Description

Technical Field

[0001] The invention relates to the technical field of high-frequency conductive connection, in particular to a male terminal connection module. Background Art

[0002] As communication equipment develops towards miniaturization, high density and high speed, high-speed cable connectors are increasingly used. Figure 1 The structure of an existing high-speed cable connection assembly is shown, that is, a schematic diagram of the structure of a male-end cable connector and a female-end cable connector 2 in a plugged-in state formed by a plurality of male-end connection modules 1. Figure 2-6 The figure shows the structures of the male end connection module 1 in the high-speed cable connection assembly. Figure 2-6 It can be seen that the existing male end connection module 1 mainly includes a high-speed cable part 10, a terminal module 13, an insulating sleeve 14 and a shielding cylinder. The terminal module 13 includes an insulating component 130 and a male end contact piece injection-molded in the insulating component 130. The two ends of the male end contact piece extend from the two ends of the insulating component 130 respectively, and one end is a wiring terminal and the other end is a plug-in end 131. The wire core of the high-speed cable part 10 is connected to the wiring terminal on the terminal module 13. The insulating sleeve 14 includes a hollow rectangular body, one end of the body is used for the female end contact piece to extend into the plug-in port, and the other end has a clamping arm extending from both sides of the width direction to clamp with the two sides of the width direction of the insulating component 130. After the insulating sleeve 14 is clamped on the front side of the insulating component 130, the contact piece extends into the insulating sleeve 14. The shielding cylinder is wrapped around the terminal module and the outside of the insulating sleeve as a whole, which plays a role in shielding the plug-in position.

[0003] Combination Figure 2-7 It can be seen that the shielding tube of the existing male terminal connection module is a split structure, including a U-shaped bottom shell part 12 and a flat cover part 11 fixedly buckled at the bottom shell opening, and the two parts are buckled to wrap the terminal module 13 and the insulating sleeve 14. The insulating component of the terminal module 13 is connected with the two clamping arms of the insulating sleeve 14, and the two side surfaces in the thickness direction of the insulating sleeve 14 are respectively provided with limiting protrusions 140, and the two side surfaces in the thickness direction of the shielding tube are respectively provided with limiting protrusions 124 for matching with the corresponding side surfaces of the insulating component 130 and limiting holes 110 for matching with the limiting protrusions 140. Moreover, the two side surfaces in the thickness direction of the insulating sleeve 14 and the shielding tube are respectively provided with sleeve avoidance holes 141 and shielding tube avoidance holes 111 for avoiding elastic deformation of the male contact in the plugged state. When the male-end connection module 1 is plugged into the female-end cable connector 2 , the female-end contact of the female-end cable connector 2 extends from the plug-in port into the insulating sleeve 14 and is plugged and connected with the male-end contact of the male-end cable contact module 1 .

[0004] Although the above-mentioned existing male end connection module has a high degree of integration, a small volume, and realizes full shielding of the plug-in position through the shielding tube, since the insulating sleeve 14 is clamped with the two side edges of the insulating component through the clamping arm, there is an air gap between the clamping arm and the insulating component. Here, the insulating material of the insulating component, the air gap and the insulating material of the clamping arm exist on both sides of the male end contact in the width direction, and the dielectric environment is relatively complex. This makes it easy to generate resonance at the position of the shielding tube, which is not conducive to high-speed transmission of signals. Summary of the invention

[0005] The object of the present invention is to provide a male terminal connection module to solve the problem that the male terminal connection module in the prior art is prone to resonance due to the complex medium environment around the male terminal contact at the shielding tube, which is not conducive to high-speed signal transmission.

[0006] The male end connection module of the present invention comprises a terminal module, an insulating sleeve and a shielding sleeve. The insulating sleeve and the terminal module are arranged in parallel and independently in the plugging direction. The rear end face of the insulating sleeve (14) is located in front of the front end face of the terminal module (13). The insulating component of the terminal module is fixedly connected to the wall of the shielding sleeve. The insulating sleeve is fixedly connected to the wall of the shielding sleeve.

[0007] Furthermore, a fixing protrusion punched inward is provided on the side wall of the bottom shell portion of the shielding tube, and the insulating component and / or the insulating sleeve is fixed by being snap-fitted to the fixing protrusion via the corresponding side wall.

[0008] Furthermore, a fixing groove cooperating with the fixing protrusion is provided on the side surface of the insulating component and / or the insulating sleeve corresponding to the side wall of the bottom shell part, so that the fixing protrusion can be inserted into the fixing groove.

[0009] Furthermore, the insulating sleeve is a rectangular block structure, which has an escape channel for the plug-in end of the male contact piece to pass through and extend out.

