Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of connecting device, especially, relate to a cable assembly, cable connector and shield sheet. BACKGROUND

[0002] When transmitting differential signals, cable connectors are needed. To ensure the accuracy of signal transmission and meet the crosstalk requirements when transmitting high-speed signals, the cable connector includes a cable shielding ground structure for shielding the cable.

[0003] For example, the Chinese invention patent application with the application publication number CN117080809A and the application publication date of November 17, 2023 discloses a cable shielding ground structure and a high-speed cable connector. The high-speed cable connector includes a cable shielding ground structure and a cable. The cable shielding ground structure includes an upper shielding sheet and a lower shielding sheet, and one end of the cable is located between the upper and lower shielding sheets. The upper shielding sheet is provided with an upper contact structure for pressing the cable shielding layer downward, and the lower shielding sheet is provided with a lower contact structure for pressing the cable shielding layer upward, so that the cable shielding layer is clamped between the upper and lower contact structures, thereby realizing the conduction of the upper and lower shielding sheets and the cable shielding layer.

[0004] When assembling the cable connector, first, the pin (i.e., the signal contact) is fixed with the insulator by injection molding, then the front end of the signal line of the cable is fixed with the pin by welding or bonding, and finally the shielding sheet is installed on the insulator. When installing the shielding sheet, if the cable is skewed, on the one hand, the contact quality of the contact structure and the cable shielding layer will be affected, and on the other hand, the fixed part of the signal line and the pin will be pulled, affecting the reliability of the cable connector.

[0005] Preferably, the upper and lower contact structures are both ground spring claws with consistent width, thereby adapting to cables of different specifications. In actual use, since the ground spring claws have a certain width in the front-to-back direction, they can to some extent right the cable, but the wider the ground spring claw, the more difficult it is to deform. When the deformation ability of the ground spring claw meets the requirements, even if the width of the ground spring claw is the largest, the ability of the ground spring claw to right the cable is still poor.

[0045] To solve the problems in the background art, the core inventive concept of the utility model is: on the basis of setting the upper contact structure and the lower contact structure, additionally adding the left grounding claw and the right grounding claw, thereby increasing the number of contact parts between the cable shielding ground structure and the cable shielding layer, and improving the reliability of the cable connector.

[0046] To facilitate the understanding of the utility model by those skilled in the art, the "up-down direction" is defined in the utility model, and the arrangement direction of the two shielding sheets is the same as the "up-down direction". In actual application, according to the cable assembly posture and the different directions of the observer, the arrangement direction of the two shielding sheets can also be the "actual direction" such as the left-right direction and the front-rear direction, at this time, the "actual direction" is taken as the "up-down direction" in the utility model. Meanwhile, the up and down in the utility model are not clearly distinguished, and the up and down can be interchanged.

[0047] The utility model will be further described in detail below in combination with embodiments.

[0048] Specific embodiment 1 of the cable connector provided by the utility model:

[0049] As shown in the figure, the cable connector includes a shell 100, a wire binding sheet 200, and eight cable assemblies 300. The wire binding sheet 200 is used to fix the shell 100 and the cable assemblies 300, and the specific fixing form can refer to the Chinese invention patent application with the application publication number CN115347406A, which will not be described here again. Among them, those skilled in the art can set the specific number of cable assemblies 300 according to actual needs. Figure 1 As shown in the figure, the cable assembly 300 includes an upper shielding sheet 1, a lower shielding sheet 5, a support plate 3, a pressing sheet 2, and a pin cable module 4. The pin cable module 4 includes a cable 41, and the cable 41 has a cable shielding layer 411. Among them, the upper shielding sheet 1, the lower shielding sheet 5, the pressing sheet 2, and the support plate 3 constitute a cable shielding ground structure.

[0050] Figures 2-10 In this embodiment, the support plate 3 and the pin cable module 4 are not improved, and the difference between the shielding sheet (upper and lower shielding sheet) in this embodiment and the existing shielding sheet (upper and lower shielding sheet) is only that the left grounding claw and the right grounding claw are additionally added to the shielding sheet in the utility model. The structure of the shielding sheet except the left grounding claw and the right grounding claw, the support plate 3, and the pin cable module 4 (including the cable 41) can refer to the Chinese invention patent application with the application publication number CN117080809A and the Chinese invention patent application with the application publication number CN115347406A.

