Description

Technical Field

[0001] The utility model relates to the field of medical device connectors, and particularly to an internal contactor of a connector with a limiting structure. Background Art

[0002] Medical monitoring devices are precision medical instruments used to digitally present various index data of patients' bodies. For example, an electrocardiogram monitor has functions such as acquisition, storage, intelligent analysis and early warning of electrocardiogram information. Such precision monitoring devices rely on various connectors to achieve data transmission, and the connectors must have the characteristics of anti-interference and strong connection stability.

[0003] In the prior art, the functional elements inside the data connectors of such monitoring devices are connected to the contact terminals by extremely thin pins, and a connection seat or a connection shell is arranged outside the contact terminals. After the connection seat and other structures are fixed to the contact terminals, due to internal stress after long-term use, the terminals are separated from the shell. At this time, due to the displacement of the contact terminals, the connection of the extremely thin pins will be affected.

[0004] In view of this, the technical solution of the present application proposes an internal contactor of a connector with a limiting structure, which adopts a barb structure integrated with the contact terminal. When there is a contact terminal in the connection seat, due to the limitation of the barb structure, the connection seat cannot move in the reverse direction, thus playing a role in preventing detachment. The overall structure is simple, without changing the existing shape of the shell, and the barb structure is a simple and tiny convex structure integrally formed with the contact terminal, which is easy to process, manufacture and assemble. Summary of the Utility Model

[0005] The technical solution of the utility model aims to solve at least one of the technical problems in the related art to some extent. For this reason, the main purpose of the utility model is to provide an internal contactor of a connector with a limiting structure, aiming to solve the problems that the internal part of the data connector used in the monitoring device in the prior art is easily detached, resulting in frequent failures, and the connection seat cannot form a high-strength fixation with the contact terminal.

[0006] To achieve the above purpose, the utility model provides an internal contactor of a connector with a limiting structure, including a connector body, and a contactor assembly and a functional element arranged in the connector body.

[0007] The contactor assembly includes a contact head, and a connection sleeve connected to one end of the contact head. A reverse-stop barb is arranged between the contact heads.

[0008] One end of the acting element is provided with a contact pin, the connecting sleeve is connected to the contact pin, an adapter is externally encapsulated on the contact head, and the inner wall of the adapter contacts the anti-retreat barbs, and the contact head prevents the adapter from loosening through the anti-retreat barbs.

[0009] As a further solution of the present invention, a limiting platform is formed at the joint position of the connecting sleeve and the contact head, and the limiting platform fits against the bottom of the adapter.

[0010] As a further solution of the present invention, the connector body further includes an inner mold wrapped around the contactor assembly and the acting element, and the inner mold is an integrally injection-molded insulating rubber shell structure.

[0011] As a further solution of the present invention, an outer cover is wrapped around the outside of the inner mold.

[0012] As a further solution of the present invention, the number of the anti-retreat barbs provided on the connecting sleeve is at least two, the anti-retreat barbs are arranged in a circumferentially arranged outwardly expanding structure, and the outward expansion direction is opposite to the direction in which the adapter is disengaged.

[0013] As a further solution of the present invention, the anti-retreat barbs and the contact head and the connecting sleeve are an integrally formed copper joint structure.

[0014] The beneficial effects of the present invention are as follows:

[0015] The internal contactor of the connector with a limiting structure proposed by the present invention realizes that the entire contactor assembly does not generate displacement after being assembled with the adapter through the anti-retreat barbs arranged on the surface of the contact head, which not only prevents the separation of the contact head and the adapter, but also avoids the disconnection of the connecting sleeve from the contact pin due to displacement, enhances the connection stability, and extends the service life of the entire connector. The overall structure is simple, without complex fixing structures, and only an integrally formed small convex barb is arranged on the surface of the contact head, which is easy to process.

Description of the reference numerals of the main components / assemblies

[0023] Label Name Label Name 1 Connector body 112 Contact head 10 Inner mold 12 Connection base 11 Contactor assembly 13 External housing 110 Connection sleeve 14 Actuating element 1100 Limit platform 140 Contact pin 111 Anti-retreat barb Detailed implementation manners

[0024] Are as follows:

[0025] Please refer to the attached Figures 1 - 5 ,

[0026] The main structure includes a connector body 1, and a contactor assembly 11 and an acting element 14 arranged in the connector body 1. The contactor assembly 11 includes a contact head 112 and a connecting sleeve 110 connected to one end of the contact head 112. An anti-retreat barb 111 is provided between the contact heads 112. One end of the acting element 14 is provided with a contact pin 140, and the connecting sleeve 110 is connected to the contact pin 140. A connecting seat 12 is externally encapsulated on the contact head 112, and the inner wall of the connecting seat 12 is in contact with the anti-retreat barb 111. The contact head 112 prevents the connecting seat 12 from loosening through the anti-retreat barb 111.

[0027] The working principle is as follows:

[0028] The front end of the integrally formed anti-retreat barb 111 of the contact head 112 of the contactor assembly 11 is designed with a smooth slope, which is easy to be inserted under the guidance of the slope when the contactor assembly 11 is inserted forward. When the anti-retreat barb 111 enters the plastic housing of the connecting seat 12, the barb will pierce into the housing, but the contactor assembly 11 can still continue to slide forward under the guidance of the slope. At the same time, it is precisely because the barb has pierced into the inside of the housing that when the metal contactor has a reverse force, the barb will generate a huge frictional force with the inside of the plastic housing, effectively preventing the contactor from retreating from the housing. The effect that the metal contactor can only move forward and cannot move backward is achieved.

[0029] In a preferred embodiment of the present utility model: a limiting platform 1100 is formed at the joint position of the connecting sleeve 110 and the contact head 112, and the limiting platform 1100 fits against the bottom of the connecting seat 12.

[0030] The limiting platform 1100 prevents the contact head 112 from moving to the other side, and cooperates with the anti-retreat barbs 111 to fix the entire contactor assembly 11 firmly to the connection base 12.

[0031] A preferred embodiment of the present utility model: The connector body 1 further includes an inner mold 10 covering the contactor assembly 11 and the acting element 14. The inner mold 10 is an integrally injection-molded insulating plastic shell structure. An outer cover 13 is provided outside the inner mold 10.

[0032] The inner mold 10 covered by the outer cover 13 has the functions of isolating the outside and insulating. And because the internal connection is stable in this solution, the inner mold 10 can be set in the form of injection molding.

[0033] A preferred embodiment of the present utility model: The number of the anti-retreat barbs 111 provided on the connection sleeve is at least 2. The anti-retreat barbs 111 are arranged in a circumferentially arranged outward-expanded structure, and the outward expansion direction is opposite to the detachment direction of the connection base 12.

[0034] The anti-retreat barbs 111 can be a ring-shaped anti-retreat structure arranged around the contact head 112, which expands outward to one side.

[0035] A preferred embodiment of the present utility model: The anti-retreat barbs 111, the contact head 112 and the connection sleeve 110 are an integrally formed copper joint structure.

[0036] The entire contactor assembly 11 is an integrally formed copper contact structure. The anti-retreat barbs 111 are easy to process and form, and there is no need to set up a complex fixing structure.

[0037] The above are only the preferred embodiments of the technical solutions of the present utility model, and do not limit the patent scope of the technical solutions of the present utility model. Any equivalent structural transformation made under the inventive concept of the technical solutions of the present utility model by using the specification and drawings of the technical solutions of the present utility model, or any direct / indirect application in other related technical fields shall be included in the patent protection scope of the technical solutions of the present utility model.
