Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a novel interlocking connector. Background Art

[0002] There is no plastic wall next to the terminal pins of traditional connectors, so the terminal pins are prone to interfere with each other or when welding, too much solder paste overflows or is too close to the adjacent terminal pins, causing two adjacent terminal pins to short-circuit or the solder paste is too close to interfere with each other, causing product damage or malfunction. In addition, the base has no reinforcement ribs to increase stability. After the FPC is installed, a cover is needed to cover and press it, which increases the mold opening and production costs of the cover, and the base also needs to be solid injection molded, which cannot save materials.

[0003] In addition, traditional terminals have no rebound force and are prone to metal fatigue. In addition, the contact between the terminal contact point and the FPC gold finger is prone to poor conduction after repeated plugging and unplugging.

[0004] Traditional grounding plates do not have an integrated design and are easy to fall out or have design defects, which can easily cause uneven levels before and after welding. Utility Model Content

Obviously, the described embodiment is only a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0033] As in the background art, the speed uniformity of the manual solid phase extraction device cannot be guaranteed, and it is more laborious, which is not conducive to the extraction speed.

[0034] In order to solve this technical problem, the utility model provides a novel interlocking connector, which is applied to through-type solid phase extraction.

[0035] Specifically, please refer to Figure 1-Figure 4 The novel interlocking connector specifically comprises: a connector body 1, a terminal 4 is arranged inside the connector body 1, one end of the terminal 4 is arranged in a barb shape, and a buckle frame 5 is arranged at the upper end of the connector body 1;

[0036] FPC2, one end of which is fixedly connected with a reinforcing plate 3, and FPC2 is plug-connected with the connector body 1 through the reinforcing plate 3;

[0037] The connector body 1 is fixedly connected to one end close to the FPC2 with a bracket 7, and there are multiple brackets 7. One end of the terminal 4 that is set to be in a hook shape extends to the gap between two adjacent brackets 7. The FPC2 is provided with an end of a reinforcement plate 3 that is inserted into the position between the bracket 7 and the buckle frame 5. The upper part of the end of the terminal 4 that is set to be in a hook shape is fitted with the bottom of the FPC2, and the buckle frame 5 is buckled and connected with the reinforcement plate 3.

[0038] The novel interlocking connector provided by the utility model adopts a multi-structure matching design, so that when the FPC2 is plugged into the connector body 1, the end of the FPC2 can be lifted by the bracket 7, and the reinforcing plate 3 at the end of the FPC2 can be clamped by the matching of the terminal 4 and the buckle frame 5, so that there is no need for a cover to cover the press fit, thereby saving the mold opening and production costs of the cover, and the end of the terminal 4 is arranged in a barbed shape, so that the terminal 4 has a rebound effect, thereby reducing the phenomenon of metal fatigue, and also avoiding the fact that the contact point of the terminal 4 and the gold finger of the FPC2 are easily connected after multiple plugging and unplugging due to the lack of rebound force of the terminal 4.

[0039] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] Embodiment 1:

[0043] Please refer to Figure 1-Figure 4 , a novel interlocking connector, comprising:

[0044] A connector body 1, wherein a terminal 4 is arranged inside the connector body 1, one end of the terminal 4 is arranged in a barb shape, and a buckle frame 5 is arranged at the upper end of the connector body 1;

[0045] FPC2, one end of which is fixedly connected with a reinforcing plate 3, and FPC2 is plug-connected with the connector body 1 through the reinforcing plate 3;

[0046] Furthermore, the end of the connector body 1 close to the FPC2 is fixedly connected with a bracket 7, the number of brackets 7 is multiple, the end of the terminal 4 is set to be hook-shaped and extends to the gap between two adjacent brackets 7, the end of the FPC2 with the reinforcing plate 3 is inserted between the bracket 7 and the buckle frame 5, the upper part of the end of the terminal 4 set to be hook-shaped fits the bottom of the FPC2, and the buckle frame 5 is buckled and connected with the reinforcing plate 3. In order to guide and limit the FPC2 during the connection process between the FPC2 and the connector body 1, the two sides of the connector body 1 close to the end of the FPC2 are fixedly connected to the limit baffle 13, and the height of the limit baffle 13 is the same as that of the bracket 7.

