Describe the USB joint fixed structure of the utility model embodiment with reference to the accompanying drawings in detail.
As depicted in figs. 1 and 2, according to the USB joint fixed structure of the utility model embodiment, USB joint 1 has USB leg 11, and USB joint 1 is welded on pcb board 2 by USB leg 11.
Specifically, pcb board 2 is provided with the welding hole 201 of through pcb board 2, the end of USB leg 11 to extend in welding hole 201 and welds with pcb board 2, and the gauge of USB leg 11 end is less than the width dimensions of welding hole 201, that is between the end of USB leg 11 and the inwall of welding hole 201, there is gap, thus scolding tin can be entered in gap, the side that USB leg 11 extend into the part in welding hole 201 is formed with tin hole (not shown), in welding process, scolding tin also will enter in tin hole.
According to the USB joint fixed structure of the utility model embodiment, by arranging tin hole on USB leg 11, make scolding tin can enter in tin hole, thus by means of only scolding tin, the inner surface of the side of USB leg 11 with welding hole 201 is not connected together, and scolding tin also enters in tin hole, thus the weld strength increased further between USB leg 11 and pcb board 2, reducing improper use causes USB joint from the situation of sealing-off pcb board, improves the stability of USB joint permanent joint.
The schematic diagram that the USB leg 11 that Fig. 2 shows the utility model embodiment welds with pcb board 2, wherein, in figure, saturating tin hole is covered by scolding tin, therefore not shown.
As shown in Figure 2, in embodiments more of the present utility model, saturating tin hole is along the end of the through USB leg 11 of thickness direction of USB leg 11, and the end surfaces of tin hole and USB leg 11 is opened thoroughly.In addition, USB leg 11 to stretch between the side of the part of welding hole 201 and the inner surface of welding hole 201 and thoroughly all has the scolding tin 3 for welding USB leg 11 and pcb board 2 in tin hole.When USB leg is welded on pcb board, scolding tin 3 can form the syndeton of " H " shape at USB leg 11 and the weld of pcb board 2, thus by this syndeton by USB leg 11 and stable the connecting together of pcb board 2, improve the bonding strength between USB leg 11 and pcb board 2.
The saturating tin hole of this through USB leg 11 can be multiple, in addition, also can form the one or more tin holes in blind hole shape on the side of USB leg 11.
Further, the diameter in saturating tin hole is in the scope of 0.2 millimeter to 0.4 millimeter.Thus, can ensure that scolding tin 3 enters in tin hole, but also the intensity that excessive saturating tin hole has influence on USB leg 11 can be avoided the formation of.
Certainly, foregoing description is not the restriction to saturating tin hole dimension, it is only a specific embodiment of the present utility model, when affecting the intensity of USB leg 11 and can ensureing that scolding tin enters in tin hole, tin hole of the present utility model is the poroid of other shape or size, such as diameter is arranged in the circular hole being less than 0.2 millimeter or be greater than within the scope of 0.4 millimeter in saturating tin hole, or it is poroid, oval poroid, spherical poroid etc. saturating tin hole to be arranged to polygon.
Preferably, saturating tin hole is formed by punching press.Thus make tin hole forming convenient, improve the shaping efficiency of USB joint 1.
As shown in Figure 1, in examples more of the present utility model, USB leg 11 is multiple, and pcb board 2 has and multiple USB leg 11 welding hole 201 one to one.Thus the weld strength that can improve further between USB joint and pcb board.
Advantageously, as shown in Figure 1, the edge of pcb board 2 is formed with gap slot 202, USB joint 1 be engaged in gap slot 202 at least partially, the relative both sides of USB joint 1 are equipped with USB leg 11.Thus, not only effectively can save the space that USB joint 1 takies, improve space availability ratio, but also welded intensity between USB joint and pcb board can be improved further.
The utility model also proposed a kind of USB joint, and this USB joint 1 comprises USB leg 11, and the side of the end of USB leg 11 is formed with tin hole.Thus, when this USB joint 1 being welded on pcb board, the intensity of welding point can be improved.
As shown in Figure 2, saturating tin hole is along the end of the through USB leg 11 of thickness direction of USB leg 11, and the end surfaces of tin hole and USB leg 11 is opened thoroughly.Be welded in the process of pcb board by this USB joint, USB leg 11 to stretch between the side of the part of welding hole 201 and the inner surface of welding hole 201 and thoroughly all has the scolding tin 3 for welding USB leg 11 and pcb board 2 in tin hole.When USB leg is welded on pcb board, scolding tin 3 can form the syndeton of " H " shape at USB leg 11 and the weld of pcb board 2, thus by this syndeton by USB leg 11 and stable the connecting together of pcb board 2, improve the bonding strength between USB leg 11 and pcb board 2.
Advantageously, the diameter in saturating tin hole is in the scope of 0.2 millimeter to 0.4 millimeter.Thus, can ensure that scolding tin 3 enters in tin hole, but also the intensity that excessive saturating tin hole has influence on USB leg 11 can be avoided the formation of.
Certainly, foregoing description is not the restriction to saturating tin hole dimension, it is only a specific embodiment of the present utility model, when affecting the intensity of USB leg 11 and can ensureing that scolding tin enters in tin hole, tin hole of the present utility model is the poroid of other shape or size, such as diameter is arranged in the circular hole being less than 0.2 millimeter or be greater than within the scope of 0.4 millimeter in saturating tin hole, or it is poroid, oval poroid, spherical poroid etc. saturating tin hole to be arranged to polygon.
In the description of this specification, specific features, structure, material or feature that the description of reference term " embodiment ", " some embodiments ", " example ", " concrete example " or " some examples " etc. means to describe in conjunction with this embodiment or example are contained at least one embodiment of the present utility model or example.In this manual, to the schematic representation of above-mentioned term not must for be identical embodiment or example.And the specific features of description, structure, material or feature can combine in an appropriate manner in any one or more embodiment or example.In addition, the different embodiment described in this specification or example can carry out engaging and combining by those skilled in the art.
