[0032] The present invention will be further described below with reference to specific embodiments and accompanying drawings.

[0033] Example 1:

[0034] See Figure 1-10 As shown, this is an optoelectronic connector, which includes a female connector 1.

[0035] The female connector 1 includes: an optical fiber chip module 11, a plastic shell 13, and female connector terminals 14. The optical fiber chip module 11 is fixed on the PCB board 12 and forms an electrical connection. The optical fiber chip module 11 has a light guide part 111 and a matching slot 112. In this embodiment, the female connector 1 is a horizontal female connector. The light guide part 111 is laterally distributed. The insertion direction of the matching slot 112 is parallel or nearly parallel to the PCB board 12. The optical fiber chip module 11 is used for optical signal transmission. The plastic shell 13 has a connector 131 at its front end. The plastic shell 13 has a receiving groove 132 that passes through the connector 131 and extends upward from its lower end. The plastic shell 13 is fixedly mounted on the PCB board 12 and is fitted around the fiber optic chip module 11 through the receiving groove 132 without contact between them. The light guide part 111 is exposed in the connector 131. The female connector terminal 14 is fixed in the plastic shell 13 and the contact part 141 of the female connector terminal 14 is exposed in the connector 131. The female connector terminal 14 is soldered and fixed to the PCB board 12 and is conductive. The female connector terminal 14 is used for electrical signal transmission. In other words, in this utility model, the fiber optic chip module 11 used in the female connector 1 is directly fixed on the PCB board 12, and then the plastic shell 13 with the female connector terminal 14 fixed on it is directly installed on the PCB board 12. The plastic shell 13 does not contact the fiber optic chip module 11, so it will not damage the fiber optic chip module 11 and ensure the quality of the fiber optic chip module 11. The light guide part 111 of the fiber optic chip module 11 is exposed in the connector 131 of the plastic shell 13 and is used to transmit optical signals with the male connector 2 inserted into the connector 131. The plastic shell 13 covers the fiber optic chip module 11, so as to protect the fiber optic chip module 11. The entire female connector 1 has a very simple structure, few parts, and a relatively small overall size, which can be used in scenarios with limited installation space.

[0036] The following describes the assembly structure of the plastic shell 13 and the PCB board 12:

[0037] The lower end of the plastic shell 13 is integrally formed with a plurality of first positioning posts 1320. A plurality of pads 133 are also integrally formed around the lower end surface of the plastic shell 13. Furthermore, the lower end of the plastic shell 13 is integrally formed with a plurality of sets of positioning latches 134, each set of positioning latches 134 including spaced-apart first positioning latches 1341 and second positioning latches 1342. The lower end of the plastic shell 13 is inserted into the first positioning hole 121 of the PCB board 12 through the first positioning posts 1320 for positioning. The lower end surface of the pads 133 abuts against the upper surface of the PCB board 12. To form a support, the first positioning buckle 1341 and the second positioning buckle 1342 are simultaneously inserted into the positioning lock hole 122 of the PCB board 12 to achieve a locking effect, so that the plastic shell 13 is fixedly installed on the PCB board 12. In other words, the plastic shell 13 can be stably installed on the PCB board 12, and the lower end face of the pad 133 abuts against the upper surface of the PCB board 12, thereby ensuring that the height and relative position of the plug 131 of the plastic shell 13 are in the predetermined position, so that it will not touch the fiber optic chip module 11 when it is installed for matching and installation later.

[0038] To make the assembly structure of the plastic shell 13 and the PCB board 12 more stable, the following design is also made: a metal locking piece 135 is inserted into the plastic shell 13. The lower end of the metal locking piece 135 is formed with two spaced spring buckles 1351. The spring buckles 1351 are placed between the first positioning buckle 1341 and the second positioning buckle 1342, and the spring buckles 1351 are fixed with the positioning lock hole 122, and the locking structure is stable.

[0039] Both sides of the upper end of the plastic shell 13 are provided with stepped grooves 136. The bottom of the stepped groove 136 is provided with a T-shaped slot 137 that passes through the lower end face of the plastic shell 13. The metal locking piece 135 is T-shaped and is inserted and fixed in the T-shaped slot 137. Its structure makes it easier to install the metal locking piece 135 and ensures that the metal locking piece 135 will not pass through the T-shaped slot 137 excessively.

