Description

  The present invention relates to an electrical connector unit connectable to a sheet-like connected member.

  2. Description of the Related Art An electrical connector connected to a connected substrate such as a flexible printed circuit board is known (for example, see Patent Documents 1 and 2). The relay connector as an electrical connector described in Patent Document 1 includes a first clip member, a second clip member, and a probe. The first clip member is connected to the second clip member via a swing support shaft.

  When the worker connects the board to be connected to the relay connector, the worker grasps the first clip member and the second clip member to relatively displace the first clip member and the second clip member around the swing support shaft. Let Thereafter, the worker releases the above-described picking operation in a state where the connected substrate is disposed between the first clip member and the second clip member. As a result, the first clip member and the second clip member are relatively displaced around the swing support shaft by the force of the spring disposed between the first clip member and the second clip member. Accordingly, the first clip member and the second clip member are displaced so as to sandwich the connected substrate. Thereby, the probe fixed to the 2nd clip member contacts a to-be-connected board. The contacted substrate and the relay connector are electrically connected by contact between the probe and the connected substrate.

  By the way, the electrical connector may be used in the medical field or the like. For example, an electrical connector may be used as part of a device for detecting the presence or absence of treatment abnormalities on a patient. As a more specific example, the electrical connector may be used as part of a monitoring device that monitors anomalies that occur during a dialysis procedure on an artificial dialysis patient.

  The monitoring device has, for example, a sheet-like liquid detection sensor, an electrical connector unit, and a control device. The liquid detection sensor has, for example, a configuration in which a conductor is formed on a nonwoven fabric as disclosed in Patent Document 3. The liquid detection sensor is installed near the tip of a dialysis needle. The needle is pierced by the patient during the patient's dialysis. The liquid detection sensor is attached to the electrical connector unit.

  The electrical connector unit includes an electrical connector attached to the liquid detection sensor and an electric wire connected to the control device. Here, it is conceivable to use the relay connector described in Patent Documents 1 and 2 as the electrical connector. In this case, the relay connector sandwiches the liquid detection sensor, and the probe contacts the conductor of the liquid detection sensor.

  Then, when bleeding occurs from around the needle stabbed by the patient, the liquid detection sensor absorbs the patient's blood. As a result, the electrical resistance value of a part of the liquid detection sensor decreases, and this change is detected by the control device. As a result, the control device performs processing such as sounding an alarm, and notifies the doctor or the like of the abnormality. Further, for example, when the needle is removed from the patient due to carelessness of the patient, the liquid detection sensor is removed from the electrical connector by being displaced together with the needle. As a result, the electrical resistance at the probe of the electrical connector increases and this change is detected by the control device. Along with this, the control device performs processing such as sounding an alarm and notifies the surroundings of the abnormality.

  As described above, when the liquid detection sensor is sandwiched between the electrical connectors, the liquid detection sensor needs to ensure that the electrical connection with the electrical connector is ensured in order to notify the control device that the patient has bleeded. There is. On the other hand, in order to detect the removal of the needle, the liquid detection sensor needs to smoothly come out of the electrical connector with the displacement of the needle when receiving a pulling force of a predetermined value or more.

  However, in the relay connector described in Patent Documents 1 and 2, the rigid probe comes into contact with the conductor. For this reason, when the liquid detection sensor is pulled from the electrical connector, the probe may be caught by the liquid detection sensor, and the liquid detection sensor may not easily come off from the electrical connector.

  On the other hand, it is conceivable that the liquid detection sensor can be reliably removed from the electrical connector when necessary by configuring the probe so as to slightly contact the conductor. However, in this case, the contact state between the probe and the conductor becomes unstable, and it is difficult to stably maintain the electrical connection state between the probe and the conductor. Moreover, the individual difference for every relay connector will become large about the stability of the contact state of a probe and a conductor.

  In view of the above circumstances, the present invention can more reliably maintain a conductive state with a connected member in an electrical connector unit, and when the connected member needs to be removed from the electrical connector, the connected member can be smoothly connected. It is an object of the present invention to make it possible to realize a smooth pull-out operation.

  (1) In order to solve the above-described problem, an electrical connector unit according to an aspect of the present invention has a configuration in which a conductor is installed on an insulator and has a flexible sheet-like connected member; An electrical connector unit capable of being electrically connected to a predetermined electrical device, the first connector being connectable to the connected member, the second connector being connectable to the electrical device, the first connector, and the A plurality of electric wires connecting the second connector.

