Description

Technical Field

[0001] This utility model relates to a connector, specifically a horizontal connector. Background Technology

[0002] Connectors are used in electronic devices to connect various components and enable signal transmission between them. There are many types of connectors, and different structural types must be selected for different types of electronic devices and internal installation space. Horizontal connectors are a commonly used type, and their traditional structure typically uses metal solder pads on both sides to ensure stability after soldering. However, this structure has several drawbacks: First, the solder pads increase assembly difficulty, leading to low production efficiency; second, the use of solder pads significantly increases product cost; third, traditional horizontal connectors lack effective positioning and error-proofing structures on the PCB board, easily causing connector pins to deviate from the PCB pads, resulting in poor soldering. This positioning inaccuracy is particularly pronounced in high-density installation environments, seriously affecting product reliability and yield. Furthermore, the positioning structure of traditional horizontal connectors often lacks sufficient strength, easily loosening during long-term use and affecting the stability of signal transmission. Summary of the Invention

[0003] To address the aforementioned technical problems, this invention provides a horizontal connector with a positioning function, which facilitates assembly and improves welding quality.

The bottom surface of the base is provided with a positioning post. A raised spacer is provided at the connection between the positioning post and the base. A boss is provided at the end of the positioning post. The boss protrudes laterally along the outer surface of the positioning post and has a chamfered structure.

[0012] As a further improvement, the upper surface of the base is provided with snap-fit ​​protrusions.

[0013] As a further improvement, the reinforcing rib is triangular in shape, with one side of the reinforcing rib connected to the lower surface of the base and the other side of the reinforcing rib connected to the flat surface of the positioning post.

For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0030] Example 1

[0031] like Figure 1-3As shown, a horizontal connector includes a base 1 and a plurality of pins 2. A portion of the pins 2 are inserted into and fixed within the base 1. The base 1 has a positioning post 3 on its bottom surface. A raised spacer 4 is provided at the connection between the positioning post 3 and the base 1. A boss 5 is provided at the end of the positioning post 3, protruding laterally along the outer surface of the positioning post 3. A chamfered structure 6 is provided on the boss 5. Pin holes with a spacing of 3.0 mm are provided on the base 1 for mounting the pins. Because the spacing of the pin holes is 3.0 mm, it is often referred to as a 3.0 mm pitch connector.

[0032] The positioning post 3 refers to a columnar structure extending perpendicularly to the bottom surface of the base. It can be manufactured integrally with the base using injection molding. Its function is to form a clearance fit with the positioning holes on the PCB board, achieving axial positioning during installation. The raised spacer is a strip-shaped protrusion forming around the base of the positioning post. It can be manufactured using mold forming. During PCB board soldering, it supports the product, creating a gap for heat dissipation and preventing solder run-through. The boss is a stepped structure extending outward from the end of the positioning post. It can be designed as a disc-shaped structure with a diameter larger than the main body of the positioning post. Its lateral protrusion can contact the PCB board surface to form a support surface, preventing it from easily falling off after assembly. The chamfered structure refers to the beveled or rounded transition of the boss's edge. A 45-degree chamfer can be used to guide the positioning post smoothly into the mounting holes on the PCB board, improving the ease of insertion.

[0033] Specifically, when the connector is installed on the PCB board, the positioning post 3 inserts into the corresponding positioning hole on the PCB board, serving as a positioning guide. After soldering, it can fix the connector. The lateral extension of the boss 5 abuts against the surface of the PCB board. The chamfered structure 6 allows the boss 5 to automatically adjust its position during insertion. The chamfered structure 6 makes it easier for the positioning post 3 to be inserted into the PCB board, and the boss makes it less likely for the connector inserted into the PCB board to fall out. The boss is usually made of silicone-like material, which has a certain degree of elasticity. After being inserted into the positioning hole of the PCB board, it forms a lock from the other side, preventing it from falling out.

