Description

Technical Field

[0001] This utility model relates to the technical field of connecting terminals, specifically a false flag-type locking terminal. Background Technology

[0002] Flag terminals are divided into true flag terminals and false flag terminals. Generally, true flag terminals have a hook, while false flag terminals do not. Flag terminals are widely used in many products, including electrical appliances, connectors, transformers, wires, cables, plugs, wire harnesses, lighting fixtures, motors, electronic instruments, etc., so the demand for these products is very large.

[0003] In existing technologies, flag-shaped terminals typically have a terminal block and a female connector on a substrate. The terminal block is used to connect to a wire, while the female connector is used to connect to a male terminal block. Since the terminal block and female connector are connected by only one substrate, the connection strength is weak, and the terminal block and female connector are prone to bending, affecting the terminal's lifespan. For example, patent application number 202420263810.5 discloses a pseudo-flag-shaped locking terminal, which includes a substrate on which a terminal block and a female connector are provided. The substrate has an L-shaped structure, including a horizontal plate and a vertical plate connected together. The terminal block is located on the horizontal plate, and the female connector is located on the vertical plate. A [missing information - likely a design element] is provided at the connection point between the horizontal plate and the vertical plate. The structure is reinforced; this structure strengthens the overall strength of the terminal by adding a reinforcing structure at the connection between the horizontal and vertical plates, preventing accidental bending of the horizontal and vertical plates and extending the service life of the terminal. However, the following problems were found during use: 1. Simply adding a reinforcing structure to the horizontal and vertical plates changes the strength, but it is still not ideal; 2. Moreover, since the entire dummy flag locking terminal is manufactured by directly setting multiple dummy flag locking terminals at intervals on a single strip, the dummy flag locking terminals need to be cut later. However, the current type of dummy flag locking terminal has the same strip thickness as the horizontal plate thickness, making later cutting inconvenient. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a false flag-type locking terminal to solve the problems mentioned in the background art, such as the inconvenience of cutting from the material strip in the later stage and the unsatisfactory overall strength.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a false flag-shaped locking terminal, comprising a strip, on which one or more false flag-shaped terminal bodies integrally formed with the strip are spaced apart. The false flag-shaped terminal body includes a base plate connected to the strip, and the base plate is provided with a terminal block and a female connector. The base plate has an L-shaped structure and includes a horizontal plate and a vertical plate connected to each other. The terminal block is disposed on the horizontal plate, and the female connector is disposed on the vertical plate. A reinforcing connecting flange strip perpendicular to the vertical plate is provided on the edge of the front side where the horizontal plate and the vertical plate are connected. A reinforcing rib is provided on the back side where the horizontal plate and the vertical plate are connected, and part of the reinforcing rib is located at the bottom of the horizontal plate and part is located at the bottom of the vertical plate. A through-hole groove is provided on the strip between two adjacent horizontal plates, and a V-shaped cutting groove is provided above each through-hole groove. The V-shaped cutting groove extends along the shearing direction of the strip.

[0006] Preferably, to improve overall strength, the height of the reinforcing connecting flange is greater than half the height of the plug-in female end.

[0007] Preferably, to improve the fixing effect of the male terminal, the terminal includes a cable wrapping piece for wrapping the cable portion and a core wrapping piece for wrapping the cable core portion, which are provided on the horizontal plate. The female terminal includes arc-shaped ears that are located on the left and right sides of the vertical plate and bend inward. There is a gap between the two arc-shaped ears. A locking spring is provided on the vertical plate between the two arc-shaped ears, with one end integrally formed with the vertical plate and the other end separated from the vertical plate and curving upward. The inner edges of the two arc-shaped ears are bent into upper pressure strips. The upper pressure strips cooperate with the locking spring below to form a locking part for clamping the male terminal. On the vertical plate, an inverted L-shaped lower pressure strip is provided on each side of the locking spring. The two inverted L-shaped lower pressure strips are mirrored. Each inverted L-shaped lower pressure strip cooperates with the arc-shaped ear on the same side to form a slot. The slot is connected to the locking part and the two ends of the slot are through. One end of the slot is close to the core wrapping piece, and the other end is away from the core wrapping piece.