[0040] The outer surface of the plastic shell 13 is provided with an outwardly protruding stop 138, and a first sealing ring 139 is provided on the outside of the stop 138. The stop 138 contacts the outer edge of the stepped perforation of the product shell (such as the camera shell) to achieve the function of positioning and installation, and the first sealing ring 139 contacts the inner wall of the stepped perforation to achieve the effect of sealing assembly. The front end of the plastic shell 13 is also provided with a foolproof guide rib 130. The function of the foolproof guide rib 130 is that when the female connector 1 and the male connector 2 are inserted, the foolproof guide rib 130 aligns with the rib groove of the male connector 2 to achieve the function of foolproofing, and at the same time, it can also enhance the insertion and extraction force.

[0041] This utility model also includes a male connector 2 adapted to the female connector 1, the male connector 2 comprising:

[0042] Insulating cylinder 21;

[0043] The insert rear cover 22 is located at the front end of the insulating cylinder 21;

[0044] The insert holder 23 is fixed to the front end of the insert rear cover 22, and the insert holder 23 has a first mating hole 231 and a second mating hole 232 along its front end to the rear.

[0045] The fiber optic ceramic ferrule assembly 24 is inserted and fixed in the ferrule rear cover 22. The front end of the fiber optic ceramic ferrule assembly 24 is exposed outside the front end of the ferrule rear cover 22 and is inserted into and exposed in the first mating hole 231. The fiber optic cable 240 connected to the rear end of the fiber optic ceramic ferrule assembly 24 extends out of the insulating cylinder 21.

[0046] Male terminal 25, the front end of which passes through and is exposed in the second mating hole 232.

[0047] After the male connector 2 is inserted into the female connector 1, the front end of the fiber optic ceramic ferrule assembly 24 can be inserted into the slot 112 of the light guide section 111, ensuring the stability and alignment of the insertion, making the optical signal transmission more stable and of higher quality. A gap is formed between the front end of the fiber optic ceramic ferrule assembly 24 and the bottom of the slot 112, preventing collision and further ensuring the quality of optical transmission.

[0048] The following is a detailed description of the specific structure of the fiber optic ceramic ferrule assembly 24.

[0049] The fiber optic ceramic ferrule assembly 24 includes: a ceramic ferrule 241, a ceramic tail shank 242 disposed at the rear end of the ceramic ferrule 241, a flexible tube 243 sleeved around the rear end of the ceramic tail shank 242, a fixing tube 244 sleeved around the ceramic tail shank 242 and the flexible tube 243, a riveting cylinder 245 riveting the outside of the fixing tube 244 and the outside of the optical fiber 240, and a spring 246 disposed between the ceramic tail shank 242 and the fixing tube 244. The fixing tube 244 is fixedly inserted into the ferrule rear cover 22, which enables the entire fiber optic ceramic ferrule assembly 24 and the ferrule rear cover 22 to form a stable assembly. The riveting cylinder 245 rivets the outside of the fixing tube 244 and the outside of the optical fiber 240 together, so that the fiber optic ceramic ferrule assembly 24 and the optical fiber 240 form a stable connection.

[0050] The optical fiber 240 passes through the ceramic tail shank 242, the ceramic ferrule 241, the flexible tube 243, and the fixing tube 244, and extends out of the insulating cylinder 21.

[0051] The ferrule 23 has a sliding groove 233 on its rear side. An inner convex flange 234 is provided between the sliding groove 233 and the first mating hole 231. A first inclined pressing surface 2340 with an inclination angle of 50°-70° is provided on the side of the inner convex flange 234 near the sliding groove 233. Preferably, the inclination angle of the first inclined pressing surface 2340 is 60°. Correspondingly, the front end of the ceramic tail shank 242 is provided with a second inclined pressing surface 2420 adapted to the first inclined pressing surface 2340. Preferably, the inclination angle of the second inclined pressing surface 2420 is 60°. The size 420 is smaller than the size of the first inclined pressing surface 2340; the second inclined pressing surface 2420 of the ceramic tail shank 242 contacts the first inclined pressing surface 2340 under the elastic force of the spring 246, and the second inclined pressing surface 2420 and the first inclined pressing surface 2340 can move relative to each other in the radial direction, which allows the fiber optic ceramic ferrule assembly 24 to be finely adjusted relative to the first mating hole 231, and has a tolerance function, so that when the optical guide part 111's mating slot 112 is inserted into the front end of the fiber optic ceramic ferrule assembly 24 later, the optical guide part 111's mating slot 112 will not be damaged, thus ensuring product quality.

