Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of connectors, and in particular relates to a transfer bent copper bar contact piece and a connector using the contact piece. Background Art
[0002] In the existing field of high-current connectors, in order to achieve a 90° transition between the connector and the user equipment bus, the method adopted is to vertically connect the jack component and the copper busbar through fasteners. The fasteners are generally screws, and the jack component and the copper busbar are perpendicular to each other. However, when the jack component is used for a long time in an environment with high-intensity vibration, it is not reliable to achieve a conductive connection between the jack component and the copper busbar by tightening the screws. The screws may be loose, causing the copper busbar and the jack component to loosen, resulting in poor contact and affecting the conductivity and stability of signal transmission. If thread glue is applied to the screws to prevent loosening, the thread glue will not have the desired effect due to the heat generated by the high-current connector, and the thread glue will affect the conductivity of the connector. In order not to affect the conductivity of the connector and the stability of signal transmission, the screws used as fasteners cannot be prevented from loosening by applying thread glue.
[0003] The patent with the existing application number CN117728211A discloses a 90° elbow connector, which includes a shell body, a cylindrical terminal, and a copper bus terminal assembly. The shell body is provided with a first jack and a second jack which are perpendicular to each other and connected. The cylindrical terminal is inserted into the shell body along the first jack, and the copper bus terminal assembly is inserted into the shell body along the second jack, so that the cylindrical terminal and the copper bus terminal assembly are perpendicular to each other, and the insertion end of the copper bus terminal assembly intersects and contacts with the insertion end of the cylindrical terminal and is connected by a fastening bolt. The cylindrical terminal and the copper bus terminal assembly in the application are directly fixed and connected by fastening bolts. Although the cylindrical terminal and the copper bus terminal assembly can have a pre-tightening force by fastening bolts, in a long-term vibration environment, the fastening bolts vibrate and gradually come out of the corresponding bolt holes, so that the cylindrical terminal and the copper bus terminal assembly gradually loosen, the reliability is reduced, and the contact resistance is increased, which leads to an increase in the temperature rise of the connector, and under long-term thermal fatigue, the overall performance of the connector is reduced.
[0004] The contact is the core component of the connector. For high-current connectors, the contact (socket component, etc.) has high precision requirements, complex processing technology, and a more difficult processing process than ordinary contacts. Therefore, in order to ensure that the conductivity of high-current connectors in a vibration environment meets the requirements, it is necessary to improve the high-current connector, but the cost of improving the contact is high. In order to meet the needs of high-current connectors, as well as considerations such as the difficulty of processing, processing accuracy, and processing costs, this patent utility model provides a transfer-type bent copper busbar contact for high-current connectors, which effectively solves the problem of loose contact in complex environments such as high-intensity vibration, and ensures conductivity and reliable signal transmission.

[0047] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0048] Embodiment 1 of the utility model of a transfer bent copper busbar contact piece, as shown in Figures 1 to 6 As shown, the contact piece comprises a copper bar 1, a riveting screw 2, and a socket component 3. The socket component 3 has an insertion end as a front end and the other end as a rear end.
[0049] The end of the copper bar 1 that cooperates with the socket component 3 is provided with a vertically extending boss 102, and the boss 102 can extend to both sides of the copper bar 1 or to one side. A stepped hole 101 is provided on one end face of the boss 102, and a stepped shaft 301 is provided at the rear end of the socket component 3. The stepped shaft 301 is forcibly installed in the stepped hole 101 to achieve the positioning and preliminary fixation of the copper bar 1 and the socket component 3. In this embodiment, the stepped hole 101 includes a large hole near the end face of the boss and a small hole at the bottom, and the stepped shaft 301 includes a large shaft and a small shaft arranged in sequence from front to back. The small shaft of the stepped shaft 301 passes through the large hole of the stepped hole 101 and is forcibly fixed to the small hole at the bottom of the stepped hole 101. The large shaft of the stepped shaft 301 is in clearance with the large hole of the stepped hole 101, so that after the stepped shaft 301 passes through the large hole of the stepped hole 101, the small shaft of the stepped shaft 301 is forcibly fixed to the small hole of the stepped hole 301.
[0050] The other end surface of the boss 102 is provided with a tapered hole 103 for the rivet screw 2 to pass through and matching with the head of the rivet screw 2. The tapered hole 103 is connected with the stepped hole 101. In this embodiment, the rivet screw 2 is a countersunk rivet screw, so the hole on the copper busbar 1 is a tapered hole 103 matching with the countersunk rivet screw. In other embodiments, the shape of the through hole on the copper busbar can be determined according to the shape of the head of the rivet screw.
