Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electronic equipment, in particular to a vehicle-mounted FFC connector. BACKGROUND

[0002] The vehicle-mounted FFC connector, i.e. flexible flat cable connector, is a new type of data cable produced by high-tech automatic production line through the compression of PET insulating material and extremely thin tinned flat copper wire. In the wide application of electronic equipment, the vehicle-mounted FFC connector as a key component for realizing electrical signal transmission directly affects the overall operation effect of the equipment. At present, the FFC connectors on the market have certain defects in many aspects.

[0003] In terms of electrical signal transmission, the contact mechanism of the current FFC connector is often only the relative contact between copper sheets, and then the electrical signal is conducted. However, the contact pressure between the contact copper sheet and the conducting mechanism is easily affected by factors such as deformation, wear or temperature change after long-term stress or plugging, resulting in a decrease in signal transmission stability. Moreover, the simple relative contact will also appear poor contact due to the deformation of the copper sheet, affecting the efficient transmission of electrical signals. In addition, the single-sided contact cannot ensure that the contact pressure is always in the best range when the deformation of the contact surface caused by external factors (such as vibration, temperature change, long-term use, etc.) cannot be effectively compensated, thereby affecting the stability of the connection and unable to continuously and stably transmit electrical signals.

DETAILED DESCRIPTION

[0033] ​​The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of the present application.

[0034] Referring to Figures 1 to 9 The embodiment of the present application provides a connector, which is mainly applied to the scene of connection between flexible flat cables. In the embodiment, the structure of the connector is improved, so that the connector has the advantage of stable transmission. Specifically, taking the connection between flexible flat cables as an example, as a preferred scheme in the embodiment, the connector is a vehicle-mounted FFC connector, which can ensure the conduction stability when the flexible flat cables are connected.

[0035] Referring to Figures 1 to 9 The present application provides a technical solution: a vehicle-mounted FFC connector, which is mainly applied to the scene of connection between flexible flat cables.

[0036] The connector comprises a conduction mechanism 9 and two positioning plates 1, wherein:

[0037] An installation cavity is formed between the two positioning plates 1, and the opposite surfaces of the two positioning plates 1 are both provided with a contact mechanism 5;

[0038] The contact mechanism 5 comprises a positioning seat 501, which is arranged on the positioning plate 1 and located in the installation cavity. One end of the positioning seat 501 is fixedly connected with a contact copper sheet 502, the contact copper sheet 502 extends along a first direction, the other end of the contact copper sheet 502 is fixedly connected with an elastic sheet 503, and the elastic sheet 503 is arranged obliquely to the contact copper sheet 502. One end of the elastic sheet 503, which is away from the contact copper sheet 502, abuts against the positioning plate 1.

[0039] The conduction mechanism 9 is detachably connected with the installation cavity, and is used for extending into the installation cavity and electrically connected with the contact copper sheet 502 to perform electrical transmission.

[0040] Through the cooperation of the positioning seat 501 and the contact copper sheet 502, an inclined angle is formed between the contact copper sheet 502 and the positioning seat 501, that is, the contact copper sheet 502 is inclined away from the positioning plate 1 and forms a certain angle with the positioning seat 501, so that when the conducting mechanism 9 enters the installation cavity, the contact copper sheet 502 is extruded to deform relatively, thereby tightly fitting the surface of the conducting mechanism 9 to ensure stable transmission of the electrical signal. The spring sheet 503 is pushed outward at the end of the contact copper sheet 502, so that even if the contact copper sheet 502 deforms after long-term use, the elastic force of the spring sheet 503 can still push the end thereof, so that the contact copper sheet 502 continuously fits tightly against the conducting mechanism 9 to ensure the continuity of electrical transmission. During use, the contact copper sheet 502 and the spring sheet 503 are always in a compressed state, and the continuous elastic force can continuously push the contact copper sheet 502 to fit tightly against the conducting mechanism 9 through the elasticity of the spring sheet 503 when the vehicle vibrates, thereby maintaining the stability of the connection. The contact copper sheet 502 and the positioning seat 501 form an inclined angle, and the spring sheet 503 and the contact copper sheet 502 are also arranged in an inclined manner, which can avoid damage caused by the vertical arrangement of the spring sheet 503. In addition, the elasticity of the spring sheet 503 can compensate for the slight deformation of the contact copper sheet 502 caused by thermal expansion and contraction, so as to ensure that the contact pressure always remains within the optimal range. In cooperation with the contact copper sheet 502 and the conducting mechanism 9, even if the pressure of a single contact point 505 changes due to temperature changes, other contact points 505 can still maintain stable connection to ensure the continuity of electrical signal transmission. At the same time, the contact mechanism 5 is arranged on both positioning plates 1, and the same conducting copper sheet 903 is simultaneously subjected to electrical signal transmission through the two corresponding contact mechanisms 5, thereby realizing double-channel signal transmission and further improving the redundancy and stability of signal transmission. The connector has better adaptability to complex working conditions in a vehicle environment and also significantly improves the durability and reliability of the connector, thereby ensuring high performance under vibration, temperature changes, and long-term use.