The plurality of electric wires include contact electric wires connected to the contacts.

  According to this configuration, the conductor of the connected member sandwiched between the housings contacts the contact portion of the contact. The contact portion is pressurized in the first direction by the contact portion spring portion. Thus, a more reliable contact (connection) between the contact portion of the contact and the conductor of the member to be connected is achieved by the spring structure using the contact portion spring portion. In addition, a relatively large force for pulling out the connected member from the housing may be applied to the connected member. In this case, since the contact portion can be displaced in the second direction away from the conductor, it can be suppressed from being caught by the connected member. Therefore, when the connected member needs to be disconnected from the first connector, a smooth disconnecting operation of the connected member can be realized. In addition, the contact portion can be displaced in the first direction and the second direction in a state in which a pressing force is applied from the contact portion spring portion. Thereby, a contact part can be displaced according to the thickness of a to-be-connected member, the dimensional tolerance of a 1st connector, etc. As a result, individual differences can be suppressed in the contact state between the contact portion and the conductor of the connected member. In this manner, the contacted member can smoothly come out of the first connector as necessary while achieving reliable contact (conduction) between the conductor of the connected member and the contact portion of the contact. The effect can be realized by the first connector.

Housed in one part.

  According to this configuration, the housing has a seesaw structure. With such a configuration, for example, the operator can easily widen the interval between the first facing portion and the second facing portion by performing an operation of gripping the first portion and the second portion. it can. Therefore, the operator can perform the operation | work which connects a to-be-connected member to a 1st connector more easily. Further, the contact and the light emitting element are collectively accommodated in the first portion of the housing. That is, the members connected to the electric wires are accommodated together in the first portion of the housing. Thereby, the structure of the 2nd part can be made simpler. As a result, the configuration of the first connector can be further simplified.

  (5) More preferably, the first connector further includes a housing spring portion for applying a force to the housing such that the first facing portion and the second facing portion approach each other.

  According to this configuration, the first facing portion and the second facing portion of the housing are pressed against each other by the housing spring portion with the connected member interposed therebetween. Then, the conductor of the connected member sandwiched between the housings comes into contact with the contact portion of the contact. The contact portion is pressurized in the first direction by the contact portion spring portion. By such a two-stage spring structure by cooperation of the housing spring portion and the contact portion spring portion, more reliable contact (connection) between the contact portion of the contact and the conductor of the connected member is achieved.

  (6) Preferably, the said light emitting element is comprised so that a different light emission aspect is realizable according to the electric power given from the said electric equipment.

  According to this configuration, the light emitting element can realize various light emitting modes. Thereby, the 1st connector can display information, such as the operation state of the equipment around the electrical connector unit, visually more clearly, for example.

  According to the present invention, in the electrical connector unit, the conductive state with the connected member can be more reliably maintained, and when the connected member needs to be disconnected from the electrical connector, a smooth disconnecting operation of the connected member can be realized. In addition, the predetermined information can be visually and clearly displayed by using the electrical connector.

The first facing portion 43 is also a portion from which the contact 33 protrudes.

  FIG. 17 is a side view of the contact 33. Referring to FIGS. 2, 4, 7, and 17, contacts 33 (33 a, 33 b) are provided to come into contact with conductor 8 (8 a, 8 b) of sheet sensor 4. In the present embodiment, a pair of contacts 33 are provided apart from each other in the width direction Y1. Each contact 33a, 33b is formed in the same shape. One contact 33a and the other contact 33b are provided to contact the corresponding first conductor 8a and second conductor 8b of the sheet sensor 4, respectively.

  The contact 33 is held by the housing 31. Most of the contacts 33 are accommodated in the accommodation chamber 51. The contact 33 is disposed in the vicinity of the front end portion of the first portion 31 a of the housing 31.

  The contact 33 is an integrally molded product formed using a conductive material. The contact 33 is made of, for example, a copper alloy as a material. The surface of the contact 33 is subjected to a plating process such as tin plating or gold plating. In this embodiment, two contacts 33a and 33b are arranged. The contact 33a is an example of the “first contact” in the present invention, and the contact 33b is an example of the “second contact” in the present invention. In the present embodiment, each contact 33 is formed in a J shape as a whole in a side view. The contact 33 is held by the first portion 31 a of the housing 31.

