Description

Technical Field

[0001] This utility model relates to the field of connector technology, specifically to a connector terminal connection structure. Background Technology

[0002] In electronic device connection systems, connector terminals are key components for achieving electrical connections, and the stability and reliability of their connection structure directly affect the overall performance of the device. As electronic devices evolve towards miniaturization and integration, higher demands are placed on the structural design and assembly processes of connector terminals.

[0003] Currently, most connector terminals on the market adopt a surface-mount structure. This presents numerous challenges, especially for terminals with dual leads and relatively long leads, during actual assembly. Figure 4 As shown. When such terminals are inserted into the socket of the housing, due to the long lead length, the connection between the lead and the shank often suffers from insufficient rigidity. During insertion, they are easily deformed by stress, and in severe cases, the leads may even bend and break, affecting the normal use and electrical connection performance of the terminals. Furthermore, the existing connection structure between the terminals and the housing lacks an effective insertion guidance mechanism, making it difficult to accurately align the terminals during insertion. This not only reduces assembly efficiency but also further increases the risk of lead damage. Therefore, it is urgent to design a new connector terminal connection structure to enhance the strength between the leads and the shank and optimize the insertion guidance function between the terminals and the housing, thereby solving the above-mentioned technical problems. Utility Model Content

[0004] In view of the shortcomings of the prior art, the present invention provides a connector terminal connection structure.

[0005] The technical solution adopted by this utility model is: a connector terminal connection structure, including a housing and terminals, wherein the terminals include a shank and pins, the bottom wall of the housing is provided with a plurality of sockets for pin insertion at intervals, the side walls between the shank and the pins are provided with a plurality of reinforcing guide strips at intervals, and the side walls of the sockets are provided with guide grooves that slide in cooperation with the reinforcing guide strips at intervals.

[0006] Furthermore, the cross-sections of the guide groove and the reinforcing guide strip are adapted to a "V" shape.

[0007] Furthermore, all of the aforementioned reinforcing guide strips consist of three strips.

[0008] Furthermore, the inner wall of the housing is provided with a sliding groove for connecting and engaging with the pin, the sliding groove is provided with a fitting groove, and the pin is provided with a boss that engages with the fitting groove.

[0009] Furthermore, the boss has a semi-elliptical structure.

[0010] Furthermore, the reinforcing guide strip has an inlet ramp at one end of the pin.

[0011] The beneficial effects of this utility model are:

[0012] First, by incorporating reinforcing guide strips on the sidewalls between the shank and the pin, the structural strength between the pin and the shank is effectively enhanced, mitigating the insufficient rigidity caused by the long pin. During the insertion of the terminal into the housing socket, the reinforcing guide strips disperse the stress, reducing the risk of deformation at the pin-shank connection and significantly lowering the probability of pin bending and breakage, thereby ensuring the stability and reliability of the terminal's electrical connection performance.

[0013] Secondly, the sliding fit between the guide strip and the guide grooves on both sides of the socket is enhanced, providing clear guidance for the insertion process of the terminal and the housing. This design ensures precise alignment of the terminal during insertion, effectively improving assembly efficiency. Simultaneously, precise guidance reduces additional damage to the pins caused by misalignment, further extending the terminal's lifespan.

[0014] Furthermore, the structure is simple and easy to implement, requiring no large-scale modification of existing production processes and equipment. While ensuring improved product quality, it effectively controls production costs, resulting in good economic benefits and promising market application prospects.

[0015] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0023] This utility model provides a connector terminal connection structure.

[0024] In this embodiment, refer to Figure 1-3 The connector terminal connection structure includes a housing 1 and a terminal 2. The terminal 2 includes a shank 3 and a pin 4. The bottom wall of the housing is provided with a plurality of sockets 5 for pin insertion. A plurality of reinforcing guide strips 6 are provided on the two side walls between the shank and the pin. Guide grooves 7 are provided on the two side walls of the sockets, which slide in cooperation with the reinforcing guide strips.

[0025] In the above technical solution, reinforcing guide strips are provided on both side walls between the terminal's shank and pin, and guide grooves that slide and engage with them are provided on both side walls of the housing socket. The reinforcing guide strips enhance the connection strength between the shank and pin, dispersing the stress on the pin during insertion. The guide grooves, in conjunction with the reinforcing guide strips, provide a guiding path for the terminal to be inserted into the housing, ensuring accurate insertion into the corresponding socket. This effectively solves the problem of insufficient rigidity in existing long-pin terminals, reducing bending and breakage of the pins during insertion. Simultaneously, the guiding structure improves the accuracy and smoothness of the terminal-housing connection, reduces assembly difficulty, and increases assembly efficiency.

[0026] In summary, by setting up guide reinforcement strips, the strength of the terminals is enhanced, and the sliding fit of the guide groove of the socket improves assembly accuracy and avoids the possibility of pins bending due to interference between the pins and the socket.

[0027] Specifically, the cross-sections of the guide groove and the reinforcing guide strip are adapted to a "V" shape.

[0028] In this embodiment, the cross-sections of the guide groove and the reinforcing guide strip are designed as a matching "V" shape. The "V" shape has good guidance and stability. During the terminal insertion process, the "V" shaped reinforcing guide strip cooperates with the guide groove to better guide the terminal to be inserted in the correct direction, and can automatically correct the position of the terminal during the insertion process, making the fit between the two more tight.

[0029] Specifically, there are three reinforcing guide strips.

[0030] In this embodiment, the number of reinforcing guide strips is set to three. The three reinforcing guide strips are reasonably distributed on the side wall between the handle and the pin, which can provide a more stable guiding and connection effect without increasing the weight and cost of the terminal structure while ensuring the strength of the terminal structure.

[0031] Specifically, the inner wall of the outer casing is provided with a sliding groove 8 for connecting and cooperating with the pin, the sliding groove 8 is provided with a fitting groove 9, and the pin is provided with a boss 10 that engages with the fitting groove.

[0032] In this embodiment, a sliding groove is provided on the inner wall of the housing to mate with the pin. A fitting groove is provided in the sliding groove, and a boss is provided on the pin to fit into it. When the terminal is inserted into the housing, the pin slides along the sliding groove, and the boss is embedded in the fitting groove to form a mechanical locking structure, which restricts the movement of the pin in the housing and achieves a firm connection between the terminal and the housing.

[0033] Specifically, the boss has a semi-elliptical structure.

[0034] In this embodiment, the boss is designed as a semi-elliptical structure, which helps to extend the service life of the boss and the fitting groove and reduce the problem of loose connection caused by wear; the good fit between the semi-elliptical boss and the fitting groove further enhances the stability and reliability of the connection between the pin and the housing.

[0035] Specifically, the reinforcing guide strip has an inlet ramp 11 at one end of the pin.

[0036] In this embodiment, a guide slope is provided at the end of the reinforcing guide strip located on one side of the pin. The guide slope can guide the reinforcing guide strip into the guide groove when the terminal is inserted into the housing, reduce insertion resistance, make the terminal easier to insert, and at the same time prevent the end of the reinforcing guide strip from being damaged by a hard collision with the edge of the guide groove.

[0037] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