[0051] In this embodiment, the support plate 3 and the pin cable module 4 are not improved, and the difference between the shielding sheet (upper and lower shielding sheet) in this embodiment and the existing shielding sheet (upper and lower shielding sheet) is only that the left grounding claw and the right grounding claw are additionally added to the shielding sheet in the utility model. The structure of the shielding sheet except the left grounding claw and the right grounding claw, the support plate 3, and the pin cable module 4 (including the cable 41) can refer to the Chinese invention patent application with the application publication number CN117080809A and the Chinese invention patent application with the application publication number CN115347406A.

[0052] ​As a basic implementation, the upper and lower shielding plates each include an upper and lower shielding plate body. The upper shielding plate body is connected to an upper contact structure for pressing the cable shielding layer 411 downwards, and the lower shielding plate body is connected to a lower contact structure 51 for pressing the cable shielding layer 411 upwards. The upper contact structure and the lower contact structure 51 are vertically corresponding. The upper shielding plate body and / or the lower shielding plate body are connected to a right grounding spring claw (i.e., a right contact structure) for pressing the cable shielding layer 411 to the left and a left grounding spring claw (i.e., a left contact structure) for pressing the cable shielding layer 411 to the right. The left grounding spring claw and the right grounding spring claw are horizontally corresponding. All contact structures together clamp the cable shielding layer.

[0053] For either side of the grounding spring claw 11 (left or right grounding spring claw), each side grounding spring claw 11 includes a connecting portion 113 and a conductive straightening portion for contacting and conducting with the cable shielding layer 411 and straightening the cable 41. The front-to-back dimensions of the connecting portion 113 are smaller than the front-to-back dimensions of the conductive straightening portion, and the connecting portion 113 is used to connect the conductive straightening portion to the upper shielding plate body or the lower shielding plate body. That is, the left grounding spring claw is connected to the upper shielding plate body or the lower shielding plate body, and the right grounding spring claw is connected to the upper shielding plate body or the lower shielding plate body.

[0054] Similar to the Chinese invention patent application with publication number CN117080809A, both the upper and lower contact structures can be spring claws, convex structures, or snap-fit ​​structures. Each shielding sheet is made of a conductive material (e.g., copper, aluminum, or stainless steel). After each contact structure contacts the cable shielding layer 411, each shielding sheet and the cable shielding layer 411 are electrically connected. When the cable connector is inserted into the corresponding connector, each shielding sheet shares a common ground with the corresponding cable shielding layer 411.

[0055] exist Figures 2-10 In the specific embodiment shown, both the left grounding claw and the right grounding claw are connected to the upper shielding plate body.

[0056] In other specific embodiments, the left grounding spring claw and the right grounding spring claw may both be connected to the lower shield body, or the left grounding spring claw may be connected to one of the shield bodies and the right grounding spring claw may be connected to the other shield body; or the left (right) grounding spring claw may be connected to the upper (lower) shield body and the right (left) contact structure may be a right (left) grounding convex hull or a grounding spring claw with a consistent width in the prior art.

[0057] exist Figures 2-10In the specific embodiment shown, the upper or lower contact structure 51 is a grounding spring claw connected to the corresponding shielding sheet body, and the cable assembly 300 further comprises a pressing sheet 2 for pressing the grounding spring claw to deform the grounding spring claw towards the cable shielding layer 411, the pressing sheet 2 being used to move to adjust the deformation degree of the grounding spring claw when the cable assembly 300 is assembled, and being used to be fixedly connected with the shielding sheet provided with the grounding spring claw after the grounding spring claw is deformed to the cable shielding layer 411 being clamped between the grounding spring claw and the corresponding contact structure.

[0058] The following will take the contact spring claw as the upper grounding spring claw 12 constituting the upper contact structure as an example to specifically introduce the specific embodiment shown. Figures 2-10

[0059] The pressing sheet 2 is used to press downward the upper grounding spring claw 12; before the pressing sheet 2 is fixedly connected with the upper shielding sheet 1, the deformation degree of the upper grounding spring claw 12 can be changed by moving the pressing sheet 2, so as to adjust the distance between the upper grounding spring claw 12 and the lower contact structure 51, so that the upper grounding spring claw 12 and the lower contact structure 51 can clamp more thickness (up-down size) specifications of the cable 41, and the range of the cable assembly 300 applicable to the cable 41 is improved. After the pressing sheet 2 is fixedly connected with the upper shielding sheet 1, since the pressing sheet 2 cannot move, the upper grounding spring claw 12 and the lower contact structure 51 can maintain the posture of clamping the cable 41.

