Description

Technical Field

[0001] This utility model relates to the field of connector technology, and specifically to a connector with a secure connection. Background Technology

[0002] In electronic devices, FPCs (flexible printed circuit boards) are widely used due to their flexibility and high wiring density. Their stable connection with connectors directly affects device performance. Existing FPC connectors typically only use a single-time locking mechanism with a pressure cap at the rear of the connector base. This pressure cap is fixed by rotating and pressing the FPC together. However, in scenarios involving long-term vibration, frequent insertion and removal, or changes in ambient temperature (such as automotive electronics and industrial control equipment), this single locking structure is prone to loosening due to slight deformation or vibration of the FPC, leading to signal transmission interruptions and poor contact. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a connector with a firm connection.

[0004] The objective of this utility model can be achieved through the following technical solution: A securely connected connector includes a rubber base, terminals, and a locking cap. The rubber base has a slot, and the slot has spaced-apart limiting grooves for installing terminals. The front end of the rubber base has a fixing seat, and guide rods are symmetrically arranged on both sides of the fixing seat. Guide holes are provided on the rubber base corresponding to the positions of the guide rods. The fixing seat has a buckle, and the rubber base has a buckle groove corresponding to the position of the buckle. The fixing seat has a clearance groove corresponding to the slot. Sliding grooves are provided on both sides of the clearance groove, and pressure plates are slidably arranged in the sliding grooves. The pressure plates are locked to the fixing seat by screws.

[0005] Preferably, the bottom of the clearance groove is provided with a rubber pad opposite to the bottom of the pressure plate.

[0006] Preferably, the rubber pad has anti-slip grooves.

[0007] Preferably, the terminal includes an upper clamping arm and a lower clamping arm, the middle parts of the upper clamping arm and the lower clamping arm are connected as one piece by a support arm, the front end of the upper clamping arm is provided with a contact point, and the end of the lower clamping arm is provided with a welding foot.

[0008] Preferably, the pressure cap includes a support portion, both ends of which are rotatably connected to the rubber seat. One side of the support portion is provided with a pushing portion, and the other side is provided with a pressing portion.

[0009] Preferably, the two ends of the adhesive base are provided with grooves, and the grooves are provided with shielding sheets.

[0010] The beneficial effects of this utility model are: by setting a fixed seat and a pressure plate to form a secondary fixing structure, on the basis of the initial locking of the FPC by the pressure cover, the FPC is locked by screws using the pressure plate, forming a double locking mechanism, which can effectively prevent the influence of external forces such as vibration and deformation on the FPC, avoid the FPC from shifting or loosening in the slot, ensure that the terminal and the FPC are always in stable contact, and reduce the risk of signal transmission interruption and poor contact.

[0018] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0019] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See Figures 1 to 5 As shown, the structure of this utility model is as follows: a firmly connected connector, including a rubber base 1, terminals 2, and a locking cover 3. The rubber base 1 has a slot 4, and the slot 4 has spaced-apart limiting grooves 5 for installing terminals 2. The front end of the rubber base 1 has a fixing seat 6, and the fixing seat 6 has guide rods 7 symmetrically arranged on both sides. The rubber base 1 has guide holes 8 corresponding to the positions of the guide rods 7. The fixing seat 6 has a buckle 9, and the rubber base 1 has a buckle groove 10 corresponding to the position of the buckle 9. The fixing seat 6 has a relief groove 11 corresponding to the slot 4. The relief groove 11 has sliding grooves 12 on both sides. The sliding groove 12 has a pressure plate 13 slidably arranged in the sliding groove 12. The pressure plate 13 is locked to the fixing seat 6 by screws. Specifically, the rubber base 1 is the main frame of the connector, the middle slot 4 is for FPC insertion, the limiting grooves 5 in the slot 4 are used to fix the terminals 2 to ensure stable conductive contact, and the locking cover 3 is used to lock the terminals 2 inserted into the slot 4. The front mounting base 6 is installed by aligning the guide rods 7 on both sides with the guide holes 8 of the rubber base 1 to ensure accurate positioning. It is then fixed by snapping the buckle 9 into the slot 10, which also makes the mounting base 6 detachable. The clearance groove 11 on the mounting base 6 is aligned with the slot 4, so as not to affect the passage of the FPC. The sliding grooves 12 on both sides of the clearance groove 11 contain pressure plates 13. When the screws are tightened, the pressure plates 13 press the FPC, forming a secondary fixation, which can effectively prevent the FPC from loosening.

