Description

Technical Field

[0001] This utility model relates to the field of cable connectors, and more particularly to a snap-fit ​​structure and a cable connector. Background Technology

[0002] The signal connection between the first and second cables is achieved through the interaction between the RJ45 connector and the cable connector. The cable connector consists of a housing and a gland hinged to the housing. Depending on the gland, they are classified as 90° or 180° cable connectors, with the 90° connector having only one gland hinged to the housing. Due to space constraints, sufficient space must be reserved for the ferrule, resulting in particularly thin sidewalls for both the housing and the gland. Therefore, a fastening assembly is typically used to secure both the housing and the gland. However, this fastening structure leads to excessively long cable connectors, unsuitable for some applications. Even with some snap-fit ​​mechanisms to engage the housing and gland, existing mechanisms suffer from issues such as occupying extra space or difficulty in separation. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a snap-fit ​​structure and a cable connector. The snap-fit ​​structure can fix the housing body and the cover without the need for additional fastening components, thereby reducing the length of the cable connection. At the same time, because the snap-fit ​​structure enables the housing body and the cover to be disassembled, it facilitates the assembly of the cable connector.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a snap-fit ​​structure for snapping together the housing body and the pressure cap, wherein one end of the pressure cap is hinged to the housing body, the snap-fit ​​structure includes two spring arms extending downward along the side of the pressure cap away from the hinge end, the two spring arms are spaced apart along a first direction, each spring arm has a slot opened from its inner end facing the inside of the spring arm, the slot only penetrates the outer side of the spring arm, the two side walls of the housing body have grooves corresponding to the spring arms opened at the front end facing the inside of the housing body in a second direction, and the bottom of the groove is provided with a hook that can be embedded in the slot.

[0005] The beneficial effects of this utility model are as follows:

[0006] The snap-fit ​​structure is integrated into the structure of the housing body and the gland itself, requiring no additional structure.

[0007] Instead of thickening the sidewalls of the shell body, a hook is directly set on the sidewalls of the shell body. In order to cooperate with this hook without increasing the thickness of the spring arm, compared with the conventional slot structure, the slot on the spring arm only penetrates the outer side of the spring arm. This type of slot structure meets the snap-fit ​​requirements within the existing space without affecting the strength, and meets the strength requirements when the slot snaps in.

[0008] Furthermore, when the hook and the slot are engaged, a gap exists between the lower end face of the spring arm away from the pressure cap and the lower side wall of the groove away from the pressure cap. This gap allows an external tool to be inserted, at which point the external tool can pry the spring arm to separate it from the hook.

[0009] Furthermore, the thickness of the spring arm in the first direction is greater than the thickness of the side wall of the housing body in the first direction, thereby meeting the requirements for the slot. When the hook and the slot are engaged, the outer side of the spring arm does not protrude from the side wall of the housing body, and the engagement of the spring arm and the hook does not affect the width of the housing formed in the first direction.

[0010] Furthermore, the lower end face of the spring arm is inclined, and the lower end face of the spring arm slopes downward from the side near the inner end face of the spring arm to the side away from the inner end face of the spring arm. The inclined lower end face of the spring arm abuts against the external tool, which facilitates the application of force by the external tool to separate the spring arm and the hook.

[0011] Furthermore, the lower sidewall of the groove is a plane.

[0012] Furthermore, the lower sidewall of the groove is inclined, and the inclination direction is consistent with the inclination direction of the lower end face of the spring arm. The inclined lower sidewall of the groove makes it easier for external tools to be inserted into the gap.

[0013] Furthermore, the hook includes a transition slope at the upper end and a snap-fit ​​surface at the lower end. The transition slope slopes downwards towards the side away from the bottom of the groove. The transition slope facilitates the engagement of the cap and the hook during assembly. As the cap is pressed down, the transition slope makes way for the spring arm, allowing the spring arm of the upper cap to snap into the hook along the transition slope, thus completing the closure of the cap and the housing body.

[0014] Furthermore, the pressure cap and the spring arm are integrally formed, providing strength to the spring arm.

[0015] This utility model also discloses a cable connector, including a housing body and a pressure cover, wherein the housing body and the pressure cover are snapped together by the above-mentioned fastening structure.

[0016] Furthermore, a direct-pressure insert is provided in the cavity formed by the housing body and the pressure cap. Attached Figure Description

[0028] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0029] In the diagrams below, the first direction is the X direction, the second direction is the Y direction, and the up and down direction is the Z direction.

[0030] The present invention provides a snap-fit ​​structure for snapping together a housing body 1 and a pressure cap 2, wherein one end of the pressure cap 2 is hinged to the housing body 1, and the snap-fit ​​structure is located on the side away from the hinge.

[0031] The housing body 1 and the cover 2 form a 90° cable connector housing. At this time, the direct-pressure ferrule needs to enter the housing body 1 horizontally. Therefore, the distance between the two side walls 1a of the housing body 1 in the X direction must meet the entry of the direct-pressure ferrule. At the same time, due to the usage environment of the cable connector, the overall space occupied by the housing body 1 in the X direction cannot be too large. Therefore, the side wall 1a of the housing body 1 is usually only a few millimeters thick.

[0032] The fastening structure is provided on the structure of the housing body 1 and the pressure cover 2, without the need for additional structures.

