The positive pin 121 and the negative pin 123 are electrically connected to the chip respectively. The positive pin 121 and the negative pin 123 are respectively exposed from the housing 110. A connecting column 111 is provided on the housing 110. The conductive member 130 connects the positive pin 121, the negative pin 123 and the connecting column 111 respectively. Since a loop is formed between the housing 110, the pin 120 and the chip. When any one of the chip and the pin 120 generates static electricity, the static electricity can be released through the housing 110, so that the chip is protected from static electricity interference, the risk of the chip being broken down by static electricity is reduced, and the safety of the laser module 100 is improved.

[0045] The arrangement of the connecting column 111 facilitates the electrical connection between the conductive member 130 and the housing 110.

The number of windings of the linear connection strip is not limited as long as a stable and reliable electrical connection can be achieved.

[0048] Optionally, an elastic part 137 is connected between the first connection part 131 and the second connection part 133, and an elastic part 137 is connected between the second connection part 133 and the third connection part 135. The setting of the elastic part 137 can better adapt to the distance between the positive pin 121, the connecting column 111 and the negative pin 123, ensuring stable and reliable connection. In this embodiment, the elastic part 137 adopts a spiral spring, so that the distance between the first connection part 131 and the second connection part 133 can be adjusted by stretching or shortening, and the distance between the second connection part 133 and the third connection part 135 can be adjusted by stretching or shortening. Of course, the elastic part 137 can also adopt a plurality of U-shaped, V-shaped, W-shaped spring structures connected in sequence or a wavy spring structure, which can also achieve stretching or shortening for distance adjustment, facilitating stable and reliable electrical connection between the first connection part 131 and the positive pin 121, between the second connection part 133 and the connecting column 111, and between the third connection part 135 and the negative pin 123.

[0049] The first connection part 131, the second connection part 133 and the third connection part 135 can be bent into a circular ring, an arc or a hook shape, so as to be conveniently connected to the columnar pin 120 and the connecting column 111. The first connection part 131, the second connection part 133 and the third connection part 135 can be integrally formed or separately fixedly connected with the elastic part 137, which is not specifically limited here. Of course, the connection method of the first connection part 131, the second connection part 133 and the third connection part 135 to the pin 120 and the connecting column 111 can be welding or other connection methods.

[0050] Combination Figure 3 The conductive member 130 further includes a first connecting piece 140. The first connecting portion 131, the second connecting portion 133 and the third connecting portion 135 are clips, respectively, and the three clips are electrically connected to the first connecting piece 140. The three clips clamp the positive electrode pin 121, the negative electrode pin 123 and the connecting column 111 respectively.

[0051] Optionally, each clip includes a first clamping segment 141 and a second clamping segment 143 that are arranged opposite to each other. The first clamping segment 141 and the second clamping segment 143 are separated from each other by a certain distance at one end close to the pin 120 or the connecting column 111 to form a clamping groove. The size of the clamping groove is adapted to the size of the pin 120 or the connecting column 111, so as to facilitate the pin 120 or the connecting column 111 to be inserted into the clamping groove. The first clamping segment 141 and the second clamping segment 143 are separated from each other at one end close to the first connecting piece 140, and are respectively connected to the first connecting piece 140 to improve the stability of the connection. The first clamping segment 141 and the second clamping segment 143 are close to each other in the middle section to improve the structural strength of the entire clip. The middle section here refers to the portion between the end connected to the first connecting piece 140 and the end forming the clamping groove.

[0052] The three clips have similar structures and shapes. The lengths of the middle sections are different only to adapt the positions of the pins 120 and the connecting pillars 111. The first connecting piece 140 and the three clips can be integrally formed or connected separately, which is not specifically limited here.

[0053] Combination Figure 4 , the conductive member 130 also includes a connecting block 150, and the three clips are electrically connected to the connecting block 150 respectively. The shell 110 is disposed on the connecting block 150. In this embodiment, at least one surface of the shell 110 of the laser module 100 is in contact with the connecting block 150. This increases the contact area between the shell 110 and the connecting block 150, making the electrical connection more stable and reliable, and the electrostatic release effect better. One end of the three clips is connected to the pin 120 or the connecting column 111 respectively, and the other end is connected to the connecting block 150. The structural shape of the clip is similar to Figure 3 The shape of the clip structure is similar to that of the embodiment of the present invention, and will not be described in detail here.

[0054] Of course, the structure of the clip is not limited to the above-mentioned cases, and can be columnar, strip, block, spherical, spiral or wavy, etc., as long as electrical connection can be achieved.

