Description

Technical Field

[0001] The present application relates to the field of electrical components, and in particular to a small pin header automotive connector. Background Art

[0002] Pin header is a type of connector. This type of connector is widely used in PCB circuit boards in electronics, electrical appliances, and instruments. Its function is to act as a bridge between blocked or isolated circuits within the circuit, and to take on the task of current or signal transmission.

[0003] In the related art, a double-row pin connector includes a connector body and pins arranged on the connector body, and the pins are arranged in two rows on the connector body. Since the spacing between the pins is small and the pins are relatively thin, the pins are easily bent by external forces during use, causing the pins in the upper and lower rows to overlap and collide, affecting normal use. Summary of the invention

[0007] By adopting the above technical solution, needle caps are put on the pins, and multiple pins are fixed by the needle caps, so that multiple pins are connected together by the needle caps, which can effectively prevent the pins from bending, improve the stability of the pins, prevent the pins from colliding, and facilitate use.

[0008] Optionally, a latching protrusion is provided at a position close to the middle of the pin corresponding to the needle cap, and the latching protrusion abuts against the hole wall of the needle hole.

[0009] By adopting the above technical solution, a locking protrusion is provided on the pin, and the locking protrusion can limit the position of the needle cap on the pin, thereby preventing the needle cap from being displaced.

[0010] Optionally, two clamping protrusions are symmetrically arranged on the pin.

[0011] By adopting the above technical solution, the clamping protrusions are symmetrically arranged on the pins, so that the forces on both sides of the pins are evenly applied, thus preventing the pins from bending.

[0012] Optionally, the needle seat includes an upper row seat and a lower row seat which are detachably connected to each other, and the two rows of pins are respectively arranged on the upper row seat and the lower row seat.

When in use, the upper seat and the lower seat are assembled together, which can effectively prevent the pins on the upper seat and the lower seat from bending and colliding.

[0014] Optionally, a plurality of groups of plug-in holes and plug-in blocks that plug into and fit with each other are provided on one side of the upper row seat and the lower row seat that are close to each other.

[0015] By adopting the above technical solution, the assembly structure between the upper row of seats and the lower row of seats is simple and easy to use.

[0020] Optionally, detection holes are provided through the positions of the upper seat and the lower seat corresponding to the pins.

[0021] By adopting the above technical solution, detection holes are opened on the upper and lower seats. After the connector is installed, the detection holes can be used to check whether each pin is connected correctly before power is turned on; at the same time, the detection holes can improve the heat dissipation efficiency of the pins.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0032] The following is combined with Figure 1-5 This application is described in further detail.

[0033] The present application embodiment discloses a small pin header automotive connector, referring to Figure 1 , including a needle seat 1 and pins 2, the pins 2 are L-shaped pins 2, and the pins 2 are fixed on the needle seat 1 in two rows.

[0034] Reference Figure 2 and Figure 3 A needle cap 3 is installed on the pin 2. The needle cap 3 is an insulating cubic block. Pin holes 31 are formed on the needle cap 3 at positions corresponding to all pins 2. The pins 2 are inserted into the pin holes 31. A clamping protrusion 21 is integrally formed near the middle of the pin 2. The clamping protrusion 21 is arranged corresponding to the position of the needle cap 3. Two clamping protrusions 21 are symmetrically arranged on both sides of the pin 2. After the pin 2 is inserted into the needle cap 3, the clamping protrusion 21 is clamped on the hole wall of the pin hole 31 to prevent the needle cap 3 from displacement.

[0035] Reference Figure 2 and Figure 5The pin seat 1 includes an upper seat 11 and a lower seat 12, and two rows of pins 2 are fixed on the upper seat 11 and the lower seat 12 respectively; a cylindrical plug-in block 111 is integrally formed on one side of the upper seat 11 close to the lower seat 12, and a plug-in hole 121 is opened at a position corresponding to the plug-in block 111 on the lower seat 12, and the plug-in block 111 is plugged and matched with the plug-in hole 121; the plug-in block 111 and the plug-in hole 121 are distributed in multiple groups along the arrangement direction of the pins 2. When in use, the upper seat 11 or the lower seat 12 can be used as a single-row connector, or assembled before use.

[0036] Reference Figure 2 and Figure 4 A snap-fitting ridge 112 is integrally formed on the outer wall of the plug-in block 111. The snap-fitting ridge 112 is a ridge arranged along the length direction of the plug-in block 111. The cross-sectional profile of the snap-fitting ridge 112 is triangular. There are multiple snap-fitting ridges 112 evenly distributed along the circumference direction of the plug-in block 111. When in use, after the plug-in block 111 is inserted into the plug-in hole 121, the snap-fitting ridge 112 will be slightly embedded in the hole wall of the plug-in hole 121 to improve the connection strength.

[0037] Reference Figure 2 and Figure 5 A stopper 113 is formed integrally at one end of the upper seat 11 and the lower seat 12.
