[ detailed description ] embodiments

In the following description, for purposes of explanation, numerous implementation details are set forth in order to provide a thorough understanding of the various embodiments of the present disclosure. It should be understood, however, that the specific details of the various implementations are not to be interpreted as limiting the disclosure. That is, in some embodiments of the disclosure, details of the various implementations are not necessary. In addition, for the sake of simplicity, some conventional structures and elements are shown in the drawings in a simple schematic manner.

Fig. 1 is a side view of a probe fixing assembly 100 according to an embodiment of the present disclosure. As shown, the probe fixing assembly 100 includes a support rod 110, a telescopic rod 120, and a collet 130. The retractable rod 120 is pivotally connected to the support rod 110. The collet 130 is located at an end of the telescopic rod 120 away from the supporting rod 110 for holding the probe. The telescopic rod 120 includes an accommodating portion 122 and an extending portion 124. The accommodating portion 122 is pivotally connected to the support rod 110, the accommodating portion 122 has a first thread 123 therein, and the extending portion 124 extends from the accommodating portion 122.

Fig. 2 is a front view of the collet 130 of the probe fixing assembly 100 of fig. 1, viewed from direction D. Fig. 3 is a front view of collet 130 of fig. 2 as

buttons

133a, 133b are depressed. Referring to fig. 2 and 3, the collet 130 includes a housing 131,

buttons

133a and 133b, and

elastic clamping members

134a, 134b, 134c, and 134 d. The housing 131 has an inner wall surface 131a and an outer wall surface 131b facing each other, and the inner wall surface 131a surrounds the accommodating space 132. For the sake of clarity of the structure of the collet 130, each element of fig. 2 and 3 is shown by a solid line, but actually, an element portion between the inner wall surface 131a and the outer wall surface 131b may be shielded by the housing 131. The

buttons

133a and 133b protrude from the outer wall surface 131b of the case 131.

Elastic clips

134a, 134b, 134c, 134d protrude from the inner wall surface 131a of the housing 131 into the accommodating space 132, the

elastic clips

134a, 134b are connected to the button 133a, and the

elastic clips

134c, 134d are connected to the button 133 b.

When the

buttons

133a and 133b are pressed by the force F, the

elastic clamping members

134a, 134b, 134c and 134d contract towards the inner wall surface 131a and store elastic potential energy, so that the probe can be accommodated in the accommodating space 132, as shown in fig. 3. There is sufficient space between the

resilient clips

134a, 134b, 134c, 134d for the probe to be received. When the

buttons

133a, 133b are released, the

elastic holding pieces

134a, 134b, 134c, 134d are respectively moved in a direction away from the inner wall surface 131a by the elastic potential energy, as shown in fig. 2. At this time, the space between the

elastic holding members

134a, 134b, 134c, 134d is reduced, and the probe can be held.

In this embodiment, the collet 130 further includes

pulleys

136a, 136b, 136c, 136d,

connection lines

137a, 137b, and

connection rods

138a, 138 b.

Pulleys

136a, 136b, 136c, 136d are located in the housing 131. The connection line 137a is provided on the

pulleys

136a and 136b, and is passed through the inner wall surface 131a and fixed to the tops of the

elastic clamps

134a and 134 b. The connection line 137b is provided on the

pulleys

136c and 136d, and is fixed to the tops of the

elastic clamps

134c and 134d by passing through the inner wall surface 131 a. The connecting rod 138a has both ends fixed to the connecting line 137a between the button 133a and the

pulleys

136a and 136b, respectively. The connecting rod 138b has both ends fixed to the connecting line 137b between the button 133b and the

pulleys

136c and 136d, respectively. In the present embodiment, the connection wire 137a and the connection wire 137b of the collet 130 are steel wires, but not limited thereto.

In the present embodiment, the

buttons

133a and 133b of the collet 130 are symmetrically disposed on the outer wall surface 131b of the housing 131. The

elastic clamping pieces

134a and 134c are symmetrically disposed in the accommodating space 132, and the

elastic clamping pieces

134b and 134d are symmetrically disposed in the accommodating space 132. Such a configuration is beneficial for stability when holding the probe.

When the

push buttons

133a and 133b are pressed by the force F, the

push buttons

133a and 133b respectively drive the connecting

rods

138a and 138b to move toward the accommodating space 132. At this time, the connecting rod 138a presses the connecting line 137a between the

pulleys

136a and 136b, so that the connecting line 137a pulls the

elastic clamping members

134a and 134b into the inner wall surface 131a (i.e., moves toward the outer wall surface 131 b), and stores elastic potential energy. Similarly, the connecting rod 138b may press the connecting wire 137b between the

pulleys

136c, 136d such that the connecting wire 137b pulls the

elastic clamping members

134c, 134d into the inner wall surface 131 a. In this way, there is enough space between the

elastic clamping members

134a, 134b, 134c, 134d to receive the probe, as shown in fig. 3. When the

push buttons

133a and 133b are released, the

elastic holding pieces

134a, 134b, 134c, 134d are respectively moved in a direction away from the inner wall surface 131a by the elastic potential energy. At this time, the

elastic clips

134a and 134b pull the connection line 137a, and the button 133a is moved in a direction protruding from the outer wall surface 131b by the force of the connection line 137 a. Similarly, the

elastic clamping members

134c and 134d pull the connecting wire 137b, so that the button 133b is forced by the connecting wire 137b to move in the direction of protruding the outer wall surface 131 b. In this way, the probe can be clamped between the

elastic clamping members

134a, 134b, 134c, 134d, as shown in fig. 2.

