Description

Technical Field

[0001] This utility model relates to the field of electrical connectors, and in particular to a connecting terminal block. Background Technology

[0002] Metal terminals are an important component of electrical connectors. Made of highly conductive materials (such as copper or copper alloys), they ensure stable and efficient connections between circuits through their excellent conductivity. In electrical connectors, metal terminals are responsible for transmitting power and signals from one point to another, making them a key component for achieving electrical connections and signal transmission between electronic devices.

[0003] Using strip material is the conventional method for manufacturing metal terminals. A sheet of highly conductive material is prepared in advance, and the metal terminal is formed by stamping or other methods, corresponding to the shape of the metal terminal. Excess strip material is then removed to form a complete terminal. Some existing bent terminals, due to the influence of the strip material and the structure and layout of the metal terminal, are usually bent after the metal terminal has been separated from the strip material. This requires a significant time interval between stamping and bending, resulting in low efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a continuous terminal block to solve the problem of low production efficiency of bent terminals.

[0005] To solve the above-mentioned technical problems, the present invention provides a connecting terminal block comprising multiple metal terminals and a connecting strip connected to each of the multiple metal terminals. Each of the multiple metal terminals comprises an insertion section, a shoulder, and a bending section distributed sequentially along its length. The lateral width of the shoulder is greater than the lateral width of the bending section. The connecting strip includes a connecting portion corresponding to each metal terminal, and each connecting portion includes two connecting arms. The two connecting arms are connected to the area on the shoulder located outside the two sides of the bending section.

[0006] Furthermore, the bending section is formed by stamping process. The stamping of the bending section forms a material ejection hole at the position of the connecting strip corresponding to the bending section, and forms the two connecting arms on the area on both sides of the material ejection hole on the connecting strip.

[0007] Furthermore, the bending segment includes a horizontally extending segment distributed along the axial direction away from the insertion segment, a first bending segment formed by bending the horizontally extending segment, and a second bending segment formed by bending the first bending segment; the bending segment, the shoulder, and the insertion segment are coaxially distributed such that the shoulder has an area exposed beyond the lateral sides of the bending segment.

[0008] Furthermore, the width of the portion of the horizontal extension section and the first bending section near the horizontal extension section is wider, while the width of the first bending section away from the horizontal extension section and the second bending section is narrower; the material ejection hole forms a first hole segment corresponding to the wider portion of the bending section and a second hole segment corresponding to the narrower portion of the bending section, with the width of the first hole segment being wider than that of the second hole segment, so that the two connecting arms include a first arm segment disposed on both sides of the first hole segment and a second arm segment disposed on both sides of the second hole segment, and the ends and shoulders of the two first arm segments away from the insertion section are integrally connected by a break portion.

[0009] Furthermore, the broken portion has a first tapered section connected to the end of the first arm segment and a second tapered section connected to the shoulder on the side away from the insertion segment, the first tapered section and the second tapered section being thinned towards each other and integrally connected.

[0010] Furthermore, on both opposite sides of the first and second gradually narrowing sections, there are inclined fracture surfaces that gradually thin out, and the fracture surfaces form V-shaped easy-break grooves on both sides of the first and second gradually narrowing sections.

[0011] Furthermore, the width of the first hole segment is greater than the width of the wider portion of the bent segment.

[0012] Furthermore, each of the two first arm segments has an inwardly inclined end at the end furthest from the second arm segment, and the first tapering segment is formed at the end of the inclined end.

[0013] Furthermore, a gap groove is formed between each pair of adjacent connecting parts; the connecting strip also includes a connecting edge strip connected to the end of each connecting part away from the metal terminal.

[0014] Furthermore, the connecting strip is provided with through holes at positions corresponding to each interval slot along the axial direction to facilitate breaking the connecting part.

[0015] Furthermore, a tight fitting portion is provided on both sides of the insertion section.

[0016] The connecting terminal block of this utility model has at least the following beneficial effects: by setting a shoulder between the insertion section and the bending section, and setting a connecting part on the connecting strip, the connecting part cooperates with the shoulder to connect the metal terminal to the connecting strip while the bending section is separated from the connecting strip, thereby reserving bending space so that the bending section can be bent and formed at the same time as stamping the metal terminal, thereby greatly shortening the processing time, reducing processing steps, and saving the processing cost of metal terminals to a certain extent.

Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] Please refer to Figures 1 to 5 The connector terminal block of this utility model includes multiple metal terminals 1 and a connecting strip 2 connected to the multiple metal terminals 1. The metal terminals 1 are used to form a connector with plastic for electrical transmission. The connecting strip 2 is the raw material for the production of the metal terminals 1 and is used for the molding and processing of the metal terminals 1.

[0027] In this embodiment, the metal terminal 1 is made of a conductive metal such as copper. Each metal terminal 1 includes an insertion segment 11, a shoulder 12, and a bent segment 13 arranged sequentially along its length. The length direction of the insertion segment 11 is defined as the axial direction of the metal terminal 1. The insertion segments 11 are evenly distributed along the axial direction, and each insertion segment 11 has a pointed tip at the end away from the shoulder 12. The formation of the pointed tip facilitates the insertion segment 11 to be inserted into the complementary terminal and the corresponding plastic. The tip of the insertion segment 11 is mainly used to mate with the complementary terminal. The insertion segment 11 has a fastening portion 111 protruding on both sides of the end near the shoulder 12 and along a transverse direction perpendicular to the axis. Each side of the fastening portion 111 of the insertion segment 11 has at least two protrusions, each protruding in the middle, so that when the insertion segment 11 is inserted into the plastic, the protrusions can press against the inner wall of the plastic. At least two protrusions can ensure the stability of the insertion segment 11 and make it fit in a balanced and stable manner with the plastic.

[0028] In this embodiment, the shoulder 12 is integrally connected to the end of the insertion section 11 away from the tip, and the shoulder 12 protrudes laterally from both sides of the insertion section 11 and the bending section 13 along the lateral direction (i.e., the width direction of the insertion section 11), so that the lateral width of the shoulder 12 is greater than the lateral width of the insertion section 11 and the bending section 13. The connecting part 22 is connected to the part of the shoulder 12 that protrudes from the bending section 13 and the insertion section 11, so that the connecting part 22 and the bending section 13 are spaced apart, thereby facilitating the bending section 13 to be stamped and bent during the stamping of the metal terminal 1. At the same time, the shoulder 12 can also limit the insertion depth when the insertion section 11 is inserted into the plastic.

[0029] In this embodiment, the bent segment 13 is formed by stamping. Stamping is performed on the connecting strip 2 at a position corresponding to the bent segment 13, and the stamped bent segment 13 is bent using a die. A ejector hole 21 is formed at the position corresponding to the bent segment 13 after stamping, thus forming the bent segment 13. In this embodiment, the bent segment 13 includes a horizontally extending segment 131 distributed along the axial direction away from the insertion segment 11, a first bent segment 132 formed by bending the horizontally extending segment 131, and a second bent segment 133 formed by bending the first bent segment 132. The first bent segment 132 extends perpendicular to the transverse and axial directions of the insertion segment 11, while the second bent segment 133 extends along the axial direction away from the insertion segment 11. The shoulder 12, the insertion section 11, and the horizontal extension 131 of the bending section 13 are coaxially distributed and located on the same axis, so that the shoulder 12 has an area exposed beyond the lateral sides of the horizontal extension 131 of the bending section 13. The portion of the first bending section 132 near the horizontal extension 131 and the horizontal extension 131 are of equal width and relatively wider than the width of the second bending section 133. The portion of the first bending section 132 away from the horizontal extension 131 and the second bending section 133 are of equal width and relatively narrower than the width of the horizontal extension 131. Thus, the width of the second bending section 133 and the width of the portion of the first bending section 132 away from the horizontal extension 131 are both smaller than the width of the horizontal extension 131. The second bending section 133 is used for soldering with the circuit board, and is therefore narrower than the horizontal extension 131. The portion of the horizontal extension 131 that is wider than the second bending section 133 facilitates its fit with plastic to support the second bending section 133.

