Description

Deconcentrator plug shell, deconcentrator and monitor lead wire

Technical Field

The utility model relates to the technical field of medical equipment, in particular to a deconcentrator of a lead wire.

Background

Electrocardiographic monitoring devices typically use an electrocardiographic lead to acquire electrocardiographic signals of a patient. The electrocardiograph lead comprises branch lines, a deconcentrator and a main line, wherein one end of the main line is connected with electrocardiograph monitoring equipment, the other end of the main line is connected to the deconcentrator, the branch lines are multiple, one end of each branch line is connected with the deconcentrator, and the other end of each branch line is connected with an electrode joint for collecting electrocardiograph signals of a patient. Each branch line is communicated with the main line through the deconcentrator, so that the branch lines can transmit signals collected by the electrode connectors to the main line through the deconcentrator and then to the electrocardiograph monitoring equipment.

The deconcentrator comprises a plug and a socket, the main line is connected with the socket, and the branch line is connected with the plug. The plug includes a plug housing and a plug contact assembly including a plug signal contact and a plug ground contact. The receptacle includes receptacle signal contacts and receptacle ground contacts. After the plug and the socket are inserted, the socket grounding contact is in conductive contact with the plug grounding contact.

In the existing wire-lead wire deconcentrator, the socket is mostly flat, the socket grounding contact is positioned on one side of the thickness direction of the socket, the socket grounding contact is usually in conductive contact with one side of the plug grounding contact, and in order to enable the socket grounding contact to be in stable contact with the plug grounding contact, the socket grounding contact usually comprises an elastic contact arm, and the elastic contact arm is in conductive contact with the plug grounding contact after elastic deformation. Because the plug contact assembly extends out of the plug shell, the elastic contact arm can easily cause the plug contact assembly to deflect relative to the plug shell after applying an acting force to the plug contact assembly, and adverse effects are caused on the opposite insertion of the plug and the socket. In addition, because the plug grounding contact piece in the plug contact assembly is exposed, after the plug and the socket are oppositely inserted, the plug grounding contact piece is closer to the butt joint surface of the plug and the socket, the insulating property is poor, and the discharge test passing rate is low.

The plug section 425 may be understood as a portion for mating with the socket 5.

The insulating housing 41 and the insulating support plate 417 are made of insulating material, and the plug housing further includes an extended insulating plate 418, the extended insulating plate 418 covering one end of the accommodation groove near the housing base 412.

The jack 411 includes a combination section 4111 and a housing base section 4112, with the flip 413 enclosing at least a portion of the combination section 4111 with the housing base 412. In some embodiments, all of the composite section 4111 is enclosed by the flip 413 and the housing base 412. The aperture of the end of the combined segment 4111 remote from the housing base segment 4112 is a spur outlet 4113 for leading out a spur. The swing axis of the flip 413 is at the junction of the combination section 4111 and the housing base section 4112. In some other embodiments, the insulating housing 41 may be a unitary structure, such as a plug assembly integrally inserted into the insulating housing, where the flip 413 is not required; in addition, the insulating shell can adopt a split two-piece buckling structure.

The cover 413 has a pressing surface 4131 for pressing the portion of the header contact assembly 42 in the combination segment 4111, and by pressing the header contact assembly 42, the stability of the header contact assembly 42 can be improved. It should be noted that, unless otherwise specified, the pressing described in the present application is not limited to direct contact pressing, but may be indirect pressing, such as a pad, a bushing, or the like, between the pressing surface 4131 and the header contact assembly 42.

Specifically, in one embodiment, referring to fig. 3 to 6, the plug contact assembly 42 includes a tail 424 covering the junction between the branch line 3 and the plug contact assembly 42, the tail 424 extends out of the receptacle 411, and the pressing surface 4131 is pressed against the outer peripheral surface of the tail 424.

In some other embodiments, the pressing surface 4131 of the flip 413 may also press directly against the header ground contact 422.

In order to improve the stability of the flip cover 413 after being buckled with the shell base 412, the insulating housing 41 includes at least two locking structures, and the locking structures include a spring arm 414 and a clamping structure 415 corresponding to the spring arm 414. The same locking structure: one of the spring arm 414 and the holding structure 415 is disposed on the flip cover 413, and the other is disposed on the case base 412, and the spring arm 414 can elastically deform to enable the holding structure 415 to clamp the corresponding spring arm 414 after the flip cover 413 is covered, so as to limit the flip cover 413 to be opened.

In some embodiments, referring to fig. 3, 6 and 7, the spring arm 414 of the at least one locking structure is a first spring arm 4141, the spring arm 414 of the at least one locking structure is a second spring arm 4142, and the first spring arm 4141 and the second spring arm 4142 are arranged at intervals in the extending direction of the swing axis.

