Here, FIGS. 3, 5, and 6 are cross-sectional views taken along the connection directions (D1-D2 directions) of the relay connector 10, the transmitter 50, and the probe 60.
In the following description, the inside or outside in the direction orthogonal to the connection direction (D1-D2 direction) may be referred to as inside or outside, respectively.

The relay connector 10 according to the present embodiment is first connected to the connection 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, the main body of the 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 connection portion 51 on the back side (relay connector 10 side), and the connection portion 51 is provided with a connection 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 portions constituting the recess 53, respectively. (FIG. 4, FIG. 5, FIG. 6). The locking portion of the upper wall portion is a recess recessed to the upper side (upper side in each figure), and the locking portion of the bottom wall portion is a wall portion recessed to the lower side (lower side in each figure). Here, if the wall portion constituting the recess 53 is formed of, for example, silicone rubber or synthetic rubber as a material having elasticity and liquidtightness, adhesion and liquidtightness are ensured when connected to the relay connector 10. It is preferable because it can be done.

The probe 60 as an electrical component is connected to an electrocardiograph or palmoximeter connected to the patient's body to obtain vital data such as the patient's ECG (electrocardiogram) and SPO ₂ (percutaneous arterial oxygen saturation). Output to the transmitter 50 side. Here, the electric component gives data and signals according to the type, specifications, and the like to 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 (relay connector 10 side) along the connection direction (D1-D2 direction). The contact 61 is surrounded by a non-conductive cover portion 62 provided on the outside in the plane direction orthogonal to the connection direction. Here, if the cover portion 62 is made of, for example, silicone rubber or synthetic rubber as a material having elasticity and liquidtightness, it is preferable because adhesion and liquidtightness can be ensured 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 bar 20 is made of a hard material having durability and wear resistance, and is provided in a pair at the corresponding upper and lower positions, and the moving path 16 provided inside the relay connector 10 (FIGS. 5 and 6). Each is inserted inside. 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). By inserting the push bar 20 into the movement path 16, the push bar 20 can move along the connection direction (D1-D2 direction).

The relay connector 10 is provided with a restricted space 17 (FIG. 6) at an intermediate position in the connection direction (D1-D2 direction) so as to form a space connected to each movement path 16. The restricted space 17 is formed toward the inside of the relay connector 10 in a 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 so as to project inward of 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 (tip side in the D1 direction, transmitter 50 side) of the protrusion 21. The coil spring 30 is expandable and contractible along the connection direction in the restricted space 17. In the restricted space 17, the protrusion 21 is urged 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 no external force in the connection direction is applied to the protrusion 21, the protrusion 21 is the most in the restricted space 17. It is located on the back side (tip side in the D2 direction, probe 60 side).

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

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

When the first cover portion 12, the second cover portion 13, and the third cover portion 18 are formed of, for example, silicone rubber or synthetic rubber as a material having elasticity and liquidtightness, 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 liquidtightness can be ensured, which is preferable.

Hooks 40 are arranged on the tip side (tip side in the D1 direction) of the relay connector 10 and on the outside of the pair of moving paths 16 (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 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 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 (outside in the plane orthogonal to the D1-D2 direction) on the tip side of the bent portion 42, and the tip portion 43 (locking end) facing the outside of the relay connector 10. Department). Due to its elasticity, the hook 40 can be deformed to the inside or the outside of the relay connector 10 in a state where the rear end portion 41 is supported.

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

The shapes of the inner side surface 12a of the first cover portion 12 and the outer surface of the connecting portion 51 correspond to each other, and further, 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 state where liquid does not pass through. Therefore, it is possible to prevent liquids and foreign substances from entering the transmitter 50 and the relay connector 10 from the connection portion 51.

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 the rearmost side (the side farthest from the transmitter 50) in the restricted space 17 due to 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 urging force on the hook 40.

Subsequently, the probe 60 is connected to the relay connector 10 connected to the transmitter 50. This connection is made 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 the connection hole 15 pass through the electrically conductive film. Conducting 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 shapes of the inner side surface 13a of the second cover portion 13 and the outer surface of the cover portion 62 correspond to each other, when the contact 61 is inserted into the connection hole 15, the second cover portion 13 and the cover portion are formed. 62 are connected to each other in a liquidtight state. Therefore, it is possible to prevent liquids and foreign substances 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 a direction orthogonal to the connection direction (D1-D2 direction). Therefore, when the probe 60 is inserted toward the transmitter 50, the tip of the cover portion 62 comes into contact with 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 a state where the connection between the relay connector 10 and the probe 60 is completed, as shown in FIG. 6, the push bar 20 resists the elastic force of the coil spring 30 and is on the tip side (transmitter) in the regulated space 17. Located on the 50 side). At this time, the position of the probe 60 in the connecting direction is maintained by the frictional force between the outer surface thereof 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 on the bent portion 42 of the hook 40 from the inside and urges the hook 40 to the outside. .. Due to this urging, the tip portion 43 of the hook 40 is displaced so as to protrude outward from the state shown in FIG. 5, and protrudes outward from the third cover portion 18 of the relay connector 10 to lock the transmitter 50. Go inside 54. Therefore, the hook 40 is locked to the locking portion 54, the movement of the relay connector 10 to the rear 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 removed 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 urging force on the hook 40 by the push bar 20 is lost, so that the tip portion 43 is disengaged 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 simply by 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 by the deformation of the hook 40 due to the displacement of the push bar 20. Further, since each connection point is configured to be liquid-tight, it is possible to reliably prevent the ingress of dust, foreign matter, moisture and the like.

