Description

Technical Field

[0001] This utility model relates to the field of patch cord connection technology, specifically to patch cord connector structure. Background Technology

[0002] When connecting cable patch cord connectors, tools are needed to remove the cable sheath and then crimp the terminals onto the cable using crimping pliers. However, this method requires specialized skills and tools, resulting in low installation efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a jumper connector structure that improves the installation efficiency of cables and connectors by modifying the jumper connector structure.

[0004] To achieve the above objectives, this utility model provides a jumper connector structure, including a first housing portion having a wire groove, a second housing portion connected to the first housing portion, and a conductor disposed in the second housing portion. The conductor forms a piercing end for piercing the cable sheath, and at least a portion of the piercing end is located within the wire groove.

[0005] By setting a piercing end located within the cable groove, the stripping operation of the cable is replaced, improving the installation efficiency of the cable and patch cord connector structure.

[0006] Optionally, each puncture end is provided with at least two tips along the extension direction of the groove, with the tips spaced apart along the extension direction of the groove. By providing two tips, a redundancy mechanism is introduced during the puncture process, ensuring the overall success rate of the puncture process.

[0007] Optionally, the tips belonging to the same puncture end are staggered along the width of the cable groove. This creates two staggered puncture positions inside the cable groove along its width, thereby further increasing the contact area and reliability between the cable and the conductor.

[0008] Optionally, a recess is formed between two adjacent tips to allow a portion of the wire core to pass through. The recess provides a channel for the cable, allowing a portion of the wire core to serpentine around the recess under the influence of the two tips, thereby further increasing the contact area between the cable and the conductor.

[0009] Optionally, each tip has a first inclined surface and a second inclined surface, wherein the second inclined surface has a larger inclination angle than the first inclined surface;

[0010] The first bevel of one of two adjacent tips and the second bevel of the other are located on the same side of the conductor along the width of the slot.

[0011] In this way, during the process of piercing the cable, the same strand of wire can be split twice under the action of the two tips and separated into different positions on each tip, thereby further increasing the contact area and contact strength between the wire and the tip.

[0012] Optionally, the second shell portion forms a slot for insertion into the first shell portion, with the piercing end located within the slot.

[0013] Optionally, it also includes a plug-in portion for fixing the conductor, and the second housing portion has a slot adapted to the plug-in portion. By providing the plug-in portion, quick insertion and connection of the conductor and the second housing portion is achieved.

[0014] Optionally, the first shell and the second shell are engaged.

[0015] The connection between the first shell and the second shell is achieved by inserting the first shell into the second shell and snapping them together, which replaces the traditional method of using crimping pliers to install cables and connectors, thus improving installation efficiency.

[0016] Optionally, the second shell portion is provided with a first shell section and a second shell section connected to each other, the first shell section being provided with a slot and the second shell section being provided with a locking arm.

[0017] By designing the second shell into a first shell section with a socket and a second shell section with a locking arm, the connector achieves integrated optimization of cable docking function and mechanical locking function for external termination, significantly improving the ease of operation and connection reliability of the connector structure.

[0018] Optionally, it also includes a shielding layer that surrounds the first housing segment and the first housing portion. By providing the shielding layer, the portion where the conductor and cable are connected can be shielded and protected.

[0019] Optionally, the patch cord connector configuration is used for terminating a single pair of Ethernet connections.

[0020] This structure enables efficient installation of patch cord connectors through a termination design optimized for single-pair Ethernet connections.

Detailed Implementation

[0035] This utility model provides a jumper connector structure, which improves the installation efficiency of cables and connectors by modifying the structure of the jumper connector.

[0036] To enable those skilled in the art to better understand the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] Relational terms such as “first” and “second” are used merely to distinguish one component from another that has the same name, without necessarily requiring or implying any such actual relationship or order between the components.

[0039] To achieve the above objectives, this utility model provides a patch cord connector structure. The patch cord connector is used to mate with cable 7 and terminate it with an external structure. The patch cord connector structure can be applied to the termination of single-pair Ethernet connections. This structure achieves efficient installation of the patch cord connector through a termination design optimized for single-pair Ethernet connections.

[0040] like Figure 1 , Figure 2 As shown, the jumper connector structure includes a first housing 1 with a wire groove 10, a second housing 2 connected to the first housing 1, and a conductor 3 disposed in the second housing 2. The conductor 3 forms a piercing end 31 for piercing the outer sheath of the cable 7, and at least a portion of the piercing end 31 is located within the wire groove 10.

