[0025] Reference below Figures 1 to 3 Embodiments of an optoelectronic connector assembly according to the present disclosure are described in detail.

[0026] The present disclosure provides a photoelectric connector assembly, including a needle seat connector and a flange connector.

[0027] The present disclosure provides a needle seat connector, comprising: a needle seat connector body, on which at least one needle seat end ceramic ferrule and a plurality of metal pins are arranged; a snap component 15, which is arranged on the outer surface of the needle seat connector body 1, the first end 151 of the snap component is fixedly connected to the needle seat connector body 1, the second end 152 of the snap component has a gap with the needle seat connector body, and the second end of the snap component is provided with a protrusion 153. The plugging and unplugging force of the connector assembly can be adjusted by adjusting the length of the second end 152 of the snap component, that is, the length of the gap. The longer the length of the second end 152 of the snap component, the smaller the plugging and unplugging force of the connector assembly. Conversely, the shorter the length of the second end 152 of the snap component, the greater the plugging and unplugging force of the connector assembly. The length range of the second end 152 of the snap component can be 1.5mm-4.5mm. When the length of the second end 152 of the snap component is less than 1.5mm, the plugging and unplugging force is too large to make it difficult to plug and unplug. When it is greater than 4.5mm, the plugging and unplugging force is too small and easy to loosen.

[0028] The present disclosure provides a flange connector comprising: a flange connector body, on which at least one flange-end ceramic ferrule 8 and a plurality of electrical sockets 71 are provided, and the inner wall of the housing of the flange connector body is provided with an inwardly recessed groove 4, wherein the groove 4 comprises a first concave surface 45 located at the bottom of the groove and a first inclined surface 44 as a side wall of the groove. The first concave surface 45 may be an arcuate surface or a plane, and the inclination angle of the first inclined surface 44 relative to the inner wall of the flange connector may be 30-60°.

[0029] When the needle seat connector is inserted into or removed from the flange connector, the protrusion 153 slides along the first inclined surface 44 of the groove side wall into or out of the groove 4. The flange connector can be pulled out of the needle seat connector by simply pulling the needle seat connector, without other operations, and the operation is convenient, realizing quick plugging and unplugging.

[0030] In one embodiment, the inner wall of the flange connector housing is provided with a second concave surface 41 and a second inclined surface 42, and the inner surface 43 of the inner wall is between the second inclined surface 42 and the groove 4. The second concave surface is located at the end of the flange connector housing. When the needle seat connector is inserted into the flange connector, the needle seat connector drives the protrusion 153 to slide from the second concave surface 41 to the inner surface 43 of the inner wall along the second inclined surface 42, and then slides from the inner surface 43 of the inner wall into the groove 4 through the first inclined surface 44. The flange connector can be inserted into the needle seat connector only by pushing the needle seat connector, and no other operations are required. The operation is convenient and quick plugging and unplugging can be achieved. The second concave surface 41 can be an arc surface or a plane, and the inclination angle of the second inclined surface 42 relative to the inner wall of the flange connector can be 30-60°.

[0031] In one embodiment, the needle seat connector also includes: a first end, which is formed by hot melt adhesive through low-pressure injection molding, and the first end fills and covers the first end of the needle seat connector body, the tail end of the needle seat ceramic core, and the tail end of the metal pin; a second end, which is formed by thermoplastic polyurethane elastomer through injection molding and covers the first end.

[0032] The first end is formed by low-pressure injection molding of hot melt adhesive, and the first end fills and covers the first end 13 of the needle seat connector body, the needle seat ceramic ferrule tail 22 and the metal pin tail 32. Low-pressure injection molding is a packaging process method that uses a relatively small injection pressure (1.5 to 10 bar) to inject the packaging material into the mold and quickly solidify it to achieve insulation, temperature resistance and other effects. The first end formed by low-pressure injection molding can provide good protection for optical fibers and printed circuit boards. The second end 10 is formed by injection molding of TPU (Thermoplastic polyurethanes) and covers the first end 9. Double-layer injection molding is used to improve the stability and consistency of the optoelectronic connector assembly. The two ends formed by double-layer injection molding can increase the airtightness of the product itself and prevent bacteria from entering the product from the tail end of the cable.

