The conductive pins 3 have multiple rows and are evenly arranged in the length direction of the insulating component. One end of the conductive pin 3 is bent to form a pin for fixing on a printed circuit board, and the other end extends straight to form a plug-in end for plugging and conducting with a matching connector. A guiding slope is provided at the inner edge of the plug-in side of the connector housing 1 to guide the matching connector when plugging.

[0031] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0032] The pin header connector of the utility model aims to solve the problem that when the number of cores of the conductive pins of the existing pin header connector changes, that is, when the length of the insulating component changes, the connector housing needs to be designed and processed for the mold, which leads to high mold development costs and high manufacturing costs of the pin header connector. In response to such problems, the utility model provides a brand-new pin header connector, which changes the one-piece connector housing of the traditional pin header connector and provides a new connector housing adapted to the insulating component of the pin header connector, that is, an end guide shell for the end of the insulating component. The end guide shells are used in pairs and are installed at both ends of the insulating component through the conductive pins of the insulating component when used. In this way, it can be used for insulating components of different lengths, and there is no need to re-open the mold of the connector housing for insulating components of different lengths. In this way, the manufacturing cost of pin header connectors of different specifications is reduced as a whole.

[0033] Based on such a design concept, different embodiments of the pin header connector of the present invention are specifically provided below for illustration.

[0034] Embodiment 1 of the pin header connector of the present utility model, as shown in FIG. Figure 2-6As shown, the pin header connector includes an insulating component 2 and an end guide shell installed at both ends of the insulating component 2. The insulating component 2 can be an existing insulating component 2. The end guide shell includes a main shell 1. The main shell 1 has a plug-in slot structure 11 for inserting the plug-in ends of the arrayed conductive pins 3 at the end positions of the insulating component 2. By inserting the arrayed conductive pins 3 at the end of the insulating component 2 into the plug-in slot structure 11, the insulating component 2 and the end guide shell can be fixedly installed. The side of the main shell 1 facing the other end guide shell is provided with relatively arranged guide walls. The guide walls are relatively arranged in the width direction of the insulating component 2, and the guide walls are parallel to the extension direction of the plug-in slot structure 11. The edge of the guide wall on one side facing away from the insulating component 2 is provided with a guide slope 100, so that a plug-in guide cavity 10 for the two ends of the adapter connector to enter is formed between the two guide walls. In a more preferred embodiment, as Figure 2 , 4 As shown, a guide key is provided on the guide wall to facilitate accurate guidance during the connector insertion process. At the same time, a guide key is provided on one of the two opposite guide walls to prevent wrong insertion.

[0035] It should be noted that the conductive pins 3 inserted in the insertion slot structure 11 play the role of fixing the end guide shell on the insulating component 2, and no longer plug and conduct with the adapter connector when in use. The conductive pins 3 in the plug-in guide cavity 10 of the two end guide shells and between the two end guide shells are plugged and conducted with the adapter connector. Because the arrangement of the conductive pins 3 on the insulating component 2 remains unchanged regardless of how the length of the insulating component 2 changes, the length change of the insulating component 2 will not affect the structure of the end guide shell, thus achieving the universality of the end guide shell, thereby reducing the manufacturing cost of the pin header connector.

[0036] There are many ways to fix the insulating component 2 and the end guide shell. For example, the insertion slot structure 11 is a through hole, and the hole depth of the insertion slot structure 11 is designed to be smaller than the length of the plug-in end of the conductive pin 3. After the conductive pins 3 in a row are inserted into the insertion slot structure 11, the conductive pins 3 have one end that passes through the insertion slot structure 11. The end is bent and flattened at the hole of the insertion slot structure 11 to achieve the fixed installation between the end guide shell and the insulating component 2. In another embodiment of the utility model, the insertion slot structure 11 is a forced slot, that is, the insertion slot structure 11 and the conductive pins 3 are forcedly matched, so as to achieve the fixation between the insulating component 2 and the end guide shell.

[0037] The end guide shell and the insulating component 2 are fixed by inserting the slot structure 11 and the conductive pins 3. As mentioned above, the conductive pins 3 arranged in a row at the end of the insulating component 2 play a fixing role and can no longer transmit electrical signals. Therefore, it is naturally hoped that the end guide shell can be inserted and fixed by an appropriate number of conductive pins 3, so as to play a reliable fixing role and retain as many conductive pins 3 as possible to transmit electrical signals. If only one row of conductive pins 3 is used to fix the end guide shell, that is, the slot structure 11 only corresponds to one row of conductive pins 3, then since the conductive pins 3 themselves are relatively small, and one row of conductive pins 3 generally has one or two conductive pins, the installation stability between the end guide shell and the insulating component 2 cannot be well guaranteed. Therefore, in one embodiment of the utility model, the end guide shell is fixedly installed by inserting two or more rows of conductive pins 3 and the insulating component 2. However, if the slot structure 11 for inserting the conductive pins 3 provided on the main shell 1 is a circumferentially sealed If the hole wall of a row of plug-in holes on the main shell 1 close to the other end guide shell is thicker, the plug-in of a row of conductive pins 3 adjacent to it in the plug-in guide cavity 10 will be affected. If the hole wall of a row of plug-in holes on the main shell 1 close to the other end guide shell is thinner, until it does not affect the plug-in of a row of conductive pins 3 adjacent to it in the plug-in guide cavity 10, the thickness of the hole wall is difficult to ensure during injection molding, resulting in a reduced yield and a higher processing cost.

