Technical Field

[0001] The present invention relates to the technical field of connectors, and more particularly to an encapsulation structure of a gold finger connector. Background Art

[0002] For existing gold finger connectors, the contact parts mostly adopt a structure of being inserted from the tail. After wiring at the tail, there are through holes during plastic encapsulation, which will cause glue leakage during the plastic encapsulation process. Usually, it is necessary to add plugging parts to avoid the problem of glue leakage, which increases the investment in plugging parts. The present invention can complete glue encapsulation without adding plugging parts, reducing development investment, product cost, and process steps. Summary of the Invention

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following further describes the present invention in conjunction with embodiments. The described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

[0019] Embodiment:

[0020] As Figure 1 and 2As shown in the figure, a packaging structure of a gold finger connector includes an insulator 1 and at least a pair of contact members 2, which can be set according to actual needs at most, such as 8 pairs of contact members 2 or 10 pairs of contact members 2, etc. When there are multiple pairs of contact members 2, each pair of contact members 2 is independent of each other. An installation cavity is provided in the insulator 1, and the contact members 2 are fixedly arranged in the installation cavity. Installation openings 17 for installing the contact members 2 are formed on the side wall of the installation cavity. The number of the installation openings 17 corresponds to the number of the contact members 2 one by one. The wiring terminals 9 of the contact members 2 penetrate and extend out of the installation openings 17 and are connected to a cable 4 arranged outside the installation cavity. After the contact members 2 and the cable 4 are connected, the whole is subjected to plastic encapsulation to form a plastic encapsulated body 3. Among them, insulating partitions 7 for separating and insulating a pair of contact members 2 are provided on the side wall of the installation cavity. Here, the insulating partitions 7 are provided on both sides of the side wall of the installation cavity, and the external insulating partitions 7 are provided all the way to the end of the wiring terminal 9 of the contact member 2 to prevent short circuit of two mutually cooperating contact members 2. At the same time, the part of the contact member 2 extending out of the installation opening 17 can also be in tight fit contact with the insulating partition 7. The contact member 2 is provided with a bending portion for blocking the installation opening 17.

[0021] In this embodiment, the insulator 1 is provided with an insertion opening 5 communicating with the installation cavity at the insertion end 8 of the contact member 2. Fixing openings 6 communicating with the installation cavity are provided on the upper and lower sides of the insertion opening 5. The insertion ends 8 of a pair of mutually cooperating contact members 2 are fixed in the fixing openings 6. Here, the insertion opening 5 is mainly used for the insertion of the terminal during insertion and for inserting with the contact member 2. In addition to fixing the insertion end 8 of the contact member 2, the fixing opening 6 also has a function of playing a certain auxiliary role when the inserted terminal is inserted into the insertion opening 5. It should be noted here that when the insertion end 8 of the contact member 2 is fixed in the fixing opening 6, a certain distance is reserved in the fixing opening 6 to realize the positioning part for auxiliary fixing of the inserted terminal.

[0022] In this embodiment, the contact member 2 is provided with oppositely arranged connecting bending portions 10 on the side close to the insertion end 8. The distance between the connecting bending portions 10 of a pair of mutually cooperating contact members 2 is less than the height of the insertion opening 5. The contact member 2 is provided with a fixing portion 11 on the side close to the wiring terminal 9. The fixing portion 11 is in tight fit with the side wall of the installation cavity. The function of the fixing portion 11 is to realize tight fit. The fixing portion 11 and the connecting bending portion 10 just cooperate with each other so that the contact member 2 realizes tight fit after installation.

[0023] Such as Figure 3 and 4As shown, in this embodiment, bosses 16 are provided on the side walls on both sides in the width direction of the mounting opening 17, and the distance between the top of the boss 16 and the top of the mounting opening 17 is equal to the thickness of the fixing portion 11 of the contact member 2. Sealing ribs 15 are provided on the left and right sides of the fixing portion 11 of the contact member 2, and the upper part of the boss 16 of the mounting cavity is sealed through the sealing ribs 15 and the top surface of the fixing portion 11.

[0024] In this embodiment, the bending portion is in a broken line shape, including a first bending portion 12, a second bending portion 14, and a packaging portion 13 provided between the first bending portion 12 and the second bending portion 14. The width of the packaging portion 13 is equal to the width of the mounting opening 17. Since the width of the mounting opening 17 is greater than the distance between the two bosses 16, the mounting opening 17 corresponding to the boss 16 is sealed through the packaging portion 13. The distance between the side portion of the boss 16 and the mounting opening 17 is equal to the thickness of the packaging portion 13.

[0025] The sealing of the mounting opening 17 is divided into two parts. That is, by providing bosses 16 on the side walls on both sides inside the mounting opening 17, and the height of the boss 16 is less than the height of the mounting opening 17, the sealing of the mounting opening 17 is divided into two parts, namely the mounting opening 17 above the boss 16 and the mounting opening 17 corresponding to the boss 16. The width direction of the mounting opening 17 above the boss 16 is sealed by a tight fit through the sealing ribs 15 provided on the left and right sides of the fixing portion 11 of the contact member 2, and the top surface of the mounting opening 17 above the boss 16 is sealed by a tight fit through the first bending portion; the width direction of the mounting opening 17 corresponding to the boss 16 is sealed by a tight fit through the width of the packaging portion 13. Since the width of the mounting opening 17 is greater than the distance between the two bosses 16, the packaging portion 13 can seal it; the bottom surface of the mounting opening 17 corresponding to the boss 16 is sealed by a tight fit through the second bending portion 14.

[0026] At the same time, the setting of the sealing ribs 15 can also save a part of raw materials and reduce the production cost.

[0027] The structure of the present invention is novel and has strong practicability; the contact member 2 of the present invention adopts a new stamping structure. At the same time, bosses 16 are added between the mounting openings 17 of the insulator 1, so that when the contact member 2 is installed from the mounting opening 17, the mounting opening 17 can be directly sealed by relying on the contact member 2. Then, when the cable 4 is connected to the wiring terminal 9 of the contact member 2, no new plugging parts need to be added during plastic encapsulation, which can not only reduce the assembly process and improve production efficiency, but also greatly reduce the production cost of the enterprise.

[0028] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
