Therefore, when used with connectors using PI reinforcement, the contact area is not precise, resulting in poor strength and a lack of electromagnetic shielding. The connectors also lack a latching function, resulting in poor cable locking and a tendency for the cables to become dislodged in high-vibration environments. Summary of the Invention

[0003] The purpose of the present invention is to address the problems existing in the background technology and propose an electronic cable assembly and a connector adapted therefor. By aligning and bonding the electronic cable and the metal plate, when they are plugged into the connector, they can be accurately plugged in and the plugging reliability and electromagnetic shielding effect can be guaranteed.

DETAILED DESCRIPTION

[0030] Example 1

[0031] like Figure 1-Figure 5 As shown, the electronic cable assembly proposed in this embodiment includes an electronic cable 1, a metal plate 3, and an adhesive layer 2 positioned between and connecting the electronic cable 1 and the metal plate 3. Adhesive layer 2 is a thermosetting adhesive layer that securely connects the electronic cable 1 and the metal plate 3 through heat and pressure. Adhesive layer 2 can be conductive or non-conductive. A conductive adhesive layer is used when the metal plate 3 needs to provide electromagnetic shielding in the electronic device; a non-conductive adhesive layer is used when the metal plate 3 does not.

[0032] The electronic cable 1 has a gold finger 101. The front end of the electronic cable 1 is aligned with the front end of the metal plate 3. The left and right end faces of the electronic cable 1 are aligned with the left and right end faces of the metal plate 3. The metal plate 3 has a buckle portion 31 or a hole 32 or a slot, wherein: Figure 2-Figure 4 The metal plate 3 shown has a snap-fit ​​portion 31. Figure 5 The metal plate 3 shown has a latching hole 32 .

[0033] like Figure 4 As shown, a retention space 201 is formed between the rear end of the electronic cable 1 and the rear end of the metal plate 3, and the retention space 201 is located on the rear side of the adhesive layer 2. The purpose of the retention space 201 is to improve the convenience of operation when the electronic cable assembly is inserted into the connector. The user applies force on the rear end of the metal plate 3 on the cable assembly to push the entire electronic cable assembly into the connector for connection. Specifically, the existence of the retention space 201 can separate the rear end of the electronic cable 1 from the rear end of the metal plate 3, and the electronic cable 1 is flexible, so when the user applies force on the rear end of the metal plate 3, the electronic cable 1 below the retention space 201 is pressed down and stretched by the finger, and the finger can fully act on the rear end of the metal plate 3 when applying force. If the coating range of the adhesive layer 2 is relatively large, the upper metal plate 3 and the lower electronic cable 1 will be completely bonded together by the adhesive layer 2. When the electronic cable assembly is inserted into the connector, there is no force point at the tail end, and the operation of inserting the electronic cable assembly into the connector is inconvenient.

[0034] This embodiment achieves basic circuit continuity by aligning and bonding the electronic cable and metal plate. The gold finger 101 provides stronger support at the contact point, thus achieving electromagnetic shielding for the circuit. When plugged into the connector, it can be precisely inserted, ensuring plugging reliability and electromagnetic shielding effectiveness.

[0035] Example 2

[0036] like Figure 1 、 Figure 6-Figure 13 As shown, the connector proposed in this embodiment is suitable for the electronic cable assembly in Example 1. The connector includes a metal shell 6, a plastic part 5 that is snap-connected to the metal shell 6 and forms an insertion space on the inner side, and a plurality of metal terminals 4 that are snap-connected to the plastic part 5. The plastic part 5 has a plurality of sockets 51 for the metal terminals 4 to be inserted into and mounting holes 52 for the metal terminals 4 to pass through. The metal shell 6 has a downwardly protruding bump portion 62. The front of the electronic cable assembly is inserted into the insertion space, and the metal plate 3 is snap-connected to the metal shell 6. The stacked arrangement structure of the connector makes the connector more robust. The gold finger 101 contacts the metal terminal 4, and the bump portion 62 abuts the top of the metal plate 3. The bump portion 62 not only has the function of connecting the metal shell 6 to the ground terminal of the electronic cable assembly for electrical signal connection, but also has the function of pressing the electronic cable assembly, so that the gold finger 101 on the electronic cable 1 can contact the metal terminal 4 on the connector more firmly.