[0041] Combination Figure 1 , Figure 2 as well as Figure 3 and Figure 4 As shown, both the first shell 1 and the second shell 2 are integrally molded from insulating material. A groove 10 for accommodating the cable 7 is formed in the first shell 1. The groove 10 penetrates a portion of the surface of the first shell 1 to form a groove-like structure with an opening for inserting the piercing end 31 (described later). The groove 10, extending axially along the cable 7, penetrates the first shell 1 in its extending direction to allow the cable 7 to enter through one side of the groove 10 and exit through the other side. The piercing end 31 is formed on a conductor 3 for external conduction between the cable 7 and the connector structure. The conductor 3 is disposed in the second shell 2, which supports and fixes the conductor 3. After the first shell 1 and the second shell 2 are connected, all or part of the piercing end 31 enters the groove 10 to pierce the outer sheath of the cable 7 located within the groove 10. This replaces the stripping operation of the cable 7 in related technologies, improving the installation efficiency of the cable 7 and the jumper connector structure.

[0042] As an optional example, such as Figures 1-4 As shown, conductor 3 extends approximately along the length of the connector structure (axial direction of cable 7), and the portion of conductor 3 near cable 7 is provided with the aforementioned piercing end 31. The piercing end 31 can pierce cable 7 axially or radially and contact the wire core within cable 7. Cable 7 includes several copper wires, which serve as the wire core. The wire core can also be made of other materials capable of electrical conduction.

[0043] In such Figure 2 and Figure 5 In the example shown, the piercing end 31 pierces the cable 7 radially through the opening, which optimizes the compactness of the connector structure.

[0044] like Figure 5 As shown, the portion of the second shell 2 with the piercing end 31 forms a slot 21a. The slot 21a penetrates a portion of the surface of the second shell 2 to form an insertion port, and the piercing end 31 located within the slot 21a can be exposed to the outside through the insertion port. The first shell 1 is inserted into the slot 21a through the insertion port along the insertion direction. This enables rapid assembly of the first shell 1 and the second shell 2. The insertion direction can be along the axial direction of the cable 7 or along the radial direction of the cable 7.

[0045] In a specific example as shown in the figure, the first shell portion 1 is inserted radially into the second shell portion 2 along the cable 7, while the piercing end 31 is inserted radially into the slot 21a. The first shell portion 1 and the second shell portion 2, after insertion, can form a regular structure. For example, the inserted portion of the first shell portion 1 and the second shell portion 2 can form an approximately rectangular structure. Of course, it can also form a regular structure such as a cylinder or a cone to facilitate the installation of the shielding layer portion 4, which will be described later.

[0046] The first shell 1 and the second shell 2, after insertion, form a fixed connection using a snap-fit ​​method. The first shell 1 is inserted into the second shell 2, and the connection is achieved through a snap-fit. This replaces the traditional method of using crimping pliers to install the cable 7 and connector, improving installation efficiency. Other connection methods can also be used. When using the snap-fit ​​method, a snap protrusion and a snap recess are required at the overlapping portion of the first shell 1 and the second shell 2 to achieve the snap-fit. The snap protrusion and the snap recess can be formed by injection molding the first shell 1 and the second shell 2.

[0047] For further details, please continue to see [link / reference]. Figure 5 To ensure the insertion accuracy of the first shell 1 and the second shell 2, one of them is provided with a guide groove, and the other is provided with a guide protrusion. The guide groove and the guide protrusion can also be formed at the designated positions of the first shell 1 and the second shell 2 by injection molding.

[0048] As a more concrete example, in... Figure 4 In the example shown, the slot wall of the slot 21a has a guide hole 21b, which extends along the insertion direction and penetrates the slot wall of the slot 21a. A protruding ridge 11 formed on the first housing portion 1 is adapted to the guide hole 21b, and the protruding ridge 11 is adapted to the guide hole 21b. The protruding ridge 11 extends along... Figure 4 The upper and lower directions are respectively located on the two surfaces of the first shell 1 and are adapted to the guide holes 21b one by one. The upper and lower directions are perpendicular to the insertion direction.

