Description

Technical Field

[0001] The utility model relates to the technical field of PCB and FPC connection, and more specifically, to a connector for connecting PCB and FPC. Background Art

[0002] In the traditional field of electronic connection technology, the terminal design of the connector has a crucial impact on the overall performance. However, the traditional connector terminal design has significant limitations in many aspects, especially in the design of the contact point;

[0003] The traditional connector terminal design is relatively simple, which is mainly reflected in the number and structure of contact points. Specifically, this design usually only sets one contact point between the upper and lower terminals. Under ideal working conditions, such a design may be able to meet basic connection requirements. However, in actual applications, especially when the connector needs to withstand long-term current transmission, frequent plugging and unplugging operations, or is in a complex environment such as vibration and temperature changes, there are some problems:

[0004] Since there is only one contact point, this point will bear all the current transmission tasks. Long-term high-load work will cause the wear of the contact point material, which will reduce the contact area, increase the resistance, and eventually cause poor contact. Poor contact will not only lead to a decrease in signal transmission quality, but also may cause heat accumulation in the circuit, further aggravating the aging and wear of the contact point; secondly, frequent plugging and unplugging operations will also cause impact and wear on the contact point. Over time, the contact point may lose its stable connection state due to looseness, resulting in poor conductivity of the connector. Especially in a vibration environment, loose contact points are more likely to break or dislocate, further aggravating the problem of poor contact. Therefore, we have made improvements to this and proposed a connector for connecting PCB and FPC. Utility Model Content

The appearance of this phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] As described in the background technology, since there is only one contact point, this point will bear all the current transmission tasks. Long-term high-load work will cause the wear of the contact point material, which will reduce the contact area, increase the resistance, and eventually cause poor contact. Poor contact will not only lead to a decrease in the transmission quality of the signal, but also may cause heat accumulation in the circuit, further aggravating the aging and wear of the contact point; secondly, frequent plugging and unplugging operations will also cause impact and wear on the contact point. Over time, the contact point may lose its stable connection state due to looseness, resulting in poor conductivity of the connector. Especially in a vibrating environment, loose contact points are more likely to break or dislocate, further aggravating the problem of poor contact.

[0034] In order to solve this technical problem, the utility model provides a connector for connecting a PCB and an FPC.

[0035] Specifically, please refer to Figure 1 , Figure 2 , Figure 4-Figure 7 , the connectors for connecting PCB and FPC specifically include:

[0036] The connector upper seat 101 has an air avoidance groove 102 at the bottom, and a plurality of side grooves 103 are provided on both side walls of the air avoidance groove 102. An upper terminal structure 2 is provided between every two side grooves 103. The upper terminal structure 2 includes a terminal body 201 located in the air avoidance groove 102, and clamping arms 203 are fixedly connected to both sides of the terminal body 201, and one end of the two clamping arms 203 is fixedly connected to a contact point body 204, and the clamping arms 203 are inserted into the side grooves 103.

[0037] The connector for connecting PCB and FPC provided by the utility model has an upper terminal structure 2, and the upper terminal structure 2 has two contact point bodies 204, so that the upper terminal structure 2 has two contact points when connected with the lower terminal, so that the contact between the two is closer and the conductivity is better, which greatly enhances the stability and reliability of the connection.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] Embodiment 1 of the utility model of a connector for connecting a PCB and an FPC

[0042] Please refer to Figure 1 , Figure 2 , Figure 4-Figure 7 The utility model PCB and FPC connection connector includes: a connector upper seat 101, both sides of the bottom of the connector upper seat 101 are provided with chamfers, the bottom of the connector upper seat 101 is provided with an air avoidance groove 102, and both side walls of the air avoidance groove 102 are provided with a plurality of side grooves 103, and an upper terminal structure 2 is provided between every two side grooves 103, and the upper terminal structure 2 includes a terminal body 201 located in the air avoidance groove 102, and both sides of the terminal body 201 are fixedly connected with clamping arms 203, and one end of the two clamping arms 203 is fixedly connected with a contact point body 204, and the clamping arms 203 are inserted into the side grooves 103. Through the upper terminal structure 2, the upper terminal structure 2 has two contact point bodies 204, so that the upper terminal structure 2 has two contact points when connected with the lower terminal, so that the contact between the two is closer, the conductivity is better, and the stability and reliability of the connection are greatly enhanced;

[0043] The clamping arm 203 is bent and can generate elastic force when deformed, thereby taking into account the elastic rebound force and reducing metal fatigue. This solves the problem that the elasticity of the touch point and its rebound force are not taken into account in the prior art, which easily causes metal fatigue, and the mechanical fastening of the upper and lower terminals in the prior art does not take into account the metal rebound force, but only has a rigid fastening, which easily causes the deformation of the terminal and the poor conduction caused by metal damage.

[0044] The upper terminal structure 2 is made of phosphor bronze metal alloy, and 1 is made of plastic.

[0045] Further, such as Figure 4-Figure 6 As shown, two welding feet 202 are fixedly connected to the terminal body 201 , and the ends of the two welding feet 202 away from the terminal body 201 are respectively passed through the two sides of the top of the connector upper seat 101 .

[0046] Further, such as Figure 1 As shown, an FPC body 6 is disposed on the top of the connector upper seat 101 , and the FPC body 6 and the connector upper seat 101 are welded together.

