Description

Technical Field

[0001] This utility model mainly relates to the field of electronic component connection technology, specifically an improvement in the structure of a connecting piece. Background Technology

[0002] In the current field of electronic component interconnection technology, connectors serve as a crucial bridge connecting chips and cables. Their structural design and manufacturing process directly affect the overall performance, signal transmission stability, and service life of electronic devices.

[0003] Although some improvements have been made in existing technologies, such as the sensor skeleton connector disclosed in CN211697846U currently used by our company, which includes a main body with a front end and a rear end, and a cable riveting part near the rear end, and the front end of the main body is flipped downwards to form a front positioning flap, this technology has the advantages of simple positioning, convenient operation, and reliable positioning during skeleton injection molding. However, its bends and folds are prone to significant deformation during stamping. This deformation defect not only deviates from the design tolerance but also prevents the connector from achieving precise docking with the chip and cable, thus impairing the stability and conductivity of the connector, potentially causing signal attenuation or interruption, and reducing the reliability of electronic components. Utility Model Content

[0004] This utility model provides a solution that is significantly different from existing technologies, addressing the problem of overly simplistic solutions in existing technologies. It primarily offers an improved connector structure to solve the deformation problem mentioned in the background section, where the connectors used by our company deform during the stamping process in their bends and folds. This deformation not only causes the connector dimensions to deviate from the original design tolerances but also affects the accurate connection between the connector and chips or cables, thereby weakening connection stability and electrical conductivity. Furthermore, it may cause signal attenuation or transmission interruption, reducing the overall reliability of electronic components.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: An improved connecting piece structure includes a main piece body, one end of which is provided with a transition connecting piece, and a riveting wing is provided on the main piece body near the transition connecting piece.

[0006] The main body includes a front end piece, a bend section, a folding section and a rear end piece connected in sequence, and the front end piece is provided with a first positioning hole.

[0007] More preferably, the outer periphery of the first positioning hole of the front end piece is provided with a protruding structure, and the main piece body is provided with two sets of protrusions.

[0008] More preferably, the rear end piece is folded upward on both sides to form riveted winglets, and the riveted winglets on both sides are arranged symmetrically.

[0009] More preferably, the riveted flap includes a connecting base connected to the rear end flap, the connecting base having two toothed pieces with a gap between them.

[0010] In a further preferred embodiment, the two lateral sides of the rear end piece connected to the riveting wing piece are recessed inward to form a neck, and a notch is formed at the neck. The connecting base of the riveting wing piece extends into the notch, and the folded portion of the connecting base is connected to the side of the notch along the length direction. The two ends of the folded portion of the connecting base are disconnected and misaligned with the opposite side walls of the notch.

[0011] More preferably, the transition connecting piece has a second positioning hole, and one end of the rear end piece is connected to the transition connecting piece.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: This connector reduces deformation by moving the bend to the non-bending position, ensuring stable connection with chips and cables and stable circuit performance. Its dual positioning structure, employing a first positioning hole on the front end and a second positioning hole on the transition connector, improves injection molding positioning accuracy compared to traditional single positioning structures, protecting the mold and increasing production efficiency. Furthermore, the symmetrical riveting winglets and B-shaped double-toothed structure evenly cover the cable, increasing the contact area and improving pull-out force. Simultaneously, the tooth gap buffers the riveting force, preventing core wire damage and ensuring production stability and overall reliability of electronic components.

[0018] Please refer to the appendix carefully. Figures 1-3 An improved connecting piece structure includes a main piece 1, a transition connecting piece 3 at one end of the main piece 1, and a riveting wing piece 2 on the main piece 1 near the transition connecting piece 3.

[0019] The main body 1 includes a front end piece 101, a bend section 103, a fold section 104 and a rear end piece 105 connected in sequence. The front end piece 101 has a first positioning hole 102.

[0020] In this embodiment, as Figure 1 As shown, the outer periphery of the first positioning hole 102 of the front end piece 101 is provided with a protruding structure, and the main piece 1 is provided with two sets.

[0021] With the above structure, the main body 1 adopts a two-set parallel combined design, which, together with the two first positioning holes 102 on the front end piece 101, makes the connecting piece easier to pick up and position during the injection molding process, which can enhance the fitting accuracy between the connecting piece and the mold positioning component and reduce the risk of the connecting piece falling off.