[0033] See appendix Figure 1 Appendix Figure 2 and attached Figure 4 As shown, the fastening structure includes two spring arms 3 extending downward along the side of the pressure cap 2 away from the hinge end, and the two spring arms 3 are spaced apart along a first direction. Each spring arm 3 has a slot 3a formed from its inner end face 31 into the interior of the spring arm 3, and the slot 3a only penetrates the outer side surface 32 of the spring arm 3 (the outer side surface 32 is the side of the two spring arms 3 facing away from each other). See Appendix Figure 6 As shown, the two side walls 1a of the housing body 1 are provided with grooves 12 corresponding to the spring arm 3 on the front end face 11 in the second direction. The bottom of the groove 12 is provided with a hook 121 that can be embedded in the slot 3a.

[0034] In this embodiment, there is no need to thicken the side wall 1a of the housing body 1. Instead, a hook 121 is directly provided on the side wall 1a of the housing body 1. At the same time, in order to cooperate with this hook 121 without increasing the thickness of the spring arm 3, compared with the conventional slot 3a structure with four sides and one bottom surface, see Appendix Figure 5 As shown, the slot 3a on the spring arm 3 only penetrates the outer side 32 of the spring arm 3. At this time, the slot 3a has three sides and one bottom surface. The slot 3a has two openings. This structure of the slot 3a meets the snap-fit ​​requirements in the existing space without affecting the strength, and meets the strength requirements when the slot 3a is snapped.

[0035] Furthermore, in this embodiment, because the spring arm 3 and the hook 121 are engaged, i.e., detachably connected, the cover 2 can be flipped multiple times to meet assembly requirements. When it is necessary to fix the cable, the spring arm 3 and the hook 121 are engaged; when it is necessary to adjust the cable, the hook 121 is disengaged from the slot 3a.

[0036] See appendix Figure 2 As shown, the thickness of the spring arm 3 in the first direction is greater than the thickness of the side wall 1a of the housing body 1 in the first direction. This is because the side wall 1a of the housing body 1 is only a few millimeters thick, and if the spring arm 3 is too small, the slot 3a cannot be formed. However, it is necessary to ensure that when the hook 121 and the slot 3a are engaged, the outer surface 32 of the spring arm 3 does not protrude from the side wall 1a of the housing body 1, that is, it will not affect the width of the housing formed by the engagement in the first direction.

[0037] To facilitate the separation of the hook 121 and the slot 3a using external tools. In one embodiment, when the hook 121 and the slot 3a are engaged, see attached diagram. Figure 2As shown, a gap 4 is left between the lower end face 33 of the spring arm 3 away from the pressure cover 2 and the lower side wall 122 of the groove 12 away from the pressure cover 2. This gap 4 allows an external tool (such as a screwdriver) to be inserted, at which time the external tool can pry the spring arm 3 to separate the spring arm 3 from the hook 121.

[0038] In one embodiment, see Appendix Figure 2 As shown, the lower end face 33 of the spring arm 3 is inclined, and the lower end face 33 of the spring arm 3 slopes downward from the side near the inner end face 31 of the spring arm 3 to the side away from the inner end face 31 of the spring arm 3. After the external tool is inserted into the gap 4, it is lifted upward to make the pressure cover 2 flip upward. The inclined lower end face 33 of the spring arm 3 abuts against the external tool, which facilitates the application of force by the external tool to separate the spring arm 3 from the hook 121.

[0039] In one embodiment, see Appendix Figure 3 As shown, the lower sidewall 122 of the groove 12 is a plane.

[0040] In one embodiment, see Appendix Figure 2 As shown, the lower sidewall 122 of the groove 12 is inclined, and the inclination direction is consistent with the inclination direction of the lower end face 33 of the spring arm 3. The inclined lower sidewall 122 of the groove 12 makes it easier for external tools to be inserted into the gap 4. The inclination angle of the lower sidewall 122 of the groove 12 and the inclination angle of the lower end face 33 of the spring arm 3 can be the same or different.

[0041] See appendix Figure 3 As shown, the hook 121 includes a transition slope 1211 at the upper end and a snap-fit ​​surface 1212 at the lower end. The transition slope 1211 slopes downwards towards the side away from the bottom of the groove 12. The transition slope 1211 facilitates the engagement of the cover 2 and the hook 121. When the cover 2 is pressed down, the transition slope 1211 makes way for the spring arm 3, allowing the spring arm 3 of the upper cover 2 to snap into the hook 121 along the transition slope 1211, thus completing the closure of the cover 2 and the housing body 1.

[0042] In one embodiment, the spring arm 3 and the pressure cap 2 are integrally formed.

[0043] Because the spring arm 3 is made of metal, the longer the spring arm 3 is, the greater its elasticity, and the less wear it causes to the latch 121. However, the final housing height in the Z direction is subject to industry limitations, so the length of the spring arm 3 should be increased as much as possible.

[0044] One end of the pressure cap 2 is provided with a hinge shaft, and the housing itself has an insertion hole for the hinge shaft to be inserted and rotated.

[0045] In one embodiment, a cable connector is also disclosed, including a housing body 1 and a pressure cap 2, wherein the housing body 1 and the pressure cap 2 are snapped together by the aforementioned fastening structure. A direct-pressure insert is disposed within the cavity formed by the housing body 1 and the pressure cap 2.

[0046] Because this direct-pressure insert is used, there must be sufficient space between the side walls 1a of the housing body 1. However, due to space constraints, the housing cannot be enlarged further; therefore, the side walls 1a of the housing body 1 are typically only a few millimeters thick. The snap-fit ​​structure in this embodiment is located on these few-millimeter-thick side walls 1a, achieving a detachable snap-fit ​​connection between the cover 2 and the housing body 1 without increasing the cable connector's width in the X direction.

[0047] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
