar to the contact 11, the connection portion 14, and the connection hole 15 of the above-described embodiment, the relay connector 110 includes a plurality of contacts extending from the front side (the tip side in the D1 direction, the transmitter 50 side) along the connection direction. 111 is provided, and a connection portion 114 having a plurality of connection holes 115 is provided on the back side. The contact 111 is surrounded by a non-conductive first cover portion 112 that is provided on the outer side in the surface direction orthogonal to the connection direction. The connection portion 114 is surrounded by a non-conductive second cover portion 113 that is provided outside in the surface direction orthogonal to the connection direction. The first cover portion 112 is surrounded by a non-conductive third cover portion 118 that is provided outside in the surface direction orthogonal to the connection direction.

  When the first cover portion 112, the second cover portion 113, and the third cover portion 118 are formed of a material having elasticity and liquid tightness, for example, silicone rubber or synthetic rubber, the relay connector 110 and the transmitter 50 are formed. When the (target device) and the probe 60 (electrical component) are connected to each other, adhesion and liquid tightness can be secured, which is preferable.

  Hooks 140 are arranged on the distal end side of the relay connector 110 (the distal end side in the D1 direction) and on the outer side of the pair of movement paths 116 (the outer side in the plane orthogonal to the D1-D2 direction).

  The hook 140 is made of a hard material having durability and wear resistance, and includes a recess 141 on the probe 60 side in which one end of the second coil spring 131 is accommodated. The other end of the second coil spring 131 serving as the second elastic member is fixed to the inner surface of the second cover 113. As a result, the second coil spring 131 is arranged to be expandable / contractible along the direction orthogonal to the connection direction, and the elastic force thereof urges the hook 140 inward in the direction orthogonal to the connection direction. By providing the second coil spring 131 in this way, movement of the hook 140 toward the transmitter 50 side or the probe 60 side is restricted.

  On the transmitter 50 side of the hook 140, an inclined surface 142 extends toward the probe 60 from a bottom surface 143 located on the innermost side in the direction orthogonal to the connection direction. The bottom surface 143 is a flat surface that extends along the connection direction, and the inclined surface 142 is a flat surface that is inclined outward toward the probe 60 side. The inclination angle and the planar shape of the inclined surface 142 correspond to the inclination angle and the planar shape of the first side surface 122a of the end 122 of the push bar 120, respectively.

  Further, on the transmitter 50 side of the hook 140, a locking end portion 144 is provided so as to extend to the outside in the direction orthogonal to the connection direction.

Next, the connection between the relay connector 110 and the transmitter 50 and the probe 60 will be described.
The relay connector 110 is first connected to the transmitter 50 as in the above embodiment. In the state where the relay connector 110 and the transmitter 50 are connected, as shown in FIG. 7, the push bar 120 is located at the rearmost side (the side farther from the transmitter 50) in the restricted space 117 due to the elastic force of the first coil spring 130. Is located in. At this time, in the push bar 120, the first side surface 122 a of the end portion 122 is only in contact with the inclined surface 142 of the hook 140.

  Subsequently, the probe 60 is connected to the relay connector 110 connected to the transmitter 50, as in the above embodiment. The cover part 62 inserted into the second cover part 113 is arranged at a position corresponding to the push bar 120 in the direction orthogonal to the connection direction (D1-D2 direction). Therefore, when the probe 60 is inserted into the transmitter 50 side, the tip of the cover portion 62 comes into contact with the rear end of the push bar 120, and the elastic force of the first coil spring 130 is applied to the movement of the probe 60. Reversely, the push bar 120 moves to the transmitter 50 side. Then, in the state where the connection between the relay connector 110 and the probe 60 is completed, the push bar 120 resists the elastic force of the first coil spring 130 and the distal end side (in the regulation space 117 as shown in FIG. Located on the transmitter 50 side). At this time, the position of the probe 60 in the connection direction is maintained by the frictional force between the outer surface of the probe 60 and the inner surface of the second cover 113.

  As the push bar 120 moves toward the transmitter 50, the first side surface 122a of the end 122 abuts the inclined surface 142 of the hook 140 in the process of inserting the probe 60 into the deepest part of the second cover 113. From the position (FIG. 7), the push bar 120 moves to the inside of the bottom surface 143, and further, the push bar 120 moves to the position (FIG. 8) where the second side surface 122b contacts the bottom surface 143. With such movement of the push bar 120, the hook 140 is pushed outward by the push bar 120 against the elastic force of the second coil spring 131, and is displaced outward in the direction orthogonal to the connecting direction. That is, the hook 140 is displaced outward according to the shape of the side surface (first side surface 122a, second side surface 122b) of the end portion 122 of the push bar 120.

  Due to such an outer displacement of the hook 140, the locking end 144 is displaced so as to project further outward than the state shown in FIG. 7, and projects outward from the third cover part 118 of the relay connector 110 to transmit the transmitter. It enters into the locking portion 54 of 50. Therefore, the hook 140 is locked by the locking portion 54, the rearward movement of the relay connector 110 is restricted, and the relay connector 110 is prevented from coming off from the transmitter 50.

On the other hand, when the probe 60 is moved to the rear side and detached from the relay connector 110, the external force on the push bar 120 disappears, so the push bar 120 is moved to the initial position (see FIG. 5) according to the elastic force of the first coil spring 130. Position). As a result, the biasing force of the push bar 120 with respect to the hook 140 disappears, so that the locking end portion 144 disengages from the locking portion 54 of the transmitter 50, and the locking of the transmitter 50 and the relay connector 110 by the hook 140 is released. .