[0047] Furthermore, the middle part of the lower end of the buckle frame 5 is fixedly connected to the connector body 1, and a buckle head 12 is fixedly connected to one end of the buckle frame 5 close to the reinforcing plate 3, and the buckle frame 5 is buckled and connected to the reinforcing plate 3 through the buckle head 12. In order to increase the overall height of the buckle frame 5 and reduce the phenomenon of accidental breakage of the buckle frame 5, a reinforcing rib 10 is fixed to the upper end of the buckle frame 5, and a reinforcing rib 2 11 is fixed to the lower end of the buckle frame 5 and one end away from the buckle head 12.

[0048] It can be seen that terminal 4 is designed in a special shape from front to back, and the front end adopts a hook-shaped design (hereinafter referred to as the hook). When the front end of FPC2 is inserted, the hook will be squeezed, thereby causing downward deformation. When the reinforcement plate 3 of FPC2 is fully installed, the hook will rebound, and the reinforcement plate 3 will be completely locked and engaged with the buckle head 12 part of the front end of the buckle frame 5. Due to the rebound force of the hook, terminal 4 will be in full contact with FPC2. Due to the rebound force, the conductivity is better, and the occurrence of metal fatigue is also reduced. The number of times FPC2 can be installed and removed is increased, thereby increasing the service life of the connector.

[0049] Since the FPC2 above the connector body 1 is designed in the shape of a seesaw and is made of hard plastic, and is reinforced with ribs in the middle, it is normally completely and tightly buckled with the front end of the FPC2. If you need to take out the FPC2, you only need to press down the rear end of the button with your fingers. Due to the deformation of the plastic, the buckle head 12 will tilt upwards. Since the rear end pressing distance of the design is large, the height of the buckle head 12 after tilting is also greater than the total height of the maximum rebound height of the hook plus the thickness of the reinforcing plate 3, so that the FPC2 can be easily taken out. Therefore, this design does not require a plastic cover to fix the FPC2, saving the mold opening fee and production fee of the plastic cover, greatly reducing costs.

[0050] Furthermore, a partition plate is fixed to the end of the connector body 1 away from the hook-shaped end of the terminal 4, and the partition plate separates the end of the connector body 1 away from the hook-shaped end of the terminal 4 into a plurality of partition cavities 6. The number of the partition cavities 6 is the same as the number of the terminals 4, and the other end of each terminal 4 extends to the inner side of the corresponding partition cavity 6.

[0051] It can be seen that the separation cavity 6 can be used to isolate the terminals 4 to prevent excessive solder paste from overflowing onto or getting too close to adjacent terminals 4 during soldering, causing a short circuit between two adjacent terminals 4 or causing solder paste to interfere with each other, resulting in product damage or malfunction.

[0052] Furthermore, a PCB support plate 9 is provided at the lower end of the limit baffle 13 away from one end of the connector body 1, and the PCB support plate 9 is plugged and connected with the limit baffle 13. A conical plug post is provided at the top of the PCB support plate 9, and a matching slot is provided at the lower end of the limit baffle 13 and at a position corresponding to the conical plug post.

[0053] It can be seen that the lower end of the limit baffle 13 is flush with the lower edge of the terminal 4, so that the entire connector can be stably kept in a horizontal direction before and after being soldered to the PCB board, and the upper end has a conical design, which is integrated and embedded with the base.

[0054] Embodiment 2:

[0055] The novel interlocking connector provided in Example 1 is further optimized, specifically, as follows: Figure 4 As shown, a slot 8 is formed at one end of the bracket 7 away from the connector body 1 , wherein the length of the slot 8 is smaller than the length of the bracket 7 .

[0056] Through the above structural design, by opening the empty slot 8 at the end of the bracket 7, the material required for the production of the device is reduced, thereby reducing the production cost.

[0057] Embodiment 3:

[0058] The novel interlocking connector provided in Example 1 or 2 is further optimized, such as Figure 1-Figure 4 As shown, the connector body 1, the bracket 7, and the buckle frame 5 are integrally arranged.

[0059] Through the above structural design, the overall structure of the device is relatively stable, and the installation is relatively convenient and relatively flat after installation.

[0060] Obviously, the embodiments described above are only some embodiments of the utility model, rather than all embodiments. The preferred embodiments of the utility model are given in the accompanying drawings, but they do not limit the patent scope of the utility model. The utility model can be implemented in many different forms.