[0034] Compared to existing technologies, traditional horizontal connectors rely on metal solder pads for welding and fixing, requiring additional processing and assembly steps. This solution, however, utilizes a positioning post and boss structure integrated into the base bottom, achieving dual positioning functionality while reducing the number of parts. Existing technologies often lack chamfering designs, leading to increased installation resistance. This solution, with its chamfered boss structure, facilitates a smoother assembly process and reduces the precision requirements for PCB board hole machining.

[0035] Through the above technical solution, this application solves the problems of complex assembly and insufficient positioning accuracy of traditional horizontal connectors.

[0036] The boss is integrally formed on the positioning post, and the raised partition strip and the positioning post are integrally formed structures, which avoids the risk of loosening caused by separate assembly, and also reduces costs. It can be directly formed in a mold without separate assembly, reducing the number of processes.

[0037] Example 2

[0038] like Figure 1-3 As shown, one side of the positioning post 3 is provided as a flat surface 7 along the axial direction. The flat surface 7 refers to the flat side extending along the axial direction of the positioning post 3, which can be formed by cutting or mold forming process, and can fit with the corresponding plane of the external structure, restricting the circumferential rotation of the positioning post and ensuring that the connector maintains the correct orientation during installation.

[0039] Specifically, after setting a positioning post 3 with a flat surface on the bottom surface of the base 1, when the connector is installed on the PCB board, the flat surface 7 of the positioning post 3 fits tightly with the corresponding planar structure on the PCB board. This planar fit method can effectively prevent circumferential displacement of the connector during soldering, ensuring accurate alignment of the pins and pads. At the same time, the flat surface simplifies the fit between the positioning post and the external structure, enabling directional installation without the need for additional complex foolproof structures.

[0040] Compared to existing technologies, traditional horizontal connectors often use circumferentially symmetrical circular positioning posts, which can easily lead to inaccurate circumferential positioning during installation. However, by making one side of the positioning post a flat surface, rapid directional installation can be achieved, reducing manufacturing complexity and improving assembly efficiency.

[0041] Through the above technical solution, this application can effectively solve the circumferential misalignment problem that occurs when the connector is installed on the PCB board, ensuring precise alignment between the pins and the pads. The mating method of the flat surface and the corresponding structure significantly improves the soldering stability, while simplifying the overall structural design of the connector and reducing manufacturing costs.

[0042] Furthermore, the flat surface 7 on one side can prevent turnover during assembly, thus improving the stability of the assembly.

[0043] In addition, a reinforcing rib 8 is provided on one side of the positioning post 3, and the reinforcing rib 8 is connected to the lower surface of the base 1. The reinforcing rib 8 is triangular in shape, with one side connected to the lower surface of the base and the other side connected to the flat surface of the positioning post.

[0044] The reinforcing rib 8 is a support structure located on the side of the positioning post 3. Specifically, it can be implemented using a triangular or trapezoidal protrusion structure to enhance the connection strength between the positioning post and the base and prevent the positioning post from deforming under stress.

[0045] The flat surface on one side of positioning post 3 is rigidly connected to the lower surface of the base by adding reinforcing ribs. When the connector is subjected to external forces, the reinforcing ribs can distribute the load applied to the positioning post, preventing the positioning post from tilting or breaking due to unilateral force. During the soldering process, the reinforcing ribs can limit the displacement of the positioning post, ensuring the positioning accuracy between the connector and the PCB board.

[0046] Compared to existing technologies, traditional horizontal connectors lack a supporting structure for their positioning posts, making them susceptible to displacement due to external forces during welding or mating. This solution addresses this by incorporating reinforcing ribs on the sides of the positioning posts that are directly connected to the base, creating a stable three-point support structure that effectively enhances the positioning posts' resistance to deformation and increases their strength.

[0047] Through the above technical solution, this application solves the problem of weld foot deviation caused by deformation of the positioning post during connector welding. The support of the reinforcing rib ensures the stability of the positioning post during the welding process, thereby improving welding accuracy and product reliability.