  The contact 33 includes a base portion 91, a pair of fixing portions 92, 92, a contact portion spring portion 93, a chevron portion 95 including the contact portion 94, and a wire coupling portion 96.

  The base portion 91 is formed in an elongated rectangular flat plate shape. The base portion 91 is disposed adjacent to the corresponding contact hole portions 45a and 45b. Fixed portions 92, 92 extend from the base portion 91.

  The fixing portions 92, 92 are portions formed in the shape of elongated pieces. The fixing portions 92 and 92 are formed by bending a part of the contact 33 with respect to the base portion 91. The fixing portions 92 and 92 are disposed at both ends of the base portion 91 in the width direction Y1. The fixing portions 92 and 92 are press-fitted and fixed in the corresponding contact fixing holes 53 and 53 of the housing 31. Thereby, the base portion 91 is connected to the housing 31 via the fixing portion 92. A curved contact portion spring portion 93 extends from the base portion 91.

  The contact portion spring portion 93 is an example of the “contact portion spring portion” in the present invention. The contact portion spring portion 93 is a plate-like portion formed in a substantially U shape in a side view and is elastically deformable. One end portion 93a of the contact portion spring portion 93 is connected to one end of the base portion 91 in the length direction X1. Accordingly, the contact portion spring portion 93 is cantilevered by the base portion 91 and the fixing portions 92 and 92. The contact portion spring portion 93 projects forward in the length direction X1. That is, the contact portion spring portion 93 swells in the pulling direction D4 opposite to the insertion direction D3 when the sheet sensor 4 is inserted between the first facing portion 43 and the second facing portion 65. . In the present embodiment, the insertion direction D3 and the drawing direction D4 are parallel to the length direction X1.

  In other words, the contact portion spring portion 93 swells toward the pulling direction D4 when the sheet sensor 4 is pulled out from between the first facing portion 43 and the second facing portion 65. The contact portion spring portion 93 is disposed in the corresponding contact hole portions 45a and 45b of the housing 31, and is disposed so as to protrude from the contact hole portion 45 toward the first facing portion 43 side. A part of the contact portion spring portion 93 on the other end portion 93b side extends in the insertion direction D3 while facing the base portion 91 in the thickness direction of the base portion 91 (first direction D1). The spring constant of the contact portion spring portion 93 is set smaller than the spring constant of the housing spring portion 34. Thereby, the spring part 93 for contact parts can be elastically deformed with high followability with respect to the displacement of the contact part 94. The contact portion spring portion 93 is configured to be elastically deformed when a load is received from the contact portion 94 of the chevron portion 95.

  The chevron portion 95 extends from the other end portion 93b of the contact portion spring portion 93 and is supported by the contact portion spring portion 93, and is formed in a substantially V shape in a side view. The base end portion 95 a of the chevron 95 extends in a curved manner from the other end portion 93 b of the contact portion spring portion 93. The apex portion of the chevron portion 95 includes a contact portion 94.

  The contact portion 94 is provided as a portion that contacts the corresponding first conductor 8a and second conductor 8b of the sheet sensor 4 in a state sandwiched between the first facing portion 43 and the second facing portion 65. The contact portion 94 is formed in a smooth curved shape, and is prevented from being caught with the sheet sensor 4. Moreover, the front-end | tip part of the chevron part 95 has faced the 2nd direction D2 side mentioned later, and it is suppressed that the sheet | seat sensor 4 and catching arise.

  The rigidity of the chevron part 95 is set higher than the rigidity of the spring part 93 for contact part. For this reason, when the contact portion 94 receives a load from the second portion 31b of the housing 31 and the conductor 8, the elastic deformation amount of the contact portion 94 (mountain portion 95) is relatively small, and mainly the contact portion spring portion. 93 is elastically deformed.