[0049] In the example shown, the second housing 2 has a first housing segment 21 and a second housing segment 22 distributed longitudinally along the length of the connector structure. The first housing segment 21 is located on the rear side of the second housing segment 22, that is, closer to the cable 7. The first housing segment 21 is provided with the aforementioned slot 21a. The portion of the conductor 3 located inside the second housing segment 22 extends from the second housing segment 22 to the first housing segment 21, and the portion located inside the second housing segment 22 is exposed as a pin to terminate with an external socket. The second housing segment 22 is provided with a locking arm 22a for locking with the external socket termination.

[0050] By designing the second shell section 2 into a split design consisting of a first shell section 21 with a socket and a second shell section 22 with a locking arm 22a, the connection function with the cable 7 and the mechanical locking function with external termination are integrated and optimized, significantly improving the ease of operation and connection reliability of the connector structure.

[0051] In such Figure 4 In the example shown, the socket and the locking arm 22a are located on different surfaces of the second housing 2. The locking arm 22a is located on... Figure 4 The upper surface of the second shell portion 2, and the insertion port is formed in Figure 4 The side surface of the middle. When inserting the first housing 1 and the second housing 2, it can prevent damage to the locking arm 22a caused by gripping it.

[0052] like Figures 2 to 6 As shown, to achieve a fixed connection between the conductor 3 and the second housing 2, a plug-in portion 5 is fixedly connected to the middle of the conductor 3. A piercing end 31 protrudes from the rear of the plug-in portion 5, and a portion of the conductor 3 protrudes from the front of the plug-in portion 5. The plug-in portion 5 is made of insulating material and is integrally molded with the conductor 3 to form an integrated module. A mounting groove for inserting the plug-in portion 5 is formed in the second section of the second housing 2. The mounting groove and the plug-in portion 5 are inserted along the axial direction of the connecting cable 7, or alternatively, radially. By providing the plug-in portion 5, quick insertion of the conductor 3 into the second housing 2 is achieved.

[0053] In such Figure 7 and Figure 8In the example shown, the connector structure also includes a shielding layer 4, which wraps around the first housing section 21 and the first housing section 1. By providing the shielding layer 4, the portion where the conductor 3 and the cable 7 are connected can be shielded and protected.

[0054] As an example, the shielding layer 4 is divided into two or more interlocking shielding plates 41, which together form a whole that encloses the first shell segment 21 and the first shell part 1. The first shell segment 21 and the first shell part 1, after being inserted, form a regular rectangular structure. The outer wall of the first shell part 1 of the first shell segment 21 also has a snap-fit ​​structure for engaging with the corresponding shielding plates 41. The shielding plates 41 engage with the corresponding first shell segment 21 and first shell part 1.

[0055] Alternatively, the shielding sheet 41 may not be snapped into the first shell section 21 and the first shell portion 1, but rather the shielding sheet 41 itself forms a snap-fit ​​structure. This snap-fit ​​structure can be located on the surfaces where the two shielding sheets 41 meet, thus reducing the thickness of the shielding layer portion 4; alternatively, to simplify processing precision, such as... Figure 5 and Figure 6 In the example shown, at least a portion of the two shielding plates 41 overlap, and the snap-fit ​​structure is disposed in the overlapping area of ​​the two shielding plates 41.

[0056] In addition to this method, the shielding layer 4 can also be a pre-processed integral structure that can be directly fitted onto the regularly shaped part formed by the first shell segment 21 and the first shell part 1 to achieve the wrapping of that part.

[0057] As an alternative, the rear section of the shielding layer 4 extends rearward to form a securing section 42 for wrapping the outside of the cable 7. The securing section 42 forms a cylindrical structure to fit over the outside of the cable 7, which on the one hand can support the cable 7 in the axial direction to prevent the portion of the cable 7 that is not inserted into the slot 21a from squeezing or dragging the cable 7 inside the slot 21a; on the other hand, it can prevent excessive bending at the root of the cable 7 from causing damage to the cable 7.

[0058] In the aforementioned examples, the connector structure also includes an outer protective sleeve 6, which covers the outer side of the wire fixing portion 42 and the shielding layer portion 4. After the shielding layer is assembled with the first shell portion 1 and the second shell portion 2, the shielding layer, the first shell portion 1, and part of the second shell portion 2 are potted with adhesive, and then the outer protective sleeve 6 is fitted into the corresponding position.

[0059] The structure of the puncture end 31 is illustrated below. The structure of the puncture end 31 can be used in the various embodiments described above or applied to a scheme composed of any two or more of the aforementioned embodiments.

