Detailed Description
The following description of the embodiments of the utility model is given by way of specific examples, the illustrations provided in the following examples merely illustrate the basic idea of the utility model, and the following examples and features of the examples can be combined with one another without conflict.
Referring to fig. 1, in the conventional pin header connector with two rows of pin headers, the two rows of pins 300 are all fixed by the fixing base 100, the stability of the end of the pin header 300 away from the fixing base 100 is poor, the pin header 300 is easy to deform due to external force during welding, and the pin header 300 is not easy to align during welding, thus easily causing product defects.

The present embodiment is described taking the example that the pin header connector includes a row of pins 301 connected to the upper portion of the fixing base 100 and a row of pins 302 disposed below the pins 301; of course, three or more rows of pins 300 may be provided. Each of the pins 301 includes a horizontal section 311 and a vertical section 321, respectively, and each of the pins 302 includes a horizontal section 312 and a vertical section 322, respectively. The horizontal section 311 and the horizontal section 312 are horizontally penetrated and fixed in the fixing base 100, and one ends of the horizontal section 311 and the horizontal section 312 are penetrated and fixed out of the fixing base 100 to form a connecting end. The vertical section 321 and the vertical section 322 are vertically penetrated and fixed in the supporting sheath 200, and one ends of the vertical section 321 and the vertical section 322 penetrate out of the supporting sheath 200 to form a welding end. Through setting up support sheath 200, can keep away from the one end of fixing base 100 to contact pin 301 and contact pin 302 to take place to warp when the welding after contact pin 301 and contact pin 302 receive the exogenic action, lead to vertical section 321 and vertical section 322 shift welding difficult alignment's problem effectively. The lower end surface of the fixing base 100 and the lower end surface of the supporting sheath 200 are disposed on the same horizontal plane, so that the pin header connector is kept stable after being soldered on a PCB (not shown).
Referring to fig. 4, in order to facilitate the fixing of the pins 301 and 302 with the fixing base 100, a row of horizontal insertion holes 101 are horizontally disposed at the upper portion of the fixing base 100, and a row of horizontal insertion holes 102 are horizontally disposed below the horizontal insertion holes 101. The horizontal jacks 101 are all located on the same horizontal plane, the horizontal jacks 102 are also all located on the same horizontal plane, and when three or more rows of horizontal jacks are arranged, the distances between two adjacent rows of horizontal jacks are equal. The horizontal jacks 101 are in one-to-one correspondence with the horizontal segments 311, and each horizontal segment 311 is respectively penetrated in the corresponding horizontal jack 101 and is in interference fit with the horizontal jack 101. The horizontal jacks 102 are in one-to-one correspondence with the horizontal segments 312, and each horizontal segment 312 is respectively inserted into the corresponding horizontal jack 102 and is in interference fit with the horizontal jack 102.
Referring to fig. 5, in order to facilitate the fixing of the pins 301 and 302 with the supporting sheath 200, the supporting sheath 200 is vertically provided with a row of vertical insertion holes 201 on a side far from the fixing base 100, and a row of vertical insertion holes 202 on a side near to the fixing base 100. The vertical jacks 201 are all located on the same vertical plane, the vertical jacks 202 are also all located on the same vertical plane, and when three or more rows of vertical jacks are arranged, the distances between two adjacent rows of vertical jacks are equal. The vertical jacks 201 are in one-to-one correspondence with the vertical sections 321, and each vertical section 321 is respectively arranged in the corresponding vertical jack 201 in a penetrating manner and in interference fit with the vertical jack 201. The vertical jacks 202 are in one-to-one correspondence with the vertical sections 322, and each vertical section 322 is respectively penetrated in the corresponding vertical jack 202 and is in interference fit with the vertical jack 202.
With continued reference to fig. 1, the dashed line in fig. 1 is a boundary between the exposed portion of the pin 300 and the portion extending into the PCB when the pin header connector is soldered to the PCB, i.e. the portion of the pin header 300 located below the dashed line extends into the PCB, and only the portion located above the dashed line can be connected to the supporting sheath 200. As can be seen from fig. 1, since the space between the horizontal portion of the inner pin 300 and the lower end surface of the fixing base 100 is small, the length d1 of the portion of the inner pin 300 that can be connected to the supporting sheath 200 is also small, thereby limiting the thickness of the supporting sheath 200, so that the supporting sheath 200 is too thin and is easily damaged when an external force is applied. In order to solve the above-mentioned problem, the present embodiment further provides a redundancy portion 110 in the fixing base 100, where the redundancy portion 110 is disposed between a horizontal jack corresponding to the lowest row of pins and a lower end surface of the fixing base 100. The space between the horizontal section 312 and the lower end surface of the fixing base 100 can be increased by providing the redundancy 110, so that the thickness of the support sheath 200 can be increased.
