Description

Technical Field

[0001] This invention relates to the field of optical fiber communication technology, and more specifically to a connector with a built-in pull cord and an optical fiber connection assembly. Background Technology

[0002] With the rapid development of the communications industry, signal connectors such as optical connectors and electrical connectors have been widely used. As standard connectors, optical connectors and electrical connectors are used in considerable quantities due to their small size and ease of operation.

[0003] With the large-scale deployment of FTTH (Fiber To The Home), pre-connected products that reduce construction costs, lower technical requirements, and simplify installation are becoming increasingly popular. Firstly, externally mounted pull cords result in larger diameters, significantly impacting the density of the duct pulling box, necessitating a reduction in connector size. Secondly, externally mounted pull cords expose the connection points directly, making them prone to aging, breakage, and functional failure; therefore, the pull cord connection points require protection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the first aspect of this invention provides a connector with a built-in pull cord, which can reduce the size of the connector.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0006] A connector built into a pull cord, comprising:

[0007] The connector body is fitted with a connector housing.

[0008] A pull cord is fitted onto the connector body and is directly or indirectly connected to the connector housing.

[0009] In some embodiments, the radial dimension of the pull cord does not exceed the radial dimension of the connector housing.

[0010] In some embodiments, the pull cord includes:

[0011] A flange portion, which is fitted inside the connector housing and connected to the inner wall of the connector housing;

[0012] The main body is connected to the flange portion and forms a first stepped surface with the flange portion, wherein the radial dimension of the first stepped surface does not exceed the radial dimension of the connector housing.

[0013] In some embodiments, one of the flange and the connector housing is provided with a slot, and the other is provided with a snap that engages with the slot.

[0014] In some embodiments, the flange and the connector housing are connected by threads.

[0015] In some embodiments, it further includes a limiting member for pressing against the main body at a set stroke of the pull cord.

[0016] In some embodiments, the limiting member is a second stepped surface disposed on the connector body;

[0017] Alternatively, the connector may further include a connector tail sleeve, which is fitted onto the connector body, and the limiting member is a second stepped surface provided on the connector tail sleeve.

[0018] In some embodiments, the main body also includes a pull cord with anti-slip texture.

[0019] In some embodiments, the flange and connector housing are provided with positioning structures for installation.

[0020] A second aspect of the invention provides another connector with a built-in pull cord, which allows for a reduction in the size of the connector.

[0021] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0022] A connector built into a pull cord, comprising:

[0023] The connector body is fitted with a connector housing.

[0024] A pull cord is directly fitted onto the connector body and is directly or indirectly connected to the connector housing, and the radial dimension of the pull cord does not exceed the radial dimension of the connector housing.

[0025] A third aspect of the present invention provides an optical fiber connection assembly comprising any of the aforementioned drawstring-embedded connectors.

[0026] Compared with the prior art, the advantages of the present invention are as follows:

[0027] The pull cord-integrated connector of this invention includes a connector body and a pull cord component. A connector housing is fitted onto the connector body. The pull cord component is fitted onto the connector body and is directly or indirectly connected to the connector housing. In this invention, the pull cord component is fitted onto the connector body. It is understood that the radial dimension of the connector body is smaller than the radial dimension of the connector housing. Compared to the prior art's external solution where the pull cord component is fitted onto the connector housing, the overall radial dimension of the connector can be reduced, thereby allowing for the arrangement of more connectors within a limited space to meet current needs.

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] See Figure 1 As shown, this application embodiment provides a connector with a built-in pull rope, which includes a connector body 1 and a pull rope component 2.

[0036] The connector body 1 is fitted with a connector housing 11; the pull rope 2 is fitted on the connector body 1 and is directly or indirectly connected to the connector housing 11.

[0037] Understandably, in a connector, the component with the largest overall radial dimension is the connector housing 11. In existing technologies with externally mounted pull cords, the pull cord is typically fitted onto the outer wall of the connector housing, thus determining the final radial dimension of the connector. However, in the embodiments of this application, the pull cord 2 is fitted onto the connector body 1. It is worth noting that the radial dimension of the connector body 1 is smaller than that of the connector housing 11. Therefore, the pull cord 2, designed in this way, has a smaller impact on the overall size of the connector compared to existing externally mounted pull cord solutions.

[0038] In some preferred embodiments, the radial dimension of the pull cord 2 does not exceed the radial dimension of the connector housing 11. That is, the radial dimension of the connector is ultimately determined by the connector housing 11, which undoubtedly reduces the overall radial dimension compared to the prior art where it is determined by the pull cord.

[0039] The following is a specific example to illustrate this:

[0040] In a specific implementation, the rope member 2 includes a flange portion 21 and a main body portion 22.

[0041] The flange portion 21 is sleeved inside the connector housing 11 and is connected to the inner wall of the connector housing 11;

[0042] The main body 22 is connected to the flange 21 and forms a first stepped surface 221 with the flange 21. The radial dimension of the first stepped surface 221 does not exceed the radial dimension of the connector housing 11.

[0043] It is understood that, because the flange 21 in this embodiment of the invention is sleeved inside the connector housing 11 and connected to the inner wall of the connector housing 11, it is equivalent to being partially housed inside the connector housing 11, which can reduce the overall radial dimension of the connector. At the same time, since the pull cord 2 is partially located inside the connector housing 11, it can also reduce environmental corrosion, better protect the pull cord 2, and extend its service life.

