Technical Field

[0001] This utility model relates to a quick-release communication connector. Background Technology

[0002] Communication connectors are interconnecting devices for network transmission media, and the performance of the connectors used can affect the entire communication system. There are many models and standards for communication connectors, mainly including fiber optic connectors and electrical connectors. Connectors bridge gaps in circuits or between isolated circuits, allowing current to flow and enabling the circuit to perform its intended function.

[0003] Connectors typically consist of terminals, terminal housings fixed to the outside of the terminals, and an outer shell that surrounds the terminal housings. The outer shell is usually made of plastic or metal. However, in the prior art, the outer shell is usually composed of multiple parts, which are connected and fixed by screws. In actual use, due to the influence of the working environment, the screws that fix the outer shell are prone to rusting due to moisture and sticking to the outer shell. When the internal terminals are damaged and need to be replaced, it is often not easy to disassemble the outer shell.

[0004] Therefore, a quick-release communication connector is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a quick-release communication connector to solve the problem mentioned in the background art that the screws fixing the outer shell are prone to rusting due to moisture and sticking to the outer shell, and that it is often not easy to disassemble the outer shell when the internal terminals are damaged and need to be replaced.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a quick-release communication connector, including a terminal housing, a lower housing disposed on the outer side of the terminal housing, and an upper housing disposed on top of the lower housing, the lower housing and the upper housing being connected by fixing bolts.

[0007] The upper and lower housings are engaged and connected.

[0008] The front ends of the lower housing and the upper housing are provided with connecting rings for fixing the connector to the external wiring harness.

[0009] Both the lower housing and the upper housing have anti-slip retaining rings inside their tail ends for securing the terminal housings.

[0010] Preferably, the lower housing includes a housing base located at the bottom of the terminal housing, and connecting grooves are provided on both sides of the housing base.

[0011] Preferably, the top of the housing base is provided with a storage groove, and two sets of spring plates are symmetrically arranged in the storage groove, wherein one set of spring plates consists of two spring plates.

[0012] Preferably, the housing base has two sets of positioning holes on both sides of its tail end.

[0013] Preferably, the upper housing includes a housing cover and a connecting plate, the connecting plate being formed at the bottom end of the housing cover, and the configuration of the connecting plate matching the connecting groove.

[0014] Preferably, there are two sets of connecting plates, which are symmetrically arranged on both sides of the bottom of the upper housing, and threaded holes are provided on the side of the connecting plates.

[0015] Preferably, the upper housing further includes positioning pins, and two sets of positioning pins are provided, with the two sets of positioning pins respectively located on both sides of the tail end of the upper cover of the housing.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. This utility model features an upper housing, a lower housing, and fixing bolts. The upper and lower housings are joined together by connecting plates and connecting slots, and the connecting plates and connecting slots are fixed by the fixing bolts on both sides. This allows the upper and lower housings to form the outer shell of a connector, which is nested outside the terminal housing. When disassembly is required, the fixing bolts can be rotated and removed to release the fixation between the upper and lower housings. Simultaneously, the spring force of the spring plate on the top of the lower housing lifts the upper housing, causing the upper and lower housings to separate automatically. The upper housing can then be removed, allowing for the replacement of the internal terminal housing and terminals, thus achieving quick disassembly.

[0019] 2. The present invention includes a fixing bolt comprising a bolt body and a rubber washer. The rubber washer is located on the inner side of the bolt body and contacts the side wall of the housing base during installation. The rubber washer is compressed and generates elastic force during the tightening of the fixing bolt, making the threaded connection between the fixing bolt and the housing base tighter. At the same time, the rubber washer provides isolation, preventing the connection between the fixing bolt and the housing base from getting damp and rusting, thereby extending the service life.

[0029] To address the problem that screws securing the outer casing are prone to rusting and sticking to the casing due to moisture, and that disassembling the casing is often difficult when internal terminals need replacement, this utility model provides a quick-release communication connector. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Please see Figure 1-8 This utility model provides a quick-release communication connector, including a terminal housing 1, a lower housing 2 disposed on the outer side of the terminal housing 1, and an upper housing 3 disposed on the top of the lower housing 2. The lower housing 2 and the upper housing 3 are connected by fixing bolts 4.

[0031] The upper housing 3 and the lower housing 2 are engaged and connected. The front ends of the lower housing 2 and the upper housing 3 are provided with connecting rings 5 ​​for fixing the connector to the external wiring harness.

[0032] Both the lower housing 2 and the upper housing 3 have anti-slip retaining rings 6 inside their tail ends to secure the terminal housing 1. The anti-slip retaining rings 6 secure the terminal housing 1 installed between the lower housing 2 and the upper housing 3, preventing the terminal housing 1 from loosening.

