The present disclosure provides a connector, and more particularly, to a female socket 1 in a connector. In general, to implement communication connection of a flexible printed circuit board in a terminal device, a connector is used by matching a female socket 1 and a male plug (not shown in the figure), wherein the female socket 1 and the male plug are similar to a power plug, and the two can be electrically connected through simple plugging and unplugging. As shown in fig. 1 and 2, the female socket 1 is configured in a groove shape, i.e. the female socket 1 includes two opposite end walls and two opposite side walls, and for the convenience of description, two opposite short sides in the female socket 1 are referred to as end walls and two opposite long sides are referred to as side walls.

The interior of the female housing 1 is provided with a central island 5, the central island 5 projects upwards from the bottom of the inside of the female housing 1 to a height approximately flush with the top surfaces of the end portions and the side walls, and an annular receiving space for receiving at least a partial area of a male connector is formed between the central island 5 and the end walls and the side walls of the female housing 1. The male head is roughly shaped like a Chinese character 'hui', the middle area is sunken inwards to match with the middle island 5, and the peripheral area is used for being inserted into the accommodating space of the female seat 1.

In order to realize the electrical connection, a plurality of electrical connection devices are further arranged in the female socket 1, the electrical connection devices are usually elastic members, a first end of each electrical connection device elastically abuts against a clamping groove preset on the middle island 5, a second end of each electrical connection device elastically abuts against the inner wall surface of the side wall of the female socket 1, conductive contacts 8 used for being electrically connected with the male connector are arranged at the first end and the second end of each electrical connection device, a signal terminal 6 is further formed at the bottom of the second end of each electrical connection device, and the signal terminal 6 extends out of the bottom of the side wall of the female socket 1 and is grounded.

At two relative tip of female seat 1, be provided with metal reinforcement 2 respectively, the metal reinforcement forms the cover form on the whole and detains the tip at female seat 1 with the cover to can avoid effectively causing the damage to the tip of female seat 1 at the in-process of plug male joint, be favorable to prolonging the life of connector. Meanwhile, the reinforcing part made of metal materials has the function of shielding signals inside the female seat 1, and the metal reinforcing part 2 is also used as a signal terminal, so that the current conduction area is further increased, and the stability of signal transmission is ensured.

In order to reduce the interference between the rf signal and the outside, more specifically, in order to prevent the rf signal from overflowing the female housing 1, the shielding body 3 may be disposed on the outer wall surfaces of the two opposite sidewalls of the female housing 1, so as to form a shielding space inside the female housing 1 together with the metal reinforcement 2, wherein the shielding body 3 is used for grounding.

The related art shown in fig. 3 provides a connector having a shield structure, and specifically, the connector includes a metal reinforcing structure 2 'and a shield structure 3', wherein the metal reinforcing structure 2 'and the shield structure 3' are integrally formed. In general, in order to provide a complete protection for the end of the female socket 1, the metal reinforcing structure 2 'is configured with a relatively complex structure, which is more expensive to design and manufacture, and in addition, the requirements for the material properties of the metal reinforcing structure 2' are higher in order to ensure the current conducting effect. However, for the shielding structure 3 ', the purpose of the arrangement is to form a shielding space together with the metal reinforcing structure 2', which in itself has low requirements on the complexity of the structure and the material properties.

Although the integrally formed metal reinforcing structure 2 'and shielding structure 3' as shown in fig. 3 can simplify the mounting process from the mounting point of view, the overall structure is more complicated, which in turn increases the cost of design and manufacture (mold opening). In addition, metal reinforcing structure 2 'and shielding structure 3' integrated into one piece make shielding structure 3 'also the performance is better but the metal material that the cost is also better simultaneously, promptly, the high performance metal material's that need use quantity also correspondingly increases, undoubtedly can increase the manufacturing cost of connector.

Compared to the metal reinforcement 2, which is complex in structure and requires good electrical conductivity, the shield 3 has lower requirements on the complexity of the structure and the properties of the material, for example, it is made of a lower cost steel material. Therefore, the shield body 3 and the metal reinforcing part 2 adopt a split design, the molding difficulty of the metal reinforcing part and the shield body can be effectively reduced from design to manufacturing process, meanwhile, the split design also enables the shield body to be manufactured by using materials with lower cost, the cost of the connector is further reduced, and the product competitiveness is improved.

In contrast to the first embodiment, in the second embodiment, the end of the shield 3 may not be connected to the third reinforcement portion 23 of the metal reinforcement 2, but may be directly grounded by the first connection portion 31 formed by itself. Also, in this embodiment, the shield body 3 may be configured in a strip shape, and the first connection portion 31 is a fillet formed integrally on the shield body 3. Optionally, the shield 3 is integrally formed with the second plastic 7.
