Description

Technical Field

[0001] Embodiments of this disclosure generally relate to the field of connector technology, and more specifically, to a cable clamp for a wired connector, and a wired connector including the cable clamp. Background Technology

[0002] A wire connector mainly includes a housing, terminals at least partially located within the housing, and a cable connected to the terminals, wherein the end of the cable away from the terminals extends to the outside of the housing through a through cavity. To improve the sealing performance of the wire connector, a single-wire seal (SWS) is typically provided between each cable and the housing. In the prior art, to protect the single-wire seal, a clamp is usually provided on the wire connector housing. However, existing clamps can only be applied to wire connectors with a single row of terminals. For wire connectors with multiple rows of terminals, the cable connected to the middle row of terminals cannot be fitted with a clamp. If a separate clamp is designed for each cable, not only is assembly time-consuming, but the small size also makes assembly inconvenient. Utility Model Content

[0003] This disclosure is made in order to overcome at least one of the above-mentioned and other problems and defects existing in the prior art.

[0004] According to one aspect of this disclosure, a cable clamp for a wired connector is provided, the cable clamp including a first clamping member and a second clamping member detachably connected together, the first clamping member and the second clamping member clamping the cable from opposite sides of a row of cables of the wired connector, the first clamping member and the second clamping member connected together forming a row of through holes for the cable to pass through, wherein the first clamping member includes a first base and a mating groove formed in the first base, and the second clamping member includes a second base and a mating portion extending from the second base, the mating portion being slidable along the axial direction of the through holes toward the mating groove to engage with the mating groove, thereby connecting the first clamping member and the second clamping member together.

[0005] According to an exemplary embodiment of the present disclosure, the dimension of the insertion slot of the first base on the side closer to the second base is smaller than the dimension of the insertion slot on the side farther from the second base.

[0006] According to an exemplary embodiment of this disclosure, the insertion slot is in the form of a blind slot.

[0007] According to an exemplary embodiment of the present disclosure, the first base is formed with a first groove, and the second base is formed with a second groove. When the first clamping member and the second clamping member are connected together, the first groove and the second groove constitute the through hole through which the cable passes.

[0008] According to an exemplary embodiment of the present disclosure, the cable clamp further includes a cylindrical wrapping portion extending from the first base and the second base along the axial direction of the through hole, the cylindrical wrapping portion being configured to be inserted into the through cavity and wrapping around the outside of the cable.

[0009] According to an exemplary embodiment of the present disclosure, the insertion portion includes a first semi-cylindrical wrapping portion extending from the first base along the axial direction of the through hole and a second semi-cylindrical wrapping portion extending from the second base along the axial direction of the through hole. When the first clamping member and the second clamping member are connected together, the first semi-cylindrical wrapping portion and the second semi-cylindrical wrapping portion constitute the cylindrical wrapping portion.

[0010] According to an exemplary embodiment of the present disclosure, the first base and the second base are respectively provided with protrusions at both ends along the arrangement direction of a row of through holes for interfering with the housing of the wire connector.

[0011] According to another aspect of this disclosure, a wired connector is provided, the wired connector comprising: a housing containing terminals; a cable, one end of which is connected to the terminals, and the other end of which extends through a through cavity in the housing to the outside of the housing; and a cable clamp employing the cable clamp described in the above embodiments.

[0012] According to an exemplary embodiment of the present disclosure, the wire connector further includes a plastic encapsulation covering the housing and the cable clamp.

[0013] According to the cable clamps and wired connectors described in the various embodiments of this disclosure, the first and second clamping members of the cable clamp clamp each clamp and wrap the cables in each row of through-cavities of the multi-row through-cavities of the wired connector. This prevents external foreign objects from entering the through-cavities through the gap between the through-cavities and the cables and damaging the SWS (Wire Support Sealing System) within the through-cavities, thereby achieving the protection function for the SWS corresponding to these cables. Furthermore, the cable clamp can also reduce the tensile force on the terminals when the cables are subjected to external pulling forces, improving the retention force of the terminals within the connector housing.

[0014] Other objects and advantages of this disclosure will become apparent from the following description of the disclosure with reference to the accompanying drawings, and will help to provide a comprehensive understanding of the disclosure. Attached Figure Description

[0020] Furthermore, in the following detailed description, numerous specific details are set forth for ease of explanation to provide a thorough understanding of embodiments of the present disclosure. However, it will be apparent that one or more embodiments may be practiced without these specific details. In other instances, well-known structures and apparatuses are illustrated to simplify the figures.

[0022] Furthermore, the terminology used herein is for describing exemplary embodiments and is not intended to limit and / or constrain this disclosure. Unless the context clearly indicates otherwise, the singular forms “a,” “an,” and “the,” “the” are also intended to include the plural forms. In this disclosure, the terms “comprising,” “including,” “having,” and similar terms are used to enumerate features, quantities, steps, operations, elements, components, or combinations thereof, but do not exclude the presence or addition of one or more of said features, quantities, steps, operations, elements, components, or combinations thereof.