With continued reference to fig. 3 and 4, in order to fully utilize the existing device and avoid separately opening the mold of the fixing base 100 after the redundant portion 110 is provided, the double-row pin connector of the present embodiment directly adopts the fixing base 100 of the three-row pin connector, i.e. the horizontal jacks of the fixing base 100 are one row more than the pins, and the lowest row of horizontal jacks is not connected with the pins, so that the redundant portion 110 is formed between the horizontal jack corresponding to the lowest row of pins (i.e. the penultimate row of horizontal jacks) and the lower end surface of the fixing base 100. In particular to the present embodiment, the fixing base 100 is sequentially provided with a row of horizontal jacks 101, a row of horizontal jacks 102 and a row of horizontal jacks 103 from top to bottom, and the horizontal jacks 103 are all empty, so that the space between the horizontal segment 312 and the upper end surface of the fixing base 100 is equal to the space between the horizontal segment 312 and the lower end surface of the fixing base 100, and the space between the horizontal segment 312 and the lower end surface of the fixing base 100 is greater than the space between two adjacent rows of horizontal jacks in the prior art. At this time, the space between the horizontal segment 312 and the lower end surface of the fixing base 100 is larger, so that the length d2 of the connection portion between the inner pin 302 and the supporting sheath 200 is greater than the thickness of the fixing base 100, and thus the thickness of the supporting sheath 200 can be greater than or equal to the thickness of the fixing base 100, and the problem that the supporting sheath 200 is too thin and is easy to damage is solved.
With continued reference to fig. 5, in order to facilitate the accommodation of the solder overflowed during the soldering process when soldering the vertical segments 321 and 322 to the PCB, and the improvement of the heat dissipation effect of the vertical segments 321 and 322 during the soldering process, through slots 210 may be provided on the lower end surface of the supporting sheath 200 along the arrangement direction of the vertical jacks, so that the lower end openings of the vertical jacks 201 and 202 are located in the through slots 210, thereby leaving a gap between the supporting sheath 200 and the PCB to improve the heat dissipation efficiency. A vertical slot 220 may be further disposed on two side walls of the supporting sheath 200 at a position corresponding to a position between every two adjacent vertical jacks 201 (or vertical jacks 202), and a notch 221 communicating with the through slot 210 may be disposed at a lower end of each vertical slot 220, so as to further improve heat dissipation efficiency.
To facilitate positioning when the vertical sections 321 and 322 are inserted into the soldering holes of the PCB, at least two positioning posts 211 extending downward from the lower end surface of the support sheath 200 may be further disposed in the through-slot 210. Of course, at this time, positioning holes (not shown in the figure) corresponding to the positioning columns 211 are also formed on the PCB, and positioning of the pin header connector is achieved by matching the positioning columns 211 with the positioning holes. The positioning column 211 may be cylindrical, and a hemispherical arc portion 212 is disposed at the lower end of the positioning column 211, and the arc portion 212 may play a guiding role when the positioning column 211 is inserted into the positioning hole.
In this embodiment, the vertical section 321 and the vertical section 322 are fixed through the supporting sheath 200, so that the welding ends of the contact pin 301 and the contact pin 302 can be supported, and the problem that the welding ends are not easy to align due to deformation of the contact pin after the contact pin is subjected to external force during welding is effectively avoided. In addition, by providing the redundancy 110 at the lower portion of the fixing base 100, the length of the vertical section can be increased, thereby avoiding the problem that the vertical section of the innermost pin is too short to expose the PCB circuit board, thereby limiting the thickness of the supporting sheath 200, resulting in the supporting sheath 200 being too thin to be easily damaged.
Finally, it is noted that the above embodiments are only for illustrating the technical solution of the present utility model and not for limiting the same, and although the present utility model has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications and equivalents may be made thereto without departing from the spirit and scope of the present utility model, which is intended to be covered by the claims of the present utility model.