The retaining structure 415 corresponding to the first spring arm 4141 is a first retaining structure, and the retaining structure 415 corresponding to the second spring arm 4142 is a second retaining structure. In the process of buckling the flip 413 and the shell base 412, the elastic arm 414 contacts with the clamping structure 415 and elastically deforms under the action of the clamping structure 415, the free end of the elastic arm 414 swings, after the clamping structure 415 clamps the elastic arm 414, the elastic arm 414 resets, and the clamping structure 415 is in a state of clamping the elastic arm 414. When the spring arms 414 are in contact with the retaining structure 415 and elastically deformed, the free ends 4144 of the first spring arms 4141 and the free ends 4145 of the second spring arms 4142 are moved toward or away from each other, i.e., the free ends 4144 of the first spring arms 4141 and the free ends 4145 of the second spring arms 4142 move toward or away from each other. When the first elastic arm 4141 and the second elastic arm 4142 are deformed, the free end 4144 of the first elastic arm 4141 and the free end 4145 of the second elastic arm 4142 are close to each other or far away from each other, so that the whole stress of the flip 413 is balanced, and the flip 413 is less prone to shaking and is less prone to being opened by mistake.

In addition to the above manner, in some other embodiments, the spring arm 414 may also be provided with a protrusion, and the retaining structure 415 is a slot adapted to the protrusion. Alternatively, in some other embodiments, the spring arm 414 may have a slot or a protrusion, and the shell base 412 may have a corresponding protrusion and slot.

Further, in an embodiment, referring to fig. 6 and 7, the protrusion is elongated, and the extending direction of the protrusion is consistent with the extending direction of the jack 411, and the spring arm 414 extends in the buckling direction of the flip cover 413 and the shell base 412. In some other embodiments, the protrusions may also be cylindrical.

Specifically, the first spring arm 4141 and the second spring arm 4142 are symmetrically disposed. The spring arm 414 extends toward the side of the cover 413 facing the case base 412, and the spring arm 414 moves toward the case base 412 along with the cover 413 when the cover 413 is engaged.

In an embodiment, referring to fig. 6 and 7, the first spring arm 4141 and the second spring arm 4142 are disposed on the flip 413, and the first spring arm 4141 is located on one side of the flip 413 in the direction of extending the swing axis, and the second spring arm 4142 is located on the other side of the flip 413 in the direction of extending the swing axis.

In other embodiments, the spring arms 414 may be an odd number, such as two for the first spring arm 4141 and one for the second spring arm 4142. In some other embodiments, the spring arm 414 may also be disposed in the middle of the flip 413 in the direction of extension of the swing axis. In other embodiments, spring arms 414 may be disposed on the housing base 412 and retaining structures 415 may be disposed on the flip cover 413.

In some embodiments, referring to fig. 6 and 7, the housing base 412 has a first housing base guide surface 4121 and a second housing base guide surface 4122, and the flip cover 413 has a first flip cover guide surface 4132 and a second flip cover guide surface 4133. The first housing base guide surface 4121 is opposite or opposed to the second housing base guide surface 4122. During the engagement of the flip cover 413 with the housing base 412, the first housing base guide surface 4121 contacts and moves relative to the first flip cover guide surface 4132 during the elastic deformation of the first resilient arm 4141 and the second resilient arm 4142, and the second housing base guide surface 4122 contacts and moves relative to the first flip cover guide surface 4132 during the elastic deformation of the first resilient arm 4141 and the second resilient arm 4142 to guide the swing of the flip cover 413 about the swing axis. In the process of buckling the flip 413 and the shell base 412, the elastic arm 414 needs to be elastically deformed, so that the flip 413 is stressed and easily swings, and the flip 413 is enabled to be buckled with the shell base 412 accurately by guiding the flip 413, so that the flip 413 is not easy to be blocked.

Further, the cover 413 includes a cover guide groove 4134, the cover base 412 includes a cover base guide block 4123, and after the cover 413 is buckled with the cover base 412, the cover base guide block 4123 is inserted into the cover guide groove 4134, the first cover base guide surface 4121 is located on the cover base guide block 4123, the first cover guide surface 4132 is located in the cover guide groove 4134, and is formed by a groove wall surface of the cover guide groove 4134.

Specifically, there are two case base guide blocks 4123, a first case base guide surface 4121 is provided on one case base guide block 4123, a second case base guide surface 4122 is provided on the other case base guide block 4123, there are two flip guide grooves 4134, a first flip guide surface 4132 is provided in one flip guide groove 4134, and a second flip guide surface 4133 is provided in the other flip guide groove 4134, formed by the groove wall surface of the other flip guide groove 4134.