[0030] In this embodiment, the connecting strip 2 is made of the same material as the metal terminal 1, and the metal terminal 1 is formed by stamping the connecting strip 2. The connecting strip 2 includes a plurality of connecting parts 22 corresponding to each metal terminal 1 and a connecting edge strip 23 connected to one end of each connecting part 22 away from the metal terminal 1. The metal terminal 1 is formed by stamping the connecting parts 22 of the connecting strip 2, and the connecting edge strip 23 is used to connect the connecting parts 22 together.

[0031] In this embodiment, each connecting section 22 includes two connecting arms 221. One end of each connecting arm 221 is integrally connected to the connecting strip 23, and the other end of each connecting arm 221 is integrally connected to the area on the shoulder 12 outside the two sides of the bending section 13. That is, the ends of the two connecting arms 221 away from the connecting strip 23 are respectively connected to the portions of the shoulder 12 that protrude from the bending section 13, so that the bending section 13 is located between the two connecting arms 221 and is independent of each other, so that the bending section 13 can be formed by stamping during the stamping stage without needing to be bent separately after the metal terminal 1 is completed. The two connecting arms 221 are spaced apart, and after the bending section 13 is formed by stamping between the two connecting arms 221, a material ejection hole 21 is formed on the connecting strip 2 between the two connecting arms 221. The bending section 13 is formed by stamping the portion where the ejector hole 21 is located. After the ejector hole 21 is formed by stamping on the connecting strip 2, two connecting arms 221 are formed on both sides of the ejector hole 21. The ejector hole 21 forms a first hole section 211 corresponding to the wider portion of the bending section 13, and a second hole section 212 connecting the first hole section 211 is formed corresponding to the narrower portion of the bending section 13. The width of the first hole section 211 is wider than that of the second hole section 212, so that the two connecting arms 221 include a first arm section 2211 located on both sides of the first hole section 211 and a second arm section 2212 located on both sides of the second hole section 212. To facilitate the formation of the shoulder 12, the width of the first hole section 211 is wider than the width of the horizontal extension section 131, that is, it is wider than the width of the wider part of the bending section 13. The horizontal extension section 131 is located inside the first hole section 211, while the first bending section 132 and the second bending section 133 are both located outside the material ejection hole 21 after bending.

[0032] In this embodiment, the ends of the two first arm segments 2211 are integrally connected to the shoulder 12 on the side away from the insertion segment 11 via a break portion 24. The break portion 24 has a first tapered section 241 connected to the end of the first arm segment 2211 and a second tapered section 242 connected to the shoulder 12 on the side away from the insertion segment 11. The two second tapered sections 242 are formed on two regions of the shoulder 12 that protrude from the horizontal extension segment 131 and are located on the side of the two regions away from the insertion segment 11. Both sides of the first tapering segment 241 and the second tapering segment 242 have inclined, gradually thinning fracture surfaces 243, so that the first tapering segment 241 and the second tapering segment 242 have a frustum-shaped structure. The facing sides of the first tapering segment 241 and the second tapering segment 242 are narrow ends and connected. The fracture surfaces 243 form V-shaped easy-break grooves 244 on both sides of the first tapering segment 241 and the second tapering segment 242, so that the first tapering segment 241 and the second tapering segment 242 are thinned towards each other and integrally connected. The tapering fracture portion 24 and the easy-break grooves 244 allow the metal terminal 1 to bend relative to the easy-break grooves 244 on both sides when needed, so as to break and separate the first tapering segment 241 and the second tapering segment 242. Each of the two first arm segments 2211 has an inwardly inclined end 2213 at the end furthest from the second arm segment 2212, that is, the end of the inclined end 2213 furthest from the second arm segment 2212 is inclined toward the horizontal extension segment 131 to facilitate the stamping forming of the shoulder 12. A first tapering segment 241 is formed at the end of the inclined end 2213 furthest from the second arm segment 2212. Correspondingly, a spacer groove 25 is formed between each pair of adjacent connecting portions 22 to facilitate the formation of multiple independent metal terminals 1 by the stamping process.

[0033] The connecting strip 23 is provided with through holes 231 at the positions of each interval slot 25 along the axial direction to facilitate the breaking of the connecting part 22. The through holes 231 are circular and the interval between two adjacent connecting strips 23 is half a through hole 231, so as to reduce the connection between two adjacent connecting strips 23, making them easy to break while maintaining basic connection.