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

A modification of the above 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 modified example are connected to each other and the probe 60 is not connected to each other. 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. In FIGS. 7 and 8, the same configurations 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 bar 120 is made of a hard material having durability and wear resistance, and is provided in a pair at corresponding upper and lower positions and is provided inside the relay connector 110, similarly to the push bar 20 of the above embodiment. It is inserted into each of the moving paths 116. The movement path 116 is a space provided so as to penetrate the inside of the relay connector 110 along the connection direction (D1-D2 direction). By inserting the push bar 120 into the movement path 116, the push bar 120 can move along the connection direction (D1-D2 direction).

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

The push bar 120 is provided with a protrusion 121 at an intermediate position in the connection direction. The protrusion 121 is formed so as to project inward of 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, a first coil spring 130 (elastic member), which is a compression spring, is arranged on the front side (tip side in the D1 direction, transmitter 50 side) of the protrusion 121. The first coil spring 130 is expandable and contractible along the connection direction in the restricted space 117. In the restricted space 117, the protrusion 121 is urged 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 no external force in the connection direction is applied to the protrusion 121, the protrusion 121 is the rearmost side (tip in the D2 direction) in the restricted space 117. Side, 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 with respect to the protrusion 121 along the D1 direction. When an external force is applied, the protrusion 121 (push bar 120) resists the elastic force of the first coil spring 130 and the front side (tip side in the D1 direction, transmitter) in the regulated space 117. Move to the 50 side).

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

Similar to the contact 11, the connection portion 14, and the connection hole 15 of the above embodiment, the relay connector 110 has a plurality of contacts extending from the front side (tip side in the D1 direction, transmitter 50 side) along the connection direction. The 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 provided on the outside in the plane direction orthogonal to the connection direction. The connecting portion 114 is surrounded by a non-conductive second cover portion 113 provided on the outside in the plane direction orthogonal to the connecting direction. The first cover portion 112 is surrounded by a non-conductive third cover portion 118 provided on the outside in the plane 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, for example, silicone rubber or synthetic rubber as a material having elasticity and liquidtightness, 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 liquidtightness can be ensured, which is preferable.

Hooks 140 are arranged on the tip side (tip side in the D1 direction) of the relay connector 110 and on the outside of the pair of moving paths 116 (outside in the plane orthogonal to the D1-D2 direction).

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

On the transmitter 50 side of the hook 140, the inclined surface 142 extends from the innermost bottom surface 143 in the direction orthogonal to the connection direction toward the probe 60 side. The bottom surface 143 is a plane extending along the connection direction, and the inclined surface 142 is a plane having an inclination toward the outside toward the probe 60 side. The inclination angle and the planar shape of the inclined surface 142 correspond to the inclined angle and the planar shape of the first side surface 122a of the end portion 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 outward in a 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 the rearmost side (the side far 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, the push bar 120 has only the first side surface 122a of the end portion 122 in contact with the inclined surface 142 of the hook 140.

Subsequently, similarly to the above embodiment, the probe 60 is connected to the relay connector 110 connected to the transmitter 50. The cover portion 62 inserted into the second cover portion 113 is arranged at a position corresponding to the push bar 120 in a direction orthogonal to the connection direction (D1-D2 direction). Therefore, when the probe 60 is inserted toward the transmitter 50, the tip of the cover portion 62 comes into contact with the rear end of the push bar 120, and as the probe 60 moves, the elastic force of the first coil spring 130 is applied. The push bar 120 moves to the transmitter 50 side against it. Then, in a state where the connection between the relay connector 110 and the probe 60 is completed, as shown in FIG. 8, the push bar 120 resists the elastic force of the first coil spring 130 and is on the tip side (in the restricted space 117). It is located on the transmitter 50 side). At this time, the position of the probe 60 in the connecting direction is maintained by the frictional force between the outer surface thereof and the inner surface of the second cover portion 113.

In the process of inserting the probe 60 to the innermost part of the second cover portion 113, the first side surface 122a of the end portion 122 abuts on the inclined surface 142 of the hook 140 as the push bar 120 moves toward the transmitter 50 side. 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 where the second side surface 122b abuts on the bottom surface 143 (FIG. 8). 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 connection 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 displacement of the outside of the hook 140, the locking end portion 144 is displaced so as to protrude outward from the state shown in FIG. 7, and protrudes outward from the third cover portion 118 of the relay connector 110 to the transmitter. It enters the locking portion 54 of the 50. Therefore, the hook 140 is locked to the locking portion 54, the movement of the relay connector 110 to the rear 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 removed from the relay connector 110, the external force on the push bar 120 disappears, so that the push bar 120 is in the initial position according to the elastic force of the first coil spring 130 (FIG. 5). Restore to position). As a result, the urging force on the hook 140 by the push bar 120 is lost, so that the locking end portion 144 is disengaged 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. ..
