Definitions

  • the present application relates to the field of electrical connection, in particular, to a receptor connector.
  • the receptor connector is widely applicable to various electric apparatus. Terminal pins of the receptor connector are connected to a substrate (for example, a printed circuit board) by soldering to achieve signal transmission. Generally, when the receptor connector is soldered to the substrate, it requires inserting the terminal pins into the soldering holes in the substrate and then performing the soldering operation. In the process of inserting the terminal pins, it is necessary to ensure that the pins are accurately aligned with the soldering holes on the substrate to prevent the pins from bending. In addition, in order to prevent the receptor connector from moving during the soldering process which may influence the soldering accuracy, it is necessary to apply a self-weight fixation to the receptor connector to allow a firm connection of the receptor connector with the substrate.
  • the conventional receptor connector achieves the alignment of its mounting position either by providing a positioning portion on the housing of the receptor connector or by providing ear clips on the housing to perform the self-weight fixation after insertion, which only achieves one of the positioning function and the fixing function.
  • the terminal pins are prone to bending or the soldering is performed with a low accuracy, which impact the product quality and cause a complicated soldering operation and a low soldering efficiency.
  • such receptor connector and substrate have a high rejection rate of product, thereby significantly impacting the cost of the production.
  • the object of the present application is to provide a receptor connector to solve the technical problems of conventional receptor connector with a low soldering efficiency, a low quality of the product, and a high cost of the production.
  • a receptor connector comprises a housing and a pin assembly including a plurality of terminal pins each of which is partially provided inside the housing and partially extended to the outside of the housing, the receptor connector further includes at least two positioning fixation posts which are provided on the housing and spaced apart from each other, the positioning fixation post comprising a connecting portion with one end thereof connected to the housing, a positioning portion, and a fixing portion on which a locking protrusion is provided, the positioning portion and the fixing portion being connected to the other end of the connecting portion and being provided with a gap therebetween.
  • the positioning fixation posts are formed by being extended outwardly from the housing along the extending direction of the terminal pins.
  • the end of the positioning portion is provided with a first chamfer.
  • the end of the fixing portion is provided with a second chamfer.

  • the positioning fixation posts are integrally molded with the housing.
  • the receptor connector described above are provided with positioning fixation posts on the housing, the positioning fixation posts comprise a connecting portion with one end thereof connected to the housing, a positioning portion, and a fixing portion on which a locking protrusion is provided, the positioning portion and the fixing portion are connected to the other end of the connecting portion and are provided with a gap therebetween.
  • the positioning portions are firstly aligned with the positioning holes in the substrate, thereafter, the receptor connector is pushed to allow the positioning portions to be inserted into the positioning holes along with the fixing portions pressed into the positioning holes.
  • the locking protrusions come into contact with the substrate in the positioning holes, and the receptor connector is further pushed so that the substrate presses against the locking protrusions to make the fixing portions elastically deformed. After the locking protrusions are completely inserted into the positioning portions through the substrate, the locking protrusions are restored and stuck on the substrate to make the receptor connector firmly connected with the substrate.
  • the receptor connector described above can achieve the positioning and alignment of the soldering installation and the self-weight fixation at the same time. Thus, it is possible to ensure the terminal pins to be accurately inserted into the soldering holes to avoid the bending of the terminal pins, while ensure the stability of the connection between the receptor connector and the substrate during the soldering process.

In practice, the number and the set location of the positioning fixation posts 13 can be provided specifically as practical needs, which are not limited specifically in the present embodiment.
  • the end of the positioning portion 132 is provided with a first chamfer 1321 which is capable to serve as a guidance in the alignment of the positioning portion 132 with the substrate so that even if the position of the positioning portion 132 slightly shifts during the alignment, the positioning portion 132 is able to slip into the positioning hole.