[0047] Further, such as Figure 1 As shown, a reinforcing plate body 5 is fixedly connected to the side of the FPC body 6 away from 1, and the outer shape of the reinforcing plate body 5 covers the connector upper seat 101. This arrangement allows the reinforcing plate body 5 to protect the connector upper seat 101, and the support of the welding part of the FPC body 6 by the reinforcing plate body 5 is also conducive to a smoother connector upper seat 101 when welded to the FPC body 6, and can also protect the FPC body 6 in the welding area from being broken, thereby solving the problem that the length of the traditional reinforcing plate does not completely cover the connector terminal pins, making the terminal pins or the FPC circuit soft board easily damaged when under pressure, causing functional defects.

[0048] Embodiment 2 of the utility model connector for connecting PCB and FPC

[0049] The utility model PCB and FPC connection connector is further provided as follows: Figure 1-Figure 3 As shown, a PCB board body 4 is arranged below the FPC board body 6 , and a plurality of lower terminal bodies 302 are fixedly connected to the top of the PCB board body 4 , and the lower terminal bodies 302 are clamped between two contact point bodies 204 .

[0050] Further, such as Figure 3 As shown, the top of the PCB body 4 is fixedly connected with two limit plates 301 located on both sides of the lower terminal body 302, and the two limit plates 301 are fixedly connected with a clamping plate 303 on the sides away from each other. The limit plates 301 can act as the connector lower seat, so that a connector lower seat is saved, the cost of the connector is saved, and a welding process is saved;

[0051] The lower terminal body 302 is made of phosphor bronze metal alloy, and the limiting plate 301 and the clamping plate 303 are also made of plastic.

[0052] Further, such as Figure 1-Figure 2As shown, the bottom end of the connector upper seat 101 is inserted between the two limit plates 301, and connecting plates 104 are fixedly connected to both sides of the connector upper seat 101. A buckle 105 is fixedly connected to the side of the connecting plate 104 away from the connector upper seat 101, and the two buckles 105 are respectively engaged with the bottom of the two clamping plates 303. The engagement of the buckle 105 with the clamping plate 303 can realize the limitation of the connection between the connector upper seat 101 and the limit plate 301, so that the connector can withstand more severe vibrations without falling off, and a slope is set at the bottom of the buckle 105 to facilitate the buckle 105 to pass through the clamping plate 303.

[0053] Furthermore, by pressing the top of the buckle 105 , the bottom of the buckle 105 can be separated from the card plate 303 according to the lever principle, making it easy and convenient to take.

[0054] Further, such as Figure 1 As shown, a plurality of baffles 106 are fixedly connected to both sides of the connector upper seat 101 , and the baffles 106 are in contact with the limiting plate 301 and the top of the clamping plate 303 .

[0055] Embodiment 3 of the connector for connecting PCB and FPC of the utility model

[0056] The utility model PCB and FPC connection connector is further provided as follows: Figure 1 and Figure 3 As shown, two grounding plate bodies 304 are provided at both ends of the two limiting plates 301, and the two grounding plate bodies 304 are welded on the PCB board body 4. Two grooves 107 are provided on the front and back of the connector upper seat 101, and the grounding plate bodies 304 are plugged into the grooves 107. The conventional design uses two grounding plates, while the present application uses four grounding plate bodies 304. The four grounding plate bodies 304 cooperate with the grooves 107 to limit the connector upper seat 101. After the grounding plate bodies 304 are welded to the PCB board body 4, the overall structure is more stable and not easy to be shaken.

[0057] Further, such as Figure 1 and Figure 3 As shown, a spike end 305 is fixedly connected to the side of the grounding plate body 304 , and the spike end 305 contacts the side wall of the groove 107 . The contact between the spike end 305 and the groove 107 can improve the limiting effect on the connector upper seat 101 .

[0058] The grounding plate body 304 and the spike end 305 cooperate to not only limit the electrical function, but also ensure that the connection between the connector upper seat 101 and the limiting plate 301 is more secure;

[0059] The design of the grounding plate body 304 helps to conduct static electricity or other charges in the device to the ground, preventing device damage or electric shock risks caused by charge accumulation, thereby ensuring safe use;

[0060] Terminals are usually used to connect wires to devices or corresponding circuit boards to achieve electrical signal and power transmission between devices. This connection ensures that current or signals can be transmitted from one component to another, allowing the entire system to work properly. Terminals not only provide electrical connections, but also ensure that wires remain firmly fixed in the connector, which helps reduce the risk of loose wires, thereby improving the performance and reliability of the equipment. In addition, terminals can provide mechanical support for wires to prevent them from being damaged or affected by environmental factors. Terminals make the assembly process of electronic products easier and also improve the efficiency of mass production.

[0061] Connector terminals give engineers greater flexibility when designing and integrating new products, as well as when using components to compose systems. This flexibility helps meet a variety of complex design requirements and improve the overall performance of the product.

[0062] When in use, the connector upper seat 101 is inserted between the two limit plates 301. During the insertion process, the contact point body 204 contacts the lower terminal body 302, and the clamping arm 203 is squeezed by the lower terminal body 302 to generate a force so that the contact point body 204 and the lower terminal body 302 are clamped together, and the buckle 105 is first squeezed and expanded by the clamping plate 303, and then buckled at the bottom of the clamping plate 303, that is, the connection is completed. When separating, press the top of the buckle 105, and according to the lever principle, the bottom end of the buckle 105 can be separated from the clamping plate 303, and the connector upper seat 101 is pulled upward to separate the connector upper seat 101 from the limit plate 301.

[0063] 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. On the contrary, the purpose of providing these embodiments is to make the understanding of the disclosure of the utility model more thorough and comprehensive.