[0051] The rear end face of the stepped shaft 301 is provided with a screw hole that axially penetrates the stepped shaft 301 and communicates with the insertion cavity 303 of the socket component 3. The rivet screw 2 penetrates the tapered hole 103 and matches with the screw hole to achieve the connection and fixation between the copper bar 1 and the socket component 3. After the rivet screw 2 is screwed into the screw hole, the head of the rivet screw is lower than the outer surface of the copper bar or is flush with the outer surface of the copper bar, so that the copper bar can fit with the busbar of the user equipment.
[0052] The riveting screw 2 includes a threaded shaft 201 near the head of the riveting screw 2 and a riveting shaft 202 at the tail of the riveting screw 2. The tail end surface of the riveting shaft 202 is provided with an axially extending inner hole 203, and the inner hole 203 is used for riveting operation to further fix the riveting screw 2 and the socket component 3.
[0053] The screw hole includes a threaded hole 304, a light hole 305, and a horn hole 306 which are arranged in sequence from back to front. The threaded hole 304 is threadedly connected to the threaded shaft 201, and the light hole 305 is clearance-matched with the riveting shaft 202. The horn hole 306 is connected to the insertion cavity 303, and the diameter of the horn hole 306 gradually increases from back to front, so that the inner wall of the horn hole 306 forms a riveting inclined surface 302.
[0054] After the rivet screw 2 is screwed into the screw hole, the head of the rivet screw 2 cooperates with the tapered hole 103 of the copper busbar 1, and the head of the rivet screw prevents the copper busbar 1 from moving backward by cooperating with the tapered hole 103. The threaded shaft 201 is threadedly connected with the threaded hole 304, the rivet shaft 202 cooperates with the light hole 202, and the end of the rivet shaft 202 is located in the horn hole 306, that is, the outer wall of the inner hole 203 is in the horn hole 306. At this time, the copper busbar 1 is threadedly connected with the socket component 3 through the rivet screw 2.
[0055] Use a special riveting tool to pass through the insertion cavity 303 from the insertion end of the socket component 3 and extend into the inner hole 203, and then rivet the inner hole 203. At this time, the inner hole 203 and the outer wall of the inner hole serve as a riveting structure matched with the special riveting tool. Under the action of the special riveting tool, the outer wall of the inner hole 203 expands outward and fits with the riveting bevel 302, and the outer wall of the inner hole undergoes irreversible deformation. The riveting bevel 302 axially stops the outer wall of the inner hole 203, thereby limiting the rivet screw 2 in the screw hole of the socket component 3 to prevent the rivet screw 2 from coming out of the screw hole. The head of the rivet screw 2 cooperates with the tapered hole 103 of the copper bar 1, and the riveted inner hole 203 cooperates with the horn hole 306, so as to limit and fix the copper bar 1 and the socket component 3 in the axial direction to prevent the copper bar 1 and the socket component 3 from loosening under a vibration environment.
[0056] A wire spring hole 308 is provided on the inner wall of the plug-in cavity of the jack component. The wire spring hole 308 has low and stable contact resistance, small plug-in force, low contact wear, long plug-in life, and can maintain high reliability of electrical contact in a strong vibration and impact environment.
[0057] In summary, the riveting screw 2 has a head that matches the copper busbar 1 and a threaded shaft 201 that is threadedly connected to the threaded hole 304 of the socket component 3. The tail end of the riveting screw 2 is provided with a riveting shaft 202, and the riveting shaft 202 is provided with an axially extending inner hole 203 to facilitate the riveting operation, and on the basis of thread fixation, the riveting screw 2 and the socket component 3 are further fixed; correspondingly, the socket component is provided with a riveting bevel 302, which is used to axially stop the riveted part of the riveting shaft 202 after the riveting shaft 202 is riveted, so as to completely avoid the loosening or separation of the socket component 3 and the copper busbar 1.
[0058] When the contact is used for a long time in an extreme environment such as high-intensity vibration, it is not reliable to force the copper busbar 1 and the socket component 3 and tighten the screws. During the vibration process, the forced installation will loosen, and the interference fit will be transformed into a clearance fit. During the vibration process, the screw will rotate relative to the threaded hole, or the thread will fail, causing axial movement between the screw and the threaded hole, thereby loosening the copper busbar 1 and the socket component 3. In the case of not affecting the conductivity or stable signal transmission, thread glue cannot be applied to the screws used to fix the copper busbar 1 and the socket component 3 to prevent loosening. Therefore, the utility model designs a special countersunk rivet screw to tighten and fix the copper busbar 1 and the socket component 3, and then inserts a special riveting tool from the insertion end of the socket component to rivet, so that the rivet screw 2 and the socket component 3 are axially limited, and after riveting, the rivet screw can also be prevented from rotating relative to the socket component, thereby achieving further fixation, preventing the rivet screw 2 from axially moving and falling out of the screw hole, and further preventing the copper busbar 1 and the socket component 3 from loosening, forming a new adapter socket structure, ensuring the conductivity and stable signal transmission between the copper busbar and the socket component.
