Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.
The invention provides a connector based on the prior art, which has insufficient positioning precision and unreasonable performance, and the positioning structure of the connector further performs coarse positioning on the basis of the fine positioning by advanced fine positioning of the connector, so that the positioning of the connector is more reliable. The invention provides an invention of a connector, and the specific embodiment of the invention is as follows:
a connector according to an embodiment of the present invention is described in detail with reference to fig. 1 to 6.
Referring to fig. 1, a schematic structural diagram of a connector according to the present embodiment is shown. The present invention provides a connector, including: a first sub-connector 1, a second sub-connector 2 and a PIN 3.
The main body of the connector in this embodiment includes two major parts, one part is a first sub-connector 1 corresponding to a receptacle, and the other part is a second sub-connector 2 corresponding to a plug, and the connector can be operated only after the two sub-connectors are connected. Since the two sub-connectors need to be connected to each other, corresponding connection faces are provided on both sub-connectors. These two connection faces belong to the housing of the first sub-connector 1 and the second sub-connector 2, respectively, the housing of which can be a plastic housing or a housing made of another insulating material.
Referring to fig. 2, a schematic diagram of a first sub-connector structure of a connector according to the present embodiment is shown. The PIN bases 3 are distributed on the connecting surface side of the first sub-connector 1, the PIN bases 3 on the first sub-connector 1 are distributed on the connecting surface side of the first sub-connector 1 in parallel at equal intervals, and other modes can be adopted for distributing the PIN bases 3, such as: not equally spaced or side-by-side.
As shown in fig. 4, the PIN holder 3 according to the embodiment of the present invention includes at least two parts: a flat area 4 and a bent convex area 5 connected with the flat area 4. It should be noted that, regardless of how the PIN bases 3 are distributed on the connection surface side of the first sub-connector 1, the distribution area of the PIN bases 3 cannot occupy the peripheral area on the connection surface side of the first sub-connector 1.
Fig. 3 is a schematic diagram of a second sub-connector structure of the connector according to the present embodiment. In the embodiment of the present invention, PIN holes 6 are distributed on the connection surface side of the second sub-connector 2, the PIN holes 6 are distributed on the connection surface side of the second sub-connector 2 in parallel at equal intervals, and when the first sub-connector 1 is connected to the second sub-connector 2, the PIN holes 6 and the PIN bases 3 need to be in one-to-one correspondence. However, the PIN holes 6 may not be arranged in parallel at equal intervals, but in any case, the PIN holes 6 need to be arranged so as to correspond to the PIN bases 3, and the distribution area of the PIN holes 6 cannot occupy the peripheral area on the connection surface side of the second sub-connector 2.
Please refer to fig. 6, which shows a schematic diagram of the PIN and the PIN socket of the connector provided in this embodiment abutting against each other. The PIN holes 6 are distributed with PIN needles 7, and the PIN needles 7 penetrate through the PIN holes 6, when the first sub-connector 1 is connected with the second sub-connector 2 (as shown in fig. 1), the PIN needles 7 on the second sub-connector 2 are abutted with the flat areas 4 of the PIN bases 3 at the corresponding positions of the first sub-connector 1. Fig. 5 is a schematic diagram showing a PIN structure of a second word connector of the connector according to this embodiment. The PIN7 mentioned in this embodiment is cylindrical, and the end abutting against the second sub-connector has a structure in which the top is concave in the middle and convex in the periphery, and the PIN7 is generally cylindrical, but the diameter of the cross section at the two ends of the PIN7 is smaller than that of the middle section of the PIN.
Please refer to fig. 6, which shows a schematic diagram of the PIN and the PIN socket of the connector provided in this embodiment abutting against each other. Since the PIN7 is to be in contact with the flat region 4 of the PIN holder 3 at a position corresponding to the first sub-connector 1, only the raised portion of the PIN7 is in contact with the flat region 4, and thus, the width of the flat region 4 of the PIN holder is required to be not less than the diameter of the PIN7 corresponding thereto. The existing connector is characterized in that the PIN is contacted with a bent raised area of a PIN seat of a second sub-connector, but the contact surface of the bent raised area is a raised surface, so that the contact between the PIN and the PIN PIN seat is unstable. However, in the embodiment of the invention, the PIN7 is contacted with the flat area 4, so that the sufficient contact can be ensured when the PIN7 is abutted against the PIN seat 3, the resistance between the PIN7 and the PIN seat 3 is reduced, and the stable work of the connector is further ensured. Specifically, in the present embodiment, the PIN7 is in contact with the bent convex region 5 of the PIN holder 3, the position of the contact position is referred to as a contact position, and the contact position point is referred to as a pad point. There is a resistance value between the contact positions and the resistance value varies with the variation of the contact positions, and the magnitude of the resistance value between the contact positions of the PIN and the PIN holder in the prior art becomes unstable due to the instability of the contact positions. However, the connector is widely used for high-speed signal transmission, and the high-speed signal transmission requires a small resistance value and a stable resistance value of the channel, so that the connection of the resistance value of the channel between the PIN7 and the PIN base is required to be stable and reliable every time, and in this embodiment, the contact position of the PIN7 and the PIN base 3 is changed to stabilize the resistance value between the contact positions, so that the resistance value can further meet the requirement of high-speed signal transmission.
