Description

Technical Field

[0001] This utility model relates to the field of connector fixing technology, specifically to an injection molding structure that enhances the connection strength of the connector inner mold. Background Technology

[0002] Although existing connector fixing components are constantly being innovated and developed to basically meet people's needs, there is still room for improvement.

[0003] For example, patent document CN222851716U discloses an injection-molded structure for enhancing the connection strength of the connector's inner mold. It includes a connector body consisting of a connector base and an inner mold connected to the connector base via injection molding. Terminals are enclosed inside the inner mold, protruding through a slot at the bottom of the connector base. A through-hole is provided at the engagement position between the connector base and the head of the inner mold. The two sides of the inner mold are connected through the through-hole, which also secures the connector base. This solves the problems of low connection strength, easy cracking and detachment, and short service life of internal structural components in existing medical monitoring equipment connectors.

[0004] The aforementioned injection molding connection mechanism forms a limiting position on the male and female connectors through injection molding, preventing loosening due to connector aging. However, its overall slotting is located on a single female connector, resulting in weak connection between the limiting part and the male connector after injection molding, affecting the actual fixing effect. Therefore, an injection molding structure that enhances the connection strength of the connector's inner mold is needed to solve the above problems. Utility Model Content

[0005] In order to overcome the above-mentioned technical problems, the purpose of this utility model is to provide an injection molding structure that enhances the connection strength of the inner mold of the connector, so as to solve the problem mentioned in the background art that the injection molding connection mechanism forms a limit on the male and female connectors by injection molding to avoid loosening due to connector aging. However, the overall slot is located on a single female connector, resulting in weak connection between the limit part and the male connector after injection molding, which affects the actual fixing effect.

[0006] This utility model provides the following technical solution: an injection molding structure that enhances the connection strength of the connector inner mold, including a connecting mechanism, wherein the connecting mechanism includes a male head and a female head that are plugged into each other; It also includes an auxiliary mechanism, which includes a first inlet on the male head and a second inlet on the female head; The openings of the first injection port and the second injection port are L-shaped and are symmetrically attached to each other to form an injection molding chamber; In addition, several raised textures formed by the protrusions on the surfaces of the first and second injection ports.

[0007] To achieve the above technical solution, the first and second injection ports are symmetrically aligned, and protrusions on the inner surfaces of the first and second injection ports are used to form inserts. This allows the injection molded part to be fixedly positioned in the first and second injection ports after cooling. Compared with the prior art, this device has a better connection effect and ensures the bonding effect between the injection molded part and the male and female heads.

[0008] As a further improvement to this utility model, the auxiliary mechanism is two in number and is symmetrical along the X-axis midline of the male and female heads.

[0009] The above technical solution ensures that the injection molded part is symmetrical on the male and female heads, thus improving the stability of the fixation.

[0010] As a further improvement to this utility model, the depth of the first injection port and the second injection port is at least half the thickness of the female or male head.

[0011] The above technical solution ensures the strength of the injection molded parts.

[0012] As a further improvement to this utility model, a plug rod and a plug sleeve are respectively connected to the opposite positions of the inner walls of the first injection port and the second injection port.

[0013] The above technical solution improves the effective contact area between the inner walls of the first and second injection ports and the injection molded part.

[0014] As a further improvement to this utility model, the sleeve has an inner cavity, and the insert rod extends and is inserted into the inner cavity of the sleeve.

[0015] The above technical solution utilizes the fitting effect of the insert rod and the sleeve to improve the tightness of the insertion and removal of the male and female connectors.

[0016] As a further improvement to this utility model, recessed holes are uniformly formed on the surface of the insert.

[0017] The above technical solution facilitates the injection of plastic into the recessed hole, increasing the fixing strength of the insert and the sleeve.

[0018] The technical effects and advantages of this utility model are as follows: 1. This utility model adopts the symmetrical alignment of the first injection port and the second injection port, and the protrusions on the inner surfaces of the first injection port and the second injection port form an insert rod, so that the injection molded part is fixedly limited in the first injection port and the second injection port after cooling.

[0019] 2. Compared with the prior art, the connection effect of this device is better, ensuring the bonding effect between the injection molded part and the male and female heads. Attached Figure Description
