Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to a novel type of ribbon cable connector. Background Technology

[0002] Ribbon cable connectors, as components used to connect circuit boards in electronic devices, are primarily used for transmitting signals and power. They consist of multiple tiny wires arranged in a ribbon shape, fixed to the circuit board by connectors to achieve reliable connections between circuits. Ribbon cable connectors are widely used in computers, communication equipment, and home appliances, favored for their compact structure, reliable connection, and easy installation. Terminal blocks, on the other hand, function by supporting multiple insulated terminal components, enabling wiring connections between devices inside and outside the enclosure. They also make wiring more aesthetically pleasing and maintenance easier, and are widely used in electrical control cabinets, power distribution systems, and other similar applications. The application of ribbon cable connectors and terminal blocks has greatly promoted the development of the electronics and electrical fields, making circuit connections in equipment more efficient and stable.

[0003] In existing technologies, ribbon cable connectors and terminal blocks are commonly used to achieve wiring connections between circuit boards and between circuit boards and devices / assemblies. Ribbon cable connectors come in many types, and can be categorized by interface type as IDC (Insulation Displacement Connector), FPC (Flexible Printed Circuit Connector), and FFC (Flat Flexible Cable Connector). IDC connectors pierce the insulation layer to contact the wires and are suitable for connecting multi-core cables; FPC connectors are used to connect flexible circuit boards and are characterized by their thinness and flexibility; FFC connectors are used to connect flat cables and are suitable for high-density wiring. Terminal blocks, on the other hand, are components used in the electronics and electrical fields to achieve wiring connections. The wires are fixed at both ends by fastening screws, and their form and functional logic match those of "terminal blocks."

[0004] Traditional terminal blocks often adopt a long strip shape, which results in low connection stability of ribbon cable connectors and a high failure rate during equipment use. Utility Model Content

[0005] This application provides a novel type of ribbon cable connector, which uses trapezoidal terminal blocks to form a stepped cable inlet, thereby improving the connection stability of the ribbon cable connector and reducing the equipment failure rate.

[0006] This application provides a novel type of ribbon cable connector, which adopts the following technical solution: A novel ribbon cable connector includes a connector latch, a connector plastic body, and a terminal isolation mechanism located between the connector latch and the connector plastic body. The terminal isolation mechanism includes multiple sets of terminal blocks and terminals. The terminal blocks have a trapezoidal structure, and a stepped inlet is formed between adjacent terminal blocks. The terminals are fixed in the stepped inlet and connected to the connector plastic body.

[0007] By adopting the above technical solution, this utility model designs a novel type of ribbon cable connector. In use, a terminal isolation mechanism is installed between the connector lock and the connector plastic body. The terminal isolation mechanism consists of terminal blocks and terminals. A stepped inlet is formed between the terminal blocks. One end of the terminal is inserted into the stepped inlet, and the other end is inserted into the connector plastic body, thereby connecting and fixing the connector lock and the connector plastic body. This solution changes the terminal block from a strip structure to a trapezoidal structure, making the inlet stepped, thus ensuring a tight and fixed connection between the ribbon cable and the ribbon cable connector.

[0008] Preferably, the terminal has a barb at its end, the stepped inlet is wider at the top and narrower at the bottom, and the barb is embedded in the stepped inlet and forms a clamping fit with the connector plastic body.

[0009] By adopting the above technical solution, the stepped inlet, which is wider at the top and narrower at the bottom, limits the barb at the end of the terminal during use. This, combined with the connector's plastic body, forms a clamping effect, making the connection between the ribbon cable and the ribbon cable connector more stable.

[0010] Preferably, there are two barbs, and the two barbs are symmetrically distributed along the end of the terminal.

[0011] By adopting the above technical solution, the two barbs symmetrically distributed along the ends of the terminals can more securely engage with the stepped inlet during use, further enhancing the connection stability between the ribbon cable and the ribbon cable connector.

[0012] Preferably, the connector plastic body has limit grooves at both ends, and the connector lock has first limit blocks at both ends. The first limit blocks are installed in the limit grooves, and the ends of the first limit blocks have protrusions.

[0013] By adopting the above technical solution, when in use, limiting grooves are set at both ends of the connector plastic body, and first limiting blocks are set at both ends of the connector lock. The first limiting blocks are installed in the limiting grooves, and the ends of the first limiting blocks are provided with protrusions, which can limit the connector lock and the connector plastic body.

[0014] Preferably, the inner wall of the first limiting block is set as an inclined surface, and the two ends of the connector lock are provided with conical protrusions that fit with the inclined surface. The conical protrusions abut against the inclined surface to restrict the movement direction of the connector lock.

[0015] By adopting the above technical solution, when in use, the inclined surface of the inner sidewall of the first limiting block fits against the tapered protrusions at both ends of the connector lock, which can effectively limit the movement direction of the connector lock.

[0016] Preferably, the terminal isolation mechanism extends into a snap-fit ​​structure at both ends, the snap-fit ​​structure including a slot fixed to the connector plastic body, the slot being used to accommodate a first limiting block of the connector lock.

[0017] By adopting the above technical solution, when in use, the terminal isolation mechanism of the new type of ribbon cable connector extends out of both ends with a snap-fit ​​structure with a slot. The slot can accommodate the first limiting block of the connector lock, so that the connector lock and the connector plastic body are fixed together by the snap-fit ​​structure.

[0018] Preferably, the cross-sectional shape of the buckle structure remains consistent along the length direction, and the buckle structure is integrally formed with the terminal isolation mechanism.