[0060] Please see Figure 9 and Figure 10Along the extension direction of the groove 10, each puncture end 31 is provided with at least two tips 31a, and the tips 31a are spaced apart along the extension direction of the groove 10.

[0061] By setting two tips 31a, a redundancy mechanism is introduced during the puncture process, ensuring the overall success rate of the puncture process.

[0062] In the example shown, the piercing end 31 has two tips 31a for piercing the outer sheath of the cable 7. The tips 31a are machined by processes such as cutting. The two tips 31a are spaced apart along the extension direction of the cable groove 10, that is, along the axial direction of the cable 7. By setting the tips 31a, stress concentration points can be formed when piercing the outer sheath of the cable 7. After piercing the outer sheath, it can be inserted into the subsequent wire core. At this time, part of the outer sheath is pierced, while the remaining outer sheath still covers the wire core. In this way, the wire core can contact the piercing end 31 under the action of the outer sheath to achieve conductivity.

[0063] In a more specific example, the piercing end 31 is spaced apart from both ends of the cable groove 10 to pierce the middle of the cable 7.

[0064] In such Figure 9 or Figure 10 In this example, the tips 31a belonging to the same puncture end 31 are staggered along the width direction of the groove 10. In this way, two staggered puncture positions can be formed inside the cable 7 in the width direction of the groove 10, thereby further increasing the contact area and contact reliability between the cable 7 and the conductor 3.

[0065] To achieve radial staggering in the cable 7, as an example, each tip 31a has a first inclined surface 31a-1 and a second inclined surface 31a-2, with the second inclined surface 31a-2 having a larger inclination angle than the first inclined surface 31a-1; the first inclined surface 31a-1 of one of two adjacent tips 31a and the second inclined surface 31a-2 of the other are located on the same side of the conductor 3 along the width direction of the groove 10.

[0066] The body portion of the piercing end 31 with the tip 31a is aligned axially, but each tip 31a is machined with a first inclined surface 31a-1 and a second inclined surface 31a-2 with different inclinations, i.e., the two inclined surfaces shown in the figure. Other inclined surfaces are also provided in a direction not visible in the figure, which, together with the first inclined surface 31a-1 and the second inclined surface 31a-2, constitute the tip 31a. Alternatively, the body portion of the piercing end 31 with the tip 31a can be radially offset; those skilled in the art can choose accordingly.

[0067] In this way, during the process of piercing the cable 7, the same strand of wire can be split twice under the action of the two tips 31a and separated on different sides of each tip 31a, thereby further increasing the contact area and contact strength between the wire and the tip 31a.

[0068] In the aforementioned technical solution, a recess 31b is formed between two adjacent tips 31a. The recess 31b is located between two body portions provided with tips 31a, and the depth of the recess 31b can be equal to, less than, or greater than the radial dimension of the cable 7. The recess 31b provides a channel for the cable 7, allowing a portion of the cable 7's core to serpentinely bypass the recess 31b under the action of the two tips 31a, thereby further increasing the contact area between the cable 7 and the conductor 3.

[0069] Below Figure 9 and Figure 10 Based on this, the piercing state of the piercing portion of the present application on the cable 7 will be described. In this embodiment, the main body is spaced apart and opposite to each other along the axial direction, and two tips 31a at different positions are formed by processing inclined surfaces with different tilt angles, as shown in the figure. These are defined as the first tip 31a and the second tip 31a, respectively.

[0070] During the process of piercing the outer sheath at the piercing end 31, the first tip 31a divides the cores belonging to the same strand into a first core and a second core with multiple cores. The second tip 31a is radially offset from the first tip 31a, which can further divide the first core into a first sub-strand and a second sub-strand. Assuming that the second sub-strand merges with the second core, the second sub-strand that overlaps with the second core has one pierced side that passes through the recess 31b to the other side of the piercing end 31, passing through the piercing end 31 in a serpentine shape, thereby further increasing the contact area with the piercing end 31.

[0071] Of course, besides this method, the outer sheath of the cable 7 can also be pierced by using a single tip 31a or multiple tips 31a aligned axially. Those skilled in the art can choose according to their needs.

[0072] This article uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the core ideas of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made to this utility model without departing from the principles of this utility model, and these improvements and modifications also fall within the protection scope of the claims of this utility model.