Specifically, the flip guide groove 4134 is a groove having an L-shaped cross section. In some other embodiments, the cross-section of the flip guide slot 4134 may be U-shaped, C-shaped, etc.

The case base guide block 4123 has a case base inclined surface 4124 thereon, and one side groove wall surface of the flip guide groove 4134 is an inclined groove wall surface 4135 that is fitted to the case base inclined surface 4124, and after the flip 413 is completed to be engaged with the case base 412, the case base inclined surface 4124 is opposed to the inclined groove wall surface 4135 in the extending direction of the insertion hole 411.

Further, referring to fig. 6 and 7, the first spring arm 4141 and the second spring arm 4142 are disposed on the flip 413, and the first spring arm 4141 is located on one side of the flip 413 in the direction of extending the swing axis, and the second spring arm 4142 is located on the other side of the flip 413 in the direction of extending the swing axis. The two side surfaces of the shell base 412 in the extending direction of the swing axis are a first side surface 4125 and a second side surface 4126, the clamping structure 415 corresponding to the first elastic arm 4141 is located on the first side surface 4125, and the clamping structure 415 corresponding to the second elastic arm 4142 is located on the second side surface 4126.

The first elastic arm 4141 can deform in a direction away from the second elastic arm 4142 during the buckling process of the flip 413, so as to be engaged by the corresponding clamping structure 415. The second spring arm 4142 can deform in a direction away from the first spring arm 4141 during the buckling process of the flip 413, so as to be engaged by the corresponding clamping structure 415. The first flip guide surface 4132 is opposite the second flip guide surface 4133.

In the above embodiment, after the spring arm 414 engages with the holding structure 415, the spring arm 414 returns to the state before deformation. In some other embodiments, the spring arm 414 may be in a deformed state after engaging the retaining structure 415.

In one embodiment, referring to fig. 4, 6 and 7, the cover 413 is injection molded with the housing base 412, and a thinned movable connecting portion 416 is integrally formed at a connecting position of the cover and the housing base 412. In some other embodiments, the flip 413 may also be coupled to the housing base 412 by a hinge structure, such as by a hinge, and may be coupled by a hinge.

Specifically, there are two thinning movable connecting portions 416 between the lid 413 and the case base 412, and the two thinning movable connecting portions 416 are arranged at intervals in the direction in which the swing axis extends.

To further enhance the insulative properties of the header 4, in one embodiment, referring to fig. 3 and 5, the mesh tail 424 extends to the periphery of the header ground contact 422 and to the outlet of the housing base section 4112. The outlet of the housing base section 4112 allows the plug contact assembly 42 to extend into the mating section receiving groove 4171. Such that one end of the net tail 424 extends beyond the spur outlet 4113 of the jack 411 and the other end is inserted into the housing base section 4112 and extends to the outlet of the housing base section 4112.

The receptacle 411 of the housing base 412 has a stop surface 4114 at the outlet of the housing base section 4112, the stop surface 4114 facing away from the mating section receiving slot 4171. After the plug contact assembly 42 is inserted into the jack 411, one end of the tail 424 extends out of the jack 411, and the other end of the tail 424 abuts against the stop surface 4114, so that even if the branch line 3 is bent, the tail 424 can protect the branch line 3 from being broken. The stop surface 4114 is in stop engagement with the web tail 424 in the direction of extension of the receptacle 411. After the plug contact assembly 42 is inserted into place, the stop surface 4114 is stopped with one end surface of the net tail 424, and then the flip 413 is pressed, so that the flip 413 presses the net tail 424, and the plug contact assembly 42 can be fixed.

Because the net tail 424 is made of insulating material, the joint between the flip cover 413 and the shell base 412 is located between the stop surface 4114 and the branch lead-out port 4113, and the plug contact assembly 42 is not easily broken down, so that the insulating performance of the plug 4 is better.

In one embodiment, the plug 4 assembly process is as follows:

When the flip 413 needs to be opened, the flip 413 can be flipped open by prying the spring arm 414 to deform the spring arm 414, and separating the spring arm 414 from the holding structure 415.

In one embodiment, referring to fig. 3 and 5, since the free end 4137 of the flip cover and the shell base 412 enclose the branch outlet 4113 of the jack 411, during the process of fastening the flip cover 413 and the shell base 412, a force for moving the plug contact assembly 42 into the jack 411 can be applied to the plug contact assembly 42, so that the stop surface 4114 always keeps in contact with the end surface of the net tail 424, and thus, the position of the plug contact assembly 42 relative to the shell base 412 can be maintained during the process of fastening the flip cover 413 and the shell base 412.

In one embodiment, the web tail 424 may be made of two materials of different hardness, such as a softer material for the portion at the branch outlet 4113 through the receptacle 411 and a harder material for the remainder in the receptacle 411.