[0019] By adopting the above technical solution, the cross-sectional shape of the snap-fit ​​structure remains consistent along the length direction and is integrally formed with the terminal isolation mechanism during use, which makes the manufacturing of the snap-fit ​​structure more convenient and the overall structure more robust.

[0020] Preferably, the buckle structure is provided with two second limiting blocks symmetrically distributed along the buckle groove.

[0021] By adopting the above technical solution, two second limiting blocks symmetrically distributed along the slot are set on the buckle structure during use, which can further limit the terminal isolation mechanism.

[0022] In summary, this application has the following beneficial effects: 1. The present invention discloses a novel type of ribbon cable connector, wherein the terminal blocks are trapezoidal in structure, so that adjacent terminal blocks form a stepped inlet that is wider at the top and narrower at the bottom, which can make the ribbon cable and the ribbon cable connector tightly and fixedly connected. 2. The present invention provides a novel type of ribbon cable connector in which the barb at the end of the terminal forms a clamping engagement with the connector plastic body, making the terminal more secure and preventing it from loosening; 3. The present invention discloses a novel type of ribbon cable connector in which the connector lock and the connector plastic body cooperate through a limiting groove, a first limiting block and other structures to restrict the movement direction of the connector lock, ensure the stability of the connection and reduce the possibility of connection failure due to component movement.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] This utility model discloses a novel type of ribbon cable connector, such as... Figures 1 to 3 As shown, the connector includes a connector lock 1, a connector plastic body 2, and a terminal 32 isolation mechanism 3 located between the two. The connector lock 1 is connected to the connector plastic body 2, and the terminal 32 isolation mechanism 3 is fixed between the connector lock 1 and the connector plastic body 2. This achieves the effect of improving the connection stability of the ribbon cable connector. The reason is that this structure can protect and fix the internal components such as the terminal 32, making the ribbon cable connection more stable.

[0026] Specifically, the terminal 32 isolation mechanism 3 includes multiple sets of terminal blocks 31 and terminals 32. The terminal blocks 31 have a trapezoidal structure, an innovative design that differs from traditional long strip terminal blocks 31. The trapezoidal terminal blocks 31 can be made of metal, such as copper alloy, which has good conductivity and a certain strength. Of course, they can also be made of composite materials with good conductivity. A stepped wire inlet 4 is formed between adjacent terminal blocks 31. The stepped wire inlet 4 is wider at the top and narrower at the bottom. This design facilitates the insertion of the ribbon cable and can better fix the ribbon cable. The formation of the wire inlet is due to the special arrangement of adjacent trapezoidal terminal blocks 31, which makes its space present a state of being wider at the top and narrower at the bottom.

[0027] Terminal 32 is fixed in the inlet and connected to the connector plastic body 2. Terminal 32 is a sheet-like structure and can also function as a connector for ribbon cables. The connection between terminal 32 and connector plastic body 2 can be achieved by embedding part of terminal 32 into connector plastic body 2 through injection molding, or by adhesive bonding, etc.

[0028] Two barbs 5 are provided at the end of terminal 32, and the two barbs 5 are symmetrically distributed along the end of terminal 32. The barbs 5 can be integrally molded from the same material as terminal 32. The function of the barbs 5 is to be embedded in the stepped cable inlet 4 and form a clamping engagement with the connector plastic body 2, further enhancing the connection stability between the ribbon cable and the connector.

[0029] The connector plastic body 2 has limiting grooves 6 at both ends, which can be rectangular or trapezoidal in shape. The connector locking 1 has first limiting blocks 7 at both ends, which are installed within the limiting grooves 6. The ends of the first limiting blocks 7 have protrusions. These protrusions prevent the limiting blocks from dislodging from the limiting grooves 6.

[0030] The inner wall of the limiting block is set as an inclined surface, and both ends of the connector lock 1 are provided with conical protrusions 8 that fit against the inclined surface. The conical protrusions 8 abut against the inclined surface to limit the movement direction of the connector lock 1. This design can make the connector lock 1 more stable during installation and use, and prevent it from shaking randomly.

[0031] The terminal 32 isolation mechanism 3 extends into two end segments with snap-fit ​​structures 9. Each snap-fit ​​structure 9 includes a slot 10 fixed to the connector plastic body 2, which accommodates the first limiting block 7 of the connector locking 1. The cross-sectional shape of the snap-fit ​​structure 9 remains consistent along its length and is integrally molded with the terminal 32 isolation mechanism 3. This integral molding design improves the strength and stability of the structure. The snap-fit ​​structure 9 can be made of plastic and manufactured together with the terminal 32 isolation mechanism 3 using an injection molding process.

[0032] The snap-fit ​​structure 9 is provided with two second limiting blocks 11 symmetrically distributed along the snap-fit ​​groove 10. The second limiting blocks 11 can further restrict the position of the connector lock 1, making its installation more accurate and secure.

[0033] The implementation principle of this embodiment is as follows: This novel ribbon cable connector designs the terminal block 31 as a trapezoidal structure, forming a stepped inlet 4. The barb 5 at the end of the terminal 32, in conjunction with the stepped inlet 4 and the connector plastic body 2, significantly improves the connection stability between the ribbon cable and the connector. Simultaneously, the cooperation between the connector lock 1 and the connector plastic body 2 through structures such as the limiting groove 6, limiting block, protrusion, and conical protrusion 8, as well as the snap-fit ​​structures 9 at both ends of the terminal 32 isolation mechanism 3 and the second limiting block 11, further enhances the overall structural stability of the connector, reducing the failure rate during use. Compared to traditional ribbon cable connectors, this represents a significant improvement and enhancement.

[0034] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
