Technical Field
[0001] The utility model relates to the technical field of connectors, in particular to a stable elastic high FPC connector. Background Art
[0002] Flexible printed circuit board, referred to as FPC, is a printed circuit board made of polyimide or polyester film with high reliability and excellent flexibility. It has the characteristics of high wiring density, light weight, thin thickness and good bending performance. It is favored for its excellent characteristics such as light weight, thin thickness and free bending and folding. FPC connectors are mainly used in LCD displays, scanners, and other electronic devices, as well as computer motherboards, LCD monitors, telecommunications cards, memory and mobile hard disks. As various consumer electronic products have now integrated miniaturization, thinness and high performance, the use of flexible printed circuit boards (FPC) and matching FPC connectors to reduce space, reduce weight and reduce assembly costs has been accepted by many customers.
[0003] The contact stability of FPC connectors is an important indicator for measuring product characteristics. The more pins a product has, the longer the product is. In the injection molding industry, the longer the product is, the more serious its deformation is. Therefore, after the product height and pin number are defined, the product structure can only be optimized to reduce the deformation of the product caused by length. However, due to the material properties of plastic materials, the part of the connector shell that does not contact the contact will always have deformation problems, and the distance between the signal contact and the plastic shell cannot be guaranteed, affecting the normal use of the connector.

[0032] The protection structure includes: a protection shell 5, the protection shell 5 is plugged into the upper surface of one end of the housing 1, and a limit post 6 is fixedly arranged inside the lower end of the protection shell 5, and a limit hook 7 is fixedly arranged on the upper end of the signal contact 3;
[0033] One end of the limit hook 7 penetrates the outer surface of the protective shell 5, and the lower surface of the limit hook 7 fits with the upper surface of the limit column 6, and the lower surface of the limit column 6 fits with the outer surface of one end of the signal contact 3;
[0034] During installation, first insert the signal contact 3 from one end of the shell 1 into the plug-in slot 2 on the surface of the shell 1. At this time, the anti-deformation opening 4 cooperates with the signal contact 3 to reduce the overall deformation of the shell 1, and then the protective shell 5 is inserted obliquely downward into the shell 1, so that the limit column 6 enters between the limit hook 7 and one end of the signal contact 3, thereby completing the limitation of the signal contact 3.
[0035] Embodiment 2: This embodiment is disclosed on the basis of Embodiment 1: anti-detachment structures are provided at both ends of the outer shell 1 and the protective shell 5 to prevent the outer shell 1 and the protective shell 5 from being disconnected and to ensure the stable placement of the outer shell 1;
[0036] The anti-slip structure includes: a pull-down column 8, which is fixedly arranged on the outer surface of the protective shell 5, legs 9 are clamped and installed at both ends of the shell 1, and a balance sheet 10 is fixedly arranged on the lower surface of one end of the legs 9, a guide groove 11 and an anti-slip groove 12 are opened inside the shell 1, a guide column 13 is fixedly arranged at the lower end of the legs 9, and an anti-slip sheet 14 is fixedly arranged at the upper end of the legs 9, and a puncture protrusion 15 is fixedly arranged on the upper surface of the anti-slip sheet 14;