[0022] like Figure 4 As shown, the bottom of the clearance groove 11 is provided with a rubber pad 14 opposite to the bottom of the pressure plate 13. Specifically, the rubber pad 14 can absorb the pressure applied by the pressure plate 13 to prevent the FPC from being damaged due to excessive compression. At the same time, the rubber pad 14 can also increase the coefficient of friction to prevent the FPC from sliding during vibration.

[0023] Furthermore, the rubber pad 14 is provided with anti-slip grooves 12. Specifically, the anti-slip grooves 12 further enhance the friction of the rubber pad 14 by increasing the surface roughness.

[0024] like Figure 5As shown, terminal 2 includes an upper clamping arm 15 and a lower clamping arm 16. The upper clamping arm 15 and the lower clamping arm 16 are connected as one unit in the middle by a support arm 17. The front end of the upper clamping arm 15 is provided with a contact 18, and the end of the lower clamping arm 16 is provided with a soldering foot 19. Specifically, the upper clamping arm 15 and the lower clamping arm 16 are connected as one unit by the support arm 17 in the middle to form an elastic structure similar to an "H". The contact 18 at the front end of the upper clamping arm 15 contacts the solder pad of the FPC, and the elastic deformation of the clamping arm provides a stable contact pressure. The soldering foot 19 at the end of the lower clamping arm 16 is used to solder to the circuit board to realize the circuit connection.

[0025] like Figure 5 As shown, the pressure cap 3 includes a support part 20, which is rotatably connected to the rubber seat 1 at both ends. The support part 20 has a pushing part 21 on one side and a pressing part 22 on the other side. Specifically, the pressure cap 3 is rotatably connected to the rubber seat 1 at both ends through the support part 20. When the pressing part 22 of the pressure cap 3 is pressed, the pushing part 21 rotates upward with the support part 20 as the fulcrum, pushing against the rear end of the upper clamping arm 15 to cause it to move upward and deform. At this time, the upper clamping arm 15 rotates with the middle support arm 17 as the fulcrum, and the front end moves downward under force to achieve clamping and fixing of the inserted FPC.

[0026] like Figure 2 , Figure 3 As shown, the two ends of the adhesive base 1 are provided with grooves 23, and the grooves 23 are provided with shielding sheets 24. Specifically, the shielding sheets 24 are made of metal material. The electromagnetic shielding property of metal is used to reduce the influence of external interference on signal transmission. The grooves 23 ensure that the shielding sheets 24 are tightly attached to the adhesive base 1 to avoid shielding failure due to displacement.

[0027] In practical use, first, align the guide rods 7 on both sides of the fixing base 6 with the corresponding guide holes 8 at the front end of the glue base 1 and insert them so that the buckle 9 on the fixing base 6 is precisely engaged with the slot 10 of the glue base 1. At this time, the clearance groove 11 of the fixing base 6 is aligned with the slot 4 of the glue base 1. Then, insert the FPC through the clearance groove 11 of the fixing base 6 and align it with the slot 4 of the glue base 1 until the FPC is stably in contact with the terminal 2 fixed by the limiting groove 5 in the slot 4. Next, lock the FPC with the pressure cover 3 to prevent the FPC from loosening in the slot 4. Finally, turn the screws on the pressure plate 13 in the sliding groove 12 on both sides of the clearance groove 11 of the fixing base 6. The screws drive the pressure plate 13 to move along the sliding groove 12 towards the FPC until the pressure plate 13 tightly presses the FPC. Through the dual action of the initial fixing of the pressure cover 3 and the secondary locking of the pressure plate 13, the FPC is ensured to always maintain a stable connection.

[0028] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