In this embodiment, the probe fixing assembly 100 further includes

cushion pads

139a, 139b, 139c, 139 d. A cushion 139a is located on top of resilient clip 134a, a cushion 139b is located on top of resilient clip 134b, a cushion 139c is located on top of resilient clip 134c, and a cushion 139d is located on top of resilient clip 134 d. In the present embodiment, the

cushion pads

139a, 139b, 139c, 139d may be made of rubber, but not limited thereto. The

cushion pads

139a, 139b, 139c, 139d can increase the friction force with the probe when the

elastic clamping pieces

134a, 134b, 134c, 134d clamp the probe, thereby preventing the probe from falling.

Referring to fig. 1, in the present embodiment, the accommodating portion 122 of the telescopic rod 120 has a first thread 123 therein, and the surface of the extending portion 124 of the telescopic rod 120 has a second thread 125 coupled to the first thread 123. Since the first thread 123 and the second thread 125 are coupled, the extension 124 can be rotated out of the accommodating portion 122 or the extension 124 can be rotated into the accommodating portion 122 from the outside by rotating the extension 124. By rotating the extension part 124, the total length of the telescopic rod 120 can be adjusted. Thus, when the collet 130 holds the probe, the extension 124 can be rotated to adjust the position of the probe.

In this embodiment, the telescoping rod 120 further comprises a positioning member 126. The positioning member 126 is locked to the accommodating portion 122 and abuts against the extending portion 124. When the extension part 124 is adjusted to a proper length, the positioning member 126 locked to the accommodating part 122 can be rotated, so that the positioning member 126 abuts against the extension part 124 to fix the extension part 124, thereby preventing the length of the telescopic rod 120 from being changed in the process of measurement. In addition, the telescoping rod 120 also includes a knob 128. The retractable rod 120 can pivot on the supporting rod 110. An included angle Θ is formed between the supporting rod 110 and the telescopic rod 120. After the included angle Θ is adjusted, the knob 128 passing through the accommodating portion 122 can be locked to the supporting rod 110 to fix the accommodating portion 122.

Fig. 4 is a partially enlarged view of the clamp 140 of the probe fixing assembly 100 of fig. 1. Referring to fig. 1 and 4, the probe fixing assembly 100 further includes a clamp 140, and the clamp 140 is disposed at an end of the supporting rod 110 away from the telescopic rod 120. The clamp 140 includes an elastic member 141, an upper plate 142, a lower plate 144, and a screw 146. The upper plate 142 has screw holes 148. The lower plate 144 is disposed opposite the upper plate 142. The screw 146 is locked to the screw hole 148 and protrudes toward the lower plate 144.

In the embodiment, the probe fixing assembly 100 can fix the clamp 140 to the edge of the motherboard or the operation platform, so that the probe clamped by the collet chuck 130 can be positioned at the test point of the motherboard to be tested, which not only saves labor, but also improves the accuracy of measurement. When the clamping device 140 is used, the upper plate 142 and the lower plate 144 of the clamping device 140 (e.g., the right ends of the upper plate 142 and the lower plate 144 in fig. 4) are pressed to compress the elastic member 141, and the clamping device 140 can approach the main board or the console to be located between the upper plate 142 and the lower plate 144. When the upper plate 142 and the lower plate 144 of the clamp 140 are released, the upper plate 142 and the lower plate 144 are abutted against the edge of the motherboard or the console by the elastic force of the elastic member 141. In this state, the screw 146 penetrating through the upper plate 142 can be rotated, so that the bottom of the screw 146 abuts against the edge of the main board or the operation table, thereby further improving the stability.

In this embodiment, the clamp 140 further includes

cushions

143, 145. The

cushion pads

143, 145 are located on the bottom surface of the upper plate 142 and the top surface of the lower plate 144, respectively. The

cushion pads

143, 145 may be made of rubber, but not limited thereto. The

buffer pads

143 and 145 on the upper plate 142 and the lower plate 144 can be used as the contact surfaces between the clamp 140 and the edge of the motherboard or the console, and the friction force can be increased by the

buffer pads

143 and 145, so that the stability is improved, and the shock absorbing capability is provided.

In the present embodiment, the jig 140 further includes a cushion 147. A cushion 147 is located on the bottom surface of the screw 146. After the upper plate 142 and the lower plate 144 are fixed to the edge of the motherboard or the console, the screws 146 may be rotated to make the cushion 147 abut against the edge of the motherboard or the console, so as to increase the pressure and increase the friction force, thereby achieving a more complete fixing effect. The material of the cushion pad 147 may be rubber, but is not limited thereto.

In this embodiment, the clamp 140 further includes a weight 149. The weight 149 is located on the bottom surface of the lower plate 144. In this embodiment, the counterweight may be an iron block, but is not limited thereto. By adding the weight member, the weight of the probe fixing assembly 100 is more concentrated on the portion of the bottom clamp 140 (i.e., the effect of the downward movement of the center of gravity), so as to further improve the stability of the probe fixing assembly 100.

Although the present disclosure has been described with reference to particular embodiments, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present disclosure, and it is intended that the scope of the present disclosure be limited only by the terms of the appended claims.
