[0023] Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0024] Example 1: See Figure 1 Embodiment 1 of this utility model provides a pin-reinforced optoelectronic adapter, including an optical fiber coupling tube 1 and two contact assemblies 2 disposed on both sides of the optical fiber coupling tube 1. The optical fiber coupling tube 1 is used to couple the optical fibers of connectors and other components to realize the transmission of optical signals. Each contact assembly 2 includes a first contact 20 and at least one second contact 21. In one embodiment, the first contact 20 and the second contact 21 can be arranged flush along the length of the optical fiber coupling tube 1. The first contact 20 and the second contact 21 are connected to the circuit board of the panel by welding. By increasing the number of contacts of the adapter, the connection between the contacts and the circuit board is made more robust, and the stability of the electrical coupling is improved.

[0025] In a preferred embodiment, see [reference] Figure 2 The first contact 20 and the second contact 21 are staggered along the length of the optical fiber coupling tube 1 to form a stable triangular structure, which further optimizes the stability of the contact between the contact and the circuit board.

[0026] Specifically, every three contacts can form a triangular structure. In one embodiment, the contact assembly 2 includes a first contact 20 and a second contact 21. Compared with the existing two-contact adapter, the connection strength between the contacts and the circuit board is increased by at least two times. The four contacts are staggered so that every three contacts can form a triangular structure. When the adapter is subjected to a large force, the contacts are not easily separated from the circuit board due to the stability of the triangular structure, and the connection is more stable.

[0027] See Figure 3 The contact assembly 2 includes a contact body 22. In one embodiment, the first contact 20 and the second contact 21 are disposed on one side of the contact body 22. The first contact 20 and the second contact 21 are alternately disposed on one side of the contact body 22, and there is a certain distance between the first contact 20 and the second contact 21 in the cross-sectional direction of the optical fiber coupling tube 1, which facilitates subsequent soldering of the contact to the circuit board.

[0028] In another embodiment, the first contact 20 and the second contact 21 are disposed on both sides of the contact body 22 (not shown in the figure). The first contact 20 and the second contact 21 are staggered from each other in the cross-sectional direction of the optical fiber coupling tube 1 to facilitate subsequent soldering of the contact to the circuit board.

[0029] Since existing two-touch adapters have a certain market share, in order to be compatible with existing adapters, the second contact 21 can be separated from the contact body 22 so that the photoelectric adapter can be adapted to panels with different numbers of contacts.

[0030] To separate the second contact 21 from the contact body 22, please refer to [the document / reference needed]. Figure 3 At least one notch 210 is provided on the second contact piece 21 near the contact piece body 22. The notch 210 is used to cut the second contact piece 21 off the contact piece body 22. In one embodiment, the number of notches 210 is set to one. The notch 210 is located on one side of the second contact piece 21. In actual use, the notch 210 can be semi-circular, triangular or rectangular, etc. The shape and size of the notch 210 are selected according to the actual use scenario.

[0031] In a preferred embodiment, the number of notches 210 is set to two, respectively disposed on both sides of the second contact piece 21, so as to facilitate the separation of the second contact piece 21 from the contact piece body 22, wherein the shape and size of the notches 210 are selected according to the actual use scenario.

[0032] In another embodiment, the second contact piece 21 is detachably disposed on the contact piece body 22. The second contact piece 21 has snap-fit ​​protrusions (not shown in the figure) on both side walls. Two connecting arms (not shown in the figure) extend from the contact piece body 22. The distance between the two connecting arms is the same as the width of the second contact piece 21, allowing the second contact piece 21 to be accommodated between the two connecting arms. The connecting arms can elastically deform under the pressure of the snap-fit ​​protrusions, and a fixing groove is provided at the corresponding position of each connecting arm. The fixing groove is used to accommodate and fix the snap-fit ​​protrusions, so that the second contact piece 21 can be fixed together with the contact piece body 22.

[0033] See Figure 4 In order to transmit electrical signals, the contact body 22 includes a connecting plate 23 and a snap-fit ​​plate 24 connected at a preset angle. One end of the connecting plate 23 is provided with a contact and the other end is provided with a first conductive terminal 230. One end of the snap-fit ​​plate 24 is provided with a second conductive terminal 240. The first conductive terminal 230 and the second conductive terminal 240 are used to achieve electrical coupling with the connector.

[0034] In one embodiment, the connecting plate 23 and the snap-fit ​​plate 24 are orthogonally arranged. The second contact 21 and the first contact 20 are disposed on one side of the connecting plate 23 to transmit electrical signals with the panel. A first conductive terminal 230 is disposed on the other side of the connecting plate 23, and a second conductive terminal 240 is disposed on the snap-fit ​​plate 24 on the same side as the first conductive terminal 230. The first conductive terminal 230 and the second conductive terminal 240 abut against the connector to realize the transmission of electrical signals between the connector and the adapter. Since the connecting plate 23 and the snap-fit ​​plate 24 are connected together, the panel, the adapter and the connector can realize the transmission of electrical signals.