In order to further understand the improvement of the contact position between the PIN7 and the PIN holder 3 in the embodiment of the present invention, data analysis for the improvement is given below, and through the analysis, we can understand why the PIN7 of the second sub-connector 2 is selected to abut against the flat region 4 of the PIN holder 3 at the corresponding position of the first sub-connector 1 in the embodiment of the present invention. The relevant data for this connector is given below:
the width of the flat region 4 of the PIN holder 3 provided in the present embodiment is 0.18mm, and the width of the bent convex region 5 is 0.1 mm. It is desirable that the width of the PIN7 in embodiments be less than 0.18 mm.
The sequence number A in the graph represents the tolerance of the PIN with the starting point being the center of the PIN7 and the end point being the circular edge of the section of the PIN 7; b represents that the starting point is the circular edge of the section of the PIN needle 7, and the end point is the floating size of the gap of the circular edge of the section of the PIN needle 6; and the like for C-F. The data in the above chart is the data obtained when only the connector is precisely positioned, and the precise positioning block, the precise positioning frame and the precise positioning mentioned in the chart can be referred to below. At this time, the tolerance between the PIN holder 3 and the PIN7 can be calculated according to the chart and the corresponding data as follows: 0.005+0.02+0.01+0.02+0.02+0.03 is 0.105mm, the maximum error of the fit of the PIN holder 3 and the PIN7 is 0.088(3sigma) according to the 3sigma principle, and the width of the flat area 4 of the PIN1 PIN7 of the connector in the embodiment of the invention is 0.18mm, and the half is 0.09 mm; the width of the bending convex area 5 is 0.1mm, and the half width is 0.05mm, so that the following results are obtained: 0.05mm < 0.088mm < 0.09mm, the bent convex area 5 is not suitable for being used as a contact position of the PIN7 and the PIN seat 3, and the flat area 4 meets tolerance requirements and can be used as a contact position.
In summary, this embodiment is through changing PIN needle 7 with the contact position of PIN needle file 3, promptly PIN needle 7 with just right PIN pinhole 6 PIN needle file 3 flat region 4 butt can be more stable, reliable. When the contact position between the PIN7 and the PIN holder is stable, the resistance value of the resistance generated between the contact positions is also stable.
The connector in the embodiment of the invention needs to complete the contact between the PIN7 and the PIN base 3 when the connector is connected, and in order to ensure the connection of the connector, the connector provided in the embodiment of the invention further comprises a positioning structure, and the positioning structure is used for positioning when two sub-connectors are connected, namely positioning of the connector.
The existing connector only adopts a positioning mode to complete positioning when positioning, and although the positioning mode is convenient to operate, the connector is more and more widely applied in industrial production, and the positioning precision of the connector is higher and higher. The connector provided in the embodiment adopts double positioning of the connector, namely, the connector is firstly roughly positioned and then finely positioned on the basis of the rough positioning, so as to ensure the positioning precision of the connector. Therefore, the positioning structure of the connector provided in this embodiment includes two major structures, a coarse positioning structure 8 and a fine positioning structure 9, where the coarse positioning structure 8 is used to implement the advanced coarse positioning of the connector, and the fine positioning structure 9 is used to implement the further fine positioning of the connector, as shown in fig. 1.
