Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to an FPC connector that reduces friction in graphene cables. Background Technology

[0002] FPC connectors are connection interfaces specifically designed for flexible printed circuit boards (FPCs) to enable the transmission of signals and power within electronic devices.

[0003] The prior art (Chinese patent with publication number CN205828802U, publication date 2016-12-21) discloses an FPC connector, including an insulating body, multiple conductive terminals, and a cover. The insulating body has a plug hole and a receiving groove communicating with the plug hole. Each conductive terminal includes a fixed contact portion and a movable contact portion protruding into the plug hole. The cover is located in the receiving groove and is engaged between the movable contact portion and the insulating body. It also includes a shielding shell, which covers the insulating body and has solder feet for soldering to the connector circuit board. Compared with the existing FPC connectors, this FPC connector adds a shielding shell. When the FPC is inserted into the plug hole, the shielding shell covers the FPC and the conductive terminals, which plays a good shielding role and effectively prevents electromagnetic interference.

[0004] While existing connectors can effectively prevent electromagnetic interference, the existing FFC flexible flat cables are constantly being upgraded and modified. Their lower surface has been changed from the original copper foil contact to graphene flat cables. When the flexible flat cable body is plugged in and out, the graphene underneath will be damaged, thus affecting the subsequent use effect.

[0005] Therefore, we propose an FPC connector that reduces friction in graphene cables to address the aforementioned issues. Utility Model Content

[0006] The purpose of this invention is to provide an FPC connector that reduces friction in graphene cables, in order to solve the problem mentioned in the background art that existing FPC flexible cables are constantly being upgraded and modified, with their lower surface changed from the original copper foil contact to graphene cables. When the flexible cable body is being plugged in and out, the graphene underneath will be damaged, thus affecting the subsequent use effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an FPC connector for reducing friction of graphene ribbon cables, wherein a connector cover is rotatably disposed on the connector housing, and a terminal body is mated between the connector housing and the connector cover, and a mating flexible ribbon cable is disposed between the connector housing and the connector cover, characterized in that: a pushing mechanism is disposed inside the connector housing, which can lift the mating flexible ribbon cable, thereby reducing the contact area between the mating flexible ribbon cable and the connector housing.

[0008] Furthermore, a guide portion is provided on the front side of the connector housing, and the guide portion is arranged in an inclined structure towards the outer end of the connector housing, and the length of the guide portion is greater than the maximum value of the straight length inside the connector housing.

[0009] Furthermore, the connector housing has a fixed contact part inside the front side, and the contact part is made of a semi-circular elastic material. The contact parts are arranged in an array and spaced apart from the terminal body.

[0010] Furthermore, the pushing mechanism includes an upper push plate, which is disposed inside the connector housing. After the mating flexible flat cable is assembled, the side of the upper push plate is located below the mating flexible flat cable, and an abutment block is fixedly connected to the upper surface of the other side of the upper push plate.

[0011] Furthermore, the edge of the contact block is arranged in an arc shape, and the contact block is located directly below the shaft end of the connector cover, and the outer side of the shaft end of the connector cover is in contact with the upper surface of the contact block.

[0012] Furthermore, two sets of limiting rods are fixedly connected inside the connector housing, the upper push plate is nested outside the limiting rods, and an auxiliary spring is fixedly connected between the lower surface of the upper push plate and the inner surface of the connector housing.

[0013] Furthermore, the upper push plate forms an elastic structure with the connector housing through an auxiliary spring, and the upper push plate forms a sliding structure through the contact action between the contact block and the shaft end of the connector cover.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The inclined guide section reduces the contact area between the flexible flat cable and the connector housing during assembly. This guides the installation and removal of the flexible flat cable while simultaneously reducing friction between the connector housing and the lower part of the flexible flat cable, preventing damage to the graphene layer underneath due to contact between the flexible flat cable and the plastic housing.

[0016] 2. The contact part set by the flexible structure makes contact with the contact part when the flexible flat cable is inserted and removed, thereby buffering and dispersing the force of insertion and removal of the flexible flat cable, further reducing the shearing during insertion and removal of the flexible flat cable, and preventing graphene from falling off.

[0017] 3. When the upward-protruding contact part comes into contact with the lower surface of the mating flexible flat cable, the contact surface between the mating flexible flat cable and the connector housing can be changed from a single plane to multiple point surfaces, thereby reducing the contact area and further reducing friction to prevent graphene from falling off.

[0018] 4. When it is necessary to plug and unplug the flexible flat cable, the connector cover needs to be flipped up. At this time, the shaft end of the connector cover rotates, and the push plate pops up, causing the flexible flat cable to move slightly upward. The upward movement of the flexible flat cable can reduce the contact between it and the connector shell, thereby reducing the friction between the flexible flat cable and the plastic shell, and further preventing the graphene on the lower surface of the flexible flat cable from falling off.

