[0025] See also Figures 3 to 6, is a connector device for an FPC board in some embodiments of the utility model, which includes a base 1, a mounting seat 2 provided on the base 1, a fastener 3 provided on the mounting seat 2 and used to connect with the FPC board, an elastic clip 4 provided on the base 1, and a terminal assembly 5 connected to the base 1. Preferably, the base 1, the mounting seat 2, and the elastic clip 4 can be made by injection molding. In other embodiments, the base 1, the mounting seat 2, and the elastic clip 4 can be connected together by glue or bolts. The fastener 3 is specifically a harpoon fastener, and the terminal assembly 5 can realize the function of transmitting current and signals.

[0026] like Figures 3 to 5 As shown, the elastic snap fastener 4 is provided with a snap-fitting portion 41, and the snap-fitting portion 41 is used to snap-fit ​​to an external mechanism so that the connector device for the FPC board can be fixed and locked. The external mechanism can be a component on the FPC board. The elastic snap fastener 4 includes a first supporting portion 42, a pressing portion 43 and a second supporting portion 44 connected in sequence. One end of the first supporting portion 42 is fixedly connected to the base 1, and one end of the second supporting portion 44 is fixedly connected to the base 1. There is a predetermined gap between the pressing portion 43 and the base 1. More specifically, in this embodiment, the mounting seat 2 is located on the side of the base 1, and the elastic snap fastener 4 is located on the side provided with the mounting seat 2. The mounting seat 2 is located in the mounting space between the pressing portion 43 and the side of the base 1. There is a certain gap between the mounting seat 2 and the pressing portion 43 to provide a certain activity space for the pressing portion 43.

[0027] Furthermore, the engaging portion 41 can be located on the first supporting portion 42 or the second supporting portion 44. The specific setting position of the engaging portion 41 can be adjusted according to the connection position of the external mechanism. In this embodiment, the engaging portion 41 is located on the side of the first supporting portion 42 facing away from the substrate 1. The part of the first supporting portion 42 supporting the engaging portion 41 has a certain gap with the side of the substrate 1. When the pressing portion 43 is pressed, the engaging portion 41 moves accordingly, completing the unlocking of the connector device for the FPC board and the external mechanism. After no longer pressing, the elastic snap member 4 returns to the initial state as a whole, and the locking or removal can be completed at this time. The connector device for the FPC board does not change the connector package (i.e., does not change the relative position between the fastener 3 and the terminal), and the cost is almost not increased. At the same time, the strength of the elastic snap member 4 is improved, so that the connector device has a snap unlocking function.

[0028] It can be understood that the connector device for the FPC board can improve the overall strength of the elastic snap-on component 4 and withstand more pull-off force by providing the first support portion 42 and the second support portion 44. The connector device for the FPC board adds an elastic snap-on component 4 to meet the unlocking requirements of the connector without affecting the function or changing the overall packaging of the connector, and will not interfere with the transmission of the signal. The structure is simple, the cost is low, and it is easy to use.

[0029] Furthermore, the number of the elastic snap fasteners 4 is two, and the two elastic snap fasteners 4 are symmetrically arranged about the central axis of the base 1, and the number of the mounting seats 2 is two, and the two mounting seats 2 are symmetrically arranged about the central axis of the base 1, which can enhance the connection firmness between the connector device for the FPC board and the external mechanism. The central axis is the central axis of the height direction of the base 1.

[0030] like Figure 6 As shown, the mounting seat 2 is provided with a receiving groove 21 for installing the fastener 3, and the fastener 3 is provided with a convex portion 31 that is snap-connected to the receiving groove 21. The number of the convex portions 31 is two, and the two convex portions 31 are respectively arranged on two side surfaces of the fastener 3. The maximum distance between the two convex portions 31 is greater than the distance of the receiving groove 21, so that an interference fit is formed between the fastener 3 and the mounting seat 2, thereby fixing the fastener 3 on the mounting seat 2.

[0031] like Figure 5 As shown, a plurality of first terminal grooves 11 arranged side by side and at intervals and a plurality of second terminal grooves 12 arranged side by side and at intervals are provided on the base 1. The first terminal grooves 11 and the second terminal grooves 12 are separately arranged along the height direction of the base 1, and the first terminal grooves 11 are located below the second terminal grooves 12. The terminal assembly 5 includes a plurality of first connection terminals 51 correspondingly plugged into the first terminal grooves 11 and a plurality of second connection terminals 52 correspondingly plugged into the second terminal grooves 12. The first connection terminals 51 and the second connection terminals 52 are arranged alternately and at intervals with each other along the length direction of the base 1. The bottom surface of the pin portion of the first connection terminal 51 is flush with the bottom surface of the pin portion of the second connection terminal 52, and the peripheral side surface 511 of the pin portion of the first connection terminal 51 is flush with the peripheral side surface 521 of the pin portion of the second connection terminal 52. Among them, the height of the pin portion of the first connection terminal 51 is less than the height of the pin portion of the second connection terminal 52.

[0032] It can be understood that the connector device for the FPC board adopts a new double-row terminal arrangement structure. The connecting terminals have two rows, but there is only one row of soldered pin ends, and the pins of the upper and lower rows of terminals can be flush, and no front-to-back misalignment in the width direction of the substrate 1 will be formed, thus saving the space dimension in the width direction of the substrate 1. More terminals can be arranged in a limited space, which can meet the complex and diverse needs of current products.

[0033] The connector device for the FPC board also includes a fixing body 6 for fixing the terminal assembly 5 in the base 1. When the fixing body 6 is fully installed in the base 1, the fixing body 6 covers all the first terminal grooves 11 and the second terminal grooves 12, and the pin portions of the above-mentioned terminals all protrude from the fixing body 6. If UV glue is subsequently poured at the pin portions, it can be avoided that the UV glue has fluidity and flows into the terminal grooves to block the terminal grooves.

[0034] For example Figure 4 As shown, the fixing body 6 is provided with a protrusion 61 , and the base body 1 is provided with a matching groove 13 matched with the protrusion 61 , so that the fixing body 6 can be clamped on the base body 1 .

[0035] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