In order to realize the coarse positioning of the positioning structure of the connector provided by the embodiment of the present invention, the coarse positioning structure 8 needs to be reasonably arranged on the connector, and the coarse positioning structure 8 includes two major parts: a coarse positioning block structure 11 and a coarse positioning frame structure 13, where the coarse positioning block module 11 needs to be disposed on the first sub-connector 1, specifically, the coarse positioning block module 11 is disposed on the connection surface side of the first sub-connector 1, and the sub-connectors are three-dimensional structures, so that the sub-connectors include different three-dimensional surfaces, and the connection surface is a contact surface of the two sub-connectors after the two sub-connectors of the connector are connected. As shown in fig. 2, the connection surface side of the first sub-connector 1 is provided with a groove provided in the periphery of the connection surface side of the first sub-connector 1, and the outermost side of the connection surface side may be provided with a groove structure slightly lower than the inside of the connection surface, or may be a groove of another type, such as: the outermost side of the connection surface side is set to be as high as a part of the inner side of the connection surface, and a groove or the like is formed in a portion between the outermost side of the connection surface side and the part of the inner side of the connection surface.
It should be noted that the grooves provided in this embodiment are grooves, and the grooves may be provided on both sides of the connection surface side of the first sub-connector 1, and since there are many connector shapes, the connection surfaces of both sub-connectors of the connector provided in this embodiment are rectangular. The notches are also provided on both sides of the narrow width of the connecting surface side. In other cases, the groove can also be arranged at other places on the periphery of the connecting surface side, such as: the entire periphery of the sub-connector connection surface side may be formed as a notch or other type of groove, or the periphery of the sub-connector connection surface side may be formed as a notch or other type of groove.
In order to realize the coarse positioning of the positioning structure, a coarse positioning frame module 13 is further required to be arranged on the second sub-connector 2, and the coarse positioning frame module 13 is arranged on the connection surface of the second sub-connector 2 and is matched with the coarse positioning block module 11 arranged on the connection surface side of the first sub-connector 1, so as to complete the coarse positioning of the connector provided by the embodiment of the invention. The structure of the coarse positioning frame module 13 is a frame structure, and in this embodiment, the frame structure is two half frame structures respectively disposed at two opposite ends of the connection surface of the second sub-connector 2, and the openings of the half frames are opposite. In order to cooperate with the coarse positioning block module 11, the size of the coarse positioning frame module 13 is set according to the size of the coarse positioning block module 11. In this embodiment, the coarse positioning block module 11 is a notch structure, so that the notch needs to be embedded into the frame structure to complete coarse positioning of the connector by the coarse positioning structure of the positioning structure. The size of the coarse positioning block module 13 is larger than that of the coarse positioning block module 11. It should be noted that the form of the frame structure in the embodiment of the present invention is various, for example, the frame structure is provided on all the peripheries of the connection surface sides of the second sub-connectors; or only a right-angled frame structure is respectively arranged at the diagonal angle of the connecting surface side of the second sub-connector, namely, the two half frame structures at the two opposite ends of the upper surface are cut by half and are reserved at the diagonal angle position of the connecting surface side; or the frame structure is arranged on two sides of the connecting surface side of the second sub-connector; the frame structure may also be provided as one whole, etc. But to ensure that the frame structure can fit into the above-mentioned groove.
Coarse positioning of the connector to accomplish the coarse positioning of the positioning structure. In this embodiment, the coarse positioning block module 11 may be embedded in the frame structure, or the coarse positioning block module 11 may be configured as a groove structure, and the frame structure may be embedded in the groove structure. How to match the different forms of grooves of the frame structure and the coarse positioning block module 11 is a flexible solution, and different treatments can be performed according to specific situations. However, the coarse positioning block module 11 can only be installed on the first sub-connector 1, and the coarse positioning frame module 13 needs to be correspondingly disposed on the second sub-connector 2.
The frame structure of the coarse positioning frame module 13 may be made of different materials according to different requirements, and the frame structure is a strip frame. The framework structure adopted in the embodiment is a zinc alloy strip-shaped framework.
The coarse positioning frame structure 13 is located outside the distribution positions of the PIN holes 6 and around the second sub-connector 2, and the coarse positioning block structure 11 is located outside the distribution positions of the PIN holes 7 and around the first sub-connector 1. Such a distribution may also allow the positioning structure to function as a protection for components on the connection face when positioning of the connector is completed.
After the coarse positioning of the first sub-connector 1 and the second sub-connector 2 is completed, in order to further ensure the positioning accuracy and the positioning stability of the first sub-connector 1 and the second sub-connector 2, the positioning structure of the connector provided by the present embodiment adds the fine positioning of the two connectors on the basis of the fine positioning.