[0060] It needs to be specially pointed out that the contact spring claw can also be the lower grounding spring claw constituting the lower contact structure 51, at this time, the pressing sheet 2 is used to press upward the lower grounding spring claw, and after the pressing sheet 2 is moved to the position, the pressing sheet 2 is fixedly connected with the lower shielding sheet 5.

[0061] Preferably, the pressing sheet 2 is provided with a welding hole, and the pressing sheet 2 is connected with the corresponding shielding sheet by welding through the welding hole.

[0062] The main difference between the utility model and the prior art is that in the prior art, the width (i.e. the front-back size) of the grounding spring claw is always consistent, while in the utility model, the width (i.e. the front-back size) of the connecting part 113 is smaller than the width (i.e. the front-back size) of the conducting righting part. Among them, the width of the connecting part 113 is smaller, which is easy to deform the side grounding spring claw 11, and ensures that the side grounding spring claw 11 has sufficient deformation ability; the width of the conducting righting part is larger, and the conducting righting part has better righting effect on the cable 41, thereby improving the righting ability of the left and right grounding spring claws on the cable 41.

[0063] In one specific embodiment, the conducting righting part is a rectangular sheet extending front and back, at this time, the left side wall or the right side wall of the rectangular sheet is in contact with the cable shielding layer 411. When the deflection degree of the cable 41 is larger, before the cable 41 is righted, the front and back sides of the rectangular sheet cannot be in contact with the cable shielding layer 411 at the same time, resulting in poor righting effect. ​

[0064] Preferably, in order to further side the righting effect of the elastic paw 11, the through righting part comprises two front and rear arranged elastic contact parts 111 and a transition part 112 connecting the two elastic contact parts 111, the elastic contact part 111 is used for contacting the cable shielding layer 411, and the connecting part 113 is used for connecting the transition part 112 with the corresponding shielding sheet body.

[0065] Before the cable 41 is righted, the deformation degree of the front and rear elastic contact parts 111 can be different, and when one of the elastic contact parts 111 is deformed, the other elastic contact part 111 will not move with it, thereby ensuring that the two elastic contact parts 111 can contact the cable shielding layer 411 at the same time, and improving the righting ability of the side grounding elastic paw 11.

[0066] When manufacturing the side grounding elastic paw 11, after removing the corresponding material on the sheet-shaped base material, the connecting part 113 is directly bent downward, and the through righting part is bent to form the elastic contact part 111.

[0067] Preferably, in order to further improve the righting effect on the cable 41, the left and right grounding elastic paws are connected with the same shielding sheet body, the left and right grounding elastic paws are in the shape of an outer "8", and the left and right spacing between the connecting parts 113 of the left and right grounding elastic paws is smaller than the left and right spacing between the through righting parts, at this time, the left, right, upper (lower) contact structures and the corresponding shielding sheet can be processed by the same sheet-shaped base material, which is convenient for processing and manufacturing.

[0068] In other specific embodiments, the side grounding elastic paw 11 can also be manufactured separately and welded to the corresponding shielding sheet.

[0069] When installing the shielding sheet with two side grounding elastic paws 11, since the left and right spacing between the connecting parts 113 of the left and right grounding elastic paws is smaller than the left and right spacing between the through righting parts, the side grounding elastic paw 11 is more easily moved to the two sides of the cable shielding layer 411, avoiding the side grounding elastic paw 11 directly pressing on the cable shielding layer 411, so that the side grounding elastic paw 11 can better right the cable 41.

[0070] For example, when the upper shielding sheet 1 comprises two side grounding elastic paws 11, the distance between the lower parts of the two side grounding elastic paws 11 is large to form a trumpet mouth, when moving the side grounding elastic paw 11 downward, even if the inclination angle of the cable 41 is large, the side grounding elastic paw 11 is also easily moved to the two sides of the cable shielding layer 411 (if the actual moving upper shielding sheet 1 is regarded as a reference system that does not move, it can be regarded as that the cable shielding layer 411 enters between the two side grounding elastic paws 11 from the trumpet mouth), so that the side grounding elastic paw 11 can better right the cable 41.