[0044] The first stepped surface 221 abuts against the end of the connector housing 11, and the two are consistent in overall radial dimension. That is, in this embodiment of the invention, the pull cord 2 engages with the inner wall of the connector housing 11 through a flange portion 21 with a radial dimension smaller than that of the connector housing 11. Simultaneously, the radial dimension of the main body 22 is ensured not to exceed the radial dimension of the connector housing 11. Thus, the overall size of the connector is determined by the radial dimension of the outermost connector housing 11. In the prior art, the pull cord is external, fitted onto the outer wall of the connector housing 11, so the overall size of the connector is determined by the radial dimension of the pull cord. It is understood that, with connector housings 11 of the same size, the connector in this embodiment of the invention will be smaller.

[0045] In some embodiments, one of the flange portion 21 and the connector housing 11 is provided with a snap 3, and the other is provided with a slot 4 that engages with the snap 3.

[0046] See Figure 2 and Figure 3As shown, when a snap-fit ​​method is used for fixing, a buckle 3 can be provided on the flange portion 21, and a slot 4 that engages with the buckle 3 can be provided on the connector housing 11. It can be understood that the slot and buckle can also be provided on the flange portion 21 with a buckle and on the connector housing 11 with a slot, and this embodiment of the invention does not limit this.

[0047] Of course, other connection methods can also be used as needed. For example, internal and external threads can be provided on the pull rope 2 and the connector housing 11 respectively for connection. Bonding, laser welding, thermal welding and other methods can also be used for connection. This invention does not limit the methods.

[0048] In some embodiments, a limiting member 6 is also included for pressing against the main body 22 at a set stroke of the pull rope 2.

[0049] Specifically, the limiting member 6 is a second stepped surface disposed on the connector body 1.

[0050] Or, see Figure 5 As shown, the connector also includes a connector tail sleeve 5, which is sleeved on the connector body 1, and the limiting member 6 is a second stepped surface provided on the connector tail sleeve 5.

[0051] When the pull cord is built-in, it may fall off when the pull cord is pulled. To solve this problem, in this embodiment of the invention, a second stepped surface is formed on the connector body 1 or the connector tail sleeve 5. When the pull cord 2 drives the connector housing 11 to slide along the axial direction of the connector body 1, the second stepped surface can act as a limiting surface to hold the pull cord 2 in place, so that the pull cord 2 has no space to deform inward, thus preventing the pull cord 2 from falling off.

[0052] In some embodiments, the main body 22 further includes a pull cord 222, which has anti-slip textures 223. The pull cord 222 facilitates operation of the pull cord component 2 to unlock the device, and the anti-slip textures 223 on the pull cord 222 prevent slippage when pulling, providing a better user experience.

[0053] See Figure 4 As shown, when the pull cord 2 is pulled, the buckle 3 on the pull cord 2 and the slot 4 of the connector housing 11 are subjected to force, causing the connector housing 11 to move backward and compress the spring 7, thereby unlocking the adapter and connector. When the force on the pull cord 2 is released, the spring 7 drives the connector housing 11 forward to reset.

[0054] In some embodiments, the flange 21 and the connector housing 11 are provided with positioning structures for installation. The positioning structures facilitate easier mating and correction during blind mating.

[0055] In summary, the pull cord-integrated connector of this invention includes a connector body 1 and a pull cord component 2. A connector housing 11 is fitted onto the connector body 1. The pull cord component 2 is fitted onto the connector body 1 and is directly or indirectly connected to the connector housing 11. In this invention, the pull cord component 2 is fitted onto the connector body 1. It is understood that the radial dimension of the connector body 1 is smaller than the radial dimension of the connector housing 11. Compared with the prior art's external solution where the pull cord component 2 is fitted onto the connector housing 11, the overall radial dimension of the connector can be reduced, thereby allowing for the arrangement of more connectors within a limited space to meet current needs.

[0062] Furthermore, the pull rope component 2 includes:

[0063] The flange portion 21 is fitted inside the connector housing 11 and is connected to the inner wall of the connector housing 11;

[0064] The main body 22 is connected to the flange 21 and forms a first stepped surface 221 with the flange 21. The radial dimension of the first stepped surface 221 does not exceed the radial dimension of the connector housing 11.

[0065] Furthermore, one of the flange portion 21 and the connector housing 11 is provided with a buckle 3, and the other is provided with a slot 4 that mates with the slot.

[0066] Furthermore, the flange 21 and the connector housing 11 are connected by threads.

[0067] Furthermore, it also includes a limiting member 6 for pressing against the main body 22 at the set stroke of the pull rope member 2.

[0068] Furthermore, the limiting member 6 is a second stepped surface disposed on the connector body 1;

[0069] Alternatively, the connector may further include a connector tail sleeve 5, which is fitted onto the connector body 1, and the limiting member 6 is a second stepped surface provided on the connector tail sleeve 5.

[0070] Furthermore, the main body 22 also includes a pull rope 222, which has anti-slip texture 223.

Compared with the prior art's external solution where the pull cord component 2 is fitted onto the connector housing 11, the overall radial dimension of the connector can be reduced, thereby allowing more connectors to be arranged within a limited space to meet current needs.