[0010] Furthermore, the insulating sleeve is a rectangular block structure, which has an inner cavity for male and female contacts to extend from both sides and be plugged in and connected. The two side surfaces in the thickness direction of the insulating sleeve are respectively provided with sleeve avoidance holes for avoiding elastic deformation of the male contacts in the plugged state.

[0011] Furthermore, two side surfaces of the insulating component in the width direction are straight side surfaces, and the fixing grooves are provided on the straight side surfaces.

[0012] Furthermore, a concave-convex limiting structure for concave-convex cooperation with corresponding side surfaces of the insulating component and / or the insulating sleeve is provided on the cylinder wall in the thickness direction of the shielding cylinder.

[0013] Furthermore, the concave-convex limiting structure is a limiting protrusion formed by inward stamping.

[0014] Furthermore, the avoidance structure provided on the wall of the shielding cylinder corresponding to the plug-in end of the male contact piece and allowing the male contact piece to elastically deform in the plug-in state is an avoidance groove.

[0015] Furthermore, the avoidance groove is a stamping groove formed by stamping a thinning structure on the cylinder wall.

[0016] The male end connection module of the present invention improves the existing male end connection module by changing the structure of the insulating sleeve and the fixing method between the insulating sleeve and the shielding tube, so that the insulating component of the terminal module and the insulating component are two independent and parallel insulating structures in the plug-in direction. This makes it easier to make the insulating component and the insulating sleeve have a regular shape, which helps to optimize and unify the dielectric environment of the signal loop on the outside of the terminal module and the outside of the insulating sleeve, thereby avoiding the generation of resonance and improving the signal transmission rate.

DETAILED DESCRIPTION

[0019] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0020] The male end connection module of the present invention is mainly aimed at the male end connection module of the prior art, in which the insulating component of the terminal module and the insulating sleeve are connected by the two side clamping arms extending from the end of the insulating sleeve and the two sides of the insulating component in the width direction, which causes the dielectric environment of the signal loop outside the terminal module to be complex, easily resonates, and affects the high-speed transmission. The present invention improves the structure of the insulating sleeve and its fixing method in the shielding tube, so that two independent components arranged in parallel in the plug-in direction are formed between the insulating sleeve and the insulating component of the terminal module, that is, the rear end face of the insulating sleeve is on the front side of the front end face of the terminal module, so that their shapes can be easily set, which helps to optimize and unify the dielectric environment of the signal loop outside the terminal module and the insulating sleeve, and improve the transmission rate. Of course, when the terminal module and the insulating sleeve are set separately, they are fixedly connected to the shielding tube respectively to achieve fixed assembly.

[0021] Based on the above concept, the present invention provides the following different preferred embodiments for illustration.

[0022] like Figure 8-12 In the embodiment shown, a specific method of fixedly connecting the insulating component 130 and the insulating sleeve 14 to the shielding tube is specifically provided. This connection method can also optimize the dielectric environment outside the signal loop at the terminal module 13 and the insulating sleeve 14, thereby eliminating resonance. Fig.10As shown, the shielding tube includes a bottom shell part 12 with a U-shaped cross section and a cover part 11 fixedly buckled at the opening of the bottom shell part 12. The two side walls of the bottom shell part 12 are respectively provided with fixing convexities formed by inward stamping. The insulating component 130 and the insulating sleeve 14 of the terminal module 13 are fixedly assembled by forcibly snapping the corresponding side walls with the fixing convexities. In this way, the two side walls of the bottom shell part 12 are still complete side walls as a whole, and the sides of the insulating component 130 and the insulating sleeve 14 can also be regular straight sides. In this way, the dielectric environment of the signal loop on both sides of the width direction of the male end connection module 1 is relatively simple and can be kept as consistent as possible, which helps to eliminate resonance. Of course, in some equally practicable methods, one of the insulating component 130 and the insulating sleeve 14 is bonded and fixed to the bottom shell part 12, and the other is fixed to the bottom shell part 12 by the above-mentioned forcible snap connection, or both are bonded and fixed to the bottom shell part 12.

[0023] In the above-mentioned embodiment, the main function of the fixing convex is to be strongly mounted between the insulating component 130 or the insulating sleeve 14, so as to keep the insulating material components fixed in the bottom shell part 12. The fixing convex can be a bulge or a convex point formed by stamping. Fig.10 In one embodiment shown, the fixing protrusion is a piercing structure 123, so that when the insulating material component is installed from the opening of the bottom shell part 12, it can be more reliably fixed therein.

