Description

Technical Field

[0001] The present invention relates to a connector inner frame, in particular to an integrated inner frame of a connector (such as C5), belonging to the technical field of electrical connection devices. Background Art

[0002] Connectors are a commonly used and indispensable component in electronic devices. The function of connectors is very simple: to build a bridge of communication between blocked or isolated circuits within a circuit, so that current can flow and the circuit can achieve its intended function.

[0003] At present, C5 connectors are mainly assembled structures, that is, the terminals are crimped first and then inserted into the C5 sleeve. The disadvantages of this method are obvious: too many processes and too many people. For example, the E-line terminals of C5 are different from the LN-line terminals. It takes two steps to make the terminals with a continuous strip, plus the sleeve-wearing process, which is three steps, and requires 3 people to complete. In order to improve efficiency and reduce personnel, one-piece copper feet must be used, which also lays the foundation for subsequent automation. There are also many units in the industry that are developing such products, but most of them have various problems. Some copper feet (i.e., inner frames) do not have a hole-like structure at the tail to hold the glue, so that the copper feet and the glue of the finished product after injection molding are easily separated by tension; some copper feet do not have a sealing step, which makes it easy to form a flash during injection molding and affect the appearance; some copper feet have skewed or uneven terminals, resulting in poor terminal hitting; and some copper feet have gaps between the terminals and the sleeve, and there will be glue flushing in the jack during injection molding. Therefore, a good C5 one-piece copper foot should avoid the above problems to ensure stable and controllable quality. Summary of the invention

[0004] The object of the present invention is to provide an integrated inner frame of a connector, which improves the tensile reliability and life of the connector and has reliable sealing capability.

[0005] In order to achieve the above technical purpose, the technical solution of the present invention is:

[0006] A connector integrated inner frame comprises an E-line terminal, an L-line terminal, an N-line terminal and a sleeve for installing the terminals, wherein the sleeve is provided with an E-line terminal hole, an L-line terminal hole and an N-line terminal hole, and the E-line terminal, the L-line terminal and the N-line terminal are respectively installed in the E-line terminal hole, the L-line terminal hole and the N-line terminal hole of the sleeve, and a sealing step is provided on the outer side of the sleeve, and the sealing step divides the sleeve into a sleeve front end and a sleeve rear end.

[0007] The E-line terminal, L-line terminal, and N-line terminal are respectively inserted into the E-line terminal hole, L-line terminal hole, and N-line terminal hole from the front end of the cover. The front end of the cover and the rear end of the cover are separated by a clearly defined sealing step. When the product is injected, the sealing step is tightly fitted with the mold to play a good sealing role and prevent flashing.

[0008] At the front end of the sleeve, outside the E-line terminal hole, L-line terminal hole, and N-line terminal hole, a sealing step is provided with a panel, and a plurality of glue holes are provided between the panel and the sealing step. In this way, the inner frame and the glue can be fixed together in all directions (the number is the same as the glue holes), which greatly improves the tensile reliability of the connector. Specifically, the glue holes are formed by a plurality of notches on the edge of the sealing step where the sealing step contacts the panel.

[0009] Preferably, there are three glue holes, one on each side of the E-line terminal hole, and one between the L-line terminal hole and the N-line terminal hole. In this way, the three glue holes are facing the parting surface of the cover, and side core pulling is not required when designing the cover mold, which not only simplifies the structure of the cover mold but also increases the life of the cover mold.

[0010] The end face of the enclosure is inclined, so that when the inner frame is impacted by high-pressure rubber in the mold, the impact force on all sides can be converted into an extrusion force on the inner frame forward. The extrusion force makes the sealing step contact the mold more closely, making the sealing ability of the inner frame more reliable.

[0011] In order to position the terminals and reduce the possibility of terminal glue punching, the E-line terminals, L-line terminals and N-line terminals are all provided with gaps, and the inner sides of the E-line terminal holes, L-line terminal holes and N-line terminal holes are all provided with limiting bosses. When the E-line terminals, L-line terminals and N-line terminals are inserted into the corresponding E-line terminal holes, L-line terminal holes and N-line terminal holes, the limiting bosses are inserted into the gaps. This not only plays a role in positioning the terminal position and ensuring the depth of the terminal hole, but also prevents the terminal from retreating due to external forces after the terminal is punched, causing problems such as the terminal hole being punched. In addition, due to the existence of the limiting boss, the gap on the terminal that is most likely to be punched is sealed, which greatly reduces the possibility of glue punching, and limiting the terminal will also reduce the occurrence of poor terminal punching.