  With the above configuration, the contact portion 94 can be displaced in the first direction D1 and the second direction D2. The first direction D <b> 1 is a direction in which the contact portion 94 approaches the corresponding conductors 8 a and 8 b and is a direction orthogonal to the first facing portion 43. The second direction D2 is a direction opposite to the first direction D1, and is a direction in which the contact portion 94 moves away from the corresponding conductors 8a and 8b. In the present embodiment, the first direction D1 and the second direction D2 are orthogonal to the length direction X1 and orthogonal to the width direction Y1. In addition, when the contact portion 94 is displaced in the second direction D2 by contacting the second facing portion 65 and the corresponding conductors 8a and 8b, the contact portion spring portion 93 is elastically deformed. Thereby, the spring part 93 for contact parts gives the contact part 94 the elastic repulsion force which pressurizes the contact part 94 toward the 1st direction D1. The contact portion 94 transmits the current from the corresponding conductors 8 a and 8 b to the wire coupling portion 96 via the base portion 91.

  The wire coupling portion 96 is formed at the rear end portion of the base portion 91. The wire coupling portion 96 is electrically and mechanically connected to the corresponding wire 29 (29a, 29b) using solder or the like. The electric wires 29 a and 29 b are also connected to corresponding contacts 27 of the second connector 23.

  The electric wires 29a and 29b are examples of the “contact electric wire” in the present invention. The electric wire 29a is an example of the “first contact electric wire” in the present invention, and the electric wire 29b is an example of the “second contact electric wire” in the present invention. The electric wires 29 a and 29 b extend toward the second partition portion 42 through the side of the LED 35. The wire coupling portion 96 is adjacent to the LED 35.

  With reference to FIG. 1 and FIG. 7, LED35 is an example of the "light emitting element" of this invention. The LED 35 is provided to transmit the monitoring state of the monitoring device 1 to the periphery of the first connector 21. The LED 35 can realize different light emission modes depending on the power supplied from the main body 6. The LED 35 is fixed to the LED support portion 54 of the first portion 31a. The light emitting surface 35 a of the LED 35 faces the cover 37. Light from the LED 35 is transmitted to the outside of the first connector 21 through the cover 37. The LED 35 is connected to the corresponding electric wire 29 (29c, 29d) of the covered electric wire 22. The electric wires 29c and 29d are examples of the “light emitting element electric wire” in the present invention.

  For example, the electric wires 29c and 29d are electrically and mechanically connected to both ends of the LED 35 in the width direction Y1 using solder or the like. The electric wires 29 c and 29 d extend toward the second partition portion 42 in the accommodation chamber 51.

  With reference to FIGS. 1 and 5, the conductors 8 a and 8 b of the sheet sensor 4, the contacts 33 a and 33 b of the first connector 21, the wires 29 a and 29 b of the covered wire 22, and the second connector are configured according to the above configuration. The plurality of contacts 27 and the main body 6 form an electric circuit between the control unit 12 and the sheet sensor 4. The LED 35, the electric wires 29 c and 29 d of the covered electric wire 22, the plurality of contacts 27 of the second connector 23, and the main body 6 form an electric circuit between the control unit 12 and the LED 35.

  As described above, according to the monitoring device 1 of the present embodiment, the conductor 8 of the sheet sensor 4 sandwiched between the housings 31 contacts the contact portion 94 of the contact 33. Moreover, the contact part 94 is pressurized toward the 1st direction D1 by the spring part 93 for contact parts. Thus, the spring structure using the contact portion spring portion 93 achieves more reliable contact (connection) between the contact portion 94 of the contact 33 and the conductor 8 of the sheet sensor 4. In addition, a relatively large force for pulling out the sheet sensor 4 from between the first facing portion 43 and the second facing portion 65 of the housing 31 may be applied to the sheet sensor 4. In this case, since the contact portion 94 can be displaced in the second direction D2 away from the conductor 8, it can be prevented from being caught by the sheet sensor 4. Therefore, when the sheet sensor 4 needs to be disconnected from the first connector 21, a smooth disconnecting operation of the sheet sensor 4 can be realized. In addition, the contact portion 94 can be displaced in the first direction D1 and the second direction D2 in a state where the applied pressure is applied from the contact portion spring portion 93. Thereby, each contact part 94 can be displaced according to the thickness of the sheet sensor 4, the dimensional tolerance of the first connector 21, and the like. As a result, individual differences can be suppressed in the contact state between the contact portion 94 and the conductor 8 of the sheet sensor 4. As described above, the sheet sensor 4 can be smoothly disconnected from the first connector 21 as necessary while achieving reliable contact (conduction) between the conductor 8 of the sheet sensor 4 and the contact portion 94 of the contact 33. The conflicting effects can be realized by the first connector 21.