[0059] The utility model is a second embodiment of a transfer bent copper busbar contact piece, as shown in FIG. Figures 7 to 11 As shown, the second embodiment is improved on the basis of the first embodiment. The riveting shaft 202 of the riveting screw 2 is provided with an axially extending sheet structure 204, and correspondingly, the inner wall of the horn hole 306 (i.e., the riveting inclined surface 302) is also provided with a groove 307. When riveting, the riveting shaft is riveted on the riveting inclined surface 302, and the sheet structure 204 is embedded in the deeper groove 307, that is, the bending deformation degree of the sheet structure is higher, and the groove 307 limits the circumferential position of the sheet structure 204, thereby preventing the riveting screw 2 and the screw hole from rotating relative to each other.
[0060] In this embodiment, a notch 205 is provided on the outer wall of the inner hole 203, and the sheet structure 204 is arranged in the notch 205 and extends axially in the notch 205; that is, the sheet structure and the riveting shaft are integrally formed, and a sheet structure can be formed by processing two spaced split grooves on the end face of the riveting shaft axially backward. According to the different specifications of the riveting screw 2, different numbers of sheet structures 204 and notches 205 are provided, and the sheet structures 204 are circumferentially distributed around the inner hole and arranged in the notch 205. Correspondingly, the inner wall of the horn hole 306 is increased with the same number of grooves 307; in addition, the grooves 307 can extend from the horn hole 306 to the inner wall of the light hole 305, that is, one groove 307 can be opened on the inner wall of the light hole and the horn hole at the same time.
[0061] Furthermore, the width of the groove 307 in the circumferential direction is greater than the width of the sheet structure 204. When the riveting screw is screwed in, the center of the sheet structure 204 may not be aligned with the center of the groove 307 due to a certain error in the screwing angle. Since the width of the groove 307 is greater than the width of the sheet structure 204, the sheet structure 204 can still be embedded in the groove 307 during riveting, thereby reducing the difficulty of riveting and improving the efficiency of riveting. Furthermore, in another embodiment, a plurality of grooves 307 are distributed in the circumferential direction, and the sheet structure has only one groove, which can also improve the success rate of aligning the sheet structure with the groove and improve the assembly efficiency.
[0062] When the riveting screw 2 is riveted by a special riveting tool, the sheet structure 204 is riveted into the corresponding groove 307. The groove 307 limits the sheet structure 204, so that the riveting screw 2 can be radially stopped from rotating, thereby preventing the riveting screw 2 from rotating in a high-intensity vibration environment, thereby preventing the copper bus 1 and the socket component 3 from loosening.
[0063] Since the width of the groove 307 should be greater than the width of the corresponding sheet structure 204, when the rivet screw 2 is screwed into the threaded hole, if the sheet structure 204 is not strictly aligned with the groove 307, the sheet structure 204 can still be embedded in the groove 307 during riveting. When vibration occurs and the rivet screw rotates, although the width of the groove 307 is greater than the width of the sheet structure 204, the rivet screw 2 is only allowed to rotate through a small angle, and the side wall of the groove can stop the sheet structure to limit the rivet screw from rotating further. After the rivet screw rotates through a small angle, it can only move axially a small distance relative to the threaded hole of the socket component, and this small distance will not cause the copper bus 1 to loosen and separate from the socket component 3, affecting the conductive performance.
[0064] After the riveting operation, the riveting shaft 202 of the riveting screw 2 is turned outward, and the riveting bevel 302 of the screw hole of the socket component axially stops the riveted part of the riveting shaft 202. At the same time, the sheet structure 204 is turned outward into the groove 307, which can prevent the riveting screw 2 from rotating, and at the same time realize the riveting screw 2 to stop retreating and stopping rotation, and firmly limit the riveting screw 2 in the screw hole of the socket component 3, thereby realizing the firm combination of the copper bus 1 and the socket component 3.
[0065] In other embodiments of a transition bent copper busbar contact of the utility model, in addition to forcibly positioning the contact body and the copper busbar through the hole axis, other structures can also be used. For example, the contact body and the copper busbar can be prevented from rotation and initially fixed through a keyway structure. A convex key or a groove is provided on the contact body, and a groove or a convex key is correspondingly provided on the copper busbar. The convex key is forcibly installed in the groove to achieve positioning and initial fixation of the contact body and the copper busbar.
[0066] The utility model provides an embodiment of a connector using the above-mentioned transfer bent copper bar contact piece, as shown in Figure 12 to Figure 14 As shown, in this embodiment, two contacts 4 (i.e., transfer bent copper bus contacts) are provided, the socket components of the two contacts 4 are inserted into the housing 5, and the copper bus surfaces of the two contacts away from the housing 5 are in contact with the plane of the device bus. Each copper bus is provided with two through holes, which are connected and fixed to the threaded holes on the bus by screws to realize the transmission function of high-power signals.
[0067] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
