Description

Heightening row needle

Technical Field

The utility model relates to a heightening pin header belongs to connector technical field.

Background

The pin header is generally widely applied to connection of a PCB (printed circuit board), has the name of a universal connector, and is generally matched with the universal connector for use, and comprises a header bus, a line terminal and other connectors; the pin header is widely applied to PCB circuit boards in electronics, electrical appliances and instruments, and the blocked part or isolated and non-communicated circuits in the circuit play a role of a bridge and take charge of the task of current or signal transmission; the connecting plate is usually matched with a row bus to form plate-to-plate connection; or the wire harness is matched with an electronic wire harness terminal for use to form board-to-wire connection; can also be independently used for connecting the plates.

The existing pin header on the market is also a heightened product, but the length of the long pin is simply lengthened to achieve the heightening effect, so that the defects brought by the heightening effect are obvious, and the connection stability is poor.

The present application was made based on this.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned defect that exists among the prior art, the utility model provides a heighten row needle has better steadiness.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

a heightening row needle comprises a first rubber core, a second rubber core and a third rubber core which are sequentially arranged up and down, and two rows of lengthened first long needles and second long needles which penetrate through the first rubber core, the second rubber core and the third rubber core and are arranged at equal intervals front and back; the first long needle and the second long needle respectively comprise a first connecting end and a second connecting end; the length of the first connecting end extending out of the first rubber core is greater than the length of the second connecting end extending out of the third rubber core.

Preferably, in order to balance the stress on the pin header and further improve the overall stability, the first rubber core, the second rubber core and the third rubber core have the same distance.

Preferably, in order to ensure the conductivity of the connector, the first long needle and the second long needle are made of copper alloy or nickel-base gold-plated material.

Preferably, in order to ensure the flame retardant performance of the rubber core, the first rubber core, the second rubber core and the third rubber core are made of PA9T +30% glass fiber materials.

The utility model has the advantages of: the utility model discloses the row's needle that increases can be used for the connection between the great PCB board of two intervals, welds behind the PCB board of second link (shorter one end) disect insertion below of row's needle, and first link (longer one end) is used for inserting row's mother that is located on the PCB board of top. The structure through double three moulds makes the utility model discloses the row needle has fine steadiness as the connector. And the heightened pin header is used for connecting two PCB boards, one board is connected with the pin header, and the heightened pin header is connected to the pin header, so that the plugging and unplugging are facilitated.

Description of the labeling: the needle comprises a first long needle 11, a second long needle 12, a first connecting end 21, a second connecting end 22, a first rubber core 31, a second rubber core 32 and a third rubber core 33.

Detailed Description

In order to make the technical means and the technical effects achieved by the technical means of the present invention clearer and more complete, the following embodiments are provided and are described in detail with reference to the accompanying drawings as follows:

as shown in fig. 1 to 3, the heightened row needle of the embodiment includes a first rubber core 31, a second rubber core 32, and a third rubber core 33 arranged in sequence from top to bottom, and two rows of lengthened first long needles 11 and second long needles 12 penetrating through the first rubber core 31, the second rubber core 32, and the third rubber core 33 and arranged at equal intervals from front to back; the first long needle 11 and the second long needle 12 both comprise a first connecting end 21 and a second connecting end 22; the length of the first connecting end 21 extending out of the first rubber core 31 is greater than the length of the second connecting end 22 extending out of the third rubber core 33. The heightened row bus bar can be used for connecting two PCB boards with larger space, the second connecting end 22 (shorter end) of the row pin is directly inserted into the PCB board below and then welded, and the first connecting end 21 (longer end) is used for being inserted into the row bus bar on the PCB board above. The structure of moulding through two triples makes this embodiment row needle have fine steadiness as the connector.

In this embodiment, the first rubber core 31, the second rubber core 32 and the third rubber core 33 have the same distance, so that the stress of the pin header is balanced, and the overall stability is further improved.