[0023] Although the terms “first,” “second,” etc., may be used herein to describe a variety of different elements, these elements should not be limited by these terms. These terms are used only to distinguish one element from another. For example, without departing from the scope of this disclosure, a first element may be referred to as a second element, and a second element may be referred to as a first element. The term “and / or” includes a combination of multiple related items or any one of multiple related items.

[0024] According to the general inventive concept of this disclosure, a cable clamp for a wired connector is provided. The cable clamp includes a first clamping member and a second clamping member detachably connected together, the first clamping member and the second clamping member clamping the cable from opposite sides of a row of cables of the wired connector, respectively. The first clamping member and the second clamping member, connected together, together form a row of through holes for the cable to pass through. The first clamping member includes a first base and a insertion slot formed in the first base. The second clamping member includes a second base and a insertion portion extending from the second base. The insertion portion is slidable along the axial direction of the through holes toward the insertion slot to engage with the insertion slot, thereby connecting the first clamping member and the second clamping member together.

[0025] According to another general inventive concept of this disclosure, a wired connector is also provided. The wired connector includes: a housing containing terminals; a cable, one end of which is connected to the terminals, and the other end of which extends through a through-cavity in the housing to the outside of the housing; and a cable clamp, which is a cable clamp as described above.

[0026] like Figure 8 As shown, a wired connector typically includes a connector housing 200 and a plurality of terminals (not shown) at least partially disposed within the connector housing 200. The terminals are arranged in multiple rows, each terminal being connected to a cable 300. The connector housing 200 also includes multiple rows of through-cavities 201, through which the cables 300 connected to each row of terminals extend from inside the connector housing 200 through a corresponding row of through-cavities 201 to the outside of the connector housing 200. Single-wire seals (SWS) may, for example, be placed in these through-cavities 201 to provide a seal between each cable 300 and the connector housing 200.

[0027] like Figures 1 to 3As shown, the wired connector according to this disclosure also includes a cable clamp 100, which includes a first clamping member 10a and a second clamping member 10b detachably connected together. The first clamping member 10a and the second clamping member 10b are respectively configured to clamp the cables 300 from opposite sides of a row of cables 300 of the wired connector. The first clamping member 10a and the second clamping member 10b connected together form a row of through holes 12 for the cables 300 to pass through. The first clamping member 10a includes a first base 11a and a insertion groove 13 formed in the first base 11a. The second clamping member 10b includes a second base 11b and an insertion portion 16 extending from the second base 11b. The insertion portion 16 is slidable toward the insertion groove 13 along the axial direction of the through hole to insert into the insertion groove 13, thereby connecting the first clamping member 10a and the second clamping member 10b together. In use, the cables 300 in each row of through-cavities 201 of the multi-row through-cavities 201 of the wired connector can be clamped and wrapped by the first clamping member 10a and the second clamping member 10b of the cable clamp 100, respectively. This prevents external foreign objects from entering the through-cavity 201 through the gap between the through-cavity 201 and the cable 200 and damaging the SWS inside the through-cavity 201, thereby achieving the protection function of the SWS corresponding to these cables 300. In addition, the cable clamp can also reduce the tensile force on the terminals when the cable is pulled by external force, improve the holding force of the terminals in the connector housing, and prevent the terminals from coming off due to excessive external force. This cable clamp can be used not only for wired connectors with a single row of through-cavities, but also for wired connectors with multiple rows of through-cavities. Furthermore, since a single cable clamp can protect the SWS in a row of through-cavities, it can improve assembly efficiency, reduce manufacturing costs, and avoid the defects of small size and inconvenient installation caused by using a single clamp to protect a single SWS.

[0028] It should be noted that in some other embodiments of this disclosure, the insertion slot 13 may also be formed on the second base 11b, and correspondingly, the insertion portion 16 that mates with the insertion slot 13 is formed on the first base 11a. Furthermore, other methods may be used to detachably connect the first clamping member 10a and the second clamping member 10b together, such as snap-fit ​​connections.

[0029] According to exemplary embodiments of this disclosure, such as Figures 1 to 3As shown, the dimension of the insertion groove 13 of the first base 11a of the cable clamp 100 near the second base 11b is smaller than the dimension of the insertion groove 13 away from the second base 11b. That is, the insertion groove 13 has a dovetail shape in a plane perpendicular to the axial direction of the through hole 12 to prevent the first base 11a and the second base 11b from separating in the plane perpendicular to the axial direction of the through hole 12. It should be noted that in other embodiments of this disclosure, the insertion groove 13 may also take other forms, such as a rectangular shape.

[0030] According to exemplary embodiments of this disclosure, such as Figures 1 to 3 As shown, the insertion groove 13 is in the form of a blind groove. That is, the insertion groove 13 is formed by a recess on the side of the first base 11a away from the connector housing 200. In other words, the insertion groove 13 does not penetrate the first base 11a in the axial direction of the through hole 12, which can further improve the protection performance and sealing function of the cable clamp 100.