In order to realize the precise positioning of the connector of the embodiment of the present invention by the positioning structure, the precise positioning structure 4 needs to be reasonably arranged on the connector, and the precise positioning structure 4 includes two major parts: a fine positioning block structure 10 and a fine positioning frame structure 12. In the present embodiment, the fine positioning block structure 10 is disposed on the connection surface side of the first connector 1, the fine positioning block structure 10 is a rounded bump structure extending outward, and two rounded bumps are disposed on both sides of the connection surface side of the first connector 1 in the present embodiment. Since the connection surfaces of the two sub-connectors of this embodiment are both rectangular, the two rounded bump structures are respectively located on the two sides of the connection surface side of the first sub-connector 1 with narrow width. The specific location of the fine positioning block structure 10 on the connection surface side of the first connector 1 can already be arranged appropriately according to the requirements of the connector. And the specific number of the fine positioning block structures is not strictly limited. The size of the rounded corner structure in this embodiment is 0.1mm, but this size may vary according to the size of the first sub-connector 1 and the tolerance requirements for the connector.
In order to realize the fine positioning of the positioning structure, it is necessary for the fine positioning structure 9 to further provide the fine positioning frame structure 12 on the second sub-connector, specifically, the fine positioning frame structure 12 is provided on the connecting surface side of the second sub-connector, and the fine positioning frame structure 12 is a chamfered protruding block protruding outwards. In order to correspond to the fine positioning block structure 10 in the present embodiment, the fine positioning frame structures 12 are provided on both sides of the second sub-connector 2 having a rectangular connecting surface and having a narrow width on the connecting surface side, and the positions where the fine positioning frame structures 12 are provided are changed in the second sub-connector 2 according to the change in the positions and the number of the fine positioning block structures 10 provided on the connecting surface side of the fine positioning block structure 10 on the first sub-connector 1. And the size of the chamfer structure is 0.1mm, namely the chamfer structure is matched with the size of the chamfer structure.
After the fine positioning block structure 10 and the fine positioning frame structure 12 are set, the chamfering structure of the fine positioning block structure 10 is slid into the chamfering structure, so as to complete the fine positioning of the first sub-connector 1 and the second sub-connector 2.
In the present embodiment, the fine positioning block structure 10 and the fine positioning frame structure 12 are respectively disposed on the connection surface sides of the first sub-connector 1 and the second sub-connector 2. However, since the two structures are similar, the positions can be interchanged, that is, the fine positioning block structure 10 and the fine positioning frame structure 12 are respectively disposed on the connection surface sides of the second sub-connector 2 and the first sub-connector 1. In combination with the positioning of the coarse positioning structures, i.e. the present embodiment may actually employ two sets of solutions for positioning the positioning structures on the connector. The first set is to arrange the coarse positioning block structure 11 and the fine positioning block structure 10 on the first sub-connector 1; the coarse positioning frame structure 13 and the fine positioning frame structure 7 are disposed on the second sub-connector 2. The second set is to arrange the coarse positioning block structure 11 and the fine positioning frame structure 12 on the first sub-connector 1; the coarse positioning frame structure 13 and the fine positioning block structure 10 are disposed on the second sub-connector 2. The first set of solutions is used in the present embodiment of the connector.
As can be seen from the above description, the size of the fillet of the fine positioning block structure 10 in this embodiment is 0.1mm, and the size of the chamfer of the fine positioning frame structure 12 is 0.1mm, and when the connector of this embodiment is only subjected to fine positioning, if the positioning errors of the two are within 0.1mm, the positioning block can slide into the positioning frame through the fillet. If the coarse positioning is further carried out on the basis of the original fine positioning, the allowable error range is expanded to 0.2mm, and the possibility of crushing the connector is greatly reduced. That is, after the fine positioning is added on the basis of the coarse positioning, the positioning accuracy mode of the positioning structure of the connector provided in the embodiment can be made reasonable, and the performance is stable, so that the occurrence of the situation of crushing the connector is reduced when the first sub-connector 1 and the second sub-connector 2 are positioned.
Moreover, the two sub-connectors in this embodiment may include a plurality of connector plastic members, for example, the connector plastic members may be distributed on the connecting surface sides of the two sub-connectors, and the connector plastic members may also be located at the distribution positions of the PIN PINs 7 and the PIN sockets 3. When the first sub-connector 1 is connected with the second sub-connector 2, namely, the connector is positioned, because the connector is additionally provided with the fine positioning on the basis of the thickening positioning, the positioning structure of the connector is accurate to the first sub-connector 1 and the second sub-connector 2, and the problem that the PIN needle 7 punctures the plastic part of the connector is avoided.
Although the present invention has been described with reference to the preferred embodiments, it is not intended to be limited thereto, and variations and modifications may be made by those skilled in the art without departing from the spirit and scope of the present invention.