[0024] Based on the above embodiment, in a more preferred embodiment, Fig. 9 and 12 As shown, when the insulating material components such as the insulating part 130 or the insulating sleeve 14 are forcibly engaged with the fixing protrusions, in order to facilitate a more accurate installation position of the insulating material components in the bottom shell part 12, a fixing groove 143 is provided on the side of at least one of the insulating part 130 and the insulating sleeve 14, and the fixing protrusion is inserted into the fixing groove 143, so that the position of the insulating material component in the bottom shell part 12 in the plug-in direction can be determined by the cooperation of the two.

[0025] Based on the above embodiment, in a more preferred embodiment, Figure 10-11As shown, the bottom shell part 12 and the cover plate part 11 are respectively provided with limiting protrusions 124 on the opposite wall surfaces, and the limiting protrusions 124 are formed by inwardly stamping the corresponding wall surfaces. The insulating component 130 and the insulating sleeve 14 are respectively provided with corresponding limiting recesses 142. Through the concave-convex cooperation of the limiting protrusions 124 and the limiting recesses 142, the assembly reliability between the insulating component 130 and the insulating sleeve 14 and the shielding tube can be further enhanced. The insulating material components are evenly clamped on the four sides of the shielding tube, and even when the high-speed cable part 10 is subjected to pulling force, it can be well kept in the shielding tube. Moreover, in this way, when the fixed assembly between the shielding tube and the insulating material component is realized, the circumferential structure of the shielding tube is complete, and no holes are required, which ensures the shielding effect while making the dielectric environment outside the signal loop better. Of course, in some modified embodiments, any one of the insulating component 130 and the insulating sleeve 14 may be matched with the tube wall in the thickness direction of the shielding tube through the limiting protrusion 124 and the limiting recess 142, or the stamped limiting protrusion 124 may be formed by a limiting spring arm by stamping and cutting, all of which fall within the protection scope of the present invention.

[0026] Based on the above embodiments, the following two embodiments provide specific examples of the structure of the insulating sleeve 14. Figure 12-13 ,exist Fig.12 In one embodiment shown, the combination Fig. 9 The insulating sleeve 14 is a rectangular block structure, and the inside of the rectangular block structure has a through avoidance channel 145 for the plug-in end 131 of the male contact to pass through and extend. The two end faces of the insulating sleeve 14 in the plug-in direction of this structure are both planes, and the two side faces in the width direction and the two side faces in the thickness direction are relatively regular as a whole, except for the locally arranged fixing grooves 143 and the limiting recesses 142. Correspondingly, the wall surface of the shielding tube that matches it is also relatively regular as a whole, so that the dielectric environment outside the signal loop can be better guaranteed.

[0027] exist Fig.13 In one embodiment shown, the insulating sleeve 14 is a rectangular block structure. Fig.12 As for the structure shown, it is longer and has an inner plug-in cavity that runs through in the plug-in direction and allows the male contact and the female contact to extend from both sides and be plugged in and connected. The two side surfaces of the insulating sleeve 14 in the thickness direction are respectively provided with sleeve avoidance holes 141 for avoiding elastic deformation of the male contact in the plug-in state.

[0028] Based on the above embodiments, in a better embodiment, Figure 10-11As shown, an avoidance structure for elastic deformation in the plugged-in state is arranged at a position on the wall of the shielding cylinder corresponding to the plug-in end 131 of the male contact piece, and is a avoidance groove 117. The avoidance groove 117 is a stamped groove formed by punching a thinning structure on the corresponding cylinder wall, which is different from the shielding cylinder avoidance hole 111 that passes through the wall of the shielding cylinder in the prior art. This method reduces the number of openings on the shielding cylinder, thereby improving the signal transmission environment while ensuring better shielding, and helping to increase the transmission rate.

[0029] The male connector of the present invention changes the structure of the insulating sleeve and the way it is fixed to the shielding tube so that the male connector and the insulating component of the terminal module are two independent insulating structures arranged in parallel in the plug-in direction. This makes it easier to make the insulating component and the insulating sleeve have a regular shape, which helps to optimize and unify the dielectric environment of the signal circuit on the outside of the terminal module and the outside of the insulating sleeve, thereby avoiding the generation of resonance. Moreover, the insulating sleeve and the insulating component of the terminal module are arranged independently, which can better control the processing size and assembly accuracy of the insulating sleeve. When the male connector and the female connector are plugged in, the air cavity gap between the contact pieces can be controlled within 0.05mm, thereby improving the signal transmission rate.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the contents of the description and drawings of the present invention should also be included in the protection scope of the present invention.