[0008] As a preferred option, to improve the clamping effect of the male terminal block, a reinforcing rib extending along the length of the arc-shaped ear is provided on the inner side of each arc-shaped ear.

[0009] Preferably, the locking spring is provided with protruding locking points in order to achieve the locking and limiting function.

[0010] Preferably, to further improve the overall strength, the reinforcing rib extends along the length direction of the vertical plate.

[0011] Preferably, in order to achieve a clamping effect on the male terminal, the vertical plate is also provided with two elastic clamping groups, and each elastic clamp is aligned with the end of the slot away from the terminal. Each elastic clamping group includes two mirror-arranged triangular clamps, and the clamping jaws of the two triangular clamps on each elastic clamping group are arranged opposite each other.

[0012] Preferably, both the cable sheath and the core sheath have a U-shaped cross-section.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This structure further increases the overall strength of the vertical plate by providing a reinforcing rib on the back where the horizontal plate and the vertical plate are connected. Combined with the reinforcing connecting flange strip, the overall strength of the terminal is further increased, which can prevent accidental bending of the horizontal plate and the vertical plate and extend the service life of the terminal.

[0015] 2. In this structure, a through-hole groove is provided on the strip between two adjacent horizontal plates, and a V-shaped cutting groove is provided above each through-hole groove. During the subsequent cutting, the cost of the component is reduced, and the thickness of the cutting part is reduced due to the design of the V-shaped cutting groove. Ultimately, it is convenient to quickly cut along the V-shaped cutting groove. Therefore, this structure can facilitate the rapid cutting of two adjacent pseudo-flag-shaped terminal bodies.

[0025] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0026] Example 1:

[0027] Please see Figure 1-6 This embodiment provides a dummy flag-shaped locking terminal, including a strip 1. One or more dummy flag-shaped terminal bodies, integrally formed with the strip 1, are spaced apart on the strip 1. Each dummy flag-shaped terminal body includes a base plate 3 connected to the strip 1. The base plate 3 has a wiring terminal 4 and a female connector 15. The base plate 3 has an L-shaped structure and includes a horizontal plate 301 and a vertical plate 302 connected to each other. The wiring terminal 4 is disposed on the horizontal plate 301, and the female connector 15 is disposed on the vertical plate 302. A reinforcing connecting flange strip 5 perpendicular to the vertical plate 302 is provided on the front edge where plate 301 connects to the vertical plate 302. A reinforcing rib 6 is provided on the back side where the horizontal plate 301 connects to the vertical plate 302. The reinforcing rib 6 is partially located at the bottom of the horizontal plate 301 and partially located at the bottom of the vertical plate 302. A through-hole groove 7 is provided on the strip 1 between two adjacent horizontal plates 301. A V-shaped cutting groove 8 is provided above each through-hole groove 7. The V-shaped cutting groove 8 extends along the shearing direction of the strip 1.

[0028] Preferably, in order to improve the overall strength, the height of the reinforcing connecting flange 5 is greater than half the height of the plug-in female end 15.

[0029] Preferably, to improve the fixing effect of the male terminal, the terminal 4 includes a cable wrapping piece 401 for wrapping the cable portion and a core wrapping piece 402 for wrapping the cable core portion, both disposed on the horizontal plate 301. The female terminal 15 includes arc-shaped ears 9 located on the left and right sides of the vertical plate 302 and bent inwards, with a gap between the two arc-shaped ears 9. A locking spring piece 10 is disposed on the vertical plate 302 between the two arc-shaped ears 9, with one end integrally formed with the vertical plate 302 and the other end separate from the vertical plate 302 and curved upwards. An upper pressure strip 11 is bent into shape on the inner edge of the ear 9. The upper pressure strip 11 cooperates with the lower locking spring 10 to form a locking part for clamping the male terminal. On the vertical plate 302, an inverted L-shaped lower pressure strip 12 is provided on each side of the locking spring 10. The two inverted L-shaped lower pressure strips 12 are mirrored. Each inverted L-shaped lower pressure strip 12 cooperates with the arc-shaped ear 9 on the same side to form a slot 13. The slot 13 is connected to the locking part and the two ends of the slot 13 are through. One end of the slot 13 is close to the wire core wrapping sheet 402, and the other end is away from the wire core wrapping sheet 402.

