Description

Technical Field

[0001] This utility model relates to the field of connector technology, and in particular to an auxiliary device for connector welding. Background Technology

[0002] To date, electrical connectors have evolved into a comprehensive and specialized product line, characterized by a complete range of types and specifications, diverse structural forms, specialized focus, distinct industry characteristics, and standardized systems. Connectors are widely used in electric vehicles, electric forklifts, UPS systems, general power supplies, medical equipment, solar energy, and new energy fields.

[0003] Existing connectors typically consist of a plastic housing and terminals housed within the housing, connected via a PCB board. During assembly, the plastic housing terminals of existing connectors are usually directly inserted into the PCB board, and then soldered onto the PCB. However, before soldering, instability can cause the connector to tilt, making soldering difficult and potentially leading to incomplete soldering. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides an auxiliary device for connector welding, which can ensure the smooth welding of terminals.

[0005] The technical solution of this utility model is as follows: an auxiliary device for connector welding, including a support body, wherein a strip-shaped insertion hole for terminals to pass through is provided in the center of the support body; and multiple abutment parts for cooperating with the connector housing are provided at the upper and lower ends of one side wall of the support body.

[0006] Preferably, the upper and lower ends of the inner side of the strip-shaped insertion hole are provided with multiple protrusions, which abut against the terminal to better fix the terminal.

[0007] Preferably, the two opening sidewalls of the strip-shaped insertion hole are also provided with inclined surfaces that slope in the opposite direction to the opening.

[0008] Preferably, the abutting part is located at the upper and lower ends of one of the opening sidewalls of the strip-shaped insertion hole.

[0009] Preferably, the number of abutting parts is at least four, and they are symmetrically arranged on the side walls at the upper and lower ends of the opening.

[0010] Preferably, the contact position of the contact portion is an arc-shaped structure.

[0011] Preferably, the support body is made of plastic material.

[0012] Preferably, the strip-shaped insertion hole is also provided with escape holes on both sides to prevent the plastic support body from shrinking and forming air bubbles.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model can ensure smooth soldering of terminals through auxiliary devices and avoid connector tilting during the soldering process; 2. This utility model allows terminals to pass through a strip-shaped insertion hole and abuts against the connector housing through an abutting part, thus preventing the connector from tilting; 3. This utility model provides a protrusion inside the strip-shaped insertion hole, which abuts against the terminal, thereby better securing the terminal. 4. This utility model avoids shrinkage and air bubbles in the plastic support body through the escape hole, and at the same time can reduce the weight of the support body. Attached Figure Description

Detailed Implementation

[0015] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings: like Figure 1 and 2 As shown, this embodiment provides an auxiliary device for connector soldering, including a support body 1. A strip-shaped insertion hole 2 for inserting a terminal 20 is provided at the center of the support body 1. In this embodiment, the strip-shaped insertion hole 2 extends through both sides of the support body 1. Furthermore, multiple abutment portions 3 for cooperating with the connector housing 10 are provided at the upper and lower ends of one side wall of the support body 1.

[0016] In a preferred embodiment, the inner upper and lower ends of the strip-shaped insertion hole 2 are further provided with multiple protrusions 4. The number of protrusions 4 in this embodiment can be set according to the number of terminals 20. Generally, two protrusions 4 are provided for each terminal 20, and the two protrusions 4 are symmetrically arranged on the inner sides of the strip-shaped insertion hole 2 above and below the terminal 20. The protrusions 4 abut against the terminal 20, thereby better fixing the terminal 20.

[0017] In a preferred embodiment, the two opening sidewalls of the strip-shaped insertion hole 2 are also provided with inclined surfaces that slope in the opposite direction to the opening, thereby facilitating the insertion of the terminal 20.

[0018] In a preferred embodiment, the abutting portion 3 is disposed at the upper and lower ends of one of the opening sidewalls of the strip-shaped insertion through hole 2. In this embodiment, the number of abutting portions 3 is at least four, and they are symmetrically disposed on the sidewalls at the upper and lower ends of the opening of the strip-shaped insertion through hole 2. The abutting position of the abutting portion 3 is an arc-shaped structure to avoid scratching the connector housing 10 during the abutting process.

[0019] In this preferred embodiment, the support body 1 is made of plastic material. In this embodiment, escape holes 5 are also provided on both sides of the strip-shaped insertion hole 2 to prevent the plastic support body 1 from shrinking and releasing air bubbles.

[0020] like Figure 3 As shown, during use, by placing the support body 1 on the PCB board 30, and then passing the terminal 20 through the strip-shaped insertion hole 2, and making the abutment part 3 abut against the connector housing 10, the connector is fixed and prevented from tilting, thereby facilitating the smooth soldering of the soldering part of the terminal 20.

[0021] The embodiments and descriptions above are merely illustrative of the principles and preferred embodiments of this utility model. Various changes and modifications may be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of this utility model as claimed.