[0033] The lower housing 2 includes a housing base 21 located at the bottom of the terminal housing 1, and connecting grooves 22 are provided on both sides of the housing base 21.

[0034] The top of the housing base 21 has a storage groove, and two sets of spring plates 23 are symmetrically arranged in the storage groove, wherein each set of spring plates 23 consists of two spring plates. The spring plates 23 are designed in an arc shape, and the top of the spring plates 23 is higher than the plane of the top of the housing base 21. When the upper housing 3 and the lower housing 2 are combined, they are pressed into the storage groove.

[0035] The housing base 21 has two sets of positioning holes 24 on both sides of its tail end.

[0036] The upper housing 3 includes a housing cover 31 and a connecting plate 32. The connecting plate 32 is formed at the bottom end of the housing cover 31, and its configuration matches the connecting groove 22. During installation, the two sets of connecting plates 32 are inserted into the inside of the connecting groove 22. When the upper housing 3 and the lower housing 2 are closed, the threaded holes on the side of the connecting plate 32 are aligned with the threaded holes on the side of the connecting groove 22. At this time, the connecting plate 32 and the connecting groove 22 are connected and fixed by inserting fixing bolts 4, thereby fixing the upper housing 3 to the top of the lower housing 2.

[0037] Two sets of connecting plates 32 are provided, and the two sets of connecting plates 32 are symmetrically arranged on both sides of the bottom of the upper housing 3. Threaded holes are opened on the side of the connecting plates 32.

[0038] The upper housing 3 also includes positioning pins 33, of which two sets are provided, and the two sets of positioning pins 33 are respectively located on both sides of the tail end of the upper cover 31. During installation, the two sets of positioning pins 33 are respectively inserted into the two sets of positioning holes 24. The connection between the positioning pins 33 and the positioning holes 24 aligns the tail ends of the upper housing 3 and the lower housing 2, preventing misalignment during installation.

[0039] The fixing bolt 4 includes a bolt body 41 and a rubber washer 42. The rubber washer 42 is located on the inner side of the bolt body 41 and contacts the side wall of the housing base 21. The rubber washer 42 is compressed and generates elastic force during the tightening of the fixing bolt 4, making the threaded connection between the fixing bolt 4 and the housing base 21 tighter. At the same time, the rubber washer 42 provides isolation to prevent the connection between the fixing bolt 4 and the housing base 21 from getting damp and rusting.

[0040] The working principle of the quick-release communication connector provided by this utility model is as follows: When in use, first rotate the bolt body 41 to make the bolt body 41 exit from the housing base 21. At this time, the connection locking state between the connecting plate 32 and the connecting groove 22 is released, and the connecting plate 32 can be pulled out from the inside of the connecting groove 22.

[0041] After the fixing bolt 4 is removed, the fixing state of the connecting plate 32 and the connecting groove 22 is released, which releases the fixed connection between the upper housing 3 and the lower housing 2. At this time, the spring plate 23 returns to its original shape under its own elasticity, and the top structure of the spring plate 23 pops out from the groove at the top of the housing base 21.

[0042] During the ejection process, the top structure of the spring plate 23 lifts the upper cover 31 of the housing, causing the upper housing 3 to separate from the lower housing 2.

[0043] Then the upper housing 3 can be removed, the terminal housing 1 installed in the lower housing 2 can be taken out, and the terminals installed in the terminal housing 1 can be disassembled and replaced. After the terminals are repaired, the terminal housing 1 with the replaced terminals is placed into the lower housing 2, the upper housing 3 is placed on top of the lower housing 2, the positioning pin 33 is aligned with the positioning hole 24, the positioning pin 33 is inserted into the positioning hole 24, and the connecting plate 32 is inserted into the connecting groove 22.

[0044] Then press the upper housing 3 and the lower housing 2 together. The pressure of the upper housing 3 on the spring plate 23 will compress the spring plate 23 into the storage groove. Then insert the fixing bolt 4 into the threaded hole on the side of the housing base 21, rotate the bolt body 41, so that the fixing bolt 4 passes through the connecting groove 22 and the connecting insert plate 32 at the same time, tighten the fixing bolt 4, and fix the connecting insert plate 32 and the connecting groove 22 through the fixing bolt 4 under the action of thread connection, thereby connecting and fixing the upper housing 3 and the lower housing 2, completing the installation of the connector housing. Finally, connect the entire connector to the wire harness to be mated by rotating the connecting ring 5.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