[0035] See Figure 5 In order to fix the contact assembly 2, the photoelectric adapter also includes a housing 3. The contact body 22 is disposed inside the housing 3. A first fixing hole 300 and a second fixing hole 301 are provided on the bottom plate 30 of the housing 3. The first fixing hole 300 is used to accommodate the first contact 20, and the second fixing hole 301 is used to accommodate the second contact 21.

[0036] Each contact assembly 2 corresponds to a first fixing hole 300 and a second fixing hole 301 to accommodate the corresponding contact.

[0037] Specifically, see Figure 6 and Figure 7 The outer shell 3 includes a front shell 33 and a rear shell 34, which are connected together by a snap-fit ​​structure. The front shell 33 includes the base plate 30.

[0038] In one embodiment, the snap-fit ​​structure includes at least one snap-fit ​​member 330 and at least one snap-fit ​​groove 340, with the snap-fit ​​member 330 and the corresponding snap-fit ​​groove 340 corresponding one-to-one. The snap-fit ​​member 330 is disposed at the tail end of the front housing 33, and the snap-fit ​​groove 340 is disposed at the front end of the rear housing 34. The snap-fit ​​member 330 is accommodated and fixed in the snap-fit ​​groove 340 to fix the front housing 33 and the rear housing 34.

[0039] The front housing 33 has a first opening 331 and a second opening 332 at its tail end, and the rear housing 34 has a first protrusion 341 and a second protrusion 342 at its front end. When the front housing 33 and the rear housing 34 are fixed together, the first protrusion 341 is accommodated in the first opening 331, and there is a preset distance between the front sidewall of the first protrusion 341 and the front sidewall of the first opening 331 to form a first fixing hole 300, in which the first contact piece 20 is accommodated; the second protrusion 342 is accommodated in the second opening 332, and there is a preset distance between the front sidewall of the second protrusion 342 and the front sidewall of the second opening 332 to form a second fixing hole 301, in which the second contact piece 21 is accommodated.

[0040] It should be noted here that, with Figure 6 For example, the tail end of the front housing 33 refers to the right end of the front housing 33, and the front end of the rear housing 34 refers to the left end of the rear housing 34. In this embodiment, the front and rear ends are based on... Figure 6 The directions shown are described only for the convenience of describing the present invention and are not intended to require the present invention to be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0041] See Figure 8 The outer casing 3 has a guide groove 32 on its side wall, which is used to accommodate the contact body 22.

[0042] Specifically, the guide groove 32 is disposed on the side wall of the front housing 33. In one embodiment, since the connecting plate 23 and the snap-fit ​​plate 24 are orthogonally arranged, the guide groove 32 is configured as an L-shaped groove to accommodate the contact body 22. Specifically, a fixing seat 302 is disposed on the bottom plate 30, and there is a preset distance between the fixing seat 302 and the bottom plate 30 to form an accommodating space for accommodating the connecting plate 23. A groove is disposed on the inner side wall of the outer housing 3 to accommodate the snap-fit ​​plate 24, so that the contact body 22 can be accommodated in the guide groove 32.

[0043] In order to achieve electrical coupling between the panel and the optoelectronic adapter, the first contact 20 is exposed from the first fixing hole 300 and the second contact 21 is exposed from the second fixing hole 301 to connect to the contacts on the panel.

[0044] In one embodiment, the first conductive terminal 230 and the first contact piece 20 are disposed on the same longitudinal axis. The contact piece assembly 2 is pushed from the tail end of the front housing 33 into the guide groove 32. The lower surface of the connecting plate 23 is attached to the upper surface of the base plate 30, and the inner sidewall of the snap-fit ​​plate 24 is attached to the sidewall of the fixing seat 302 to accommodate the contact piece body 22 in the guide groove 32. The first contact piece 20 is accommodated in the first opening 331, and the second contact piece 21 is accommodated in the second opening 332. After the front housing 33 and the rear housing 34 are snapped together, the first contact piece 20 is exposed from the first fixing hole 300, and the second contact piece 21 is exposed from the second fixing hole 301 to be soldered to the circuit board.

[0045] The notch 210 should be provided on the lower surface of the base plate 30 to prevent the notch 210 from being exposed from the second fixing hole 301, which would cause the second contact piece 21 to be accidentally broken.

[0046] See Figure 9 The bottom of the outer casing 3 is provided with at least one pair of clips 31, which are used to snap and fix with the panel. Specifically, the clips 31 are provided at the bottom of the rear casing 34. In order to ensure the fixing effect, in a preferred embodiment, the bottom of the outer casing 3 is provided with two pairs of clips 31. When the contact piece and the circuit board are soldered together, the clips 31 are snapped onto the panel to fix the photoelectric adapter to the panel, thereby further improving the stability of the connection between the panel and the photoelectric adapter.

[0047] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