[0038] In this regard, the utility model provides a preferred embodiment. The insertion slot structure 11 includes an insertion hole arranged in the main housing 1 and an insertion slot 12 arranged on the side of the main housing 1 facing the guide shell at the other end, and in the arrangement direction of the guide shells at both ends, the size of the insertion slot 12 is not greater than (i.e., less than or equal to) the size of the conductive pin 3. In this way, the spacing between the side of the guide shell of the main housing 1 facing the other end and the adjacent row of conductive pins 3 for insertion in the insertion guide cavity 10 is minimal and will not be less than the arrangement spacing of the row of conductive pins 3, which naturally will not affect the insertion of the row of conductive pins 3 closest to the main housing 1 with the adapter connector. Of course, at this time, the forced installation slot is forced to fit between the two slot walls and the conductive pins 3 in the thickness direction of the insulating component 2.

[0039] As a more preferred embodiment, Figure 2 , 4 As shown in Figures 5 and 6, in the arrangement direction of the guide shells at both ends, the size of the insertion slot 12 on the side of the main housing 1 facing the guide shell at the other end is equal to the size of the conductive pin 3, so that after the conductive pin 3 is inserted, the conductive pin 3 is flush with the groove edge of the insertion slot 12. In this way, the cavity wall of the insertion guide cavity 10 corresponding to both ends of the adapter connector can be a flat surface as a whole, which is convenient for inserting the adapter connector.

[0040] In such Figure 2 , 4 In the embodiment shown in FIG. 5 , there is one row of insertion holes in the main shell body 1, that is, the end guide shell is plugged and matched with the two rows of conductive pins 3 at the end of the insulating component 2 through one row of insertion holes and one row of insertion grooves 12, so as to realize the plug-in fixation between the insulating component 2 and the end guide shell. In other embodiments, the number of rows of insertion holes can be changed, such as two rows or three rows.

[0041] In another embodiment, the insertion slot structure 11 on the main housing 1 can be two rows of insertion slots 12 with notches facing each other, which are respectively inserted and matched with the two rows of conductive pins 3 at the end of the insulating component 2.

[0042] On the basis of any of the above embodiments, in an embodiment of a pin header connector of the utility model, as Figure 2-5 As shown, a positioning pin 13 is provided on the main housing 1 on one side of the insertion port of the insertion slot structure 11 for positioning with the positioning hole on the printed circuit board connected to the conductive pin 3 when in use. The positioning pin 13 facilitates the mounting and positioning of the pin header connector and the printed circuit board, which is convenient for manual mounting.

[0043] On the basis of any of the above embodiments, in an embodiment of a pin header connector of the utility model, as Figure 3-5 As shown, a receiving groove 15 for the end of the insulator to sink into during use is provided on the main housing 1 on one side of the insertion port of the insertion slot structure 11. The insulator is surrounded by the receiving groove 15, and the main housing 1 is closer to the printed circuit board, and the stability of the end guide shell is better during use. As a more preferred embodiment, the two groove walls of the receiving groove 15 are limit groove walls 14, that is, the receiving groove 15 is a limit groove adapted to the width of the insulator to limit the movement of the insulator in the width direction. In this way, it is possible to avoid the deformation of the conductive pin 3 inserted in the insertion slot structure 11 due to the misalignment of the end guide shell with the insulator in the width direction after the end guide shell is subjected to force, and further improve the stability of the fixed installation between the end guide shell and the insulating component 2.

[0044] In the above-mentioned different embodiments, the insulating component 2 can be an insulating component 2 in the prior art, that is, it includes a long rectangular insulating plate and a plurality of rows of conductive needles 3 inserted thereon, and the plurality of rows of conductive needles 3 are evenly spaced in the length direction of the insulating plate. The present invention also provides a more preferred embodiment. In this embodiment, Figure 2 and 6As shown, the insulating component 2 is a long strip-shaped plate-shaped insulator as a whole, and conductive pin 3 mounting holes are provided on it, which are penetrated along the plate thickness direction, so as to fix and install the conductive pin 3. These conductive pin 3 mounting holes are arranged in multiple rows, and the multiple rows of mounting holes are evenly spaced in the length direction of the insulator. The number of mounting holes in each row can be one, two or other numbers. In particular, the two opposite long side surfaces of the insulator are respectively provided with truncated grooves 21 evenly spaced along the length direction thereof (of course, in other embodiments, the truncated grooves 21 evenly spaced along the length direction thereof can also be provided on only one side surface of the two opposite long side surfaces), and each truncated groove 21 is located between two adjacent rows of conductive pin 3 mounting holes, so that when manufacturing the insulating component 2, a longer insulating component 2 can be manufactured, and then the length of the insulating component 2 is determined according to the number of conductive pins 3 cores actually required, and then the required insulating component 2 can be obtained by cutting at the position of the truncated groove 21. In order to facilitate cutting of the insulator, the truncated groove 21 is set through in the thickness direction of the insulator. The number of columns of mounting holes between two adjacent truncation grooves 21 can be set as needed. The more columns there are, the lower the truncation accuracy is, and the fewer the length values ​​that can be intercepted are. The fewer columns there are, the higher the truncation accuracy is, and the more the length values ​​that can be intercepted are. In this embodiment, in the length direction of the insulator, a column of the conductive needle 3 mounting holes is arranged between each two adjacent truncation grooves 21.

[0045] The embodiment of the end guide shell of the present invention has the same specific structure as the structure of the end guide shell in the pin header connector introduced above, which will not be described in detail herein.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The patent protection scope of the present invention shall be based on the claims. All equivalent structural changes made using the description and drawings of the present invention shall be included in the protection scope of the present invention.