[0041] The inclined spring sheet 503 can provide a larger elastic deformation space when the connector is inserted, thereby ensuring that the contact between the contact copper sheet 502 and the conducting mechanism 9 is more tight and stable, and effectively reducing the problem of poor contact caused by vibration or external impact. The inclined spring sheet 503 can uniformly distribute stress during installation, thereby reducing the wear of a single contact point 505 and prolonging the service life of the positioning plate 1 and the spring sheet 503. In addition, the metal fatigue of the spring sheet 503 can be reduced. The inclined spring sheet 503 is easier to position and fix during assembly, thereby reducing the complexity and error rate of assembly, simplifying the production process, improving production efficiency, and reducing manufacturing costs.

[0042] In this embodiment, the end of the positioning seat 501 is fixedly connected with the end of the contact copper sheet 502, thereby providing a mounting and fixing basis for the contact copper sheet 502, the elastic sheet 503 and the contact point 505, and forming an inclined angle with the contact copper sheet 502, so that the contact copper sheet 502 has a specific deformation mode when the conductive copper sheet 903 is inserted, thereby ensuring the accurate mounting position of the contact copper sheet 502, the elastic sheet 503 and the contact point 505, ensuring the cooperative work of the components of the contact mechanism 5, realizing stable electrical signal transmission, the contact copper sheet 502 is responsible for conducting electrical signals, and under the interaction of the positioning seat 501 and the conductive copper sheet 903, the contact copper sheet 502 is deformed to fit the surface of the conductive copper sheet 903, thereby realizing the transmission of electrical signals. As a key carrier for electrical signal transmission, the contact copper sheet 502 is tightly fitted with the conductive copper sheet 903, thereby ensuring efficient and stable transmission of electrical signals. The elastic sheet 503 is fixedly connected to the bottom of the contact copper sheet 502 away from one end of the positioning seat 501, thereby providing an outward elastic force for the contact copper sheet 502. After the contact copper sheet 502 is deformed, the end of the contact copper sheet 502 can still be lifted up, so that the contact copper sheet 502 can maintain full contact with the conductive copper sheet 903, thereby enhancing the stability of the contact between the contact copper sheet 502 and the conductive copper sheet 903, making up for the poor contact problem of the contact copper sheet 502 caused by deformation due to long-term stress or plugging, and ensuring the reliability of electrical signal transmission. The contact point 505 is fixedly connected to the top of the positioning seat 501. After the two positioning plates 1 are combined, the contact points 505 are in contact with each other. With the aid of the two contact mechanisms 5, electrical signals of one conductive copper sheet 903 are transmitted at the same time, thereby realizing synchronous contact with the contact points 505 from both sides, further improving the stability of electrical signal transmission, and reducing the risk of affecting normal electrical signal transmission due to single-sided contact problems.

[0043] In the above embodiment, as a preferred solution, the two sides of one end of the positioning plate 1 are fixedly provided with the rotating seat 2, and the two sides of the other end of the positioning plate 1 are fixedly provided with the adjusting seat 3 matched with the rotating seat 2. The inner wall of the adjusting seat 3 is rotatably connected with the outer surface of the rotating seat 2 through a rotating shaft. The positioning plate 1 serves as the basic support structure of the entire connector, thereby providing mounting and fixing positions for other components such as the contact mechanism 5, the mounting mechanism 4, the transmission mechanism 6, the rebound mechanism 7 and the locking mechanism 8. The two positioning plates 1 cooperate with each other to jointly build the main frame of the connector, and under the connection of the rotating seat 2 and the adjusting seat 3, the connector has a certain adjustable flexibility. The rotating seat 2 is installed on the two sides of one end of the positioning plate 1, and cooperates with the adjusting seat 3 to realize the rotatable connection between the two positioning plates 1 through a rotating shaft. After the positioning plate 1 is opened, the locking mechanism 8 can be conveniently installed, and after being closed, the locking mechanism 8 can be fixed;