[0012] The structure of the present invention enhances the tensile reliability of the connector, simplifies the structure of the cover mold, increases the life of the cover mold, enhances the tightness between the copper foot and the mold during injection molding of the C5 connector, effectively reduces the occurrence of flash, and effectively limits the terminal, reducing the phenomenon of glue punching, poor terminal punching, etc. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] like Figure 1-8 As shown, a connector integrated inner frame includes an E-line terminal 1, an L-line terminal 2, an N-line terminal 12 and a sleeve 3 for installing the terminals, wherein the sleeve 3 has an E-line terminal hole 11, an L-line terminal hole 15 and an N-line terminal hole 16, and the E-line terminal 1, the L-line terminal 2 and the N-line terminal 12 are installed in the E-line terminal hole 11, the L-line terminal hole 15 and the N-line terminal hole 16 of the sleeve 3 respectively. Fig. 9 As shown, the E-line terminal 1, the L-line terminal 2, and the N-line terminal 12 are all provided with a gap 14. Fig.10As shown, the inner sides of the E-line terminal hole 11, the L-line terminal hole 15, and the N-line terminal hole 16 are all provided with a limiting boss 8, and the limiting boss 8 is 0.2mm high. When the E-line terminal 1, the L-line terminal 2, and the N-line terminal 12 are inserted into the corresponding E-line terminal hole 11, the L-line terminal 15, and the N-line terminal hole 16 (that is, the E-line terminal 1 is inserted into the E-line terminal hole 11, the L-line terminal 2 is inserted into the L-line terminal hole 2, and the N-line terminal 12 is inserted into the N-line terminal hole 16), the limiting boss 8 is inserted into the gap 14. This not only plays a role in positioning the terminal position and ensuring the depth of the terminal hole, but also prevents the terminal from being affected by external forces and retreating after the terminal is punched, causing problems such as the terminal hole being punched. In addition, due to the existence of the limiting boss 8, the gap on the terminal that is most likely to be punched is sealed, which greatly reduces the possibility of punching, and the limiting of the terminal will also reduce the occurrence of poor terminal punching.

[0025] like Figure 6 As shown, a sealing step 7 is provided on the outer side of the sleeve 3. Figure 3 As shown, the sealing step 7 divides the cover 3 into a cover front end 9 and a cover rear end 10. The cover front end 9 and the cover rear end 10 are separated by a clearly defined sealing step 7. When the product is injected, the sealing step 7 fits tightly with the mold to play a good sealing role and prevent the occurrence of flashing.

[0026] At the front end 9 of the sleeve, outside the E-line terminal hole, the L-line terminal hole, and the N-line terminal hole, a panel 17 (such as Figure 1 , 4 As shown), there are a plurality of glue holes 4, 5, 6 between the enclosure 17 and the glue step 7, and the glue holes 4, 5, 6 are formed by a plurality of notches on the edge of the glue step 7 where the glue step 7 contacts the enclosure 17. Specifically, there are three glue holes (the present invention does not limit the number of glue holes), and the specific positions are: glue holes 5 and glue holes 6 are respectively provided on both sides of the E-line terminal hole, and a glue hole 4 is provided between the L-line terminal hole and the N-line terminal hole. In this way, the inner frame and the rubber material can be fixed together in an all-round manner from three directions, which greatly improves the tension reliability of the connector. At the same time, the three glue holes 4, 5, 6 are directly opposite to the parting surface of the cover 3, and there is no need to do side core pulling when designing the mold of the cover 3, which not only simplifies the structure of the cover mold but also improves the life of the cover mold.

[0027] like Figure 5 As shown, the end face 18 of the enclosure 17 is inclined, so that when the inner frame is impacted by the high-pressure rubber in the mold, the impact force around it can be converted into a forward squeezing force on the inner frame, such as Figure 8 As shown, the direction of the arrow in the figure is the direction of the extrusion force. The extrusion force makes the sealing step 7 contact with the mold more closely, making the sealing ability of the inner frame more reliable.

[0028] The above embodiments do not limit the present invention in any way, and any technical solutions obtained by equivalent replacement or equivalent transformation fall within the protection scope of the present invention.