[0019] 5. When the connector cover is closed, the protruding part on the axial side of the connector cover abuts against the contact part. At this time, the contact part can drive the upper push plate to move downward along the limit rod. With the assistance of the limit rod, the upper push plate can move stably and squeeze the auxiliary spring, causing the auxiliary spring to undergo elastic deformation, so that the upper push plate can move upward under the drive of the subsequent elastic force.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1: As Figure 1 , Figure 2 and Figure 3 The present invention provides the following technical solution: an FPC connector for reducing friction of graphene ribbon cables, comprising a guide portion 4, which reduces the contact area between the flexible ribbon cable 3 and the connector housing 1 during assembly. A connector cover 2 is rotatably mounted on the connector housing 1, and a terminal body 10 is mated between the connector housing 1 and the connector cover 2. A flexible ribbon cable 3 is also provided between the connector housing 1 and the connector cover 2. A guide portion 4 is provided on the front side of the connector housing 1, and the guide portion 4 is inclined towards the outer end of the connector housing 1. The length of the guide portion 4 is greater than the maximum length of the straight section inside the connector housing 1. An abutment portion 5 is fixedly connected inside the front side of the connector housing 1. The abutment portion 5 is made of a semi-circular elastic material and is arranged in an array, spaced apart from the terminal body 10.

[0029] The inclined guide portion 4 reduces the contact area between the flexible flat cable 3 and the connector housing 1 during assembly. This guides the assembly and disassembly of the flexible flat cable 3 while simultaneously reducing friction between the connector housing 1 and the lower part of the flexible flat cable 3, preventing damage to the graphene layer beneath the flexible flat cable 3 due to contact with the plastic housing. The flexible contact portion 5, with its flexible structure, contacts the flexible flat cable 3 during insertion and removal, causing elastic deformation and buffering the insertion and removal forces. This further reduces shearing during insertion and removal, preventing graphene from falling off. When the upwardly protruding contact portion 5 contacts the lower surface of the flexible flat cable 3, the contact surface between the flexible flat cable 3 and the connector housing 1 changes from a single plane to multiple points, reducing the contact area and further reducing friction to prevent graphene from falling off.

[0030] Example 2: Figure 2 , Figure 4 , Figure 5 and Figure 6The technical solution shown herein provides the following technical solution: An FPC connector for reducing friction of graphene ribbon cables, disclosing a pushing mechanism, which can lift the mating flexible ribbon cable 3, thereby reducing the friction between the mating flexible ribbon cable 3 and the plastic soft shell, and further preventing the graphene on the lower surface of the mating flexible ribbon cable 3 from falling off: The push mechanism is provided inside the connector shell 1, which can lift the mating flexible ribbon cable 3, thereby reducing the contact area between the mating flexible ribbon cable 3 and the connector shell 1. The push mechanism includes an upper push plate 9, which is disposed inside the connector shell 1. After the mating flexible ribbon cable 3 is assembled, the side of the upper push plate 9 is located at... Below the flexible flat cable 3, and on the other side of the upper push plate 9, a contact block 6 is fixedly connected. The edge of the contact block 6 is arc-shaped and located directly below the shaft end of the connector cover 2. The outer side of the shaft end of the connector cover 2 contacts the upper surface of the contact block 6. Two sets of limiting rods 7 are fixedly connected inside the connector housing 1. The upper push plate 9 is nested outside the limiting rods 7. An auxiliary spring 8 is fixedly connected between the lower surface of the upper push plate 9 and the inner surface of the connector housing 1. The upper push plate 9 forms an elastic structure with the connector housing 1 through the auxiliary spring 8. The upper push plate 9 forms a sliding structure through the contact action between the contact block 6 and the shaft end of the connector cover 2.

[0031] When it is necessary to plug and unplug the flexible flat cable 3, the connector cover 2 needs to be flipped up. At this time, the shaft end of the connector cover 2 rotates, and the protruding part of its shaft end does not abut against the contact block 6. At this time, the push plate 9 is pushed up under the elastic force of the auxiliary spring 8 and abuts against the flexible flat cable 3, causing the flexible flat cable 3 to move slightly upward. The upward movement of the flexible flat cable 3 can reduce the contact between it and the connector shell 1, thereby reducing the friction between the flexible flat cable 3 and the plastic shell, and further preventing the graphene on the lower surface of the flexible flat cable 3 from falling off. When the connector cover 2 is closed, the protruding part on the side shaft of the connector cover 2 abuts against the contact part 5. At this time, the contact part 5 can drive the push plate 9 to move downward along the limit rod 7. With the assistance of the limit rod 7, the push plate 9 can move stably and squeeze the auxiliary spring 8, causing the auxiliary spring 8 to undergo elastic deformation, so that the push plate 9 can move upward under the subsequent elastic force.