[0071] At this time, the two side grounding elastic claws 11 and the lower contact structure 51 can clamp the cable shielding layer 411, so the upper contact structure can be omitted. Meanwhile, the lower contact structure 51 can be a lower grounding elastic claw, and the pressing piece 2 is fixedly connected to the lower shielding sheet 5.

[0072] Similarly, when the lower shielding sheet 5 includes two side grounding elastic claws 11, the two side grounding elastic claws 11 and the upper contact structure can clamp the cable shielding layer 411, so the lower contact structure can be omitted. Meanwhile, the upper contact structure can be an upper grounding elastic claw 12, and the pressing piece 2 is fixedly connected to the upper shielding sheet 1.

[0073] In other specific embodiments, the left-right spacing between the two side grounding elastic claws 11 can always be equal. At this time, if the inclination angle of the cable 41 is too large, the cable 41 needs to be preliminarily straightened first, and then the shielding sheet is installed.

[0074] The specific embodiment 2 of the cable connector provided by the utility model is as follows:

[0075] The purpose of the embodiment is to provide a cable connector that does not include a pressing piece.

[0076] On the basis of referring to Figures 1-10 , as shown in Figure 11 , the difference between the embodiment and the specific embodiment 1 is that the specific embodiment 1 includes the pressing piece 2, and the contact structure corresponding to the shielding sheet connected with the pressing piece 2 is a grounding elastic claw; and in the embodiment, since there is no pressing piece 2, the upper and lower contact structures can all be grounding elastic claws, grounding convexes or grounding buckles.

[0077] In other specific embodiments, when the left and right grounding elastic claws are in the shape of an outer "8", the left and right grounding elastic claws and the lower (upper) contact structure cooperate to clamp the cable, so the upper (lower) contact structure does not need to be provided.

[0078] The specific embodiment 3 of the cable connector provided by the utility model is as follows:

[0079] The purpose of the embodiment is to provide a cable connector that includes a conductive adjusting piece.

[0080] On the basis of referring to Figures 1-11 , as shown in Figures 12-16 , the difference between the embodiment and the specific embodiment 1 is that in the specific embodiment 1, the grounding elastic claw is connected to the shielding sheet body, and the pressing piece 2 is used to press the grounding elastic claw; and in the embodiment, the grounding elastic claw is connected to the adjusting piece body, the shielding sheet includes a pressing portion 13 and a grounding perforation 14, and the pressing portion 13 is used to press the grounding elastic claw passing through the grounding perforation 14.

[0081] As shown in Figures 12-16As shown, the cable assembly 300 further comprises a conductive adjusting piece 6, the conductive adjusting piece 6 comprises an adjusting piece body and a grounding spring claw connected on the adjusting piece body, the upper shielding piece 1 or the lower shielding piece 5 comprises a grounding through hole 14 for the grounding spring claw to pass through and a pressing part 13 for pressing the grounding spring claw to make the grounding spring claw deform to the cable shielding layer 411, the grounding spring claw constitutes the upper contact structure or the lower contact structure 51, the pressing part 13 is used for adjusting the deformation degree of the grounding spring claw along with the movement of the conductive adjusting piece 6, the adjusting piece body is used for being fixedly connected with the shielding piece provided with the grounding through hole 14 after the grounding spring claw deforms to cooperate with the corresponding contact structure and clamps the cable shielding layer 411, so that the connection between the grounding spring claw and the shielding piece provided with the grounding through hole 14 is realized. Wherein, the conductive adjusting piece 6 is made of existing conductive materials (for example, copper, aluminum or stainless steel).

[0082] In one specific embodiment, the upper shielding piece 1 comprises the grounding through hole 14, the pressing part 13 is used for pressing the grounding spring claw downward, and the adjusting piece body is fixedly connected on the upper shielding piece 1. Before the adjusting piece body is fixedly connected on the upper shielding piece 1, the grounding spring claw is passed through the grounding through hole 14, and the conductive adjusting piece 6 is moved along the front and back directions, so that the deformation degree of the grounding spring claw is changed, and after the grounding spring claw clamps the cable shielding layer 411 and the lower contact structure 51, the adjusting piece body is fixedly connected on the upper shielding piece 1.

[0083] In another specific embodiment, the lower shielding piece 5 comprises the grounding through hole 14, the pressing part 13 is used for pressing the grounding spring claw upward, and the adjusting piece body is fixedly connected on the lower shielding piece 5.