[0044] More specifically, since the flexible flat cable is connected, the cable can be quickly installed and connected by the relative opening and closing of the two positioning plates 1. When the flexible flat cable is inserted into the installation cavity through the opening, the flexible flat cable is clamped loosely in the installation cavity, which is easy to cause unstable connection. When the connection is tightened, the flexible flat cable is easily bent, which affects the connection and causes trouble for installation. Therefore, by opening and closing the two positioning plates 1, the installation efficiency can be improved, and the stability of the connection can be ensured. The press-type hard splice joint is easy to fall off when used in a vibrating environment. The contact mechanism 5 in the installation cavity can automatically adjust the clamping force according to the thickness of the FFC, ensuring that the connection will not be poor due to loose clamping, and will not cause the flexible flat cable to bend or be damaged due to tight clamping. In a vibrating environment such as a vehicle or industrial equipment, the design of opening and closing can maintain the stability of the connection through the cooperation of the elastic sheet 503 and the contact mechanism 5, reduce the loosening or poor contact caused by vibration, and the structure of the opening and closing is usually simpler than that of the hard splice joint, reducing the number of parts and assembly steps, thereby reducing the manufacturing cost.

[0045] In the above embodiment, as a preferred solution, the installation mechanism 4 is also included, which includes a positioning groove 401, a clamping groove 402 and a positioning hole 403. The positioning groove 401 is opened on the surface of the positioning plate 1 corresponding to the positioning seat 501 to install the positioning seat 501. The clamping groove 402 is opened on one side of the inner bottom wall of the positioning groove 401 to install the elastic sheet 503. The positioning hole 403 is opened on the other side of the inner bottom wall of the positioning groove 401. The positioning groove 401 is opened on the surface of the two positioning plates 1 in contact with each other to accommodate and fix the positioning seat 501, providing an accurate installation position for the positioning seat 501 of the contact mechanism 5, ensuring the accuracy and stability of the installation of the positioning seat 501. The clamping groove 402 is opened on one side of the inner bottom wall of the positioning groove 401 to fix the elastic sheet 503, so that the elastic sheet 503 maintains the correct position in the contact mechanism 5, providing support for the elastic sheet 503 to exert the elastic force on the contact copper sheet 502, ensuring that the elastic sheet 503 can stably provide the elastic force outward to the contact copper sheet 502, even if the contact copper sheet 502 deforms, it can also ensure that it is in full contact with the conductive copper sheet 903, improving the reliability of the electrical signal transmission. The positioning hole 403 is opened on the other side of the inner bottom wall of the positioning groove 401 and is inserted into the outer surface of the lead column 504 to accurately install the lead column 504 and establish a connection between the contact mechanism 5 and the transmission mechanism 6, enhancing the accuracy and stability of the connection between the contact mechanism 5 and the transmission mechanism 6, ensuring that the electrical signal can be smoothly transmitted from the contact mechanism 5 to the transmission mechanism 6.

[0046] Please refer to Figure 11In the embodiment, the inner wall of the clamping groove 402 is fixedly connected with an elastic block 12, the elastic block 12 is arranged corresponding to the elastic sheet 503 and is located between the elastic sheet 503 and the contact copper sheet 502, and the cross section of the elastic block 12 is polygonal;

[0047] The elastic block 12 can be a rubber block or other elastic material arranged in a polygonal shape. The cross section of the elastic block 12 is triangular, and the elastic block 12 is a triangular prism. One surface of the elastic block 12 is fixedly connected with the inner wall of the clamping groove 402, the second surface is abutted with the surface of the contact copper sheet 502, and the last surface is abutted with the surface of the elastic sheet 503. The elastic block 12 arranged in the clamping groove 402 facilitates quick positioning of the position of the elastic sheet 503 when the contact copper sheet 502 and the elastic sheet 503 are installed, avoids shaking of the elastic sheet 503 during use, can provide secondary support for the elastic sheet 503, prolongs the service life of the elastic sheet 503, avoids fatigue fracture or deformation of the elastic sheet 503, and because the elastic sheet 503 is applied to an environment with temperature rise, the hard material of the elastic sheet 503 is matched with the soft material of the elastic block 12 to support the elastic sheet 503 with the elastic block 12, so that the elastic block 12 is not directly used to cause insufficient supporting force of the elastic block 12 under heat. Therefore, the use of the elastic block 12 can improve the efficiency of installation and assembly, avoid fatigue fracture of the elastic sheet 503, and also provide secondary support for the contact copper sheet 502, further improving the stability.

[0048] Please refer to Figure 10 In the embodiment, as a preferred solution, one end of the opposite surfaces of the two positioning plates 1 is fixedly connected with a rubber sheet 11, the rubber sheet 11 is located on one side of the end of the contact copper sheet 502 away from the positioning seat 501, and is used to clamp the conduction mechanism 9 by the two positioning plates 1.