[0052] The upper end of the ferrule cover 22 is provided with a first limiting groove 221. The wire 250 connected to the rear end of the male terminal 25 is pressed into and fixed in the first limiting groove 221, which ensures the stability of the assembly structure.

[0053] A sealing plug 211 is inserted into the rear end of the insulating cylinder 21, and an end cap 212 is fixedly connected to the rear end of the insulating cylinder 21. The end cap 212 confines the sealing plug 211 to the rear end of the insulating cylinder 21, thereby improving the sealing and waterproof performance. The sealing plug 211 has a first through hole 201 and a second through hole 202. The end cap 212 has a third through hole 203 and a fourth through hole 204 corresponding to the first and second through holes 201 and 202, respectively. The wire 250 and the optical fiber 240 are respectively inserted and fixed in the first and second through holes 201 and 202, forming an interference fit assembly, thus achieving a sealed assembly with excellent waterproof performance. The wire 250 and the optical fiber 240 extend out of the end cap 212 through the third and fourth through holes 203 and 204. The sealing plug 211 is preferably made of rubber.

[0054] The male connector 2 also includes a plastic outer shell 27, which is fitted and fixed to the outside of the insulating cylinder 21. It forms an interlocking space 270 for fitting with the front end of the plastic shell 13. A second sealing ring 213 is provided around the insulating cylinder 21. The second sealing ring 213 is located in the interlocking space 270 and is used to form a sealed assembly with the female connector 1 to improve the waterproof performance of the product.

[0055] The plastic outer shell 27 and the insulating cylinder 21 are fixed together by a snap-fit ​​structure.

[0056] The plastic outer shell 27 is provided with an elastic locking plate 271, and the front end of the elastic locking plate 271 is provided with a locking slot 272; the front end of the plastic shell 13 is provided with a buckle 101. After the plastic shell 13 and the plastic outer shell 27 are inserted into each other, the buckle 101 and the locking slot 272 lock and fix them, so that the male head 2 and the female seat 1 form a stable assembly and are not easy to accidentally detach.

[0057] In summary, in this utility model, the fiber optic chip module 11 used in the female connector 1 is directly fixed on the PCB board 12, and then the plastic shell 13 with the female connector terminal 14 fixed on it is directly installed on the PCB board 12. The plastic shell 13 does not contact the fiber optic chip module 11, so it will not damage the fiber optic chip module 11 and ensure the quality of the fiber optic chip module 11. The light guide part 111 of the fiber optic chip module 11 is exposed in the connector 131 of the plastic shell 13 and is used to transmit optical signals with the male connector 2 inserted into the connector 131. The plastic shell 13 covers the fiber optic chip module 11, thereby protecting the fiber optic chip module 11. The entire female connector 1 has a very simple structure, few parts, and a relatively small overall size, making it suitable for scenarios with limited installation space.

[0058] Example 2:

[0059] The difference between this second embodiment and the first embodiment described above is as follows:

[0060] In this second embodiment, combined with Figure 11-14 As shown, the female connector 1 is a force-type female connector, that is, the light guide part 111 is vertically distributed, and the insertion direction of the slot 112 is perpendicular or nearly perpendicular to the PCB board 12.

[0061] Furthermore, each group of positioning buckles 134 includes a first positioning buckle 1341 and a second positioning buckle 1342 that are spaced apart, with no metal locking piece between them, making the structure simpler.

[0062] Apart from the differences described above, the other structures of this embodiment two are basically the same as the other structures of the above embodiment one, and will not be described in detail here.