  Further, according to the monitoring device 1, the LED 35 is connected to the electric wires 29 c and 29 d for the LED 35 while being held in the housing 31. With this configuration, information such as the operation state of the first connector 21 and the sheet sensor 4 around the first connector 21 can be visually and clearly displayed using the LED 35 of the first connector 21. More specifically, when a signal is transmitted from the main body 6 to the LED 35 via the electric wires 29c and 29d, the LED 35 can emit light corresponding to the signal.

  Further, according to the monitoring device 1, the contact 33 includes a contact 33 a that can contact the first conductor 8 a of the sheet sensor 4 and a contact 33 b that can contact the second conductor 8 b of the sheet sensor 4. Yes. The electric wire 29a is in contact with the contact 33a, and the electric wire 29b is in contact with the contact 33b. According to this configuration, the number of poles of the first connector 21 can be made plural. As a result, the amount of information that the first connector 21 can transmit to the main body 6 can be increased.

  Further, according to the monitoring device 1, the second part 31 b of the housing 31 is connected to the first part 31 a of the housing 31 so as to be rotatable around the support shafts 50 and 50. According to this configuration, the housing 31 has a seesaw structure. With such a configuration, for example, by performing an operation in which an operator picks the first portion 31a and the second portion 31b, an interval between the first facing portion 43 and the second facing portion 65 is easily achieved. Can be expanded. Therefore, the worker can more easily perform the work of connecting the sheet sensor 4 to the first connector 21. Further, the contact 33 and the LED 35 are accommodated together in the first portion 31 a of the housing 31. That is, the members connected to the electric wires 29 are accommodated together in the first portion 31 a of the housing 31. Thereby, the structure of the 2nd part 31b of the housing 31 can be made simpler. As a result, the configuration of the first connector 21 can be further simplified.

  Further, according to the monitoring device 1, the first facing portion 43 and the second facing portion 65 of the housing 31 are pressed against each other by the housing spring portion 34 with the sheet sensor 4 interposed therebetween. Then, the conductor 8 of the sheet sensor 4 sandwiched between the housings 31 contacts the contact portion 94 of the contact 33. Moreover, the contact part 94 is pressurized toward the 1st direction D1 by the spring part 93 for contact parts. By such a two-stage spring structure by the cooperation of the housing spring portion 34 and the contact portion spring portion 93, more reliable contact (connection) between the contact portion 94 of the contact 31 and the conductor 8 of the sheet sensor 4 is achieved. Is achieved.

  Further, according to the monitoring device 1, the LED 35 is configured to be able to realize different light emission modes depending on the power supplied from the main body 6. According to this configuration, the LED 35 can realize various light emission modes by controlling the main body 6. Thereby, the 1st connector 21 can display information, such as an operation state of the sheet sensor 4 around the electrical connector unit 5, visually more clearly.

  Although a plurality of embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments. The present invention can be variously modified within the scope of the claims. For example, the following modifications may be made.

  (1) In the above-described embodiment, the contact portion spring portion 93 of the contact 33 has been described as an example in which the contact portion spring portion 93 is formed so as to swell in the drawing direction D4 opposite to the insertion direction D3.

In the following, the configuration different from the above embodiment will be mainly described, and the same reference numerals are given to the same configuration as the above embodiment, and the detailed description will be omitted.

  A middle portion of the base portion 91A of the contact 33A has a shape folded toward the insertion direction D3. The contact portion spring portion 93A extends from the base portion 91A and has a shape that swells in the insertion direction D3. Even in such a configuration, the smooth insertion operation and the drawing operation of the sheet sensor 4 with respect to the first facing portion 43 and the second facing portion 65 can be prevented from being disturbed by the contact 33.

  (2) In the above-described embodiment, the contact 33 and the contact portion spring 93 are integrally formed in the contact 33 as an example. However, this need not be the case. For example, as shown in FIG. 19, the contact portion 94B and the contact portion spring portion 93B may be formed of separate members. In this case, for example, the contact portion 94B is formed at the tip of the contact 33B. The contact 33B is pressurized in the first direction D1 by a contact portion spring portion 93B such as a coil spring. The contact 33B is connected to a corresponding electric wire (not shown in FIG. 19). Further, the edge of the base end portion of the contact 33B is received by the contact hole 45B of the first portion 31aB, thereby preventing the contact 33B from coming off from the first portion 31aB.

