Description

Technical Field

[0001] This utility model relates to the technical field of automotive wiring harness connection, and in particular to a connector and its short contact spring terminal. Background Technology

[0002] Automotive wiring harnesses are interconnected via connectors, achieving electrical conductivity through male and female terminals within the connectors. Most existing automotive male and female terminals use a straight-line mating design, with the mating interfaces on the same plane. This means the female terminal has a long, strip-shaped spring on its inner wall, which deforms to achieve mating. To ensure proper mating, the spring needs a certain length, resulting in a corresponding increase in the overall length of the female terminal, making it unsuitable for the confined spaces of a vehicle. Therefore, an improvement is needed. Utility Model Content

[0003] The purpose of this invention is to provide a short-contact spring terminal to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] This utility model discloses a short contact spring terminal, including an integrally formed terminal body and a crimping part. The terminal body is a box structure with openings at both ends, and an interface for male terminal insertion is formed inside it. A contact spring is provided in the interface, and the contact spring is connected to the side wall of the terminal body through a side wing unfolding piece.

[0006] Furthermore, in the aforementioned short contact spring terminal, the contact spring and the side wing unfolding piece are integrally formed with the terminal body.

[0007] Furthermore, in the aforementioned short contact spring terminal, a guide slope is provided at the end of the contact spring away from the crimping portion.

[0008] Furthermore, in the aforementioned short contact spring terminal, a limiting boss protrudes from the inner wall of the end of the interface opposite to the crimping portion.

[0009] Furthermore, in the aforementioned short contact spring terminal, the outer wall of the terminal body has a retaining portion protruding.

[0010] This utility model discloses a connector including the aforementioned short contact spring terminal.

[0011] Compared with the prior art, the advantages of this utility model are as follows: The short contact spring terminal structure of this utility model is simple. The contact spring is connected to the side wall of the terminal body through the side wing unfolding piece. When the male terminal is inserted into the interface, the terminal contact spring is pressed down first, and then the side wing unfolding piece is driven to complete the mating. The contact spring and the side wing unfolding piece change the original single-axis deformation of the traditional terminal to complete the mating, and the mating is completed by dual-axis linkage, which reduces the structural length required for single-axis deformation, thereby achieving the purpose of reducing the overall size of the female terminal.

[0019] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "mounted", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements.

[0020] See Figures 1 to 4 As shown, a short-contact spring terminal includes an integrally formed terminal body 1 and a crimping portion 2. The terminal body 1 is a box structure with openings at both ends, and an interface for inserting a male terminal is formed inside it. A contact spring 11 is arranged in the interface, and the contact spring 11 is connected to the side wall of the terminal body 1 through a flank expansion piece 111.

[0021] In this technical solution, the crimping portion is a conventional structure and is used for physically connecting and electrically connecting one end of a wire harness. The contact spring is connected to the side wall of the terminal body through a flank expansion piece. When the male terminal is inserted into the interface, the terminal contact spring is first pressed down, and then the flank expansion piece is带动, so as to complete the mating. The contact spring and the flank expansion piece change the single-axis deformation of the original traditional terminal to complete the mating into a two-axis联动 to complete the mating, reducing the structural length required for single-axis deformation, thereby achieving the purpose of reducing the overall size of the female terminal.

[0022] Exemplarily, see Figures 1 to 4 As shown, the contact spring 11 and the flank expansion piece 111 are integrally formed with the terminal body 1.

[0023] In this technical solution, the terminal body, contact spring, side wing unfolding piece, and crimping part are integrally formed from the same metal sheet through processes such as stamping. The terminal body includes a bottom wall, a first side wall, a top wall, and a second side wall that form a box structure. The second side wall is a two-section structure, including an upper side wall connected to the top wall and a bottom side wall connected to the bottom wall. The contact spring and the side wing unfolding piece are formed by bending the upper side wall into the box. The contact spring is parallel to the bottom wall and the top wall. The top of the first side wall, the top wall, and the upper side wall are slotted and divided into front and rear ends to facilitate the individual bending of the contact spring and the side wing unfolding piece.

[0024] For example, see Figure 1 and Figure 4 As shown, a guide slope is provided at the end of the contact spring 11 that is away from the pressing part 2.

[0025] In this technical solution, the guide slope facilitates the quick insertion of the male terminal between the contact spring and the top wall.

[0026] For example, see Figure 1 , Figure 3 and Figure 4 As shown, a limiting boss protrudes from the inner wall of one end of the interface away from the crimping part 2.

[0027] In this technical solution, the corresponding top surface of the male terminal is recessed with a limiting groove corresponding to the limiting boss. After the male terminal checks the female terminal, the limiting boss and the limiting groove limit the male terminal to avoid poor contact caused by shaking between the male terminal and the female terminal.

[0028] For example, see Figures 1 to 4 As shown, the outer wall of the terminal body 1 has a retaining portion protruding.

[0029] In this technical solution, the anti-retraction part corresponds to the groove inside the connector housing to prevent the short-contact spring terminal from falling off the connector housing.

[0030] For example, a connector includes the aforementioned short contact spring terminal.

[0031] In this technical solution, the connector housing is an existing structure. After the short contact spring terminal and the wire harness are crimped together, they can be inserted into the connector housing. After the male and female terminals are matched, the overall length can be reduced by about 6mm, that is, the overall wire harness can also be reduced by about 6mm, which is suitable for arrangement in the narrow space of a vehicle.

[0032] In summary, this short contact spring terminal has a simple structure. The contact spring is connected to the side wall of the terminal body through the side wing unfolding piece. When the male terminal is inserted into the interface, the terminal contact spring is pressed down first, and then the side wing unfolding piece is driven to complete the mating. The contact spring and the side wing unfolding piece change the original single-axis deformation of the traditional terminal to complete the mating, and the mating is completed by dual-axis linkage, which reduces the structural length required for single-axis deformation, thereby achieving the purpose of reducing the overall size of the female terminal.

[0033] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0034] The above description is only a specific embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