[0030] Preferably, the cross-sections of the cable wrapping sheet 401 and the core wrapping sheet 402 are both U-shaped.

[0031] Preferably, in order to achieve a locking and limiting function, the locking spring 10 is provided with a protruding locking point 2. In this embodiment, the male terminal inserted into the slot 13 is locked and limited by the protruding locking point 2 on the locking spring 10.

[0032] Preferably, to further improve the overall strength, the reinforcing rib 6 extends along the length direction of the vertical plate 302. In this embodiment, the reinforcing rib 6 extends along the length direction of the vertical plate 302, which can further improve the overall strength of the final dummy flag-shaped terminal body.

[0033] In this embodiment, the male terminal's insert (not shown in the attached diagram) is inserted into the slot 13. The upper pressure strip 11 of the arc-shaped ear 9 and the inverted L-shaped lower pressure strip 12 on the vertical plate 302 elastically press the insert together, while the side of the insert is pressed against the inner wall of the arc-shaped ear 9. This further ensures the stability of the connection between the male terminal and the female terminal 15 and the locking effect of the male terminal, further enhancing the connection locking effect. Simultaneously, this structure further increases the overall strength of the vertical plate 302 by providing a reinforcing rib 6 on the back side where the horizontal plate 301 connects to the vertical plate 302. Furthermore, the height of the reinforcing connecting flange strip 5 is large. At half the height of the female connector 15, in conjunction with the bottom reinforcing rib 6, the overall strength of the terminal is further increased, which can prevent accidental bending of the horizontal plate 301 and the vertical plate 302, and extend the service life of the terminal. In addition, in this structure, a through-hole groove 7 is provided on the strip 1 between two adjacent horizontal plates 301, and a V-shaped cutting groove 8 is provided above each through-hole groove 7. During the subsequent cutting, the cost of the component is reduced, and the thickness of the cutting part is reduced due to the design of the V-shaped cutting groove 8. Ultimately, it is convenient to quickly cut along the V-shaped cutting groove 8. Therefore, this structure can facilitate the rapid cutting of two adjacent pseudo-flag-shaped terminal bodies.

[0034] In addition, the contact area between the male terminal insert and the female terminal insert 15 can be increased by using the upper pressure strip 11 in conjunction with the inverted L-shaped lower pressure strip 12, thereby enhancing the conductivity.

[0035] Example 2:

[0036] Please see Figure 7 This embodiment provides a pseudo-flag type locking terminal, which is preferred to improve the clamping effect on the male terminal. A reinforcing rib 2 14 extending along the length of the arc-shaped ear 9 is provided on the inner side of each arc-shaped ear 9. By providing the reinforcing rib 2 14 on the inner side of the arc-shaped ear 9, not only is the strength of the arc-shaped ear 9 increased and it is not easy to deform, but also when the male terminal is inserted into the slot 13 later, it is clamped in the middle with the L-shaped lower pressure strip 12 and the upper pressure strip 11. At the same time, the reinforcing rib 2 14 on both sides presses and clamps the male terminal, preventing the male terminal from falling out of the slot 13.

[0037] Example 2:

[0038] Please see Figure 8This embodiment provides a false flag-type locking terminal. Preferably, in order to achieve a clamping effect on the male terminal, the vertical plate 302 is also provided with two elastic clamping groups 16, and each elastic clamp is aligned with the end of the slot 13 away from the terminal 4. Each elastic clamping group 16 includes two mirror-arranged triangular clamps 161, and the clamping mouths of the two triangular clamps 161 on each elastic clamping group 16 are arranged opposite to each other. With the above structure, the portion of the male terminal exposed in the slot 13 can be clamped by the elastic clamping group 16, preventing the male terminal from moving at will, and preventing the male terminal from falling out of the slot 13.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