  (3) In the above-described embodiment, the first portion 31 a and the second portion 31 b of the housing 31 can be rotated using the support columns 47 and 47, the support shafts 50 and 50, and the support columns 68 and 68. The connected form has been described as an example. However, this need not be the case. For example, as shown in FIG. 20, the first portion 31aC and the second portion 31bC of the housing 31C may be rotatably connected via the bridging portion 100. The bridging portion 100 is an element of the housing 31C. For example, the bridging portion 100 is disposed at an intermediate portion of the housing 31C in the length direction X1. One end portion of the bridging portion 100 is connected to the first portion 31aC via the support shaft 101 so as to be relatively rotatable. The other end portion of the bridging portion 100 is connected to the second portion 31bC via the support shaft 102 so as to be relatively rotatable. The housing spring portion 34C is, for example, a coil spring.

  (4) Further, instead of the housing 31, for example, as shown in FIG. 21, a housing 31D formed in a V shape in a side view may be used. The first portion 31aD and the second portion 31bD of the housing 31D are connected to each other via a support shaft 103 so as to be rotatable. The support shaft 103 is connected to the rear end portion of the first portion 31aD and the rear end portion of the second portion 31bD. The housing spring portion 34D is disposed between the first portion 31aD and the second portion 31bD and functions as a tension spring. Thereby, the spring part 34D for housing provides the force which makes the 1st opposing part 43 of 1st part 31aD and the 2nd opposing part 65 of 2nd part 31bD approach mutually.

  (5) Moreover, in the above-mentioned embodiment, the form in which the sheet sensor 4 is used as the connected member has been described as an example. However, this need not be the case. For example, a flexible flat cable (FFC), a flexible printed circuit (FPC), or a circuit board having no flexibility may be used as the connected member. Even when these members to be connected are extremely thin, the contact 33 can contact the conductor of the members to be connected with a sufficient contact pressure, and when a pulling load of a predetermined value or more acts on the members to be connected, the first Smooth disconnection of the connected member from the connector 21 can be achieved.

  (6) Moreover, in the above-mentioned embodiment, the 1st opposing part 43 and the 2nd opposing part 65 demonstrated as an example the form where all are flat surfaces. However, this need not be the case. For example, fine irregularities may be provided on at least one of the first facing portion 43 and the second facing portion 65. By setting the uneven shape, the magnitude of the force with which the first facing portion 43 and the second facing portion 65 sandwich the member to be connected can be adjusted.

  (7) Moreover, in the above-mentioned embodiment, the form using a coil spring as the spring part 34 for housings was demonstrated to the example. However, this need not be the case. For example, the housing spring portion may be a spring other than a coil spring.

  (8) Further, in the above-described embodiment, the configuration in which the main body 6 is used as an electrical device connected to the electrical connector unit 5 has been described as an example. However, this need not be the case. For example, as an electrical device connected to the electrical connector unit 5, a device used for treatment other than artificial dialysis may be employed.

  (9) Moreover, although the above-mentioned embodiment demonstrated an example of the light emission aspect of LED35 of the 1st connector 21, it does not need to be this way. The mode of light emission control of the LED 35 by the control of the main body 6 may be set as appropriate.

  (10) Further, in the above-described embodiment, an example in which the housing spring portion 34 is provided has been described. However, this need not be the case. For example, the housing spring part 34 may not be provided. In this case, for example, the first portion 31 a and the second portion 31 b of the housing 31 are fixed to each other so that the gap between the first facing portion 43 and the second facing portion 65 is approximately the same as the thickness of the sheet sensor 4. The Further, the entire housing 31 may be an integrally molded product.

  (11) In the above-described embodiment, an example in which the second connector 23 is a USB connector has been described. However, this need not be the case. For example, the second connector 23 may be a connector other than a USB connector. For example, the second connector may have a configuration in which the electric wire 29 and the circuit board of the main body 6 are directly connected by solder or the like.

  (12) Moreover, in the above-mentioned embodiment, the electrical connector unit 5 demonstrated to the example the form used for the medical monitoring apparatus 1. FIG. However, this need not be the case. For example, the electrical connector unit 5 may be used for devices other than medical devices.

  The present invention can be widely applied as an electrical connector unit.
