Description

Technical Field

[0001] The utility model relates to the field of medical equipment connectors, in particular to an injection molding structure for enhancing the connection strength of an inner mold of a connector. Background Art

[0002] Medical monitoring equipment is a precision medical instrument used to present various indicators of the patient's body in a digital form. For example, an ECG monitor has the functions of collecting, storing, intelligently analyzing and warning ECG information. This type of precision monitoring equipment relies 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 internal structure of the connector used in the ECG monitoring equipment usually adopts a structure in which the internal terminal is wrapped by an injection mold. The injection mold is generally a thermoforming coating method, which is easy to shrink after molding and easy to fall off and crack during use. This unstable connection factor will also cause the problem of poor terminal contact.

[0004] In view of this, the present technical solution proposes an injection molding structure for enhancing the connection strength of the connector inner mold. By opening a through hole that can enhance the connection strength at the joint between the connecting seat and the injection molding inner mold, the connection stability between the inner mold and the connecting seat after injection molding is enhanced, eliminating problems such as cracking and falling off, and extending the service life of the connector. Utility Model Content

To this end, the main purpose of the utility model is to provide an injection molding structure for enhancing the connection strength of the inner mold of the connector, aiming to solve the problem that the connection strength of the internal structural parts of the medical monitoring equipment connector in the prior art is not high, easy to crack, fall off, and has a short service life.

[0006] To achieve the above-mentioned purpose, the utility model provides an injection molding structure for enhancing the connection strength of the inner mold of a connector, comprising a connector seat and a connector seat body composed of an inner mold connected to the connector seat by injection molding.

[0007] The inner part of the inner mold is covered with a terminal, and the terminal passes through a vacant space at the bottom of the connecting seat.

[0008] A through hole is provided at the joint position between the connection seat and the inner mold head, and the two sides of the inner mold are connected through the through hole to fix the connection seat.

[0009] As a further solution of the utility model, the connecting seat is further provided with a groove located near the through hole.

[0010] As a further solution of the utility model, a foot seat for fixing the root of the terminal is provided at the bottom of the connecting seat.

[0011] As a further solution of the present invention, an external cover shell is provided outside the inner mold.

[0012] As a further solution of the utility model, the number of the through holes at least opened on both sides of the connecting base is at least 8, and they are evenly distributed on both sides of the connecting base.

[0013] As a further solution of the utility model, the grooves are arranged on both sides of the connecting seat.

[0014] As a further solution of the present invention, the connecting seat is an integrally formed plastic insulating seat structure.

[0015] The beneficial effects of the utility model are as follows:

[0016] The utility model proposes an injection molding structure for enhancing the connection strength of the inner mold of the connector. Through the through hole opened on the foot seat, the inner mold is poured into the through hole during injection molding, and a connecting piece is formed after solidification, thereby strengthening the connection strength with the connecting seat. There is no need to set up a complicated fixing mechanism. High-strength connection and fixation can be achieved, and the service life is extended, and the problems of loosening and bursting are eliminated. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] as follows:

[0025] Please refer to the attached Figure 1-4 ,

[0026] The main structure includes a socket body 1 consisting of a connecting socket 10 and an inner mold 11 connected to the connecting socket 10 by injection molding. The interior of the inner mold 11 is covered with a terminal 110, and the terminal 110 passes through a vacant space set at the bottom of the connecting socket 10. A through hole 102 is opened at the joint position between the connecting socket 10 and the head of the inner mold 11. The two sides of the inner mold 11 are connected through the through hole 102 to fix the connecting socket 10.

[0027] Here’s how it works:

[0028] In order to prevent the inner mold 11 and the connecting seat 10 from being deformed or separated or bursting due to working heat after long-term use, through holes 102 are opened on the connecting seat 10 (opened at the joint position of the connecting seat 10 and the inner mold 11), so that when the inner mold 11 is injected, the semi-liquid plastic of the inner mold 11 will enter these through holes 102 and then solidify, so that the plastic of the inner mold 11 and the main body of the plastic shell form a whole, greatly strengthening the bonding strength between the connecting seat 10 and the inner mold 11. The method of enhancing the connection strength by punching and pouring can achieve high-strength connection without changing the injection molding process and the main structure.

[0029] A preferred embodiment of the present invention: the connection base 10 is further provided with a groove 101 located near the through hole 102 .

[0030] The provided groove 101 further allows the semi-liquid plastic (inner mold 11 ) to remain therein, and after solidification, a snap-fit ​​structure is formed, further strengthening the connection strength between the connection base 10 and the inner mold 11 .

[0031] A preferred embodiment of the present invention: a foot seat 103 for fixing the root of the terminal 110 is provided at the bottom of the connecting seat 10 .

[0032] The foot base 103 disposed at the bottom of the connection base 10 can fix and protect the base of the terminal 110 to prevent extrusion caused by excessive stress after injection molding.

[0033] A preferred embodiment of the present invention: an outer cover shell 2 is provided outside the inner mold 11 .

[0034] The external cover shell 2 serves as the outermost layer of protection for the entire internal structure.

[0035] In a preferred embodiment of the present invention, the number of the through holes 102 at least provided on both sides of the connecting base 10 is at least 8 and are evenly distributed on both sides of the connecting base 10 .

[0036] The eight through holes 102 evenly distributed on both sides of the connection base 10 help to balance the connection after injection molding and curing on both sides, and still maintain a high connection strength after long-term use.

[0037] A preferred embodiment of the present invention: the grooves 101 are arranged on both sides of the connecting base 10 .

[0038] Grooves 101 are formed on both sides of the connection base 10 . When the semi-liquid plastic solidifies in the grooves 101 , a strong buckle structure is formed.

[0039] In a preferred embodiment of the present invention, the connecting seat 10 is an integrally formed plastic insulating seat structure.

[0040] The connection base 10 is a component for plugging and connecting with an external plug-in device, and adopts an integrated plastic structure with high structural strength. After the terminal head passes through the bottom of the connection base 10 , it is located in the hole 100 .

[0041] The above are only preferred embodiments of the technical solution of the utility model, and do not limit the patent scope of the technical solution of the utility model. All equivalent structural changes made by using the contents of the technical solution description and drawings of the utility model under the conception of the technical solution of the utility model, or direct / indirect application in other related technical fields are included in the patent protection scope of the technical solution of the utility model.
