A long-path gas absorption cell reflective optical system, which includes a first reflector () and a second reflector (), the first reflector () and the second reflector () are set opposite and spaced apart, with the second reflector () having an optical input port () and an optical output port (). The first reflector (), the second reflector (), the optical input port (), and the optical output port () together constitute a multiple reflection optical system; a collimated light beam enters through the optical input port () and reflects between the first reflector () and the second reflector (), finally exiting through the optical output port (). This achieves a longer light path for the collimated light beam within a limited space, allowing for more reflections; the system has a simple structure, relatively simple optical adjustment, is easy to operate, and has stable performance, making it widely applicable in various detection environments.

A high-speed electrical connector, comprising a signal module (). The signal module comprises a contact (). At least one side of the contact is provided with a shield piece (). The signal module further comprises an insulator (). The insulator is formed on the contact and the shield piece by means of injection moulding so as to combine the contact and the shield piece together. The insulator of the signal module of the electrical connector is encapsulated on the contact and the shield piece by means of injection moulding. Thus, the degree of stability of the signal module is enhanced, and the problem that a signal module of an existing high-speed electrical connector is easily deformed is solved.