The second connecting piece 160 is electrically connected to the shell 110. The second connecting piece 160 includes a fourth connecting portion 165 and a fifth connecting portion 167. The fourth connecting portion 165 is electrically connected to the positive pin 121, and the fifth connecting portion 167 is electrically connected to the negative pin 123. Among them, the positive pin 121 exposes the fourth connecting portion 165, and the negative pin 123 exposes the fifth connecting portion 167. This arrangement makes it convenient for the test power supply 200 to be electrically connected to the positive pin 121 and the negative pin 123 respectively during the power-on test.

[0056] The second connection piece 160 includes a first end 161 and a second end 163 that are oppositely disposed, and a middle section 164 that is connected between the first end 161 and the second end 163. The middle section 164 is provided with a fourth connection portion 165 and a fifth connection portion 167. At least one of the first end 161, the second end 163, the middle section 164, the fourth connection portion 165, and the fifth connection portion 167 is in contact with the housing 110 to achieve electrical connection between the housing 110 and the second connection piece 160.

[0057] In this embodiment, the first end 161 and the second end 163 are bent and connected to two opposite surfaces of the housing 110 respectively, so as to improve the stability and reliability of the electrical connection and ensure the effective discharge of static electricity.

[0058] Optionally, the fourth connection portion 165 and the fifth connection portion 167 may be a linear connection strip, a columnar structure or a clip structure. The first end 161 and the second end 163 are bent into an arc shape, and the arc-shaped outer surface contacts the surface of the housing 110 to achieve electrical connection. For example, the arc-shaped outer surface and the surface of the housing 110 are connected by abutment, welding, bolt connection or screw connection, which is not specifically limited here. In this structure, the structure of setting the connection column 111 on the housing 110 is omitted, and the structure is simpler, and the assembly is faster and more convenient.

[0059] Optional, see Figures 1 to 5 As shown, the ends of the positive electrode pin 121 and the negative electrode pin 123 extending out of the housing are respectively exposed free ends, so as to facilitate electrical connection with the test power supply 200 .

[0060] It is easy to understand that the above-mentioned various structural forms can be combined with each other to form more different implementation methods, which are not listed one by one here.

[0061] Combination Figure 6 The embodiment of the utility model also provides a laser testing system, including a test power supply 200 and a laser module 100 as any one of the aforementioned embodiments, and the test power supply 200 is electrically connected to the pin 120. Optionally, the test power supply 200 includes a positive output terminal 210 and a negative output terminal 220. The positive output terminal 210 is electrically connected to the positive pin 121. The negative output terminal 220 is electrically connected to the negative pin 123. Optionally, the test power supply 200 is connected to the positive pin 121 and the negative pin 123 respectively by plugging and unplugging, which is quick and convenient to operate. Among them, Figure 6 The conductive member 130 in the laser module 100 shown in the figure takes the structure of the second connecting piece 160 as an example, and the test bench 230 has a grounding characteristic, which is convenient for conducting and releasing static electricity.

[0062] It should be noted that after the preparation of the laser module 100 is completed, a power-on test is required. In the prior art, when power is applied, the static electricity material needs to be removed first, and then the power supply and the pins are electrically connected for testing. Since there may be static electricity between the output end of the power supply and the pins, the static electricity is released instantly when the power supply is inserted, which may easily cause the laser module to have no power as a whole or the chip to fail. In this embodiment, in the laser module 100, a loop is formed between the shell 110, the pins 120 and the chip. If there is static electricity between the test power supply 200 and the pins 120, or between the internal chip and the leads, after the output end of the test power supply 200 and the pins 120 are electrically connected, the static electricity will be discharged through the shell 110, effectively completing the static electricity release. After the static electricity is released, remove the conductive member 130 to Figure 6 Taking the structure as an example, the second connecting piece 160 needs to be removed before the power-on test is performed, which is beneficial to reduce the discharge risk and avoid the problem of the chip being broken down by static electricity or being interfered by static electricity.

[0063] The conductive member 130 in this embodiment has a simple structure, reliable electrical connection, convenient assembly and disassembly, and high power-on test efficiency.

[0064] In summary, the laser module 100 provided in the embodiment of the utility model has the following beneficial effects:

[0065] The laser module 100 provided by the embodiment of the utility model forms a loop between the housing 110, the pins 120 and the chip. If static electricity is generated on the chip or the pins 120, the static electricity can be discharged from the housing 110, effectively realizing static discharge, reducing the risk of the chip being broken down by static electricity or being interfered by static electricity, and improving the safety of the laser module 100. The conductive member 130 has flexible and diverse structural forms, is easy to connect, has stable and reliable electrical connections, and is flexible in application scenarios and has good compatibility.