[0033] The needle seat connector body 1 is provided with at least one optical hole 11 for installing the needle seat end ceramic ferrule 2. The optical hole 11 is a stepped hole and passes through the needle seat connector body 1. The first end 13 of the needle seat connector body is an annular hole seat surrounding the optical hole 11. The annular hole seat is provided with a plurality of first electrical holes for installing the metal pins 3. The second end 14 of the needle seat connector body is provided with an annular groove 12 opposite to the annular hole seat. The needle seat connector body includes but is not limited to a cylinder. At least one optical hole 11 can be set in the middle position of the needle seat connector body 1, and a plurality of first electrical holes can be set at the peripheral position of the needle seat connector body 1, or a plurality of first electrical holes can be set around the optical hole 11. Such a setting can reduce the volume of the needle seat connector.

[0034] The needle seat connector also includes a plurality of metal pins 3. Each metal pin passes through the annular hole seat surrounding the optical hole 11 and extends into the annular groove 12. The metal pin head end 31 is located in the annular groove 12, and the metal pin tail end 32 is located near the first end 13 of the needle seat connector body. The number of metal pins 3 can be 2-15 according to demand, and the number of electrical holes is determined according to the number of metal pins 3.

[0035] The flange connector includes a flange connector body 7 and a flange-end ceramic ferrule 8, wherein the flange-end ceramic ferrule 8 passes through the flange connector body 7. The flange connector body 7 includes an annular boss 72 surrounding the flange-end ceramic ferrule 8 and extending beyond the flange-end ceramic ferrule head 81. The flange connector also includes a plurality of electrical jacks 71 disposed on the annular boss 72, which are disposed surrounding the flange-end ceramic ferrule 8.

[0036] The needle seat connector includes a needle seat end ceramic ferrule 2, which is arranged in the optical hole 11 and passes through the needle seat connector body 1, and can be arranged near the center of the needle seat connector body 1. The needle seat end ceramic ferrule tail end 22 located at the first end 13 of the needle seat connector body is connected to an optical cable (not shown in the figure), and the needle seat end ceramic ferrule 2 is a structure of a ceramic tube covering an optical fiber, and is optically connected to the optical cable through the optical fiber. The needle seat end ceramic ferrule head end 21 located at the second end 14 of the needle seat connector body is installed with a ceramic socket 5, and the needle seat end ceramic ferrule head end 21 is inserted into a part of the length of the ceramic socket 5. When the needle seat connector is plugged into the flange connector, the flange end ceramic ferrule head end 81 is plugged into the remaining length of the ceramic socket 5 and docked with the needle seat end ceramic ferrule head end 21. The ceramic socket 5 is a fragile item and is easy to break. Compared with setting the ceramic socket on the flange connector, the fragile and vulnerable parts are placed at the consumable end, which reduces the risk of damage to the device end connector and effectively extends the service life.

[0037] When the flange connector is plugged into the needle seat connector, the ceramic socket 5 and the outer sleeve 6 are inserted into the space between the annular boss 72 and the ceramic ferrule 8 at the flange end, and the ceramic ferrule head end 81 at the flange end is inserted into the ceramic socket 5 to dock with the ceramic ferrule head end 21 at the needle seat end, and the annular boss 72 is inserted into the annular groove 12 of the needle seat connector. The flange connector also includes a spring and a spring stopper sleeved on the ceramic ferrule 8 at the flange end to ensure the close docking of the ceramic ferrule 8 at the flange end and the ceramic ferrule 2 at the needle seat end.

[0038] When the flange connector is plugged into the needle holder connector, the annular groove 12 and the annular boss 72 of the flange connector are plugged into each other, and the corresponding metal pin head 31 located in the annular groove 12 is plugged into the electrical socket 71 of the annular boss 72. Such an arrangement can reduce the volume of the flange connector and the needle holder connector, and accommodate multiple cables and optical cables in a smaller volume.

[0039] When in use, the optical cable connected to the tail end of the ceramic ferrule at the needle seat end can be connected to the optical cable of the sensor or medical device, and the optical cable connected to the tail end of the ceramic ferrule at the flange end can be connected to the optical cable of the demodulation device.

[0040] The present disclosure provides a measurement system, including the above-mentioned optoelectronic connector assembly and a sensor, the sensor is optically connected to the needle seat end ceramic ferrule tail end 22 of the needle seat connector through an optical cable. The measurement system may also include a demodulator, the demodulator is optically connected to the flange end ceramic ferrule tail end 82 of the flange connector through an optical cable.

[0041] In addition, the technical features disclosed above are not limited to the disclosed combinations with other features. Those skilled in the art may also make other combinations between the technical features according to the purpose of disclosure to achieve the purpose of this disclosure.