[0022] In this embodiment, as Figure 1 and Figure 2 As shown, the rear end piece 105 is folded upward on both sides to form riveted wing pieces 2, and the riveted wing pieces 2 on both sides are arranged symmetrically.

[0023] With the above structure, the symmetrically designed riveting wing 2 can evenly cover the cable, which can ensure the balanced force distribution during the riveting process, improve the riveting firmness between the cable and the connecting piece, and the symmetrical arrangement can avoid stress concentration on one side and reduce the risk of the cable core being cut during riveting.

[0024] In this embodiment, as Figure 1 and Figure 2As shown, the riveted wing 2 includes a connecting base 201 connected to the rear end piece 105. The connecting base 201 is provided with two toothed pieces 202, and there is a gap between the two toothed pieces 202.

[0025] Through the above-mentioned B-shaped structure design, the two toothed plates 202 can increase the contact area with the cable, improve the pull-out force after riveting, ensure the cable and the connecting plate are firmly connected, and the gap between the toothed plates 202 can play a buffering role during the riveting process, which can prevent the cable core wire from being directly squeezed due to excessive riveting force and prevent the copper wire from being cut.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the two lateral sides of the rear end piece 105 connected to the riveted wing piece 2 are recessed inward to form a neck 106, and a notch 10601 is formed at the neck 106. The connecting base 201 of the riveted wing piece 2 extends into the notch 10601, and the folded part of the connecting base 201 is connected to the side of the notch 10601 along the length direction. The two ends of the folded part of the connecting base 201 are arranged in a discontinuous and staggered manner with the opposite side walls of the notch 10601.

[0027] With the above structure, the connecting base 201 extends into the notch 10601 and connects to the side of the notch 10601 along its length, which can enhance the connection strength between the riveted wing 2 and the rear end piece 105. The staggered arrangement of the two ends of the folded part with the side wall of the notch 10601 can avoid rigid contact between the connecting base 201 and the side wall of the notch 10601, which can reduce stress transmission during the stamping and riveting process and reduce the risk of deformation of the connecting piece.

[0028] In this embodiment, as Figure 1 As shown, a second positioning hole 4 is provided on the transition connecting piece 3, and one end of the rear end piece 105 is connected to the transition connecting piece 3.

[0029] With the above structure, the main body 1, the riveted wing 2 and the transition connecting piece 3 are integrally formed. The second positioning hole 4 can be used to hook the mold positioning post, which can realize the quick and accurate positioning of the connecting piece during injection molding. Moreover, through the cooperation between the positioning hole and the mold, the connecting piece maintains a stable position during the injection molding process.

[0030] The specific operation process of this utility is as follows: First, in the injection molding process, the connecting piece relies on the first positioning hole 102 on the front end piece 101 and the second positioning hole 4 on the transition connecting piece 3 to form a double positioning. The first positioning hole 102 is adapted to the mold positioning component, and the second positioning hole 4 hooks the mold positioning post. The double positioning function realizes the rapid and accurate positioning of the connecting piece in the mold cavity.

[0031] After injection molding is completed, the connecting piece enters the cable riveting process. At this time, the symmetrical riveting wing 2 formed by the upward folding of the two sides of the rear end piece 105 begins to play its role. The symmetrically arranged riveting wing 2 can evenly cover the cable, which can avoid stress concentration on one side. Moreover, the double toothed piece 202 of the B-shaped structure of the riveting wing 2 can increase the contact area with the cable, which can improve the pull-out force after riveting and ensure the cable connection is stable. The gap between the toothed pieces 202 can buffer the force during the riveting process and prevent the riveting force from being too large and cutting the cable core.

[0032] Meanwhile, the necking 106 and notch 10601 at the connection between the rear end piece 105 and the riveting wing piece 2 allow the connecting base 201 to be embedded in the notch 10601 and connected to the side, which can enhance the connection strength between the riveting wing piece 2 and the rear end piece 105. The folded part of the connecting base 201 and the discontinuous staggered arrangement of the side wall of the notch 10601 can avoid stress transmission caused by rigid contact and reduce structural deformation during stamping and riveting, thereby achieving a stable connection between the connecting piece and the sensor cable and the chip, and meeting the reliability requirements for long-term use of the sensor.

[0033] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
