Description

Technical Field

[0001] This utility model relates to the field of ribbon cable connector technology, and in particular to a multi-pin front-flip ribbon cable connector. Background Technology

[0002] Flexible flat cable connectors are a type of electrical connector. They are typically fixed to a circuit board during use, with their terminals connected to the circuit board's electrical potential. When connecting a flexible flat cable, the end of the cable is electrically connected to the connector, thus establishing an electrical connection between the cable and the circuit board. In some cases, the length of the pin slot structure is the same as the overall length of the pin plate. Pins on the pin plate are inserted into their corresponding pin slot areas, and then the back cover is snapped on. When there are many pins, the connector deforms significantly after IR (In-Reflection) testing, leading to deformation and reduced overall connector strength, thus affecting product functionality. Therefore, we propose a multi-pin front-flip cover flexible flat cable connector. Utility Model Content

[0003] To address the aforementioned issues, this invention provides a multi-pin front-flip ribbon cable connector. This invention solves the problem that when the length of some pin slot structures is the same as the overall length of the pin plate, and the areas of the pin plate with pins are all inserted into the corresponding pin slot areas, followed by the back cover being snapped on, the ribbon cable connector experiences significant deformation after IR (In-Reverse) when the number of pins is large. This deformation leads to a decrease in the overall strength of the ribbon cable connector, ultimately affecting product functionality.

[0004] This utility model discloses a multi-pin front-flip cable connector, including a base plate. A PCB circuit board is provided on one side above the base plate. A plurality of equally spaced pin soldering points are provided on the side of the PCB circuit board near the base plate. A terminal block is fixedly soldered on the pin soldering points. A support body is provided on the upper end of the terminal block. A cover plate is provided on the side of the support body away from the terminal block.

[0005] The supporting body includes a plastic bracket, the plastic bracket has a mounting groove in the middle that matches the wiring terminal, and the plastic bracket has a rotating shaft limiting groove on both sides of the mounting groove;

[0006] The cover plate includes a cover body, which has a terminal slot that matches the wiring terminal. Both ends of the cover body near the terminal slot are provided with end cover pivots. The cover body near the end cover pivots is provided with a clearance groove. Both ends of the cover body away from the end cover pivots are provided with arc-shaped protrusions.

[0007] In the above scheme, the wiring terminal is located inside the support body and is fixedly connected to the cable strip.

[0008] In the above scheme, the end cap shaft is engaged inside the shaft limiting groove.

[0009] In the above scheme, the plastic bracket is provided with glue escape grooves on both sides.

[0010] In the above scheme, the plastic bracket is provided with a grounding plate slot inside the rotating shaft limiting groove, and a grounding plate is inserted into the grounding plate slot.

[0011] In the above scheme, the PCB circuit board has grounding plate soldering points that match the grounding plate on both sides.

[0012] In the above scheme, the upper end of the grounding plate is provided with a limiting plate that matches the end cover rotation shaft.

[0013] The advantages and beneficial effects of this utility model are as follows: This utility model provides a multi-pin front-opening ribbon cable connector. The end cover shaft is engaged inside the shaft limiting groove. Through the mutual cooperation between the end cover shaft and the shaft limiting groove, the cover can rotate around the plastic bracket. Arc-shaped protrusions are provided on both sides of the cover, providing a small force during normal opening and closing of the cover. The cover will not automatically spring open when closed, thus effectively ensuring the stability of the cover after closing. A limiting plate is provided on the grounding plate, changing the conventional structure where the end cover shaft is limited by the plastic bracket. Instead, the grounding plate limits the end cover shaft, reducing the reaction force of the end cover shaft on the plastic bracket and realizing the product's pressure-locked conduction function. This type of ribbon cable connector has a simple structure, is easy to open and close, has good stability after closing, and the stress of the product is effectively released after IR (In-Resistance Testing). The reaction force of the cover shaft on the plastic bracket is small, effectively improving the practicality of the ribbon cable connector. Attached Figure Description

[0025] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings and examples. The following examples are only used to more clearly illustrate the technical solution of this utility model and should not be construed as limiting the scope of protection of this utility model.

[0026] like Figure 1-5 As shown, this utility model is a multi-pin front-flip cable connector, including a base plate 1. A PCB circuit board 2 is provided on one side of the base plate 1. The PCB circuit board 2 is provided on the side of the base plate 1 with multiple equidistant pin soldering points 3. A terminal 4 is fixedly soldered on the pin soldering points 3. The terminal 4 is soldered to the pin soldering points 3 by soldering. A support body 5 is provided on the upper end of the terminal 4. A cover plate 6 is provided on the side of the support body 5 away from the terminal 4.

[0027] The supporting body 5 includes a plastic bracket 51, which is attached to the PCB circuit board 2 by adhesive. The plastic bracket 51 has a mounting groove 52 in the middle that matches the terminal 4. The terminal 4 is inserted into the mounting groove 52. The plastic bracket 51 has a rotating shaft limiting groove 54 on both sides of the mounting groove 52.

[0028] The cover plate 6 includes a cover body 61, on which a terminal slot 62 matching the wiring terminal 4 is provided. Both ends of the cover body 61 near the terminal slot 62 are provided with end cover pivots 63. The cover body 61 near the end cover pivots 63 is provided with a clearance groove 64. Both ends of the cover body 61 away from the end cover pivots 63 are provided with arc-shaped protrusions 65. The end cover pivots 63 are engaged inside the pivot limiting groove 54. Through the mutual cooperation between the end cover pivots 63 and the pivot limiting groove 54, the cover plate 6 can rotate around the plastic bracket 51.

[0029] The terminal block 4 is located inside the support body 5 and is fixedly connected to the cable tray 7.

[0030] The end cap shaft 63 is engaged inside the shaft limiting groove 54.

[0031] Both sides of the plastic bracket 51 are provided with glue escape grooves 55. The setting of glue escape grooves 55 effectively increases the glue content between the plastic bracket 51 and the PCB circuit board 2, thereby effectively ensuring the stability of the connection between the plastic bracket 51 and the PCB circuit board 2.

[0032] The plastic bracket 51 is provided with a grounding plate slot 53 inside the rotating shaft limiting groove 54, and a grounding plate 8 is inserted into the grounding plate slot 53.

[0033] The PCB circuit board 2 has grounding plate soldering points 9 on both sides that match the grounding plate 8.

[0034] The upper end of the grounding plate 8 is provided with a limiting plate 10 that matches the end cover rotating shaft 63.

[0035] Specifically, in this utility model, the support body 5 is integrally molded from plastic, thereby effectively improving the overall strength of the support body 5, allowing the stress of the product to be effectively released after IR (In-Resistance Testing) without affecting the product's function. The support body 5 is molded using a center injection method, ensuring that multiple plastic bodies receive consistent pressure at the same time, while also guaranteeing good consistency in products from a single mold with multiple cavities, without significant differences. The end cap pivot 63 is engaged inside the pivot limiting groove 54, and the end cap pivot 63 and the pivot limiting groove 54... The interaction between the parts allows the cover plate 6 to rotate around the plastic bracket 51. The cover 61 has arc-shaped protrusions 65 on both sides, which exert a small force when the product is opened and closed normally. The cover plate 6 will not automatically pop open when closed, thus effectively ensuring the stability of the cover plate 6 after it is closed. The grounding plate 8 is provided with a limiting plate 10, which changes the conventional structure of the end cover shaft 63 being limited by the plastic bracket 51. Instead, the grounding plate 8 limits the end cover shaft 63, reducing the reaction force of the end cover shaft 63 on the plastic bracket 51 and realizing the function of product pressing and conduction.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
