Referring to fig. 1 and fig. 2, the present embodiment provides a connector, which includes a pin header 10 and a fixing base 20 for fixing the pin header 10, wherein the pin header 10 is clamped in the fixing base 20.

The PIN header 10 comprises a rubber shell 11 and PIN PINs 12 clamped in the rubber shell 11 in an array manner; the PIN 12 comprises a welding part 121 and a plug part 122 which are vertically connected with each other; the soldering portion 121 is configured to be inserted into the external PCB100, and the insertion portion 122 is configured to be inserted into the female socket.

The fixing base 20 includes a fixing portion 21 and an engaging portion 22, and the fixing portion 21 and the engaging portion 22 are integrally formed. The fixing portion 21 is used to fix the fixing base 20 to an external PCB. The fixing portion 21 is provided with a stop surface 211 and a positioning post 212 protruding from the stop surface 211. In actual use, the positioning column 212 is inserted into a positioning hole pre-opened on the PCB, and the stop surface 211 directly contacts with the PCB.

The engaging portion 22 is provided with a plurality of locking projections 221, the fixing base 20 is inserted on the PCB, the end surfaces of the locking projections 221 directly contact with the PCB, and form a supporting plane together with the stop surface 211. Specifically, in order to make the fixing base 20 more stable when inserted on the PCB, the plurality of clamping bosses 221 are arranged in a row in an array; the clamping bosses 221 arranged in an array are arranged at one end of the clamping part 22 far away from the fixing part 21, so that the situation that the fixing base 20 tilts up or falls down due to the pressing end part can be effectively avoided.

Referring to fig. 3 and 4, the pin 12 is clamped between the clamping bosses 221, so that the pin header 10 is fixed to the fixing base 20, the soldering portion 121 is parallel to the positioning post 212, and an end portion of the soldering portion 121 protrudes out of the stop surface 211, passes through a through hole preset on the PCB, and is soldered to the back surface of the PCB; the end of the plug-in part 122 is suspended outside the fixing base 20. The pin header 10 is clamped on the fixed seat 20, and the end surface of the rubber shell 11 is lower than or parallel to the end surfaces of the stop surface 211 and the clamping boss 221, so that the end surfaces of the stop surface 211 and the clamping boss 221 are directly contacted with the front surface of the PCB.

Note that, in order to sufficiently clamp the PIN 12, the width of the PIN 12 is larger than the width of the gap between two adjacent detent projections 221. Meanwhile, in order to ensure that when the PIN 12 is clamped between the clamping bosses 221, the clamping bosses 221 are extruded from the PIN 12 to have a certain deformation space, and the PIN 12 is inserted into the gap between the clamping bosses 221 at intervals, namely, only one PIN 12 is clamped between every two clamping bosses 221.

In this embodiment, in order to fix the PIN header 10 on the fixing base 20 more firmly, a row of clamping bosses 221 are added to the clamping portion 22 for clamping the PIN 12, and each PIN 12 that is clamped between the clamping bosses 221 has two positions clamped between the clamping bosses of the array, so as to increase the clamping force of the clamping bosses 221 on the PIN header 10.