[0049] The rubber sheet 11 is located at one end of the opposite surfaces of the positioning plate 1, which can absorb the vibration and impact generated during vehicle driving, reduce the influence on the contact copper sheet 502 and the transmission mechanism 9, and the high friction coefficient of the rubber sheet 11 can increase the friction between the positioning plate 1 and the transmission mechanism 9, preventing sliding or falling under the action of vibration or external force. Even without direct locking, the rubber sheet 11 can provide sufficient clamping force to ensure the stability of the connection. In combination with the positioning plate 1 turned over, the use of the locking assembly can be reduced. The sealing performance of the rubber sheet 11 can effectively block external pollutants such as dust and moisture from entering the contact area, protecting the contact copper sheet 502 and the transmission mechanism 9, improving the environmental adaptability of the connector, and prolonging its service life. It is especially suitable for complex environments such as vehicle-mounted and industrial equipment. The elastic properties of the rubber sheet 11 can assist the positioning and fixing of the transmission mechanism 9 when the positioning plate 1 is turned over and opened, simplifying the installation process, improving the installation efficiency, reducing the operation difficulty, and being suitable for scenes that need to be frequently plugged in and out. The elastic properties of the rubber block can cooperate with the locking mechanism 8 to realize the rapid connection and secondary locking of the transmission mechanism 9 when the positioning plate 1 is turned over and opened. In the development, testing and upgrading process of vehicle-mounted electronic equipment, the connector needs to be frequently plugged in and out to replace modules or debug functions, which can improve the efficiency and convenience of testing. More specifically, the connector of the vehicle-mounted camera, sensor or control module needs to be plugged in and out multiple times for performance testing or software upgrading. At the same time, the elastic force of the rubber sheet 11 can also cooperate with the rebound mechanism 7 to make the positioning plate 1 relatively turn over, and can also provide flexible connection for the FFC.

[0055] In the present application, the working steps of the device are as follows:

[0056] 1. First, install the lower positioning plate 1 at a suitable position of the circuit board, and then weld and fix the pin 603. The rotating seat 2 is fixedly installed on both sides of the end of one positioning plate 1, the adjusting seat 3 is fixedly installed on both sides of the end of the other positioning plate 1, the adjusting seat 3 is rotatably connected with the rotating seat 2 through a rotating shaft, and the two positioning plates 1 are opened to create operation space for subsequent installation of other components.

[0057] 2. Place the positioning seat 501 in the positioning groove 401 formed in the contacting surface of the positioning plate 1 to ensure accurate installation. Fix the elastic sheet 503 in the clamping groove 402 on one side of the bottom wall of the positioning groove 401 to make the position correct and provide stable elastic force for the contact copper sheet 502. Fix the top of the lead post 504 to the bottom of the positioning seat 501, and then insert the outer surface of the lead post 504 into the positioning hole 403 on the other side of the bottom wall of the positioning groove 401 to complete the installation of the contact mechanism 5 on the positioning plate 1 and establish the connection basis of the contact mechanism 5 and the subsequent transmission mechanism 6.

[0058] 3. Secondly, fix the two ends of the compression spring 702 to the inner side walls of the two limiting holes 701 to complete the installation of the rebound mechanism 7 and provide power assistance for subsequent opening of the positioning plate 1.

[0059] 4. Then, the positioning frame 801 drives the guide block 803 to slide, and the guide block 803 slides in the third stage of the guide groove 804. At this time, the two positioning plates 1 are relatively far away, and the conducting mechanism 9 is placed between the two positioning plates 1 to preliminarily contact the contact mechanism 5. The positioning frame 801 is continuously pushed, and the guide block 803 enters the second stage of the guide groove 804. Because the distance between the guide grooves 804 gradually approaches, the two positioning plates 1 are relatively close, the conducting mechanism 9 gradually penetrates, the contact copper sheet 502 is gradually attached to the conducting copper sheet 903, and until the guide block 803 enters the first stage of the guide groove 804, the two positioning plates 1 are fully clamped, the contact copper sheet 502 fully contacts the conducting copper sheet 903, and the stable transmission of the electrical signal is realized.

[0060] 5. Finally, when the conducting mechanism 9 needs to be pulled out, the locking mechanism 8 drives the conducting mechanism 9 to move outward, and the guide block 803 sequentially passes through the first stage, the second stage and the third stage of the guide groove 804. When the guide block 803 moves to the through groove position of the third stage of the guide groove 804 on the surface of the upper positioning plate 1, the upper positioning plate 1 is bounced upward under the elastic force of the compression spring 702, and the conducting mechanism 9 can be pulled out outward.