[0037] like Figure 6 and Figure 7As shown, the metal shell 6 is a U-shaped structure with retaining holes 603 on both sides and a baffle 63 at the front to position the electronic cable assembly during insertion. Each lateral end of the metal shell 6 has solder tabs 61, which are used to solder the connector to the PCB during client use. Each end of the plastic component 5 has a retaining plate 501 that inserts into the retaining holes 603. The retaining plate 501 has an inclined surface that guides the plastic component 5 during insertion into the metal shell 6. When inserted into place, the retaining plate 501 of the plastic component 5 rebounds and locks into the retaining hole 603.

[0038] like Figures 8-10 As shown, the metal terminal 4 includes a main body 41, a socket portion 42 integrally connected to the main body 41, and a guide portion 43 integrally connected to one end of the main body 41. The main body 41 and the socket portion 42 are roughly in an inverted T shape, and the guide portion 43 is located above the main body 41. The socket portion 42 is inserted into the socket 51, and the socket portion 42 has a barb portion 421 that is clamped in the socket 51, so that the metal terminal 4 can be firmly connected to the plastic part 5. The guide portion 43 is an inverted V-shaped structure and the upper part protrudes from the top of the mounting hole 52. The guide portion 43 of the inverted V-shaped structure can guide the process of plugging the electronic cable assembly from either direction on both sides, without distinguishing the front and back of the two rows of metal terminals 4. That is, no matter how the electronic cable assembly is plugged in, the gold fingers 101 of the electronic cable 1 can be electrically contacted with the two rows of metal terminals 4.

[0039] The plastic component 5 has a stop 53 located above the mounting hole 52. The outer end of the guide portion 43 is integrally connected to a stop 44 that blocks the underside of the stop 53. To address the problem in existing connectors where the metal terminals lack head protection, the terminals are susceptible to upward force when the cable is inserted horizontally, causing deformation and poor contact. The stop 53 in this embodiment blocks and limits the stop 44, preventing it from tilting up and avoiding deformation of the metal terminal 4 that could lead to poor contact.

[0040] The metal shell 6 has a second latch hole 601 or a second latch slot or a second latch portion 602, with three structural styles. Figure 11 The metal shell 6 shown has a second latch hole 601. Figure 12 and Figure 13The metal shell 6 shown has a second snap-on portion 602. The connection between the electronic cable assembly and the connector is enhanced by a snap-on arrangement between the metal plate 3 and the metal shell 6. When the metal plate 3 has a first snap-on portion 31, the metal shell 6 has a second snap-on hole 601 or a second snap-on slot for the first snap-on portion 31 to snap into. When the metal shell 6 has a second snap-on portion 602, the metal plate 3 has a first snap-on hole 32 or a first snap-on slot for the second snap-on portion 602 to snap into. Furthermore, the metal plate 3 and the metal shell 6 can both have snap-on portions, i.e., snap-on portions 1 31 and 2 602 are used for snapping. The snap-on portions have guide slopes to guide the snap-on process. Once snapped into place, they limit each other to prevent them from falling out. If the electronic cable assembly needs to be removed later, the user presses down on the metal plate 3 with their fingers to misalign the first snap-on portion 31 and the second snap-on portion 602, and then pulls outward to remove the electronic cable assembly. The circuit connection between the electronic cable assembly and the connector is highly reliable and easy to disassemble and repair. In high-vibration environments, the electronic cable is not likely to loosen from the connector.

[0041] like Figure 1 As shown, metal plate 3 has outward-projecting convex plates on both sides of its rear end, each with a U-shaped groove or a U-shaped access opening 301 formed between the plate and the connector. When the front end of the cable assembly abuts against baffle 63, the cable assembly and connector are properly connected, and the gold fingers 101 effectively contact the metal terminals 4. When the cable assembly needs to be removed, the U-shaped groove or access opening 301 allows for easy access by the user, ensuring sufficient space for operation. The cable assembly can be removed by pressing down and pulling outward on metal plate 3.

[0042] In this embodiment, the front of the electronic cable assembly is inserted into the insertion space inside the connector, and the front end abuts against the baffle portion 63 for positioning during the plug-in process. The protrusion portion 62 abuts against the metal plate 3 and the snap connection between the metal plate 3 and the metal shell 6 is used to improve the connection reliability. The electronic cable assembly will not have the problem of swinging left and right, the connection is stable, and the gold finger 101 of the electronic cable 1 can maintain contact with the metal terminal 4.

[0043] When the adhesive layer 2 is a conductive adhesive layer, the connection position of the electronic cable 1 is connected to the upper metal plate 3 through the middle adhesive layer 2. The metal plate 3 is then connected to the bump portion 62 on the connector metal shell 6, thereby shielding external electromagnetic interference signals.

[0044] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