[0031] According to exemplary embodiments of this disclosure, such as Figures 1 to 3 As shown, a first base 11a has a first groove 12a, and a second base 11b has a second groove 12b. When the first clamping member 10a and the second clamping member 10b are connected together, the first groove 12a and the second groove 12b constitute a through hole 12 for the cable 300 to pass through. In this embodiment, the cross-sections of the first groove 12a and the second groove 12b are semi-circular to accommodate the cable 300, which has a circular cross-section. When the cross-section of the cable is of another shape, such as an elliptical shape, the cross-sections of the first groove 12a and the second groove 12b are correspondingly replaced with a semi-elliptical shape.

[0032] According to exemplary embodiments of this disclosure, such as Figures 1 to 3 As shown, the cable clamp 100 also includes a cylindrical wrapping portion 15 extending from the first base 11a and the second base 11b along the axial direction of the through hole 12. The cylindrical wrapping portion 15 is configured to be inserted into the through cavity 201 and to wrap the outside of the cable 300, so as to further prevent foreign objects from entering the through cavity 201 through the gap between the through cavity 201 and the cable 300 and causing damage to the SWS. Specifically, the insertion portion 16 includes a first semi-cylindrical wrapping portion 15a extending from the first base 11a along the axial direction of the through hole 12 and a second semi-cylindrical wrapping portion 15b extending from the second base 11b along the axial direction of the through hole 12. When the first clamping member 10a and the second clamping member 10b are connected together, the first semi-cylindrical wrapping portion 15a and the second semi-cylindrical wrapping portion 15b constitute the cylindrical wrapping portion 15. The inner contour of the cylindrical wrapping part 15 is approximately adapted to the outer dimensions of the cable 300, and the outer contour of the cylindrical wrapping part 15 is approximately adapted to the diameter of the through cavity 201 through which the cable 300 passes.

[0033] According to exemplary embodiments of this disclosure, such as Figures 1 to 3 As shown, the first base 11a and the second base 11b are respectively provided with protrusions 14 at both ends along the arrangement direction of the row of through holes 12 for interfering with the connector housing 200. By providing the protrusions 14 to interfere with the connector housing 200, the first clamping member 10a and the second clamping member 10b of the cable clamp 100 can be held on the connector housing 200 to prevent the cable clamp 100 from falling off the connector housing 200 before plastic sealing.

[0034] According to another aspect of this disclosure, a wire connector is also provided, such as Figure 8 As shown, the wired connector includes: a housing 200, which houses a terminal block; a cable 300, one end of which is connected to the terminal block, and the other end of which extends to the outside of the housing 200 via a through cavity 201 on the housing 200; and a cable clamp, which is a cable clamp 100 as described above.

[0035] According to an exemplary embodiment of the present disclosure, the wire connector also includes a plastic encapsulation (not shown) encapsulating the housing 200 and the cable clamp 100.

[0036] Figures 4 to 8 The diagram schematically illustrates the installation steps of a cable clamp 100 for a wired connector according to an exemplary embodiment of the present disclosure. First, the first base 11a of the first clamping member 10a is abutted against one side of a row of cables 300, such that the first groove 12a on the first base 11a engages with the row of cables 300, as shown below. Figure 4 As shown; then, the second base 11b of the second clamping member 10b is placed against the other side of the row of cables 300, such that the second groove 12b on the second base 11b engages with the row of cables 300, as shown. Figure 5 As shown; then, the first clamping member 10a and the second clamping member 10b are connected together by inserting the insertion slot 13 on the first base 11a and the insertion portion 16 on the second base 11b together, as shown. Figure 6 As shown; then, as Figure 7 As shown, the first clamping member 10a and the second clamping member 10b, which are connected together, are pressed towards the through cavity 201 on the connector housing 200, so that the cylindrical wrapping portion 15 of the cable clamp 100 is inserted into the through cavity 201 on the connector housing 200. At the same time, the protrusions 14 on both ends of the first base 11a and the second base 11b interfere with the housing 200, thereby stably fixing the cable clamp 100 to the connector housing 200, thus realizing the installation of the cable clamp. Finally, cable clamps are installed on the other rows of cables 300 of the connector, such as... Figure 8 As shown.

[0037] According to the cable clamps and wired connectors described in the various embodiments of this disclosure, the first and second clamping members of the cable clamp clamp each clamp and wrap the cables in each row of through-cavities of the multi-row through-cavities of the wired connector. This prevents external foreign objects from entering the through-cavities through the gap between the through-cavities and the cables and damaging the SWS (Wire Support Sealing System) within the through-cavities, thereby achieving the protection function for the SWS corresponding to these cables. Furthermore, the cable clamp can also reduce the tensile force on the terminals when the cables are subjected to external pulling forces, improving the retention force of the terminals within the connector housing.

[0038] Although embodiments of the present disclosure have been shown and described, it will be understood by those skilled in the art that variations may be made to these embodiments without departing from the principles and spirit of the present disclosure, the scope of which is defined by the appended claims and their equivalents. Furthermore, it should be noted that, unless otherwise specified, the terms “comprising,” “including,” and “having” as used herein do not exclude other elements or steps. Additionally, any reference numerals in the claims should not be construed as limiting the scope of the present disclosure.