[0048] Example 3

[0049] like Figure 1-3 As shown, the base 1 is provided with a number of anti-fool holes 9. The number of anti-fool holes 9 is the same as the number of PIN pins 2. After the PIN is inserted into the base, it extends into the anti-fool holes.

[0050] The shapes of the plurality of anti-mistake holes 9 are irregular, or some of the anti-mistake holes are regular in shape while the remaining anti-mistake holes are irregular in shape.

[0051] The "foolproof hole" (9) refers to a hole structure used to prevent incorrect installation orientation or position. Specifically, it can be implemented using irregular hole shapes that match the shape of the PIN pin, such as polygonal or asymmetrical shapes. The shape difference restricts the insertion direction of the PIN pin. For example, some holes use circles as reference positioning holes, while the remaining holes use pentagons or squares with chamfered corners as anti-misalignment holes. When the PIN pin is inserted into the base, its extended end must perfectly match the shape of the anti-foolproof hole; if the installation orientation is incorrect, insertion cannot be completed. This structure forces operators to align the pin according to a preset direction during assembly, thus avoiding soldering misalignment caused by rotation or offset.

[0052] In this embodiment, four pins are provided, and four anti-fool holes are provided accordingly. One anti-fool hole is a regular rectangle, and the other three anti-fool holes have an inclined surface on one side. The inclined surface extends along the depth direction of the anti-fool hole, which can play an effective role in preventing mistakes during assembly.

[0053] The extension of the PIN pin into the anti-fool hole means that after the PIN pin is inserted into the base, its end is embedded inside the anti-fool hole. This can be achieved by adjusting the length of the PIN pin or the depth of the anti-fool hole, so that the end of the PIN pin and the anti-fool hole form a physical limit.

[0054] Specifically, the number of keying holes is the same as the number of pins, ensuring that each pin corresponds to a unique keying hole when inserted into the base. After insertion, the pin's end extends into the corresponding keying hole, facilitating connection to other components. Because the shape or distribution of the keying holes is unique, operators cannot incorrectly insert pins into other positions, thus preventing solder pads from deviating from the PCB pads during soldering.

[0055] Compared to existing technologies, traditional horizontal connectors rely on metal solder pads for positioning, but lack independent foolproof structures for the pins, making them prone to misalignment or incorrect orientation during assembly. This solution directly constrains the position of each pin through a one-to-one correspondence between foolproof holes and pins, as well as physical limiting effects, achieving precise positioning without relying on external solder pads.

[0056] Through the above technical solution, this application can ensure that the installation position of the PIN pin in the base is unique and fixed, eliminate the soldering offset problem caused by human operation error, and reduce the dependence on auxiliary positioning structure during assembly, thereby reducing production costs and improving soldering yield.

[0057] The upper surface of the base 1 is provided with a snap-fit ​​protrusion 10. The snap-fit ​​protrusion 10 refers to a local raised structure formed on the upper surface of the base 1, which can be implemented by a block protrusion with a trapezoidal or semi-circular cross section.

[0058] The snap-fit ​​protrusion is usually located on the side of the anti-fool hole. It works with the snap-fit ​​protrusion to engage with the snap-fit ​​on the wire connector, thereby improving the stability of the assembly.

[0059] The base has guide inclined sides on both sides. These guide inclined sides refer to the inclined surfaces formed by the edges of the base, which can be achieved through bevel cutting or injection molding. The inclined surfaces form a guiding fit with the structure of the installation position. These inclined sides guide the connector during insertion, ensuring it accurately enters the installation position along a predetermined direction, avoiding solder joint misalignment due to positional deviation.

[0060] Specifically, during assembly with the wire-end connector, the guide angled sides on both sides of the base guide the connector to the correct position through a gradually narrowing gap. This forces the connector to automatically adjust to the target position, improving assembly accuracy.

[0061] It should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the 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. However, 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.
